Description
Technical Field
[0001] This utility model relates to the field of brake caliper technology, specifically to a motor vehicle brake caliper. Background Technology
[0002] Motor vehicle brake calipers are the core actuators of disc braking systems. They are usually installed on the inside of the wheel, close to the brake disc. Their core function is to respond to the driver's command to press the brake pedal. Through the internal hydraulic piston, the brake pads are forcefully pressed against the rotating brake discs on both sides, thereby generating strong friction and converting the vehicle's kinetic energy into heat energy, thus achieving vehicle deceleration or stopping.
[0003] However, existing brake calipers are generally installed and fixed using bolts, but the bolt connection lacks auxiliary reinforcement, affecting assembly stability. Therefore, those skilled in the art have provided a motor vehicle brake caliper to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to provide a motor vehicle brake caliper to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A motor vehicle brake caliper includes a brake caliper body, an assembly connecting block fixed to the outer side of the brake caliper body, an assembly mounting hole provided inside the assembly connecting block, a stabilizing mechanism provided on the outer side of the assembly connecting block, and a reinforcing mechanism installed on the outer side of the assembly connecting block.
[0007] The stabilizing mechanism includes a fixed housing, a support spring provided on the inner top wall of the fixed housing, a support pad connected to the bottom of the support spring, a support rod fixed to the bottom of the support pad, an anti-slip pad fixed to the bottom of the support rod, a guide threaded post installed on the top of the support pad, a handle plate installed on the top of the guide threaded post, and a carbon steel nut threadedly connected to the outer side of the guide threaded post.
[0008] As a further embodiment of this utility model: the reinforcement mechanism includes a guide sleeve, the top of the guide sleeve is slidably connected to an anti-detachment slider through a groove, the top of the anti-detachment slider is fixed with a reinforcement plate, the reinforcement plate has a limit groove inside, the top of the assembly connecting block is equipped with a fixed threaded post, the top of the assembly connecting block is fixed with a threaded rod, and the outer side of the threaded rod is threaded with a metal nut.
[0009] As a further improvement of this utility model: the outer side of the metal nut is provided with anti-slip texture, and the reinforcing plate is movably sleeved on the outer side of the threaded rod.
[0010] As a further improvement of this utility model, the fixed threaded column has a through hole inside, the size of which is adapted to the size of the reinforcing plate.
[0011] As a further improvement of this utility model, the fixed outer shell and the assembly connecting block are fixedly connected.
[0012] As a further improvement of this utility model, the interior of the fixed outer shell is provided with a through hole to accommodate the movement of the guide threaded post and the support rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This device is equipped with a stabilizing mechanism. When the installation bolts slightly retract due to temperature or long-term load, it compensates through its own elastic deformation to maintain a certain preload. This compensation helps to prevent the bolt connection from having small loose gaps due to thermal stress or fatigue, keeping the connection tight. At the same time, it can provide a certain degree of flexible buffering, making the load distribution on the contact surface more uniform and smooth, thereby effectively reducing stress peaks, slowing down the possibility of micro-crack initiation and propagation, and improving the fatigue resistance of the installation area.
[0015] 2. By incorporating a reinforcement mechanism, when the assembly connecting block on the outer side of the brake caliper body is assembled, the reinforcement plate provides auxiliary reinforcement to the outer side of the mounting part of the assembly connecting block, which helps to improve the assembly stability of the brake caliper body, and is crucial for the installation of calipers that are subjected to repeated braking loads.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 In this embodiment of the utility model, a motor vehicle brake caliper includes a brake caliper body 1, an assembly connecting block 2 is fixed on the outside of the brake caliper body 1, an assembly mounting hole 3 is opened inside the assembly connecting block 2, a stabilizing mechanism 4 is provided on the outside of the assembly connecting block 2, and a reinforcing mechanism 5 is installed on the outside of the assembly connecting block 2.
