- the remaining way to the front groove end of the starter pinion is driven by the screw force between the guide pin and the Nutinnendinn the screw groove.
- the Vorspur accent is relieved.
- the starter pinion Upon reaching the front groove end of the screw groove, the starter pinion is fully meshed with the ring gear on the engine and assumes its driving state in which the ring gear is driven. In this situation, no forces act on the Vorspur beautifully.
- the ring gear drives the starter pinion and a driving moment is transmitted from the ring gear to the starter pinion.
- the guide pin is pressed against the abutment surface adjacent to the front groove end on the groove inner wall of the screw groove.
- the Vorspur noticed is relieved of forces.
- the Vorspur responded to pulls the starter pinion in the direction of their Außerfunktions- or home or rest position.
- the guide pin leaves the abutment surface on the groove inner wall, the helical shape of the screw groove accelerates the ejection of the starter pinion.
- the guide groove is introduced into the lateral surface of the drive shaft and the guide pin is connected to the starter pinion.
- the starter pinion is designed as a hollow body, which is pushed onto the drive shaft.
- the guide pin protrudes radially into the inner recess in the starter pinion in order to perform the desired engagement in the screw groove on the lateral surface of the drive shaft can.
- the guide pin is connected to the drive shaft and protrudes radially from the lateral surface of the drive shaft and engages in a guide groove which is formed on the inside of the starter pinion.
- an axial Montagewhisnut is provided on the same component, in which also the screw groove is introduced.
- the Montageosnut extending in the axial direction is arranged in the feed direction in front of the screw groove and opens into the screw groove.
- the Montageosnut has a smaller radial depth than the screw groove, the front groove end of the screw groove bordering the Montageosnut.
- the Montageosnut allows axial sliding of the starter pinion with inserted guide pin, which extends at least slightly radially in the inner passage of the starter pinion.
- the guide pin is moved along the Montageosnut until reaching the fferennut, which has a greater radial depth, so that the guide pin can protrude with greater radial depth in the screw groove.
- the screw groove extends in the circumferential direction at least slightly beyond the Montageosnut addition, wherein in the transition between the Montageosnut and the screw groove, the front groove end of the screw groove is formed at the in the regulä- Ren starter position of the guide pin rests and is supported.
