Description

Technical Field

[0001] The present invention relates to the technical field of vehicle braking systems, and in particular to a floating caliper brake. Background Art

[0002] In a floating caliper brake system for automobiles, the brake pad is clamped and installed by a layer of U-shaped springs mounted on a bracket. The U-shaped springs are fixed in grooves in the bracket, and the brake pads are elastically clamped in the U-shaped springs. They can reciprocate relative to the U-shaped springs, allowing them to contact the brake disc under the clamping force of the caliper to brake. This clamping arrangement protects the bracket by applying the force of the brake pad through the springs during braking and prevents the pads from loosening and causing clattering noises during driving. However, the elastic clamping action of the U-shaped springs hinders the movement of the brake pads. After contact with the brake disc, the brake pads cannot fully disengage, resulting in drag. This increases vehicle energy consumption, increases wear on the brake disc and pads, and shortens their lifespan. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a floating caliper brake that can save energy, reduce the wear and loss of brake pads and brake discs, extend the service life, realize automatic compensation of wear, has a simple and compact structure, is easy to manufacture, and has low cost.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A floating caliper brake comprises a bracket and a brake pad, wherein the brake pad is mounted on the bracket in a manner capable of reciprocating linear motion via two connecting pieces located at both ends of the brake pad, the connecting piece comprising an outer connecting portion and an inner connecting portion, the outer connecting portion being mounted on the bracket, the inner connecting portion being provided with a mounting groove for elastically clamping the brake pad and allowing reciprocating linear motion of the brake pad, the inner connecting portion being connected to the outer connecting portion via an elastic connecting portion and capable of reciprocating linear motion relative to the outer connecting portion, the force required for elastic deformation of the elastic connecting portion being less than the static friction between the brake pad and the inner connecting portion.

[0006] As a further improvement of the above technical solution:

[0007] One direction of the reciprocating linear motion of the inner connecting part relative to the outer connecting part is a braking direction, and the inner connecting part or the elastic connecting part has a limiting part for limiting the movement stroke of the inner connecting part when the inner connecting part moves in the braking direction relative to the outer connecting part.

[0008] The connecting piece is an integral piece formed by bending a plate.

[0009] The plate includes a first part, a second part and a middle part, the first part and the second part are respectively connected to the two sides of the middle part, the first part is bent to form a U-shaped structure as the outer connection part, the second part is bent to form a U-shaped structure as the inner connection part, and the middle part is bent to form an elastic connection part of the U-shaped structure. The elastic connection part enables the inner connection part to be located in the groove formed by the outer connection part, and the inner connection part can reciprocate linearly in the groove relative to the outer connection part.

[0010] The elastic connecting portion includes a bottom edge, a first side edge and a second side edge. The first side edge and the second side edge are respectively connected to the two sides of the bottom edge to form a U-shaped groove. The first side edge is connected to the external connecting portion, and the second side edge is connected to the internal connecting portion and serves as the limiting portion.

[0011] The bottom edge is in an arc shape that is concave toward the outside of the U-shaped groove, so that the bottom width of the U-shaped groove is greater than the width of the open end.

[0012] The elastic connecting portion is located outside the groove formed by the external connecting portion.

[0013] The bracket is provided with a positioning groove, and the external connecting part is installed in the positioning groove.

[0014] The inner connecting portion includes a bottom plate portion and two side plate portions, the two side plate portions are respectively connected to both sides of the bottom plate portion to form the installation groove, and at least one side plate portion is bent at one end away from the bottom plate portion to form an elastic positioning portion protruding into the inside of the installation groove.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] In the floating caliper brake of the present invention, the inner connecting portion is connected to the outer connecting portion via an elastic connecting portion, enabling reciprocating linear motion relative to the outer connecting portion. The force required for elastic deformation of the elastic connecting portion is less than the static friction between the brake pad and the inner connecting portion. When the actuator drives the brake pad to brake, the brake pad first drives the inner connecting portion relative to the outer connecting portion, forcing the elastic connecting portion to deform. When the elastic connecting portion is not deformed enough to move the brake pad to the braking position (a position in contact with the brake disc), the brake pad can further move relative to the inner connecting portion to the braking position. After braking, the elastic recovery effect of the elastic connecting portion forces the inner connecting portion, carrying the brake pad, to return to the braking position in the opposite direction. Compared to conventional solutions, the brake pad is completely disengaged from the brake disc during return after braking, avoiding drag resistance, saving energy, reducing wear and tear on the brake pad and disc, and extending its service life. Furthermore, after the brake pad has experienced a certain amount of wear, the brake pad can still move relative to the inner connecting portion during braking, thereby automatically compensating for wear and ensuring effective braking. The floating caliper brake also has the advantages of simple and compact structure, easy manufacture and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4As shown, the floating caliper brake of this embodiment includes a bracket 1 and a brake pad 2. The brake pad 2 is mounted on the bracket 1 in a manner that allows reciprocating linear motion via two connecting members 3 located at both ends of the brake pad 2. The connecting member 3 includes an outer connecting portion 31 and an inner connecting portion 32. The outer connecting portion 31 is mounted on the bracket 1. The inner connecting portion 32 is provided with a mounting groove 33 for elastically clamping the brake pad 2 and allowing reciprocating linear motion of the brake pad 2. The inner connecting portion 32 is connected to the outer connecting portion 31 via an elastic connecting portion 34 and can reciprocate linear motion relative to the outer connecting portion 31. The force required for elastic deformation of the elastic connecting portion 34 is less than the static friction between the brake pad 2 and the inner connecting portion 32. The cam 32 is then released to allow the brake disc 2 to move in a direction opposite to the inner connection 32. The cam 32 is then released to allow the brake disc 2 to move in a direction opposite to the inner connection 32. The cam 32 is then released to allow the brake disc 2 to move in a direction opposite to the inner connection 32. Furthermore, after the brake pad 2 has worn to a certain extent, the brake pad 2 can still move relative to the inner connecting portion 32 during braking, thereby automatically compensating for the wear and ensuring the braking effect. The floating caliper brake also has the advantages of being simple and compact in structure, easy to manufacture, and low in cost.

