The rear axle transmission propulsion system of the amphibious vehicle comprises a rear axle differential split shaft integrated assembly and a differential mechanism, the two output ends of the differential mechanism are connected with torsion shafts, one side of the differential mechanism is provided with a transfer case, and the two free ends of each torsion shaft are provided with lifting wheel supporting legs for changing the lowest height position of a rear transmission wheel in a transmission mode. The amphibious vehicle further comprises a water jet propeller for inputting power distributed by the transfer case, and the water jet propeller is implemented in the mode of providing direct propelling power for the amphibious vehicle to run in a waterway. The device is stable, reliable and large in torsion and has a waterway running mode, a land running mode and a land and water driving running mode, the switching principle of the three modes is simple and reliable, in the waterway running mode, the lowest height of the driving wheels can be changed by lifting the wheel supporting legs, namely, the driving wheels are lifted, resistance caused by the driving wheels in water is effectively reduced, and the driving efficiency is improved. The driving speed of the amphibious vehicle is increased, and the use effect of high compatibility in various geographical environments is achieved on the whole.
本发明公开了一种水陆两栖车的后桥传动推进系统,包括有后桥差速分轴一体总成,差速器,差速器的输出两端连接有扭力轴,差速器一侧配备有分动箱,扭力轴的两个自由端均传动有改变后传动轮最低高度位置的抬升轮支腿,还包括输入来自分动箱分配的动力的喷水推进器,喷水推进器以为水陆两栖车在水路中行驶提供直接推进动力的方式实施;本发明稳定可靠,扭力大,具备水路行驶模式、陆路行驶模式、水陆同驱行驶模式,且三个模式之间切换原理简单可靠,在水路行驶模式能够通过抬升轮支腿改变驱动轮的最低高度,也就是将驱动轮抬升,有效减少驱动轮在水中造成的阻力,加快水路两栖车的行驶速度,总体实现各种地理环境下高兼容性的使用效果。
