Description

Technical Field

[0001] The utility model relates to the field of disc brakes, in particular to a combined noise-free electric vehicle disc brake. Background Art

[0002] A disc brake consists of a brake disc connected to a wheel and brake calipers at the edge of the disc. When braking, high-pressure brake fluid pushes the brake pads to clamp the brake disc, thereby generating a braking effect.

[0003] It is known that the Chinese utility model patent CN220037302U discloses a combined electric vehicle disc brake structure, including a brake piston housing. On one side of the inner wall of the brake piston housing, there is a hydraulic fixed block fixedly connected. On one side of the hydraulic fixed block, there is a hydraulic brake rod fixedly connected. On the top of one side of the hydraulic brake rod, there is a spring. On the bottom surface of one side of the hydraulic rod sleeve, there is a sound-absorbing sheet fixedly connected. On the outer wall of the sound-absorbing sheet, there is a steel back fixedly connected. On the other side of the outer wall of the steel back, there is an alarm sheet fixedly connected. On the other side of the outer wall of the alarm sheet, there is a friction layer. In this utility model, by driving the hydraulic brake rod, the friction material is squeezed inward to achieve the effect of decelerating and stopping the wheel. When the friction layer rubs against the first and second disc brake discs, the friction layer will gradually become thinner, exposing the alarm sheet. Through further friction, the brake disc will make a sound, which can remind the vehicle owner to replace the brake pads in time.

[0004] However, in the implementation of the related technology, it is found that the above scheme has the following problems: the noise reduction effect is poor, and it cannot better absorb and reduce noise. Although the sound-absorbing sheet can reduce some braking noise to a certain extent, there is still serious noise in many cases, which will affect the driving experience of electric vehicles or motorcycles. Therefore, a combined noise-free electric vehicle disc brake is needed. Summary of the Utility Model

[0005] To solve the above problems, the utility model proposes a combined noise-free electric vehicle disc brake to solve the problems existing in the above prior art.

[0006] To achieve the above object, the combined noise-free electric vehicle disc brake provided by the utility model includes a disc brake disc, a caliper, a piston and an oil pipeline. The caliper is arranged on the outer side of the disc brake disc. The piston is inserted into the inner side of the caliper. The oil pipeline is fixedly installed on one side of the caliper. One end of the oil pipeline away from the caliper is fixedly connected with a high-pressure hose. A first fixing plate is fixedly installed on one side of the piston. A second fixing plate is fixedly installed on one side of the inner wall of the caliper. Brake pads are arranged on one side of both the first fixing plate and the second fixing plate. Connecting components are arranged on one side of both the two brake pads. One of the brake pads is fixedly connected to the first fixing plate through the connecting component arranged thereon, and the other brake pad is fixedly connected to the second fixing plate through the connecting component arranged thereon. A sound-absorbing cotton is fixedly installed on the outer surface of the caliper. A glass wool is fixedly installed on the outer surface of the sound-absorbing cotton. A mineral wool is fixedly installed on the outer side wall of the glass wool. A sound insulation board is fixedly installed on the outer surface of the mineral wool.

[0007] Furthermore, the connecting component includes a clamping plate fixedly installed on one side of the brake pad. Clamping grooves are respectively formed on one side of both the first fixing plate and the second fixing plate. The clamping plate is inserted into the clamping groove. Locking mechanisms are arranged on both the first fixing plate and the second fixing plate. The clamping plate is fixedly installed inside the clamping groove through the locking mechanism.

[0008] Furthermore, the locking mechanism includes a first screw hole formed on the clamping plate. Second screw holes are respectively formed on the outer side walls of both the first fixing plate and the second fixing plate. A screw is in threaded connection in the communicating first screw hole and second screw hole. The clamping plate is fixed inside the clamping groove through the first screw hole, the second screw hole and with the cooperation of the screw.

[0009] Furthermore, sound damping sheets are fixedly installed on one side of the inner walls of both the first fixing plate and the second fixing plate. Both the two sound damping sheets are located inside the clamping groove.

[0010] Furthermore, the sound damping sheet is made of rubber.

[0011] Compared with the prior art, the beneficial effect of the utility model lies in that:

[0012] Through the sound-absorbing cotton, glass wool, mineral wool and sound insulation board wrapped outside the caliper, the noise can be weakened multiple times and effectively, so that the noise reduction effect of the device is good, and the noise can be better absorbed and reduced, thereby preventing the noise from being too large and affecting the driving experience of electric vehicles or motorcycles.

[0013] The clamping plate is manually inserted into the clamping groove, and the locking mechanism is tightened, so that the worn brake pads on the first fixing plate and the second fixing plate are convenient to replace.
