Abstract

The present invention relates to the technical field of automobile transmission, in particular to a six-speed transmission, which includes a transmission casing and an input shaft, an output shaft, a planetary row set, and a torque transmission device installed inside the transmission casing. The first planetary row, the second planetary row, and the third planetary row are installed. The torque transmission device includes a first clutch, a second clutch, a third clutch, a first brake, a second brake, and a third brake. The first A brake, the second brake and the third brake are all fixedly connected to the transmission case. The six-speed transmission provided by the present invention is driven by a planetary gear train. The three planetary rows have a compact structure, and its power can be transmitted through several planetary gears. Arrangement use.

Description

technical field [0001] The invention relates to the technical field of automobile transmission, in particular to a six-speed transmission. Background technique [0002] Automatic transmissions have been widely used in modern automobiles. As one of the most complex assemblies in automobiles, for most models, the development of automatic transmissions with better performance has always been a hot spot pursued by the international scientific and technological circles. From traditional manual transmissions to The shift to automatic transmission technology is unstoppable. Therefore, the development of automatic transmissions with excellent performance has always been the focus of researchers. [0003] Automatic transmissions use planetary gear trains, clutches and brakes to compose and achieve multiple gear ratios. Generally speaking, the automatic transmission mechanism with greater transmission efficiency and transmission ratio range for each gear and stable transmission betw...
