Wheeled off-road vehicle

Abstract

The invention relates to the technical field of vehicles, in particular to a wheeled off-road vehicle. The wheeled off-road vehicle comprises a vehicle body. A plurality of first auxiliary wheels are arranged on the vehicle body bottom surface of the vehicle body. The rotating direction of the first auxiliary wheels is the same as the rotating direction of wheels of the vehicle body, and the diameter of the first auxiliary wheels is smaller than the diameter of the wheels of the vehicle body. According to the wheeled off-road vehicle, on the basis of a traditional all-wheel drive off-road vehicle, the auxiliary wheels are additionally arranged at the vehicle body bottom surface, so that the off-road performance is remarkably improved on the premise that the high speed of the off-road vehicle is not decreased, in other words, when the vehicle travels on a soft road surface, the ground contact area of the vehicle can be enlarged through the first auxiliary wheels at the bottom of the vehicle; and when the off-road vehicle passes through a single bump, bellying can be prevented, the vehicle can pass through a low-bearing-capacity road surface, and the high-speed performance on a pavement road surface is kept. The wheeled off-road vehicle has the high-speed traveling capacity on ordinary road surfaces of traditional vehicles and can cross large obstacles.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a wheeled off-road vehicle. Background technique [0002] At present, traditional wheeled vehicles can only pass through obstacles lower than the height of the center of the wheel. On extreme roads and low adhesion roads, problems such as vehicle contact and underpinning will also occur, which limits the passability of wheeled vehicles. In order to improve the passability of wheeled vehicles, the following technologies are currently available: one is to use rocker wheel technology, that is, the wheels can be lifted like animal legs, so that obstacles like steps can be crossed, but the above-mentioned mechanism is very complicated, and Slow speed, unable to pass low load road. The second is the wheel-track conversion vehicle, which adopts crawler tracks when off-road. Although the off-road performance is improved, the structure is complicated and the high-speed performance of th...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to solve the problem that when the existing off-road vehicle is running on a road with complex road conditions, it is easy to produce bottoming or slow speed due to the limitation of the wheels, and it cannot pass through the low-load road surface and remain on the paved road surface. High-speed performance, it is difficult to achieve a good driving effect and obstacle-crossing effect
