Problems solved by technology

[0003] Once the internal combustion engine starts, the faster motor rotation causes the ring gear to overshoot the starter pinion, causing the starter pinion to be thrown out of the ring gear

Embodiment Construction

[0023] In the figures, the same components are denoted by the same reference numerals.

[0024] figure 1 The starter 1 for an internal combustion engine shown in , has a starter pinion 2 which meshes with a ring gear 3 of the internal combustion engine in order to start the internal combustion engine 4 . The starter pinion 2 is supported axially displaceably on the drive shaft 5 , as indicated by the double-headed arrow, wherein the starter pinion 2 is coupled to the drive shaft 5 in a rotationally fixed manner. The starter pinion 2 is adjusted between the retracted parking position and the forward meshing position with the ring gear 3 of the internal combustion engine 4 via a switch-on relay 6 which is designed electromagnetically and which comprises An energizable relay coil 7 and a reciprocating armature 8 which axially enters into the relay coil 7 when the relay coil 7 is energized. The reciprocating armature 8 forms a dynamic coupling with the starter pinion 2 via the s...

Abstract

The invention relates to a starter used for a combustion motor, the starter is provided with a drive motor, the drive motor drives a drive shaft, the drive shaft is a carrier of a pinion of the starter, and the starter pinion is adjustable on the drive shaft. A shaft of the starter is fixed with a circular spacing sheet in a cooperated shape, and the spacing sheet can be adjusted between a first cross section geometrical shape and a second cross section geometrical shape. And an inner diameter of the spacing sheet is changed when being adjusted.

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] DE 43 02 854 C1 discloses a starter for an internal combustion engine which has a drive motor whose motor shaft drives a drive shaft via a transmission, on which a starter pinion is arranged. The starter pinion is adjusted via a switching relay between an axially retracted position and an axially advanced position, in which the starter pinion meshes with the ring gear of the internal combustion engine. By operating the drive motor, the starter pinion turns and drives the ring gear of the internal combustion engine. [0003] Once the internal combustion engine starts, the increased rotation of the electric motor causes the ring gear to overrun the starter pinion, causing the starter pinion to fling out of the ring gear. During such an axial return movement, the drive shaft also generates an axial impulse in the dire...
