Description

Technical Field

[0001] The utility model relates to the technical field of brake calipers, in particular to a brake caliper spring piece and a brake caliper structure with the spring piece. Background Art

[0002] The caliper disc brake is a type of disc brake. Its rotating element is a metal disc that works on the end surface, called a brake disc. The fixed element is a brake pad composed of a friction block with a small working area and its metal backing plate. There are 2 to 4 brake pads in each brake. These brake pads and their actuators are installed in a clamp-shaped bracket across the two sides of the brake disc, collectively called a brake caliper.

[0003] At present, the braking process is usually performed by the piston driving the friction block to move on the caliper body to brake. However, the piston reacts slowly when driving the friction block to move, and there is a certain reaction time. This results in a slow rebound speed of the friction block when it rebounds after braking is completed, and it will produce friction with the brake disc for a period of time. Long-term use will wear the friction block and the brake disc, and reduce the life of the friction block and the brake disc. In order to reduce the contact time between the brake disc and the friction block, a spring sheet is usually arranged on the caliper body. The spring sheet contacts the friction block and causes the spring sheet to deform during braking. After braking, the spring sheet resets, thereby causing the friction block to quickly reset. However, when the friction block moves during the braking process, the spring sheet receives an extrusion force, which is also easy to cause the position of the spring sheet to move. After long-term use, the spring sheet fails and cannot drive the friction block to quickly reset. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The locking part comprises a limit plate 14, and the limit plate 14 is located between the first side plate 2 and the second side plate 3. The limit plate 14 is arranged opposite to the reset part. A second locking groove 15 is provided on the limit plate 14, and a second locking plate 16 is arranged in the second locking groove 15. One end of the second locking plate 16 is fixedly connected to the limit plate 14, and the second locking plate 16 is inclined to the outside of the sliding groove. The other end of the second locking plate 16 abuts against the caliper body. During the braking process of the friction block, the second locking plate 16 can be limited and locked to prevent the spring piece from moving. In the utility model, the brake caliper spring piece is fixedly arranged on the brake caliper body, the friction block is slidably arranged in the sliding groove of the spring piece, and one side of the friction block is in contact with the reset part. When the friction block brakes, the friction block slides in the sliding groove and squeezes the reset part to cause the reset part to deform. When the braking is completed, the braking force of the friction block disappears, the deformation of the reset part is restored, and at the same time, the friction block can be quickly driven to reset, so that the friction block and the brake disc are quickly separated, reducing the contact time. At the same time, the clamping part is clamped with the caliper body to fix the spring piece on the caliper body, and the locking part can lock and fix the spring piece and the caliper body. During the braking process, the friction block spring piece will not move relative to the caliper body, thereby making the connection between the spring piece and the caliper body more stable and firm, preventing insufficient braking.

[0032] Furthermore, a second locking groove 6 is provided on the baffle 5, and a second locking plate 7 is arranged in the second locking groove 6. The second locking plate 7 is inclined toward the inside of the clamping part, one end of the second locking plate 7 is fixedly connected to the baffle 5, and the other end is located between the baffle 5 and the first side plate 2. The first locking plate 7 is clamped on the caliper body so that the spring sheet is fixedly connected to the caliper body.

[0033] Furthermore, the clamping portion also includes a positioning plate 8 and a clamping plate 9, and the positioning plate 8 and the clamping plate 9 are both fixedly connected to the connecting plate 5, and the positioning plate 8 and the clamping plate 9 are relatively arranged, and the positioning plate 8 and the clamping plate 9 are both located between the first side plate 2 and the baffle 5, and the positioning plate 8 is a flat plate, and the clamping plate 9 is bent. In this embodiment, the pliers body is located between the positioning plate 8 and the clamping plate 9, so the positioning plate 8 and the clamping plate 9 clamp the pliers body, and the clamping plate 9 is bent and has a certain elasticity, so the pliers body can be clamped and fixed to prevent the spring sheet from falling off the pliers body.

[0034] Furthermore, the reset portion includes a rebound plate 10 and a support plate 11, one end of the rebound plate 10 is connected to the support plate 11, the rebound plate 10 and the support plate 11 are located between the first side plate 2 and the second side plate 3, the other end of the rebound plate 10 is also connected to the bottom plate 1, a stress hole 12 is provided on the rebound plate 10, which can reduce the stiffness of the rebound plate 10 and improve the elasticity of the rebound plate 10, the rebound plate 10 is bent, so the rebound plate 10 will deform after being subjected to a certain pressure, and when the external pressure disappears, the rebound plate 10 quickly rebounds and resets under the action of the rebound force, thereby driving the friction block to quickly reset.

[0035] Furthermore, an abutting plate 13 is provided at one end of the support plate 11 away from the rebound plate 10 , and the abutting plate 13 abuts against the friction block, and the abutting plate 13 can increase the contact area between the abutting plate 13 and the friction block.

[0036] Furthermore, a balance plate is fixedly connected to one end of the second side plate 3 away from the bottom plate 1. The balance plate is arranged parallel to the bottom plate 1 and abuts against the side wall of the caliper body, which can balance the force of the spring sheet during braking, thereby improving the stability of the spring sheet and avoiding failure of the spring sheet.

[0037] A brake caliper structure includes a caliper body 17, a hydraulic cylinder, a friction block 18 and a brake caliper spring piece, wherein the brake caliper spring piece is fixedly arranged on the caliper body 17, the friction block 18 is slidably arranged in a sliding groove, one side of the friction block 18 is in contact with an abutment plate 13, and the hydraulic cylinder is fixedly arranged on the caliper body 17 and is used to drive the friction block 18 to slide.

[0038] Furthermore, a mounting block is provided on the caliper body 17, the clamping portion is fixedly provided on the mounting block, a clamping platform is provided on the side wall of the mounting block, one end of the first locking plate 7 abuts against the step surface of the clamping platform to prevent the spring piece from falling off, and at the same time, the positioning plate 8 and the clamping plate 9 cooperate with each other to clamp and fix the mounting block, so that the spring piece will not shake and fall off during the braking process.

[0039] Furthermore, the hydraulic cylinder is fixedly arranged on the caliper body 17, and the piston rod on the hydraulic cylinder is fixedly connected to one side of the friction block 18, so that the hydraulic cylinder can drive the friction block 18 to slide, and the abutment plate 13 abuts against the other side of the friction block 18.

[0040] Furthermore, sliding blocks are arranged on both sides of the friction block 18, and the sliding blocks are slidably arranged in the sliding grooves, and the sliding blocks abut against the abutment plates 13; when the friction block moves to brake, the hydraulic cylinder pushes the friction block 18 to move, and the friction block 18 applies pressure to the rebound plate 10 to deform the rebound plate 10, and the friction block is easy to drive the entire spring sheet to move during the extrusion process, and the positioning plate 8 and the clamping plate 9 fix the spring sheet and the caliper body, but the clamping plate 9 is a curved structure, which is also easy to deform after being subjected to pressure, so that the spring sheets cannot be fixed, causing the spring sheets to change position. The first locking plate 16 is arranged opposite to the reset portion, so the first locking plate 16 is located on the side of the friction block 18 away from the abutting plate 13, and the first locking plate 16 is a straight plate, which is not easy to deform. When the hydraulic cylinder drives the friction block 18 to brake, the friction block 18 moves to one side of the brake disc. Since the first locking plate 16 is abutted against the caliper body 17, the friction block 18 can be prevented from driving the spring piece to move, so that the spring piece can remain stable during the braking process to avoid shaking.
