Background technology
Existing automotive transmission includes mechanical transmission, automatic transmission, auto-manual transmission and buncher,
Cvt (continuously variable transmission) variator has become current development of automobile variator faster.
Cart-wheel stepless speed variator can be by the effective diameter size of the master and slave Moving plate position of change roller contact in certain numerical value
In the range of continuous change gear ratio, there is compact conformation, reliable operation, stable drive, the low advantage of noise.But due to roller type
The gear ratio excursion of buncher is little, not also being applied on automobile.
Content of the invention
In order to overcome the shortcomings of existing variator, it is an object of the invention to provide a kind of automotive compounded variator of roller type,
It has the advantages that cart-wheel stepless speed variator and mechanical transmission, and the stepless change of roller type realized by automobile when 0 ~ 60km/h travels
Speed transmission, when automobile is automatically converted to low speed or high speed machine gear drive when more than 60km/h travels, thus overcome rolling
Wheel-ing stepless transmission and the deficiency of mechanical transmission, improve efficiency, reduce discharge.
The present invention can be realized by following measures: the roller type being formed in driving disc spacing pressing, roller, clutch plate and planetary gear set
A grade speed change gear is had additional on the basis of infinitely variable speed transmission.When 0 ~ 60km/h travels, roller type infinitely variable speeds pass automobile
Dynamic device work, roller is pressed to and drives clutch plate rotation, low-grade step speed change clutch and high-grade step speed change by driving disc spacing pressing
Clutch separation, the gear of output end through input shaft, driving disc spacing pressing, roller, clutch plate and planetary gear set for the power slows down and exports, then warp
Low-speed gear and jackshaft drive main reducing gear driven gear；By changing the contact position of four rolling and driving disc spacing pressing, clutch plate
The transmission speed ratio to change master and slave Moving plate for the effective diameter size put, thus realize roller type infinitely variable speeds；When automobile exceedes
During 60km/h, step speed change transmission operation, low-grade step speed change clutch and high-grade step speed change clutch joint, power
Through input shaft, low-grade step speed change clutch or high-grade step speed change clutch, low-speed gear, there is jackshaft, drive main deceleration
Device driven gear, realizes low or high speed step speed change.
The invention has the beneficial effects as follows, combine roller type variable transmission and the advantage of mechanical speed change transmission, reduce
Cart-wheel stepless speed variator at a high speed big load when power attenuation, when reducing mechanical transmission low speed complex road condition and travelling
Energy consumption and operation easier, improve transmission efficiency and reliability, reduce discharge.
