Embodiment 1: the automobile Severn function automatic variable speed bridge

Over more than 100 year, global automobile people can use a kind of infinitely variable transmission of satisfaction struggling for automobile.

And the inventor thinks, automobile not needs special-purpose gearbox, but the spherical tooth bag in the middle of the automobile drive axle is now become box-shaped, and all speed change component (gearless) all are contained in the case in the ransaxle.Promptly adorned " the thread type two-way controllable overrunning clutch; (patent of invention number: 02108356.8 hereinafter to be referred as clutch); in the middle of two clutches, be equipped with an input shaft synchronous; can be being straight bent axle that becomes the required crank throw radius of operating mode originally when certain rotating speed, and reversible that the differential gear place respectively loads onto my invention originally with engine speed at two (having shortened) semiaxis.Bent axle forces driving lever to produce swing and drives clutch, makes two semiaxis independently produce pulse according to required sense of rotation separately and rotates.The change crank throw radius of automatic stepless, also with regard to the change of automatic stepless the amplitude of oscillation of driving lever, the change of automatic stepless just the semiaxis rotational speed.

So-called " seven functions ", what be meant that (gearless) component of machine with a spot of general precision is combined into is contained in mechanism in the ransaxle case, 1. clutch with present automobile, 2. automatic stepless speed variator, 3. retarder, 4. differential mechanism, 5. the function of break, also has 6. pivot stud (bending) function that present automobile can't have in addition, be automobile turning radius little (theoretical radius is zero), 7. monolateral the wheel by functions such as (as long as having driving wheel on one side and road stone to have friction to pass through slightly).Also the power that transmits to some extent, moment of torsion can unrestricted characteristics etc.

As shown in Figure 1, input shaft 1 and motor direct connection, be equipped with three slide blocks 2 on the axle, middle be the work slide block, both sides be the balance slide block, the cross section of axle 1 is a rectangular section (Fig. 8 shows), respectively there is a V-shaped groove top and bottom of axle, wedge key bar 7 and 7 ' (Fig. 4 respectively are housed in the groove, Fig. 8 shows), it is that the wedge key of a is equipped mutually with cunning separately round as a ball 2.1 that angle is arranged on the wedge key bar, 2.1 under the restriction of positive stop strip 1.1 (Fig. 9 shows), the freedom of the direction displacement of showing along positive stop strip only, like this when up and down wedge key bar 7 and 7 ' axial displacement simultaneously, the angle of wedge direction of wedge key is opposite up and down in same cunning is round as a ball, is separating of h so the center of circle in skid garden 2.1 just produces throw of eccentric with the center line of axle 1, in three slide blocks, middle h is opposite with the h direction on both sides and on same plane, so input shaft 1 has just become plane bent axle as shown in Figure 7.In like manner, screw type structure shown in Figure 6 also can obtain the bent axle that Fig. 7 shows.The structure of unusual fluctuation formula in the same way shown in Figure 5 can obtain the bent axle that Fig. 7 shows too.

Input shaft 1 and motor direct connection, when rotating speed is lower than idling speed n1, the pretension elastic force of tensile force f＜spring 9 (Fig. 4 shows) that modulator (A, B, C type) produces, then input shaft still keeps initial straightened condition, and promptly motor is in idle running.But behind rotating speed＞n1, straight input shaft just transforms to bent axle, and the size of crank throw radius is directly proportional with the height of engine speed.

After the bent axle on the input shaft 1 formed, it rotated and just to force multi pack cunning thereon round as a ball 2.1, and slide block 2 produces swing.Being contained in the wooden fork of dialling wooden fork 3 of slide block 2 Spielpassung, its swing force with the driving lever 3.1 of dialling wooden fork 3 one under the restriction of dialling wooden fork mechanism axle center 8.Can only make reciprocally swinging, just become swing to amplify actuator.The driveshaft 4.1 that drives on the clutch is worked clutch 4 normally.Be that the ALT pulse that semiaxis 5 is carrying out on the microcosmic is rotated, because mass of system inertia, what show on macroscopic view is independently to rotatablely move uniformly separately.

How does modulator work?

A type directly pulling type modulator: as shown in figure 13, be associated with flexible body A1 on wedge key bar 7 and 7 ' the link rod 7.1, it links with flying piece A3 accordingly on the pulley A7 of support A2, flies piece A3 and is sleeved on the guide rod A5, and guide rod A5 is associated on the disk A4.A4 and support A2 are associated on the input shaft 1, be that guide rod A5 is with input shaft 1 rotation, the centrifugal force that flies piece A3 becomes the axial tension to link rod 7.1, the elastic force of wedge key bar 7 and 7 ' overcome spring 9 produces axial displacement, force three round as a ball 2.1 radial displacements of cunning, form bent axle shown in Figure 7, obviously the crank throw radius R in the bent axle with fly piece A3 radial displacement and be directly proportional, and the radial displacement of A3 is to be directly proportional with engine revolution, the amplitude that also is the each reciprocally swinging of clutch is directly proportional with engine speed, also is that the revolution of semiaxis 5 is directly proportional with engine speed.

In Fig. 4, Fig. 5, in the ordinary course of things, wedge key bar 7 and 7 ' angle of wedge a value can self-lockings in 5～7 ° of scopes, can not satisfy the demand if fly the displacement amount in rolling garden 2.1 this moment, then strengthen a value, for still can self-locking, can wedge key bar 7 and 7 ' friction surface make the decorative pattern of certain shape etc. or adhere to method such as high coefficient of friction material at the friction position and increase friction factor between friction surface, increase after the value of a angle still can reliability the increase self-locking.

