Abstract
Description
Technical Field
[0001] The utility model relates to an electric brake, in particular to an electric brake with reliable line connection. Background Art
[0002] Electric brake systems usually react faster than traditional hydraulic or pneumatic brake systems because electronic signals are transmitted extremely quickly with almost no delay. The electronic control system of the electric brake system allows for more precise distribution and management of braking force, so that the vehicle can achieve optimal braking performance under various driving conditions, which is particularly important for heavy vehicles and autonomous driving systems. The electric brake system can be closely integrated with other electronic systems (such as anti-lock braking system (ABS), electronic stability control system (ESC), etc.), thereby improving the overall safety and performance of the vehicle. The electric brake system eliminates the complex hydraulic circuits and mechanical components in the traditional brake system, which can reduce the total weight and maintenance requirements of the vehicle. Existing electric brake systems are connected to the control board through wires, which is not beautiful. At the same time, the electric brake system will generate a large reverse thrust and vibration when working, which can easily make the wire connection unreliable, and the wiring points will cause energy loss and overheating due to poor contact.
