Description

Technical Field

[0001] This utility model relates to the field of automotive brake caliper technology, specifically a high-safety automotive brake caliper. Background Technology

[0002] The brake caliper is the core component of a disc brake system. Its main function is to use hydraulic pressure to push the brake pads against the brake disc to achieve vehicle deceleration or braking. Inside the caliper is a piston. When the brake fluid pressure acts on the piston, it pushes the brake pads to clamp the brake disc, and the vehicle's kinetic energy is converted into heat energy through friction.

[0003] For example, the authorization announcement number "CN219529650U" describes a type of automotive brake caliper. It uses the elastic force generated by the compression of the return spring to ensure the reset of the two sets of mounting plates, thus preventing the brake disc from locking up. Existing automotive brake calipers use hydraulic power to push the two calipers together to clamp the brake disc in the middle to achieve the purpose of braking. However, the friction between the brake caliper and the side wall of the brake disc for a long time will cause serious wear. Under normal use, the driver needs to check and replace the brake disc every once in a while. However, forgetting to replace the worn brake disc will result in the brake caliper clamping force being limited when the car is traveling at high speed, which will not be able to reduce the speed of the car quickly and may easily lead to dangerous accidents.

[0004] Meanwhile, existing automotive brake calipers rely entirely on hydraulically driven pistons on both sides to provide the power for the caliper to engage. However, in actual use, there may be leaks or blockages in the hydraulic lines. In such cases, if the brake pedal is pressed, the brake caliper may not be able to engage in time to brake. The lack of an additional backup emergency braking mechanism affects the safety of using automotive brake calipers. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing automotive brake calipers, such as the limited clamping force of the brake calipers when the worn brake discs are not replaced, which leads to the inability to quickly reduce the speed of the vehicle at high speeds, and the lack of an additional backup emergency braking mechanism, which affects the safety of the use of automotive brake calipers. Therefore, this invention proposes a safer automotive brake caliper.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Design a high-safety automotive brake caliper, including an automotive brake disc, a connecting shaft, and a brake caliper housing. The connecting shaft is fixedly connected to the center of the automotive brake disc. The outer wall of the brake caliper housing is provided with a noise collection and inspection brake disc structure. The inner side of the brake caliper housing is provided with a hydraulic braking clamping structure. The outer surface of the automotive brake disc is provided with a spare vertical hydraulic locking structure.

[0007] Preferably, the noise recording and inspection brake disc structure includes a power supply box and connecting pieces. The two connecting pieces are fixedly connected to both ends of the outer wall of the brake caliper housing. A small recorder is fixedly installed on the outer side of the two connecting pieces. The power supply box is fixedly installed on the top of the outer wall of the brake caliper housing. A wire is fixedly connected to one side of the two power supply boxes.

[0008] This power supply box can power a small recorder along the wires. When the car's brake discs are not severely worn, the brake calipers on both sides gripping the outer wall of the brake disc will produce a regular, brief sound. However, when the brake discs are severely worn, the small recorder will record noisy, irregular, and harsh sounds from the brake discs. Therefore, by listening to the recordings from the small recorder, drivers can indirectly determine whether the car's brake discs are worn to the point of needing replacement. This allows for a quick and timely assessment of the brake discs' working condition, preventing many dangerous driving accidents.

[0009] Preferably, the two power supply boxes are electrically connected to the small recorders via wires, and the front ends of the two small recorders are positioned opposite to the outer wall of the car brake disc.

[0010] Preferably, the hydraulic brake clamping structure includes connecting bolts and oil inlets. Multiple connecting bolts are threaded onto the outer sides of two brake caliper housings. Locking nuts are threaded onto both ends of the multiple connecting bolts. Two oil inlets are fixedly installed on the outer sides of the brake caliper housings. Pistons are fixedly connected inside the two oil inlets. Friction brake pads are fixedly connected to the other ends of the multiple pistons. Hydraulic pipes are fixedly connected to the outer sides of the two oil inlets.

[0011] This feature connects two separate brake caliper housings together using a locking nut at the end of the connecting bolt. The oil inlet allows hydraulic oil injected into the hydraulic pipe to be delivered to the piston. Multiple pistons on both sides push and squeeze the opposing friction brake pads inward, causing them to press against the outer wall of the car brake disc, thus achieving the purpose of locking the brakes. The friction brake pads are made of highly wear-resistant carbon fiber material. Similarly, when the hydraulic oil is discharged in the reverse direction along the hydraulic pipe, the piston will not press against the outer side of the car brake disc.

[0012] Preferably, the inner walls of the two friction brake pads are slidably connected to the outer walls of the vehicle brake disc, and the ends of the two hydraulic pipes are connected to the piston through oil inlets.

