Embodiment Construction

[0013] exist figure 1 A preferred embodiment of the actuating or starting device according to the invention is schematically shown in longitudinal section. The housing 10 of the starting device consists of a cylindrical housing part 11 and a cover 13 , which are connected to one another by screws, not further shown. The cylindrical housing part 11 is closed at the rear by a cover 13 , in the middle of which a closure cap 14 is provided. In the drawing shown, the closure cap 14 extends substantially in the shape of a cap over the entire rear wall of the housing 10 and corresponds to the cover 13 . However, the closure cap 14 and the cover 13 can of course also be arranged separately.

[0014] The rear end 17A of the drive shaft 17 of the electric starter motor 18 , the armature of which is designated 19 , is covered by the closure cover 14 . Radially outside the armature, a plurality of permanent magnets 20 of the starter motor are arranged on the wall of the housing part 11...

Abstract

The present invention relates to a starting device used for a combustion engine. The starting device has a starting motor arranged in a shell (10), a drive shaft (17) of the starting motor is axially fixed on an end part at a rear part relative to the shell (10) by means of a maintaining disc (51), wherein a part of the drive shaft (17), which is protruded outside the maintaining disc (51), is covered by a closed cover (200). The closed cover (200) has at least one moulding part (201) which is arranged at an inner part and used for loading the maintaining disc (51).

Description

technical field [0001] The invention relates to a starting device for an internal combustion engine according to the preamble of claim 1 . Background technique [0002] Starting devices for internal combustion engines, so-called starters or starters, are known in the prior art. For example, DE 298 01 079 U1 shows a starting device of this type with a starter motor arranged in a housing, the drive shaft of which is held at the rear end relative to the housing by means of The disk is axially fixed. The holding disk is substantially U-shaped and is arranged in a groove of the drive shaft. The holding disk is displaceable not only axially but also radially, that is to say not without play. As a result, when the starting device is in operation, the retaining disk can be rotated rapidly and at the same time strike the housing or the closure cap that closes the housing, thereby damaging the housing or the closure cap. For example, it may happen that the closure cap is detached....
