Description
Technical field
What the present invention relates to is a kind of transmission for vehicles, in particular a kind of Quick-shift transmission.
Background technique
Seven common at present fast dual clutch transmission structure are: two clutches connect outer hollow shaft and interior solid axle respectively.Wherein outer hollow shaft control 2,4,6, R shelves, interior solid axle control 1,3,5,7 grade.When speed changer operates, one group of gear is engaged, and during close to gearshift, the gear of next group gear section is by preliminary election, but clutch is still in separated state; When shifting gears, the gear in use is separated by a clutch, and another clutch engagement is simultaneously by the gear of pre-gear selecting section.And so-called gear shift is only utilized by power transmission hydraulic system to change among two groups of clutches.Dual clutch transmission structure is complicated, also higher to the requirement of manufacturing process, so cost is also higher; In the road conditions of complexity, speed changer can not judge the intention of driver normally, thus engages frequently and be separated preliminary election gear.And engage frequently and be separated gear, synchronizer minimizing in working life can be made, and produce a large amount of heats, strengthen the burden to sink.
Seven fast hands are from arranging gearbox: use four independently selector forks, two adjacent shifting gears are then controlled by different selector fork.Four independent shift forks control 1 gear and reverse gear respectively; 3 gear and 5 gear, 2 gear and 4 gear, 6 gear and 7 gear, that is, from 1 keep off up to 6 keep off, two adjacent gears all by two independently shift fork control respectively.When adjacent two gears will carry out gear switching, when the gear of selector fork and current gear departs from, another shift gear starts engagement, and the action of selector fork have activated electric clutch (cut off engine power or connect engine power) simultaneously, because three actions are almost synchronously carried out, whole process needed time is therefore made greatly to shorten.But in shift process, easily produce power interruption, and to the precision of Servocontrol device and rate request higher.
Summary of the invention
