When driving dual planetary gear 2 rotations when sun gear 1 (input shaft) acquisition power (calling active force in the following text), its power will act on respectively on planetary carrier 3 and the differential gear 4.(1) if the rotational resistance of differential gear 4 less than the rotational resistance person of planetary carrier 3, dual planetary gear 2 acquisitions are fulcrum from the active force of sun gear 1 with two fork handles on the planetary carrier 3, only finish from transferring not have revolution, the rotating speed of planetary carrier 3 (output shaft) is 0 to dual planetary gear 2 rotation active forces by forcing differential gear 4 counter-rotatings with differential gear 4 gear teeth, no matter design given its velocity ratio i value size, the speed changer of this moment is the clutch of a separated state.(2) if to brake 5 soft stoppers on differential gear 4 cylindricals of the speed changer in this separated state work, make rotational resistance on the differential gear 4 greater than the rotational resistance of planetary carrier 3 until not changeing, the rotary action power that this moment, dual planetary gear 2 was obtained is fulcrum (precession activity supporting point) steadily enters the displacement rotation from the original place rotation revolution state with differential gear 4 gear teeth, revolution produces angle speed promotion planetary carrier 3 (output shaft) and rotates thereupon, speed changer becomes from clutch decides ratio speed reducer, and its velocity ratio i is given as K by the traditional formula design.(3) if brake 5 stoppers discharge, driving speed change regulation and control gear pair 6 with a power source (calling secondary power in the following text) by free wheel device 7 makes differential gear 4 external tooths interlock internal tooth rotate, controlling its internal tooth (essence is dual planetary gear 2 revolution rotating speeds) does and can be slower than, equal, faster than the design given gear ratio value K speed discrepancy-n, 0n, + n, promptly give dual planetary gear 2 another power of input by the external tooth interlock internal tooth of differential gear 4 with another secondary power source, acting in conjunction is done in planetary carrier 3 and is slower than or faster than the angle of K speed difference n, at this moment, this speed changer is two mixed power clutch, be again two power-actuated CTV of mixing, velocity ratio i can be at K+ (n) (reduction of speed), K+0n (constant speed), K+ (+n) change in (raising speed) scope, by intelligent ECU regulation and control, realize the CTV function.
Be not difficult to find out, the active force that drives dual planetary gear 2 work is prime mover of a constant speed, the secondary power source that drives speed change regulation and control gear pair 5 must be steady at any time, progressive, infinite variable speed prime mover, with regard to current automobile power machine technology development, two mixed power, promptly based on oil, with electricity is that the power engine of assisting has become the market development orientation, with frequency modulation, the adjustable magnetic technology realizes that infinite variable speed actuating motor can undertake two mixed power easily, the mission of differential speed regulation, has clutch so this a kind of CTV is congenital, device arranged side by side, the speed changer compatibility condition, it is heavy little to embody specific volume, economize than cost, than the high superiority of reliability.The stepless speed variator that this a pair of mixes the power differential speed regulation particularly is suitable for the two mixed power vehicle speed changers of work.
Description of drawings
Fig. 1 is a stepless speed variator main structure schematic representation of the present invention.
Embodiment
Basic structure of the present invention is made up of eight parts such as sun gear (input shaft), planetary pinion, planetary carrier (output shaft), differential gear, brake, speed change regulation and control gear pair, free wheel device, gear reversing devices.
4 gear pairs of internal tooth of its sun gear 1 of stepless speed variator of two mixed power, differential speed regulation, dual planetary gear 2, differential gear 4 are continuously-meshing gear in the accompanying drawing 1, dual planetary gear 2 is moving to be placed on two fork handles with the planetary carrier 3 of sun gear 1 coaxial line, and 1,2,3,4 four parts is main members.
1. with the clutch speed reducer of clutch mode work, this one speed reducer is made up of sun gear 1, dual planetary gear 2, planetary carrier 3, differential gear 4 and brake 5.When stopper power discharges, because of planetary carrier 3 (output shaft) hang with the load rotational resistance big, differential gear 4 rotational resistances are little, give sun gear 1 (input shaft) input power, at this moment, the active force that dual planetary gear 2 obtains is the original place spinning motion that fulcrum does not have revolution with two fork handles of planetary carrier 3, drives the differential gear 4 internal tooth crop rotation return motions of often nibbling, planetary carrier 3 does not have the revolution transmission of power and output speed is 0, and retarder is worked with the clutch separation state; Start and to finish the back along with to the brake 5 soft stopper power that apply, make differential gear 4 decrescence rotating speed until not changeing, dual planetary gear 2 was forced to the displacement rotation and was that fulcrum forms revolution and promotes planetary carrier 3 (output shaft) rotation with differential gear 4 internal tooths this moment, the output shaft rotating speed can steadily rise to till the given velocity ratio i=K, the clutch closure, retarder enters normal working.
