一、概述轮胎式车辆和机械具有运行速度高、机动灵活、调度方便、结构轻巧等特点,应用非常广泛。1960年全世界轮胎的总产量为两亿套(三—6)。其中:美国11,984万套,载重用占11.51%,即约1,380万套;苏联1,720万套,载重用占69.2%,即约1,190万套;英国1,600万套,载重用占18.3%,即约293万套。轮胎式车辆和机械品种之多、产量之大、应用之广,是任何其他形式的车辆和机械所不能比拟的。
I. Overview Tire-type vehicles and machinery have features such as high operating speed, flexible maneuverability, convenient dispatch, and light weight, and are widely used. In 1960, the total volume of tires in the world was 200 million (three to six). Among them: the United States, 11,984 million units, carrying 11.51% of the load, that is about 13.8 million units; the Soviet Union, 17.2 million units, carrying capacity of 69.2%, that is about 11.9 million units; the United Kingdom, 16 million units, carrying capacity of 18.3%, or about 293 Million sets. The large number of tire-type vehicles and machinery, large output, and wide application are unmatched by any other types of vehicles and machinery.
