Description
Technical Field
The invention relates to an all-terrain vehicle for walking in water, in particular to a water propulsion device arranged on a front vehicle and a rear vehicle.
Background
The double-body all-terrain vehicle is specially developed for complex and changeable pavements. With the upgrading of the demand and the cheap coping with more terrain conditions, the vehicle is required to have amphibious driving capability. At present, the water drive of the vehicle mainly carries out paddling by a crawler belt of a chassis part, the driving capability in water is very low in efficiency, and the water driving can only approach 5km/h at present at the fastest speed by matching, modeling and upgrading the crawler belt. In addition, some manufacturers add a fixed marine propeller to the tail of the vehicle body, and through analysis, the propulsion efficiency of the propeller is greatly reduced due to the fact that the vortex exists at the tail of the vehicle in the shape of the vehicle body, so that the fixed marine propeller is not a good solution.
In addition, the articulated neutral steering device used by the double-body all-terrain vehicle can fully improve the steering capacity of the vehicle when the vehicle runs on the land, so that the vehicle is flexible and fully activates the all-terrain running capacity, and the running direction in water can be adjusted only by means of the steering mode when the vehicle runs in water, and the vehicle posture is changed back and forth by means of the underwater snaking mode, so that the forward locking cannot be kept, and the operation difficulty and the pointing accuracy of arriving at the bank are greatly improved. Therefore, underwater driving becomes a focus of complaints of drivers, and the attention of drivers to observe underwater conditions is seriously distracted. In the actual underwater driving process, the vehicle deviates from a green area (an appointed landing point) when the vehicle is on the shore, and an obstacle is marked in the water due to the fact that the vehicle is difficult to steer in the water, so that the wading driving capacity of the vehicle is greatly reduced.

When the vehicle needs to turn in water, the rotating speed difference is realized by controlling and changing the rotating speeds of the propelling devices on the left side and the right side of the vehicle body, and even if the thrust on the left side and the thrust on the right side of the vehicle body are different, the underwater turning of the vehicle is realized.
The state of the vehicle running in water is shown in fig. 10.
