Problems solved by technology
[0005] Long-term use of the handbrake will cause plastic deformation of the steel wire. Since this deformation is irreversible, long-term use will reduce the braking efficiency of the handbrake and increase the braking stroke of the handbrake.

The invention relates to the technical field of hand brake detection, in particular to a fatigue strength test bench for the hand brake of an automobile, which comprises a workbench, a pulling deviceused for pulling the hand brake handle, a base device used for installing the hand brake assembly, a pulley device and a load bearing device, the base device is arranged on side of the top of the workbench, the load bearing device is arranged on the other side of the top of the workbench, the pulley device is arranged at the top end of the workbench and the pulley device is arranged between the base device and the load bearing device, the pulling device is arranged at the top end of the workbench and is arranged between the base device and the pulley device; the operation of a hand is simulated by pressing the button of the hand break through a pressing device, so that a pulling cylinder pulls the hand break, the drawing wire and spring of the hand brake are tested under the pulling condition for multiple times; by arranging a plane turbine spring to carry out load bearing on the drawing wire and through the arrangements for adjusting the first telescopic rod and the second telescopicrod, the drawing wire is more effectively detected.
Description
technical field [0001] The invention relates to the technical field of handbrake detection, in particular to an automobile brake handbrake fatigue strength testing platform. Background technique [0002] The car hand brake device is an indispensable auxiliary device on the car. The types of hand brakes can be divided into mechanical hand brakes and electronic hand brakes. The main advantages of mechanical hand brakes are low cost, flexible application, and high reliability. The main advantages of electronic hand brakes are The appearance is simple and beautiful, and it is easy to use. The electronic handbrake is a common configuration on mid-to-high-end cars. Judging from the current automobiles, due to cost constraints, most low-end and mid-end automobiles still use mechanical handbrake devices. The handbrake device is mainly composed of handles, steel wires, return springs and other components. [0003] The professional name of the handbrake is the auxiliary brake, which...
