Abstract

Disclosed is a solenoid valve for a brake system which has a simple structure, thereby being capable of achieving easy machining and assembly and reducing cost. The solenoid valve includes a sleeve fitted in a modulator block, an armature slidably disposed in the sleeve, a magnet core fitted in the sleeve at one side of the sleeve, to generate an electromagnetic force causing the armature to slide, a seat housing fitted in the sleeve at the other side of the sleeve and formed with oil inlet and outlet passages, and a valve seat disposed within the seat housing and formed with an orifice to be opened or closed in accordance with sliding of the armature. The armature includes a shim core disposed in the armature, to prevent generation of a residual electromagnetic force. The shim core is protruded toward the magnet core beyond the armature.

Description

technical field [0001] Embodiments of the present invention relate to a solenoid valve for a brake system, which has a simple structure, thereby enabling easy processing and assembly and cost reduction. Background technique [0002] Vehicles are basically provided with a braking system for braking. Recently, various braking systems for realizing stronger and stable braking force have been proposed. [0003] Examples of braking systems include anti-lock braking systems (ABS) that prevent wheel slip during braking, brake traction control systems (BTCS) that prevent sudden unintentional acceleration of the vehicle or slip of the drive wheels during sudden acceleration, and vehicle Dynamic Control System (VDCS), Vehicle Dynamic Control System (VDCS) is a combination of ABS and BTCS and maintains the running of the vehicle stably by controlling the brake oil pressure. [0004] In the case of ABS applied to a vehicle, a plurality of solenoid valves are provided. The solenoid va...
