Abstract
A power machine can include a power machine frame, an electric power source supported by the power machine frame, an electric motor powered by the electric power source, and a hydrostatic transmission powered by the electric motor. The electric motor can power the hydrostatic transmission via a power transmission assembly that transfers power from the electric motor to the hydrostatic transmission at a reduced rotational speed.
Claims20
A power machine comprising:
- a power machine frame;
- an electric power source supported by the power machine frame;
- an electric motor powered by the electric power source;
- a hydrostatic transmission powered by the electric motor;
- and
- a power transmission assembly configured to transfer power from the electric motor to the hydrostatic transmission at a reduced rotational speed relative to a rotational speed of the electric motor, so that the electric motor powers the hydrostatic transmission at the reduced rotational speed via the power transmission assembly.
3 more elements
A drive system for a power machine, the drive system comprising:
- an electric motor configured to be powered by an electric power source of the power machine;
- a hydrostatic transmission including a hydrostatic drive pump configured to power travel of the power machine over terrain;
- and
- a power transmission assembly operatively coupling the electric motor to the hydrostatic transmission to transmit power from the electric motor to the hydrostatic drive pump at a reduced rotational speed relative to a rotational speed of the electric motor.
1 more element
A tractor comprising:
- a tractor frame;
- an electric power source supported by the tractor frame;
- an electric motor supported by the tractor frame and configured to be powered by the electric power source;
- a hydrostatic transmission supported by the tractor frame;
- tractive elements configured to be powered by the hydrostatic transmission to convey the tractor over terrain;
- and
- a power transmission assembly supported by the tractor frame and configured to transfer power from the electric motor to the hydrostatic transmission to power the hydrostatic transmission with a smaller rotational speed at the hydrostatic transmission than provided by the electric motor.
