Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, and in particular to a floating caliper for motorcycles. Background Technology

[0002] Currently, most motorcycle braking systems use floating calipers. When a floating caliper is in operation, the piston pushes the inner friction pad to the right, while simultaneously moving the caliper body and the outer friction pad to the left, thus clamping the brake disc. When the braking system is disengaged, the return ring moves the piston back to its original position, and the inner and outer friction pads disengage from the brake disc. At this point, due to factors such as vehicle resonance, contact stress will be generated at the contact point between the outer friction pad and the caliper body, which will affect the performance of the caliper in the later stages of its lifespan.

[0026] refer to Figure 1-6 As shown, one embodiment of this utility model is as follows:

[0027] A floating caliper for motorcycles includes a caliper body 1, a piston chamber 2 inside the caliper body 1, a brake piston 3 inside the piston chamber 2, an inner friction plate 4 at the end of the brake piston 3, a fixing groove 5 on the caliper body 1 relative to the inner friction plate 4, an outer friction plate fixing plate 6 on the fixing groove 5, and the outer friction plate fixing plate 6 including a first platform portion 61, a V-shaped connecting portion 62 and a second platform portion 63 arranged sequentially from the inside to the outside, the first platform portion 61 being located above the second platform portion 63, and the first platform portion 61 being connected to the outer friction plate 8 by fixing bolts 7.

[0028] Specifically, the clamp body 1 is provided with a sliding sleeve 9, the sliding sleeve 9 is connected to a sliding shaft 10, the sliding shaft 10 is connected to a fixed bracket 11, and the fixed bracket 11 is provided with a fixing hole 12.

[0029] The piston chamber 2 is provided with a mounting groove, and the mounting groove is provided with a return ring 13 adapted to the brake piston 3.

[0030] The clamp body 1 is installed in conjunction with the fixed bracket 11 via the sliding sleeve 9 and the sliding shaft 10, so that the clamp body can move axially relative to the mounting bracket.

[0031] During braking, the brake fluid pushes the brake piston 3 to the right from the rear of the piston chamber 2, which in turn pushes the inner friction pad to the right. At the same time, it drives the caliper 1 and the outer friction pad 8 to the left, thereby clamping the brake disc 14 and achieving smooth braking of the motorcycle. In the braking state, the return ring undergoes elastic deformation. After the brake is released, the return ring returns to its initial deformation, which drives the brake piston to return to its original position. The inner and outer friction pads disengage from the brake disc 14, and the brake is released.

[0032] like Figure 5 As shown in Figure 6, the outer friction plate fixing plate includes a first platform portion 61, a V-shaped connecting portion 62, and a second platform portion 63 arranged sequentially from the inside out. The first platform portion 61 has a first threaded hole 611 at its center, adapted to accommodate the fixing bolt. To accommodate the clamp structure and facilitate installation, the outer friction plate fixing plate is circular in shape, with a horizontal cross-section at its upper part. The outer second platform portion 63 is connected and fixed to the fixing groove, specifically by threaded connection or welding. In this embodiment, welding is used to ensure connection strength.

[0033] The outer friction plate fixing plate is integrally formed and connects the first platform and the second platform through the V-shaped connecting part 62, so that the first platform is located above the second platform. After assembly, as shown... Figure 2As shown, the first platform 61 is closer to the inner friction plate 4 than the second platform 62. Connecting the outer friction plate 8 to the first platform 61 with fixing bolts 9 can effectively eliminate contact stress, ensuring that it cannot move under any operating conditions of the vehicle, thus ensuring the performance of the caliper in the later stages of its life cycle.

[0034] During installation, in order to improve assembly efficiency and accuracy, this embodiment provides a positioning block 64 at the lower end of the second platform part 63, and a positioning groove 51 adapted to the positioning block is provided at the lower end of the fixing groove 5.

[0035] In this embodiment, the outer friction plate 8 includes a steel back plate 81, the front side of which is provided with a friction substrate plate 82, and the back side of which is provided with a second screw hole 811 adapted to the fixing bolt 7.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
