１．传动系统利勃海尔静液驱动ＰＲ７５１Ｍｉｎｉｎｇ推土机每侧履带分别由一个双向斜盘变量泵和两个变量马达组成闭式回路驱动，传动系统大大减化。液压泵与发动机飞轮分动箱直接相连接，液压马达直接与履带终传动减速器相连接。发动机转速感应功率控制系统使推土机的行...
1. Transmission system Liebherr’s hydrostatic PR751Mining dozer track consists of a two-way swashplate variable displacement pump and two variable motors, each of which consists of a closed loop drive. The drive system is greatly reduced. The hydraulic pump is directly connected with the engine flywheel transfer case, and the hydraulic motor is directly connected with the tracked final drive reducer. The engine speed induction power control system makes the bulldozer row...
