Description

Technical Field

[0001] The utility model relates to the technical field of motor vehicles, in particular to a motor vehicle caliper. Background Art

[0002] Car calipers, usually located inside the wheel hub, are the core actuators of the car's braking system. They act like a powerful pair of pliers, tightly clamping the brake disc and using friction to slow down or stop the vehicle.

[0003] For example, the brake caliper used in the braking system of a motor vehicle with the authorization announcement number "CN201866139U" has good adhesion through the sliding spiral pair of parts, and the coating has extremely high wear resistance, excellent temperature performance and corrosion resistance, and has the characteristics of higher reliability, good processability and good economy. However, the device is not convenient for replacing the friction plate during use. The device requires the caliper to be disassembled before the friction plate is replaced. After the vehicle has been used for a period of time, the caliper of the car needs to be replaced or the friction plate is replaced, which makes the device inconvenient to replace during use. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the device is inconvenient to replace and causes inconvenience in use, and to propose a motor vehicle caliper.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A motor vehicle caliper is designed, comprising a caliper body and a piston. The inner wall of the caliper body is slidably connected to the piston, one end of the piston is provided with a replacement structure, and the outer wall of the piston is provided with a threaded hole.

[0007] Preferably, the replacement structure includes a bolt and a base plate, one end of the base plate is fitted with one end of the piston, the lower end of the base plate is fixedly connected to a right-angle block, the right-angle block is slidably connected to the bolt through a through hole opened on the surface, one end of the bolt passes through the right-angle block, and the upper end of the bolt is connected to the piston thread.

[0008] Preferably, the base plate is plugged into a groove provided on the surface of the piston through a protruding portion at one end, and a plurality of friction plates are fixedly connected to one end of the base plate.

[0009] Preferably, the grooves provided on the surface of the piston are trapezoidal grooves, and there are two grooves provided on the surface of the piston.

[0010] The motor vehicle caliper proposed by the utility model has the following beneficial effects: by replacing the structure and the cooperation of the piston, when the brake disc is worn, the operator rotates the bolt, removes the bolt, pulls down the base plate and the friction plate, and extracts the base plate from the groove on the piston surface. After the operator replaces the new one, the operator can continue to use it by reinstalling it according to the above reverse operation. The friction plate can be replaced, making the device more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Refer to the attached Figure 1-6: In this embodiment, a motor vehicle caliper includes a caliper body 1 and a piston 3. The inner wall of the caliper body 1 is slidably connected to the piston 3. This connection relationship has been disclosed in the prior art. The brake pump body transports the brake oil so that the brake oil can push the piston 3 to move, so that the piston 3 can drive the friction plate 4 to press against the surface of the brake disc through the bottom plate 203 to achieve the purpose of deceleration. A replacement structure 2 is provided at one end of the piston 3. A threaded hole is opened on the outer wall of the piston 3. The replacement structure 2 includes a bolt 202 and a bottom plate 203. The bottom plate One end of 203 fits with one end of the piston 3, and the lower end of the base plate 203 is fixedly connected to a right-angle block 201. The right-angle block 201 is slidably connected to the bolt 202 through a through hole opened on the surface. One end of the bolt 202 passes through the right-angle block 201, and the upper end of the bolt 202 is threadedly connected to the piston 3. The base plate 203 is plugged into the groove opened on the surface of the piston 3 through the protruding part at one end. One end of the base plate 203 is fixedly connected to a plurality of friction plates 4. The groove opened on the surface of the piston 3 is a trapezoidal groove, and there are two grooves on the surface of the piston 3.

[0020] Working principle:

[0021] When using calipers on motor vehicles:

[0022] The operator processes the caliper body 1 and installs it on the brake disc (this operation is existing technology and will not be described in detail here). When braking is required, the brake pump body is started to transport the brake oil, so that the brake oil can push the piston 3 to move, so that the piston 3 can drive the friction plate 4 through the bottom plate 203 to press against the surface of the brake disc to achieve the purpose of deceleration.

[0023] Replacement process:

[0024] When the brake disc is worn, the operator turns the bolt 202, removes the bolt 202, pulls down the base plate 203 and the friction plate 4, and extracts the base plate 203 from the groove on the surface of the piston 3. After the operator replaces the new one, it can be installed here according to the above reverse operation and can continue to be used. When replacing, there is no need to disassemble the caliper body 1.

[0025] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
