Problems solved by technology
Therefore, when the anti-lock braking system of the car is working, the driver can obviously feel the vibration of the pedal on the foot and hear some noise, which is likely to cause a certain psychological impact on the driver who takes the emergency brake. In a stable state, it is easy to operate incorrectly and cause traffic accidents

The invention provides an automobile anti-locking braking device which comprises a brake pedal, a brake main cylinder, an electromagnetic valve, an electronic controller, a liquid storage tank, an oil pump and a motor. The automobile anti-locking braking device is characterized in that the liquid storage tank is connected with a liquid outflow branch and a liquid inflow branch; the two branches are connected with a liquid inflow electromagnetic valve and a liquid outflow electromagnetic valve; the output end of the motor is connected with the liquid outflow branch; a shock absorber is arranged between the brake main cylinder and the brake pedal; a shock absorption pad is arranged on the brake pedal; and a frequency monitor is arranged between the brake main cylinder and the shock absorber. The two branches are connected to the liquid storage tank to replace an existing branch, so that braking liquid drainage is convenient; and the shock absorber is arranged, so that vibration of the brake pedal in the point-braking process is effectively reduced, the bad psychological suggestion effect on a driver is avoided, and the travel safety is guaranteed. The vibration frequency of the brake pedal in the point-braking process is collected through the frequency monitor and data are provided for re-improvement of a product. The automobile anti-locking braking device is improved on the basis of an existing braking device, and design is more user-friendly.
Description
technical field [0001] The invention belongs to the technical field of automobile braking, and in particular relates to an automobile anti-lock braking device. Background technique [0002] Automobile anti-lock braking system is a kind of automobile safety control system with the advantages of anti-skid and anti-lock. Its English abbreviation is ABS. The sensor installed on the wheel sends a signal that the wheel will be locked, and the controller instructs the regulator to reduce the oil pressure of the wheel brake cylinder, reduce the braking torque, and restore the original oil pressure after a certain period of time. This cycle is repeated continuously (up to 5~10 times per second), so that the wheels are always in a rotating state and have the maximum braking torque. For cars without ABS, if you press the brake pedal hard while driving, the wheel speed will drop rapidly. When the braking force exceeds the friction between the wheel and the ground, the wheel will be loc...
