4.载荷在各轴上的分配和每根轮轴最大荷重的确定现有的设计表明,对于平板全挂车各轴上的负荷应该接近相等,对于转向的前轴有时负荷略小于后轴。对半挂车由于它本身的重量和载重量中的一部分支承于牵引汽车的牵引鞍座上,另一部分支承于它的轮轴上,所以它的轴荷是决定于半挂车总重及牵引鞍座上的允许负荷。鞍式牵引车多是由某一吨位等级的载重汽车变型而来,一般说鞍式牵引车鞍座上的负荷,可以等于或略小于相应载重汽车底盘的载重量。这是因为: (1)由某一吨位等级的载重汽车变为牵引车后,必须保持原载重汽车的总重和轴荷重量;
4. Assignment of loads on each axis and determination of maximum load per wheel The existing design shows that the load on each axle of a flatbed trailer trailer should be approximately equal and the load on the steering front axle is sometimes slightly less than the rear axle. The trailer is supported on the traction saddle of the towing vehicle for part of its own weight and load and on the other hand on its axle so that its axle load depends on the total weight of the trailer and on the traction saddle The allowable load. Saddle tractor mostly by a tonnage of truck variants, generally speaking saddle tractor load on the saddle, can be equal to or slightly less than the corresponding truck chassis load. This is because: (1) After a truck of a tonnage level becomes a towing vehicle, the total weight and axle load of the original truck must be maintained;
