摘要
该文提出了一种具有双输出的混联式混合动力履带车辆的传动系统结构设计。该结构具有双输出轴分别连接左、右履带,通过与3排行星齿轮结构连接,可以实现两侧履带的精确独立控制,通过控制发动机工作状态,使车辆的运行效率最优,在充分保证直线行驶性能的同时,增强行进中转向能力。相比于现有的复杂混合动力履带车辆传动系统,该设计可以省去转向机构,并提升系统综合运行能力。采用自动建模的方法对所有可行结构进行动力学分析,结合不同结构类型的特点确定双模结构组合方式。通过系统特性初筛、性能精细筛选得到满足设计要求的结构。通过动态规划算法对所选结构进行典型工况下的燃油经济性分析。仿真结果表明,得到的最优方案比目前常用的串联式混合动力履带推土机具有更优的直线行驶、转向行驶和燃油经济性能。
This paper presents a powertrain design for hybrid track-type vehicles based on planetary gear sets.The design uses a three planetary gear set structure with two operating modes for the best fuel efficiency while improving the straight driving performance and the steering performance.This design eliminates the complex steering shaft while ensuring the steering index and improving steering efficiency compared with current powertrain designs.An automated modelling method is used to analyze all the candidate designs.The designs are screened using dynamic programming to analyze the fuel economy to select the best one with the least fuel consumption.Simulations indicate that the design has better performance and fuel economy than the current series hybrid benchmark for the track-type vehicle powertrain design.
