The transmission system of the bulldozer comprises an engine, a torque conversion module, a speed change module and a walking module, the engine is connected with the torque conversion module, the torque conversion module is connected with the walking module through the speed change module, the torque conversion module is arranged in a torque conversion box, and the torque conversion module comprises a torque conversion transmission shaft, a hydraulic transmission assembly and a mechanical transmission assembly. One end of the variable-torque transmission shaft is connected with the speed change module, the engine is connected with one end of the variable-torque transmission shaft through the hydraulic transmission assembly on one hand, the engine is connected with the other end of the variable-torque transmission shaft through the mechanical transmission assembly on the other hand, and the engine drives the hydraulic transmission assembly and the mechanical transmission assembly to synchronously output power to the variable-torque transmission shaft. Hydraulic transmission and mechanical transmission are combined, so that the adjustable efficiency range between the engine and the torque converter is enlarged, and bulldozers with different powers can be conveniently adapted.

    本发明提供一种推土机的传动系统,包括发动机、变矩模块、变速模块和行走模块,所述发动机与变矩模块连接,变矩模块通过变速模块连接行走模块,所述变矩模块设置在变矩箱内,变矩模块包括变矩传动轴、液力传动组件和机械传动组件,所述变矩传动轴的一端与变速模块连接,发动机一方面通过液力传动组件与变矩传动轴的一端连接,发动机另一方面通过机械传动组件与变矩传动轴的另一端连接,发动机驱动液力传动组件和机械传动组件同步对变矩传动轴输出动力;通过将液力传动和机械传动相结合,从而使得发动机与变矩器之间的可调配效率范围增大,从而便于适配不同功率的推土机。
