Problems solved by technology

However, diameter reduction is limited due to the torque required for the starting process that must be transmitted via the drive shaft to the pinion shaft and the starter pinion

Embodiment Construction

[0022] exist figure 1 and 2 The starter 1 shown in is used for starting an internal combustion engine and has a motor-driven drive shaft 2 and a pinion shaft 3 with a starter pinion 5 . The pinion shaft 3 is embodied as a hollow shaft in which the drive shaft 2 is accommodated. The pinion shaft 3 has an end-side carrier section 4 which is the carrier of the starter pinion 5 , wherein the starter pinion 5 is embodied as a separate component from the pinion shaft 3 and can be used as a socket The gear is pushed onto the end-side carrier section 4 of the pinion shaft 3 . To start the internal combustion engine, the starter pinion 5 with its outer toothing 6 engages with the ring gear of the internal combustion engine during the meshing process.

[0023] The pinion shaft 3 is supported on the drive shaft 2 in an axially displaceable and rotatable manner about a shaft longitudinal axis 11 . This support is achieved by means of two bearings 7 and 8 on the inner wall 12 of the ho...

Abstract

The invention relates to a starter for an internal combustion engine, comprising a pinion shaft axially displaceably mounted on a drive shaft and being a starter pinion. In order to axially limit the feed displacement of the pinion shaft, a stop device having a stop ring is provided on the drive shaft and a stop counterpart is provided on the pinion shaft. The stop counterpart is implemented as a separately implemented component that can be attached to the inner face of the pinion shaft. The starter pinion forms an insert pinion that can be placed on a lateral carrier segment of the pinion shaft.

Description

technical field [0001] The invention relates to a starter for an internal combustion engine according to the preamble of claim 1 . Background technique [0002] Known from document DE 41 27 742 A1 is a free cantilever starter (frei aussto βender Starter) for an internal combustion engine, which has a small starter pinion bearing on the drive shaft in an axially displaceable manner. The gear shaft, the starter pinion interacts with the ring gear of the internal combustion engine. To start the internal combustion engine, the switch-on relay is switched on, which pushes the pinion shaft axially forwards and simultaneously rotates it by engaging the lever, following which the starter pinion on the pinion shaft meshes with the ring gear of the internal combustion engine middle. At the same time, the switch contact is closed, with which the starter motor is switched on, which drives the drive shaft including the pinion shaft via the planetary gear. [0003] The pinion shaft is ...
