Soft ground vehicle walking mechanism

Abstract

The invention relates to a soft ground vehicle walking mechanism. The soft ground vehicle walking mechanism comprises a control motor, a high pressure air chamber, an electromagnetic valve, airways, driving mechanisms, springs, an inflating air cushion shoe and a deflating air cushion shoe, wherein the inflating air cushion shoe and the deflating air cushion shoe are symmetrically arranged on the left and right sides under the walking mechanism in a longitudinal direction; the closed high pressure air chamber is formed in the walking mechanism; the control motor for controlling the pressure of the high pressure air chamber is arranged at the upper end of the high pressure air chamber; the longitudinally adjustable driving mechanisms are arranged between the high pressure air chamber and the inflating air cushion shoe and between the high pressure air chamber and the deflating air cushion shoe; the inflating air cushion shoe and the deflating air cushion shoe are connected with the high pressure air chamber through airways; solenoid valves for regulating air switches are mounted on the air ways; and the springs in a stretched state are arranged in the inflating air cushion shoe and the deflating air cushion shoe. The invention is advantaged in that the soft ground vehicle walking mechanism is simply structured, the copying passing capacity of a vehicle is improved while the contact pressure of the vehicle on the soft ground is effectively reduced, the soft ground vehicle walking mechanism realizes excellent slope climbing capacity, a problem that slip, drifting and the like are easily caused due to sensitivity to wind is eliminated, the vehicle runs stably and consumes less energy.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a vehicle running mechanism on soft ground. Background technique [0002] The stability and passability of vehicles on wet and soft road conditions such as swamps and wetlands have always been one of the difficulties in the field of vehicle dynamics and control. The typical characteristics of this type of bottom surface are complex environment, low load-carrying capacity, and unevenness, so that conventional vehicles may slip, sink or even be impossible to pass through. In order to improve the passability of vehicles on this type of road, many scholars at home and abroad have developed different types of running gear and special vehicles. Relatively speaking, although ordinary air-cushion vehicles can effectively solve the trafficability of vehicles on wet and soft roads to a certain extent, their ability to profile uneven ground, adapt to the environment, and overcome obstacles is po...
