Abstract

The invention relates to an electromagnetic valve used for an EBS braking system, and belongs to the field of vehicle braking control devices. The electromagnetic valve solves the problem that the vehicle braking effect is poor. The electromagnetic valve comprises a valve body. A sleeve and an electromagnetic coil arranged on the sleeve in a sleeving mode are arranged in the valve body. A movable iron core assembly, a fixed iron core assembly and a reset spring located between the movable iron core assembly and the fixed iron core assembly are arranged in the sleeve. An assembly opening is formed in one end of the sleeve, and a positioning turned edge is arranged at the other end of the sleeve. The movable iron core assembly and the fixed iron core assembly are arranged in the sleeve through the assembly opening. The movable iron core assembly is located between the fixed iron core assembly and the positioning turned edge. The fixed iron core assembly is fixed to the inner wall of the sleeve. The movable iron core assembly moves between the fixed iron core assembly and the positioning turned edge so that the electromagnetic valve can be opened and closed.

Description

technical field [0001] The invention relates to an electromagnetic valve used in an EBS braking system, belonging to the field of vehicle braking control devices. Background technique [0002] The existing vehicle braking control device is provided with an actuator, which is controlled by the EBS braking system. The central control unit on the EBS braking system sends out an electric signal to adjust the brake air pressure of the vehicle through the actuator. The solenoid valve is the core component of the actuator. The existing solenoid valve has a split structure. The solenoid valve of this structure has poor braking effect, short service life of the brake pads, and increased safe driving distance of the vehicle. Contents of the invention [0003] The problem to be solved by the present invention is to provide a solenoid valve for an EBS braking system, which solves the problem of poor braking effect. [0004] In order to solve the above problems, the present invention ...
