The invention relates to a hydraulic auxiliary drive axle and a vehicle. The hydraulic auxiliary drive axle comprises a main speed reducer and a hydraulic drive assembly. By arranging the hydraulic driving assembly, the driving capacity of the vehicle under the starting or severe working condition is effectively enhanced, and the overall performance and operation reliability of the vehicle are effectively improved; by arranging the main speed reducer, the structure is compact and simple compared with a traditional all-wheel drive while efficient output of axle power and the timely driving capacity are guaranteed, the number of parts is remarkably reduced, and therefore the manufacturing cost of a vehicle with the all-wheel drive function requirement is effectively reduced; by arranging the actuator, power disconnection or combination is achieved, the timely driving function of the axle is guaranteed, an additional power source is not needed for driving when auxiliary driving is not needed, and therefore the fuel economy of a vehicle is effectively improved while the driving performance of the vehicle is guaranteed.
本发明涉及一种液压辅助驱动车桥及车辆,包括主减速器、液压驱动组件;本发明通过设置液压驱动组件,有效增强车辆在启动或恶劣工况下的驱动能力,有效提升了车辆的整体性能以及运行可靠性;通过设置主减速器,在保证车桥动力高效输出和适时驱动能力的同时,相对传统全驱而言其结构紧凑、简单,零部件数量得到显著减少,进而有效降低了有全驱功能需求的车辆制造成本;通过设置动作器实现动力断开或者结合,保证了车桥的适时驱动功能,无需辅助驱动时则无需额外的动力来源予以驱动,从而在保证车辆驱动性能的同时,车辆的燃油经济性得到了有效改善。
