Title:
NINE-GEAR AUTOMATIC TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2020/029547
Kind Code:
A1
Abstract:
A nine-gear automatic transmission, comprising an input member (1), an output member (2), a transmission housing (23), a first planetary row, a second planetary row, a third planetary row, a first clutch (6), a second clutch (7), a third clutch (8), a fourth clutch (9), a first brake (3), a second brake (4), and a third brake (5). By means of a reasonable combination and arrangement of the four clutches and the three brakes, said nine-gear automatic transmission enables the distribution of the clutches and brakes to be further concentrated, so that the clutches and brakes can achieve a sufficient nested arrangement, thereby making the arrangement of the clutches and brakes highly integrated, further compressing the axial space of the entire planetary gear mechanism with the greatest possibility, making the entire planetary gear mechanism more compact.
