Background
The manual brake is called as an auxiliary brake in the profession, and is different from the principle of the brake, and a steel wire pull wire is connected to a rear brake shoe to brake a vehicle. The long-term use of the hand brake can cause the steel wire to generate plastic deformation, and because the deformation is unrecoverable, the long-term use can reduce the effectiveness, and the stroke of the hand brake can be increased. A return spring is also matched with the hand brake. When the hand brake is pulled up, the spring is stretched, and when the hand brake is released, the spring returns to the original length. When the hand brake is used for a long time, the spring can also generate corresponding deformation. The existing automobile hand brake switch is used for detecting the detection device for the service life of the spring, is generally high in cost, multiple in parts and poor in detection effect. In order to solve the problem, the utility model provides a service life detection device for an automobile hand brake switch.
