Description
Technical field
The present invention relates to gearbox technical field, be specifically related to a kind of Twin channel gearshift transmission separated type gearbox and controlling method thereof.
Background technique
Existing gearbox mostly adopts the different gear train of many group rotating ratios to form multiple gear, is in operation and selects the different gear of conversion according to actual needs, realize different gear ratio.Although this type of gearbox structure is simple, also have the following disadvantages:
One, because the gear rotational speed difference on each gear is very large, for avoiding occurring beating tooth phenomenon during gearshift, synchronizer need be installed additional on each gear, this adds increased volume and cost.
Two, need first stepping on clutch (although automatic catch need not artificial stepping on clutch when shifting gears, but in fact transmission internal still needs fluid torque converter that power and the separated of gearbox are converted gear) power is disconnected after could control gearbox and shift gears, this had both increased an act of operation, can make again automobile step on clutch to gearshift terminate after this following period of time of loosening the clutch cause potential safety hazard because temporarily losing driving force.
Three, during gearshift, there is the problem that pause and transition in rhythm or melody sense is serious.
Summary of the invention
The present invention is the problems referred to above solving prior art existence, proposes a kind of Twin channel gearshift transmission separated type gearbox and controlling method thereof.
