Steering column (1) for a motor vehicle, wherein the steering column (1) comprises a steering spindle bearing unit (2) and a steering spindle (4) rotatably mounted about a steering spindle longitudinal axis (3) in the steering spindle bearing unit (2) and one for fastening the steering column (1) in the motor vehicle provided support unit (5) on which the steering shaft bearing unit (2) is held, and the steering spindle bearing unit (2) has a thread (6) and by means of a motor (7) along the steering spindle longitudinal axis (3) relative to the support unit (5) is adjustable, wherein the steering shaft bearing unit (2) for their adjustment along the steering spindle longitudinal axis (3) relative to the support unit (5) by means of at least one drive belt (8) or at least one drive chain to the motor (7).
The present invention relates to a steering column for a motor vehicle according to the preamble of patent claim 1.
In generic steering columns, the position of the steering wheel in the direction of the steering spindle longitudinal axis by means of a motor is adjustable to adjust the position of the steering wheel attached to the steering wheel to the respective vehicle driver.
From the DE 689 10 204 T2 the use of a belt drive for height adjustment of the steering column is known. The DE 37 37 225 C1 shows a chain drive for height adjustment of the steering column.
A generic steering column is z. B. in the DE 36 36 315 A1 shown. In this document, the steering shaft bearing unit has a sleeve rotatably mounted on its outer surface. This carries the thread and engages in a fixed to the support nut. To set this sleeve in rotary motion, an electric motor is provided, which drives the sleeve via a worm to rotate about the steering spindle longitudinal axis. By rotating this sleeve in the fixed arranged on the support nut, there is an adjustment of the steering shaft bearing unit together with the steering shaft in the direction of the steering spindle longitudinal axis.
The object of the invention is to provide an alternative, quiet as possible, but also little space consuming type of drive the steering shaft bearing unit for their adjustment in the direction of the steering spindle longitudinal axis by means of the engine.
For this purpose, the invention provides a steering column according to claim 1.
This is characterized in that the steering spindle bearing unit for its adjustment along the steering spindle longitudinal axis relative to the support unit by means of at least one drive belt or at least one drive chain is connected to the motor and a nut engages in the thread and either this nut by means of the drive belt or the drive chain is rotatable or this nut is non-rotatably fixed to the support unit or otherwise motor vehicle rotationally fixed and the steering shaft bearing unit has a sleeve rotatably mounted about the steering spindle longitudinal axis, which carries the thread of the steering shaft bearing unit, wherein the sleeve is non-displaceable in the direction of the steering spindle longitudinal axis with respect to the other parts of the steering shaft bearing unit, wherein the sleeve is drivable by the motor by means of the drive belt or the drive chain.
A basic idea of the invention is thus to transmit the rotational movement of the motor via at least one drive belt or at least one drive chain to the steering spindle bearing unit, so that it is displaced in the direction of the longitudinal axis of the steering spindle relative to the support unit, if it is driven accordingly by the motor.
The engine is preferably an electric motor. The steering spindle is preferably telescopic. For example, it may have at least two steering spindle sections, which non-rotatably engage with each other, but in the direction of the steering spindle longitudinal axis relative to each other, preferably in one another, are displaceable. The part or the portion of the steering shaft, which carries the steering wheel connection for attaching the steering wheel, is conveniently mounted in the steering shaft bearing unit so that it is rotatable about the steering spindle longitudinal axis, but not in the direction of the steering spindle longitudinal axis against the steering shaft bearing unit.
This type of training and storage of the steering shaft in the steering shaft bearing unit is known per se in the prior art and need not be further explained.
It is expediently provided that the motor has a drive rotor with which it engages on the drive belt or on the drive chain. The steering shaft bearing unit may be designed to be telescopic as well as the steering shaft. In this context, it is advantageous if the steering spindle bearing unit is designed in several parts, wherein the parts of the steering shaft bearing unit are arranged telescopically interlocking in the direction of the steering spindle longitudinal axis and the threaded part of the steering shaft bearing unit closest to a steering wheel connection of the steering shaft. The said parts of the steering shaft bearing unit may be like the entire steering shaft bearing unit formed like a tube and engage around respective sections of the steering shaft or encase.
