摘要： A work vehicle includes left and right track assemblies, each track assembly having a main frame, a pivot member, a pivot shaft coupled to the pivot member, and an electrical actuator coupled between the pivot shaft and the main frame. The work vehicle also includes a control system having a controller communicatively coupled to each electrical actuator of the track assemblies. The controller includes processors that control the electrical actuator to steer the work vehicle about a generally vertical steering axis. Each pivot member is mounted to the main frame of the track assemblies. Each track assembly is pivotal about a generally horizontal pitch axis of the pivot shaft to permit pitch movement of the track assembly. Each track assembly is pivotal about a generally horizontal camber axis through a portion of the pivot member to permit camber movement of the track assembly.

摘要： A two track tractor with an active suspension system for reducing pitch jerk and a method of operation thereof utilizes a position sensor between a nose of the tractor and a front axle assembly connected to a forward rolling element. The gap between the nose and the front axle is continually measured and an average gap value is produced. An active suspension system is controlled by a microprocessor to vary the pitch angle between the tractor body and the axle assembly in order to maintain a target nose gap while limiting the pitch jerk experienced by the operator.

摘要： An automotive construction machine, in particular a slipform paver or a road milling machine, has at least one front running gear and one rear running gear in the working direction. As the construction machine advances, the lifting systems of the front running gear are extended or retracted such that the machine frame remains in a predetermined orientation to the surface of the ground in the longitudinal direction. Irregularities in the ground surface are detected as the construction machine advances, and the position of the front lifting systems, predetermined by the control or regulating unit, is monitored to keep the machine frame in a predetermined orientation to the ground surface. As the construction machine advances, the control of the rear lifting systems is engaged with a time delay subject to the control of the front lifting systems. Consequently, the working system of the construction machine, in particular the concrete mold or milling drum, is adjusted to the correct height with respect to the ground surface, so that the working system does not copy the course of the ground.