[0025] In this embodiment, one direction of reciprocating linear motion of the inner connecting portion 32 relative to the outer connecting portion 31 is the braking direction. The inner connecting portion 32 or the elastic connecting portion 34 includes a limiting portion that limits the travel of the inner connecting portion 32 when the inner connecting portion 32 moves in the braking direction relative to the outer connecting portion 31. By limiting the travel of the inner connecting portion 32 relative to the outer connecting portion 31 in the braking direction, the limiting portion ensures that the brake pad 2 can move stably relative to the inner connecting portion 32 after a certain amount of wear occurs, ensuring that the wear can be automatically compensated.

[0026] In this embodiment, the connecting member 3 is an integral member formed by bending a plate, and has a simple structure, low cost, and is easy to manufacture.

[0027] In this embodiment, the plate includes a first portion, a second portion, and a middle portion. The first portion and the second portion are respectively connected to either side of the middle portion. The first portion is bent to form a U-shaped structure as the outer connecting portion 31, the second portion is bent to form a U-shaped structure as the inner connecting portion 32, and the middle portion is bent to form an elastic connecting portion 34 of the U-shaped structure. The elastic connecting portion 34 positions the inner connecting portion 32 in the groove formed by the outer connecting portion 31, and the inner connecting portion 32 can reciprocate linearly relative to the outer connecting portion 31 in the groove. Both the outer connecting portion 31 and the inner connecting portion 32 have a U-shaped structure, and the inner connecting portion 32 is positioned in the groove formed by the outer connecting portion 31. This results in a compact structure and high stability in the movement of the inner connecting portion 32.

[0028] In this embodiment, the elastic connection portion 34 includes a bottom edge 341, a first side edge 342, and a second side edge 343. The first side edge 342 and the second side edge 343 are respectively connected to the two sides of the bottom edge 341 to form a U-shaped groove 344. The first side edge 342 is connected to the outer connection portion 31, and the second side edge 343 is connected to the inner connection portion 32 and serves as a limiting portion. This structure of the elastic connection portion 34 has excellent elastic deformation performance, is simple in structure, low in cost, and easy to manufacture.

[0029] In this embodiment, the bottom edge 341 is in an arc shape that is concave toward the outside of the U-shaped groove 344 , so that the bottom width of the U-shaped groove 344 is greater than the width of the open end, which can further improve the elastic deformation performance of the elastic connection portion 34 .

[0030] In this embodiment, the elastic connection portion 34 is located outside the groove formed by the outer connection portion 31, so as not to interfere with the movement of the brake pad 2 or the action of the driver driving the brake pad 2.

[0031] In this embodiment, the bracket 1 is provided with a positioning groove 11, and the external connection part 31 is installed in the positioning groove 11, which can improve the installation stability of the connecting member 3 on the bracket 1 and has a compact structure.

[0032] In this embodiment, the inner connecting portion 32 comprises a bottom plate portion 321 and two side plates 322. The two side plates 322 are connected to either side of the bottom plate portion 321 to form a mounting groove 33. At least one end of the side plate 322, away from the bottom plate portion 321, is bent to form an elastic locating portion 323 that protrudes into the mounting groove 33. This elastic locating portion 323 effectively holds the brake pad 2 and ensures a suitable elastic clamping action, allowing the brake pad 2 to move relative to the inner connecting portion 32. This elastic locating portion 323 is simple and compact in structure, easy to manufacture, and low in cost.

[0033] The above is only a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiment. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of the present invention should also be considered as the scope of protection of the present invention.
