Description
Technical field
This utility model relates to transmission technology field, in particular, relating to a kind of mixed connection formula twin countershaft transmission.
Background technology
Since variator is born, it has also become the important component part that automobile is indispensable, and type gets more and more, and the development of variator tends to variation.It is broadly divided into: manual transmission (MT), hydraulic automatic speed variator (AT), electric-controlled mechanical automatic speed transmission (AMT), buncher (DCT).
Current most of sedan is front-wheel drive mode, and matched variator is twin-shaft transmission, and including power shaft and output shaft, and this two axle is arranged in parallel, and power shaft is also the driven shaft of clutch, and output shaft is also the driving shaft of main reducing gear.As a example by five speed transmission: in order to realize gear change, power shaft is provided with five gear driving gears, corresponding output shaft is provided with five driven gears, by the engagement of different gear pairs, it is achieved the change of different gears.By foregoing description, the variator mated with front-wheel drive mode does not has jackshaft, when increasing gear, need to increase gear pair on power shaft and output shaft, to realize the increase of gear, but, the variator of front-wheel drive mode is mounted in the vehicle head part of vehicle, its installing space is less, and increasing gear on power shaft and output shaft needs to increase power shaft and the length of output shaft undoubtedly, which increases the difficulty of design.
