Description

Technical Field

[0001] The present application relates to the technical field of vehicle braking, and in particular to a brake locking device and a brake caliper assembly. Background Art

[0002] Brake calipers are an important part of modern automobile braking systems. They use electronic control to achieve parking brakes, integrating the temporary braking of traditional handbrakes with the long-term braking function after parking, thus improving driving convenience and safety.

[0003] When the driver needs to stop the car, he presses the electronic handbrake button (or automatically triggers the AUTO HOLD function). After receiving the signal, the ECU controls the motor to start and drives the brake pads in the brake caliper to clamp the brake disc through the transmission mechanism. The friction between the brake pads and the brake disc generates braking force, which stops the vehicle and keeps it stationary.

[0004] However, when a vehicle is parked on a road with a relatively large slope, due to the large inclination angle of the vehicle and the weight of the vehicle itself, the existing parking brake may not be sufficient to meet the parking requirements during the above parking, resulting in accidental vehicle slipping. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of this application is to provide a brake locking device and a brake caliper assembly, which are used to solve the technical problem that when parking is required on a very inclined slope, the ordinary parking brake force may not be sufficient to completely prevent the vehicle from sliding down.

[0006] The above-mentioned purpose of the present application is achieved through the following technical solutions: a brake locking device, including a brake device arranged on a brake disc, the brake device including a drive housing, an active brake device and a passive brake device, the active brake device is arranged in the drive housing, and a linkage structure for driving the passive drive device is arranged in the drive housing and between the active brake device.

[0007] Furthermore, the passive braking device includes a pair of linkage rods arranged on the outside of the driving shell, each of the linkage rods has a groove at the end, a driving inner block is rotatably arranged in the groove, a driving rod is fixedly arranged at the other end of the driving inner block, a second brake plate is arranged at the bottom of the driving rod, a return spring is arranged at one end of the driving inner block close to the driving shell, a connecting rod fixedly connected to the driving shell is arranged at the upper end of the return spring, a sliding device is arranged at the end of the connecting rod, and the edge of the driving inner block abuts against the sliding device.

[0008] By adopting the above technical solution, when displacement still occurs after the active braking device is started, the linkage rod will be pushed through the linkage structure, thereby rotating the driving inner block on the end of the linkage rod, and the driving rod on the driving inner block will be driven to move by abutting against the sliding device, thereby driving the second brake plate to be squeezed inward, so that the second brake plate will squeeze the brake disc, thereby performing secondary braking.

[0009] Furthermore, the active braking device includes an active brake block and first brake plates on both sides. The active brake block is hollow inside, and brake rods are fixedly provided on the first brake plates. The brake rods are slidably connected to the active brake block, and meshing teeth are fixedly provided on the two brake rods. A linkage column is rotatably provided inside the active brake block, and a linkage gear is fixedly provided on the linkage column. The linkage gear is meshed with the brake rod, and an extrusion cylinder for driving the first brake plate is installed on the active brake block, and the linkage rod is fixedly connected to the active brake block.

[0010] By adopting the above technical solution, the brake lever on one side is driven by the extrusion cylinder, and the teeth on the rear brake lever are pushed to engage with the linkage gear on the linkage column, thereby driving the other brake lever, so that the first brake plates on both sides are squeezed at the same time to complete active braking.

[0011] Furthermore, the linkage structure includes linkage springs arranged at both ends of the active brake block, and a group of linkage springs are arranged at both ends of the active brake block. One end of the linkage spring is fixedly connected to the active brake block, and the other end is fixedly connected to the drive housing.

[0012] By adopting the above technical solution and setting the linkage spring, after the active brake block moves, it will first pass through the force-bearing linkage spring, thereby driving the linkage rods on both sides of the active brake block to drive the passive braking device. The linkage spring used in this application is customized according to the gravity of the vehicle body.

[0013] Furthermore, the sliding device includes a rotating column fixedly connected to the end of the connecting rod, a sliding block is fixedly arranged on the rotating column, a matching sliding groove is opened on the edge of the driving inner block, and the sliding block is slidably connected in the sliding groove.

[0014] By adopting the above technical solution, when the driving inner block is pushed by the linkage rod, it will slide along the sliding groove, thereby driving the driving rod on the other side and the second brake plate.

[0015] Furthermore, connecting blocks are fixedly provided at both ends of the return spring, and connecting grooves matching the connecting blocks are evenly provided on the driving inner block and the driving outer shell, and the connecting blocks at both ends are plugged into the connecting grooves.

