Abstract
There is disclosed a solenoid-supporting device for an antilock brake system by which the vibration and noise created from solenoid valves are attenuated and the heat generated from the solenoid valves are effectively radiated. The solenoid-supporting device comprises: a base plate contacting the bottom surface of a modulator block; a plurality of penetration holes formed at the base plate in order that valve bodies pass through the penetration holes and are combined with solenoids; and a plurality of elastic members which are made by extending from the base plate around the respective penetration holes in order to urge the solenoids to the ECU housing.
Claims4
In an antilock brake system which comprises:
- brakes mounted on each wheel of a vehicle;
- a master cylinder for transmitting hydraulic oil to the brakes to generate a braking power;
- a plurality of solenoid valves for controlling the flow of the hydraulic oil supplied from the master cylinder, each of which comprises a solenoid for creating an electric field and a valve body for opening or closing an oil passage formed therein by interacting with the electric field created by the solenoid;
- an ECU for controlling the solenoid valves;
- a modulator block in which the valve bodies are mounted;
- an ECU housing joined to the bottom of the modulator block, in which the solenoids are mounted;
- and a solenoid-supporting device provided between the modulator block and the ECU housing for supporting the solenoids, the improvement wherein the solenoid-supporting device comprises:
- a base metal plate contacting the bottom surface of the modulator block;
- a plurality of penetration holes formed at the base metal plate in order that the valve bodies pass through the penetration holes and are combined with the solenoids;
- and
- a plurality of elastic members which are formed by extending from the base metal plate around the respective penetration holes, the elastic members urging the solenoids to the ECU housing while dissipating heat.
