The invention belongs to the technical field of tracked vehicle transmission, and particularly relates to an integrated transmission device for braking, speed changing and steering functions of a tracked vehicle, which comprises seven planet rows, two hydraulic elements, two spiral bevel gears, eleven straight gears, six brakes, three clutches and three main transmission shafts, the input shaft is connected with the first spiral bevel gear and inputs power of the engine to the transmission device. The two output ends are connected with brakes on the two sides of the transmission device respectively, and the brakes are connected with planet row sun gears of the side speed reducers on the two sides and output power to a driving wheel. Integration of power input, a hydraulic stepless steering device, a planetary speed change device and a braking device is achieved, braking, speed change and steering functions of a rear-mounted power tracked vehicle are integrated, the power density of a transmission device is effectively improved, the stepless steering function of all gears is achieved, transmission and braking are integrally controlled, and the transmission efficiency is improved. And the braking performance, the safety, the reliability and the use maintainability of the vehicle are effectively improved.

    本发明属于履带车辆传动技术领域,具体涉及一种用于履带车辆制动变速转向功能一体化集成传动装置,包括:七个行星排、两个液力液压元件、两个螺旋锥齿轮、十一个直齿轮、六个制动器、三个离合器、三个主传动轴;输入轴和第一螺旋锥齿轮相连,将发动机的动力输入至传动装置;输出端有两个,分别与传动装置两侧的制动器相连,制动器与两侧的侧减速器行星排太阳轮相连,将动力输出给主动轮。本发明实现动力输入、液压无级转向装置、行星变速装置、制动装置的集成,实现后置动力履带车辆集成制动、变速和转向功能,有效提高传动装置功率密度,具备各档无级转向功能,传动与制动的一体化控制,有效提升车辆制动性能、安全性、可靠性和使用维护性。
