Solenoid switch wear-resistant core for automotive starters

Abstract

The invention provides a solenoid switch wear-resistant core for automotive starters. The solenoid switch wear-resistant core for automotive starters is provided with a steel casing and an end cover. The end cover is sleeved to the surface of the steel casing. A moving core body is disposed in the steel casing. A wear-resistant layer is disposed on the outer surface of the moving core body. A chromed protective layer is effectively antioxidant and is durable and wear-resistant, and accordingly the moving core is better protected by the chromed protective layer. Utilization rate of the automotive starter is increased, and the automotive starter is also protected.

Description

technical field [0001] The invention relates to an automobile component, in particular to an electromagnetic switch wear-resistant iron core for an automobile starter. Background technique [0002] Present automobile engines all start and work in advance by a starter, and the starter mainly includes a DC motor, a magnetic switch and a one-way clutch. The working tasks of the magnetic switch are as follows: one is to push the one-way clutch to slide forward along the drive shaft according to the command issued by the ignition switch, and to mesh with the large wheel disc of the engine; the other is to connect or disconnect the power supply of the DC motor. The working tasks of the one-way clutch: one is to transmit the power of the DC motor to the large wheel of the engine, and the other is to block the power of the engine from returning to the DC motor when the engine is started. At present, the existing magnetic switch is a cymbal-fork structure. When this structure is wor...

Problems solved by technology

Obviously, this complex reverse linkage mechanism and relatively demanding control accuracy lead to the starter working in a critical state between normal and abnormal.

[0003] The moving iron core provided in the existing automobile starter, due to the high utilization rate and frequent friction of the moving iron core, the wear rate of the moving iron core is high, and the moving iron core is the core component of the automobile starter. If some parts are damaged too quickly, the life of the car starter will be shortened and the work efficiency will be affected.