The clutch speed reducer of this pattern is easy to be reliable and be applicable to that high power motor, internal combustion engine start connect with the steady of gearing down with it, and its advantage is that stopper power can soft, intermittently regulation and control, eliminates the burst impact that causes because of startup.
2. with the stepless speed variator of regulation and control model work, as described in 1., different is: in cancellation brake 5 differential gears 4, the outer ring all is a gear, the external gear of outer ring and speed change regulation and control gear pair 6 are often nibbled, making secondary power source with internal-combustion engine or speed-adjustable motor is connected through free wheel device 7 and speed change regulation and control gear pair 6 and makes differential gear 4 internal tooth controlled rotation, give dual planetary gear 2 road power source in addition, appearance is revolved round the sun with dual planetary gear 2, and activity supporting point is controlled to be slower than, equal, differential n faster than design given planetary carrier 3 (output shaft) rotational angle speed K, thereby it is constant and the revolution rotating speed changes by secondary power association is moving to finish dual planetary gear 2 rotation rotating speeds (main power machines rotating speed), finishes the stepless variation that planetary carrier 3 (output shaft) rotating speed is done or fallen or rise.
At present, because oil, the two mixed power vehicle development of electricity have become market-oriented, obviously, with frequency modulation, adjustable magnetic motor is that particularly necessity and tool are easy, reliable inevitable for side by side two mixed motivational drives of secondary power, when the design given this stepless speed variator basic point K velocity ratio i similar in appearance to traditional speed changer one or second gear person, secondary power motor drives speed change regulation and control gear pair 6 with a certain rotating speed and drives differential gears 4 and do the differential of isogonism speed difference with respect to planetary carrier 3, and active force is kept transmission output shaft to be similar to one or the second gear rotary speed working in the economic speed scope; If operating conditions changes, increase secondary power motor rotating speed (exerting oneself) at random, give the revolution faster rotational speed of dual planetary gear 2, the speed changer output speed rises to approximate high tap position or falls revolution speed and remains unchanged to approximate a certain gear, the instant velocity ratio i of this stepless speed variator can the velocity ratio i=K+ that is kept (n), i=K+0n, i=K+ (+n) in proper functioning.
The stepless speed variator of the mixed power of this pair, differential speed regulation, oil, electricity or electricity, oily two-way power drive side by side, do not need synchronously, the major-minor position can exchange; If be active force person with electric power in two mixed power, the secondary power source that then drives 6 work of speed change regulation and control gear pair is an internal-combustion engine, electrical machinery of active force does not need frequency conversion, becomes the magnetic speed governing therebetween, speed change regulation and control gear 6 secondary power source--the internal-combustion engine speed change has inherent advantage, stepless speed regulation configuration seem simpler province and nature.
The automobile of single power source, if it is in service because of power engine fault or oil starvation (nothing), vehicle is had to helplessly cast anchor, and the major and minor power source in the two mixed power of the present invention all has the advantage of single power emergency operation, when breaking down or during oil starvation (nothing) in one of two-way power source road, the input shaft of fault one tunnel stopper of meeting an urgent need, dynamic one road folk prescription input is emergent to be driven, than the time speed changer with velocity ratio i=K (low-grade location) transferring power, drag automobile away certain distance, finish and save oneself.
Usually, automobile has neutral gear, reverse gear function with speed changer, two mixed power of the present invention, its speed change regulation and control gear pair 6 of differential speed regulation stepless speed variator are connected a free wheel device 7 with secondary powerhouse, be low to moderate under the state of certain value at no secondary power or rotating speed, start main power source, sun gear 1 operation, planetary carrier 3 is because of big differential gear 4 counter-rotatings of load resistance, free wheel device skids, and planetary carrier 3 (output shaft) does not change, and is exactly neutral gear; Then start secondary power source or acceleration and reach certain value, the free wheel device proper functioning, differential gear 4 does not change or just changes, and planetary carrier 3 (output shaft) has rotating speed, puts into gear exactly; As for reverse gear, can finish by conventional arrangement reverse gear 8 and operating device.
Go to realize with automatic control means in view of this stepless speed variator is many, therefore, seem extremely important especially with the cooperation of car ECU function.
