Problems solved by technology

During the above-mentioned braking process, due to the longer time for the motor to transmit the torque to generate the braking clamping force, the real-time performance of the braking effect is poor, which cannot meet the requirements for the braking response time of the vehicle during emergency braking.
In addition, the braking clamping force generated by the motor transmission torque is small, and it cannot be braked under a large braking clamping force, and the braking effect is poor.

Abstract

The invention provides an electric brake, comprising a shell (17), a brake disc (15), a brake block and a power mechanism which can push the brake block to move forwards so as to clamp the brake disc, wherein the power mechanism comprises a motor (1) and a movement mechanism which is connected with an output end of the motor, the movement mechanism can transform the rotating movement of the motor into straight line movement, and the brake block is arranged in front of the movement mechanism. The electric brake is characterized in that: the power mechanism also comprises a torque amplification mechanism which is arranged between the motor and the movement mechanism, an input end of the torque amplification mechanism is connected with the output end of the motor, and an output end of the torque amplification mechanism is connected with the movement mechanism. The electric brake is compact in structure, is short in brake response time and can generate greater brake clamping force.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to an electric brake and an automobile using the electric brake. Background technique [0002] At present, most vehicle braking systems at home and abroad still use hydraulic braking systems based on hydraulically controlled mechanical pressure to achieve braking purposes. The traditional hydraulic braking system controls the braking force through solenoid valves (including booster valves, pressure relief valves, etc.). The above-mentioned hydraulic braking system has defects such as complex structure, inconvenient installation, high price, failure to monitor faults in real time, and slow braking response. [0003] The new electromechanical braking system has just started. It simulates the pedal force feeling through the pedal feeling simulator, collects the pedal displacement through the pedal displacement sensor, and obtains the output braking torque ...
