Problems solved by technology

[0004] However, in the traditional wheeled driving system, the wheelbase cannot be changed. The fixed wheelbase makes the pressure ratio of the body weight distributed to each axle constant, and the position of the center of gravity of the vehicle cannot be actively adjusted according to the driving needs, which affects the traffic of the mobile platform. Ability and Mobility

Abstract

The invention discloses a multi-wheel movable platform with a variable axle distance. The multi-wheel movable platform comprises a frame, at least three pairs of wheel type walking mechanisms are mounted on the frame, each wheel type walking mechanism comprises a main pin and wheels, the main pins are mounted on the inner sides of the wheels, and each pair of wheel type walking mechanisms is symmetrically arranged on the two sides of the frame. Active suspensions are mounted between the wheel type walking mechanisms and the frame, and the wheel type walking mechanisms are connected with the frame through the active suspensions. An intermediate axle moving assembly for driving the axle distance to change is further mounted on the frame, and connected with the two active suspensions locatedin the middle of the movable platform. The multi-wheel movable platform has the advantages that the structure is simple, the axle distance can be adjusted according to the road surface condition, andthen the overall mobile ability of a car is improved.

Description

technical field [0001] The invention mainly relates to the field of ground mobile platforms, in particular to a multi-wheeled mobile platform with variable wheelbase. Background technique [0002] The wheeled traveling mechanism has low driving resistance, low noise, good steering performance and high mobility, so it is widely used in various high mobility mobile platforms, including various types of cars and special vehicles. The quality of the wheeled walking mechanism will directly affect the passability and maneuverability of the mobile platform. [0003] At present, the wheeled running mechanism used in automobiles and special vehicles is mainly distributed on the left and right sides of the car body. Automobiles mainly have four wheels, and special vehicles mostly have six wheels or more. Every two wheels are a group, connected by the axle, and the axle is connected with the frame (or body) by the suspension, and the wheels, the axle, the suspension and the frame (bod...
