Wherein, both the brake pads are connected on the clamp body bracket in a sliding way. Therefore, when the brake is used, under the action of air pressure or hydraulic pressure, the piston of the piston cylinder drives one brake pad to press the brake disc, when the brake pad collides with the brake disc to generate enough pressure, the floating clamp slides towards the direction opposite to the movement of the piston, so that the other brake pad is driven to be close to the brake disc, and the two brake pads clamp the brake disc oppositely to brake. Since the brake caliper needs one brake pad to collide with the brake disc before the other brake pad starts to approach the brake disc, the brake system has a long brake period, thereby affecting the braking performance of the brake caliper.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Referring to fig. 1 and 2, there is shown a conventional floating caliper 2 disc brake caliper, the floating caliper 2 disc brake caliper including a caliper body bracket 1 for supporting, a floating caliper 2 slidably coupled on the caliper body bracket 1, a piston cylinder mounted on the floating caliper 2, and a first brake pad 4 and a second brake pad 5 for clamping a brake disc 6. The first brake block 4 and the second brake block 5 are both connected to the caliper body bracket 1 in a sliding mode, and the second brake block 5 is located at the front end of a piston 3 of a piston cylinder. The caliper body holder 1 is further provided with a guide pin 7, the floating caliper 2 is axially movable along the guide pin 7, and the movement locus of the first brake pad 4, the second brake pad 5, and the piston 3 is parallel to the movement locus of the floating caliper 2. Therefore, when the floating caliper 2 brakes through a disc brake caliper, the piston 3 is stressed to move rightwards and pushes against the second brake pad 5, and then the second brake pad 5 is driven to press the brake disc 6.
Specifically, referring to fig. 1, fig. 1 is a schematic structural view of the second brake pad 5 just colliding with the brake disc 6, and it can be seen that the distance between the first brake pad 4 and the brake disc 6 is not changed when the piston 3 moves to the state shown in fig. 1. Referring to fig. 2, fig. 2 is a schematic structural view illustrating that both the first brake pad 4 and the second brake pad 5 collide with the brake disc 6 for braking. Specifically, based on the state shown in fig. 1, the piston 32 is driven by force, increasing the interference force against the brake disk 6, thereby generating a reaction force, so that the floating caliper 2 slides on the guide pin 7 in the direction opposite to the movement of the piston 3. Thus, the first brake pad 4 is driven to press against the brake disc 6 after colliding against the second brake pad 5 until a clamping force is generated against the brake disc 6 simultaneously with the second brake pad 5, by which the braking is performed.
Therefore, when the floating caliper 2 is used for disc brake caliper braking, the first brake pad 4 and the second brake pad 5 lengthen the braking period, which affects the braking performance of the brake system.
Referring to fig. 3-7, the embodiment of the invention provides a return lever type brake caliper, which comprises a caliper body support 1, a floating caliper 2 connected to the caliper body support 1 in a sliding manner, and a piston cylinder fixed on the floating caliper 2, wherein an accommodating groove 8 is formed in the floating caliper 2 or the piston cylinder.
The brake caliper further comprises a support arm 11 and a lever assembly located in the accommodating groove 8, the lever assembly comprises a first deformation mechanism 9 and a second deformation mechanism 10, the first deformation mechanism 9 and the second deformation mechanism 10 are respectively connected to the support arm 11 in a rotating mode, the first deformation mechanism 9 abuts against the piston 3 of the piston cylinder, and the second deformation mechanism 10 abuts against the groove wall of the accommodating groove 8; and the number of the first and second electrodes,
when the piston 3 moves, the first deformation mechanism 9 and the second deformation mechanism 10 are driven to rotate around the support arm 11, so that the floating clamp 2 and the piston 3 move in the horizontal direction in an opposite or opposite direction.
In an embodiment of the present invention, referring to fig. 3, the brake caliper includes a caliper body bracket 1, a floating caliper 2, a piston cylinder, a first brake pad 4, and a second brake pad 5. The caliper body bracket 1 plays a role in supporting and fixing, and the floating caliper 2, the first brake pad 4 and the second brake pad 5 are arranged on the caliper body bracket 1. The brake caliper can be fixed by connecting the caliper body bracket 1 to the knuckle 15. The floating caliper 2 is connected to the caliper body support 1 in a sliding mode through a guide shaft, the piston cylinder is fixed to the floating caliper 2, and the first brake disc 4 and the second brake disc 5 are used for clamping the brake disc 6. The first brake block 4 and the second brake block 5 are both connected to the caliper body bracket 1 in a sliding mode, and the second brake block 5 is located at the front end of a piston 3 of a piston cylinder. The floating caliper 2 axially moves along the guide shaft, and the movement locus of the first brake disc 4, the second brake disc 5, and the piston 3 is parallel to the movement locus of the floating caliper 2.
In addition, the brake caliper includes a support arm 11 and a lever assembly. The arm 11 is used to connect the lever assembly and provide a fulcrum for the lever assembly. The lever assembly is used for conducting a driving force to the floating clamp 2 under the condition that the piston 3 moves according to the lever principle. So that the floating caliper 2 can move horizontally away from the piston 3 without the second brake pad 5 interfering with the brake disc 6. In one example, the accommodating groove 8 for accommodating the lever assembly may be formed in the floating caliper 2 or the piston cylinder, specifically, the lever assembly may include a first deformation mechanism 9 and a second deformation mechanism 10, the first deformation mechanism 9 and the second deformation mechanism 10 are respectively rotatably connected to the support arm 11, wherein the first deformation mechanism 9 is penetrated by the piston cylinder and is abutted against the piston 3, and the second deformation mechanism 10 is abutted against the groove wall of the accommodating groove 8.
Referring to fig. 4, a structural diagram of the brake caliper during braking is shown, specifically, during braking, the piston 3 pushes the second brake pad 5 to horizontally approach the first brake pad 4, a driving force is generated between the first deformation mechanism 9 and the piston 3, the end of the first deformation mechanism 9 is driven to synchronously displace with the piston 3, and the end of the second deformation mechanism 10 is caused to displace in the opposite direction through the support arm 11. Under the condition that the second brake pad 5 is not collided with the brake disc 6, the first brake pad 4 is driven to be close to the brake disc 6, and the first brake pad 4 and the second brake pad 5 move oppositely to realize the rapid clamping of the brake disc 6. The time difference of the two brake pads contacting the brake disc 6 is reduced, and the braking efficiency of the brake caliper is improved. Meanwhile, the abrasion degree of the single-side brake block is reduced.
Referring to fig. 5, a structural diagram of the brake caliper when the brake is released is shown, specifically, when the piston 3 starts to retract after the brake is released, the end of the first deformation mechanism 9 is displaced synchronously with the piston 3, and the end of the second deformation mechanism 10 is displaced in the opposite direction through the support arm 11, so that the floating caliper 2 drives the first brake pad 4 away from the brake disc 6. Therefore, when the piston 3 begins to retract, the first brake pad 4 and the second brake pad 5 synchronously move back to back, and the brake disc 6 is quickly loosened, so that brake dragging of the brake caliper is reduced, and the product performance of the brake caliper is improved.
Referring to fig. 6 and 7, in an alternative embodiment of the invention, the lever assembly further includes a rotating flange 12, the rotating flange 12 is press-fitted on the arm 11 through a pin, and the first deforming mechanism 9 and the second deforming mechanism 10 are respectively fixed on the rotating flange 12.
In the embodiment of the present invention, the lever assembly further includes a rotating flange 12, specifically, an inner ring of the rotating flange 12 may be press-fitted on the support arm 11 through a pin, and the first deforming mechanism 9 and the second deforming mechanism 10 are respectively fixed on an outer ring of the rotating flange 12.
Referring to fig. 6, in an alternative embodiment of the invention, the first deformation mechanism 9 includes a connecting rod 901, a slider 902, a steel ball 903 embedded in the slider 902, and a spring 904 connected to the steel ball 903.