The thread, which serves to adjust the steering spindle bearing unit in the direction of the steering spindle longitudinal axis, is mounted in preferred embodiments on the outside of the steering shaft bearing unit. It is thus preferably an external thread. Alternatively, it is also possible that the said thread is an internal thread mounted inside the steering spindle bearing unit. The steering spindle bearing unit is usually tubular and encases the one or more rotatably mounted portions of the steering shaft. By means of the steering spindle, the rotational movement of the steering wheel is transmitted to the steering gear and thus to the corresponding wheels provided for steering the vehicle. Conveniently that is In any case, thread circumferentially around the steering shaft bearing unit formed circumferentially. It may, but does not necessarily have to be formed over the entire circumferential direction. It is Z. B. also possible to form the thread in the form of spaced apart in the circumferential direction of the steering shaft bearing unit threaded portions. These threaded portions are preferably formed strip-shaped. Their longitudinal extent conveniently runs parallel to the steering spindle longitudinal axis. In order to transmit the rotational movement caused by the motor on the drive belt and / or the drive chain to the thread of the steering spindle bearing unit, a nut is provided. The nut engages in the thread of the steering spindle bearing unit. The nut is rotatable in a first variant of the invention by means of the drive belt or the drive chain. The thread can be arranged non-rotatably fixed to the steering shaft bearing unit. Advantageously, the thread is formed by a plurality, at least three, threaded portions, of which preferably one or more threaded portions are slidably fixed in the direction of the longitudinal axis on the casing pipe. In this case, at least one individual, preferably exactly one single threaded section, should be arranged immovably on the jacket tube in the longitudinal direction, while the other threaded sections are arranged so as to be displaceable in the longitudinal direction. The displacement is advantageously limited to the distance between the second threads to each other.
To illustrate the invention is advantageously a belt tensioning system, which is not illustrated here in the figures provided.
Since it is ultimately only important for the movement of the steering shaft bearing unit in the direction of the longitudinal axis of the steering spindle that the nut and steering spindle bearing unit perform a rotation relative to one another, the alternative alternative is that the nut is non-rotatably attached to the support unit or otherwise secured to the motor vehicle in a rotationally fixed manner is. The steering shaft bearing unit then has, as per se in the DE 36 36 315 A1 shown, a rotatably mounted about the steering spindle longitudinal sleeve, which carries the thread of the steering shaft bearing unit. This sleeve is then, just as in the DE 36 36 315 A1 shown, not displaceable in the direction of the steering spindle longitudinal axis relative to the other parts of the steering shaft bearing unit. The drive of this rotatable sleeve of the steering shaft bearing unit is then again by means of the drive belt or the drive chain from the engine. In these cases, therefore, the thread is arranged non-rotatably fixed only on the sleeve, but not on the other parts of the steering shaft bearing unit. In any case, preferred embodiments of the invention provide that the nut has an internal thread and engages with this internal thread in the thread of the steering spindle bearing unit. As already explained, it is also conceivable that the nut has an external thread, if just the steering shaft bearing unit has an internal thread. In the sense of a space-saving design, it is in any case favorable if the steering spindle bearing unit is passed through the nut. In order to prevent the steering spindle bearing unit from rotating about the longitudinal axis of the steering spindle, preferred embodiments of the invention provide for the steering spindle bearing unit to be mounted non-rotatably in the support unit relative to the steering spindle longitudinal axis by means of a rotation lock. The rotation prevents the steering spindle bearing unit is rotated about the steering spindle longitudinal axis relative to the support unit.
Steering columns according to the invention can also have energy absorbing elements or devices for the crash case, ie in the event of an accident. Such Energieaufzehrungselemente for the crash case are basically known in the most varied embodiments in the prior art. In any case, preferred embodiments of the invention provide for the steering spindle bearing unit to be held on the support unit with the interposition of a slide, wherein the carriage with the steering spindle bearing unit is displaceably mounted on the support unit with the interposition of an energy absorption element for the event of a crash.
In addition, steering columns according to the invention can of course also allow a height adjustment of the steering spindle or steering spindle bearing unit relative to the support unit. This can be operated purely by hand, but also designed to be operated by a motor. Particularly preferred embodiments of the invention provide in this context that the steering column according to the invention comprises a height adjustment motor, which z. B. drives corresponding height adjustment spindles.
Further features of variants according to the invention are explained by way of example with reference to an exemplary embodiment of the invention in the following description of the figures. Show it:
1 and 2 perspective views of the steering column of this embodiment;
3 a side view of the steering column;
4 the section along the section line AA 3 and
5 to 8th Detailed representations of the inventive embodiment of this embodiment.
In the 1 and 2 is the embodiment of a steering column according to the invention shown here 1 in perspective views once from diagonally above and the other time shown from diagonally below. 3 shows the steering column 1 in a side view. It is in the embodiment shown here is a so-called electrically adjustable steering column. So the steering spindle bearing unit 2 together with the steering spindle 4 along the steering spindle longitudinal axis 3 in the longitudinal directions 36 by means of the engine 7 be adjusted. For height adjustment in the height directions 37 serves the height adjustment motor 26 , These are each electric motors. In principle, it is also possible to use other motors in order to realize the adjusting possibilities described in detail below.
