The invention discloses a hydraulically-driven self-propelled liftable high-clearance agricultural vehicle chassis which comprises a frame, a cab, an engine, four wheel assemblies and a hydraulic system, one side of a wheel seat of each wheel assembly is provided with an independent suspension system, and the top end of each suspension system is fixed to the bottom of the frame through a connecting rod; the suspension system comprises an outer stand column assembly and an inner stand column assembly which are movably connected in a sleeved mode, the bottom end of the inner stand column assembly is installed on the wheel seat, and the top end of the outer stand column assembly is connected with the connecting rod through a bolt. A lifting oil cylinder is installed between the outer side wall of the outer stand column assembly and the outer side of the wheel seat, the relative position between the inner stand column and the outer stand column is adjusted by controlling stretching and retracting of the lifting oil cylinder, then the ground clearance of the vehicle chassis is controlled, and the crop operation vehicle can be suitable for crop operation of different heights. The wheel seats and the wheel assemblies form a walking mechanism of the whole vehicle, and advancing and retreating of the chassis are achieved through hydraulic drive.

    本发明公开了一种液压驱动自走式可升降高地隙农用车辆底盘,包括车架、驾驶室、发动机、四组车轮总成和液压系统,四组车轮总成的车轮座的一侧均安装有一组独立的悬挂系统,悬挂系统的顶端通过连接杆固定在车架的底部;悬挂系统包括活动套接的外立柱总成和内立柱总成,内立柱总成的底端安装在车轮座上,外立柱总成的顶端与连接杆通过螺栓相连接;外立柱总成的外侧壁和车轮座外侧之间安装有升降油缸,通过控制升降油缸的伸缩来调节内立柱与外立柱之间的相对位置,进而控制车辆底盘的离地间隙,使得本发明能够适用不同高度的农作物作业。车轮座和车轮总成构成整车的行走机构,通过液压驱动实现底盘的前进和后退。
