Abstract

The invention provides a brake clamp testbed. The brake clamp testbed comprises a support capable of fixing a brake clamp, and a rotary disc unit capable of linearly reciprocating in the direction vertical to the support. Two limiting units capable of hoisting the brake clamp are installed on the top of the support, first through holes capable of being connected with the two ends, in the clamping direction, of the brake clamp in a sleeving mode are formed in the limiting units, and the support is provided with a first driving unit capable of driving the brake clamp to rotate around the axes of the first through holes. The rotary disc unit comprises a rotary disc with the two side faces capable of being clamped by the brake clamp at the same time, and a second sliding base capable of supporting the two sides of the rotary disc. The second sliding base is connected with a second driving unit capable of driving the second sliding base to linearly move. The test result is accurate, and the assembly efficiency of the brake clamp is high.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle brake test equipment, in particular to a brake caliper test bench. Background technique [0002] The brake caliper unit includes a brake caliper and a brake disc, which are generally used in high-speed railway locomotives, urban rail vehicles, ordinary railway passenger cars, high-speed EMUs and other rail vehicles that use disc brakes to achieve Common braking (including pneumatic braking and hydraulic braking) and parking braking of rail rolling stock. The above-mentioned disc brake is to install the brake disc on the axle or on the side of the wheel web, and use the two brake pads of the brake caliper made of synthetic materials to press the side of the brake disc to generate braking force through friction. to stop the train. [0003] The brake caliper test bench is used to test the performance of the brake caliper unit after leaving the factory or after maintenance (including brake pres...
