Automotive earth moving vehicle with segmented blade for alternating between straight and angular shapes

摘要

An automotive earth moving vehicle for civil and military applications. The blade is movable with respect to the body by two independently operable sets of fluid driven actuator sets which are in intersecting spatial relationship. Each actuator set is arranged symmetrically with respect to a vertical median plane of the blade and its actuators are in parallel spatial orientation with respect to each other. One set of actuators is designed for lifting and lowering the blade while the other set is designed to bring about oscillation and tilt. The blade comprises two segments horizontally linked to each other and is thus adapted to alternate between a dozer mode and a plough mode. Wing members may be provided for attachment to the two flanks of the blade in the plough mode. The vehicle also comprises a sensor for use in the plough mode adapted to feed the blade movement control with data on the terrain.
