Abstract
A vehicle including a plurality of truck assemblies is provided. Each truck assembly includes a truck axle, a first wheel fixed to the truck axle, a second wheel selectively coupled to the truck axle, a motor configured to rotate the truck axle, and a clutch operatively coupled to the second wheel. The clutch is positionable between a coupled position and a decoupled position. When the clutch is in the coupled position, the second wheel rotates with the truck axle, and when the clutch is in the decoupled position, the second wheel is free to rotate relative to the truck axle.
Claims13
A vehicle comprising:
- a plurality of truck assemblies, each truck assembly comprising:
- a truck axle;
- a first wheel fixed to the truck axle;
- a second wheel selectively coupled to the truck axle;
- a motor configured to rotate the truck axle;
- and
- a clutch operatively coupled to second wheel, the clutch being positionable between a coupled position and a decoupled position;
- a frame comprising a front rail, a rear rail, and a first side rail extending between the front rail and the rear rail;
- a rear yoke rotatably coupled to the rear rail and rotatable relative to the rear rail about a vehicle longitudinal axis;
- and
- a linkage assembly extending between the rear yoke and the plurality of truck assemblies mounted to the rear yoke, the linkage assembly comprising:
- a first pair of tie rods extending between the first side rail and a first end of the rear yoke;
- and
- a second pair of tie rods extending between the first side rail and a second end of the rear yoke,
- wherein when the clutch is in the coupled position, the second wheel rotates with the truck axle, and when the clutch is in the decoupled position, the second wheel is free to rotate relative to the truck axle.
A method comprising:
- receiving, at a vehicle, a first instruction to perform a first maneuver, the first maneuver including moving the vehicle in a vehicle longitudinal direction, the vehicle comprising:
- a plurality of truck assemblies, each truck assembly comprising:
- a truck axle;
- a first wheel fixed to the truck axle;
- a second wheel selectively coupled to the truck axle;
- a motor configured to rotate the truck axle;
- and
- a clutch operatively coupled to the second wheel, the clutch being positionable between a coupled position to rotate the second wheel with the truck axle, and a decoupled position to permit the truck axle to rotate without rotating the second wheel;
- a frame comprising a front rail, a rear rail, and a first side rail extending between the front rail and the rear rail;
- a rear yoke rotatably coupled to the rear rail and rotatable relative to the rear rail about a vehicle longitudinal axis;
- and
- a linkage assembly extending between the rear yoke and the plurality of truck assemblies mounted to the rear yoke, the linkage assembly comprising:
- a first pair of tie rods extending between the first side rail and a first end of the rear yoke;
- and
- a second pair of tie rods extending between the first side rail and a second end of the rear yoke,
- in response to receiving the first instruction, positioning the clutch into the coupled position;
- performing the first maneuver;
- receiving, at the vehicle, a second instruction to perform a second maneuver, the second maneuver including moving the vehicle in a non-vehicle longitudinal direction;
- in response to receiving the second instruction, positioning the clutch into the decoupled position;
- and
- performing the second maneuver.
A vehicle comprising:
- a plurality of truck assemblies, each truck assembly comprising:
- a truck axle;
- a first wheel fixed to the truck axle;
- a second wheel selectively coupled to the truck axle;
- a motor configured to rotate the truck axle;
- and
- a clutch operatively coupled to second wheel, the clutch being positionable between a coupled position and a decoupled position;
- a lifting assembly including a plurality of lifting devices positionable between a lowered position and a raised position,
- wherein when in the raised position, each of the plurality of lifting devices are pivoted at a proximal end of the plurality of lifting devices,
- wherein each lifting device of the plurality of lifting devices includes a contact member provided at a distal end opposite the proximal end for engaging a receiving member of a platform when the vehicle is positioned under the platform,
- wherein when the clutch is in the coupled position, the second wheel rotates with the truck axle, and when the clutch is in the decoupled position, the second wheel is free to rotate relative to the truck axle.
