The present invention relates to an urban vehicle for transporting large-volume, lightweight cargo, which is divided into two: a mini tractor unit and a lightweight platform semi-trailer. The two parts are coupled together by means of a fifth wheel with a kingpin, allowing the transportation of products having a high cubic coefficient, including long products. The mini tractor unit of the invention is shorter between the steer axle and the drive axle in comparison with a normal cargo transport vehicle. The distance between the steer (front) axle and the drive (rear) axle of the mini tractor unit is 1.3-1.7 times the width of the steer axle. With these proportions, the distances or measurements between the front steer axle and the rear drive axle are determined. The transmission shaft between the gearbox output and the transmission crown wheel where the drive half-axles are located is 40-60% shorter with respect to the transmission shaft of a normal vehicle, which helps to reduce the overall length of the original chassis, including elimination of the rear overhang, thereby achieving a shorter overall length in a range of between 15 and 25%.

    本发明涉及一种用于运输大体积轻重量货物的城市车辆,其被细分为两部分:微型牵引车单元和轻量半挂平台。它们通过带有主销的第五轮偶接,从而可以运输包括长形式在内的高立方系数产品。与用于运输普通类型的货物的车辆相比,本发明的微型牵引车单元在转向和驱动轴之间更短。所述微型牵引车单元的转向(前)和驱动轴(后)之间的轴距是转向轴宽度的1.3到1.7倍。通过这些比例,可以确定前转向轴和后驱动轴之间的轴距或尺寸;变速箱输出端与半驱动轴所在的传输冠轮之间的驱动轴相对于普通型车辆驱动轴短在40%至60%之间,这有助于减小原有底盘的总长度,包括消除后悬,使总长度缩短到15%到25%之间。
