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 starter (1) is provided with an electric drive motor, which drives a drive shaft (5), where a lock washer (13) is held positively on the shaft of the starter. The lock washer is formed annular. The lock washer is adjusted between two cross-sectional geometries. The inner diameter of the lock washer changes during the adjustment. The locking washer has a curved shape in the former cross-sectional geometry. The lock washer is executed as sticking washer.

Description

technical field [0001] The invention relates to a starter for an internal combustion engine having a drive motor which drives a drive shaft which is the carrier of a starter pinion on which the starter pinion is mounted is adjustable, wherein a stop plate is positively fixed on the shaft of the starter. 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 t...