The steering spindle 4 is about its steering spindle longitudinal axis 3 rotatable in the steering shaft bearing unit 2 stored. As a rule, the steering spindle 4 formed in several parts. It usually also includes joint parts, such as the fork shown in the example 4a to form a universal joint, not shown. The individual sections or parts of the steering spindle 4 are mutually rotationally fixed, but relative to each other in the longitudinal direction displaceable, preferably arranged telescopically. This is known per se to the steering shaft 4 shorten in the event of a crash. On average according to 4 you can see the two rotationally interlocking parts of the steering shaft 4 , The bearing of the steering spindle 4 in the steering shaft bearing unit 2 does not need to be explained. Suitable types of bearings are known in the art. To a steering wheel, not shown here on the steering shaft 4 To attach, this has a steering wheel connection 16 on. Furthermore, it should be noted that the part of the steering shaft 4 , which the steering wheel connection 16 has, so in the steering wheel side part 17 the steering shaft bearing unit 2 is rotatably mounted, that said part of the steering shaft 4 and the part 17 the steering shaft bearing unit 2 longitudinal 36 are not displaced relative to each other. In the illustrated embodiment, the steering shaft bearing unit 2 from two relative to each other in the longitudinal direction 36 So along the steering spindle longitudinal axis 3 movable, here also telescopically interlocking parts 17 and 18 educated. The part 17 points to the steering wheel connection 16 , The part 18 leads to the steering assistance unit 19 , The latter can, as known in the art, be formed. This can be the steering assistance 19 both a translation of the means of steering wheel in the steering shaft 4 introduced steering angle cause, as is known under the term superposition steering, as well as a torque assist effect, as is known under the term power steering. Such steering supports 19 are known in the art and need not be further explained here. However, the invention is also applicable to steering columns without steering assistance. The steering column according to the invention can also be used in steer-by-wire steering systems or in steering systems in which the steering assistance takes place at a different position in the motor vehicle, for example in the steering gear.
The steering spindle 4 can also in part 18 the steering shaft bearing unit 2 be rotatably mounted. Will the steering spindle 4 rotatably mounted otherwise, but so can both the storage in the part 18 as well as the part 18 the steering shaft bearing unit 2 completely eliminated.
The carrying unit 5 can by means of fastening straps 21 be attached to the body of the motor vehicle. It serves as a carrier of the steering spindle bearing unit 2 , In the illustrated embodiment, the steering shaft bearing unit 2 not directly but indirectly with the interposition of the carriage 13 and the intermediate part 23 on the carrying unit 5 held. Between the sled 13 and the carrying unit 5 is in a conventional manner a Energieaufzehrungselement 14 arranged, which serves the reduction of impact energy in the event of a crash, ie in the event of a vehicle collision. As an energy-absorbing element 14 In principle, all types of such elements known in the prior art come into question. In the illustrated embodiment, the Energieaufzehrungselement 14 formed in the form of a bending tab. The one leg of the bending tab is on the support unit 5 fixed. The other leg of the bending tab is on the slide 13 fixed. In the event of a crash, the sled 13 together with the steering spindle bearing unit 2 and the steering spindle 4 towards the front wheels of the vehicle, ie towards the attachment tabs 21 shifted, whereby by appropriate deformation, as well as possibly with an additional associated cutting, the Energieaufzehrungselementes 14 the impact energy is dissipated.
For height adjustment in height directions 37 is the steering shaft bearing unit 2 together with the steering spindle 4 pivotable about the pivot axis 20 on the carrying unit 5 suspended. In the illustrated embodiment, this pivotal suspension takes place via the rocker 22 and the steering assistance 19 as well as the separately on the carriage 13 suspended intermediate part 23 , Of course, this is just an example and can be done quite differently. For height adjustment itself is the steering shaft bearing unit 2 not directly but with the interposition of the intermediate part 23 on the sledge 13 attached. The intermediate part 23 can work together with the steering spindle bearing unit 2 and therefore also with the steering spindle 4 in height directions 37 relative to the sled 13 be adjusted. To do it during this height adjustment not to tilt the intermediate part 23 in the sledge 13 comes, a slot guide is provided in this embodiment. This is especially good in the side view 3 to see. It is a slot-like guide 30 in the sledge 13 in which a guide pin 29 of the intermediate part 23 slidably guided. It is conceivable and possible to form such a guide in another way or, if it is not needed, to dispense with it. The height adjustment motor itself serves for height adjustment 26 which is one of the height adjustment spindles 24 directly and the other height adjustment spindle 24 over the timing belt 25 indirectly drives. The height adjustment spindles 24 each with their thread in one of the height adjustment nuts 27 one. These height adjustment nuts 27 are each on the sled 13 fixed. All this is best on average 4 along the section line AA 3 to see. By turning the height adjustment motor 26 Both are height adjustment spindles 24 turned. Through their threaded engagement in the height adjustment nuts 27 it depends on the direction of rotation of the height adjustment spindles 24 to an upward or downward movement in the height direction 37 , bringing the intermediate part 23 together with the steering spindle bearing unit 2 and the steering spindle 4 in the sledge 13 raised or lowered and thus the desired height adjustment in the height direction 37 is realized. In the embodiment shown, two height adjustment spindles 24 , one right and one left of the sled 13 used to lateral tilting of the intermediate part 23 in the sledge 13 to avoid. In the realization of appropriate guides can of course also on one of the height adjustment spindles 24 be waived. Other embodiments of the height adjustment, as are well known in the art, are conceivable and possible, and can be combined with the steering column according to the invention.
