Gear-reduction starter with built-in coaxial switch

Abstract

The invention provides a gear-reduction starter with a built-in coaxial switch. The gear-reduction starter with the built-in coaxial switch comprises a machine case, a motor, a speed reducer and an output shaft, and further comprises an electromagnetic assembly, a shift ring, a shift fork and a contactor assembly, wherein the motor, the speed reducer and the output shaft are arranged in the machine case and are in transmission connection in sequence, the electromagnetic assembly is arranged on the output shaft in a sleeving manner, the electromagnetic assembly and the output shaft are arranged coaxially, the shift ring is in transmission connection with the electromagnetic assembly, the shift fork is used in cooperation with the shift ring, the contactor assembly is used in cooperation with the shift fork, the output shaft is in transmission connection with the electromagnetic assembly, and the contactor assembly is electrically connected with the motor. Compared with a traditional technical scheme according to which an electromagnetic assembly is arranged aside, because the electromagnetic assembly is arranged on the output shaft in the sleeving manner, and the electromagnetic assembly and the output shaft are coaxially arranged, the gear-reduction starter with the built-in coaxial switch is relatively smaller in size.

Description

technical field [0001] The invention relates to a vehicle starter, in particular to a deceleration starter with a built-in coaxial switch. Background technique [0002] The starter is a device used to start the car engine. With the rapid development of car technology, the engine compartment of the car is not only equipped with the main body of the engine and the starter, but also has a lot of functional components such as the transmission, which is provided for the starter. The installation position of the starter is getting smaller and smaller. How to install the starter in a limited space without removing other functional components is a problem that plagues the development of automobiles. [0003] Existing starters mainly include three parts: electric motor, transmission mechanism and control structure, wherein the control structure is usually a side electromagnetic switch, that is, the electromagnetic switch is usually arranged next to the motor or transmission mechanism...

AI Technical Summary

Problems solved by technology

[0003] Existing starters mainly include three parts: electric motor, transmission mechanism and control structure, wherein the control structure is usually a side electromagnetic switch, that is, the electromagnetic switch is usually arranged next to the motor or transmission mechanism, which needs to occupy a large space, so that The relatively large size of the starter

[0004] In addition, the moving iron core on the electromagnetic switch of the existing starter usually needs to be connected with the output shaft through a shift fork and a shift ring that cooperate with each other. The ring and the shift fork are transmitted to the moving iron core, which makes the moving iron core vibrate, drives the moving contact fixedly connected with the moving iron core to vibrate, and affects the stability of the electrical contact between the moving contact and the static contact
