A multi-position clutch allows selectively coupling at least two of at least three rotatable shafts is described herein. The clutch comprises at least three cooperation elements respectively associated to one of the at least three rotatable shafts for selective engagement therebetween; the at least three cooperation elements are mounted to the at least three rotatable shafts so as to be sequentially positioned for selective coupling of at least two adjacent cooperation elements. An actuating mechanism is provided for selectively coupling at least two adjacent cooperation elements from the at least three cooperation elements.

Multi-position clutch

A first aspect of the present invention is concerned with a series hybrid drive train for a vehicle comprising a traction motor, an electric generator, a three-position clutch () and a controller. The three-position clutch allows the generator to be connected to an internal combustion engine () of the vehicle, to the traction motor or to remain freewheeling. In a second aspect of the present invention, a four-position clutch is used to further allow the internal combustion engine to be connected directly to the wheels to thereby yield a series/parallel drive train. A third aspect of the present invention is concerned with a method of operating such a hybrid drive train.

Hybrid drive train for vehicle

A cooling assembly including a generally cylindrical body to be inserted inside the generally cylindrical internal stator of an electric machine is described herein. The body includes a cylindrical external contact surface configured and sized to contact the internal surface of the stator. The bottom surface of the body is machine with a channel that is partially closed by a cover to yield a peripheral fluid passage inside the body. An inlet and an outlet aperture are provided.

Cooling assembly for electric machine

A cooling device for an internal stator of an electric machine. The stator includes a substantially cylindrical cavity having a substantially cylindrical internal surface. The cooling device includes a body defining an external substantially cylindrical contact surface. The cooling device further includes a biasing element connected to the body. The biasing element is so configured and sized as to bias the contact surface of the body against the internal surface of the rotor when the cooling device is positioned inside the cavity.
