Embodiment Construction

[0014] exist figure 1 , 2 In the shown embodiment, a kind of two-way detection valve comprises the loam cake (1) that is provided with the air inlet (8) that ASR system is used, is provided with the air inlet (9) that ABS system is used, and connects brake air chamber The valve body (4) of the air outlet (10), the upper cover (1) is tightly connected with the valve body (4) through bolts (2) to form a three-way connection, and it is characterized in that: a two-way sliding valve is arranged in the valve body (4). The two-way valve (7), the two-way valve (7) seals the air inlet (8) for ASR in the normal service braking process, and seals the air inlet (9) for ABS in the starting / acceleration process.

[0015] In order to make the two-way valve (7) work reliably in the valve body, and to make the upper cover (1) and the valve body (4) accurately positioned, a guide sleeve (6) can also be arranged in the valve body (4), and the two-way valve (7) Slide inside the guide sleeve (6...

Abstract

A bidirectional detecting valve for the braking system of car is composed of a valve body with a top cover of the air inlet for ASR system, an air inlet for ABS system and an air outlet communicated to the braking air chamber, a bidirectional valve gate sliding bidirectionally in valve body for controlling the air inlet for ASR system and the air inlet for ABS system, and a guide sleeve in which said bidirectional valve gate can slide.

Description

technical field [0001] The invention relates to an automobile brake system component, in particular to a bidirectional detection valve used in an automobile anti-lock brake system (ABS) or an actuation anti-skid system (ASR). Background technique [0002] During the braking process of the traditional automobile braking system, the situation of wheel locking often occurs. When the front wheels are locked, the wheels of the car will lose the ability to turn; when the rear wheels are locked, the car will skid and flick; when all the wheels are locked, the steering force and lateral force of the car are close to zero. The car completely loses handling and directional stability. For a full trailer, locking the wheels will cause the trailer to separate from the front of the vehicle; for a semi-trailer, locking the wheels will cause the hinge to fold in half. These situations are all likely to cause major traffic accidents. Introducing an anti-lock braking system (abbreviated as...
