  • Patent number: 7850180
    Abstract: A suspension system for a vehicle is provided that allows for the vehicle body to be tilted wherein the tilt is controlled by the operator's legs in a manner that greatly enhances the stability of the vehicle while producing a fun vehicle to operate. Generally a hub is provided for use ad the vertical members in a four-bar suspension linkage that includes an inboard side and an outboard side such that the tilting pivots are positioned inboard and the steering pivots are positioned outboard. This arrangement allows for the optimum placement of the pivot axis for steering as close to the wheel as possible, even directly within the rim of the wheel, while the pivot point of the suspension linkage is optimally positioned a few inches inboard relative to the wheels thereby increasing the lever arm used to control the relative tilt of the wheel.

  • Patent number: 7793742
    Abstract: A ground engaged vehicle includes a front portion and a rear portion joined by an articulation. The articulation rotates around a longitudinal axis. An engine drives a hydrostatic pump which drives four hydrostatic motors, each of the hydrostatic motors in operative engagement with one of four wheels. The wheels are on wheel mounts, each of the wheel mounts having a vertical axis around which one of the four wheels with one of the hydrostatic motors is turnable. A steering system turns the two wheels of the front portion in a first direction and the two wheels of the rear portion in an opposite direction. The steering system is powered by the hydrostatic pump. A pedal control system has a first pedal controlling driving the vehicle in a forward direction and a second pedal controlling driving the vehicle in a rearward direction.

  • Patent number: 7740254
    Abstract: A wheeled work machine in which the center of gravity of a machine body is positioned low and the stability of the machine in a working position is secured without regard to the movement of the center of gravity caused by the rotation of a rotation table during work. An operation body (111) integrally rocking with a front axle case (96) is provided at the center in the left-right direction of the front axle case (96), and a rocking lock mechanism (112) for limiting the rocking of the operation body (111) is provided at a machine body frame (6). The rocking lock mechanism (112) has a lock cylinder (115) in which a piston rod (120) is horizontally fixed to the machine frame (6) and a switchover valve (118) for switching two oil chambers (124A, 124B) of the lock cylinder (115) between a communicated state and a closed state. A cylinder tube (116) of the lock cylinder (115) is operably connected to the operation body (111).

  • Patent number: 7722063
    Abstract: A suspension system for a tilting vehicular chassis based on more than three wheels separates a tilting component of the chassis from a non-tilting component. The non-tilting component provides a means for powering the vehicle with automotive-type engine and drive train options, while the tilting component provides the turning stability necessary for a narrower wheel base. The narrower wheel base benefits fuel economy. The multiplicity of wheels, and the breadth of platform thus enabled, permits shelter and comfort features for the occupant not otherwise available on a typical two-wheel chassis.

  • Patent number: 7703781
    Abstract: A low profile chassis and suspension system for a road vehicle. The chassis supports a payload section or cargo compartment, such as for a delivery truck, ambulance, or shuttle bus. The chassis includes a largely planar frame having a top surface which is located beneath the rotational axes of the rear wheels. The wheel suspension system is particularly compact and close to the road surface. In some embodiments each wheel is suspended from the vehicle by a pair of pivotal support arms. Preferably, one arm is located above the other arm, and both arms pivot along pivot axes that are generally perpendicular to the rotational axis of the supported wheel. A spring urges one of the arms apart from the frame. In other embodiments, the spring is placed beneath the rotational axis of the wheel. In some embodiments both of the pivoting support arms are located beneath the rotational axis of the wheel.
