The invention belongs to the technical field of lunar rover platforms and particularly relates to a wheel-track combined type high-trafficability lunar rover. The lunar rover comprises two independently-driven front wheel systems, two wheel-track switchable rear wheel systems, namely a crawler system and a rover body, wherein the crawler system comprises a crawler, a crawler main driving wheel, afront swing arm mechanism, a rear swing arm mechanism, a front guide wheel, a rear guide wheel, a front auxiliary supporting wheel and a rear auxiliary supporting wheel, the front swing arm mechanismdrives the front guide wheel and the front auxiliary supporting wheel, and the rear swing arm mechanism drives the rear guide wheel and the rear auxiliary supporting wheel to rotate around a crawler main driving wheel shaft. The lunar rover is advantaged in that a crawler belt is lifted up or put down according to working condition requirements of ground conditions, running speed and the like, sothe lunar rover has a wheel type running state and a wheel-crawler combined type running state, the grounding length of the crawler belt can be changed according to the lifting conditions of a front swing arm and a rear swing arm, by utilizing change of a running state of a running system, the smooth running requirements of the lunar rover on different running road surfaces such as ramps, bends and ditches on soft lunar soil can be met, and trafficability is high.
本发明属于月球车平台技术领域,具体涉及一种轮履复合式高通过性月球车,其包括:两个独立驱动的前轮系统、两个轮履可切换式后轮系统即履带系统、车体。所述履带系统包括履带、履带主驱动轮、前摆臂机构、后摆臂机构、前导轮、后导轮、前辅助支撑轮、后辅助支撑轮。前摆臂机构带动前导轮和前辅助支撑轮、后摆臂机构带动后导轮和后辅助支撑轮可分别绕履带主驱动轮轴旋转,根据地面情况、行驶速度等工况要求将履带抬起或放下,使月球车具有轮式和轮履复合式两种行驶状态,且履带接地长度可根据前、后摆臂抬起情况进行改变。本发明利用行走系统行驶状态变化,可以满足月球车在松软月壤上不同行驶路面如坡道、弯道、沟坎等的顺利行驶需求,通过性高。
