A fixed caliper disc type electronic parking brake and automobile

Abstract

The invention discloses a fixed-caliper disc type electronic parking brake, which comprises a sequentially connected driving motor, a first deceleration mechanism, a second deceleration mechanism and a third deceleration mechanism, and the output torque of the driving motor is amplified after three stages of deceleration. The three-stage reduction mechanism is connected with a motion conversion mechanism, which converts the circular motion output by the third reduction mechanism into a linear motion. The motion conversion mechanism is provided with two sets, and each set of motion conversion mechanism is connected to a friction plate. Driven by the motion conversion mechanism, the sheet can move linearly to clamp the brake disc. The fixed caliper disc type electronic parking brake provided by the present invention has the advantages of simple structure, small space occupation, easy arrangement, short braking response time, little physical exertion for the driver, simple start-up operation on a slope, and high safety. The invention also discloses an automobile, a motorcycle, a modified car and a racing car with an internal combustion engine as a power source.

Description

technical field [0001] The invention relates to an electronic parking brake applied to a passenger car, more precisely, the invention relates to an electronic parking brake applied to a fixed caliper disc brake. Background technique [0002] At present, ordinary passenger cars mostly use floating caliper disc brakes, while sports cars or racing cars mostly use multi-cylinder fixed caliper disc brakes. The existing car manual parking brake device mainly controls mechanical cables to drag brake levers and other mechanisms through the parking brake handle to make the brake shoes press the brake drum to realize the parking brake (drum brake), or tow The ball wedge mechanism (BIR) makes the brake pads on both sides of the brake disc clamp the brake disc to realize parking brake (floating caliper disc brake). With the improvement of the electronic level of automobiles, there are more and more comfort and convenience equipments in automobiles. Traditional manual parking brakes ar...

AI Technical Summary

Problems solved by technology

However, the multi-cylinder fixed-caliper disc brakes that are applied to sports cars and sports cars with faster response, greater braking force and more uniformity are difficult to upgrade to electronic parking brakes due to structural reasons, so such models are still common Use traditional human braking device, which cannot match its high car price and luxury configuration

The current solution generally uses an additional floating caliper disc electronic parking brake on the rear wheel to achieve automatic parking and assisted start. This solution has a low degree of integration, takes up a lot of space, and is difficult to arrange.
