The liftable rear suspension system of the amphibious vehicle comprises a differential mechanism and a brake disc, the differential mechanism is installed in a vehicle body frame, the brake disc is installed on the inner side of a wheel hub, a brake is arranged on the outer edge of the brake disc, a flange plate is fixed to the inner side of the brake disc, and the flange plate is connected with the differential mechanism. A universal joint arm is rotationally installed on the periphery of the end, close to the vehicle body frame, of the flange plate through a bearing, the flange plate is connected with an output shaft of the differential mechanism through a ball cage universal joint, and a worm wheel is further rotationally installed on the periphery of the end, extending out of the vehicle body frame, of the output shaft through a bearing. A worm is rotationally connected between the pair of bearing seats, the worm is connected with the worm gear in a meshed mode, and a first double-fork arm and a second double-fork arm are hinged between the universal joint arm and the worm gear respectively. The wheel is lifted through rotation of the worm gear and the universal joint arm, so that enough ground clearance is provided, and the passing requirement of a vehicle under complex terrains is met.

    本发明公开了一种水陆两栖车可升降后悬架系统,包括差速器和制动盘,所述差速器安装在车身架内,所述制动盘安装在车轮轮毂内侧,所述制动盘的外边缘设有制动器,且制动盘的内侧固定有法兰盘,所述法兰盘靠近车身架的一端外围通过轴承转动安装有万向节臂,所述法兰盘与差速器的输出轴间通过球笼万向节进行连接,所述输出轴伸出车身架的一端外围还通过轴承转动安装有蜗轮,所述车身架上通过安装架安装有一对轴承座,该对轴承座间转动连接有蜗杆,且蜗杆与蜗轮啮合连接,所述万向节臂与蜗轮之间分别铰接有双叉臂一和双叉臂二。本发明通过蜗轮和万向节臂旋转,对车轮进行升降,以便于提供足够的地面间隙,满足车辆在复杂地形下的通过要求。
