Abstract

The invention relates to a power transmission mechanism for a double-clutch automatic transmission for an automobile. The power transmission mechanism comprises a power input shaft, an odd shift clutch input shaft, a first auxiliary shaft, a second auxiliary shaft, a middle shaft, a reverse gear idler shaft, an odd shift clutch, an even shift clutch, and a differential; the left end of the power input shaft is provided with a sun gear, a planetary gear, an internal gear ring, and a fixed planet carrier; an internal gear ring external gear is fixed outside the internal gear ring; the second auxiliary shaft is provided with an even shift driving gear, a reverse gear driving gear and an even shift synchronizer; the middle shaft is provided with a driven gear and first and second reverse gear driven gears; and the reverse gear idler shaft is provided with first and second reverse gear idler gears. The transmission mechanism is simple and is high in integrated level, and manufacturing cost of the double-clutch automatic transmission is reduced to certain extent.

Description

technical field [0001] The invention relates to a power transmission mechanism of an automobile transmission, in particular to a power transmission mechanism of a dual-clutch automatic transmission. Background technique [0002] There are four main types of automotive automatic transmissions: hydromechanical automatic transmission (AT), electromechanical automatic transmission (AMT), mechanical continuously variable automatic transmission (CVT) and dual clutch automatic transmission (DCT). Among them, the dual-clutch automatic transmission (DCT) not only inherits many advantages of AMT and manual transmissions, such as simple structure, compact installation space, light weight, high transmission efficiency, and low manufacturing cost, but also integrates the advantages of AT uninterrupted power and rapid and smooth shifting. It is a transmission with excellent performance. [0003] The power transmission of dual-clutch automatic transmission (DCT) has two routes, one is the...
