The invention discloses a contracting and expansion type wheel track walking device which comprises a main crawler walking unit, a front auxiliary crawler walking unit, a rear auxiliary crawler walking unit, a walking frame, a left crank and a right crank. A wheel A of the main crawler walking unit is installed on a pin joint base of the walking frame through a pin shaft, and a wheel D of the crawler walking unit is supported on the ground. A wheel C of the front auxiliary crawler walking unit is in pin joint with a wheel B of the main crawler walking unit through the left crank; a wheel A ofthe front auxiliary crawler walking unit is in pin joint with the left sliding block through a connecting rod; the wheel B of the rear auxiliary crawler walking unit is in pin joint with a wheel C ofthe main crawler walking unit through the right crank; and the wheel A of the rear auxiliary crawler walking unit is in pin joint with the right sliding block through a connecting rod. The device is simple in structure, conventional wheel-type ground traveling can be achieved in a contraction state, and crawler traveling tasks of bumpiness, paddy fields, muddy fields, snowfields and other complexgrounds can be completed in an expansion state.

    本发明公开了一种收缩展成式轮履行走装置,包括:主履带行走单元、前副履带行走单元、后副履带行走单元、行走架、左曲柄及右曲柄;所述主履带行走单元的轮A通过销轴安装在行走架的销接座上,所述履带行走单元的轮D支撑在地面上;所述前副履带行走单元的轮C通过左曲柄与所述主履带行走单元的轮B销接;所述前副履带行走单元的轮A通过连杆与所述左滑块销接;所述后副履带行走单元的轮B通过右曲柄与所述主履带行走单元的轮C销接;所述后副履带行走单元的轮A通过连杆与所述右滑块销接;本发明结构简单,不仅能够在收缩状态下实现常规轮式地面行驶,而且能够在展成状态下完成崎岖不平、水田、泥泞和雪地等复杂地面的履带行驶任务。
