A planetary vehicle variable active suspension mechanism

Abstract

The invention relates to a variable active suspension mechanism for a planetary vehicle, which belongs to the field of suspension design for a six-wheeled planetary vehicle; it includes two suspension structures, a vehicle body, a main shaft and a differential mechanism; the main shaft is horizontally arranged in the middle of the vehicle body; The moving mechanism is fixed in the axial middle of the main shaft; the axial ends of the main shaft extend out of the car body; two suspensions are symmetrically arranged on both sides of the car body; the suspension structure includes front wheels, front main rocker arms, angle adjustment Mechanism, middle wheel, rear main rocker arm, telescopic mechanism, clutch, auxiliary rocker arm and rear wheel; the angle adjustment mechanism is connected; the front main rocker arm is docked with the angle adjustment mechanism; the front is installed at the bottom of the front main rocker arm; The rear main rocker arm is docked with the angle adjustment mechanism; the clutch is connected with the axial bottom end of the rear main rocker arm; the middle part of the auxiliary rocker arm is connected with the clutch; the middle wheel and the rear wheel are connected with the bottom of the auxiliary rocker arm; the telescopic mechanism is set horizontally On the auxiliary rocker arm; the suspension mechanism of the present invention has high passability, and still has strong mobility after a wheel failure.

Description

technical field [0001] The invention belongs to the field of suspension design of a six-wheel planetary vehicle, and relates to a variable active suspension mechanism of a planetary vehicle. Background technique [0002] The driving environment of the planetary vehicle is relatively harsh, and it does not have the capability of on-orbit maintenance. It needs to have high passing capacity, sinking and escape ability, and it still has high mobility by lifting the wheel in the event of a wheel failure. The existing planetary vehicle suspension mechanism is mainly based on the rocker suspension of the American Spirit planetary vehicle. The suspension is hinged by a main rocker arm A and an auxiliary rocker arm B, and its suspension structure is as follows: figure 1 shown. The main rocker arm A of the suspension is connected with the front wheel D, the auxiliary rocker arm B is connected with the middle wheel E and the rear wheel F, and the left and right suspensions are respec...

AI Technical Summary

Problems solved by technology

Therefore, although the active suspension has the function of lifting the wheel, the movement ability after the wheel is lifted is greatly reduced, which cannot meet the ability requirements for driving on Mars' complex terrain.
