Abstract
Various systems and techniques for providing enhancements to bogie-equipped vehicles are described and discussed. Such systems and techniques include, for example, actively driven bogie differentials, elevated obstacle mounting techniques, worm-drive steering, parking modes using toe-in or toe-out wheel steering, speed-sensitive steering mode selection, and various other enhancements and techniques.
Claims22
An apparatus comprising:
- a first bogie that includes a corresponding bogie structure, a corresponding first axle, and a corresponding second axle;
- a second bogie that includes a corresponding bogie structure, a corresponding first axle, and a corresponding second axle;
- a chassis;
- a first pair of wheels associated with the first bogie structure;
- a second pair of wheels associated with the second bogie structure;
- a first set of one or more drive motors;
- a second set of one or more drive motors;
- and
- a controller that includes one or more processors and one or more memory devices, wherein:
- the first bogie and the second bogie are both connected with the chassis and are located on opposite sides of the chassis with the first axles of each positioned at the same end,
- each wheel in the first pair of wheels is connected with a different one of the first axle and the second axle of the first bogie,
- each wheel in the second pair of wheels is connected with a different one of the first axle and the second axle of the second bogie,
- at least one drive motor of the first set of one or more drive motors is configured to drive one of the wheels in the first pair of wheels responsive to control signals received from the controller, and
- at least one drive motor of the second set of one or more drive motors is configured to drive one of the wheels in the second pair of wheels responsive to control signals received from the controller.
