Abstract

A multi-speed automatic transmission, comprising a first shaft system WS1, a second shaft system WS2, a first fixed shaft gear set TG69, a second fixed shaft gear group TG56, a third fixed shaft gear set TG17, a first planetary gear set PG1, the second planetary gear set PG2, the third planetary gear set PG3 and 6 shift elements, namely the first brake B1, the second brake B2, the first clutch C1, the second clutch C2, the third clutch C3, and the fourth clutch C4: Power is input from the first shaft system WS1, output to the differential Diff. through the second shaft system WS2, and then transmitted to the wheels on both sides through the output terminals on both sides of the differential. The first shaft system and the second shaft system are arranged in parallel, which is especially suitable for front-drive vehicles; the compact structure makes the vehicle shift response faster, and the stronger power can make the vehicle have better driving performance and better fuel consumption economy.

Description

technical field

[0001] The invention provides a multi-gear automatic transmission, which relates to a multi-gear automatic transmission capable of power shifting. As a power transmission device, it is especially suitable for front-drive type passenger vehicles. The invention belongs to the technical field of automobile transmission system. Background technique

[0002] In order to reduce the fuel consumption of vehicles and improve their drivability, the number of gears in automatic transmissions of passenger cars is increasing. In the field of passenger vehicles, automatic transmission (AT) arrangements are mainly divided into two types: longitudinal arrangement (applied to front-rear drive vehicles) and transverse arrangement (applied to front-front drive vehicles). The mechanical components of the longitudinal automatic transmission are arranged coaxially. The mechanical parts of the transverse automatic transmission are arranged in parallel shafts, and are connected wi...
