| 180234000 | With means for steering all driven wheels | 9 |
| 20110083922 | OFF ROAD VEHICLE APPARATUS AND METHOD - 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. | 04-14-2011 |
| 180235000 | Comprising articulated frame and means for pivoting one portion of frame relative to other portion about vertical axis located centrally of vehicle | 2 |
| 20110198145 | High efficiency vehicle - The invention is a vehicle for ground operation that is an aerodynamic shell attached to wheels. The aerodynamic shell is shaped according to aircraft technology and it is elevated such that air flow around that shell is like air flow would be for that shell in flight. Elevation is accomplished by the attaching structure. Wheels at each side of the vehicle are arranged in wheel trains that are filled in and streamlined to form secondary aerodynamic units, with space between wheels used for equipment. This minimizes objects that would interfere with air flow. | 08-18-2011 |
| 20120000723 | HINGE ASSEMBLY FOR CONNECTING TWO VEHICLE PARTS TO A VEHICLE WITH ARTICULATED FRAME STEERING - The invention relates to a hinge assembly ( | 01-05-2012 |
| 180236000 | In a path of travel other than that produced by turning the front wheels and the rear wheels substantially equally and oppositely | 3 |
| 20080202837 | Omnidirectional Electric Wheelchair Control System - This invention refers to a wheelchair control system which enables them to move in an omnidirectional way without much effort by its user. The system is made up of a base ( | 08-28-2008 |
| 20090188740 | Steering System for Crane - A steering system ( | 07-30-2009 |
| 20110108347 | Steering System for Crane - A steering system ( | 05-12-2011 |
| 180237000 | Comprising swingable, plural-wheel-carrying axles on individual, vertical axes of pivot | 1 |
| 20110168474 | SLEWING RING DRIVE - A drive and steering unit for driving and steering a load support comprises a steering assembly, a slewing ring engaged with the steering assembly and being rotatable about an axis in response to actuation of the steering assembly, a drive assembly mounted to the slewing ring, and a drive power system coupled to the drive assembly and movable with the slewing ring. | 07-14-2011 |
| 180240000 | Including rotatable shaft extending longitudinally from wheels at one end of vehicle to wheels at other end for transmitting steering force thereto | 2 |
| 20080283323 | Transmission for four-wheel drive vehicle and four-wheel drive vehicle - Disclosed is a mechanism of a four-wheel drive vehicle, for enabling an engine and a transmission to be arranged compact by using an empty space within a body frame of the vehicle. The transmission includes a power take-off part for driving front wheels of the vehicle, and a rear reduction gear mechanism for driving rear wheels of the vehicle. The transmission and the engine are mounted on a swing arm which is supported on the body frame of the vehicle so as to be able to swing in an up and down direction. | 11-20-2008 |
| 20090032324 | VEHICLE WITH DUAL STEERING MECHANISMS - A vehicle having front and rear wheels includes a front wheel steering mechanism for providing a steering angle to a front wheel. Also, a rear wheel steering mechanism provides a steering angle to a rear wheel. The rear wheel steering mechanism has a first and second operational position; wherein the second operational position of the rear wheel steering mechanism is dependent upon the front wheel steering mechanism achieving a first predetermined steering state, preferably the steering through a prescribed angle or greater. | 02-05-2009 |
