The invention discloses a wheel-side hydraulic drive walking system and a cotton picker. The wheel-side hydraulic drive walking system comprises an engine, a hydraulic pump, a front wheel motor, front wheels, a rear wheel motor and rear wheels; the engine is in transmission connection with the hydraulic pump, a first connector of the hydraulic pump communicates with a first connector of the front wheel motor and a first connector of the rear wheel motor, and a second connector of the hydraulic pump communicates with a second connector of the front wheel motor and a second connector of the rear wheel motor; when gear shifting of the vehicle is needed, the displacement of the hydraulic pump, the displacement of the front wheel motor and the displacement of the rear wheel motor are increased and decreased; when the vehicle moves forwards or backwards, oil of the hydraulic pump is output through the first connector or the second connector of the hydraulic pump so as to drive the front wheel motor and the rear wheel motor to drive the front wheels and the rear wheels to move forwards or backwards. Gear shifting is controlled through hydraulic pressure, the load of a drive axle is improved, and harvesting machinery can develop towards heavy load and large scale. In addition, parking gear shifting is avoided, and the gear shifting efficiency is improved.

    本发明公开了一种轮边液压驱动行走系统及采棉机,轮边液压驱动行走系统包括发动机、液压泵、前轮马达、前轮、后轮马达和后轮;发动机与液压泵传动连接,液压泵的第一接口分别与前轮马达的第一接口及后轮马达的第一接口连通,液压泵的第二接口分别与前轮马达的第二接口及后轮马达的第二接口连通;当需要车辆换挡时,增减液压泵的排量、前轮马达的排量和后轮马达的排量;当车辆前进或者后退时,液压泵的油液分别经过液压泵的第一接口或者第二接口输出,以驱动前轮马达及后轮马达分别带动前轮及后轮前进或者后退。本发明通过液压控制换挡,提高了驱动桥载重,使得收获机械能够向重载大型化发展。此外,避免了停车换挡,提高了换挡效率。
