[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] See also Figures 1 to 4 As shown;

[0039] A caliper friction plate return structure of this embodiment is assembled and fixed on a caliper body 10 of a vehicle, and the structure includes:

[0040] Cross spring 20; and

[0041] A pin shaft 30 connected to both ends of the cross spring 20, and the cross spring 20 is connected to the caliper body 10 through the pin shaft 30;

[0042] The pin shaft 30 is configured as a shoulder structure that is thin in the middle and thick at both ends, and the cross spring 20 is connected to the middle portion of the pin shaft 30 .

[0043] Specifically, the present embodiment discloses a caliper friction plate return structure, which includes a cross spring 20 and two pins 30. The cross spring 20 of the present embodiment is assembled and fixed to the caliper body 10 by the two pins 30, and the pins 30 of the present embodiment are a shoulder structure that is thin in the middle and thick at both ends, which can limit the tangential movement of the cross spring 20.

[0044] Preferably, this embodiment further defines the structure of the pin 30, specifically: the pin 30 includes:

[0045] The intermediate rod 31 and the end rods 32 formed at both ends of the intermediate rod 31 ; the diameter of the intermediate rod 31 is smaller than the diameter of the end rod 32 .

[0046] Preferably, the cross spring 20 of this embodiment includes a wedge-shaped spring leaf 1; and a wave spring leaf 2 connected to the wedge-shaped spring leaf 1;

[0047] The wedge-shaped spring piece 1 and the wave-shaped spring piece 2 are arranged in a cross shape, the center positions of the two overlap and are connected by a rivet 3;

[0048] Both ends of the wave spring 2 are formed as pin mounting portions connected to the pin 30 .

[0049] The wedge-shaped spring 1 of this embodiment has a wedge-shaped spring middle portion 101 and wedge-shaped portions 102 formed at both ends of the wedge-shaped spring middle portion 101 ; the length of the wedge-shaped spring middle portion 101 is greater than the width of the wave spring 2 .

[0050] Preferably, the position where the wave spring 2 of this embodiment cooperates with the middle portion 101 of the wedge-shaped spring is a plane, and both ends of the wave spring 2 are wave structures 201 with multiple bending parts.

[0051] The pin shaft mounting portion of this embodiment includes a mounting portion 202 of an arc-shaped structure and a limiting portion 203 formed on the mounting portion 202 ; the space between the mounting portion 202 and the limiting portion 203 is a penetration space 204 for the pin shaft 30 .

[0052] This embodiment further defines the composition of the cross spring 20, which includes a wedge-shaped spring leaf 1 and a wave spring leaf 2 distributed in a cross shape; the wedge-shaped spring leaf 1 and the wave spring leaf 2 of this embodiment need to be pressed during assembly to provide initial pressure to the cross spring 20. When the friction plate is not subjected to force, the back plate of the friction plate is clamped in the middle position of the wedge-shaped spring leaf 1 under the action of the initial pressure, thereby playing the role of fixing the friction plate. When the friction plate is subjected to tangential movement by the piston pressure, the wedge-shaped spring leaf 1 is elastically deformed by force. The greater the displacement of the friction force, the greater the deformation of the wedge-shaped spring leaf 1, and the greater the elastic force provided. Therefore, when the piston force disappears, the friction plate can be quickly pressed back to the initial position, making the return more stable and efficient. The design of the wave spring leaf 2 improves the strength of the cross spring 20, can store greater elastic force, and effectively extends the service life of the return structure.

[0053] In the above technical solution, the utility model provides a caliper friction plate return structure, which has the following beneficial effects:

[0054] The return structure of the utility model is connected to the caliper body 10 through the cross spring 20 and the pin shaft 30 of the shoulder structure, which can optimize the smoothness of the return of the friction plate, reduce the drag torque, and improve the overall performance of the braking system.

[0055] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
