Abstract

The invention relates to the field of automobile part detection devices, and provides a device for testing disc brake dragging torque and a heat energy recovery method. The device for testing the disc brake dragging torque comprises a base plate with a mounting seat and a support, a brake caliper locating seat connected with the base plate, a torque sensor connected with the support, a main shaft in pin joint with the mounting seat, a coupler, a brake test disc and a torque loading device, the brake test disc is connected with the other end of the main shaft, the torque loading device is connected with the other end of the torque sensor, and the two ends of the coupler are connected with one end of the torque sensor and one end of the main shaft respectively. The device for testing the disc brake dragging torque can provide accurate dragging torque testing parameters for improved design. A testing method meets test specifications, high-pressure compressed air is used for replacing hydraulic oil for testing, a brake lining is made to clamp or release the brake test disc fast, and cleanliness is achieved.

Description

technical field [0001] The invention relates to the field of vehicle component detection devices, in particular to a disc brake drag torque testing device and a testing method. Background technique [0002] In automobile design, the drag torque has become an important parameter index to reduce fuel consumption; the drag torque at the wheel accounts for a large proportion in the drag torque of the whole vehicle, and the drag torque at the wheel includes the friction of the hub bearing and the brake actuator The drag torque of the brake actuator and the reverse rotation of the drive shaft, etc., the drag torque of the brake actuator is very important to improve the design; the disc brake is a commonly used brake actuator; the structure of the disc brake can be obtained from the Chinese patent application number 201010623852.8 A disc brake disclosed by the invention is known; the disc brake includes a brake disc and a brake caliper that rotate together with the wheel, and the c...
