在重型军用汽车的传动系统中,为了提高附着能力,通常采用3个或4个驱动桥的结构。在多桥驱动系统中,一旦某一驱动桥丧失附着条件,失去牵引力,那么其它驱动桥上的驱动轮的牵引力也将受到限制,从而使汽车的越野机动能力大大降低。 为了避免这种情况发生,通常在汽车传动系统的桥问和轮间加装差速锁止装置,如4桥驱动的军 In a heavy-duty military vehicle drive system, three or four drive axles are commonly used to improve adhesion. In a multi-axle drive system, once a transaxle loses traction and loses its traction force, traction forces on other transaxle wheels will also be limited, resulting in a much lower off-road maneuverability. In order to avoid this from happening, it is common to install differential lock devices such as a bridge-driven army