[0016] By adopting the above technical solution, considering that the reset spring will be squeezed each time passive braking occurs, in order to facilitate replacement, the reset spring is set in a plug-in manner in the present application. When replacing, the reset spring can be removed by squeezing it. The installation is also to squeeze the reset spring and plug the connecting blocks on both sides into the connecting grooves.

[0017] Furthermore, a rubber layer is fixedly provided around the connecting block.

[0018] By adopting the above technical solution, the stability of the connecting block and the connecting groove is improved.

[0019] Furthermore, the passive braking device is provided at both ends of the driving housing.

[0020] By adopting the above technical solution, the vehicle can be started and braked regardless of whether the vehicle body is tilted toward the front or rear end.

[0021] Furthermore, both of the second brake plates are provided with a limiting structure for enhancing the braking effect of the first brake plate, the limiting structure includes a plurality of limiting columns and a plurality of limiting holes opened on the brake disc, the limiting columns are threadedly connected to the second brake plate, and the plurality of limiting columns are distributed in an arc-shaped array on the second brake plate.

[0022] By adopting the above technical solution, although the setting of the passive braking device allows the passive braking device to be immediately activated when the active braking device is displaced or insufficient to completely brake, thereby ensuring a more reliable braking effect, the braking is also achieved by friction, and there may be a situation where the passive braking device cannot brake the brake disc. The setting of the limiting structure solves this technical problem. When the extrusion force of the second brake plate is insufficient to brake the brake disc, the continued rotation of the brake disc will cause the limiting column to be inserted into the limiting hole, so that the limiting column limits the rotation of the brake disc, thereby preventing the vehicle from sliding down, further improving the braking effect of the passive braking device.

[0023] Furthermore, a mud guard for blocking mud is arranged on the outside of the brake disc, a steering knuckle for driving the steering of the vehicle is arranged in the middle of the brake disc (3), a connecting piece is arranged between the steering knuckle and the extrusion cylinder for fixed installation, and an integrated shell for protecting the active braking device and the passive braking device is arranged on the upper end of the mud guard.

[0024] By adopting the above technical solution, the mud guard in this application is installed among other parts of the car. The function of the mud guard is to block the splashing of mud on the ground during driving, thereby preventing the mud from adhering to the brake disc and reducing the braking effect. The one-piece shell is set to protect the active braking device and the passive braking device.

[0025] Furthermore, a brake caliper assembly is applicable to a brake locking device described in any one of the above technical solutions, including a controller and an actuator. The controller drives the actuator after receiving a parking signal, and the brake device performs parking brakes on the vehicle.

[0026] By adopting the above technical solution, the actuator is the car handbrake button. When parking brake is required, the actuator is started, and the electronic control unit in the controller transmits a signal to squeeze the cylinder, thereby pushing the brake lever on one side. After pushing, the teeth on the rear brake lever will engage with the linkage gear on the linkage column, thereby driving the other brake lever, so that the first brake plates on both sides are squeezed at the same time to complete active braking. Correspondingly, when the parking brake is canceled, the actuator sends a signal to the electronic control unit in the controller, and the squeezing cylinder will be recovered, thereby opening the first brake plates at both ends at the same time to complete the cancellation of the brake.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. By combining the active braking device and the passive braking device, the passive braking device can be activated immediately even when the active braking device is displaced or insufficient for complete braking, ensuring a more reliable braking effect. The friction block on the second brake plate is made of a material with a high friction coefficient (such as white ceramic fiber), which significantly improves the braking performance of the brake disc and shortens the braking distance.

[0028] 2. Whether the vehicle body is tilted forward or backward, the passive braking device is set at both ends of the drive housing, which can respond quickly and perform secondary braking to prevent the vehicle from accidentally sliding due to the slope. The plug-in design of the return spring is easy to replace, reducing the risk of brake failure caused by spring aging or damage, and improving the long-term stability and safety of the system.

[0029] 3. The system realizes intelligent control through the electronic control unit. Users can easily complete the parking brake and brake cancellation operations by simply operating the actuator (such as the car handbrake button), which improves the convenience and comfort of driving. The electronic control unit can respond and execute instructions quickly, ensuring the timeliness and accuracy of braking.

[0030] 4. The ingenious design of the active brake block and linkage rod enables the force to be transmitted to the passive brake device through the linkage spring when the active brake device is working, thus realizing the automatic triggering of the secondary brake. The cooperation between the sliding device and the driving inner block makes the driving rod move more smoothly, reducing the noise and vibration during the braking process.

[0031] 5. The plug-in design of the return spring makes it easy to replace when necessary, reducing maintenance time and cost. The rubber layer around the connection block not only improves the stability of the connection, but also reduces the wear caused by vibration and friction to a certain extent.

