Description

Technical Field

[0001] This utility model belongs to the field of engineering vehicle technology, and in particular relates to an adjustable steering column. Background Technology

[0002] The steering column of a tractor can link the steering wheel rotation angle with the vehicle's steering gear through a drive shaft and universal joint, thus enabling the driver to control steering and other functions. Currently, most tractor hydraulic lines on the market use fixed steering columns with fixed angles that cannot be adjusted. This makes them unsuitable for drivers of different heights, builds, and driving habits, leading to ergonomic problems, premature driver fatigue, and impacting safety and work efficiency. While some adjustable steering columns exist, their structures are often very complex, and the adjustment process is time-consuming, laborious, and unreliable. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable steering column that allows for free adjustment of the steering wheel angle to meet the needs of different drivers.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] In a first aspect, this utility model provides an adjustable steering column, comprising:

[0006] Mounting base, steering column assembly, steering column sleeve, steering column mounting bracket and angle adjustment mechanism;

[0007] The steering column assembly and steering column sleeve are vertically mounted on the mounting base. The steering column assembly includes an upper steering column and a lower steering column, which are connected by a steering mechanism. The steering column sleeve includes an upper sleeve, a middle sleeve, and a lower sleeve, which are correspondingly arranged with the upper steering column, the steering mechanism, and the lower steering column. The steering column fixing bracket is sleeved on the outside of the middle sleeve and is connected to the steering column assembly and the steering column sleeve by a limiting bolt. The first end of the angle adjustment mechanism is connected to the mounting base, and the second end is connected to the steering column assembly by an adjustment handle.

[0008] The upper end of the upper steering column is connected to the steering wheel via a spline, and the lower end of the lower steering column passes through the mounting base and is connected to the steering gear via a spline.

[0009] The steering mechanism is a universal joint.

[0010] The steering column assembly and the steering column sleeve are connected by bearings.

[0011] The mounting base is provided with a parallel left fixing plate and a right fixing plate. An angle adjustment mechanism is installed between the left fixing plate and the right fixing plate. The first end of the angle adjustment mechanism is connected to the left fixing plate and the right fixing plate through a pin.

[0012] The steering column mounting bracket is a C-shaped bent plate, and the steering mechanism is connected to the bottom surface of the steering column mounting bracket via bearings.

[0013] The angle adjustment mechanism is a steplessly adjustable gas spring.

[0014] Secondly, this utility model provides an excavator, including the aforementioned adjustable steering column.

[0015] Beneficial effects: The adjustable steering column of this utility model can achieve stepless adjustment of the steering wheel angle, which is convenient for users of different body types to adjust the steering wheel height. The adjustment process is simple and efficient, thus making it easier for users to drive the vehicle and improving the ergonomics of the driving system. The steering column assembly is fixed and protected by the steering column fixing bracket to ensure the stability of the adjustment process. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Example 1

[0021] refer to Figure 1 and Figure 2 As shown, an adjustable steering column includes a mounting base 1, a steering column assembly 3, a steering column sleeve 2, a steering column fixing bracket 6, and an angle adjustment mechanism 7.

[0022] The steering column assembly 3 and the steering column sleeve 2 are vertically mounted on the mounting base. The steering column assembly 3 includes an upper steering column 31 and a lower steering column 33, which are connected by a steering mechanism 32. The steering column sleeve 2 includes an upper sleeve, a middle sleeve, and a lower sleeve, which are correspondingly arranged with the upper steering column 31, the steering mechanism 32, and the lower steering column 33. The steering column fixing bracket 6 is sleeved on the outside of the middle sleeve and is connected to the steering column assembly 3 and the steering column sleeve 2 by a limiting bolt 5. The first end of the angle adjustment mechanism 7 is connected to the mounting base 1, and the second end is connected to the steering column assembly 3 by an adjustment handle 4.

[0023] In this embodiment, the steering column assembly 3 includes an upper steering column 31, a steering mechanism 32, and a lower steering column 33 connected in sequence. The lower end of the lower steering column 33 passes through the mounting base 1 and is connected to the steering gear via a spline. The upper end of the upper steering column 31 is connected to the steering wheel via a spline.

[0024] The steering column mounting bracket 6 is a C-shaped bent plate, and the steering mechanism 32 is connected to the bottom surface of the steering column mounting bracket 6 through a bearing.
