Abstract
A transverse vehicle drive assembly, wherein the transverse vehicle drive assembly comprises a first power source and an automatic transmission (10), a first intermediate shaft (31) is provided parallel to a first input shaft (21) of the automatic transmission (10), a second intermediate shaft (32) is provided coaxial with the first input shaft (21), a third intermediate shaft (33) is provided coaxial with the first intermediate shaft (31), a first clutch (41) is provided between the first intermediate shaft (31) and the third intermediate shaft (33), and a second clutch (42) is provided between the first input shaft (21) and the second intermediate shaft (32). A first gear (11) on the first input shaft (21) and a second gear (12) on the first intermediate shaft (31) are in engaged transmission; and a third gear (13) on the second intermediate shaft (32) and a fourth gear (14) on the third intermediate shaft (33) are in engaged transmission, and the fourth gear (14) on the third intermediate shaft (33) is simultaneously in engaged transmission with a fifth gear (15) on a differential (50). The drive assembly can realize transmission of two speed ratios, and the transmission modes are flexible. The longitudinal dimension and the lateral dimension of the drive assembly are reduced, to be adapted for vehicles of a compact structure. Because a small quantity of gears are used, the transmission structure is simplified.
