The invention discloses an elastic hydraulic track wheel with variable wheel number, which belongs to the technical field of mechanical equipment, and comprises a driving wheel, a plurality of driven wheels, a track and a hydraulic cylinder, the hydraulic cylinder comprises a main cavity and a plurality of branch cavities; a piston is arranged in each sub-cavity, a piston rod is arranged below the piston, and the driven wheel is mounted at the lower end of the piston rod; the plurality of sub-cavities comprise two curved cavities, a plurality of elastic cavities and at least one original cavity, and the corresponding driven wheels are respectively a curved driven wheel, an elastic driven wheel and an original driven wheel; the two curved cavities are located at the two ends respectively. The inner wall of the curved cavity is a curved surface, and the curved driven wheel always tensions the crawler belt; the elastic driven wheel and the original driven wheel tension the crawler belt when extending out and do not contact with the crawler belt when retracting; and an elastic piece is connected between the piston of the elastic cavity and the upper wall of the main cavity. The crawler wheel effectively solves the problems that a traditional crawler wheel is insufficient in supporting force, poor in walking stability and weak in vibration buffering capacity due to the change of road excitation.
本发明公开了一种弹性液压式轮数可变履带轮,属于机械设备技术领域,包括驱动轮、若干从动轮和履带,还包括液压缸;液压缸包括总腔体及多个分腔体;每个分腔体内均设有活塞,活塞下方设有活塞杆,从动轮安装在活塞杆下端;多个分腔体包括两个曲型腔体、若干弹性腔体和至少一个原腔体,对应的从动轮分别为曲型从动轮、弹性从动轮和原从动轮;两个曲型腔体分别位于两端;曲型腔体的内壁呈曲面,曲型从动轮始终张紧履带;弹性从动轮和原从动轮伸出时张紧履带,收缩时与履带不接触;弹性腔体的活塞与总腔体的上壁之间连接有弹性件。本发明有效解决传统履带轮因路面激励大小变化而产生的支撑力不足、行走稳定性较差以及振动缓冲能力较弱的问题。
