Abstract

The invention provides a rear axle driving double-loop control braking system and a vehicle. The braking system comprises a braking main valve, double air cylinders, double relay valves, a spring double-cavity braking air chamber and an anti-lock device. Wherein the rear axle driving double-loop brake system adopts double air cylinders, double relay valves and a spring double-cavity brake chamber, the double air cylinders are respectively connected with air inlets of the double relay valves, air outlets at one ends of the two relay valves are connected in series, air outlets at the other ends of the two relay valves are respectively connected with anti-lock devices at two sides, the spring double-cavity brake chamber is controlled by the anti-lock devices, and the anti-lock devices are connected with the brake chamber. And control ports of the double relay valves are connected by a three-way connector body through a gas circuit and are controlled by a brake main valve. Due to the fact that the two air cylinders supply air to the two relay valves respectively, the air inlet efficiency is improved, the air outlets of the two relay valves are connected in series for ventilation, brake air pressure on the two sides is balanced, the risk of left and right brake force deviation is reduced, the response time is shortened, and the brake performance is improved.

Description

technical field [0001] The invention relates to the field of vehicle braking, in particular to a rear-axle driving dual-loop control braking system and a vehicle. Background technique [0002] The response time is clearly specified in GB12676-2014 "Technical Requirements and Test Methods for Braking Systems of Commercial Vehicles and Trailers". For vehicles using pneumatic brakes, during emergency braking, the control device is activated from the start to the most unfavorable moment. The time it takes for the braking force on the axle to reach the corresponding specified braking effect should not exceed 0.6s. For heavy-duty vehicles that need to adapt to different working conditions, the requirements for braking response time are more stringent. [0003] The name of the utility model is full-dual-circuit braking system, and the patent number is CN201800704U, which provides a full-dual-circuit braking system. The air inlet and outlet make the car more stable, but the chargi...
