| 摘 要： | 为了使履带车辆的转向操作简便,并降低发动机的功率储备,在现有静液压双流差速转向装置的基础上,设计了一套与其匹配的采用方向盘操纵的控制装置,利用方向盘转角来控制两个定量马达的转速,再通过可差速传动的机械式变速箱分配到两侧驱动轮上,从而实现履带车辆双流传动装置转向期间车辆自动无级降速.通过台架空载试验测得车辆两侧驱动轮输出轴转速与方向盘转角之间的对应关系,并与理论计算仿真结果进行比较.结果表明:使用方向盘转向来实现履带车辆转向期间自动无级降速是可行的,为进一步研究方向盘操纵双流传动履带车辆转向装置提供充分可靠的理论依据.

| Abstract: | In order to make steering operation of tracked vehicle simple, and decrease power reserve of engine, a set of mechanism controlled with steering wheel was designed based on the existing hydrostatic double flow differential transmission device. The rotational speeds of quantitative motors were controlled by angle of steering wheel and then distributed to outer and inner output shafts by mechanical transmission box, which solved the problem of auto-stepless deceleration during steering. Corresponding relation between rotational speeds of output shafts and angle of steering wheel measured by bench test was compared with the theoretical result. The results show that the auto-stepless deceleration is feasible by operating steering wheel of tracked vehicles during steering, the device can meet designed requirement, and provide a basis for theoretical analysis in studying steering transmission with double flow driving tracked vehicles. |
