Description

Technical Field

[0001] This utility model relates to the field of automotive rear axle technology, specifically to a reinforced rear axle device suitable for harsh working conditions. Background Technology

[0002] The rear axle refers to the rear drive shaft component that transmits power to a vehicle. It consists of two half-axles, allowing for differential movement between the half-axles. It also supports the wheels and connects them. In front-wheel-drive vehicles, the rear axle is merely a follow-up axle, serving only a load-bearing function. If the front axle is not a drive axle, then the rear axle is the drive axle, in which case it provides load-bearing, driving, deceleration, and differential functions. In four-wheel-drive vehicles, a transfer case is usually located in front of the rear axle. Rear axles are divided into solid axles and half-axles. Solid axles are paired with non-independent suspensions, such as leaf spring suspensions, while half-axles are paired with independent suspensions, such as MacPherson strut suspensions.

[0003] However, in the existing technology, when the road section where the car is driving is relatively bumpy and muddy, the working environment of the rear axle of the car is relatively harsh. Since the rear axle is exposed under the car floor, it will be contaminated with sewage, mud and stones from collisions. This can easily block the air vents on the rear axle that balance the air pressure with the outside, causing the pressure inside the rear axle housing to increase, resulting in leakage of the sealing components and affecting the transmission. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforced rear axle device suitable for harsh working conditions, which has the advantage of protecting the vent 104 and preventing mud and sand from entering and causing blockage when the vehicle is driving on muddy roads, thus preventing the pressure inside the axle housing 101 from increasing and causing leakage of the sealing parts and affecting the transmission, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforced rear axle device suitable for harsh working conditions, comprising a rear axle assembly, a cleaning assembly, and an exhaust assembly. The rear axle assembly is used for transmission and travel when mounted under a vehicle platform. The cleaning assembly is disposed on the rear axle assembly for cleaning and unblocking in harsh environments. The exhaust assembly is disposed within the cleaning assembly for balancing the air pressure inside the rear axle assembly with the external air pressure. The rear axle assembly includes an axle housing, a reducer, a connecting flange, two vent holes, two leaf spring seats, two transmission seats, two brake hubs, and two wheel hubs.

[0006] Furthermore, the corresponding vent hole knob has a sealing bolt, and a support plate is fixedly installed on both leaf spring seats, and the support plate is fixedly connected to the bridge housing.

[0007] Furthermore, the cleaning assembly includes a fixed assembly and a movable assembly. The fixed assembly is disposed within the vent hole, and the movable assembly is disposed on the fixed assembly. The fixed assembly includes a connecting pipe, a mounting plate, a connecting block, a fixing block, a mounting base, a first vent cover, and an annular scraper. The connecting pipe knob is located within the vent hole. The mounting plate is fixedly mounted on the top end of the connecting pipe.

The mounting base is fixedly mounted on the outer wall of the fixing block. The first vent cover is fixedly mounted on the top of the mounting base, and the annular scraper is fixedly mounted on the top of the first vent cover.

[0008] Furthermore, the movable component includes a protective cover, a second ventilated cover, and a spring. The protective cover is disposed above the fixed block, the second ventilated cover is fixedly installed on the top inner wall of the protective cover, the spring is fixedly installed on the top inner wall of the protective cover, and the bottom end of the spring is fixedly connected to the top of the fixed block.

[0009] Furthermore, the cross-section of the annular scraper is rhomboid, and the scraping area of ​​the annular scraper is set at an acute angle.

[0010] Furthermore, an inner cover is fixedly installed inside the protective cover, and the inner wall of the inner cover is arc-shaped.

[0013] This invention, by setting a rear axle assembly, connects the car's drive rod to the connecting flange via fasteners. When the car is in motion, the car engine drives the drive rod to rotate, which in turn drives the connecting flange to rotate. The rotating connecting flange activates the reducer, which in turn drives the connecting rod inside the axle housing to rotate. The connecting rod, through the transmission seat, drives the brake drum to rotate, which in turn drives the wheel hub to rotate. The wheel hub then drives the wheels to rotate, propelling the car forward. This design offers the advantages of continuous transmission and the ability to drive the car even in harsh working environments. Attached Figure Description

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] This utility model provides, for example Figures 1-6As shown, a reinforced rear axle device suitable for harsh working conditions includes a rear axle assembly 1, a cleaning assembly 2, and an exhaust assembly 3. The rear axle assembly 1 is installed under the vehicle platform for transmission and travel. The cleaning assembly 2 is installed on the rear axle assembly 1 for cleaning and unblocking in harsh environments. The exhaust assembly 3 is installed inside the cleaning assembly 2 to connect and balance the air pressure inside the rear axle assembly 1 with the external air pressure. The rear axle assembly 1 includes an axle housing 101, a reducer 102, a connecting flange 103, two vent holes 104, two leaf spring seats 105, two transmission seats 106, two brake drums 107, and two wheel drums 108. The reducer 102 is fixedly installed on the axle housing 101 by fasteners. The connecting flange 103 is fixedly installed on the reducer 102. Both vent holes 104 are formed on the axle housing 101, and both leaf spring seats 105 are fixedly installed on the axle housing 101. Mounted on the axle housing 101, both transmission seats 106 are fixedly mounted on the axle housing 101, and both brake hubs 107 are fixedly mounted on the two transmission seats 106 by fasteners. Both wheel hubs 108 are fixedly mounted on the two brake hubs 107 by fasteners. More specifically, the vehicle's transmission rod is connected to the connecting flange 103 by fasteners. When the vehicle is in motion, the vehicle engine drives the transmission rod to rotate, which in turn drives the connecting flange 103 to rotate. The rotating connecting flange 103 activates the reducer 102, which in turn drives the connecting rod inside the axle housing 101 to rotate. The connecting rod, through the transmission seats 106, drives the brake hubs 107 to rotate, which in turn drives the wheel hubs 108 to rotate. The wheel hubs 108 then drive the wheels to rotate, propelling the vehicle forward. This design provides the advantage of continuous transmission and allows for transmission and driving even in harsh working environments.

