Test stand for testing of electrical-power-assisted brake system

Abstract

The invention discloses a test stand for testing of an electrical-power-assisted brake system, so that problems that the result is not accurate, the input can not be adjusted based on drivers with different personalities, and the assisting rate of the test stand can not be adjusted because of offline simulation in the prior art are solved. The test stand comprises an electrical-power-assisted brake assembly, a hydraulic module, and a real-time platform. The electrical-power-assisted brake assembly consists of an electric cylinder input device and an electrical-power assisting device; the electric cylinder input device includes an input push rod; and the electrical-power assisting device includes a tooth bar. The hydraulic module consists of a reaction plate and braking main cylinders. The electric cylinder input device is inserted into a through hole with a small diameter of the tooth bar by the input push rod and is connected with the electrical-power assisting device. The reaction plate is installed in a through hole with a large diameter of the tooth bar; the right end surface of the reaction plate and the left end surface of the input push rod are in contact with and in connection with an annular end surface of a stepped through hole of the tooth bar; and the reaction plate is connected with the right end of an output push rod of the braking main cylinder at the left side. The electrical-power-assisted brake assembly and the hydraulic module are connected with a real-time platform by a line.

Description

technical field [0001] The invention relates to a test bench in the field of vehicle engineering, more precisely, the invention relates to a test bench for an electric power-assisted braking system. Background technique [0002] Since the electric power-assisted braking system cancels the vacuum booster commonly used in traditional vehicles, and can realize the decoupling of frictional braking force and regenerative braking force, and has a simple structure and convenient layout, it will become an inevitable direction for the development of braking systems. [0003] At present, the electric power-assisted braking system is still in the research stage, and the relevant technologies of major manufacturers are also in an undisclosed state. The testing methods for the electric power-assisted braking system of relevant research institutes are mainly offline simulation. Since this offline simulation is separated from the actual object and ignores many actual conditions of use, the...
