Abstract

A drive train device for a motor vehicle is disclosed. The drive train device has at least one component which is included for the purpose of transmitting a torque, and at least one cast-in element which is partially cast into the component, which is included for the purpose of transmitting the torque, where the component and the cast-in element are made of different materials. The drive train device has a sealing device which is included for the purpose of sealing a junction between the component and the cast-in element.

First claim

The invention claimed is:

1. A drive train device for a motor vehicle, comprising:
a first component for a purpose of transmitting a torque;
a cast-in element which is partially cast into the first component, wherein the cast-in element is for the purpose of transmitting the torque, wherein the first component and the cast-in element are made of different materials;
wherein the first component is indirectly connected, in a manner which transmits torque, to a second component which is for the purpose of transmitting the torque, via the cast-in element such that the torque can only be transmitted between the first component and the second component via the cast-in element; and
a sealing device, wherein the sealing device seals a junction between the first component and the cast-in element;
wherein the sealing device has a sealing element which is disposed between the first component and the cast-in element.

2. The drive train device according to claim 1 , wherein the second component together with the first component at least partially enclose an inner space and wherein the sealing device seals the junction and the inner space against each other.

3. The drive train device according to claim 1 , wherein the sealing device provides a sealing force due to an at least partially elastic deformation and/or due to adhesion to seal the junction.

4. The drive train device according to claim 1 , wherein the first component has a sealing element receptacle which at least partially receives the sealing element.

5. A drive train device for a motor vehicle, comprising:
a first component for a purpose of transmitting a torque;
a cast-in element which is partially cast into the first component, wherein the cast-in element is for the purpose of transmitting the torque, wherein the first component and the cast-in element are made of different materials;
wherein the first component is indirectly connected, in a manner which transmits torque, to a second component which is for the purpose of transmitting the torque, via the cast-in element such that the torque can only be transmitted between the first component and the second component via the cast-in element; and
a sealing device, wherein the sealing device seals a junction between the first component and the cast-in element;
wherein the sealing device has a sealing element which is disposed between the first component and the second component to provide a seal;
wherein the first component has a sealing element receptacle which at least partially receives the sealing element;
wherein the second component at least partially engages into the sealing element receptacle.

6. A drive train device for a motor vehicle, comprising:
a first component for a purpose of transmitting a torque;
a cast-in element which is partially cast into the first component, wherein the cast-in element is for the purpose of transmitting the torque, wherein the first component and the cast-in element are made of different materials;
wherein the first component is indirectly connected, in a manner which transmits torque, to a second component which is for the purpose of transmitting the torque, via the cast-in element such that the torque can only be transmitted between the first component and the second component via the cast-in element; and
a sealing device, wherein the sealing device seals a junction between the first component and the cast-in element;
wherein the sealing device has a sealing element which is disposed between the first component and the second component to provide a seal;
wherein the first component has a sealing element receptacle which at least partially receives the sealing element;
wherein the first component has a movement constraint for the sealing element wherein the movement constraint impedes a movement of the sealing element in the sealing element receptacle.

7. A drive train device for a motor vehicle, comprising:
a first component for a purpose of transmitting a torque;
a cast-in element which is partially cast into the first component, wherein the cast-in element is for the purpose of transmitting the torque, wherein the first component and the cast-in element are made of different materials;
wherein the first component is indirectly connected, in a manner which transmits torque, to a second component which is for the purpose of transmitting the torque, via the cast-in element such that the torque can only be transmitted between the first component and the second component via the cast-in element; and
a sealing device, wherein the sealing device seals a junction between the first component and the cast-in element;
wherein the sealing device has a sealing element which is disposed between the first component and the second component to provide a seal;
wherein the first component has a sealing element receptacle which at least partially receives the sealing element;
wherein the sealing element receptacle is a material void which is open toward the second component and has an annular shape in a form of a groove which is open in an axial direction;
wherein the sealing element receptacle is disposed radially inside the cast-in element with respect to an axis of rotation of the first component and the second component;
wherein the sealing element receptacle is bounded axially in a direction facing away from the second component and radially in a direction facing the axis of rotation by the first component;
wherein in a direction facing away from the axis of rotation, the sealing element receptacle is bounded radially by the cast-in element;
wherein, to form the sealing element receptacle, the first component has a projection which is disposed radially below the cast-in element and which extends axially from a surface of the first component which faces the second component in a direction of the second component, wherein the sealing element is supported on the projection and is disposed on the projection, and wherein the sealing element receptacle is formed by casting of the first component.
