As a key safety component of the automobile, the starting torque and drag torque of the brake assembly are key indicators for evaluating the efficiency, wear and overall performance of the transmission system, which directly affect the braking effect and safety of the automobile.
[0003] At present, the testing equipment on the market mainly focuses on the measurement of a single parameter, such as equipment specifically used for starting torque testing or systems dedicated to drag torque analysis; although these devices meet the basic needs of the industry to a certain extent, they have limitations such as single function, complex operation, and low testing efficiency. Specifically, starting torque detection and drag torque detection usually need to be performed separately. If the starting torque and drag torque detection values of the brake assembly need to be obtained, two devices must be used successively. This conversion process increases the loss of time and cost.

[0006] Furthermore, the torque detection module includes a torque loading component, a torque sensor and a torque output component; the torque loading component outputs a force to the torque output component, and the torque output component cooperates with the wheel hub bearing and / or the brake disc to drive the brake disc to rotate; the torque sensor is arranged between the torque loading component and the torque output component to detect the starting torque and the drag torque. Beneficial Effects
[0007] In the present invention, the brake assembly is lifted by a lifting module so that the wheel hub bearing of the brake assembly and the brake disc mounted on the wheel hub bearing are in an unrestricted rotation state; then, according to the detection requirements, the lifting contact block can be made to abut the movable part of the brake caliper to prevent the brake caliper from restricting the rotation of the brake disc, so as to perform the starting torque detection with the cooperation of the torque detection module; or, brake gas or brake fluid is provided to the brake caliper through an energy supply component to simulate the stress condition of the brake assembly in actual work, so as to perform the drag torque detection more accurately with the cooperation of the torque detection module; the device realizes the detection functions of both starting torque and drag torque through the cooperation of the torque detection module, the lifting module, the lifting mechanism and the energy supply component, thereby enhancing the versatility and practicality of the device and reducing the cost of enterprise detection; at the same time, there is no need to switch between the two devices, which greatly improves the detection efficiency.
