Problems solved by technology

In the actual use of this type of steering mechanism, when it is applied to agricultural vehicles, such as tractors, due to the uneven surface of the farmland, there are often field ridges between the fields, and the driving environment of the vehicle is relatively harsh. Interference with obstacles in the farmland greatly affects the normal driving of agricultural vehicles in the farmland. Moreover, when a large number of obstacles gather at the transverse tie rod, it will hinder the left and right movement of the transverse tie rod, thus affecting the normal operation of the steering mechanism. running, which is not conducive to the normal turning of the vehicle

Embodiment Construction

[0024] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] A specific embodiment 1 of an agricultural vehicle of the present invention, such as Figure 1 to Figure 6 Shown, comprise vehicle frame 1, and vehicle frame 1 comprises crossbeam and vertical beam, and left and right steering wheel 2 is installed on the vertical beam, and the inboard of left and right steering wheel 2 is respectively equipped with left and right steering mechanism 3, left and right The steering mechanism 3 all independently drives the side steering wheel 2 to turn. The structures of the left and right steering mechanisms 3 are roughly the same, and are symmetrical to each other.

[0026] Wherein, the specific structure of the steering mechanism 3 includes a driving device and a transmission structure arranged between the driving device and the steering wheel 2. In this embodiment, the driving device is an oil cylinder 31 horizon...

Abstract

The invention relates to an agricultural vehicle. The agricultural vehicle comprises a vehicle frame and left and right steering wheels arranged on the vehicle frame, and left and right steering mechanisms for respectively driving the left and right steering wheels to steer are arranged on the vehicle frame, wherein the left and right steering mechanisms are arranged oppositely to each other. According to the agricultural vehicle, a set of steering mechanism individually driving the steering wheel to steer is arranged on each steering wheel. Compared with an existing steering mechanism driving all steering wheels to roll together through one driving device driving a connecting rod system used in the existing vehicle, there are no transverse connecting rods used for connection between the left and right steering wheels in the agricultural vehicle, so that the agricultural vehicle can pass by the top of an obstacle in the fields smoothly when traveling in the fields, and therefore, smooth traveling and turning of the agricultural vehicle in the fields are achieved.

Description

technical field [0001] The invention relates to an agricultural vehicle. Background technique [0002] At present, the steering mechanism on the vehicle generally adopts a link system steering mechanism, and a driving device drives the link system to drive all the steering wheels to rotate together. The link system generally includes a transverse tie rod and a longitudinal tie rod. In the actual use of this type of steering mechanism, when it is applied to agricultural vehicles, such as tractors, due to the uneven surface of the farmland, there are often field ridges between the fields, and the driving environment of the vehicle is relatively harsh. Interference with obstacles in the farmland greatly affects the normal driving of agricultural vehicles in the farmland. Moreover, when a large number of obstacles gather at the transverse tie rod, it will hinder the left and right movement of the transverse tie rod, thus affecting the normal operation of the steering mechanism. ...
