A hybrid powertrain for a vehicle includes an internal combustion engine having a crank shaft rotatable about a geometric axis, an electric machine and a transmission having an input shaft rotatable about the geometric axis, and a clutch by which clutch the internal combustion engine and the transmission are selectively connectable to each other. A rotor of the electric machine is arranged on the crank shaft for rotating together with the crank shaft about the geometric axis, and the clutch is a dog clutch arranged for connecting and disconnecting the crank shaft of the internal combustion engine and the input shaft of the transmission to and from each other.

Hybrid powertrain for a vehicle

A dual clutch for a transmission with a first transmission input shaft and a second transmission input shaft that is positioned in coaxial relation to the first transmission input shaft. The dual clutch comprises a clutch portion comprising a hollow cylinder portion for transmitting torque, wherein the hollow cylinder portion is provided in a radial position between a clutch axle and a clutch hub, is rotatable in relation to the clutch axle and the clutch hub, and comprises at least one opening allowing oil to be fed from the clutch axle to the clutch hub. This design allows supply of hydraulic oil, sufficient cooling oil, and at the same time flexibility in attaching auxiliary engines such as an electromotor to the dual clutch.

Dual wet clutch with an electric machine

A change-speed gearbox, in particular for motor vehicles such as hybrid passenger cars and small trucks, comprising input and output shafts, clutches, and gear wheel pairs with fixed and loose wheels. The gearbox provides at least one forward gear by means of the gear wheel pairs, has a gear box unit for a second forward gear, and has in addition an auxiliary drive.
