Title:
SEVEN-GEAR DUAL CLUTCH TRANSMISSION AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/184145
Kind Code:
A1
Abstract:
A seven-gear dual clutch transmission and a vehicle. The seven-gear dual clutch transmission comprises: an external input shaft (1), an internal input shaft (14), a first output shaft (15), a second output shaft (9), and a drive gear synchronization device. A fourth/sixth-gear driving gear (26) and a second-gear driving gear (25) are sequentially fixed on the external input shaft (1) in a direction distant from a power source (27). A first-gear driving gear (11), a third-gear driving gear (12), and a fifth/seventh-gear driving gear (13) are sequentially fixed on the internal input shaft (14) in a direction distant from the power source (27). A fourth-gear driven gear (23), a second-gear driven gear (19), a first-gear driven gear (18), and a fifth-gear driven gear (16) are sequentially provided on the first output shaft (15) in a direction distant from the power source (27). A sixth-gear driven gear (3), a reverse gear (5), a reverse synchronizer (6), a third-gear driven gear (7), and a seventh-gear driven gear (10) are sequentially provided on the second output shaft (9) in a direction distant from the power source (27). The seven-gear dual clutch transmission removes a reverse gear shaft, and thus the structure is more compact, and the reverse transmission line is simpler, thereby greatly improving the NVH performance.
