针对普通双履带车辆连续垂直障碍攀越能力的局限性,提出了一种四履带串联式行走机构,该履带机构通过一对同步的液压缸控制,能够使同侧的两条铰接履带产生相对转动,便于整车攀越具有一定高度的连续垂直障碍。借助多体动力学分析软件对普通履带和四履带串联式行走机构进行了动态分析和仿真。结果表明:四履带串联式行走机构的驱动力矩、张紧力等参数明显优于双履带。采用四履带串联式行走机构的车辆液压驱动马达的冲击负载较小。在攀越同等高度的垂直障碍时,四履带串联式车辆的倾斜度更小,驾驶舒适度更高。
Aiming at the limitation of continuous vertical obstacle-climbing ability of double-track vehicles, a four-track tandem traveling mechanism is proposed, which is controlled by a pair of synchronized hydraulic cylinders to make the two articulated tracks on the same side rotate relative to each other , For the vehicle to climb a continuous vertical barrier with a certain height. With multi-body dynamics analysis software, the dynamic analysis and simulation of common track and four-track tandem walking mechanism were carried out. The results show that the parameters such as driving torque and tension of four crawler tandem traveling mechanism are obviously superior to those of double crawler track. The vehicle hydraulic drive motor with four-track tandem traveling mechanism has a small impact load. Four-caterpillar tandem vehicles have less inclination and greater driving comfort when climbing the same vertical obstacles.
