Description

Technical Field

[0001] This utility model relates to the field of automotive brake caliper technology with high maintenance efficiency, specifically an automotive brake caliper with high maintenance efficiency. Background Technology

[0002] The brake caliper is the core component of the disc brake system. Its main function is to press the brake pads against the rotating brake disc through mechanical or hydraulic force, and use friction to slow down or stop the vehicle.

[0003] For example, a type of automotive brake caliper with authorization announcement number "CN109050496B" effectively controls the wear of brake pads and brake discs, thereby extending their lifespan. During braking, while the brake pads contact the brake disc, the side of the second cut on the equalizer contacts and rubs against the brake disc, thus balancing the force on both ends of the brake disc. This avoids damage to the brake disc caused by long-term unilateral force, delays the replacement cycle of the brake disc, and reduces the maintenance cost of the automotive braking system. However, in the use of automotive brake calipers, the braking signal must pass through multiple transmission links such as "hydraulic column → rack → gear → worm → worm wheel → tapered thread drive wheel → star wheel → brake pad" before being transmitted to the brake pads. The transmission time is too long, and an excessively long transmission chain may slow down the braking response speed, especially in emergency braking scenarios, reducing the braking effect of the automotive brake caliper. At the same time, the complex transmission structure reduces the maintenance efficiency of the automotive brake caliper. Utility Model Content

[0004] The purpose of this invention is to solve the problems of reduced braking effect of automotive brake calipers and reduced maintenance efficiency of automotive brake calipers due to complex transmission structures, and to propose an automotive brake caliper with high maintenance efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a high-maintenance-efficiency automotive brake caliper, including a bracket and straight plates. The top left and right ends of the bracket are fixedly connected to the bottom of two straight plates, respectively. A control structure is connected to the outer wall of the bracket, and spring-loaded structures are connected to the left and right sides of the inner wall of the bracket, respectively. The outer wall of the control structure is threaded.

[0006] This design features straight plates on both the left and right sides of the top of the bracket. These two plates can be fitted with the mounting points on the left and right sides of the car to complete the installation with bolts.

[0007] Preferably, the control structure includes a bend and a vertical tube. The outer wall of the bend is fixedly connected to the outer circular opening of the support. The end of the outer wall of the bend is connected to the lower part of the outer wall of the vertical tube. The bottom end of the bend is connected to a straight cylinder. A protruding rod is slidably connected to the inner wall of the straight cylinder. A brake pad is fixedly connected to the inner side of the protruding rod. The outer sides of the two straight cylinders are respectively fixedly connected to the left and right sides of the inner wall of the support.

[0008] This design allows the circular plate at the outer end of the protruding rod to fit snugly against the inner wall of the straight cylinder, preventing leakage to the outer wall of the protruding rod.

[0009] Preferably, the outer wall of the vertical tube is threaded.

[0010] Preferably, the outer wall of the thread is threaded with a vertical cylinder.

[0011] With this design, the vertical cylinder rotates up and down through the threads on the outer wall of the vertical tube under stress, and the internal space of the vertical cylinder can be fitted with the outer wall of the inserted oil pipe to achieve the insertion and fixation of the oil pipe and the vertical tube.

[0012] Preferably, the spring-loaded structure includes sleeves and crossbars, with the outer sides of the multiple sleeves respectively fixed to the left and right sides of the inner wall of the bracket, the inner wall of the sleeves slidably connected to the outer wall of the crossbar, and a spring sleeved on the outer wall of the sleeves.

[0013] This design allows the crossbar to slide left and right along the inner wall of the sleeve when subjected to force, thus limiting the spring and preventing it from bending.

[0014] Preferably, a damping pad is fixedly connected to the outer wall end of the sleeve, the inner side of the crossbar is fixedly connected to the outer wall of the brake pad, and the outer wall of the damping pad is fixedly connected to the inner wall of the bracket.

[0015] This feature allows the damping pad to cushion the spring's elasticity, preventing the brake pads from shaking due to the spring's reciprocating rebound force.

[0016] Preferably, the two ends of the spring are fixedly connected to the outer wall of the damping pad and the outer wall of the brake pad, respectively.

[0017] The present invention proposes a high-maintenance automotive brake caliper with the following advantages: The control structure allows hydraulic fluid to be delivered from the hydraulic hose into the vertical pipe, then through the vertical pipe to the curved pipes on both sides. The fluid then enters the straight cylinder, where it presses against the cam, causing it to move inwards along the inner wall of the straight cylinder. This moving cam carries the brake pad inwards, bringing the outer wall of the brake pad into contact with the outer wall of the automotive brake pad, thus completing the braking action. This design changes the original complex transmission method, accelerates braking speed, and improves the braking effect of the automotive brake caliper. Simultaneously, the simplified transmission structure improves the maintenance efficiency of the automotive brake caliper. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-5 In this embodiment, a high-maintenance automotive brake caliper includes a bracket 1 and a straight plate 4. The top left and right ends of the bracket 1 are fixedly connected to the bottom of the two straight plates 4 respectively. The outer walls of the two straight plates 4 are respectively machined with multiple round openings, and the inside of the round openings is machined with threads. The outer wall of the bracket 1 is connected to a control structure 2. The left and right sides of the inner wall of the bracket 1 are respectively connected to a spring structure 3. The outer wall of the control structure 2 is machined with threads 5.

