Description

A kind of Gun Lun Cone disc type stepless speed changer
Technical field
The present invention relates to mechanical continuously-variable transmission field, be specifically related to a kind of Gun Lun Cone disc type stepless speed changer.
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, apply more have cone pulley type, planetary cone wheel formula, belt, chain type and pulsed etc. at present.
Mainly bring by main ﹑ driven gear and the metal of reducing the stepless variation that realizes speed ratio 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 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 (or 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, have overload protection effect, the advantage such as various informative, apply 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 in cone pulley friction type stepless speed changer, cone pulley does load and friction work with the transmission component being touched, because cone pulley makes the velocity distribution of two rolling element contact areas different with the reason of the transmission component geometrical shape being touched, make can produce and slide for how much between two rolling elements, how much slips in mechanism can make traction temperature rise and traction coeficient reduce, thereby cause speed changer driving force and decrease in efficiency etc., the wearing and tearing that simultaneously also can accelerate pulling face cause the speed changer life-span to reduce.
In prior art, in order to reduce the spin phenomenon of friction driving contact area in 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 contact area, to reduce geometric slide rate; , if the geometric slide rate in cone pulley friction type stepless speed changer will be reduced to minimum, only having when the contact area between cone pulley and the transmission component that is touched is during for some contact, is can not produce how much to slide in theory, and transmission efficiency is now also the highest; But less its bearing capacity in contact area between cone pulley and the transmission component that is touched is just poorer, transmission power is also less; Below produce contradictory phenomena between the two.
A long Cone rolls cone type stepless variable speed unit and has been subject to extensive concern and the research of transmission field in recent years, in structure, also there are larger innovation and breakthrough, by changing the shape of intermediate roller, make the identical and Contact Transmission of the conical degree of conical surface direction of the first conical surface on intermediate roller and long cone pulley initiatively, the second conical surface on intermediate roller and the conical degree of conical surface direction of driven long cone pulley also identical and Contact Transmission, this stepless speed variator has obviously reduced the geometric slide rate that transmission produces, and has improved transmission efficiency and power; But the intermediate roller in this stepless speed variator, in the time that the conical surface that is parallel to master/slave moving long cone pulley regulates speed change, can produce larger axial resistance or end thrust, cause mechanical efficiency and life-span to be reduced.How to solve above-mentionedly, in this field, also there is no at present comparatively ideal solution.
Technical problem in sum, the present invention proposes the Novel variable speed structure of Yi Zhong Cone dish cart-wheel stepless speed variator, drive at least one intermediate roller to rotate around active cone pulley by a support, change the position between intermediate roller upper driving particle, intermediate roller automatically produces and moves axially, and change continuously the velocity ratio between active cone pulley and driven cone pulley, realize infinite variable speed object with the method for simple and fast; Can also, by increasing the quantity of intermediate roller and driven cone pulley, reduce the length of intermediate roller transmission particle, in reducing geometric slide rate, can also improve transmission efficiency and power; Intermediate roller in the present invention moving axially all in transmission and speed-change process automatically regulates under self adaption state, perfectly solve intermediate roller being parallel to the axial resistance (or end thrust) producing when initiatively the conical surface of long cone pulley regulates speed change, improved complete machine mechanical efficiency and working life.
The present invention possesses good composite behaviour, by on the described cone pulley support of being arranged on of multiple described driven gear symmetries and respectively with described ring gear (or described central gear) engagement driving, any one in described active cone pulley, described cone pulley support and three elements of described ring gear (or described central gear) is as fixed block, any one in another two is as driving link, last forms a single stage type planetary wheeling mechanism as driven member; The present invention has further improved slewing range and transmission power, by the cooperation between three elements, can obtain six kinds of different stepless change outputs, and can realize wider range of infinitely variable speeds just/anti-output function; The present invention has broken through existing planetary gear transmission mechanism can not infinite variable speed technical bottleneck.
The advantages such as the present invention is as the vitals of transferring power, and slewing range is large, and can realize without impact, smooth and easy level and smooth variable transmission, and transmission efficiency is high, and transmission power is large; Apply along with of the present invention, one makes outstanding contributions for low-carbon energy-saving field of Environment Protection surely, particularly has larger contribution in fields such as automobile, motorcycle, electric motor car and mechanical transmission.
