Description

Technical Field

[0001] This application relates to the field of vehicle braking technology, and in particular to a novel mounting plate for vehicle axles. Background Technology

[0002] The automotive braking system refers to a series of specialized devices that apply a certain force to certain parts of a car (mainly the wheels) to force braking them to a certain extent.

[0003] With increasing numbers of vehicles on the road and higher speeds, the demands on braking torque during emergency braking are also rising. This places higher demands on the bolts connecting the traditional mounting plate and brake caliper. During braking, the brake disc and caliper surface rub against each other to transmit braking force. The traditional mounting plate, connected to the brake caliper by bolts, bears the braking reaction force. Therefore, when the braking torque is large, shear stress can easily be generated in the bolts, causing them to break and leading to brake failure.

[0004] Therefore, the main drawbacks of the existing technology are twofold: 1. Under conditions of large braking torque and emergency braking, the mating bolts are prone to breakage due to shear force, posing a certain risk to braking safety; 2. Currently, the assembly of brake calipers is carried out by hoisting, which is not very friendly to the assembly of brake bolts and is time-consuming and labor-intensive for workers. Utility Model Content

[0005] To address the aforementioned problems, prevent the bolts between the mounting plate and brake caliper from easily breaking under shear force, reduce braking safety hazards at high speeds, and improve braking safety, this application provides a novel mounting plate for vehicle axles.

[0006] The novel mounting plate for vehicle axles provided in this application adopts the following technical solution.

[0007] A novel mounting plate for axles includes a mounting plate body, on which mounting plate holes for connecting with an axle housing are provided. On the mounting plate body, mating surfaces perpendicular to the vehicle's driving direction are symmetrically arranged along the mounting plate holes. Mating holes for mounting brake calipers are provided on the mating surfaces along the vehicle's driving direction.

[0008] By adopting the above technical solution, mounting plate holes are opened on the mounting plate body. The opening of mounting plate holes facilitates the mounting plate body to be fitted onto the axle housing, and facilitates the installation and fixation of the mounting plate body and the axle housing. The setting of the mating surface and the opening of the mating hole facilitate the installation of the brake caliper. The mating surface is perpendicular to the vehicle's driving direction, which helps to improve the mating stability between the brake caliper and the mounting plate body. During braking, it is not easy to generate bias force. The mating hole is also opened along the vehicle's driving direction, which makes the bolts stable after bolt connection. The bolts are not easily subjected to shear force and are not easy to break. Moreover, the two mating surfaces are symmetrically arranged above and below the mounting plate hole, which helps to improve installation stability, reduce the stress on the bolts connecting the mounting plate body and the brake caliper during emergency braking, reduce the requirements for bolts, reduce braking safety hazards, meet the requirements of high-speed and emergency braking conditions, and improve braking safety.

[0009] Optionally, the mounting plate body is provided with mounting wing plates at both the top and bottom, and the mating surfaces are provided on the front and rear sides of the mounting wing plates, and the mating surfaces are precision machined.

[0010] By adopting the above technical solution, the mating surfaces are set on the front and rear sides of the mounting wing plate, and the mating surfaces are precision machined to improve surface accuracy, which is beneficial to improving the flatness of the mating surfaces, ensuring that the mating surfaces are perpendicular to the vehicle's driving direction, improving accuracy, reducing the slip component force on the brake caliper during braking, reducing the possibility of slippage between the brake caliper and the mating surface during braking, reducing or avoiding shear force on the bolts, solving the problem of bolt breakage between the mounting plate body and the brake caliper under shear force, reducing the possibility of brake failure, and improving braking safety.

[0011] Optionally, the mating hole is formed through the front and rear of the mounting wing plate.

[0012] By adopting the above technical solution, with the mating hole penetrating from front to back and aligned with the direction of vehicle travel, the brake caliper is subjected to force during braking, squeezing the mounting plate. The mounting plate experiences a reaction force. Since the mating hole penetrates from front to back and the bolt connection direction is front to back, the bolt will not receive a biased component force and therefore will not bear the reaction force during braking. The bolt experiences less force, which helps to reduce the requirements on the bolt, extend its service life, reduce the likelihood of breakage, ensure the installation stability of the brake caliper, ensure vehicle braking stability, reduce the possibility of brake failure, and improve braking safety.

[0013] Optionally, the two mounting wing plates are symmetrically arranged along the mounting plate body.

