The invention discloses a hydraulic system of an amphibious vehicle. The hydraulic system comprises a hydraulic oil tank and a plurality of track driving branches. Each track driving branch comprises a gear pump, a control valve and a track rotating mechanism, and the hydraulic oil tank outputs hydraulic pressure to the track rotating mechanisms after sequentially passing through the gear pumps and the control valves. The track rotating mechanisms are driven by the hydraulic pressure to drive the track to rotate. The control valve is used for receiving a signal of the whole vehicle controller to be opened and closed. Each gear pump is connected with an engine, and the engine outputs power to drive the corresponding gear pump to rotate. The hydraulic system of the amphibious vehicle has the advantages that the hydraulic system is adopted to drive the track to rotate, safety and reliability are achieved, meanwhile, the whole vehicle operation power is provided in the way of the track and wheels, and the device can be better adapted to various responsible driving working conditions. And meanwhile, hydraulic heat dissipation control is achieved through hydraulic heat dissipation, heat dissipation of oil can be effectively controlled, and it is guaranteed that the temperature of the oil hydraulic system is kept at a safe position.

    本发明公开了一种水陆两栖车的液压系统,包括液压油箱以及多路履带驱动支路,每路履带驱动支路包括齿轮泵、控制阀、履带转动机构,所述液压油箱依次通过齿轮泵、控制阀后输出液压至履带转动机构,用于通过液压驱动履带转动机构带动履带转动,所述控制阀接收整车控制器的信号来打开关闭;所述齿轮泵与发动机连接,所述发动机输出动力带动齿轮泵转动。本发明的优点在于:采用液压系统来驱动履带的转动,安全可靠,同时以履带和车轮两种方式来提供整车运行动力,可以更好的适应各种负责的行驶工况;同时通过液压散热来实现对于液压的散热控制可以有效地控制油液的散热,保证油液液压系统的温度保持在安全位置。
