Air pressure brake system's comprehensive performance simulating apparatus and method

Abstract

The invention discloses an air pressure brake system's comprehensive performance simulating apparatus and method. The apparatus is capable of achieving air pressure brake simulation not only for buss, trucks, semi-trailers, passenger cars and incomplete passenger vehicles but also for the brake of long wheelbase cars, multi-axis and towing semi-trailers, trailers and other car systems. The apparatus can simulate six axles at the same time. The apparatus comprises a pneumatic brake system console, six movable axles with a brake air chamber and load simulator, a disc load simulation system, an air push chamber simulation system, and other brake actuators. The pneumatic brake system adopts the disc load simulation for passenger cars, trucks, semi-trailers, and incomplete passenger vehicles and the air push chamber simulation for incomplete freight vehicle. The apparatus provides two control modes for the trampling simulation of an air pneumatic brake with one directly simulating the stepping of an actual vehicle, and the other stepping mode precisely controlled through an electric cylinder.

Description

technical field [0001] The invention relates to a performance simulation test device for an air pressure braking system, in particular to a comprehensive performance simulation device and a simulation method for an air pressure braking system. Background technique [0002] Pneumatic braking uses compressed gas as the braking source, and the brake pedal controls compressed air to enter the wheel brakes, so the biggest advantage of pneumatic braking is that it is easy to operate and provides large braking torque. It has unique advantages to realize asynchronous distributed braking for multi-axis, multi-axle and towing semi-trailer, trailer, etc. [0003] The pneumatic brake transmission device drives the air compressor to work with the power of the engine, and then converts the pressure of the compressed air into a mechanical thrust to brake the wheels. The driver only needs to control the stroke of the pedal to release different amounts of compressed air according to differe...

AI Technical Summary

Problems solved by technology

In the air braking process, the most important thing is compressed air. When there is no compressed air or the air pressure is too low, effective braking will not occur, making it difficult to ensure the reliability and safety of the braking system.

Moreover, the simulation of the individual performance of each component of the air brake system cannot prove that the entire air brake system can have sufficient reliability, and currently there is a lack of a comprehensive simulation device to evaluate the reliability and safety of the air brake system. simulation test