[0014] By adopting the above technical solution, the two mounting wing plates are symmetrically arranged along the mounting plate body, which helps to ensure the symmetry of the mounting plate body, making the upper and lower ends of the mounting plate body have uniform mass, making the installation of the mounting plate body more friendly and the braking force more friendly.

[0015] Optionally, the mounting plate body is provided with claws.

[0016] By adopting the above technical solution, the design of the chuck has two functions: firstly, during the processing of the mounting plate body, the chuck can be contacted for auxiliary positioning, which facilitates positioning; secondly, during assembly, the brake caliper can be hung on the chuck, which facilitates the assembly operation of the operator, improves the convenience of the operator's assembly, saves time and effort, and helps to improve production efficiency.

[0017] Optionally, the claw is located on the rear side of the mounting plate body, the claw is arc-shaped, and the inner side of the claw is arc-shaped with the side of the mounting plate body.

[0018] By adopting the above technical solution, the chuck is arc-shaped, and the inner side is arc-shaped with the side of the mounting plate body. That is, the chuck and the mounting plate body have a smooth transition, which is more friendly to the processing of the chuck and the mounting plate body, and is also conducive to the cooperation between the brake caliper and the chuck, and the brake caliper is stable when it is hung on the chuck.

[0019] Optionally, the mounting plate body is provided with a clearance opening.

[0020] By adopting the above technical solution, the opening of the clearance opening is beneficial for the installation of the mounting plate body and the axle housing, as well as for the installation of the brake caliper, thus avoiding interference with other vehicle components.

[0021] Optionally, the mounting wing plate and the mounting plate body are integrated into a single structure.

[0022] By adopting the above technical solution, the wing plate and the mounting plate body are integrated into a single structure, which helps to improve the structural stability of the overall components, improve production quality and efficiency, and ensure the machining accuracy of the overall components.

[0023] Optionally, a weight-reducing groove A is provided on one of the left and right sides of the mounting plate body, and a weight-reducing groove B is provided on the other left and right sides of the mounting plate body.

[0024] By adopting the above technical solutions, the setting of weight reduction groove A and weight reduction groove B ensures the lightweight requirement on the basis of part performance, which is conducive to improving structural strength, reducing material costs, and reducing weight, which is conducive to improving assembly convenience.

[0025] Optionally, the mounting plate body is arranged symmetrically on the top and bottom.

[0026] In summary, this application includes at least the following beneficial effects:

[0027] 1. The design of the mating surfaces and the opening of the mating holes in this application facilitates the installation of the brake caliper. The mating surfaces are perpendicular to the vehicle's driving direction, which helps improve the stability of the fit between the brake caliper and the mounting plate body. During braking, it is less likely to generate biased force. The mating holes are also opened along the vehicle's driving direction, which makes the bolts stable after bolt connection. The bolts are not easily subjected to shear force and are less likely to break. Moreover, the two mating surfaces are symmetrically arranged above and below the mounting plate holes, which helps improve installation stability, reduces the stress on the bolts connecting the mounting plate body and the brake caliper during emergency braking, reduces the requirements for the bolts, helps extend their service life, and is less likely to break. This ensures the installation stability of the brake caliper, reduces braking safety hazards, meets the requirements of high-speed and emergency braking conditions, and improves braking safety.

[0028] 2. The chucks in this application serve two purposes: firstly, during the machining of the mounting plate body, the chucks can be contacted for auxiliary positioning, facilitating positioning; secondly, during assembly, the brake calipers can be hung on the chucks, making assembly easier for operators, saving time and effort, and improving production efficiency.

[0029] 3. The integrated structure of the mounting wing plate and the mounting plate body in this application is conducive to improving the structural stability of the overall components, improving production quality and efficiency, and ensuring the machining accuracy of the overall components.

[0039] 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.

[0040] The following is in conjunction with the appendix Figures 1 to 7 This application will be described in further detail.

[0041] This application discloses a novel mounting plate for vehicle axles.

[0042] Reference Figures 1 to 3 A new type of mounting plate for vehicle axles, comprising:

[0043] Mounting plate body 1 is symmetrically arranged on the top and bottom. Mounting plate hole 2 is opened in the middle of mounting plate body 1. The opening of mounting plate hole 2 facilitates mounting plate body 1 onto axle housing 3, and facilitates the installation and fixation of mounting plate body 1 and axle housing 3. The connection can be made by welding.

