Description

Technical Field

[0001] This utility model relates to the field of tractor chassis technology, and in particular to a multifunctional tractor front drive axle fixed support. Background Technology

[0002] The front drive axle of a tractor is the core component for transmission and load bearing. It transmits power to the front wheels through the central drive assembly, drive half shafts, and other structures, while supporting the tractor's load and realizing the steering function.

[0003] However, traditional tractor front drive axles are often fixed in front of the engine, resulting in an excessively long distance between the front and rear wheels. This requires the tractor to allow more turning space when turning in narrow areas, severely limiting its steering flexibility. Secondly, this layout forces the front wheel size to be compressed to fit the structural space, which reduces the contact area and adhesion between the tires and the ground, and weakens the front load-bearing capacity. Under heavy loads or when climbing hills, it is very easy to cause the front wheels to lift off the ground, resulting in poor passability. In addition, the excessive extension of the front cantilever creates a long lever structure at the front. When equipped with a front counterweight, the fixed support of the front drive axle needs to withstand a greater bending moment load. Long-term use can easily lead to deformation and cracking of the support seat, which not only shortens the life of the components but also increases the risk of failure in field operations.

[0004] Prior art 1 (Chinese patent application number CN202323581149.7, application date 2023-12-27) discloses an electric motor driven tractor front axle, which solves the problem that the front wheel speed is difficult to maintain within the speed limit range, leading to easy wear of the front wheel. It eliminates the complex mechanical transmission route, which not only saves space but also improves transmission efficiency. The electric drive front axle can feed back the signal from the speed sensor to the vehicle controller to change the speed of the front axle to achieve the best transmission effect. While reducing the wear rate of the front wheel, it ensures the stable operation of the tractor front axle. When the tractor is transporting on the road, the power of the drive motor is cut off by the vehicle controller to achieve rear-wheel drive. No manual operation is required. The speed of the electric drive front axle can be changed at any time by the on-board computer. The optimal speed is calculated by combining the speed sensors of the rear wheels and the front wheels with the tire radii of the front and rear wheels.

[0005] Prior art 2 (Chinese patent application number CN202020794517.3, application date 2020-05-14) discloses a special front drive axle for greenhouse tractors, including a housing, a central transmission mechanism, left and right half shafts, left and right end drive shafts, etc., as well as left and right universal joints, planetary gear mechanism and end drive housing. There are two shafts on each side of the housing, and the left and right end drive housings are rotatably connected to the corresponding shafts. The left and right end drive shafts are in the corresponding drive housings. The left and right half shafts are connected to the left and right end drive shafts via universal joints, and then connected to the left and right planetary gear mechanism and end drive housing. This drive axle eliminates the left and right vertical shafts of the prior art. The left and right half shafts are directly connected to the end drive shafts by universal joints, with zero height difference, which can reduce the height of the machine body. It also overcomes the shortcomings of the prior art, which is limited by the vertical shaft seat structure and has a small steering angle. The rotation angle of the left and right end drive housings reaches 51°, which meets the requirements of greenhouse field operation. Utility Model Content

[0006] The purpose of this utility model is to provide a multifunctional tractor front drive axle fixing support to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: it includes a support frame body, a lubricating oil storage shell is provided at the front of the support frame body, a front drive axle fixing seat one is provided at the bottom of the support frame body at the rear of the lubricating oil storage shell, a front drive axle fixing seat two is provided on the side of the bottom of the support frame body away from the front drive axle fixing seat one, and a flywheel housing fixing seat is provided at the rear of the support frame body.

[0008] In a preferred embodiment of this invention, the support frame body is connected to the front drive axle via a front drive axle fixing seat one and a front drive axle fixing seat two.

[0009] As a preferred embodiment of this invention, the flywheel housing mounting bracket is used to connect the engine flywheel housing.

[0010] As a preferred embodiment of this utility model, mounting seats are provided on both sides of the lubricating oil storage shell, and the lubricating oil storage shell is connected to the battery water tank support frame through the mounting seats.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] This utility model comprises a support frame body, a lubricating oil reservoir, a mounting base, a front drive axle mounting base one, a front drive axle mounting base two, a flywheel housing mounting base, and a battery water tank support frame. The support frame body serves as the mounting foundation for the entire structure. Through integrated design, it achieves spatial integration of core components such as the engine block, front drive axle, and lubricating oil reservoir, ensuring structural strength while optimizing the compact layout. Furthermore, the lubricating oil reservoir at the front of the support frame body stores lubricating oil, saving space while ensuring continuous lubrication of the engine, effectively extending mechanical life and reducing maintenance frequency. The mounting base on the side of the storage shell serves as the mounting base, supporting the battery water tank support frame located at its front. This provides a stable mounting point for the tractor's water tank, battery, and other components, enabling integrated fixation of these parts. In addition, the dual-point fixing structure of the front drive axle mounting base one and the front drive axle mounting base two significantly reduces the distance between the front and rear wheels by moving the mounting position of the front drive axle backward, thereby reducing the turning radius and improving the tractor's flexibility in narrow spaces. Finally, the flywheel housing mounting base provides rigid support for the engine flywheel housing, effectively suppressing vibration and displacement during power transmission and ensuring the stability and reliability of power transmission.
