Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brake testing equipment, in particular to a brake torque testing device. Background Art
[0002] The static torque test of brakes is a key step in evaluating brake performance. The static torque test is designed to measure the torque that the brake can withstand when stationary in order to evaluate its structural strength, friction performance, and overall reliability. This is crucial to ensuring that the brake can operate stably and effectively in actual applications. The static torque test is based on the product relationship between torque and lever arm, that is, T = F × L (T is torque, F is force, and L is lever arm). During the test, the performance of the brake is evaluated by applying a continuously increasing force to the brake and measuring the torque value generated by this force.
[0003] Existing brake torque testing methods typically use a torque wrench to steadily increase torque. When the brake or related fasteners produce a slight rotation, the torque value is recorded. Although this method is simple, due to differences in operator skill, the measured torque value is often too high, resulting in poor accuracy. Furthermore, human resources are limited. Therefore, a device that facilitates high-precision brake torque testing was designed. Utility Model Content

Figures 1-4 As shown, this embodiment is a brake torque testing device, comprising a support base 1, and a core shaft 2 passing through the support base 1 and rotatably connected thereto; one end of the core shaft 2 is connected to a brake body 6, and the other end thereof is connected to a rocker 3; a lifter 5 is mounted on the end of the rocker 3 away from the core shaft 2, and a sensor 4 is provided between the lifter 5 and the rocker 3; specifically, by mounting the brake body 6 to be tested on the support base 1, the core shaft 2 is fitted into the inner hole of the brake body 6, the brake body 6 is in a braking state, and the length of the rocker 3 is adjusted according to the brake The static torque of the main body 6 is adjusted, the jack 5 lifts the rocker arm 3 and obtains the pressure value of the sensor 4. Combined with the length of the rocker arm 3, the static torque value of the brake main body 6 can be obtained. The data accuracy is relatively high, and the jack 5 uses a jack or other lifting tools to achieve large torque testing. The jack 5 provides a continuously increasing force. The force is monitored by the sensor 4 and a force-time curve is drawn by the test system. The principle that the torque will decrease when the brake slips is used, and the curve will have a peak. The peak is used to judge the static torque by sliding.