[0013] Preferably, the backup vertical hydraulic locking structure includes a locking groove and a hydraulic cylinder. The locking groove is movably installed on the top of the outer wall of the automobile brake disc, and a push plate is fixedly installed on the top of the locking groove. The hydraulic cylinder is fixedly connected to the top of the push plate.

[0014] This hydraulic cylinder is connected to the corresponding hydraulic equipment in the vehicle via a backup hydraulic pipeline. When the brakes fail or become insensitive, the driver can activate the hydraulic cylinder from inside the cab using a backup power source. The hydraulic cylinder quickly presses the push plate downwards, and the push plate presses the U-shaped locking groove tightly against the top of the outer wall of the vehicle's brake disc. This is an additional backup emergency braking structure that can be temporarily used for braking when the brake caliper malfunctions, ensuring the safety of the vehicle's brake caliper operation.

[0015] Preferably, the hydraulic cylinder is fixedly installed on both sides of the inner wall of the two brake caliper housings.

[0016] The present invention proposes a highly safe automotive brake caliper with the following advantages: the power box can supply power to a small recorder along the wires. When the brake disc is not severely worn, the brake calipers on both sides will produce a regular, short sound when they grip the outer wall of the brake disc. However, when the brake disc is severely worn, the small recorder will record a noisy, irregular, and harsh sound from the brake disc. Therefore, the driver can indirectly judge whether the brake disc is worn to the point of needing replacement by playing the sound recording from the small recorder. This allows for timely and rapid assessment of the brake disc's working condition, and timely handling can prevent many dangerous driving accidents.

[0017] The hydraulic cylinder is connected to the corresponding hydraulic equipment in the car through a backup hydraulic pipeline. When the brakes fail or become insensitive, the driver can start the hydraulic cylinder from inside the cab using the backup power supply. The hydraulic cylinder quickly presses the push plate downwards, and the push plate presses the U-shaped locking groove tightly against the top of the outer wall of the car's brake disc. This is an extra backup emergency braking structure that can be temporarily used for braking when the brake caliper malfunctions, ensuring the safety of the car's brake caliper operation.

[0020] The present invention will be further described below with reference to the accompanying drawings: Example:

[0021] Please see Figure 1-6 In this embodiment, a high-safety automotive brake caliper includes an automotive brake disc 1, a connecting shaft 2, and a brake caliper housing 3. The automotive brake disc 1 is made of high-strength, wear-resistant cast iron. The connecting shaft 2 is used to connect the automotive brake disc 1 and the automotive wheel axle assembly. The connecting shaft 2 is fixedly connected to the center of the automotive brake disc 1. The outer wall of the brake caliper housing 3 is provided with a noise-collecting and inspection brake disc structure 4. The brake caliper housing 3 is made of relatively hard and wear-resistant metal steel. Two brake caliper housings 3 are arranged opposite each other, clamping the automotive brake disc 1 on the inner side at the middle position. The inner side of the brake caliper housing 3 is provided with a hydraulic brake clamping structure 5. A spare vertical hydraulic locking structure 6 is provided on the upper surface of the automotive brake disc 1.

[0022] The noise recording and inspection brake disc structure 4 includes a power supply box 41 and connecting plates 44. Two connecting plates 44 are fixedly connected to both ends of the outer wall of the brake caliper housing 3. The connecting plates 44 are made of stainless steel sheets welded to both ends of the brake caliper housing 3. A small recorder 43 that can record the sound of the car brake disc 1 is installed on the outside of the connecting plates 44. The small recorder 43 is fixedly installed on the outside of the two connecting plates 44. The power supply box 41 is fixedly installed on the top of the outer wall of the brake caliper housing 3. The power supply box 41 can supply power to the small recorder 43 along the wire 42. When the car brake disc 1 is not severely worn, the brake calipers on both sides will produce a regular and short sound when they grip the outer wall of the car brake disc 1. However, when the brake disc is severely worn, the small recorder 43 will record a noisy and irregular screeching sound from the brake disc. Therefore, the driver can indirectly judge whether the car brake disc 1 is worn to the point of needing replacement by playing the sound recording of the small recorder 43. Wires 42 are fixedly connected to one side of the two power supply boxes 41.

[0023] Two power supply boxes 41 are electrically connected to small recorders 43 via wires 42. The front ends of the two small recorders 43 are positioned opposite to the outer wall of the car brake disc 1.

