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 block composed of a friction block with a small working area and its metal backing plate. There are 2 to 4 brake blocks in each brake. These brake blocks and their actuators are installed in a clamp-shaped bracket spanning both sides of the brake disc, collectively called a brake caliper. The brake disc and the brake caliper together constitute a caliper disc brake.

[0003] During the braking process, the hydraulic cylinder installed on the caliper body drives the friction block to slide to one side of the brake disc, so that the friction block and the brake disc rub against each other to brake the vehicle. After the braking is completed, the hydraulic cylinder quickly resets, but the friction block and the brake disc are not separated yet. The two are in contact. The friction block will slowly separate from the brake disc during the vehicle's driving, which will cause a certain amount of resistance to the vehicle. At the same time, the friction generated by the contact between the two will also produce a certain amount of shadow, affecting the driver's driving experience. Utility Model Content

[0029] like Figures 1 to 3As shown, a brake caliper spring piece includes a sliding portion, a clamping portion and a reset portion, the sliding portion is fixedly arranged on the caliper body, the sliding portion includes a bottom plate 4, a first side plate 5 and a second side plate 6, the first side plate 5 and the second side plate 6 are respectively fixedly connected to the two ends of the bottom plate 4, the first side plate 5 and the second side plate 6 are relatively arranged, the bottom plate 4, the first side plate 5 and the second side plate 6 are surrounded to form a sliding groove, the friction block is slidably arranged in the sliding groove, the clamping portion is fixedly connected to the sliding portion, the clamping portion is used to be fixedly connected to the caliper body, the reset portion includes a rebound plate 1, a first connecting plate 2 and an abutting plate 3, the rebound plate 1 is fixedly connected to the bottom plate 4, the first connecting plate 2 is fixedly connected to the rebound plate 1, the abutting plate 3 is fixedly connected to the first connecting plate 2, the rebound plate 1 and the abutting plate 3 They are respectively located at both ends of the first connecting plate 2, and the rebound plate 1, the first connecting plate 2 and the abutment plate 3 are all located between the first side plate 5 and the second side plate 6. In the utility model, the spring sheet is fixedly connected to the caliper body by a clamping portion, and the friction block is slidably arranged in the sliding groove, and the side of the friction block facing the brake disc abuts against the abutment plate 3. During the braking process of the vehicle, the friction block moves toward one side of the brake disc, so that the friction block and the brake disc are in contact and friction, and the friction block will drive the abutment plate 3 to move during the movement, thereby causing the rebound plate 1 to deform. After the braking is completed, the pressure applied to the friction block disappears, and the rebound plate 1 can rebound quickly, thereby driving the abutment plate 3 to reset, and the abutment plate 3 is in contact with the friction block, so it can drive the friction block to reset quickly, thereby reducing the contact time between the friction block and the brake disc.

[0030] Furthermore, the rebound plate 1 is bent and protrudes to the side away from the sliding groove, so that the rebound plate 1 can be deformed after being subjected to a force, and can also rebound and reset quickly when the force disappears; a stress hole 7 is opened on the rebound plate 1, which can reduce the stress generated by the rebound plate 1 during the deformation process, avoid damage to the rebound plate 1, and increase the service life.

[0031] Furthermore, the rebound plate 1 includes a first elastic plate and a second elastic plate, one end of the first elastic plate is fixedly connected to the bottom plate 4, and the other end is fixedly connected to the second elastic plate, the connection between the first elastic plate and the second elastic plate is smoothly transitioned, and the end of the second elastic plate away from the first elastic plate is fixedly connected to the first connecting plate 2, and the first elastic plate and the second elastic plate are both bent and protrude to the outside of the spring sheet. Since the first elastic plate and the second elastic plate are provided and both are bent, the rebound plate 1 has greater elasticity. Driven by the first elastic plate and the second elastic plate, the abutment plate 3 can drive the friction block to quickly reset, thereby accelerating the response speed.

[0032] Furthermore, the clamping portion includes a second connecting plate 8 and a clamping plate 9, the second connecting plate 8 is fixedly connected to one end of the first side plate 5 away from the bottom plate 4, the second connecting plate 8 is arranged parallel to the bottom plate 4, the clamping plate 9 is fixedly connected to one end of the second connecting plate 8 away from the first side plate 5, the clamping plate 9 is arranged opposite to the first side plate 5, and the clamping plate 9 is inclined to one side of the first side plate 5, so that the first side plate 5 and the clamping plate 9 cooperate with each other to clamp the pliers body so that the spring sheet is fixedly connected to the pliers body.

[0033] Furthermore, a locking groove 10 is provided on the clamping plate 9, and a locking plate 11 is arranged in the locking groove 10. The locking plate 11 is inclined toward one side of the first side plate 5. One end of the locking plate 11 fixedly connected to the clamping plate 9 is a fixed end, and the other end is a movable end. The movable end is located between the clamping plate 9 and the first side plate 5. The locking plate 11 can clamp the spring sheet on the pliers body to prevent the spring sheet from falling off.

[0034] Furthermore, a bending plate is provided at one end of the clamping plate 9 away from the first side plate 5, and the bending plate is inclined toward the side away from the first side plate 5. When removing the spring piece from the pliers body, it is only necessary to move the bending plate outward to separate the locking plate and the pliers body from each other, so that the spring piece can be removed from the pliers body.

[0035] Furthermore, the clamping portion also includes a fixing plate 12 and a limiting plate 13, and the fixing plate 12 and the limiting plate 13 are both fixedly connected to the second connecting plate 8, and the fixing plate 12 and the limiting plate 13 are relatively arranged, the fixing plate 12 is a straight plate, and the limiting plate 13 is a curved arrangement, and the limiting plate 13 is bent toward one side of the fixing plate 12, and the fixing plate 12 and the limiting plate 13 are both located between the first side plate 5 and the clamping plate 9, and the caliper body is located between the fixing plate 12 and the limiting plate 13, and the fixing plate 12 abuts against the side wall of the caliper body. Since the limiting plate 13 is a curved structure, it has a certain elasticity and can clamp the caliper body to prevent the spring sheet from moving on the caliper body during braking.

[0036] Furthermore, one end of the second side plate 6 away from the bottom plate 4 is fixedly connected to a support plate, the brake plate is arranged parallel to the bottom plate 4, and the support plate abuts against the side wall of the caliper body, so that the forces on both sides of the spring sheet can be balanced during braking, avoiding failure of the spring sheet due to uneven force after long-term use.

[0038] Furthermore, a mounting block is provided on the caliper body 14, and a clamping platform is provided on the side wall of the mounting block.