[0032] 6. The semi-metallic first brake plate and white ceramic fiber friction block not only ensure the braking performance, but also take into account the environmental protection and durability of the materials, reducing the dust and noise pollution generated during braking.

[0036] When displacement still occurs after the active braking device is activated, the linkage rod 21 will be pushed through the linkage structure, thereby rotating the driving inner block 22 on the end of the linkage rod 21, and the driving rod 23 on the driving inner block 22 will be moved by abutting against the sliding device, thereby driving the second brake plate 24 to be squeezed inward, so that the second brake plate 24 will squeeze the brake disc 3, thereby performing secondary braking.

[0037] In this embodiment, the active brake device includes an active brake block 1 and first brake plates 12 on both sides. The active brake block 1 is hollow inside. Brake rods 13 are fixedly arranged on the first brake plates 12. The brake rods 13 are slidably connected to the active brake block 1. Meshing teeth are fixedly arranged on the two brake rods 13. A linkage column 15 is rotatably arranged inside the active brake block 1. A linkage gear 14 is fixedly arranged on the linkage column 15. The linkage gear 14 is meshed with the brake rod 13. An extrusion cylinder 30 for driving the first brake plate 12 is fixedly arranged on the active brake block 1. The linkage rod 21 is fixedly connected to the active brake block 1. The extrusion cylinder 30 drives the brake rod 13 on one side, and the teeth on the rear brake rod 13 are pushed to mesh with the linkage gear 14 on the linkage column 15, thereby driving the other brake rod 13, so that the first brake plates 12 on both sides are squeezed at the same time to complete the active braking.

[0038] In this embodiment, the linkage structure includes linkage springs 11 arranged at both ends of the active brake block 1. A group of linkage springs 11 are arranged at both ends of the active brake block 1. One end of the linkage spring 11 is fixedly connected to the active brake block 1, and the other end is fixedly connected to the drive housing 2.

[0039] Through the setting of the linkage spring 11, after the active brake block 1 moves, it will first pass through the force-bearing linkage spring 11, thereby driving the linkage rods 21 on both sides of the active brake block 1 to drive the passive braking device. The linkage spring 11 used in this application is customized according to the gravity of the vehicle body.

[0040] In this embodiment, the sliding device includes a rotating column 28 fixedly connected to the end of the connecting rod 26, a sliding block 29 is fixedly provided on the rotating column 28, a matching sliding groove 291 is opened on the edge of the driving inner block 22, and the sliding block 29 is slidably connected in the sliding groove 291.

[0041] When the driving inner block 22 is pushed by the linkage rod 21 , it will slide along the sliding groove 291 , thereby driving the driving rod 23 and the second brake plate 24 on the other side.

[0042] In this embodiment, connecting blocks 271 are fixedly provided at both ends of the return spring 27, and connecting grooves matching the connecting blocks 271 are evenly provided on the driving inner block 22 and the driving outer shell 2, and the connecting blocks 271 at both ends are inserted into the connecting grooves.

[0043] Taking into account that the return spring 27 will be squeezed each time passive braking occurs, in order to facilitate replacement, the return spring 27 is set in a plug-in manner in the present application. When replacing, the return spring 27 can be squeezed to remove it. The installation is also done by squeezing the return spring 27 to plug the connecting blocks 271 on both sides into the connecting grooves.

[0044] In this embodiment, a rubber layer is fixedly provided around the connection block 271 to improve the stability of the connection block 271 and the connection groove.

[0045] In this embodiment, the passive braking device is arranged at both ends of the driving housing 2. Whether the vehicle body is tilted toward the front end or the rear end, the brake can be started.

[0046] In this embodiment, both second brake plates 24 are provided with a limiting structure for enhancing the braking effect of the first brake plate 12. The limiting structure includes a plurality of limiting columns 25 and a plurality of limiting holes 31 opened on the brake disc 3. The limiting columns 25 are threadedly connected to the second brake plates 24. The plurality of limiting columns 25 are distributed in an arc-shaped array on the second brake plates 24.

[0047] Although the passive braking device is set up so that when the active braking device is displaced or insufficient to completely brake, the passive braking device can be immediately activated to ensure a more reliable braking effect, the braking is also achieved by friction, and it is possible that the passive braking device cannot brake the brake disc 3. The setting of the limiting structure solves this technical problem. When the squeezing force of the second brake plate 24 is insufficient to brake the brake disc 3, the continued rotation of the brake disc 3 will cause the limiting column 25 to be inserted into the limiting hole 31, so that the limiting column 25 limits the rotation of the brake disc 3, thereby preventing the vehicle from sliding down, and further improving the braking effect of the passive braking device.

