摘　　要：为满足人们对休闲娱乐器械的更高需求,设计了一种履带式双人休闲运动车。该履带车由左右履带行走机构和驱动机构、制动系统、驾驶舱平衡滚筒等组成。左右履带行走机构为三角形立体设计;驱动机构的脚踏行走机构通过自适应随动变距传动机构带动左右履带行走机构行走,可保证在通过不平坦道路及上下坡路时,履带行走机构和驱动机构相对变化时的绝对传动距离不变;驾驶舱平衡滚筒独立悬挂在左右履带行走机构上,在坡度变化时能不断自动调整;两侧独立的制动系统设计,具有辅助转向、刹车的功能,单边使用可实现履带车的360°原地调头。试验结果表明,该履带车整车重量89.7 kg,最大载重量120 kg,最小转弯半径(360°原地调头)1200 mm,最高骑行速度7 km/h,最大爬坡角度20°,最大越障宽度400 mm。To satisfy the increasing requirements of the leisure entertainment equipment, a kind of cat- erpillar double leisure sports car was designed in this work. The caterpillar vehicles were composed by the caterpillar mobile mechanism, driving mechanism, braking system, the balance drum of cockpit and other subsidiary units. The caterpillar mobile mechanism had triangle three-dimensional design. The caterpillar mobile mechanism was driven by the feet-propelled assembly assemb of driving mecha- nism through the adaptive servo variable spacing transmission assemb. This design guaranteed the ab- solute transmission distance between the caterpillar mobile mechanism to the driving mechanism to be consistent when the vehicle went on the ruggedness or slope road. The balance roller of cockpit, which can automatically adjust continuously during the slope changes, was independent suspension on the caterpillar mobile mechanism . The braking system in both sides was designed to be independently, with the function of the auxiliary steering, braking and 360°turning when unilateral use. Test results showed that for the presented caterpillar vehicles, the whole-weight was 89. 7 kg, the maximum load was120 kg, minimum turning radius （360°in-situ turning） was 1200 mm, the highest riding speed was 7 km/h, the maximum climbing angle was 20°, and the biggest barrier width was 400 mm.
