Background technique
Double disengaging type automatic transmission are one kind of automatic gearbox, not only inherit many excellent of manual transmission
Point also solves the existing cutting power shifting problem of electric control mechanical type automatic speed variator, the dynamic property and gear shifting characteristic of automobile
It is good, while oil consumption and discharge are also reduced, the economy of automobile might as well.The patent that notification number is CN 101737462A at present is public
A kind of double-clutch transmission mechanism of cloth, as shown in figure 3, three gear driving gears 10 in device on the first countershaft 7, second is secondary
Two gear driving gear 16 on axis 13 and two or three on jackshaft 1 driven gear 21 that reverses gear engage, and the driving gear 17 that reverses gear passes through
Reverse gear carrier gear 23 and two or three on jackshaft 1 on bridge shaft 24 driven gear 21 that reverses gear engage, and it is total to form five gears
Same meshing phenomena, the profile modifying parameters of five total grinding tooth wheels be difficult to ensure second gear, three gears, the NVH(Noise under each operating condition of reversing gear,
The english abbreviation of Vibration, Harshness, i.e. noise, vibration and sound vibration roughness), cause speed changer NVH performance poor, and
Noise, vibration and sound vibration roughness are a global questions for measuring automobile manufacture quality, and the NVH problem of vehicle is international vapour
One of the problem of major vehicle manufacturing enterprise of Che Yezhong and parts enterprises are paid close attention to.There is statistics to show, there are about 1/3 for vehicle
Failure problems are that have relationship with the NVH problem of vehicle, and each major company has nearly 20% R & D Cost consumption solving vehicle
In NVH problem.And four gear driving gears 14 will also directly be connected with the gear of differential mechanism simultaneously as output gear, and transmitting is dynamic
When power, in addition to four gears, a gear, second gear, three gears, five gears, the power to reverse gear are both needed to keep off driven gear 20 by the 45 of jackshaft
Four gear driving gears 14 are transmitted to, then are transmitted on the gear of differential mechanism by four gear driving gears 14, will lead to four gears in this way
The abrasion of the bearing support of driving gear 14 and the second countershaft 13 is accelerated, the bearing support of four gear driving gears 14 and the second countershaft 13
Reduced service life.The middle position of the second countershaft 13 is set because of reverse gear 17 simultaneously, since reverse gear 17 is the
Biggish torque is born in the middle position of two countershafts 13, and the bending deformation quantity that will cause the second countershaft 13 when reversing gear is big, serious shadow
Ring the power transmitting reversed gear.
