Abstract

The invention discloses a rear drive power assembly device and a vehicle. The rear drive power assembly device comprises a transverse engine and a longitudinal transmission, wherein the transmission comprises a first clutch, a second clutch, an inner input shaft, an outer input shaft, a first intermediate shaft, a second intermediate shaft and an output shaft; the engine is connected with the first clutch, a first input bevel gear pair and the inner input shaft in sequence, and is also connected with the second clutch, a second input bevel gear pair and the outer input shaft in sequence; driving gears of a forward gear pair are distributed on the inner input shaft and the outer input shaft, and driven gears are distributed on the first intermediate shaft and the second intermediate shaft; the driven gears are connected with the first intermediate shaft or the second intermediate shaft through corresponding synchronizers; and the first intermediate shaft and the second intermediate shaft output power to the output shaft through a first intermediate gear pair and a second intermediate gear pair respectively. An existing transverse engine can be reserved to the maximum extent, and the platformization and modularization design of a power assembly device, especially the engine, is achieved as much as possible; and the longitudinal transmission can be designed on the basis of an existing transverse transmission, the development period is shortened, and the development cost is reduced.

Description

technical field [0001] The invention belongs to the field of vehicles, in particular to a rear drive power assembly device and a vehicle. Background technique [0002] Currently, rear-wheel-drive vehicles on the market mostly use a longitudinally-mounted engine matched with a longitudinally-mounted transmission. For the planning of front-wheel drive and rear-wheel drive vehicles, it is necessary to develop engines and transmissions for each driving mode separately, and the generalization is low. , it is difficult to realize a platform-based and modular design among vehicles with different driving modes; in addition, the matching of the longitudinal engine and the longitudinal transmission to realize the rear drive of the vehicle is limited by the height of the floor, the power and economy of the powertrain device Difficult to improve sex. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rear drive power assembl...
