Description
Technical Field
[0001] This utility model relates to the field of vehicle axle application technology, specifically an improved vehicle axle. Background Technology
[0002] Currently, as a key component of the automobile chassis, the axle's main function is to transmit various forces and torques between the frame and the wheels, playing a decisive role in the vehicle's driving performance, load-bearing capacity, and safety. Traditional axles generally consist of axle housing, main reducer, differential, and half-shafts. The axle's structural design is relatively fixed, and the axle housing is mostly manufactured using casting or forging processes, resulting in a large overall mass, increasing the vehicle's weight, leading to increased fuel consumption, reduced fuel economy, and hindering the achievement of lightweight design goals. This also limits the improvement of the driving range of new energy vehicles. The installation space and connection methods of traditional axles are relatively simple, making it difficult to adapt to the diverse design needs of different vehicle models, and posing significant limitations in the process of vehicle modification and upgrades. Utility Model Content
[0003] The purpose of this invention is to provide an improved axle to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an improved axle, comprising a short half-shaft assembly, a differential, and a long half-shaft assembly. The short half-shaft assembly is mounted on one end of the differential, and a first flange is mounted on one end of the short half-shaft assembly. The main function of the differential is to allow the left and right wheels to rotate at different speeds when the vehicle is turning, while simultaneously transmitting engine power to the wheels. The short half-shaft assembly, mounted on one end of the differential, effectively transmits the power output from the differential to the wheels. After the engine output power is transmitted to the differential via components such as the transmission, the short half-shaft assembly, as an intermediate link in power transmission, ensures that power can be continuously and stably transmitted to subsequent components, enabling the vehicle to drive normally. A first wheel hub sensor is mounted on the inner side of the first flange. The first wheel hub sensor can monitor parameters such as wheel speed and temperature in real time and transmit this data to the vehicle's control system in a timely manner, providing support for the vehicle's driving stability and safety. A crucial safeguard is provided by a long half-shaft assembly mounted on the other end of the differential. A second flange is installed on one end of the long half-shaft assembly, and a second wheel hub sensor is mounted on the inner wall of the second flange. The long half-shaft assembly and the short half-shaft assembly complement each other, jointly undertaking the crucial task of transmitting the power output from the differential to the wheels. The long half-shaft assembly ensures efficient and stable power transmission under various complex operating conditions that the vehicle may encounter during driving. The second flange, as the connecting component between the long half-shaft assembly and the wheel, not only provides fixation and support but also, through the second wheel hub sensor mounted on its inner wall, enables real-time monitoring of parameters such as the speed and temperature on the other side of the wheel. Wheel hub studs are installed on the outer walls of the first and second flanges. As a key connecting component, the wheel hub studs not only enhance the connection strength between the first and second flanges and the wheel but also ensure the stability and safety of the wheel under high-speed driving or complex road conditions.
[0005] Preferably, the short half-shaft assembly is provided with a short half-shaft sleeve. One end of the short half-shaft sleeve is sealed to the first flange through a short sealing shaft seat. The short half-shaft sleeve enhances the structural strength of the short half-shaft assembly and, through the sealing connection between the short sealing shaft seat and the first flange, effectively prevents impurities such as oil or water from entering the axle, ensuring the normal operation of the axle and extending its service life.
[0006] Preferably, a first sealing mounting plate is installed at the other end of the short half-shaft sleeve. The first sealing mounting plate is sealed to one side of the differential through a first mating sleeve. A short adjusting mounting seat is welded on the outer wall of the short half-shaft sleeve. The setting of the short adjusting mounting seat not only facilitates the installation and adjustment of the short half-shaft assembly, but also enhances the overall rigidity and stability of the short half-shaft sleeve. The first sealing mounting plate and the differential are sealed together through the first mating sleeve, which effectively prevents external pollutants such as dust and moisture from entering the interior of the differential, thus protecting the normal operation of the differential.
[0007] Preferably, the long half-shaft assembly is provided with a long half-shaft sleeve, one end of which is sealed to the second flange through a long sealing shaft seat. The long half-shaft sleeve not only enhances the structural strength of the long half-shaft assembly, but also effectively prevents impurities such as oil or water from penetrating into the critical parts of the axle through the sealing connection between the long sealing shaft seat and the second flange, ensuring the smooth operation of the axle and further improving its service life.
[0008] Preferably, a second sealing mounting plate is installed at the other end of the long half-shaft sleeve. The second sealing mounting plate is sealed to the other side of the differential through a second mating sleeve. A long adjusting mounting seat is welded on the outer wall of the long half-shaft sleeve. The setting of the long adjusting mounting seat not only provides a more stable mounting base for the long half-shaft assembly, but also facilitates precise adjustment to adapt to different installation environments and needs. The sealed connection between the second sealing mounting plate and the differential through the second mating sleeve enhances the sealing performance of the differential and effectively blocks external contaminants.
[0009] Preferably, the first flange and the first hub sensor, as well as the second flange and the second hub sensor, are all embedded mounting structures. The embedded mounting structure makes the connection between the flange and the hub sensor tighter, which not only improves the stability of the installation, but also effectively reduces the problem of unstable signal transmission caused by looseness or excessive gap.
[0010] Compared with the prior art, the beneficial effects of this utility model are: The long half-shaft assembly and the short half-shaft assembly of this utility model complement each other in function, jointly undertaking the important task of transmitting the power output from the differential to the wheels. The long half-shaft assembly ensures the efficiency and stability of power transmission in various complex working conditions that the vehicle may encounter during driving. The second flange, as the connecting component between the long half-shaft assembly and the wheel, not only plays a role in fixing and supporting, but also realizes real-time monitoring of parameters such as speed and temperature on the other side of the wheel through the second wheel hub sensor installed on its inner side wall. The first flange and the outer side wall of the second flange are equipped with wheel hub studs. As a key connecting component, the wheel hub studs not only enhance the connection strength between the first flange and the second flange and the wheel, but also ensure the stability and safety of the wheel under high-speed driving or complex road conditions.