To realize the length adjustment according to the invention in the direction of the longitudinal directions 36 or along the steering spindle longitudinal axis 3 is provided that the steering shaft bearing unit 2 a thread 6 which, in the embodiment shown as an outside of the steering shaft bearing unit 2 arranged external thread is realized. The steering spindle bearing unit 2 and thus also the steering spindle 4 are for their adjustment along the longitudinal spindle longitudinal axis 3 relative to the support unit by means of a drive belt 8th with the engine 7 connected. The thread 6 is in the embodiment shown in the form of in the circumferential direction 9 the steering shaft bearing unit 2 distanced from each other strip-shaped threaded sections 10 realized. The strip-shaped threaded sections 10 are through executions 38 in the middle part 23 passed. The interaction of threaded sections 10 and bushings 38 can also act as anti-rotation, which prevents the steering shaft bearing unit 2 or her part 17 which the thread 6 contributes to the steering spindle longitudinal axis 3 relative to the intermediate part 23 twisted. It can also be realized any other type of rotation, z. B. a journal or tongue and groove guide between the steering shaft bearing unit 2 or their part 17 and the intermediate part 23 ,
To further explain the longitudinal adjustment according to the invention along the steering spindle longitudinal axis 3 or the longitudinal direction 36 is now in particular on the 4 to 8th directed. 4 shows the section along the section line AA 3 ,
In 5 are big parts of the steering column 1 not shown, so that the intermediate part 23 , the engine 7 and the steering shaft bearing unit 2 or their part 17 good looks. In 6 is then also the intermediate part 23 omitted. The 7 and 8th only show the mother 11 with the drive belt 8th and the drive rotor 15 of the motor 7 ,
The steering spindle bearing unit 2 or their part 17 is in the illustrated embodiment by the mother 11 passed, with one at the mother 11 realized internal thread 12 in the form of the threaded sections 10 trained external thread 6 the steering shaft bearing unit 2 or its part 17 intervenes. The mother 11 is by means of the drive belt 8th rotatable. For this purpose, the engine engages 7 with its drive rotor 15 on the drive belt 8th on, or in this one. In the illustrated embodiment, the mother wears 11 for the interaction with the drive belt 8th an external toothing 31 into which the belt toothing 32 intervenes. In this embodiment also carries the drive rotor 15 a corresponding external toothing 33 to get into the belt toothing 32 also be able to intervene positively. Alternatively, the rotational movement of the engine 7 or its drive rotor 15 on the mother 11 take place in other ways. If appropriate frictional forces are provided, z. B. also the belt teeth 32 and the external teeth 31 and 33 omitted. The use of a drive chain as a replacement for the drive belt 8th is possible. However, the use of a toothed belt is preferable, since it is very quiet in operation and has only a low weight and can transmit sufficiently high torques even with relatively low tolerance requirements.
The mother 11 is apart from the crash case in position along the steering spindle longitudinal axis 3 , ie along the longitudinal direction 36 , not adjustable. In the embodiment shown, it is for this purpose in a corresponding longitudinal direction 36 limited recess in the intermediate part 23 rotatably mounted. This ensures that when turning the nut 11 the part 17 the steering shaft bearing unit 2 longitudinal 36 is moved while the mother 11 seen in this direction, rests.
In the 5 illustrated game setting 28 serves to play the steering spindle bearing unit 2 or their part 17 in the middle part 23 to be limited to the necessary level or to be able to adjust accordingly.
In the illustrated embodiment, the mother wears 11 two guide rings 34 , as a thrust bearing, and a spring washer 35 which is at least one of the guide rings 34 in the direction of the steering spindle longitudinal axis 3 against the main body 39 mother 11 biases. This serves to release the mother from play 11 in longitudinal directions 36 in the middle part 23 , This type of Spielfreistellung may possibly be omitted or be designed in a different way. The guide rings 34 In addition to the function of the axial bearing, the function of the radial bearing can also be assumed. It is also conceivable and possible to represent the axial and / or radial bearing by roller bearings, which can then replace the guide rings.
