Embodiment Construction

[0018] figure 1 The starter device 100 shown is known from the document DE 10 2012 210 682 A1 mentioned at the outset. The starter device 100 can generally also be referred to as an electric machine by means of which the internal combustion engine can be started or started. For this purpose, the starter device 100 has a relay 42 embodied as a switching relay or as a switching relay.

[0019] The housing 10 of the starting device 100 is formed from a cylindrical housing part 11 and a cover part 13 , which are connected to each other by screws, not further shown. The cylindrical housing part 11 is closed at the rear by a cover part 13 , in the middle part of which a closed hub 14 directed outwards is formed. In the hub 14 there is a bearing point 15 in which the rear end 17a of the drive shaft or armature shaft 17 of the starter motor 18 is mounted, the armature of the starter motor 18 being designated with 19 . Radially outside the armature 19 , a plurality of permanent magn...

Abstract

The invention relates to a starter device for an internal combustion engine, which has a freewheel (33) arranged on a starter pinion (35), which protrudes axially onto the starter pinion (35) There are clamping rollers (82) in the clamping space (81) between the inner ring (34) of the driving member (89) and the outer ring (37) of the driver (89) and the clamping space (81) of the freewheel mechanism is at the end The side is defined by the guide disc (87), wherein the closing cap (75) with the positioning disc (88) embedded in the outer ring (37) in the form of a form-fit connection has a small axial gap in the axial direction. Fix the guide plate (87) and starter pinion (35) on the freewheel mechanism (33). The puck (88) has a smaller diameter than the guide disk (87) and an annular shoulder (92) enveloping the puck (88) protrudes from the guide disk (87) at the outer edge (91).

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] As a starting device for an internal combustion engine, a starter motor is known for short, which has a starter pinion driven in the manner of an electric motor, which can be activated by means of a starter relay, which can also be called a switching relay Move axially into drive position. In the drive position, the starter pinion engages in the ring gear for starting the internal combustion engine. [0003] DE 10 2012 210 682 A1 discloses a starter device for an internal combustion engine, which has a starter pinion drivable via a freewheel mechanism. The freewheel mechanism comprises clamping rollers which are arranged in clamping spaces which are closed off at the end by guide discs. The guide disc is held on the freewheel mechanism by the positioning disc and the closing cap covering the positioning di...
