A hybrid drive () for a vehicle has an internal combustion engine (), an electric machine () and a double clutch transmission () with a hollow first input shaft () and a second input shaft () that penetrates the first input shaft (). A hollow transmission shaft () is parallel to the input shafts (), and a drive torque can be applied to the first or second input shafts () via the internal combustion engine () and/or the electric machine () via the double clutch () of the double clutch transmission (). The electric machine () is outside the double clutch transmission (), and an output shaft () of the electric machine () penetrates the hollow transmission shaft (). As a result, a compact configuration is ensured.

Hybrid drive for a vehicle

A cover and housing having a mounting arrangement, especially for a selector lever housing. According to the invention, the cover is fastened by means of two bearing points to provide a method of fastening a cover that can be mounted simply without adjustment and provides an exact fit for the cover. The first bearing point is made cylindrical and the axis of this cylinder runs parallel to a mounting direction or placement direction of the cover. The second bearing point is made wedge-shaped and the wedge axis lies in a plane that is perpendicular to the mounting direction or placement direction and is aligned so that it is not parallel to a tangent at the first cylindrical bearing point.

Mount for a cover

A reinforced fastening point for a plastics-material casing. In order to provide a reinforcement for a fastening point which is simple to assemble and which is held automatically in the opening in the casing without further fasteners, a cylindrical opening is provided at the fastening point on the casing. The reinforcement part corresponding thereto is constructed as a frustum in that region which in the assembled state comes to rest in the region of the cylindrical opening. The smaller external diameter of this frustum is smaller than or equal to the internal diameter of the cylindrical opening. The larger external diameter of the frustum, on the other hand, has an excess dimension with respect to the internal diameter of the cylindrical opening. In this case, the excess dimension is selected to be such that it can be neutralized by resilient deformation of the reinforcement part.
