Embodiment Construction

[0037] Some preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0038] figure 2 An electromagnetic switch for use in a vehicle starter according to an embodiment of the present invention is shown in . This electromagnetic switch comprises housing 2, and it has substantially cylindrical body and is located at body front end ( figure 2 The left end in the center, the end towards the vehicle engine side) the reduced diameter portion 2a.

[0039] In the rear portion of the body of the housing 2, a fixed iron core 4 is fixedly installed. The fixed core 4 includes a substantially disc-shaped large-diameter portion fixed in the body of the housing 2, a substantially cylindrical small-diameter portion protruding forward from the large-diameter portion, and a substantially frusto-conical portion protruding forward from the small-diameter portion. In addition, a guide through hole penetrating forward and backward in the ...

Abstract

A method of manufacturing an electromagnetic switch for a vehicle starter is disclosed, wherein a single push rod is moved backward until an initial electrical connection state is detected between two terminals via a contact bridge on the push rod; then, the push rod Further move backward for a reserved stroke; then, fix the movable iron core on the push rod while keeping the movable iron core pushed against the fixed iron core and process an engaging window for inserting the upper end of the shift fork into the front end of the push rod. An electromagnetic switch manufactured by the above method and a vehicle starter including the electromagnetic switch are also disclosed. The invention can improve the positioning accuracy of the driving gear.

Description

technical field [0001] The present invention relates to an electromagnetic switch used in a vehicle starter, a method of manufacturing the electromagnetic switch, and a vehicle starter including the electromagnetic switch. Background technique [0002] The starter of a motor vehicle is usually composed of a DC 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 el...
