The invention relates to a drive device for a flap of a vehicle, with a connectable to a fixed component or a movable member first fastener and with an opposite end to the first fastener axially relative thereto movable housing tube 1, which at its the first fastener opposite Having a fastener with the movable member or the stationary component fastened second fastener. A spindle drive has a threaded spindle 8 and a spindle nut 9 arranged on the threaded spindle 8, wherein the first fastening element and the housing tube 1 can be driven axially relative to one another by the spindle drive. In this case, the spindle drive is rotatably driven by an electric motor 21, through whose output shaft, the threaded spindle 8 or a coupling component of a clutch is rotatably driven. The electric motor 21 is arranged in the housing tube 1, forming on the inner wall of the housing tube 1, a stator 22, radially circumferentially evenly distributed two or more field magnets are arranged, which surround a coaxial thereto, rotatably mounted rotor shaft 19, on, a rotor 23 forming coils 25 are arranged.
The The invention relates to a drive device in particular for one Flap of a vehicle, with one with a fixed component or a movable component connectable first fastener and with one opposite to the first fastener End axially relative to the movable housing tube, which at his the first fastener opposite end one with the movable Component or the fixed component fastened second fastener has, with a threaded spindle and arranged on the threaded spindle Spindle nut having spindle drive through which the first fastener and the housing tube axially movable relative to each other are movable, wherein the spindle drive is rotatably driven by an electric motor, through its output shaft the threaded spindle or a coupling component of a clutch rotatable is drivable.
at Such drive devices, it is known the electric motor as complete independent Unit with own motor housing and in the housing tube install.
This requires not only many components but also a special care during assembly of the electric motor, around this coaxial with the threaded spindle or a coupling in the housing tube to arrange.
task The invention is therefore a drive device of the beginning to create type mentioned, which has a small number of components and allows easy installation.
These Task is inventively characterized solved, that the Electric motor in the housing tube is arranged, forming a stator on the inner wall of the housing tube Radially distributed evenly distributed two or more field magnets or coils are arranged, the one To coaxially rotatably mounted rotor shaft enclose, on forming a rotor coils or evenly distributed radially circumferentially two or more field magnets are arranged.
By This training can be dispensed with a separate motor housing, which reduces the number of required components and training allows the drive unit with a small diameter.
The housing tube Fulfills thus a double function.
There the rotor shaft of the electric motor so, as well as the threaded spindle or a coupling component can be stored directly in the housing, there is no misalignment of these parts.
The Field magnets can be either permanent magnets or even electromagnets.
at Coils arranged on the rotor are preferably on the rotor shaft a collector connected to the coils arranged on the fixed Sliding contacts are in plant.
The Threaded spindle can with its one end to the housing tube rotatably mounted and opposite the housing tube axially fixed and rotatable by the electric motor be driven and connected to the first fastener Spindle nut can opposite the housing tube be secured against rotation.
These Training leads that the Spindle nut torque is supported within the drive device and not over the fasteners on the movable member and the fixed Supported component must become.
This allows it is the drive means in any orientation on the to fix the movable component and the fixed component, whereby the mountability of the drive device considerably simplified.
In simple and easy to produce way, the housing tube by forming such as e.g. Deep drawing made metal component or by injection molding be manufactured plastic part.
In simple way, the spindle nut with one end of a Threaded spindle coaxially enclosing Spindle tube be connected at the other end, the first fastener is fixed.
Also the spindle tube may be made by forming, e.g. Deep drawing made Metal component or manufactured by injection molding plastic part.
to Reduction of speed and increase of the torque, the spindle drive via a gear from the electric motor be rotatable drivable.
is the gearbox a spur gear and / or a planetary gear, so only a small noise emission occurs, which is further minimized when the dretriebtriebnahen stages of the gearbox as helical teeth Steps are formed.
For a simple and in any rotational position to the longitudinal axis of the drive device montier Baren execution leads, if one or both of the fasteners are a ball head or a ball socket of a ball joint.
to power assistance the drive device and thus a flap weight balance as well as to a small dimensioning of the rotary drive it leads when the first fastener of a spring force in the extension direction from the housing tube is acted upon or acted upon.
This can over the entire Verstellhub or only over part of the Verstellhubes respectively.
To is in a simple embodiment, the first fastener of a supported on the housing tube compression spring, in particular a helical compression spring acted upon.
alternative or in addition For this purpose, the first fastening element can also be acted upon by a gas pressure be.
The Power that needed If the spindle is to be moved manually, it is preferably exactly the same selected that the The flap is held in intermediate positions with the rotary drive deactivated can be. Thus, in electromotive rotary drive an electroless Stop position easily realizable.
to Decoupling of the electric motor from the spindle drive, the spindle drive via an openable Clutch of the electric motor to be rotatably driven.
These Coupling can be a positive or a frictional Be clutch.
To the Engagement and disengagement, the clutch can be a shiftable clutch, in particular be a switchable magnetic coupling.
On However, a special clutch drive can be dispensed with if the clutch is loaded when unloaded or in the extension direction Drive device open and by loading the drive device closable in the retraction direction Clutch is.
This leads up easy way to a manual mobility with comfortable hand forces in the pulling direction of the drive device, because then the electric motor and possibly the gear can not act inhibiting on the spindle.
There no tensile forces transmitted can be results in an optimal obstacle detection and obstacle switching when closing the Flap.
Of the Flap weight balance is preferably designed so that always a resulting moment acts in the closing direction. That means, that the Drive device must always be able to open the door motor. To close the flap only be drained at a defined rate.
At the housing tube may be arranged a the spindle tube with distance enclosing guide tube.
Encloses it the helical compression spring the guide tube by far and is also a distance from one with the first Fastener connected overtube enclosed, so the helical compression spring is both led as also radially inwards and outwards protected.
One Protection of the components of the drive device against contamination and damage is achieved by the housing tube and the overtube telescopically slidable.
to easy manual operation with good efficiency is the Threaded spindle a multi-speed Spindle preferably with a pitch between about 10 mm and 24 mm.
