Abstract

The invention discloses an automobile electric mechanical booster performance test bench, which specifically comprises a test bench, the bottom of the test bench is fixedly connected with a support frame, and two sides of the inner wall of the test bench are fixedly connected with load devices; the power assisting mechanism is arranged in the center of the top of the test board, and the two ends of the power assisting mechanism are connected with the load device; one end of the connecting rotating shaft is connected with the power assisting mechanism, and the end, away from the power assisting mechanism, of the connecting rotating shaft is fixedly connected with a force applying device; the load device comprises a fixing seat, an adjusting hole is formed in the side face of the fixing seat, and the inner wall of one end of the adjusting hole is in threaded connection with a rotating screw rod. According to the performance test bench for the automobile electric mechanical booster, the power assisting effect of a power assisting mechanism under constant tension and gradually-increased tension can be conveniently detected, the load type can be changed, and the detection effect is good.

Description

technical field [0001] The invention relates to the technical field of booster performance testing, in particular to a performance testing bench for an automobile electric mechanical booster. Background technique [0002] The booster is a control device in the car with the help of compressed air, high-pressure oil, etc., to achieve the purpose of light use. Due to the limited manpower in the operation of large vehicles, there are many "assist" devices (scientific name "servo mechanism"), with power-assisted servo Take the brake system as an example. Its characteristic is that the control device of the servo system is directly controlled by the brake pedal mechanism, and its output force acts on the hydraulic master cylinder, which pressurizes the master cylinder oil together with the pedal force. The "pressurized" servo braking system is characterized by the brake pedal mechanism controlling the brake master cylinder, the hydraulic pressure output from the master cylinder is...
