Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a steering component of a tractor, and specifically refers to a novel suspended front axle steering drive mechanism. Background Art

[0002] During the research of high-horsepower tractors, in order to meet the use requirements of high-horsepower tractors, our company first applied for a utility model patent with the publication number CN220298223U, named a new type of suspended front axle steering drive mechanism. This patented technology is related to the suspended drive of the front axle of high-horsepower tractors. The technology previously used front-wheel drive driven by a hydraulic cylinder, but although it can meet the use requirements, during the test process, this technology uses a single-cylinder double-piston rod structure hydraulic cylinder. When encountering complex ground and a large difference in ground height between the left and right wheels, due to the limitations of a single cylinder, it cannot meet the use requirements. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a novel suspended front axle steering drive mechanism in view of the deficiencies in the prior art. The steering drive mechanism utilizes a steering oil cylinder with two cylinders and two piston rods to perform steering power on the front wheels, and a swinging connecting component is provided. Each hydraulic cylinder is independently connected to the frame body. While satisfying the steering requirement when the heights of the left and right bridges are inconsistent, the range of different heights of the left and right bridges is wider and can better meet different road conditions.

[0004] The technical solution of the utility model is to provide the following novel suspended front axle steering drive mechanism, including a steering cylinder installed on a frame, two steering cylinders are symmetrically arranged, the cylinder body of the steering cylinder is connected to the frame through a ball bearing, the piston rod of the steering cylinder is connected to the steering housing through a ball bearing, and a mounting portion for mounting the steering cylinder is provided on the frame, and the mounting portion is a U-shaped connecting frame arranged on the frame.

[0005] As a further optimization, the frame includes a bottom plate and side plates, the side plates are provided with through holes that allow the steering cylinder to pass through, and the bottom plate is provided with process holes that facilitate the installation of the steering cylinder.

[0006] As a further optimization, the ball head bearing is installed on a U-shaped connecting frame and fixed by a pin or a bolt.

[0007] As a further optimization, a driving rod connected to a ball bearing is provided on the top of the piston rod, the position of the driving rod on the piston rod is adjustable, and a locking nut is provided on the driving rod.

[0008] The beneficial effects of adopting this technical solution are: two independent steering cylinders are used instead, and both ends of the steering cylinders are connected by ball bearings, which can achieve multi-angle swing, and the two independent steering cylinders no longer interfere with each other, and can adapt to roads with greater height differences.

[0013] For ease of explanation, the new suspended front axle steering drive mechanism of the utility model is described in detail below in conjunction with the accompanying drawings.

[0014] like Figures 1 to 3 As shown in the figure, a novel suspended front axle steering drive mechanism includes a steering cylinder 2 installed on a frame 1, and the steering cylinders 2 are two symmetrically arranged. The two symmetrically arranged steering cylinders 2 realize synchronous steering of two wheels by controlling the flow rate and direction of oil inlet and outlet. The utility model mainly involves the mechanical part, and the control system belongs to a separate system. The technology is relatively mature and will not be repeated here; the cylinder body of the steering cylinder 2 is connected to the frame 1 through a ball bearing, and the piston rod of the steering cylinder 2 is connected to the steering housing 3 through a ball bearing; a connecting part 9 is provided on the steering housing 3, and the connecting part 9 is connected to the piston rod of the steering cylinder, and the ball bearing realizes multi-angle adjustment such as up, down, left and right, to ensure that the steering effect is not affected during the lifting process.

[0015] The frame 1 is provided with a mounting portion 4 for mounting the steering cylinder 2; the frame 1 includes a bottom plate 11 and a side plate 12, the side plate 12 is provided with a through hole 5 for the steering cylinder 2 to pass through, the bottom plate 11 is provided with a process hole 6 for convenient installation of the steering cylinder 2, and the process hole is provided to facilitate the installation, inspection and maintenance of the steering cylinder; the mounting portion 4 is a U-shaped connecting frame provided on the frame 1, the ball bearing is installed on the U-shaped connecting frame and fixed by a connecting pin 10 or a bolt, Figure 3The center link pin 10 is represented by a simplified line; a driving rod 7 connected to a ball bearing is provided on the top of the piston rod, and the driving rod 7 can adjust the steering accuracy after assembly to achieve fine-tuning of the steering accuracy; the position of the driving rod 7 on the piston rod is adjustable, and a locking nut 8 is provided on the driving rod 7. The locking nut 8 can lock the driving cylinder after the adjustment is completed to prevent poor steering accuracy caused by changes in the position of the driving rod 7 during operation.

[0016] Two independent steering cylinders are used instead, and both ends of the steering cylinders are connected with ball bearings, which can achieve multi-angle swing. The two independent steering cylinders no longer interfere with each other and can adapt to roads with greater height differences.