[0048] A mud guard 4 for blocking mud is arranged on the outside of the brake disc 3, a steering knuckle 5 for driving the steering of the car is arranged in the middle of the brake disc 3, a connecting piece is arranged between the steering knuckle 5 and the extrusion cylinder 30 for fixed installation, and an integrated shell 41 for protecting the active braking device and the passive braking device is arranged on the upper end of the mud guard 4. The function of the mud guard 4 is to block the splashing of mud on the ground during driving, so as to prevent the mud from adhering to the brake disc 3 and reducing the braking effect. The integrated shell 41 is arranged to protect the active braking device and the passive braking device.

[0049] The first brake plate 12 is made of semi-metal material, and the friction block is made of white ceramic fiber.

[0050] A brake caliper assembly is applicable to any one of the above technical solutions. A brake locking device comprises a controller and an actuator. The controller drives the actuator after receiving a parking signal, and the brake device performs parking brake on the vehicle.

[0051] The actuator is the car handbrake button. When parking brake is needed, the actuator is started, and the electronic control unit in the controller transmits a signal to squeeze the cylinder 30, thereby pushing the brake rod 13 on one side. After pushing, the teeth on the rear brake rod 13 will engage with the linkage gear 14 on the linkage column 15, thereby driving the other brake rod 13, so that the first brake plates 12 on both sides are squeezed at the same time to complete the active braking. Correspondingly, when the parking brake is cancelled, the actuator sends a signal to the electronic control unit in the controller, and the squeezing cylinder 30 will be recovered, thereby opening the first brake plates 12 at both ends at the same time to complete the cancellation of the brake.

[0052] Specific implementation process: The active brake device is arranged in the driving housing 2, including an active brake block 1 and first brake plates 12 on both sides. The active brake block 1 is hollow inside, and a brake rod 13 is fixed on the first brake plate 12, and the brake rod 13 is slidably connected in the active brake block 1. The two brake rods 13 are provided with teeth, which mesh with the linkage gear 14 on the linkage column 15 rotating inside the active brake block 1. The output end of the extrusion cylinder 30 is fixedly connected to the brake rod 13. By pushing the brake rod 13 on one side, the teeth are meshed with the linkage gear 14, driving the other brake rod 13, so that the first brake plates 12 on both sides squeeze the brake disc 3 at the same time, completing the active braking.

[0053] The passive braking device is connected to the outer side of the driving housing 2 through a pair of linkage rods 21. A groove is provided at the end of each linkage rod 21, in which a driving inner block 22 is rotatably arranged. A driving rod 23 is fixed to the other end of the driving inner block 22, and a second brake plate 24 is provided at the bottom of the driving rod 23. A return spring 27 is provided at the end of the driving inner block 22 close to the driving housing 2. The upper end of the return spring 27 is connected to the driving housing 2 through a connecting rod 26, and a sliding device is provided at the end of the connecting rod 26. When displacement still occurs after the active braking device is activated, the linkage structure (such as the linkage spring 11) pushes the linkage rod 21 to rotate the driving inner block 22, and drives the driving rod 23 to move by abutting the sliding device, thereby causing the second brake plate 24 to squeeze the brake disc 3 to achieve secondary braking. The return spring 27 ensures that each component returns to its initial position after the brake is released.

[0054] The sliding device includes a rotating column 28 and a sliding block 29 fixedly connected to the end of the connecting rod 26. A sliding groove 291 matching the sliding block 29 is provided on the edge of the driving inner block 22 to ensure the smooth movement of the driving inner block 22. Connecting blocks 271 are provided at both ends of the return spring 27. Connecting grooves matching the connecting blocks 271 are provided on the driving inner block 22 and the driving housing 2 to facilitate the replacement and maintenance of the return spring 27.

[0055] In addition, passive brake devices are provided at both ends of the driving housing 2, and the brake can be activated whether the vehicle body is tilted forward or backward. The first brake plate 12 is made of semi-metal material, and the friction block 25 is made of white ceramic fiber to improve the braking performance and durability.

[0056] The actuator is the car handbrake button. When parking brake is needed, the actuator is started, and the electronic control unit in the controller transmits a signal to squeeze the cylinder 30, thereby pushing the brake rod 13 on one side. After pushing, the teeth on the rear brake rod 13 will engage with the linkage gear 14 on the linkage column 15, thereby driving the other brake rod 13, so that the first brake plates 12 on both sides are squeezed at the same time to complete the active braking. Correspondingly, when the parking brake is cancelled, the actuator sends a signal to the electronic control unit in the controller, and the squeezing cylinder 30 will be recovered, thereby opening the first brake plates 12 at both ends at the same time to complete the cancellation of the brake.

[0057] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
