摘要： A high mobility wheeled vehicle for transporting long loads, such as trimmed tree trunks or whole trees, over roadless terrain. The vehicle has front and rear quad wheel assemblies pivotally connected to a centrally disposed elongated bed frame so as to permit lateral rotation of these assemblies about a roll axis disposed below and parallel to the longitudinal axis of the bed frame. A linkage type roll control interconnects the quad wheel assemblies and the bed frame to proportionately control the relative angular movement of the bed frame with respect to the quad wheel assemblies. The roll control includes a plurality of interconnected links plus a pair of power extensible links for selectively adjusting the steady state position of the vehicle bed relative to the quad wheel assemblies in either direction.The quad wheel assembly incorporates a unique mounting for each of the wheels of the assembly which provides for individually controlled motors for driving each wheel, individually controlled brakes, and individually controlled, power actuated extensible links for steering each wheel. Sensors are provided on each wheel assembly which generate signals proportional to the rotational velocity and direction of the wheel and proportional to the turning angle of each wheel. A microprocessor receives all such signals and compares same with a desired turning angle and rotational velocity of the wheels in accordance with one of a plurality of modes of operation of the vehicle selected by the operator, and generates appropriate control signals to the individually controlled wheels to adjust the turning motion and the rotational velocity to that required to effect the desired movement of the vehicle.

摘要： The invention relates to a unique self propelled vehicle capable of transporting massive loads over natural terrain, such as the loading and transporting whole trees from their growing site to a processing station. The invention provides a vehicle having an elongated rigid frame element supported by two spaced sets of quad wheel assemblies, with each assembly permitting movement of individual wheels about both a roll axis parallel to the longitudinal frame element and a pitch axis transverse to the frame element. An operator's platform is adjustably mounted on the forward portion of the rigid frame structure for vertical movements and may carry with it a boom having means on its free end for severing and engaging whole trees or lifting massive objects to deposit same in cradles or a body mounted on the rigid frame element. Power actuated mechanisms are provided for rotating each wheel, steering each wheel, moving the operator's platform vertically to any desired position, actuating the loading boom, and tilting of the longitudinal frame element to maintain the horizontal plane of the operator's platform, to unlaod a stack of trees carried by the cradles or to lift an end of a quad wheel assembly walking beam. In the event that any wheel becomes inoperative a detachable linkage is provided to anchor the affected wheel in an elevated position as to permit the vehicle to be moved under its own power to a repair station. Power for all such operations is supplied from a power source adjustably mounted for vertical movements on the rear end of the elongated rigid frame element.

摘要： A low pressure, pneumatic tire is provided with a flexible tread belt that extends outwardly beyond the sidewalls respectively adjacent thereto when the sidewalls are flexed under normal load. The configuration and stiffness of the belt is such that the load carried by the tire is effectively spread beyond the width of the flexed torus. At the same time, local deformation of the belt can take place in such a way to fold up over the flexed sidewalls to prevent them from damage by shock or abrasion caused by objects striking the sidewalls.

摘要： A high-mobility wheeled vehicle for transporting long loads over roadless terrain. The vehicle has front and rear quad wheel assemblies pivotally connected to a centrally disposed elongated bed frame so as to permit lateral rotation of these assemblies about the longitudinal axis of the frame. A roll control means interconnects the quad wheel assemblies and the bed frame to proportionately control the relative angular movement. The wheels of each quad wheel assembly are paired together by walking beam members, thus providing a suspension system having balanced load distribution between the wheels over a wide range of terrain roughness conditions. A differential drive system provides a balanced distribution of power to each wheel on both assemblies under all wheel drive conditions. Preferably, each of these wheels is steerable and the steering control means provides for oblique travel in conjunction with conventional steering.

摘要： This invention provides an apparatus for mounting, driving and steering the wheels of a high mobility wheeled vehicle, such as those used over roadless terrain in tree harvesting operations. Each vehicle wheel is mounted on a rotatable hub which is in turn journaled on the end of a wheel drive housing. The housing is medially pivoted to the wheel suspension structure of the vehicle for steering movements and has a driving motor mounted on the inner end of the housing and connected to the wheel hub through an appropriate gearing system. The pivotal mounting of the drive housing is preferably located at the end of a walking beam arm which is disposed at a substantial horizontal angle with respect to the longitudinal axis of the vehicle to provide clearance for steering movements of the vehicle wheel. The steering motion is imparted to the drive housing by an actuator which is connected between the inner end of the drive housing and the inner end of the walking beam arm.

摘要： This invention relates to a mounting and driving mechanism for the steerable wheels of a multi-wheel, off-road vehicle of the type utilized for transporting long loads, such as trimmed tree trunks or whole trees, over roadless terrain. Such vehicles generally have front and rear quad-wheel assemblies pivotally connected to a centrally disposed elongated bed frame so as to permit lateral rotation of the quad-wheel assemblies about a roll axis disposed below and parallel to the longitudinal axis of the bed frame. Each quad-wheel assembly additionally includes a pair of walking beams which are respectively disposed in laterally spaced relationship with respect to the longitudinal bed frame and are pivotally mounted for rotation about a horizontal transverse axis. At each end of each walking beam, a wheel is mounted in a unique fashion together with individually controlled motors for respectively supplying traction power and steering movements to such wheel. A unique feature of the mounting and driving mechanism for each wheel is the fact that both the traction torque and the steering torque is transmitted to the wheel about a common axis provided in the wheel mounting housing.
