Abstract
In one example, a hybrid drive unit comprises an electric motor, an axle differential for connection with a further motor, a first axle half shaft and a second axle half shaft connected to the axle differential, a first clutching device and a second clutching device. The electric motor is selectively drivingly engagable with the first axle half shaft via the first clutching device and with the second axle half shaft via the second clutching device.
Claims16
A hybrid drive unit, comprising:
- a first electric motor;
- an axle differential for connection with a second electric motor, an internal combustion engine, or a hydraulic motor;
- a first axle half shaft and a second axle half shaft connected to the axle differential;
- a first clutching device and a second clutching device;
- wherein the electric motor is selectively drivingly engagable with the first axle half shaft via the first clutching device and with the second axle half shaft via the second clutching device;
- wherein the first electric motor comprises a rotor coaxially aligned with or arranged in parallel to the first axle half shaft;
- and
- wherein the first axle half shaft reaches through the rotor of the first electric motor.
A method for a hybrid drive unit having a first electric motor, an axle differential for connection with a second electric motor, an internal combustion engine, or a hydraulic motor, a first axle half shaft and a second axle half shaft connected to the axle differential, and a first clutching device, a second clutching device, the method comprising:
- controlling the first clutching device and the second clutching device independently of one another, including
- selectively drivingly engaging the first axle half shaft via the first clutching device and with the second axle half shaft via the second clutching device;
- during a first mode of operation, opening the first clutching device and the second clutching device and driving the first axle half shaft and the second axle half shaft with the second electric motor, an internal combustion engine, or a hydraulic motor via the axle differential;
- and
- during a second mode of operation, closing or partially closing the first clutching device and the second clutching device and drivingly disengaging the first axle half shaft and the second axle half shaft with the second electric motor, the internal combustion engine, or the hydraulic motor via the axle differential.
