Problems solved by technology

[0004] In the prior art, the general one-way clutch deceleration assembly is mainly completed by axial stacking and assembly of the one-way device, planetary shaft, planetary gear, pinch ring and other parts, which will cause the axial direction of the one-way clutch deceleration assembly. The overall length is very long, which will take up a lot of space for the starter motor

Abstract

The invention discloses a car starting motor and a one-way clutch structure thereof. The car starting motor comprises the one-way clutch structure, the one-way clutch structure comprises a fixed sleeve ring, an inner gear ring and a planet shaft, and the inner gear ring is assembled on the inner wall of the fixed sleeve ring. One side of the planet shaft is provided with an end face flange, a plurality of evenly-distributed planet gears are mounted in the circumferential direction of the end face flange, and the planet shaft with the planet gears is sleeved with the inner gear ring by means ofthe end face flange and then assembled in the fixed sleeve ring in a centralized mode. In this way, according to the car starting motor and the one-way clutch structure thereof, a one-way clutch mounting structure can be optimized, the axial distance of the one-way clutch assembly is greatly shorted, and the overall size of the starting motor is reduced.

Description

technical field [0001] The invention relates to the technical field of an automobile starter motor, in particular to an automobile starter motor and a one-way clutch structure thereof. Background technique [0002] The one-way clutch deceleration assembly of the automobile starter motor is an important part of the starter motor. As long as it is a starter motor, there will be such a one-way clutch deceleration assembly inside. [0003] The power required by the starter motor when starting the engine is decelerated through this type of one-way clutch reduction assembly and then increased torque to complete power transmission, so the one-way clutch reduction assembly is an important part of the starter motor. [0004] In the prior art, the general one-way clutch deceleration assembly is mainly completed by axial stacking and assembly of the one-way device, planetary shaft, planetary gear, pinch ring and other parts, which will cause the axial direction of the one-way clutch de...
