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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The hybrid transmission according to claim 1, wherein the internal combustion engine drive shaft crosses the plane. ### Claim 3 (depends on 2) The hybrid transmission according to claim 2, wherein the electric power transmission mechanism is a gearwheel drive, a first gearwheel is fastened on the electric drive shaft, a second gearwheel is fastened on the primary shaft, and a third gearwheel which is arranged between the first and second gearwheels is mounted rotatably on the internal combustion engine drive shaft. ### Claim 4 (depends on 3) The hybrid transmission according to claim 3, wherein the electric motor is arranged, with regard to the electric power transmission mechanism, on an opposite side to the internal combustion engine power transmission mechanism. ### Claim 5 (depends on 3) The hybrid transmission according to claim 3, further comprising: a secondary shaft which is arranged parallel to the primary shaft. ### Claim 6 (depends on 2) The hybrid transmission according to claim 2, wherein the electric power transmission mechanism is a belt drive. ### Claim 7 (depends on 6) The hybrid transmission according to claim 6, wherein the electric motor is arranged, with regard to the electric power transmission mechanism, on an opposite side to the internal combustion engine power transmission mechanism. ### Claim 8 (depends on 2) The hybrid transmission according to claim 2, wherein the internal combustion engine power transmission mechanism is a gearwheel drive which is adapted to transmit power within a plane which is parallel to the plane of the electric power transmission mechanism. ### Claim 9 (depends on 8) The hybrid transmission according to claim 8, wherein the internal combustion engine power transmission mechanism includes a clutch and a gearwheel drive. ### Claim 10 (depends on 9) The hybrid transmission according to claim 9, wherein the electric motor is arranged, with regard to the electric power transmission mechanism, on an opposite side to the internal combustion engine power transmission mechanism. ### Claim 11 (depends on 1) The hybrid transmission according to claim 1, wherein the electric power transmission mechanism is a belt drive. ### Claim 12 (depends on 1) The hybrid transmission according to claim 1, wherein the internal combustion engine power transmission mechanism includes a clutch and a gearwheel drive. ### Claim 13 (depends on 1) The hybrid transmission according to claim 1, wherein the electric motor is arranged, with regard to the electric power transmission mechanism, on an opposite side to the internal combustion engine power transmission mechanism. ### Claim 14 (depends on 1) The hybrid transmission according to claim 1, further comprising: a secondary shaft which is arranged parallel to the primary shaft. ### Claim 15 (depends on 1) A hybrid motor vehicle, comprising: a hybrid transmission according to claim 1. ### Claim 16 (depends on 15) The hybrid motor vehicle according to claim 15, wherein the hybrid motor vehicle is a hybrid motorcycle. ### Claim 17 (depends on 1) The hybrid transmission according to claim 1, wherein the electric motor is arranged, with regard to the electric power transmission mechanism, on a same side to an internal combustion engine. ### Claim 18 (depends on 1) The hybrid transmission according to claim 1, wherein the electric drive shaft is arranged, with regard to the electric power transmission mechanism, on a same side to the primary shaft.
