Abstract
Systems are disclosed for a master drive unit including a traction motor, a steering motor, and a planetary steering system, wherein the traction motor, steering motor, and planetary steering system are mounted inline. The planetary steering system is a speed reduction system for reducing an output speed from the steering motor, whilst at the same time increasing output torque.
Claims20
A master drive unit, comprising:
- a traction motor;
- a steering motor;
- and
- a planetary steering system, wherein the traction motor, the steering motor, and the planetary steering system are mounted inline.
1 more element
A master drive unit, comprising:
- a traction motor adapted to rotate a wheel about a lateral axis via gears and shafts;
- a steering motor adapted to rotate the wheel about a vertical axis perpendicular to the lateral axis via a planetary steering system vertically stacked with the traction motor and the steering motor in series along the vertical axis, wherein the planetary steering system rotationally couples the steering motor with a gearbox housing enclosing the gears and the shafts driven by the traction motor.
A vehicle, comprising:
- one or more master drive units each positioned vertically above a wheel and including:
- a traction motor adapted to rotate the wheel about a lateral axis;
- a steering motor adapted to rotate the wheel about a vertical axis;
- and
- a planetary steering system for speed reduction of the steering motor, wherein the traction motor, the steering motor, and at least some components of the planetary steering system are coaxially centered about the vertical axis;
- and
- a controller adapted to send a signal to drive to the traction motor to rotate the wheel about the lateral axis and to the steering motor to rotate the wheel about the vertical axis.
