Abstract

A motorized vehicle has a plurality of left wheels and right wheels. The vehicle includes a first motor adapted for powering at least two of the plurality of left wheels and a second motor adapted for powering at least two of the plurality of right wheels. The vehicle also includes a first power transferring device for transferring power from the first motor to a left wheel, a second power transferring device for transferring power from the second motor to a right wheel, a third power transferring device for transferring power from the first left wheel to a second left wheel, and a fourth power transferring device for transferring power from the first right wheel to a second right wheel. The vehicle also includes a first braking mechanism for the first of the left wheels and a second braking mechanism for the second of the left wheels.

First claim

What is claimed is:

1. A motorized vehicle, the vehicle having a plurality of left wheels and a plurality of right wheels, the vehicle comprising: a first motor adapted for powering at least two of the plurality of left wheels; a second motor adapted for powering at least two of the plurality of right wheels; a first power transferring device for transferring power from the first motor to a first of the plurality of left wheels; a second power transferring device for transferring power from the second motor to a first of the plurality of right wheels; a third power transferring device for transferring power from the first of the plurality of left wheels to a second of the plurality of left wheels; a fourth power transferring device for transferring power from the first of the plurality of right wheels to a second of the plurality of right wheels; a first braking mechanism operably associated with the first of the plurality of left wheels; and a second braking mechanism operably associated with the second of the plurality of left wheels, further comprising a first speed reduction device positioned between the first power transferring device and the first of the plurality of left wheels; and wherein the first speed reduction device includes a housing, an adapter mounted to the housing, and a crown gear mounted to the adapter.

2. A motorized vehicle, the vehicle having a plurality of left wheels and a plurality of right wheels, the vehicle comprising: a first motor adapted for powering at least two of the plurality of left wheels; a second motor adapted for powering at least two of the plurality of right wheels; a first power transferring device for transferring power from the first motor to a first of the plurality of left wheels; a second power transferring device for transferring power from the second motor to a first of the plurality of right wheels; a third power transferring device for transferring power from the first of the plurality of left wheels to a second of the plurality of left wheels; a fourth power transferring device for transferring power from the first of the plurality of right wheels to a second of the plurality of right wheels; a first braking mechanism operably associated with the first of the plurality of left wheels; and a second braking mechanism operably associated with the second of the plurality of left wheels, further comprising a first speed reduction device positioned between the first power transferring device and the first of the plurality of left wheels; further comprising a second speed reduction device positioned between the first speed reduction device and the first of the plurality of left wheels.

3. The motorized vehicle of claim 1 , wherein the first braking mechanism is positioned between the first speed reduction device and the second speed reduction device.

4. The motorized vehicle of claim 1 , wherein the first braking mechanism is positioned between the second speed reduction device and the first of the plurality of left wheels.

5. The motorized vehicle of claim 1 , further comprising a kingpin operably connected to at least one of the first speed reduction device and second speed reduction device, at least one the first speed reduction device and second speed reduction device defining a cavity for receiving at least a portion of the kingpin, the cavity defining a chamber for containing a fluid for assisting in moving the kingpin from a locked position to an unlocked position.

6. A motorized vehicle, the vehicle having a plurality of left wheels and a plurality of right wheels, the vehicle comprising: a first motor adapted for powering at least two of the plurality of left wheels; a second motor adapted for powering at least two of the plurality of right wheels; a first power transferring device for transferring power from the first motor to a first of the plurality of left wheels; a second power transferring device for transferring power from the second motor to a first of the plurality of right wheels; a third power transferring device for transferring power from the first of the plurality of left wheels to a second of the plurality of left wheels; a fourth power transferring device for transferring power from the first of the plurality of right wheels to a second of the plurality of right wheels; a first braking mechanism operably associated with the first of the plurality of left wheels; and a second braking mechanism operably associated with the second of the plurality of left wheels, further comprising: a first speed reduction device operably associated with a first of the plurality of left wheels; a second speed reduction device positioned between the first speed reduction device and the first of the plurality of left wheels; a first sump operably associated with the first speed reduction device; and a second sump operably associated with the second speed reduction device.
