Embodiment Construction

[0030] Some preferred embodiments of the present application are described below with reference to the accompanying drawings.

[0031] figure 2 An electromagnetic switch for use in a vehicle starter according to an embodiment of the present application is shown in .

[0032] First of all, it needs to be pointed out that when describing the electromagnetic switch of the present application, the word "front" indicating the orientation refers to the side close to the vehicle engine in the axial direction, and "rear" refers to the side away from the vehicle engine in the axial direction. .

[0033] This electromagnetic switch comprises housing 2, and it has substantially cylindrical body 2a and is arranged at this body front end ( figure 2 The left end in the center, the end toward the vehicle engine side) the front end wall 2b, the front end wall is formed with a central axial through hole.

[0034] In the rear portion of the body 2a of the housing 2, an electromagnet core 4...

Abstract

The invention discloses an electromagnetic switch used in a vehicle starter. The electromagnetic switch comprises a housing which limits an axial direction, a cover potion which supports a pair of binding posts and has a front end fixed in the housing, an electromagnetic core which is installed in the housing and is disposed on the front surface of the end portion, and an elastic element which is axially provided with a maximum elasticity compression amount and is clamped between the cover portion and the electromagnetic core by a pres-elasticity compression amount smaller than the maximum elasticity compression amount, wherein the front side of the electromagnetic core is supported by the housing, and the rear side of the electromagnetic core is supported by the elastic element. The invention further discloses a vehicle starter comprising the electromagnetic switch. According to the invention, the axial movement of the cover portion can be reduced.

Description

technical field [0001] The present application relates to an electromagnetic switch used in a vehicle starter and a vehicle starter comprising such an electromagnetic switch. Background technique [0002] The starter of a motor vehicle is usually composed of an electric motor, a transmission mechanism and a control mechanism. When the engine of the vehicle is started, the electric motor generates rotational torque, which is transmitted to the ring gear on the flywheel of the engine through the drive gear of the transmission mechanism to drive the crankshaft of the engine to rotate. [0003] The control mechanism is used to control the on-off of the starter circuit, and to control the engagement and disengagement of the drive gear and the ring gear. At present, the widely used starter control mechanism is an electromagnetic switch. figure 1 A structural schematic diagram of an existing starter electromagnetic switch is shown. The electromagnetic switch mainly includes: an ...
