Description

Technical Field

[0001] The utility model relates to a disc brake, in particular to a disc brake with a friction plate that is easy to disassemble. Background Art

[0002] Disc brakes are brakes used on automobiles. Their main working principle lies in the hydraulic control system. They are composed of brake discs, brake calipers, friction pads, oil pipes, etc. Pressure is applied to the brake caliper, causing the brake caliper friction pads to rub against the wheel brake disc to achieve the purpose of braking.

[0003] The friction pads in disc brakes will continue to wear during use. When worn to a certain extent, the braking effect will be weakened, thus affecting the safety of vehicle driving. Therefore, the friction pads need to be replaced regularly. At present, when the friction pads in disc brakes are disassembled and replaced, they need to be disassembled and replaced together with the fixing accessories. In addition, since the fixing accessories are located inside the brake caliper, the operating space is limited and the matching relationship is complex, which makes the removal and installation of the friction pads difficult, time-consuming and labor-intensive, and brings inconvenience to the replacement of the friction pads.

[0004] Therefore, it is urgent to provide a disc brake that is easy to disassemble the friction plate. Utility Model Content

[0005] In order to overcome the disadvantages that when the friction plate in the existing disc brake is disassembled and replaced, it is necessary to disassemble and replace it together with the fixing accessories, and because the fixing accessories are located inside the brake caliper, the operation space is limited and the matching relationship is complicated, which makes disassembly and installation difficult, time-consuming and labor-intensive, and brings inconvenience to the replacement of the friction plate, the utility model provides a disc brake with easy disassembly of the friction plate.

[0006] To solve the above problem, the utility model adopts the following technical scheme: a disc brake with easy-to-remove friction plates, comprising a brake disc, a brake caliper mounted on the brake disc, symmetrically distributed friction plates arranged in the brake caliper, the friction plates being radially movable, a piston being slidably mounted on the inner side wall of the brake caliper, the piston being able to telescope and control the movement of the friction plates on one side, a pressure plate being arranged on the friction plate, a clamping plate being rotatably arranged on the brake caliper, the clamping plate cooperating with the pressure plate to press the friction plate, and a screw button for fixing the clamping plate being threadedly arranged on the brake caliper.

[0007] Optionally, a No. 1 rack is provided on both sides of the friction plate, and a plurality of No. 2 racks are slidably provided on the brake caliper, and a gear is provided between the adjacent No. 1 racks and the No. 2 racks, and the gear is meshed with the No. 1 rack and the No. 2 rack.

[0008] Optionally, a heat conducting plate is provided on the brake caliper, and a temperature detector is provided on the heat conducting plate via a mounting frame.

[0009] Optionally, two limit blocks located on both sides of the clamping plate are fixedly connected to the brake caliper, and a stop rod is slidably provided on the two limit blocks.

[0010] Optionally, a protective pad is provided on the side of the piston that contacts the friction plate.

[0011] Optionally, ventilation holes for ventilation and heat dissipation are provided on the surface of the brake disc.

[0012] Compared with the prior art, the utility model has the following technical effects: 1. The friction plate is fixed by pressing the pressure plate with a clamping plate, and the clamping plate is arranged outside the brake caliper for easy operation. The clamping plate is rotatable and can be rotated to loosen the friction plate without removal, which facilitates the disassembly and installation of the friction plate.

[0013] 2. Through the cooperation of rack No. 2, gear and rack No. 1, when the clamping plate releases the friction plate, the friction plate can be moved out of the brake caliper, which is convenient and quick to remove.

[0014] 3. Through the setting of the heat conduction plate and the temperature detector, the brake disc temperature can be monitored in real time when the brake disc is in operation, and warnings and reminders can be given when the brake disc temperature exceeds the normal range.
