Device and method for testing liquid consumption of hydraulic brake caliper comprehensive performance test bed

Abstract

The invention discloses a device and method for testing the liquid consumption of a hydraulic brake caliper comprehensive performance test bed. Rotational motion can be converted into linear motion by means of the device for testing the liquid consumption of the hydraulic brake caliper comprehensive performance test bed through a ball screw, the linear feeding amount is transmitted to a push rod of a clutch master cylinder, a testing assembly is simple in structure and is practical, and a servo motor which is connected with a speed reducer is connected with the ball screw simply and reliably through a coupler. A testing loading mechanism is simple in structure and high in precision and is provided with a zero setting device. A fixing assembly of the device for testing the liquid consumption is fast to use, accurate, simple in structure, accurate in positioning and convenient to position. According to the method for testing the liquid consumption of the hydraulic brake caliper comprehensive performance test bed, testing can be achieved fast, and the testing accuracy is high. By the adoption of the device for testing the liquid consumption of the hydraulic brake caliper comprehensive performance test bed, accurate testing data of liquid consumption can be provided for improved design. The method accords with the testing standard. By the adoption of the device for testing the liquid consumption of the hydraulic brake caliper comprehensive performance test bed, liquid consumption of a brake caliper can be tested highly efficiently, and the testing precision is high.

Description

[0001] technical field [0002] The invention relates to the field of auto parts testing, in particular, the invention relates to a fluid consumption test device and a test method of a hydraulic brake caliper comprehensive performance test bench. [0003] Background technique [0004] Automobile braking performance is directly related to traffic safety. Major traffic accidents are often related to excessive braking distance and sideslip during emergency braking. Therefore, braking performance is an important guarantee for automobile safety. The brake caliper is an important part of the disc brake. The structure of the disc brake can be obtained from a disc brake disclosed in the invention of Chinese patent application No. 201010623852.8; the main components of the disc brake include the brake disc, cylinder , brake caliper, oil pipe, etc.; the structure of the brake caliper assembly can be understood from a brake caliper assembly disclosed in the invention of Chinese patent...
