Description
Technical Field
[0001] The utility model relates to the technical field of vehicles, in particular to a wheel steering structure of a four-wheel drive all-terrain low-speed vehicle. Background Art
[0002] In actual situations, whether it is grazing on the grassland, sightseeing on the beach or farm scenic area, hunting in the snow, or even clearing snow in the northern community, people often need to use a simple means of transportation such as an all-terrain vehicle, because the all-terrain vehicle itself is relatively simple to operate, flexible and light, and can play a greater role and effect. However, in the actual operation of existing all-terrain vehicles, when encountering a situation where a turn is required, the front two wheels of the all-terrain vehicle are basically controlled to achieve steering, and the rear two wheels are relatively fixed, that is, they do not have the ability to actively turn. This results in the all-terrain vehicle itself having a large turning radius in the actual turning process. At the same time, the space required is also very large, and it is impossible to achieve turning and U-turns in a relatively narrow space. In this way, in the actual U-turn process, the operation is relatively cumbersome and at the same time, it is not flexible.
[0003] Therefore, in response to the current problems, how to provide a wheel steering structure for a four-wheel drive all-terrain low-speed vehicle to ensure that the all-terrain vehicle can achieve simultaneous steering of the front and rear four wheels during the steering process under the premise of simple mechanical improvements, thereby reducing the turning radius of the all-terrain vehicle, reducing the space required for turning and turning, ensuring that the all-terrain vehicle can be more flexible and easy to operate, and also saving costs and improving production efficiency is a problem that technical personnel in this field urgently need to solve.

The front wheel and the rear wheel are respectively sleeved on the front wheel mounting sleeve 2 and the rear wheel mounting sleeve 3. The front wheel mounting sleeve 2 has a first connection point on its outer side wall, and the first connection point is located on the front side of the central axis of the front wheel mounting sleeve 2. The rear wheel mounting sleeve 3 has a second connection point on its outer side wall, and the second connection point is located on the rear side of the central axis of the rear wheel mounting sleeve 3.
[0034] The wheel tie rods include a front wheel tie rod 5 and a rear wheel tie rod 6, and there are two of each. The first end of each front wheel tie rod 5 is fixed to a first connection point; the first end of each rear wheel tie rod 6 is fixed to a second connection point;
[0035] One end of the linkage part 7 is rotatably connected to the vehicle frame 1 , and the second ends of the front wheel tie rod 5 and the rear wheel tie rod 6 are both hinged to the other end of the linkage part 7 .
[0036] In some specific embodiments, the linkage part 7 includes a linkage rod 71 and a connecting plate 72. The length direction of the linkage rod 71 is arranged parallel to the front-rear direction of the frame 1, and its rod body is rotatably connected to the frame 1; there are two connecting plates 72, which are respectively fixed at both ends of the linkage rod 71, and the second ends of the front wheel tie rod 5 and the rear wheel tie rod 6 are correspondingly hinged on each connecting plate 72.
