Abstract

The invention relates to a turning driving front axle of a cross country vehicle. The turning driving front axle comprises a front axle housing, a front main speed reducer arranged in the middle of the front axle housing, two front half shafts, two turning joints and two wheel edge input shafts, wherein one of the ends of the two front half shafts is connected in match with the front main speed reducer, and while the other ends of the two front half shafts are respectively connected with wheel hubs through splines; the two turning joints are connected to two ends of the front axle housing respectively and connected in match with the other ends of the two front half shaft; and the two wheel input shafts are connected in match with the two turning joints respectively. The turning driving front axle is characterized in that the front main speed reducer is a single-grade speed reduction mechanism with the speed ratio ranged from 1.208 to 2.727; and a front wheel side driving device is respectively connected in match with each of the wheel side input shafts at two ends. According to the turning driving front axle of the cross country vehicle, the front wheel side driving devices, and driving gears and driven gears in the main speed reducer are novelly designed, thus, the turning driving front axle is compact in structure and reliable in performance, and effectively solves the problem that a current heavy vehicle axle cannot synchronously achieve the dynamic property, the fuel economy and the generality under a special working condition.

Description

technical field [0001] The invention relates to automobile components, in particular to a steering drive front axle of an off-road vehicle. Background technique [0002] At present, there are still some technical problems in the 10T single-stage deceleration off-road vehicle axle. The main difficulty lies in how to carry out the structural design of the axle so that it can meet its power requirements while having good fuel economy and passability. . With the development of heavy-duty vehicle technology, the performance requirements of heavy-duty vehicles are also getting higher and higher. The car designed according to the different environments and working conditions of the vehicle must not only ensure that it has sufficient power, but also ensure that it has good mobility. [0003] The existing single-stage deceleration off-road vehicle axle has a large speed ratio, and the corresponding basin tooth diameter is large, and its axle and axle package is large, so the passin...
