Abstract

The invention discloses an air pressure anti-lock braking system (ABS) regulating valve. The air pressure ABS regulating valve comprises an outer shell, wherein an inlet valve seat and an exhaust valve seat are arranged in the outer shell; an inlet channel is positioned on the inlet valve seat; an outlet channel and a pressure reducing exhaust channel are arranged on the exhaust valve seat; a valve core assembly is installed between the inlet valve seat and the exhaust valve seat; the inlet channel of the inlet valve seat is communicated with the outlet channel of the exhaust valve seat by a gas circuit of the valve core assembly; the valve core assembly comprises a valve core body and an electromagnetic coil sleeved to the valve core body; the electromagnetic coil is provided with two working currents; when the small current is charged to the electromagnetic coil, induction electromagnetic force is generated by the whole outer circumferential surface of the valve core and the gas flow in the inlet channel of the inlet valve seat is reduced till the inlet channel is closed; and when the large current is charged to the electromagnetic coil, the valve core body in the valve core assembly is moved towards the inlet valve seat continuously, and a cylindrical pin on the valve core body compresses an external spring so that a gap between the valve core body and the inlet valve seat is zero, an internal spring is recovered to an initial compression state to open a pressure relief valve port, and the outlet channel is communicated with the pressure reducing exhaust channel, thereby realizing the pressure reduction.

Description

technical field [0001] The invention relates to a regulating valve, in particular to a pneumatic ABS regulating valve used for braking of medium and large passenger cars. Background technique [0002] The pneumatic ABS regulating valve is suitable for medium and large passenger cars. The overall structure of the existing pneumatic ABS regulating valve mainly adopts segmented valve cores, and each valve core is equipped with a special electromagnetic coil to control the movement of the valve core in segments. [0003] Such as figure 1 Schematic diagram of the working principle of the existing air pressure ABS regulating valve. A normally open solenoid valve a is arranged on the intake air path, and a vent branch is also provided on the intake air path between the normally open solenoid valve a and the brake caliper c. The vent branch passes through The normally closed solenoid valve b communicates with the outside atmosphere. The normally open solenoid valve a and the norma...
