Abstract

The invention discloses an automobile electromechanical brake with a gap adjusting function. The automobile electromechanical brake comprises a floating caliper body and a brake disc, wherein friction plates are arranged at two sides of the brake disc, a rear friction plate is fixedly connected with a piston, and the piston can perform axial movement along the floating caliper body; a motor stator is mounted on the floating caliper body, a motor rotor is connected with a center gear of a planet gear speed reducer, a planet carrier is fixedly connected with a lead screw, and the lead screw is in threaded transmission with a threaded hole of a spline shaft, so that rotary motion of a brake motor is converted into linear motion; and an adjusting screw rod is connected with the spline shaft by a thrust bearing, and a gap adjusting mechanism is arranged between the adjusting screw rod and an adjusting support frame and can automatically adjust the gap between the brake disc and the friction plates so as to ensure the constancy of automobile braking response speeds and to further guarantee the braking performance. The automobile electromechanical brake is excellent in braking performance, deliberate in structure, small in mounting space and easy to maintain.

Description

technical field [0001] The invention relates to a new type of automobile brake system, in particular to an automobile electromechanical brake with gap adjustment function. Background technique [0002] With the development and transformation of modern automobile technology, electric vehicles are developing rapidly. As an important part of the automobile, the automobile braking system directly affects the safety performance of the automobile. Modern automobile brake technology is also developing towards electric power, and automobile brake-by-wire technology, especially automobile electromechanical brake technology, is becoming the research focus of major automobile manufacturers. [0003] Compared with the traditional hydraulic braking system, the automotive electromechanical braking system has many advantages, such as no hydraulic oil, environmental friendliness, fast control response, easy integration into ABS (anti-lock braking system), TCS (traction control system), ESP...
