军用战斗车辆主要用于越野行驶,因此必须有一种能适应各种不同地形条件的行动装置。几十年以来已经证明履带式行动装置尤其对于较重型的越野车辆是行之有效的。履带式行动装置的一个大的优点是对地面的单位面积压力小,对于50吨的车辆,单位压力很少达到0.9公斤/厘米~2。这个数值能使覆带式车辆在松软地面上行驶,而轮式车辆在这种松软地面上就会立即抛锚。履带式行动装置的缺点是结构复杂而又笨重,车辆的采购和维修费用较高,履带的使用寿命较短。苯重当然是不理想的。目前,高机动战车的行动装置的重量约占车辆总重量的20～24％(不包括附加载荷和乘
Military combat vehicles are mainly used for off-road operation, so there must be a mobile device that can adapt to various topographical conditions. Caterpillar mobile devices have proven to be effective for heavier off-road vehicles for decades. One of the great advantages of the crawler-mounted mobile unit is that the pressure per unit area on the ground is small, and for a 50-tonne vehicle, the unit pressure rarely reaches 0.9 kg / cm 2. This value allows the belt-covered vehicle to drive on a soft ground, while the wheeled vehicle immediately breaks down on this loose ground. The disadvantages of crawler-mounted mobile devices are complex and heavy structures, high procurement and maintenance costs for vehicles, and short service lives of crawlers. Of course, benzene is not ideal. At present, the weight of mobile devices for high mobility vehicles is about 20% to 24% of the total weight of the vehicle (excluding additional load and multiplication
