Industrial vehicle capable of traveling in four directions and traveling mechanism of industrial vehicle

Abstract

The invention relates to an industrial vehicle transporter, in particular to an industrial vehicle capable of traveling in four directions and a traveling mechanism of the industrial vehicle. According to the technical scheme, the traveling mechanism of the industrial vehicle capable of traveling in the four directions comprises four wheel sets arranged at the bottom of a vehicle body, and the four wheel sets can form a quadrangle through sequential connection. One wheel set is a steering wheel set. Another wheel set is a reversing directional wheel set, and the axial direction of wheels of the wheel set can be switched between two directions through the rotating movements of the wheel sets. The other two wheel sets are state changeable wheel sets, and the states of wheels of the two wheel sets can be switched between the directional state and the follow-up universal directions. The traveling mechanism of the industrial vehicle is simple in structure, low in cost and beneficial for improving the application range of the industrial vehicle and improving use efficiency and maneuverability, and has good supporting stability.

Description

technical field [0001] The invention relates to an industrial vehicle transport vehicle, in particular to an industrial vehicle capable of traveling in four directions and a running mechanism of the industrial vehicle. Background technique [0002] In the prior art, there are ordinary trucks whose straight forward direction is consistent with the length direction of the forks and side trucks whose straight forward direction is perpendicular to the length direction of the forks. [0003] Ordinary truck walking mechanism such as figure 1 Shown, comprise cargo fork-5, left front wheel-51, right front wheel-52, left rear wheel-53, right rear wheel-54, wherein left rear wheel-53 is driving wheel, and driving wheel is controlled by operator to advance , Back or turn, the two front wheels are used as guide wheels, generally directional wheels, and the right rear wheel-54 is generally a follow-up universal wheel. This kind of truck can move forward, backward or turn freely; but tur...

Problems solved by technology

[0006] A utility model patent with the authorized notification number CN2288896Y discloses a four-wheel synchronous steering mechanism for electric counterbalanced forklifts. It includes an electric motor for driving a hydraulic oil pump, and a hydraulic steering gear connected to the hydraulic oil pump through pipelines. , and the sprocket oil cylinder controlled by the hydraulic steering gear, and the steering chain driven by the sprocket oil cylinder. The steering chain drives the wheel rotation shaft through the sprockets respectively installed on the wheel rotation shaft to realize the synchronization of the four wheels Steering; this kind of walking mechanism can theoretically make the truck move straight forward in all directions without turning the body, thereby improving the adaptability of the truck to the environment; however, this setting of synchronous steering of four wheels only requires It can drive in a straight line, and the vehicle cannot turn; when it is directly manufactured, the structure is complex and costly, and when it is obtained through the transformation of the aforementioned ordinary truck or side truck, the scope of modification is large, the structure is complex, the cost is high, and the transformation is also difficult

[0007] The invention patent application with the publication number CN1789105A discloses a kind of universal driving forklift, which includes a vehicle frame, which is connected with the front axle, and the front axle is connected with the mast. The left and right synchronous gear sets are fixed on the front axle, the rear wheels are set at the rear end of the frame, the rear steering wheels are set on the rear wheels, an electromagnetic brake clutch is installed in the middle of the frame, and the left front wheel is fixed on the left front wheel Gear, the right front wheel steering gear is fixed on the right front wheel, the right front wheel steering gear is connected with the lower gear of the right synchronous gear set, the upper gear of the right synchronous gear set is connected with the upper gear of the left synchronous gear set, and the left synchronous gear set The intermediate gear is connected with the left front wheel steering gear, the lower gear of the left synchronous gear set is connected with the lower gear of the electromagnetic brake clutch, and the upper gear of the electromagnetic brake clutch is connected with the rear wheel steering gear; this kind of walking mechanism adopts a three-point structure , and adopts the steering method of three-wheel steering at the same time, therefore, theoretically, it can be realized that the truck can move forward in a straight line in all directions without turning the body, so as to improve the adaptability of the truck to the environment; although it claims that it can turn And it has a relatively small turning radius, but because the axes of its two front wheels are parallel lines that never intersect, it is actually impossible for the vehicle to realize that the wheel body does not touch the ground under the condition that there is a distance between the two front wheels. Turning with sliding friction occurs, that is, the real vehicle turns; moreover, the support of this kind of running mechanism is unstable; in the case of obtaining the above-mentioned ordinary truck or side truck by modification, the scope of body modification is large, and the structure Complex, costly, and difficult to change
