The invention relates to the technical field of vehicle chassis, and discloses a deformable crawler chassis. The deformable crawler chassis comprises a main frame and an auxiliary frame, four transverse polish rods are symmetrically arranged on the front portion and the rear portion of the main frame, and transverse sliding bushes are installed in bushing seats at the ends of the auxiliary frame and slide on the transverse polish rods. The inner side of the auxiliary frame is connected with the transverse folding and unfolding mechanism through a hinge pin, and the hydraulic cylinder drives the transverse folding and unfolding mechanism to do folding and unfolding motion in the width direction of the vehicle body and drives the auxiliary frame to slidably stretch out or retract along the transverse polish rod. The auxiliary frame is provided with a longitudinal sliding bushing which is connected with a lifting suspension guide polish rod, the outer side of the lower end of the lifting suspension is provided with a track connecting plate which is connected with a track inner box wall through a bolt group, and the vertical lifting movement of the lifting suspension can adjust the ground clearance of the main frame and the auxiliary frame; according to the deformable tracked vehicle chassis, symmetric folding and unfolding of the vehicle body can be completed through the single hydraulic cylinder, the heights of the main frame and the auxiliary frame are adjustable, flexible adaptation to various garden maintenance operation machines and tools and operation specifications is achieved, and the cost of the garden maintenance machines and tools is effectively reduced.

    本发明涉及车辆底盘技术领域,公开了一种可变形履带车底盘。所述可变形履带车底盘包括主副车架,主车架前后对称布置有四条横向光杆,副车架端部衬套座内装有横向滑动衬套在横向光杆上滑动;所述副车架内侧通过铰链销与横向折展机构连接,液压缸驱动横向折展机构沿车体宽度方向折展运动,带动副车架沿横向光杆滑动伸出或收回;所述副车架设有纵向滑动衬套与抬降悬挂导向光杆连接,抬降悬挂下端外侧有履带连接板通过螺栓组与履带内箱壁连接,抬降悬挂垂直抬降运动可调整主副车架离地高度;本发明的可变形履带车底盘可通过单液压缸完成车体对称折展,主副车架高度可调,实现对多种园林养护作业机具及作业规格灵活适配,有效降低园林养护机具成本。