[0044] Mounting wing plates 4 are provided at both the top and bottom of the mounting plate body 1. The two mounting wing plates 4 are symmetrically arranged along the mounting plate body 1, which helps to ensure the symmetry of the mounting plate body 1, making the mass of the upper and lower ends of the mounting plate body 1 uniform, which is more conducive to the installation of the mounting plate body 1 and the braking force is more favorable. The mounting wing plates 4 are integrated with the mounting plate body 1, which helps to improve the structural stability of the overall components, improve production quality and efficiency, and ensure the machining accuracy of the overall components.

[0045] On the front and rear sides of the mounting wing plate 4, mating surfaces 5 are provided perpendicular to the vehicle's travel direction, and these mating surfaces 5 are precision-machined. The precision machining of the mating surfaces 5 improves surface accuracy, enhances their flatness, ensures they are perpendicular to the vehicle's travel direction, improves precision, reduces the slippage force on the brake caliper during braking, and lowers the possibility of slippage between the brake caliper and the mating surfaces 5 during braking.

[0046] Two mating holes 6 are provided on the mating surface 5 along the vehicle's driving direction. These holes 6 extend through the mounting wing plate 4 from front to back, and are used to fix the brake caliper to the mounting wing plate 4 using bolts. Since the mating holes 6 extend from front to back and are in the same direction as the vehicle's driving direction, when braking, the brake caliper is subjected to force, pressing against the mounting plate. The mounting plate experiences a reaction force. Because the mating holes 6 extend from front to back, and the bolt connection direction is in the front-back direction, the bolt does not receive a biased component force and therefore does not bear the reaction force during braking. This reduces the stress on the bolt, lowers the requirements for the bolt, extends its service life, reduces the likelihood of breakage, ensures the installation stability of the brake caliper, guarantees vehicle braking stability, and reduces the possibility of brake failure.

[0047] The design of the mating surface 5 and the opening of the mating hole 6 facilitates the installation of the brake caliper. The mating surface 5 is perpendicular to the vehicle's driving direction, which helps improve the stability of the fit between the brake caliper and the mounting plate body 1. During braking, it is less likely to generate a biased force. The mating hole 6 is also opened along the vehicle's driving direction, which makes the bolts stable after bolt connection. The bolts are not easily subjected to shear force and are less likely to break. Moreover, the two mating surfaces 5 are symmetrically arranged vertically along the mounting plate hole 2, which helps improve installation stability and reduces the stress on the bolts connecting the mounting plate body 1 and the brake caliper during emergency braking. This solves the problem of bolt breakage under shear force between the mounting plate body 1 and the brake caliper, reduces the requirements for bolts, reduces the possibility of brake failure, reduces braking safety hazards, meets the requirements of high-speed and emergency braking conditions, and improves braking safety.

[0048] A chuck 7 is provided on the rear side of the mounting plate body 1. The chuck 7 is arc-shaped, and the inner side of the chuck 7 forms an arc with the side of the mounting plate body 1. The chuck 7 serves two purposes: firstly, it allows for auxiliary positioning during machining of the mounting plate body 1, facilitating easy positioning; secondly, during assembly, the brake caliper can be hung on the chuck 7, making assembly easier for operators, saving time and effort, and improving production efficiency. The arc shape of the chuck 7, with its arc-shaped inner side and the arc-shaped side of the mounting plate body 1, ensures a smooth transition between the chuck 7 and the mounting plate body 1, making machining of both easier and facilitating the cooperation between the brake caliper and the chuck 7, ensuring stability when the brake caliper is hung on the chuck 7.

[0049] The mounting plate body 1 has a weight reduction groove A8 on one of its left and right sides, and a weight reduction groove B9 on the other left and right sides. The weight reduction grooves A8 and B9 are designed to meet the lightweight requirements while ensuring the performance of the parts. This helps to improve structural strength, reduce material costs, and reduce weight, which in turn improves assembly convenience.

[0050] The mounting plate body 1 has an clearance opening 10. The clearance opening 10 facilitates the installation of the mounting plate body 1 and the axle housing 3, and also facilitates the installation of the brake caliper, avoiding interference with other vehicle components, such as the ABS sensor.

[0051] like Figures 4 to 7 As shown, the axle housing 3, wheel hub tube 11, and mounting plate are assembled. The axle housing 3 and wheel hub tube 11 are welded by friction welding. Then, the mounting plate is formed from a forged blank through blanking, heating, rough forging, precision forging, trimming, punching, and shaping, and then welded to the axle housing 3 assembly. After welding, it is clamped in a machining center in one step. First, the mating surface 5 is machined, then holes are drilled to machine the mating hole 6. The brake caliper is installed and fixed by bolts to the mating hole 6 to ensure a proper fit with the brake caliper.