If increase the method for friction surface friction factor when inapplicable, it is constant that the mode that can adopt Figure 14, train shown in Figure 15 to amplify guarantees to fly piece A3 stroke, and wedge key bar 7 and 7 ' stroke enough big.Also can adopt the spiral modulator that shows among Figure 16, Figure 17; Fly the radial displacement of piece A3, earlier become rotatablely moving of spool gear B1.1 by tooth bar B2 because screw rod B1 and spool gear are one, the rotation of B1 then become wedge key bar 7 and 7 ' axial displacement.Amplification by train with should fly piece A3 stroke limiting system the time satisfies screw rod B1 enough revolutions, makes the enough displacement stroke of wedge key bar 7 and 7 ' obtain.

Except directly pulling type and wheel bar amplifying type control methods, also can adopt electromagnetic type modulator as shown in figure 20.Among the figure, guide rod C1 and bearing outer ring C3 link, and be inserted among the axially directed groove C2, bearing inner race C5 and wedge key bar 7 and 7 ' link, one of armature C6 and bearing outer ring C3 link, the other end places spiral-type DC electromagnet C7, direct current required among the electromagnet C7 is supplied with by the DC generator on the automobile, when one timing of the electromagnet coil number of turn, the electric current [strength that generator is supplied with also promptly is directly proportional with engine speed with generator, also be that electromagnet C7 is that engine speed is directly proportional to the suction that armature C6 produces with generator speed, when the pretightening force of suction≤spring 9, armature C6 does not produce and moves axially, after the pretightening force of attraction force＞spring 9, then armature C6 drives wedge key bar 7 and 7 ' and produces axial displacement, and displacement amount is directly proportional with engine speed.Bearing inner race C5 is with wedge key bar 7 and 7 ', and also promptly along with output shaft 1 high speed rotating, because the centrifugation of ball C4, bearing outer ring C3 can only do axial displacement because of guide rod C1 in guiding groove C2, and the armature C6 that links with outer ring C3 also can only do axial displacement.

Above-mentioned three kinds of modulators all are the big or small stepless variations of only controlling throttle, have also just determined the stepless variation of speed of a motor vehicle speed.

How do seven kinds of functions realize?

1. clutch function---talk about in aforementioned, when engine speed is lower than the idling revolution, fly attraction force that centrifugal tension that piece A3 produces or electromagnet C7 produce all≤pretightening force of spring 9, then input shaft 1 still is a straight axle, promptly motor (input shaft) is in idle running.Also promptly dialling wooden fork 3 does not work, semiaxis is certain and engine rotation is irrelevant, be equivalent to power cut, when engine speed＞idling speed, fly the pretightening force of the centrifugal tension or the attraction force＞spring 9 that electromagnet C7 produces of piece A3 generation, be that wedge key bar 7 and 7 ' produces axial displacement, straight input shaft 1 has originally become bent axle, and the size of crank throw radius is directly proportional with the rotating speed of input shaft 1, crank throw on the input shaft 1 forces and dials wooden fork 3, driving lever 3.1 begins swing, driving clutch also is that semiaxis is done the pulse rotation, and promptly power is connected.Engine revolution≤idling revolution under usual operating mode, then power cut, engine revolution＞idling revolution then power is connected.

2. stepless speed variator.3. retarder function:---become big or diminish because the crank throw radius is a size with the attraction force of the centrifugal tension of A3 or C7, it is the amplitude of fluctuation of driving lever 3.1, it also is clutch 4, the angle that semiaxis 5 each pulses are rotated is directly proportional with engine speed, engine speed changes with the stepless variation of throttle, like this, the stepless variation of throttle just make semiaxis 5 also the pulse that changing of automatic stepless rotate revolution.Just the high speed rotating of motor has been become the low speed pulse rotation of semiaxis 5.The amplitude of oscillation is semiaxis revolution height greatly then, otherwise opposite.

4. differential mechanism function---because two clutches are intermittently useds alternately, semiaxis is also just done the alternately pulse rotation at intermittence like this, owing to be that ALT pulse is rotated, promptly a semiaxis is initiatively, meanwhile, it is passive that another semiaxis has just become, passive obedience initiatively, rotate once pulse constantly can be variant and mutual noninterference watching for such two semiaxis.Promptly played the effect of differential mechanism.

5. break---as Figure 10, Figure 11, shown in Figure 12, kinetic friction dish (sheet) F1 that semiaxis 5 first line of a couplet, follow axial alternate the loading in mixture of static friction dish (sheet) F2 that links with pontic, power source F3 utilize gas, liquid, electromagnetism, machinery or its compound friction disk (sheet) is compressed or separates to come semiaxis 5 is produced braking or semi-brakes, both can be used to be used as the descending retarder, also can be used as break.Can certainly adopting radially, chuck formula friction clutch is used as break.

6. pivot stud (bending) function---owing on two semiaxis 5 a thread type two-way controllable overrunning clutch is housed respectively, in the ordinary course of things, automobile only depend on hold steering wheel just can realize turning (to), under special circumstances as: the road narrows place does not allow automobile to have enough ground to turn to (bending), this moment driver's direction controlling rod that only need make a movement, make one in the thread type two-way controllable overrunning clutch that is contained on the two-semiaxle still to keep just changeing, another then reverses and just can, Ci Shi turn inside diameter radius can equal zero in theory, can be the center of circle with the ransaxle center, rotate to arbitrarily angled.

7. monolateral the wheel can be passed through function---and present automobile falls into places such as the minimum water of frictional force, ice, snow, mud, sand if run into driving wheel on one side, just be difficult to pass through, and among the present invention, because two semiaxis are independently being done ALT pulse separately and are being rotated, this moment is as long as have one side to also have frictional force with the road surface in two driving wheels, and another cincture promptly is the frictional force that loses fully with the road surface, and automobile still can advance also having under the driving of driving wheel of frictional force with the road surface.
