Mainly bring the stepless variation that realizes speed ratio by main ﹑ follower and the metal of reducing with driving buncher, transmission efficiency Gao ﹑ slewing range is wider, can realize stepless change in quite wide scope, thereby obtain the optimum Match of power train and engine operating condition, improve the fuel economy of car load.But, be subject at present the restriction of strip material and technology, make manufacture cost very high.
The cone pulley friction type stepless speed changer mainly carries out transmission by contact friction and the lubricant film traction of driving and driven rigid member (perhaps passing through intermediary element), and can carry out stepless change by the radius of clean-up that changes its contacting point; It has stable drive, noise little, simple in structure, overload protection effect, the advantage such as various informative arranged; At present, widely used mainly containing: cone disc annular disc type, multi-disc type, steel ball conical pulley, pyramid type, Hang Xing Cone disc type and planet circular cone type stepless speed variator etc.; But, in the cone pulley friction type stepless speed changer when cone pulley and the transmission component that is touched are done load and friction work, owing to the reason of cone pulley and the transmission component geometrical shape that is touched makes the velocity distribution of two rolling element contact areas different, between two rolling elements, can produce and slide for how much, the traction temperature is risen how much slips in the mechanism and traction coeficient reduces, thereby cause speed changer driving force and decrease in efficiency etc., the wearing and tearing that also can accelerate simultaneously pulling face cause the speed changer life-span to reduce.
In the prior art, in order to reduce the spin phenomenon of friction driving contact area in the cone pulley friction type stepless speed changer, numerous artificers can be according to the size of transmission power, dwindle cone pulley as far as possible and the transmission component that is touched between the contact area, to reduce geometric slide rate; If the geometric slide rate in the cone pulley friction type stepless speed changer can be reduced to minimum, only have when the contact area between cone pulley and the transmission component that is touched during for the some contact, in theory just can not produce and slide for how much, the transmission efficiency of this moment is also the highest,, less its bearing capacity in contact area between cone pulley and the transmission component that is touched is just poorer, and transmission power is also less; Below produce contradictory phenomena between the two, how to solve above-mentioned technical problem, in this field, also do not have comparatively ideal technological scheme.
In sum, be necessary to develop a kind of new cone pulley friction type stepless speed changer, between the transmission component that increases cone pulley and be touched in the contact area, can reduce again the geometric slide rate in the cone pulley driving mechanism, solve the contradictory phenomena in the above-mentioned cone pulley friction type stepless speed changer, improve quality and the usefulness of product, can adapt to better the working condition requirement of various gearings.
