Problems solved by technology

[0003] At present, the domestic railway freight car brake shoe clearance automatic test bench, in order to simulate the process of the change of the brake shoe clearance, usually adopts the situation of increasing or decreasing the gasket behind the brake adjuster screw to adjust the clearance, but the gasket is used. Adjusting the gap increases the length of the test bench, and the adjustment requires manual operation, which is error-prone and time-consuming

Abstract

The invention provides a brake shoes stack adjuster test table which is used for testing a brake shoes stack adjuster. The brake shoes stack adjuster test table comprises a clearance adjustment unit which comprises a lead screw component and a flexible member matched with the lead screw component. The flexible member is connected with the brake shoes stack adjuster. The length of the test table isreduced through arrangement of the lead screw component and the flexible member. The efficiency and the accuracy of clearance adjustment can be effectively enhanced through arrangement of the drivingmember and the transmission unit. Manual and automatic adjustment can be realized through arrangement of the second transmission shaft and the second gear.

Description

technical field [0001] The invention relates to the field of brake regulator test equipment, in particular to a brake regulator test bench. Background technique [0002] At present, most of the braking devices of railway freight cars adopt the tread braking method. During the braking process of railway freight cars, the friction between the brake shoe and the wheel tread will cause the gap between the brake shoe and the wheel to increase, making the brake cylinder Form growth, increase the compressed air volume in the brake cylinder, reduce the compressed air pressure in the brake cylinder, thereby reducing the braking force of the vehicle and increasing the braking distance. The two-way brake shoe clearance automatic adjuster for railway vehicles (hereinafter referred to as "brake adjuster") is an important part of the foundation braking device of railway freight cars. When the gap between the brake shoe and the wheel increases or decreases, the brake adjuster can Automati...
