Problems solved by technology

The present invention combines the advantages of DCT and CVT, discards their respective defects, and introduces a new type of automobile compound transmission double clutch transmission (Hybrid Double Clutch Transmission, hereinafter referred to as HDCT), which adopts gears with variable speed and variable pulley radius. The form of combining the continuously variable transmission with the new type is very suitable for the automatic transmission of cars. At present, no similar reports have been seen in this technical scheme at home and abroad.

Abstract

The invention relates to a car complex transmission double-clutch transmission which comprises a powder separation and coupling device, a stepless speed changing unit, a double-shaft transmission mechanism, part connecting gears and a gear selecting and shifting actuating mechanism, wherein the powder separation and coupling device comprises wet-type double clutches, and the stepless speed changing unit is a belt-type stepless speed changing unit capable of changing the radius of a belt wheel and comprises a driving belt wheel and a driven belt wheel; either belt wheel comprises a movable disc at one side and a fixed disc at the other side, and the movable disc can axially move; a hydraulic actuating mechanism pushes the movable disc to axially move so as to continuously change the working radius of the belt wheel and continuously change the transmission ratio of the belt-type stepless speed changing unit; the double-shaft transmission mechanism is formed by sleeving a hollow transmission shaft on a central transmission shaft to form two transmission shafts, respectively arranges gears of the transmission on the two transmission shafts connected with the two clutches according to odd numbers and even numbers and finishes the gear-shifting process by alternately shifting the two clutches to realize power gear shifting.

Description

Technical field [0001] The present invention is a dual-clutch transmission with composite transmission for automobiles, which adopts a combination of stepped gear shifting and belt-type stepless shifting with variable pulley radius. It belongs to the technical field of vehicle automatic shifting and can be used for front-engine and front-wheel drive. Or in a rear-wheel drive car, it can also be applied to other occasions where power needs to be transmitted in a variable speed mode. Background technique [0002] The traditional Double Clutch Transmission (hereinafter referred to as DCT) essentially combines two gear transmission gearboxes to make a stepped gear transmission. It uses two clutches to control odd-numbered gears and even-numbered gears respectively, and realizes the transmission of traction force in different gears through the pre-engagement of gears and the separation and engagement of two clutches. [0003] Although DCT solves the comfort problem of shifting, becaus...
