Technical Field

[0001] This utility model relates to the technical field of rear support brake axle assembly, and in particular to a rear support brake axle assembly for a 35T heavy-duty vehicle. Background Technology

[0002] The support brake axle assembly is a key component in the rear axle system of heavy-duty vehicles. It combines the load-bearing function of the support axle with the deceleration function of the brake axle, and achieves efficient power transmission, stable load-bearing and reliable braking through optimized structural design.

[0003] As disclosed in announcement number CN2537593Y, a heavy-duty vehicle rear axle housing assembly includes a rear axle housing and a half-shaft sleeve. The rear axle housing is a cast axle housing. The key feature is that the half-shaft sleeve is inserted into the rear axle housing with an interference fit, and is secured at the fit by a fastening pin. This structure solves the problem of stress concentration caused by the original weld seams. By using an interference fit and fastening pins, the structure becomes more rational, eliminating stress concentration.

[0004] This patent can solve the problem of stress concentration caused by welds. However, existing structures do not have a protective structure on their surface when in use. They are exposed to complex working conditions such as mud, gravel, rainwater, and salt spray corrosion for a long time, which seriously affects their service life. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing structures, when in use, lack a protective surface and are exposed to complex working conditions such as mud, gravel, rainwater, and salt spray corrosion for a long time, which seriously affects their service life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a 35T heavy-duty vehicle rear support brake axle assembly, comprising an assembly body, protective components connected to both sides of the assembly body, the protective components including an upper protective cover, a guide groove opened on the inner side of the assembly body, a lower protective cover connected to both bottom surfaces of the assembly body, upper side ears connected to the four corners of the upper protective cover, a sleeve connected to the surface of each set of upper side ears, a spring provided inside each set of sleeves, a hand-tightening bolt inserted inside each set of springs, and a limit block fixedly connected to the surface of the hand-tightening bolt.

[0007] Furthermore, each of the four corners of the lower protective cover is connected to a lower side lug, and each set of lower side lugs has a threaded hole on its surface.

[0008] Furthermore, the limiting block and the spring form an elastic structure, and the hand-tightening bolt, after passing through the sleeve, forms a threaded connection with the threaded hole of the lower ear.

[0009] Furthermore, the inner walls of the upper and lower protective covers are fitted to the outer surfaces of both sides of the main body of the assembly.

[0010] Furthermore, a temperature monitoring component is provided on the inner wall of the lower protective cover, the temperature monitoring component includes a temperature sensor, and an alarm is connected to the center of the front end of the main body of the assembly.

[0011] Furthermore, the alarm is electrically connected to the temperature sensor, which is electrically connected to an external power source via a control switch.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when in use, the upper and lower protective covers can protect the two sides of the main body of the assembly, avoiding the problem of the main body of the assembly being exposed to complex working conditions such as mud, gravel, rainwater, and salt spray corrosion for a long time, which would reduce the service life of the main body of the assembly.

[0013] 2. In this utility model, when the main body of the assembly is in a high-temperature state, the temperature sensor can achieve real-time temperature monitoring. When the temperature reaches the alarm temperature, the alarm will automatically turn on to remind the driver to take timely action and ensure driving safety. Attached Figure Description

Detailed Implementation

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1, such as Figure 1 - Figure 3 As shown, this utility model provides a 35T heavy-duty vehicle rear support brake axle assembly, including an assembly body 1. Protective components 2 are connected to both sides of the assembly body 1. Each protective component 2 includes an upper protective cover 201. A guide groove 202 is formed on the inner side of the assembly body 1. Lower protective covers 209 are connected to both bottom surfaces of the assembly body 1. Upper side ears 204 are connected to the four corners of the upper protective cover 201. A sleeve 205 is connected to the surface of each set of upper side ears 204. Each set of sleeves 205... Each sleeve 205 has a spring 206 inside, and each set of springs 206 has a hand-tightening bolt 207 inserted inside. The surface of the hand-tightening bolt 207 is fixedly connected to a limit block 208. The four corners of the lower protective cover 209 are connected to lower side ears 210. The surface of each set of lower side ears 210 is provided with a threaded hole 211. The limit block 208 and the spring 206 form an elastic structure. The hand-tightening bolt 207 passes through the sleeve 205 and forms a threaded connection with the threaded hole 211 of the lower side ear 210.

[0019] The effect achieved by embodiment 1 is that when installing the protective component 2, both the upper protective cover 201 and the lower protective cover 209 can be pushed into the guide groove 202 through the guide block 203. After the upper protective cover 201 and the lower protective cover 209 are in contact, the hand-tightening bolt 207 is rotated forward so that the front end of the hand-tightening bolt 207 can pass through the sleeve 205 and the upper side ear 204 and be threaded and fixed to the threaded hole 211 of the lower side ear 210. After fixing, the spring 206 will always push the limit block 208 through its own elastic force, reducing the possibility of the hand-tightening bolt 207 loosening. When disassembling, the hand-tightening bolt 207 can be reversed so that the front end of the hand-tightening bolt 207 can be taken out from the threaded hole 211 of the lower side ear 210. Then, the upper protective cover 201 and the lower protective cover 209 can be completely removed to complete the disassembly. This avoids the problem of the assembly body 1 being exposed to complex working conditions such as mud, gravel, rainwater, and salt spray corrosion for a long time, which leads to a reduction in the service life of the assembly body 1.

[0020] Example 2, as Figure 1 As shown, a temperature monitoring component 3 is provided on the inner wall of the lower protective cover 209. The temperature monitoring component 3 includes a temperature sensor 301. An alarm 302 is connected to the center of the front end of the main body 1. The alarm 302 and the temperature sensor 301 are electrically connected. The temperature sensor 301 is electrically connected to an external power supply through a control switch.

[0021] The effect achieved by embodiment 2 is that when the main body 1 of the supporting brake axle assembly is under heavy load, continuous braking or complex road conditions such as long downhill, the heat generated by gear meshing, bearing friction and brake disc friction in the axle body will continue to accumulate. The temperature sensor 301 can achieve the purpose of real-time temperature monitoring. When the temperature reaches the alarm temperature, the alarm 302 will automatically turn on to remind the driver to deal with it in time, thus ensuring driving safety.

[0022] Working principle: When in use, the upper protective cover 201 and the lower protective cover 209 can protect the two sides of the main body of the assembly 1, avoiding the problem of the main body of the assembly 1 being exposed to complex working conditions such as mud, gravel, rainwater, and salt spray corrosion for a long time, which would reduce the service life of the main body of the assembly 1. When the main body of the assembly 1 is in a high temperature situation, the temperature sensor 301 can achieve the purpose of real-time temperature monitoring. When the temperature reaches the alarm temperature, the alarm 302 will automatically activate to remind the driver to deal with it in time, ensuring driving safety.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
