Problems solved by technology

These can not more realistically simulate the contact situation between the passenger car and the road surface when braking. In order to solve this problem, the present invention proposes a new method for simulating the contact situation between the wheels and the road surface. The equipment is simple, the capital investment is less, and the passenger car can be more realistically simulated. How ABS works when braking in various road conditions

Abstract

The invention provides a passenger car ABS (anti-lock braking system) braking bench and belongs to the field of detection of car performance. The passenger car ABS braking bench is characterized in that a drum frame (4) can move in the direction of a rack-type sliding rail (5); wheels (19) drive a drum (2) through friction; a water sprayer (6) and a feeding mechanism (18) are installed on the drum frame (4); a sandstone recycling device (16) is installed at the lower end of the drum frame (4); a conveying device (17) is installed between the feeding mechanism (18) and the sandstone recycling device (16); the conveying device is driven by a motor; a driving belt is provided with strip-shaped rubber bulges. By adopting the passenger car ABS braking bench provided by the invention, the friction coefficient of a pavement can be simulated more vividly through a water spraying system and a sandstone system.

Description

technical field [0001] The invention relates to an ABS braking test bench for passenger cars, which belongs to the field of vehicle performance detection. Background technique [0002] With the continuous development of the automobile industry, people have higher and higher requirements for the performance of automobiles. People no longer only pursue the power and off-road performance of automobiles, but also have higher and higher requirements for the comfort and safety of automobiles. The wheels of a car without an ABS anti-lock braking system will quickly lock up when braking, which will have a great impact on the handling stability of the car and cause traffic safety accidents. A car equipped with an ABS anti-lock braking system can prevent the car from losing its steering ability and running off track when braking, and ensure driving safety. As a large-scale passenger vehicle, the performance of ABS is very important, and it is imperative to test its ABS performance. ...
