Description
The present invention is the mechanical transmission that is applied in the power transmission.
During the differential gear train torque converter transmission, turn round in the scope in its change, constant when input power, it can produce and the outer torque coupled mutually of carrying, and made output power invariable when changing in outer year.In fact it is a kind of automatic stepless speed variator that torque and output speed are inversely proportional to of exporting, and is applicable to the transmission occasion that output speed and external load often change.
The present invention is with reference to red flag board car CA770 automatic transimission; The torque converter function is made, through preliminary search, the mechanical transmission aspect does not still have this thing both at home and abroad, can consult the 110th page of " engineering machinery hydraulic and hydraudynamic drive " book volume two of writing in schools such as Jilin Industry University about the torque converter in the hydraudynamic drive technology similar to the present invention, this data is published by China Machine Press, China Machine Press's printing house printing.In July, 1979 Beijing front page, in July, 1979 Beijing first impression, standard book number 15033.4830.
Task of the present invention: can both reach permanent power transmission for making all vehicular traffics, tractor, tank, boats and ships driving, engineering machinery etc., improve the Economy and the power factor of prime mover, thereby remedy and replace torque converter in this deficiency of using on the one hand and narrow limitation.
Fig. 1 is the basic driving mechanism in the differential gear train torque converter: epicyclic gear train mechanism.In this mechanism, gear ring (2) central gear (3) can both be rotating around fixed axis OO.When central gear (3) rotated, planet wheel around the axis revolution of oneself, turned round around fixed axis OO with tie-rod (1) again on the one hand on the other hand.In epicyclic gear train mechanism, three three basic dirivig members that can both be referred to as epicyclic gear train mechanism around the rotating tie-rod of fixed axis OO (1), gear ring (2), central gear (3), and this three member all moves.Essential to after wherein the motion of two members is determined, the athleticism of the 3rd member is determined, if wherein central gear (3) initiatively, gear ring (2) is fixing, tie-rod (1) is driven, and the transmission of such epicyclic gear train mechanism is referred to as Gear Planet Transmission, and it has only one degree of freedom; If tie-rod (1) initiatively in three members, central gear (3), gear ring (2) are driven, and such epicyclic gear train mechanism driving is referred to as differential drive, and it has two degrees of freedom, it can resolve into two motions with a motion, two motions can be synthesized a motion again.
The differential motion transducer that Fig. 2 is made up of two epicyclic gear train mechanisms.Two their gear ring of epicyclic gear train mechanism and gear rings among the figure, central gear and central gear link one and form two connection pieces respectively, gear ring (2) and central gear (3), wherein the tie-rod of an epicyclic gear train mechanism (1) initiatively is input, the tie-rod of another epicyclic gear train mechanism (4) is driven for exporting.Because in the epicyclic gear train mechanism, gear ring on planet wheel both sides (2) and central gear (3) are stressed to be average, so tie-rod of differential motion transducer (1) or tie-rod (4), active force on driving link or the driven member or reaction force, it all is equilibrium conditions by planet wheel, by the planet wheel mean allocation or return feed two connection piece gear rings (2) and central gear (3), so this two epicyclic gear train mechanism seals binding like this, two have binary box of tricks, retrained the self-locking one mutually by the member gear ring (2) of two stress balances and central gear (3), make the input of mechanism directly become output.Obviously between gear ring (2) and the central gear (3) if when losing equilibrium of forces, understand because of unbalance stress moving variation between member.Maintained static by external force as gear ring (2), this moment, one epicyclic gear train mechanism did the speedup transmission, and another epicyclic gear train mechanism makes gearing down, all converts ordinary transmission simultaneously to.Mechanism has only one degree of freedom, the external force suffered as if gear ring (2) is not enough so that it maintains static, differential motion transducer two epicyclic gear train mechanisms can both convert differential drive to from ordinary transmission again, wherein tie-rod (1) initiatively, the driven mechanism that makes of tie-rod (4) and gear ring (2) has two degrees of freedom.
Fig. 3 is the differential gear train torque converter schematic diagram, and it is by a differential motion transducer, and an epicyclic gear train mechanism and freewheel are assembled in the casing to be formed.Gear ring among the figure in the differential motion transducer (2) and tie-rod (4) link one with the gear ring of an epicyclic gear train mechanism and central gear respectively, tie-rod in the differential motion displacer (1) is the power input end of differential gear train torque converter, tie-rod in the epicyclic gear train mechanism (5) is the power take-off of differential gear train torque converter, and freewheel is to be used for placing restrictions on the device that gear ring (2) can only be done unidirectional movement.Its active star-wheel (6) is fixed as one with gear ring (2), be fixed as one from moving sleeve (8) and differential gear train torque converter casing (9), but star-wheel (6) can be subjected to driving link tie-rod (1) to do unidirectional movement with gear ring (2), is subjected to roller (7) during counter-rotating acts on wedging gear ring (2) is maintained static.
