Abstract

The invention relates to a brake-tire-ground inner rotary drum type inertia brake test bench. The test bench comprises a ground foundation, a transmission system, a brake system, a control system, and a detection system. An industrial personal computer sends a speed command to a PLC, adjusts the speed of a frequency converter by controlling the frequency converter so as to adjust the speed of a vehicle, sets the moving inertia of the vehicle through an inertia adjusting device, sets the pressure exerted by a hydraulic cylinder on the ground, brakes the wheels of the moving vehicle through a brake actuator, and acquires the braking parameters of the vehicle through corresponding sensors. The technical problem that the existing test device cannot truly reflect the actual braking process of a vehicle is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle braking performance testing, in particular to an inner drum type inertial braking test bench including a brake-tyre-ground. Background technique [0002] Car braking performance is directly related to driving safety. It is of great significance to carry out brake-brake disc friction performance test, tire-ground friction performance test, and brake-tire-ground friction performance test to improve the braking performance of the whole vehicle. [0003] At present, the automobile braking test is mostly carried out by the roller reaction brake test bench or the automobile simulated brake test bench. The disadvantages of the existing technology will be described in detail below for the roller reaction brake test bench or the automobile simulated brake test bench. : [0004] When using the drum reaction brake test bench to test the car, the car wheel needs to be stopped on the drum, and the motor drive...
