| 147 | Tracked vehicle | US11702596 | 2007-02-06 | US20080128183A1 | 2008-06-05 | Ryan Fairhead |
| The present invention is an improved personal tracked vehicle consisting of a platform pivotally mounted on top of a housing, the platform having a right and left side and a central axis. The platform is pivotally movable between a first position wherein the right side of the platform is below the left side of the platform and a second position wherein the left side of the platform is below the right side of the platform. The platform has a forward portion, a rearward portion and middle portion between the two, the middle portion being arched upwardly. The vehicle further includes a pair of parallel right and left tracks mounted to the housing below the platform, the right track being coupled to a right track transmission and the left track being coupled to a left track transmission, the right and left track transmissions both being coupled to a motor for driving the transmissions. The right and left track transmissions are operatively coupled to the platform such that when the platform is pivoted towards its first position, the left track is driven faster and the right track is driven slower, and when the platform is pivoted towards its second position, the right track is driven faster and the left track is driven slower, the platform being biased towards a central position wherein the left and right drives operate at the same speed. The motor of the vehicle is mounted to the housing below the middle portion of the platform and between the tracks. | ||||||
| 148 | CONTROLLER SENSE INVERTER FOR POWERED VEHICLES HAVING A ROTATING TURRET | US11929386 | 2007-10-30 | US20080119985A1 | 2008-05-22 | Edward D. Schubitzke |
| A rotating turret vehicle having steering controls in the turret, has the sense of those controls reversed when the turret faces to the rear of the vehicle. Thus, when the operator faces the rear of the vehicle due to turret rotation, the sense of the controls are reversed so he or she operates the controls as when facing forward. Pushing a lever forward to cause forward vehicle movement when facing forward, causes reverse movement when facing backward. | ||||||
| 149 | Tractor with hydraulic speed and steering control for steering at maximum speed | US11188293 | 2005-07-25 | US07306062B2 | 2007-12-11 | James Thomas Dunn |
| A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. It can be driven cab forward in a working mode with a header on the forward end. It is rotated to engine forward in the transport position for more stable higher speed travel. The driven wheels are driven by hydraulic motors each having their own drive pump the output of which is controlled by a cam plate. The speed control is effected by a manually operable lever through a servo-cylinder which locates a speed control arm moving both cam plates to the set position. In a maximum speed position both cam plates are engaged against a stop. The steering is effected by moving the cam plates differentially to drive the wheels at different speeds. The piston rod of the servo-cylinder includes a spring relief so that the speed control arm can back off from the maximum position by moving the servo-cylinder body when steering in the maximum speed position. | ||||||