[0019] In addition, the corresponding vent hole 104 has a sealing bolt inside the knob, and a support plate is fixedly installed on both leaf spring seats 105. The support plate is fixedly connected to the bridge housing 101.

[0020] like Figure 1As shown, the cleaning component 2 includes a fixed component and a movable component. The fixed component is disposed within the vent hole 104, and the movable component is disposed on the fixed component. The fixed component includes a connecting pipe 201, a mounting plate 202, a connecting block 203, a fixing block 204, a mounting base 205, a vent hood 206, and an annular scraper 207. The connecting pipe 201 is knobbed within the vent hole 104. The mounting plate 202 is fixedly mounted on the top of the connecting pipe 201. The connecting block 203 is fixedly mounted on the top of the mounting plate 202. The fixing block 204 is fixedly mounted on the top of the connecting block 203. The mounting base 205 is fixedly mounted on the outer wall of the fixing block 204. The vent hood 206 is fixedly mounted on the top of the mounting base 205. The annular scraper 207 is fixedly mounted on the top of the vent hood 206. More specifically, this allows the bridge housing 101 to operate in harsh environments when driving on muddy roads. When driving on bumpy roads, mud, sand, and gravel will come into contact with and impact the protective cover 208, causing it to move under pressure. This movement compresses the spring 210, causing it to deform and accumulate elastic force. The protective cover 208 then moves the second vent 209, which moves downwards and comes into contact with the annular scraper 207. The scraper 207 cleans the second vent 209 by scraping it. Through the cooperation of the protective cover 208 and the scraper 207, the protective cover 208 protects the vent 104, preventing mud and sand from entering and causing blockages under harsh working conditions. The scraper 207 keeps the second vent 209 clean, preventing blockages that could affect ventilation. This system has the advantage of protecting the vent 104, preventing mud and sand from entering and causing blockages when the vehicle is driving on muddy roads, thus preventing increased pressure inside the axle housing 101 and potential leakage of the seals that could affect transmission.

[0021] In addition, the movable component includes a protective cover 208, a second ventilation cover 209, and a spring 210. The protective cover 208 is disposed above the fixed block 204. The second ventilation cover 209 is fixedly installed on the top inner wall of the protective cover 208. The spring 210 is fixedly installed on the top inner wall of the protective cover 208, and the bottom end of the spring 210 is fixedly connected to the top of the fixed block 204.

[0022] In addition, the cross-section of the annular scraper 207 is rhomboid, and the scraping area of ​​the annular scraper 207 is set in an acute angle.

[0023] In some embodiments, an inner cover is fixedly installed inside the protective cover 208, and the inner wall of the inner cover is arc-shaped.

[0024] like Figure 1As shown, in some embodiments, the exhaust assembly 3 includes two rings 301, four connecting plates 302, a central plate 303, and four valves 304. The two rings 301 are fixedly installed on the inner wall of the fixing block 204. The four connecting plates 302 are respectively fixedly installed between the two rings 301. The central plate 303 is fixedly installed on the four connecting plates 302. The four valves 304 are respectively fixedly installed between the two rings 301. The valves 304 are made of rubber.

[0025] Working principle: Step 1: Connect the transmission. Connect the transmission rod of the car to the connecting flange 103 using fasteners. When the car is in motion, the car engine drives the transmission rod to rotate, which in turn drives the connecting flange 103 to rotate. The rotation of the connecting flange 103 starts the reducer 102. The reducer 102 drives the connecting rod inside the axle housing 101 to rotate. The connecting rod drives the brake drum 107 to rotate through the transmission seat 106. The brake drum 107 drives the wheel hub 108 to rotate, which in turn drives the wheel to rotate and propels the car.

[0026] Step Two: Cleaning and Protection. When driving on muddy roads, the bridge housing 101 operates in harsh conditions. During bumpy driving, mud, sand, and gravel will come into contact with and impact the protective cover 208, causing it to move under pressure. As the protective cover 208 moves, it compresses the spring 210, causing the spring 210 to deform and accumulate elastic force. The protective cover 208 drives the second ventilator 209 to move. The second ventilator 209 moves downward and comes into contact with the annular scraper 207. The annular scraper 207 scrapes and cleans the second ventilator 209. Through the cooperation of the protective cover 208 and the annular scraper 207, the protective cover 208 protects the vent 104, preventing mud and sand from entering and causing blockage under harsh working conditions. The annular scraper 207 scrapes the second ventilator 209 to keep it clean and prevent blockage from affecting ventilation.