[0023] The stabilizing mechanism 4 includes a fixed housing 41. A support spring 42 is installed on the inner top wall of the fixed housing 41. A support pad 43 is connected to the bottom of the support spring 42. A support rod 44 is fixed to the bottom of the support pad 43. An anti-slip pad 45 is fixed to the bottom of the support rod 44. A guide threaded post 46 is installed on the top of the guide threaded post 46. A handle plate 47 is installed on the top of the guide threaded post 46. A carbon steel nut 48 is threaded onto the outer side of the guide threaded post 46. The fixed housing 41 and the assembly connecting block 2 are fixedly connected. The interior of the fixed housing 41 has a through hole to accommodate the movement of the guide threaded post 46 and the support rod 44. When the assembly connecting block 2 on the outer side of the brake caliper body 1 is installed and fixed by bolts, the movement is facilitated by… The support spring 42 inside the fixed housing 41 provides elastic force, allowing the support pad 43 to push the support rod 44 to move. The anti-slip pad 45 at one end of the support rod 44 is in contact with the outer side of the mounting part of the brake caliper body 1. It can compensate for the slight retraction of the mounting bolt due to temperature or long-term load by its own elastic deformation, maintaining a certain preload. This compensation helps to prevent the bolt connection from having small loose gaps due to thermal stress or fatigue, keeping the connection tight. At the same time, it can provide a certain degree of flexible buffer, making the load distribution on the contact surface more uniform and smooth, thereby effectively reducing the stress peak, slowing down the possibility of micro-crack initiation and propagation, and improving the fatigue resistance of the mounting area.
[0024] In one embodiment of this utility model, the reinforcing mechanism 5 includes a guide sleeve 51. An anti-detachment slider 52 is slidably connected to the top of the guide sleeve 51 via a groove. A reinforcing plate 53 is fixed to the top of the anti-detachment slider 52. A limiting groove 54 is formed inside the reinforcing plate 53. A fixing threaded post 55 is installed on the top of the assembly connecting block 2. A threaded rod 56 is fixed to the top of the assembly connecting block 2. A metal nut 57 is threadedly connected to the outer side of the threaded rod 56. Anti-slip textures are provided on the outer side of the metal nut 57. The reinforcing plate 53 is movably sleeved on the outer side of the threaded rod 56. A through hole is formed inside the fixing threaded post 55. The size of the through hole is related to the reinforcing plate 53. The size of the reinforcing plate 53 is adapted. When the assembly connecting block 2 on the outside of the brake caliper body 1 is assembled, the guide sleeve 51 is pre-fixed to the outside of the corresponding installation part by welding. When the anti-disengagement slider 52 is pushed to move the reinforcing plate 53, the reinforcing plate 53 can pass through the fixed threaded post 55 at the top of the assembly connecting block 2. Moreover, the reinforcing plate 53 is movably sleeved on the outside of the threaded rod 56 and is threadedly connected to the threaded rod 56 with a metal nut 57. The reinforcing plate 53 provides auxiliary reinforcement to the outside of the installation part of the assembly connecting block 2, which helps to improve the assembly stability of the brake caliper body 1. This is crucial for the installation of calipers that are subjected to repeated braking loads.
[0025] The working principle of this utility model is as follows: This device is equipped with a stabilizing mechanism 4. When the mounting connecting block 2 on the outer side of the brake caliper body 1 is installed and fixed by bolts, the support spring 42 inside the fixed housing 41 provides elastic force, allowing the support pad 43 to push the support rod 44 to move. The anti-slip pad 45 at one end of the support rod 44 is in contact with the outer side of the mounting part of the brake caliper body 1. It can compensate for the slight retraction of the mounting bolt due to temperature or long-term load through its own elastic deformation, maintaining a certain preload. This compensation helps to prevent the bolt connection from having small loosening gaps due to thermal stress or fatigue, keeping the connection tight. At the same time, it can provide a certain degree of flexible buffering, making the load distribution on the contact surface more uniform and smooth. This effectively reduces peak stress, slows down the initiation and propagation of microcracks, and improves the fatigue resistance of the installation area. By setting up a reinforcement mechanism 5, when the assembly connecting block 2 on the outside of the brake caliper body 1 is assembled, the guide sleeve 51 is pre-fixed to the outside of the corresponding installation part by welding. When the anti-disengagement slider 52 is pushed to drive the reinforcement plate 53 to move, the reinforcement plate 53 can pass through the fixed threaded post 55 at the top of the assembly connecting block 2. Moreover, the reinforcement plate 53 is movably sleeved on the outside of the threaded rod 56 and is threadedly connected to the threaded rod 56 with a metal nut 57. The reinforcement plate 53 provides auxiliary reinforcement to the outside of the installation part of the assembly connecting block 2, which helps to improve the assembly stability of the brake caliper body 1. This is crucial for the installation of calipers that are subjected to repeated braking loads.