[0021] The control structure 2 includes a bend 201 and a vertical pipe 202. The outer wall of the bend 201 is fixedly connected to the outer wall of the bracket 1. The end of the outer wall of the bend 201 is connected to the lower part of the outer wall of the vertical pipe 202. The bottom end of the bend 201 is connected to a straight cylinder 203. A protruding rod 204 is slidably connected to the inner wall of the straight cylinder 203. The protruding rod 204 slides left and right through the inner wall of the straight cylinder 203 under force. A brake pad 205 is fixedly connected to the inner side of the protruding rod 204. The outer sides of the two straight cylinders 203 are fixedly connected to the left and right sides of the inner wall of the bracket 1, respectively. The outer wall of the vertical pipe 202 is machined with threads 5. The oil is fed into the vertical pipe 202 through the car oil pipe in the control structure 2, and then the oil is delivered to the bent pipes 201 on both sides through the vertical pipe 202. Then the oil enters the straight cylinder 203, where the oil squeezes the convex rod 204, causing the convex rod 204 to move inward on the inner wall of the straight cylinder 203. The moving convex rod 204 carries the brake pad 205 inward, so that the outer wall of the brake pad 205 is pressed against the outer wall of the car brake pad, completing the car braking work. This changes the original complex transmission form, speeds up the braking speed, and improves the braking effect of the car brake caliper. At the same time, the simplified transmission structure improves the maintenance efficiency of the car brake caliper.

[0022] The outer wall of the thread 5 is threaded with a vertical cylinder 6. The spring-loaded structure 3 includes a sleeve 301 and a crossbar 302. The outer sides of multiple sleeves 301 are fixedly connected to the left and right sides of the inner wall of the bracket 1, respectively. The inner wall of the sleeve 301 is slidably connected to the outer wall of the crossbar 302. The crossbar 302 slides left and right through the inner wall of the sleeve 301 under force. A spring 303 is sleeved on the outer wall of the sleeve 301. A damping pad 7 is fixedly connected to the end of the outer wall of the sleeve 301. The damping pad 7 can eliminate the spring-loaded force of the spring 303. The inner side of the crossbar 302 is fixedly connected to the outer wall of the brake pad 205. The outer wall of the damping pad 7 is fixedly connected to the inner wall of the bracket 1. The two ends of the spring 303 are fixedly connected to the outer wall of the damping pad 7 and the outer wall of the brake pad 205, respectively. After the brake pad 205 moves inward under force, it rebounds through the spring-loaded force of the spring 303.

[0023] Working principle: Brake installation of automotive brake calipers: Insert the two brake pads 205 inside the bracket 1 into the outer wall of the car brake pads. At this time, the two brake pads are adjacent to the car brake pads. At this time, there are straight plates 4 on the left and right sides of the top of the bracket 1. One of the straight plates 4 will fit against the car mounting location. Then, the bolt passes through the round opening on the outer wall of the straight plate 4 and is threaded into the round opening of the car mounting location. Then, the end of the car hydraulic oil pipe is inserted into the outer wall of the vertical pipe 202. Then, the vertical cylinder 6 is rotated upward with the thread 5 so that the inner wall of the vertical cylinder 6 fits into the outer wall of the hydraulic oil pipe, completing the fixation of the vertical cylinder 6 and the oil pipe, and completing the installation of the car brake caliper.

[0024] Braking operation of car brake calipers: The car's oil pipe delivers oil into the vertical pipe 202, and then through the vertical pipe 202 to the curved pipes 201 on both sides. Next, the oil enters the straight cylinder 203, where it squeezes the convex rod 204, causing it to move inward on the inner wall of the straight cylinder 203. The moving convex rod 204 carries the brake pad 205 inward, causing the outer wall of the brake pad 205 to press against the outer wall of the car's brake pads, thus completing the car's braking operation. The inward movement of the brake pad 205 stretches the spring 303. Then, the oil pipe stops delivering oil, and the oil loses pressure. At this point, the spring 303 provides a rebound force, carrying the brake pad 205 outward, causing it to detach from the surface of the car's brake pads. The crossbar 302 slides outward through the inner wall of the sleeve 301. Simultaneously, the damping pad 7 cushions the spring force of the spring 303, preventing the spring 303 from reciprocating.

[0025] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
