Embodiment Construction

[0017] figure 1 The starting device is shown in longitudinal section. exist figure 1 The starting device 10 is shown in . The starter device is designed as a starter device in which the starter pinion is surrounded by a part of the starter device housing. The following embodiments also apply to cantilevered starters, ie starters in which the starter pinion is exposed over its entire circumference after actuation of the pre-engagement actuator.

[0018] exist figure 1 The starter device 10 shown in FIG. 2 has, for example, a starter motor 13 and a pre-engagement actuator 16 . The starter motor 13 and the pre-engagement actuator 16 are fastened to a common drive end bearing cover 19 . The starter motor 13 is used to drive the starter pinion 22 when the starter pinion 22 engages in the gear ring of the internal combustion engine, which is not further shown here.

[0019] The starter motor 13 has a pole tube 28 as a housing, which has a plurality of pole pieces 31 on its inn...

Abstract

The seal has a rubber bellow (214) provided for sealing an inner area of a toe-in actuator and fastened to a housing (156) by using a deformable covering ring (210), where the rubber bellow has a cylindrical middle section. The covering ring is accommodated in a recess of a drive end bearing housing (19). The recess is graded in such a manner that movement possibility of the ring in a direction is limited by a circumferential surface between two layers of the recess, where breadth of the ring is smaller than the breadth of a collar for accommodating the rubber bellow at the housing.

Description

technical field [0001] The invention relates to a sealing device for a pre-engagement actuator, in particular a sealing device for a starter relay of a starting device for an internal combustion engine. Background technique [0002] To start the internal combustion engine, a drive is used, which is powered by a power source separate from the fuel supply system. In most cases, a DC motor is used for this purpose, the drive pinion of which is first moved into the gear ring of the internal combustion engine in order to subsequently start the internal combustion engine. This is done, for example, by means of a starter which works on the principle of a push screw drive. After the starting process is complete, the drive pinion is moved out of the gear ring of the internal combustion engine again. [0003] DE10124506A1 relates to a starter for a motor vehicle. The starter comprises a hollow housing, a pre-engagement actuator containing an electromagnetic switch, and a rotatably ...
