Electric magnet for actuating mechanism magnetic valve of electronic control system of automobile

Abstract

The invention provides an electric magnet for an actuating mechanism magnetic valve of an electronic control system of an automobile, relates to an electric magnet device of a magnetic valve, and aims at solving the problem that an existing electric magnet is not ideal in proportional characteristic, slow in dynamic response and high in manufacture cost. The electric magnet comprises an electromagnetic solenoid, a magnetic core, a pole shoe, a push rod and a guide sleeve. The guide sleeve is arranged in an inner hole of the electromagnetic solenoid, the magnetic core is arranged on one side close to the bottom end in the guide sleeve, and one end of the push rod is inserted into the magnetic core. A branch type structure is radially distributed in the middle of the push rod, a through hole is arranged on a push rod wall at the front end of the branch type structure, the rear end face of the branch type structure is tightly adhered to the front end face of the magnetic core, and the pole shoe comprises a large-diameter disc end and a small-diameter small cylindrical end, the front end of the push rod is inserted into the pole shoe, the small cylindrical end is arranged in the guidesleeve, an excircle of the small cylindrical end is matched with an inner hole of the guide sleeve, the top end of the small cylindrical end and the front end face of the magnetic core are separated through the branch type structure, and the front end face of the disc end is connected with a valve sleeve. The electric magnet is simple in structure, good in proportional characteristic, quick in dynamic response and low in manufacture cost.

Description

technical field [0001] The invention relates to an electromagnet device for a solenoid valve, in particular to an electromagnet for a solenoid valve of an actuator of an automobile electric control system. Background technique [0002] With the improvement of living standards and the development of automobile technology, people have higher and higher requirements for automobile handling, comfort, energy saving and environmental protection, which has prompted a large number of applications of automobile electronic control systems and rapid technological progress. Most of the execution needs solenoid valves to complete. The application of solenoid valves in automobiles will gradually increase. The execution accuracy and speed of solenoid valves are directly related to the performance of automobiles. Electromagnets are the core components of solenoid valves, which convert electrical signals into The kinetic energy that pushes the spool to work. In the high-precision proportiona...
