Abstract

A hybrid transmission for a motor vehicle is provided. The hybrid transmission includes a primary shaft, an electric motor power transmitting mechanism, an electric motor drive shaft, a combustion engine drive shaft, and a combustion engine power-transmitting mechanism. The electric motor drive shaft can be driven by an electric motor and is connected to the primary shaft in a power-transmitting manner via the electric motor power-transmitting mechanism. The combustion engine drive shaft is a crankshaft or is rotatably connected with a crankshaft, and is arranged, at least in sections, in the region between the primary shaft and the electric motor drive shaft. The combustion engine power-transmitting mechanism is arranged adjacent to the electric motor power-transmitting mechanism. A hybrid vehicle including such a hybrid transmission is also provided.

Claims18

Dependent claims

A hybrid transmission for a motor vehicle, comprising:

a primary shaft;
an electric power transmission mechanism;
an electric drive shaft which is drivable by an electric motor, and which is connected in a power-transmitting manner to the primary shaft via the electric power transmission mechanism;
an internal combustion engine drive shaft which is a crankshaft or is connected fixedly to a crankshaft so as to rotate therewith, the internal combustion engine drive shaft being arranged at least in sections in a region between the primary shaft and the electric drive shaft;
and
an internal combustion engine power transmission mechanism which is arranged adjacently with respect to the electric power transmission mechanism defining a plane,
wherein the electric power transmission mechanism is adapted to transmit power from the electric drive shaft to the primary shaft within the plane which is perpendicular to the primary shaft.
