Shock-free disc brake

Abstract

The invention relates to a shock-free disc brake for a passenger car. The biggest difference between the shock-free disc brake and an existing caliper disc brake is in structural mechanical characteristics, the shock-free disc brake adopts couple braking, and the existing caliper disc brake adopts torque braking, so that the shock-free disc brake always has tangential force, and the specific structure is as follows: two to four sets of brake pads are completely symmetrically and uniformly distributed on the shock-free disc brake by taking a brake disc rotation center as a center; the caliper disc brake is only provided with a set of brake pads which are arranged on one side of the rotation center of the brake disc in an offset mode, and the use effects are shown as follows: even if parts such as a pin hole are large in clearance and low in precision, the vibration-free disc brake is still free of vibration and noise during braking all the time, and after the caliper disc brake is used for a period of time (or low in precision), due to the fact that the clearance of the parts is increased, the brake pad cannot be damaged. Vibration and noise can be generated during braking. The problem is not solved in the world so far, the root of the problem is torque braking instead of couple braking on the aspect of structural mechanical characteristics, and a hard knot must be formed.

Description

Technical Field

[0001] The invention relates to a vibration-free disc brake for a passenger car. Background Art

[0002] So far, all passenger cars in the world that use disc brakes are caliper-type brake pads with offsets. As a result, after a period of use (low precision), the caliper disc brake will generate vibration and noise when braking due to the increase in the gap between parts. This is a global unsolved problem. Nowadays, people have higher and higher requirements for the quality of life. Although the vibration and noise generated during braking will not cause traffic accidents, the riding experience and the high-end luxury of the vehicle will be discounted, which is undoubtedly unpleasant for vehicle manufacturers and passengers.

[0003] The only way to solve this global unresolved problem is to seek a breakthrough in theory. Therefore, our shock-free disc brake abandons torque braking and changes to couple braking, which easily solves the problem. Summary of the invention

[0004] In view of the above problems, the shockless disc brake of the present invention has two to four sets of brake pads evenly distributed in a completely symmetrical manner around the rotation center of the brake disc, forming a couple braking. Even if the gap between parts such as the pin holes is large and the precision is low, the shockless disc brake is still free of vibration and noise during braking, thereby enhancing the high-end luxury of the vehicle and improving the ride comfort.

[0016] The auxiliary bracket 1, a pressure plate 2, bolts 3, brake pads 4, brake discs 5, pistons 6, oil seals 7, main brackets 8 and other parts are composed. DETAILED DESCRIPTION

[0017] The present invention relates to a vibration-free disc brake, the structural shape and composition relationship of which are the implementation mode of the present invention.

[0018] A fan-shaped dovetail groove is opened at the corresponding position of the auxiliary bracket 1, and the brake pad 4 is inserted. They are fastened to the auxiliary bracket 1 with a pressure plate 2 and bolts 3. One end of the piston 6 is placed in the corresponding oil cylinder, and the other end is provided with a fan-shaped dovetail groove for installing the brake pad. The brake pad 4 is inserted and fastened to the piston 6 with a pressure plate 2 and bolts 3. The piston 6 has only one degree of freedom and moves along its own axial direction. Two to four sets of brake pads are evenly distributed completely symmetrically with the rotation center of the brake disc, and then the brake disc 5 is placed in the middle. The main bracket 8 and the auxiliary bracket 1 are as shown in the attached figure Fig. 9 As shown, they are fastened together with bolts.

Claims