[0024] The hydraulic brake clamping structure 5 includes connecting bolts 52 and oil inlets 53. Multiple connecting bolts 52 are threaded onto the outer sides of two brake caliper housings 3. Locking nuts 51 at the ends of the connecting bolts 52 connect the two separate brake caliper housings together. Locking nuts 51 are threaded onto both ends of the multiple connecting bolts 52. Two oil inlets 53 are fixedly installed on the outer sides of the brake caliper housings 3. The oil inlets 53 can deliver hydraulic oil injected into the hydraulic pipe 56 to the piston 54. Multiple pistons 54 on both sides push and compress the opposing friction brake pads 55 inwards. The brake pads are pressed against the outer wall of the car brake disc 1 to achieve the purpose of clamping the brake. The two oil inlets 53 are fixedly connected to the pistons 54. The other end of the pistons 54 is fixedly connected to the friction brake pads 55. The friction brake pads 55 are made of highly wear-resistant carbon fiber material. Similarly, when the hydraulic oil is discharged in the reverse direction along the hydraulic pipe 56, the pistons 54 will not press against the outside of the car brake disc 1. The two oil inlets 53 are fixedly connected to the outside of the hydraulic pipe 56. The inner walls of the two friction brake pads 55 are slidably connected to both sides of the outer wall of the car brake disc 1. The ends of the two hydraulic pipes 56 are connected to the pistons 54 through the oil inlets 53.

[0025] The backup vertical hydraulic locking structure 6 includes a locking groove 63 and a hydraulic cylinder 61. The locking groove 63 is movably installed on the top of the outer wall of the car brake disc 1, and the hydraulic cylinder 61 is vertically installed on the top of the inner wall of the brake caliper housing 3. The hydraulic cylinder 61 is connected to the corresponding hydraulic equipment of the car through a backup hydraulic pipeline. When the brakes fail or become insensitive, the driver can start the hydraulic cylinder 61 from inside the driver's cab using a backup power supply. The hydraulic cylinder 61 quickly presses the push plate 62 downward, and the push plate 62 presses the U-shaped locking groove 63 tightly against the top of the outer wall of the car brake disc 1. This is an additional backup emergency braking structure that can be used temporarily for braking when the brake caliper malfunctions. Because it is a temporary structure, its durability is relatively lower than that of the friction brake pads 55. The top of the locking groove 63 is fixedly installed with the push plate 62, and the hydraulic cylinder 61 is fixedly connected to the top of the push plate 62. The hydraulic cylinder 61 is fixedly installed on both sides of the inner wall of the two brake caliper housings 3.

[0026] Working principle: High-safety automotive brake calipers are installed near the wheel hubs of a car. Two brake calipers are fitted over the outside of the brake disc used for braking. Hydraulic pressure pushes the brake pads to rub against the brake disc, thereby slowing down or braking the vehicle. Inside the caliper is a piston. When the brake fluid pressure acts on the piston, it pushes the brake pads to clamp the brake disc, converting the vehicle's kinetic energy into heat energy through friction. The car brake disc 1 is made of high-strength and wear-resistant cast iron. The connecting shaft 2 is used to connect the car brake disc 1 and the car wheel axle assembly. The brake caliper housing 3 is made of relatively hard and wear-resistant metal steel. The two brake caliper housings 3 are arranged opposite each other, clamping the car brake disc 1 on the inside in the middle position. The connecting piece 44 is made of stainless steel sheet welded to both ends of the brake caliper housing 3. A small recorder 43 that can record the sound of the car brake disc 1 is installed on the outside of the connecting piece 44. The power box 41 can supply power to the small recorder 43 along the wire 42. When the car brake disc 1 is not severely worn, the brake calipers on both sides will produce a regular and short sound when they grip the outer wall of the car brake disc 1. However, when the brake disc is severely worn, the small recorder 43 will record a noisy and irregular screeching sound from the brake disc. Therefore, the driver can judge whether the car brake disc 1 is worn to the point of needing to be replaced by playing the sound recording of the small recorder 43. The driver can quickly judge the working condition of the brake disc and deal with it in time, which can avoid many dangerous driving accidents. The connecting bolt 52 and the locking nut 51 at the end can connect the two separate brake caliper housings together. The oil inlet 53 can deliver the hydraulic oil injected inside the hydraulic pipe 56 to the piston 54. Multiple pistons 54 on both sides push and squeeze the opposing friction brake pads 55 inward. The opposing friction brake pads 55 press against the outer wall of the car brake disc 1, which can achieve the purpose of locking the brake. The friction brake pads 55 are made of highly wear-resistant carbon fiber material. Similarly, when the hydraulic oil is discharged in the reverse direction along the hydraulic pipe 56, the piston 54 will not press against the outside of the car brake disc 1. Hydraulic cylinder 61 is connected to the corresponding hydraulic equipment of the car through a spare hydraulic pipeline. When the brakes fail or become insensitive, the driver can start hydraulic cylinder 61 from inside the cab using a spare power source. Hydraulic cylinder 61 quickly presses push plate 62 downwards, and push plate 62 presses the U-shaped locking groove 63 tightly against the top of the outer wall of the car brake disc 1. This is an additional backup emergency braking structure that can be used temporarily for braking when the brake caliper malfunctions. Because it is a temporary structure, its durability is relatively lower than that of friction brake pads 55.
