摘　　要：分析与设计了履带式作业车的行走系、传动系和操纵机构。在分析履带式作业车的行走系结构形式的基础上,运用驱动力与行驶阻力平衡方程对驱动力进行了分析与计算,为车辆发动机的选型提供依据;采用了一种液压传动与机械传动相结合的传动方式,确定了传动系的关键设计参数;操纵机构采用了集中操纵方式。履带式车辆行走系的力学分析方法适用于履带式车辆的设计与开发。液压传动与机械传动相结合的传动方式,不仅可以使发动机功率分配合理,而且可以提高车辆的操纵性能。集中式操纵杆布置形式使车辆结构紧凑。分析与设计方法已成功用于某履带式作业车辆的样机研制。Running system, energy transmission system and control mechanism of a tracked working vehicle is analyzed and designed. With analyzing the structure style of running system, drive force is formulized using the balance equation of drive force and running resistance, and the formalization of drive force will make choosing a engine for a tracked vehicle more easy. The analysis methodology is suitable to developing a tracked vehicle. Several key performance parameters of transmission system are determined, and the transmission system consists of a hydraulic static transmission （HST） and a mechanical gear transmission. The combined style of power transmission can not only be beneficial to power collocation rationally, but also be helpful to performance improvement of operation mechanism. At the same time, a tracked vehicle can be made more compact by using a kind of integrated control style of manipulation operation mechanism. The method of analysis and design has been applied successfully to a prototype developing of a tracked working vehicle.
