Abstract: A shaft unit, has a shaft having an axis, a gear wheel mounted mounted on the shaft, the gear wheel having a flange and a first bore formed in the flange the shaft having a second bore which is a continuation of the first bore, the first and second bores have the same axis extending perpendicularly to the shaft of the axis and also having the same diameter, and damping device having a spring sleeve composed of elastic material extending in the first and second bore and inserted in the first and second bores in a form-locking fashion between the shaft and the gear wheel, the spring sleeve acting as a force-transmitting and damping member.

Abstract: The starting device for an internal combustion engine includes a housing, an electrical drive motor (10) with a drive shaft (16), a starting pinion (12) for engagement with a rim gear of the engine and an intermediate gear (11) making an operative connection between the drive shaft and the starting pinion. For damping or absorption of the shocks and preventing fractures arising from the compression stroke of the starting engine the starting pinion (12) is connected directly or indirectly nonrotatably with the gear shaft (24) of the intermediate gear (11) and the gear shaft (24) is coupled with a hollow wheel (21) via an elastic damping ring (34). The drive shaft (16) meshes with its outer toothing (19) in the internal toothing (20) of the hollow wheel. The hollow wheel (21) is received in a bearing (25) in the housing and the damping ring (34) is made of rubber or plastic, is inserted in the hollow wheel (21) and, surrounds the gear shaft (24 ).

Abstract: To provide for axial alignment of the shaft of a starter motor, the shaft is formed with a ring groove (17) and a pair of half-disks (18) positioned between a holding plate (12) of the brush holder and the end shield (6) of the starter retains the half-disks in position, the half-disks engaging in the groove to thus position the axial location of the starter shaft (3).

Abstract: To reliably hold a movable contact bridge carrier on a longitudinally slidable contact stem in position, even though subjected to severe vibration and shock, while still permitting free longitudinal movement of the stem carrying the contact carrier, the stem is passed through an opening formed in the magnetic yoke of the operating solenoid, and a clamping bushing, for example of tough, elastically deformable plastic, such as nylon, is placed in position to surround the stem where it passes through the opening, the bushing having spreader elements which extend radially outwardly to resiliently bear against the inner surface of the opening, the spreader elements merging into a cylindrical portion of the bushing surrounding the stem to hold the stem in centered, vibration and shock-absorbing position within the opening in which it is longitudinally movable.

Abstract: An adjusting device for controlling the position of a gas lever in a motor vehicle in cooperation with a speed controlling servo-mechanism arranged in the vehicle for delivering a control signal, comprises an electromotor energized by the control signal, a shaft supported on a support for rotation about its axis and for movement along its axis, an electromagnetic coupling having a disc-shaped armature rotatably supported on the shaft and an electromagnetic member fixedly connected to the shaft. The electromagnetic member of the coupling is energized by the control signal to engage with the armature. A first reduction gear is arranged between the electromotor and the armature. A locking arm is pivotably supported on the support and linked at its free end to the gas lever and, at its other end, to the second reduction gear.
