Embodiment Construction

[0044] Such as figure 1 As shown, the double-wedge type automotive electromechanical brake of the present invention includes a brake caliper body 21 and a brake disc 24. Friction plates are arranged on both sides of the brake disc 24, and the front friction plate 1 is fixedly connected through the front metal back plate 2. The front side floating caliper 3 and the rear friction plate 23 are fixedly connected to the piston 4 through the rear metal back plate 22, the piston 4 is connected to the brake caliper body 21 through a rectangular sealing ring 20, and the piston 4 can move axially along the brake caliper body 21;

[0045] The nut shaft 8 output by the motor 7 cooperates with the screw rod 12 to form a thread transmission, so as to realize the conversion of the rotary motion of the brake motor 7 into linear motion. Link mechanism is made up of upper connecting rod 10, connecting rod cover 11, lower connecting rod 13. The upper connecting rod 10 is connected with the brak...

Abstract

The invention discloses a double-wedge automotive electromechanical brake which comprises a brake caliper and a brake disc, wherein friction plates are arranged on two sides of the brake disc; the rear brake disc is fixedly connected with a piston; the piston can axially move along the brake caliper, and is connected with a left wedge through a clearance adjuster; a trapezoidal sliding block is mounted between the left wedge and a right wedge; balls are mounted on two sides of the trapezoidal sliding block; a nut shaft outputted from a motor is connected with a link mechanism, so that the rotary motion of the brake driving motor can be converted into linear motion; the lower connecting rod of the link mechanism is connected with the right wedge; and both the link mechanism and a wedge mechanism have a force increasing effect. The double-wedge automotive electromechanical brake provided by the invention has both the force increasing and automatic clearance adjusting functions; the clearances between the friction plates and the brake disc can be automatically adjusted, so as to guarantee the constancy of a brake response; and furthermore, the double-wedge automotive electromechanical brake is simple in structure, convenient to mount and lower in energy consumption.

Description

technical field [0001] The invention relates to an automobile braking system, in particular to an automobile electromechanical brake. Background technique [0002] With the development and transformation of modern automobile technology, people have higher and higher requirements for the safety, comfort and power of automobiles. As an important part of the automobile, the automobile braking system directly affects the safety performance of the automobile. Automobile braking technology is gradually developing towards electro-mechanical systems, and a more secure, efficient, energy-saving, and environmentally-friendly automotive electro-mechanical braking system has emerged. [0003] Automotive electromechanical brakes change the traditional hydraulic drive to electric drive, which makes up for the defects of hydraulic circuit leakage and slow response, and can implant a large number of electronic control system functions into it. [0004] However, the existing electronic mec...
