对于地面机动发射的导弹,目前国外主要选择三种运输发射车,即拖车(半拖车)、轮式自行车辆和履带式自行车辆。拖车(半拖车)比较容易满足导弹发射装置的布局要求,而且成本低,易于制造.但是机械性和越野性能比不上自行车辆。因此对机动性要求较高的导弹,一般部不选用拖车(半拖车)。然而,在自行车辆中,轮式车比履带车,有结构简单、工作可靠、寿命长、行驶 At present, three kinds of transport launchers, namely trailers (semitrailers), wheeled bicycles and tracked bicycles are mainly selected for launching missiles on the ground. Trailers (semi-trailers) are relatively easy to meet the layout requirements of missile launchers, but also low cost, easy to manufacture.But the mechanical and off-road performance than the bike. Therefore, the higher maneuverability of missiles, generally do not use the trailer (semi-trailer). However, in a bicycle, wheeled vehicles are more compact than tracked ones, have a simple structure, work reliably, have a long life, and travel
