Abstract

The invention discloses a multi-gear automatic transmission and a vehicle with the same. The multi-gear automatic transmission comprises an input shaft, an output shaft, four planetary gear sets, fiveclutches and three brakes. The four planetary gear sets include a first planetary gear set, a second planetary gear set, a third planetary gear set, and a fourth planetary gear set. Each planetary gear set includes a sun gear, a planet carrier, and a ring gear, the five clutches comprise a first clutch, a second clutch, a third clutch, a fourth clutch, and a fifth clutch, wherein the first clutch, the second clutch, and the third clutch are connected with the input shaft, and the fourth clutch and the fifth clutch are connected with a first planet carrier. The three brakes include a first brake, a second brake, and a third brake. According to the multi-gear automatic transmission, not only is the shaft sleeve connection form is simple, the occupied space is small, and the arrangement is convenient, but also the multiple clutches are used for planetary gear set connection, the speed ratio range is wide, and the number of gears is large.

Description

technical field [0001] The invention belongs to the field of transmissions, in particular to a multi-speed automatic transmission and a vehicle with it. Background technique [0002] The existing automatic transmission can realize 8 forward gears and 1 reverse gear by using four planetary gear sets, and the gears are less. Moreover, the number of layers of the shaft sleeve is large, and there are two sets of clutches for the connection of the planetary gear sets, and the range of the speed ratio is narrow. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a multi-speed automatic transmission. The multi-speed automatic transmission not only has a simple shaft sleeve connection form, occupies a small space, and is convenient for arrangement, but also uses a plurality of clutches for the connection of the planetary gear sets. The speed ratio rang...
