  • Patent number: 8985252
    Abstract: A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. Each driven wheels is driven by a hydraulic motor with a continuous adjustment of the motor displacement, with the motor being driven by a pump also having continuous displacement. The motor displacement is controlled by an electronic controller in response to stroking of the speed control lever to manage the displacement to provide required drive torques at different points in the stroke. There is provided an automatic steering system having a guidance controller arranged to receive GPS position information which controls the steering by differentially adjusting the displacement of the motors so that the automatic steering is independent of the manual steering which controls the pumps.

  • Patent number: 8960354
    Abstract: A combination structure of bicycle frame and motor hub includes a bicycle frame, a motor hub, and an elongated axle. One can extend, from one side of the bicycle frame, the elongated axle through a through hole of the bicycle frame and the motor hub, and then with one hand, a tail end of the elongated axle can be fastened into an internal thread hole of the bicycle frame. This will facilitate assembly of the components of the motor hub and the bicycle frame. Besides, when screwing or unscrewing the elongated axle, since the elongated axle has passed through the through hole and the internal thread hole opposing each other at the bicycle frame, the motor hub will not fall accidentally, and convenience can be assured for maintenance staff during proceeding of maintenance work.

  • Patent number: 8894082
    Abstract: A bicycle having rotatable drive member in the form of a hollow drum (22) with pedals (48, 49). Each pedal is mounted in a foldable manner to a crank arm (24, 25) which in turn is mounted to the drum (22) by a pivoting mechanism (26, 27) allowing the pedals to be moved between an operative configuration in which each pedal projects outwardly from the drum (22), and an inoperative configuration in which each pedal (48, 49) and each crank arm (24, 25) is contained within the interior of the drum (22).

  • Patent number: 8876138
    Abstract: The present invention provides a wheelchair device configured to reduce the likelihood that a user might fall out of a wheelchair. The device includes a wheelchair frame, a lever, and a seat cushion, whereby the seat cushion is flexible and configured to sink into a recessed and angled orientation when occupied by a user. The sunken seat cushion serves to encourage a user to attain proper posture and further serves to reduce the chances that a user might fall forward out of the seat. The lever of the present invention is attached to the underside of the wheelchair device and comprises a handle portion and a flat base portion with a curved upper surface. A forward actuation of the handle results in the lever rotating about the wheelchair, causing the base to contact and lift the seat cushion to a level that facilitates the exiting of the wheelchair device.

  • Patent number: 8875835
    Abstract: A vehicular rear wheel steering device includes a housing, a rod being non-turnable with respect to the housing and movably supported in an axial direction of the rod, and a conversion mechanism arranged between the rod and the housing to convert a rotation of a rotational drive device to a drive force in the axial direction. The housing includes a tubular first bush disposed at a first end and a tubular second bush at a second end. Each bush is slidably engaged to an outer periphery of the rod and supports the rod to be movable in the axial direction. A rod supporting rigidity of the first bush is lower compared to that of the second bush. The first bush is arranged with an elastic body that deforms in a radial direction of the rod. The second bush is arranged with an inner periphery protrusion at which the rod tilts.

  • Patent number: 8863865
    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.
