To simplify automatic assembly the position of the second housing part (24) to the first housing part (20) in relation to a second angle (β) is rigidly fixed, and the shape of the opening (28) in the brake booster housing (12) and the cross-sectional shape of the first connecting piece (22) are matched to each other in such a way that a rotation of the first connecting piece (22) in the opening (28) of the brake booster housing (12) is at least substantially prevented. ...
USPTO Applicaton #: #20090293713 - Class: 91358 R (USPTO) - Related Terms: Booster The Patent Description & Claims data below is from USPTO Patent Application 20090293713, Vacuum brake booster with an improved connecting element for connection to a vacuum source.
Said auxiliary force is generated by a pressure differential in the housing of the brake booster which acts on a moving wall which is arranged between a working chamber and a vacuum chamber of the brake booster. To control the level of the pressure differential, and therewith the size of the auxiliary force generated by the brake booster, a control valve is used which on the one hand can connect the working chamber of the brake booster to atmospheric pressure (or with overpressure) and on the other hand can connect the vacuum chamber of the brake booster to the working chamber.
An embodiment of a vacuum brake booster according to the invention will be described in more detail hereinafter with reference to the accompanying, schematic drawings, in which:
FIG. 3 shows the view III-III from FIG. 2.
The two housing parts 20 and 24 are made from plastics material in the embodiment shown in the figures, preferably by injection moulding. At its end remote from the first connecting piece 22 the first housing part 20 has a circular ring-shaped end face 36 which together with a circular ring-shaped end face 38 of the same size on the second housing part 24 determines a connecting plane in which the two housing parts 20 and 24 abut each other. In this connecting plane the two housing parts 20 and 24 can be rotated relative to each other about a second angle β in order to be able to adjust a desired angle β which the second connecting piece 26 should have relative to the first connecting piece 22. For this purpose the desired angle of rotation β is adjusted during manufacture of the connecting element 16, at which angle the second connecting piece 26 extends in the desired orientation with respect to the first connecting piece 22 fixed in the opening 28. The two end faces 36 and 38 are then welded by means of ultrasound, so the position of the second housing part 24 relative to the first housing part 20 is accordingly rigidly fixed while maintaining the desired angle β. Instead of welding with ultrasound, gluing of the two end faces 36 and 38, crimping of the two housing parts 20 and 24 in the region of the two end faces 36 and 38 or interlocking latching which guarantees that the adjusted angle β is maintained may also be considered.
