| 101 | FOUR WHEEL DRIVE SYSTEM | US12794369 | 2010-06-04 | US20100307843A1 | 2010-12-09 | T. Towles Lawson, JR. |
| A four wheel drive system for bilaterally symmetric vehicles has separate controlled drive speed and direction for each wheel. Each drive system is operable to independently drive each wheel. The rear wheels of the vehicle are steering wheels which are connected with the vehicle frame for independent rotation about a vertical axis. Steering and driving of the wheels is controlled by a controller. The combination of controlled steering for the rear wheels through many degrees about their vertical axes and individual power to all four wheels provides the vehicle with a zero turning radius for improved mobility as well as improved traction on unstable surfaces. | ||||||

The hands-free input device of the invention, which includes the position detection assembly and a position detection device, provides input signals representative of desired wheelchair movements to the controller. The position detection device detects the position of the seat. Movement of the seat, rather than a joystick, creates the voltage signals which are then transmitted to the wheelchair controller. | ||||||
| 110 | Method and device for controlling a drive system | US11711267 | 2007-02-27 | US20070219694A1 | 2007-09-20 | Norbert Krimbacher |
| The present invention generally relates to a method and a device for controlling a drive system, in particular a hydraulic traveling drive of a crane, a caterpillar, an industrial truck or a construction machine, which has at least one drive unit for an element to be driven. The invention on the one hand relates to a method, in which a desired value of an output parameter as well as a power limit value for the at least one drive unit are specified and in dependence on the specified desired value of the output parameter and the specified power limit value at least one actuating signal is provided for the at least one drive unit. The invention in particular relates to a method, in which at least two separate drive units are provided for a left drive wheel and a right drive wheel, wherein one desired speed each is provided for the two wheels and in dependence on the specified desired speeds at least one actuating signal is provided for the drive units. Furthermore, the invention relates to a control device for controlling such drive system, comprising a control signal circuit for providing an actuating signal for adjusting the at least one drive unit in dependence on a specified desired value of an output parameter as well as a specified power limit value for the at least one drive unit. Finally, the invention relates to a crane, a caterpillar or a construction machine with such a control device. On the one hand, there is proposed a control which effects an intelligent differential lock between a left drive wheel and a right drive wheel, which even during cornering prevents the driven wheels from being strained against each other and nevertheless ensures a speed coupling of the two wheels even in the case of traction problems. On the other hand, a control is proposed in accordance with a further aspect of the invention, which reliably prevents or limits a slip of a drive wheel or element and thereby increases the efficiency of the drive and reduces wear. In accordance with a first aspect of the present invention, the specified power limit value, in dependence on which the at least one actuating signal is provided for the at least one drive unit, is reduced in dependence on a matching of the specified desired value of the output parameter with a current actual value of said output parameter. If the difference between desired value and actual value of the output parameter exceeds a predetermined tolerance threshold, the power limit value is reduced correspondingly, whereby the actuating signal is corrected correspondingly. | ||||||

A drive axle arrangement for such a vehicle is also disclosed. | ||||||

| A drive system is provided for an off-road vehicle that moves across unprepared terrain such as snow, tundra or ice. A plurality of n flexible airbag tires are in contact with the terrain and are driven by n top drive rollers carried by the chassis of the vehicle which frictionally engage and drive the airbag tires.

| 114 | Tractor with hydraulic speed and steering control for steering at maximum speed | US11188293 | 2005-07-25 | US20070017712A1 | 2007-01-25 | James 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. | ||||||

| Disclosed herein are devices, systems, and methods that allow an operator to maintain the speed of a vehicle's propulsion devices at selected speeds that are less than full speed, and allow the operator to make adjustments to the selected speeds during or prior to operation of the vehicle. Disclosed embodiments can comprise adjustable limiters that are coupled to the control portion of the vehicle adjacent to or on the speed control levers. These devices can be set to a selected position to provide a stop that limits the levers to a modified maximum position that is different from the normal maximum, full-speed position. This allows the operator to hold the levers against a new limiting surface to keep the vehicle moving at a speed that is less than full speed with minimal aberration and less effort needed by the operator. The device can be adjustable to a range of positions corresponding to different speeds, and each lever can have its own limiting device to set an independent modified-maximum speed for each propulsion device of the vehicle. The devices can also be selectively pivoted or moved out of the way of the speed control levers at any time to allow the levers to have their full range of motion. | ||||||
