Description

Technical Field

[0001] The invention belongs to the field of mechanical technology, and in particular relates to a safe assembled brake caliper. Background Art

[0002] The brake caliper consists of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When braking, the high-pressure brake oil pushes the brake disc, thereby producing a braking effect. Disc brakes are sometimes also called disc brakes. They are divided into ordinary disc brakes and ventilated disc brakes. They are now widely used for front wheels. Some high-end cars are equipped with four-wheel disc brakes. Their advantages are sensitive action, good heat dissipation, no need to adjust the brake clearance, and easy maintenance.

[0003] In some existing brake calipers, the brake pads are installed inside. The brake pads are worn out by contact with the surface of the brake disc due to long-term braking use. Severely worn brake pads need to be removed and replaced to maintain the braking effect. To remove the brake pads, the entire brake caliper needs to be removed from the outside of the brake disc, which is inconvenient to operate.

[0004] In addition, most brake caliper piston return and clamping devices still use a single piston for braking, which has a poor force application effect. The piston needs to push the closer brake pad, and then the guide pin moves the housing to fit the other brake pad to the brake disc to generate braking force, which increases the braking time and reduces the braking performance. Summary of the invention

[0005] The purpose of the present invention is to provide a safe assembled brake caliper which is easy to disassemble and repair and has a good return effect in view of the above problems existing in the prior art.

DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present safety assembled brake caliper comprises a caliper as a whole 1, wherein the caliper as a whole 1 is composed of an upper caliper body 2 and a lower caliper body 3, a brake pad 6 is arranged on the caliper body, so that a braking space for the brake disc to brake is formed between the upper caliper body 2 and the lower caliper body 3, a fixing rod 4 is arranged on the upper caliper body 2, an opening for the fixing rod 4 to pass through is opened on the lower caliper body 3, a positioning assembly 5 for positioning the two caliper bodies is arranged on the fixing rod 4, a brake pad 6 for braking is arranged on the upper caliper body 2 and the lower caliper body 3, and the rear of the caliper as a whole 1 A fixing part 7 is provided at the end, and two brake pads 6 are both mounted on the fixing part 7. A positioning spring 8 is provided on the fixing part 7 and relative to the two brake pads 6. A piston return structure 9 connected to the brake pads 6 is provided in the upper caliper body 2 and the lower caliper body 3. The piston return structure 9 includes a caliper piston 10, a movable rod 11 and a reset spring 12. The upper caliper body 2 has an activity space for the caliper piston 10 to move. A sealing part 13 is provided on the upper caliper body 2 and relative to the upper end of the brake pads 6. The movable rod 11 extends out of the activity space and is connected to the brake pads 6.

[0019] Preferably, the hydraulic oil applies pressure to the caliper piston 10, causing it to move downward, and the movable rod 11 drives the brake pad 6 to move toward the brake disc, compressing the return spring 12. When the hydraulic oil returns, the return spring 12 rebounds, causing the caliper piston to rebound, controlling the brake pad 6 to return faster, thereby achieving a better return effect for the brake caliper.

[0020] To further explain, the positioning assembly 5 includes a positioning piece 14 and a connecting spring 15. The fixing rod 4 is provided with a mounting groove for installing the positioning assembly 5. One end of the positioning piece 14 extends out of the mounting groove and is used to position the lower caliper body 3. One end of the connecting spring 15 is connected to the fixing rod 4, and the other end of the connecting spring 15 is fixedly connected to the other end of the positioning piece 14 extending into the mounting groove.

[0021] To elaborate further, for the installation of the brake caliper, the fixing rod 4 of the upper caliper body 2 is matched with the opening of the lower caliper body 3, the positioning piece 14 is inserted into the mounting groove of the fixing rod 4, the connecting spring 15 is compressed, the fixing rod 4 is inserted into the opening, and extends out of the lower caliper body 3, the connecting spring 15 rebounds, the positioning piece 14 is extended out of the mounting groove of the fixing rod 4 and abuts against the bottom end of the lower caliper body 3, thereby fixing the upper caliper body 2 and the lower caliper body 3. When it needs to be disassembled, the positioning piece 14 is inserted into the mounting groove of the fixing rod 4, and the upper caliper body 2 can be removed from the lower caliper body 3.

[0022] To be more specific, there are two movable spaces on the upper caliper body 2, and each movable space has a piston return structure 9 connected to the brake.

[0023] To be more specific, the upper caliper body 2 is provided with a hydraulic oil pipeline 16 for the hydraulic oil to enter, and both the upper caliper body 2 and the lower caliper body 3 are provided with oil inlet pipelines for the hydraulic oil to enter their activity spaces, and the lower caliper body 3 is provided with an oil inlet port 17, and the oil inlet pipeline of the lower caliper body 3 is connected with the oil inlet pipeline of the upper caliper body 2. When the brake caliper is working, the hydraulic oil enters the upper caliper body 2 from the hydraulic oil pipeline 16 and applies pressure to the caliper piston 10. At the same time, the hydraulic oil enters the oil inlet pipeline of the upper caliper body 2 and enters the oil inlet pipeline of the lower caliper body 3 through the oil inlet port 17, applying pressure to the caliper piston 10 in the lower caliper body 3, thereby controlling the brake pad 6 to brake.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
