Abstract

A vehicle drive including a transmission-engine arrangement with two drive units that are operatable independently of each other and include drive shafts arranged in the longitudinal direction of the vehicle, and with two transmission units, a respective one of the drive units forming a partial drive train with one of the transmission units, and a respective clutch device being arranged between the drive units and the transmission units within the partial drive trains. The clutch devices of the two partial drive trains are arranged to be offset relative to each other in the longitudinal direction of the vehicle to be capable of being arranged with an overlap as viewed in the transversal direction of the vehicle.

Claims (6)

1. A vehicle drive, including a transmission-engine arrangement with two drive units that are operatable independently of each other and include drive shafts arranged in the longitudinal direction of the vehicle, and with two transmission units, a respective one of the drive units forming a partial drive train with one of the transmission units, and a respective clutch device being arranged between the drive units and the transmission units within the partial drive trains, wherein the clutch devices of the two partial drive trains are arranged to be offset relative to each other in the longitudinal direction of the vehicle to be capable of being arranged with an overlap as viewed in the transversal direction of the vehicle.

2. A vehicle drive as set forth in claim 1 , including a transmission-engine arrangement with two drive units that are operatable independently of each other and include drive shafts arranged in the driving direction of the vehicle, and with two transmission units, a respective one of the drive units forming a partial drive train with one of the transmission units, and a respective clutch device being arranged between the drive units and the transmission units within the two partial drive trains, wherein the drive units are designed as combustion engines that are subdivided into two or more autonomous partial combustion engines by providing respective crankshafts that are subdividable into two or more crankshaft portions via clutch devices integrated into the respective crankshafts, the crankshaft portions being activatable depending on the desired torque.

3. The vehicle drive as set forth in claim 1 , wherein torques introduced into the partial drive trains are transmitted to driven wheels of the vehicle via a differential, a differential shaft being provided, as viewed in the longitudinal direction of the vehicle, between the drive units and the clutch devices arranged between a combustion engines and the transmission units.

4. The vehicle drive as set forth in claim 3 , wherein the partial drive trains are combined via a common output shaft that transmits a total torque to the differential connected to the driven wheels of the vehicle.

5. The vehicle drive as set forth in claim 4 , wherein the common output shaft is arranged outside the transmission input shafts and adjacent to the differential as viewed in the transversal direction of the vehicle.

6. The vehicle drive as set forth in claim 4 , wherein the common output shaft is arranged between the transmission input shafts as viewed in the transversal direction of the vehicle, and wherein the differential is arranged outside the transmission input shafts as viewed in the transversal direction of the vehicle.
