The upper planetary gear 16, the planetary gear 16 drives the wheel axle 9 mounted in the wheel axle housing 10. The front axle differential case 33 rotates synchronously with the front axle tapered driven gear 25, and the differential output shaft 13 follows the rear axle differential case 14 to rotate, and is decelerated by the planetary gear 16 to drive the wheel axle 9 to rotate, the front wheel Mounted on the wheel axle 9, the wheel rotates as the wheel axle 9 rotates. Similarly, the front wheel is mounted on the wheel axle 9, and the wheel also rotates as the wheel axle 9 rotates, thus forming a four-wheel drive.
本发明装载机行走传动装置， 是由变量液压马达或定量液压马达给定的 扭矩， 经过变量液压马达或定量液压马达变速箱变速后传递给后桥圆锥主动 齿轮轴， 经由圆锥主动齿轮将扭矩传递给后桥圆锥被动齿轮， 带动后桥差速 器箱体旋转， 后桥圆锥主动齿轮轴另一端通过传动轴带动前桥圆锥主动齿轮 轴旋转， 带动前桥差速器箱体旋转， 从而使前桥差速器与后桥差速器同步旋 转，前桥、后桥的差速器的输出轴通过各自的行星齿轮再减速后传给车轮轴， 从而构成四轮驱动的行走传动装置。 The loader travel device of the present invention is a torque given by a variable hydraulic motor or a quantitative hydraulic motor, and is transmitted to a rear axle cone drive gear shaft after being shifted by a variable hydraulic motor or a quantitative hydraulic motor gearbox, and torque is transmitted via a cone drive gear. The rear axle cone driven gear is driven to drive the rear axle differential case rotation, and the other end of the rear axle cone drive gear shaft drives the front axle cone drive gear shaft to rotate through the drive shaft, thereby driving the front axle differential case to rotate, thereby making the front The bridge differential rotates synchronously with the rear axle differential, and the output shafts of the differentials of the front axle and the rear axle are further decelerated by respective planetary gears and transmitted to the wheel axles, thereby forming a four-wheel drive traveling transmission device.