In the embodiment of the invention, because the distance between the support arm 11 and the piston 3 is not changed, the first deformation mechanism 9 needs to self-adapt to the distance between the support arm 11 and the piston 3 through self deformation in the rotation process so as to ensure that the first deformation mechanism and the piston 3 are always in an interference state. Illustratively, the first deforming mechanism 9 may include a link 901, a slider 902, a steel ball 903 embedded in the slider 902, and a spring 904 connected to the steel ball 903. One end of the connecting rod 901 can be fixed on the outer ring of the rotary flange 12, and the other end of the connecting rod 901 penetrates the inside of the sliding block 902 and is connected with the steel ball 903. Since the steel ball 903 presses the spring 904 against the end surface of the slider 902 close to the piston 3, the spring 904 is always kept in a compressed state when the spring 904 is kept in the compressed state and the first deforming mechanism 9 is rotated, so that the slider 902 can keep abutting against the piston 3.
In an alternative embodiment of the invention, the second deformation mechanism 10 and the first deformation mechanism 9 are identical in structure.
The link 901 of the first deforming mechanism 9 and the link 901 of the second deforming mechanism 10 are arranged in line.

Also, the link 901 of the first deformation mechanism 9 and the link 901 of the second deformation mechanism 10 may be provided in line. Specifically, the structural identity means that the second deformation mechanism 10 also includes the link 901, the slider 902, the steel ball 903 embedded in the slider 902, and the spring 904 connected to the steel ball 903 in the first deformation mechanism 9. However, in the two deformation mechanisms, the size of each element may be different, for example, the length of the link 901 of the first deformation mechanism 9 and the length of the link of the second deformation mechanism 10 may be different, and those skilled in the art can select the length according to actual situations, which is not limited herein.
Referring to fig. 6, in an alternative embodiment of the present invention, guide rails 13 are respectively disposed on the groove walls of the piston 3 and the accommodating groove 8, and the guide rails 13 are movably connected to the sliding block 902.

Referring to fig. 6, in an alternative embodiment of the invention, a protrusion 14 for abutting against the sliding block 902 is provided at both ends of the guide rail 13 to allow the lever assembly to rotate around the arm 11.
In the embodiment of the present invention, the two ends of the guide rail 13 are provided with the protrusions 14 for abutting against the slider 902, and when the slider 902 abuts against the protrusions 14, the protrusions 14 can prevent the slider 902 from continuously sliding, so as to limit the slider 902. The lever assembly is thus driven in a rotational movement about the arm 11 under the movement of the piston 3.
In an optional embodiment of the invention, the groove walls of the piston 3 and the accommodating groove 8 are respectively provided with a limiting groove, and the guide rail 13 is positioned in the limiting groove; wherein the content of the first and second substances,
