HORIZONTAL DRIVE ASSEMBLY OF DUAL POWER SOURCE VEHICLE

A vehicle drive assembly with transverse dual-power-source, comprising two power sources and an automatic transmission (). The automatic transmission () is provided with a first input shaft () and a second input shaft (), and the two power sources are respectively connected to the two input shafts (); a first intermediate shaft (), a second intermediate shaft () and a second input shaft () are provided coaxial with the first input shaft (); the third intermediate shaft () is provided parallel to the first input shaft (), and a fourth intermediate shaft () is provided coaxial with the third intermediate shaft (); a first gear () on the first intermediate shaft () and a second gear () on the third intermediate shaft () are in engaged transmission; a third gear () on the second intermediate shaft () and a fourth gear () on the fourth intermediate shaft () are in engaged transmission; and a differential () is provided with a fifth gear, the third gear () and the fourth gear () are in engaged transmission, and the fourth gear () is simultaneously in engaged transmission with a fifth gear (). The drive assembly, in an aspect, has a reduced longitudinal dimension, to be adapted for vehicles of a compact structure, and, in another aspect, uses a small quantity of gears, which simplifies the transmission structure.
