BACKGROUND OF THE INVENTION

1. Field of the Invention

The disclosure is directed to a hybrid module comprising an internal combustion engine and an electric machine, wherein a disconnect clutch, also known as K0, is provided between the internal combustion engine and the electric machine.

2. Description of Related Art

Hybrid modules with a K0are known from the prior art. The K0requires extensive additional installation space, which has an adverse effect on vehicle design. Further, the constructions put forth as solutions are relatively complex and lead to extensive manufacturing expenditure.

SUMMARY OF THE INVENTION

It is the object of one aspect of the invention to provide a hybrid module that requires less installation space, is less complex to construct and/or is more easily producible compared with the prior art.

This object is met through the embodiment forms described in the following.

According to one aspect of the invention, an oil guide of a hybrid module for a vehicle arranged in a drivetrain between a drive unit, particularly an internal combustion engine, and an output, wherein an electric machine is provided, and a rotor of the electric machine is connected to the output, wherein a clutch is provided between the drive unit and the electric machine, is characterized in that the clutch has oil conducting elements in order to supply the electric machine with cooling oil.

Embodiment forms of an oil guide are characterized in that the clutch is formed as a cone clutch, in that the cone clutch has at least one outer friction ring (ARR) and one intermediate friction ring (ZRR), in that the outer friction ring (ARR) is connected to the rotor, and in that the cone of the cone clutch in the open state forms an oil guide to an axial end of the rotor.

Advantageous embodiment forms of an oil guide are characterized in that, at the outer friction ring (ARR), bores are provided at the tapered side of the cone in order to conduct cooling oil to the other axial end of the rotor.

Oil guides according to embodiment forms are characterized in that the outer friction ring (ARR) is formed integral with a rotor carrier of the rotor of the electric machine.

Embodiment forms of an oil guide are characterized in that a retaining ring for axial positioning of the clutch protrudes in radial direction relative to the rotor in order to serve as retaining element for cooling oil.

Embodiment forms of an oil guide are characterized in that a return spring of the clutch is formed as cup spring, and in that orifices are provided at the inner diameter of the cup spring for controlling oil.

Oil guides according to embodiment forms are characterized in that an oil baffle is provided at the clutch.

Advantageous embodiment forms of an oil guide are characterized in that the oil baffle is mounted in or welded to the inner friction ring (IRR) or intermediate friction ring (ZRR).

A further aspect of the invention is a hybrid module with an oil guide according to one of the described embodiment forms.

Embodiment forms of a hybrid module are characterized in that a torsional damper is arranged between the drive unit and the electric machine upstream and/or downstream of the clutch.

Hybrid modules according to embodiment forms are characterized in that the cone clutch is operatively connected on the driven side to a torque converter.

Embodiment forms of a hybrid module are characterized in that the cone clutch has only one friction surface.

Hybrid modules according to embodiment forms are characterized in that the cone clutch has at least one outer friction ring (ARR) and one intermediate friction ring (ZRR), and in that outer friction ring (ARR) is connected to the rotor.

Further embodiment forms of a hybrid module are characterized in that the outer friction ring (ARR) is formed integral with a rotor carrier of the rotor.

Hybrid modules according to preferred embodiment forms are characterized in that a connection plate is provided on the driving side, and the intermediate friction ring (ZRR) is connected to the connection plate by positive engagement in circumferential direction and is moveable axially with respect to the connection plate.

Embodiment forms of a hybrid module are characterized in that the cone clutch has an inner friction ring (IRR), and in that the outer friction ring (ARR) and the inner friction ring (IRR) are arranged so as to be fixed with respect to rotation relative to one another.

Hybrid modules according to embodiment forms are characterized in that the intermediate friction ring (ZRR) is formed in a segmented manner.

Embodiment forms of a hybrid module are characterized in that the cone clutch is formed as a normally open type.

Hybrid modules in embodiment forms are characterized in that the cone clutch is formed with at least one inserted friction lining that is not fixedly connected to another component part of the cone clutch.

Embodiment forms of a hybrid module are characterized in that the cone clutch can be actuated via a piston, and in that the piston is formed integral with the inner friction ring (IRR).

Embodiment forms of a hybrid module are characterized in that the cone clutch in a normally open type cone clutch tapers in direction of piston actuation, and in that the cone in a normally closed type cone clutch tapers opposite the direction of piston actuation.

Hybrid modules according to embodiment forms are characterized in that an oil baffle is provided at the cone clutch.

Embodiment forms of a hybrid module are characterized in that, for directing oil, a portion of the oil flow is guided through the open cone clutch, and this portion of the oil flow is interrupted when the cone clutch is actuated.
