Description

A kind of long cone tapper formula infinitely variable speed gearing
Technical field
The present invention relates to the mechanical continuously-variable transmission field, be specifically related to a kind of long cone tapper formula infinitely variable speed gearing.
Background technique
The plurality of advantages such as mechanical continuously-variable transmission has simple in structure, and reliability is high, and stepless speed regulation is convenient are used more have cone pulley type, planetary cone wheel formula, belt, chain type and pulsed etc. at present.The long cone of mechanical type tapper formula infinitely variable speed gearing has been subject to paying close attention to widely and studying in recent years, still, large innovation and breakthrough is arranged seldom on the structure.
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; In the nearest more than ten years, CVT (Continuously Variable Trans-mission) stepless speed variator technology has obtained very large progress, is widely used in the small-power automotive field, still, the restriction that it is subject to strip material and technology makes manufacture cost very high.
Conical pulley variable-speed device 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, its have stable drive, noise little, simple in structure, overload protection effect, the advantage such as various informative are arranged, use at present more have 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.; When cone pulley is done load and friction work with the transmission component that is touched in the cone pulley friction type stepless speed changer, 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, make to produce between two rolling elements 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 conical pulley variable-speed device, 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, be can not produce how much to slide in theory, the transmission efficiency of this moment is also the highest; But 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 at present comparatively ideal solution.
In sum, the present invention proposes a kind of new structure of mechanical continuously-variable transmission, can 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; When for example the length in Contact Transmission district was 10mm between cone pulley and the cone pulley among the present invention, 1 to 1 time how much of velocity ratio slided=0, the maximum geometry slip ﹤s 0.04 of velocity ratio in 1 to 0.4～2.5 scopes; How much slips of the present invention in whole adjustable gear range are very little, almost can ignore, but the quality of Effective Raise product and usefulness can adapt to the working condition requirement of various gearings better, and conical pulley variable-speed device of the same type can't be accomplished at present.
Uncontrolled along with the unlimited rising of the development of world industrial economy, the sharp increase of population, human desire and the mode of production and life, global climate and energy consumption face more and more serious problem, in order to tackle global warming issue, the whole world is all at the related measure of carrying out the low-carbon energy-saving environmental protection, especially at automotive field, country makes the development that a lot of preferential policies are supported industry.The present invention can realize the gear ratio that the motor winding number is desirable as the vitals of transferring power, and can realize without impact, smooth and easy level and smooth variable transmission and the raising of fuel efficiency; Apply along with of the present invention, make outstanding contributions for the low-carbon energy-saving field of Environment Protection, particularly have larger contribution in fields such as automobile, motorcycle, electric motor cars.
