1.作业概况 08—32型捣固车作业走行系统采用静液压驱动,前后转向架都采用OMV630型液压马达。前转向架上的驱动轴与液压马达之间的二级机械减速比分别为3．93和 4．11,后转向架上的驱动轴与液压马达之间只有一级机械减速,其传动比为4．11, 前后转向架上的驱动轴转速比为1／4．11,
1.Operation overview 08-32 tamping car operating system using hydrostatic drive, front and rear bogies are used OMV630 type hydraulic motor. The two-stage mechanical reduction ratio between the drive axle on the front bogie and the hydraulic motor is 3.93 and 4.11, respectively, and there is only one mechanical deceleration between the drive axle and the hydraulic motor on the rear bogie. The transmission ratio is 4.11, before and after the bogie drive shaft speed ratio of 1 / 4.11,
