摘要： A working vehicle has an undercarriage assembly configured to drive the working vehicle over ground and a chassis connected to the undercarriage assembly through a suspension system. The suspension system includes a mechanical spring, the mechanical spring having a first end connected to the undercarriage assembly and a second end. The suspension system includes a hydraulic cylinder, the hydraulic cylinder having a first portion that mounts to the second end of the mechanical spring and a second portion that connects to the chassis such that the mechanical spring and hydraulic cylinder are arranged in series between the undercarriage assembly and the chassis to modify the height of the chassis. The suspension system is configured to level the chassis to offset the effects of ballast weights or other external loads such as from a drawbar or 3-point hitch.

摘要： A suspension system includes a swing arm having an end engaging a framework of a vehicle, an end engaging skid rails for a track. A front link has an end engaging the framework and a second end. The first end engages. A middle link has a end joined to the second end and a front portion of the swing arm, and a shock end. A shock has a end joined to the shock end, and a rail end engaging the skid rails. The front link, middle link and shock enable a rising rate system. A rear arm has an end engaging the framework, an end engaging a rear portion of the skid rails, and a length approximately a length of the swing arm. The rear arm is positioned approximately parallel to the swing arm during a travel range of the suspension system for controlling an orientation of the skid rails.

摘要： The present invention relates to a caterpillar track wheel with division of work between track and chain, methods for fitting unit track with flexible chain ring, methods for buffering prestress, and an open-dose type axle housing. Since a structure that each unit track is separated from a flexible chain ring is adopted, the thickness of the unit tracks does not influence the winding stress of the flexible chain ring and the unit tracks without thickness limitation can effectively disperse stress from the ground to more supporting wheels. Since the thinner flexible chain ring is only responsible for serially connecting the unit tracks and transmitting power, the winding stress and the tension change are reduced.