According to differential motion transducer and epicyclic gear train motion of mechanism characteristics, the combination of these two kinds of mechanisms, can utilize stressed the varying in size of differential motion transducer gear ring (2) to have the ability of converting motion form, two members in planet wheel both sides in its two output members gear ring (2) and tie-rod (4) and the epicyclic gear train mechanism are linked.Can reach gear ring in the differential gear train torque converter mechanism (2) and tie-rod (4) like this because of the stressed purpose that equates to cause gear ring (2) and central gear (3) force unbalance.As long as the output torque of differential gear train torque converter mechanism is greater than input torque, each member of mechanism must be adjusted balance because of mutual unbalance stress self and move variation.As seen the differential converter is in differential gear train torque converter, and it is a kind of fractional horse-power driving mechanism, and it can resolve into an input power two power that size can be changed.And epicyclic gear train mechanism is in differential gear train torque converter, synthesize an output to two power that the former decomposes so long, so differential gear train torque converter is united two into one by these two kinds of mechanisms, its kinetic characteristic is as long as there is torque differences in input with output, fully reflects in the scope no matter how this torque differences size can both be turned round in its change.
Starting period, prime mover carry by static setting in motion outward at full capacity.Moment driven member tie-rod (5) is gone up load and is returned feedback and distribute to slip maximum on gear ring (2) and the central gear (3) in the opplied moment of gear ring (2) and tie-rod (4) and driving link tie-rod (1), the opposite motion of direction takes place with central gear (3) in gear ring this moment (2) in slip, because freewheel effect gear ring (2) is fixed on the casing (9) by wedging, under the supporting of casing (9), obtain maximum reaction force and make mechanism's stress balance, force each train of differential gear train torque converter mechanism all to make ordinary transmission simultaneously, velocity ratio reaches maximum.
After the starting, outer year inertia on the driven member tie-rod (5) increases the generation acceleration, starting torque is reduced at once, the last load of driven member tie-rod (5) is returned the torque of feedback on gear ring (2) and is also reduced, when the torque of this feedback is enough to make opplied moment on the driving link tie-rod (1) directly to drive it to rotate, under the situation that the original machine power factor remains unchanged, surplus power begins the fractional horse-power transmission.Gear ring (2) produces motion throws off from freewheel, and each train of differential gear train torque converter mechanism all converts differential drive to from ordinary transmission, impels output speed to improve velocity ratio and reduces.Load acceleration on the driven member tie-rod (5) continuation subsequently improves corresponding continuation of torque differences and reduces, and load is returned the equilibrium of forces that feedback influences mechanism once more.Surplus power is many from reducing to the fractional horse-power transmission of gear ring (2), the variation that goes round and begins again like this, velocity ratio reaches balance until input power and output power, output speed settle out or driving link tie-rod (1) on torque equal torque on the driven member tie-rod (5), mechanism's input could be determined when self-locking becomes direct transmission in equilibrium of forces with exporting.Be understood that differential gear train torque converter turns round in the scope in its change, input power is constant, and it is a kind of permanent power driving mechanism, and it can not only be with the automatic conversion type of belt drive of load size, and can change velocity ratio with the load acceleration change, the realization automatic stepless speed change.
Torque converter and differential gear train torque converter all are permanent power transmission devices, can amplify the moment of torsion of prime mover.Their difference place, torque converter are to be transmission medium with liquid, and liquid flow impact power is the driving mechanism of transmitted power, so the contradiction that has flow and flow velocity and volume size between the coefficient is turned round in its transmission efficiency and change.Make its change turn round scope and placed restrictions on, can not be too big, again because of hydraudynamic drive through transformation of energy.Power will be subjected to loss, so hydraudynamic drive is not as good as the machinery driving efficiency height.
And differential gear train torque converter is a kind of gear drive, its deceleration multiple and moment of torsion magnification factor are approaching, so transmission efficiency is higher, adds mechanical Gear Planet Transmission and has bigger velocity ratio, thereby make the change of differential gear train torque converter turn round the expansion that scope can not placed restrictions on.
Structure and manufacture view, the manufacturing requirement of hydraulic transmission component and cost are all than machinery part height in addition, and a series of structures such as the heat radiation of torque converter, compensation, control are less than differential gear train torque converter mechanism compactness, never there is the variation that causes service behaviour because of reasons such as sealing and leakages in differential gear train torque converter in the use, and it is definitely strong than hydraudynamic drive to put into practice mechanically operated as can be known reliability.
Differential gear train torque converter mechanism is the same with the retarder and the speed changer of conventional machinery ordinary transmission, it all is driving mechanism independently, therefore implement the present invention and can directly use above working principle, according to purposes and watt level or by the performance requirement and the mounting point of match mechanism device and facility, be dimensioned to each serial stepless speed variator.
