- the pinion is directed towards the bearing by the tightening force of a Screw pressed. This is located on the threaded section.
- the pinion, the output shaft and the bearing are fixed such that the thrust receiving surface and the end surface of the pinion on the bearing side clamp the inner ring of the bearing.
- the starting actuator constantly engages with a toothed ring, wherein the toothed ring can be coupled to the crankshaft of the internal combustion engine via an overrunning clutch or can be decoupled from this.
- a sprocket is mounted on the crankshaft of the internal combustion engine.
- the ring gear may be relatively movable to the crankshaft, so that the ring gear is stationary while the internal combustion engine is running.
- the above-mentioned first embodiment of the invention is based on the idea that basic interventions in the drive train of a motor vehicle are required. Consequently, the aforementioned first embodiment variant can initially only be used in smaller numbers.
- the above adaptation i. E. The elimination of the freewheel and the Eingurmechanismus' for small numbers usually no cost advantage, but means additional effort that would inevitably be reflected in the product cost.
- a standardized starting device while maintaining the freewheel and maintaining an engagement mechanism is modified to the effect that the Ritzelruureage the drive pinion of the starting device is displaced by means of a spacer such that the drive pinion constantly in engagement with the ring gear of the internal combustion engine which is disposed on the crankshaft, is engaged.
- the engagement mechanism still comprises an engagement relay, which, however, comprises a changed rest position and a reduced engagement path. This means a reduction of the noise and a lower contact bounce, since a reduced maximum speed is achieved when engaging.
- the relay winding can be selected according to the required specifications.
- the starting device in particular arranged by the output shaft of the electric drive drive pinion, arranged closer to the ring gear of the internal combustion engine down.
- the output shaft of the electric drive drive pinion arranged closer to the ring gear of the internal combustion engine down.
