摘要
南阳石油机械厂研制的12×8运载车（XD60／12×8），主要用于组装120t修井机和200m钻机，其气控系统可实现油门。熄火的多点控制。熄火缸与油门缸互锁，可避免干涉。设计了行车刹车、驻车刹车和下坡缓速器，可确保行车安全。双锁间与载车、绞车摘挂机构联动，实现气路同步转换。气悬挂气控系统保证气悬桥承载恒定。百叶窗的开闭由手动开关和水温开关（自动）共同控制，使发动机始终工作在适当的水温范围。近40台12X8运载车的使用证明，气控系统工作良好。
12×8 truck (XD60/12×8) developed by Nanyang Petroleum Machinery Works is used for assembling 120t workover rigs and 2000m drilling rigs. The pneumatic control system of the tuck can realize multi-point control for the accelerator and stopping. The stopping cylinder and throttle cylinder is interlocked to avoid interference. Brakes for moving and stopping and reducer for moving downhill are designed to ensure safe moving. The pneumatic suspension control system ensures the constant bearing of the axle. Opening and closing of the radiator is controlled by the manual switch in combination with the water temperature switch to keep proper water temperature. Use of about 40 this kind of trucks shows that the pneumatic control system operates well.
