Below in conjunction with Fig. 1, Fig. 2 basic functional principle of the present invention is further described.
Pulsed stepless speed-regulating device of the present invention has two driving shafts i.e. first driving shaft 1 (hereinafter to be referred as axle 1) and second driving shaft 2 (hereinafter to be referred as axle 2), is positioned on the same geometrical axis O O, at the not ipsilateral of casing.Have crank R and R ' and taper cone pulley 3 or 4 (at axle 1 wheel 3 is arranged, at axle 2 wheel 4 is arranged, taper cone pulley 3,4 also can adopt the side steering of being made up of cylindrical gears, as Fig. 3) on each axle.Taper cone pulley 3 and 4 and taper cone pulley 5 engagement, its axis is on casing.Taper cone pulley 3,4 and 5 forms the taper side steering.Like this, the axle 1 and 2 and the taper reversing mechanism get in touch each other.This means, if the rotation of axle 1 clockwise direction, then just rotation counterclockwise of axle 2.Axle 1 is connected with 7 with rocking bar 6 with 2 crank R, R ', and rocking arm has bearing 9.Bearing 9 is arranged on the slide block 8 same geometrical axis O1 O1 of (being equivalent to manually or the foot-propelled shift), and slide block 8 can move (not representing controlling mechanism on Fig. 1) in Vertical direction by corresponding controlling mechanism.Bearing 9 guarantees that rocking bar 6 and 7 is free movable in swing and progressive motion.Rocking bar 6 correspondingly is connected with 11 with connecting rod 10 on A1 and A2 point with 7.The other end of each root connecting rod is connected with 13 with rocking bar 12.Correspondingly, rocking bar 12 and 13 is contained on the transmission output shaft 16, they have part ratchet D, two ratchet D and wheel 14,15 interact, it (is one-way wheel that wheel 14 or 15 is called the contrary wheel of system, be used for live axle 16 folk prescriptions to rotating), the ratchet D of rocking bar 12 above being installed in him and system form the ratchet driving mechanism against wheel 14 (rocking bar 13 also takes turns 14 with position ratchet D thereon with system is contrary), so that only transmission is from connecting rod 11 or 10 rotations to axle 16 (according to Fig. 1 clockwise direction) in one direction, ratchet and pawl arrangement herein also can adopt and be similar to the free wheel device of installing on the bicycle rear (abbreviation flies) and realized.
Ratchet mechanism among Fig. 1 can adopt the similar products of specialized company's professional production.
The working principle of pulsed stepless speed-regulating device of the present invention is: 1 and 2 on axle is swung, and has only one to be driving shaft in each time period.For example, suppose that at set period axle 1 be driving shaft, at this moment axle 1 in the clockwise direction the rotation in the swing cause taking turns 14 rotations, that is to say that axle 16 also is a clockwise direction, and ratchet mechanism can not pass to motion 16 during the anticlockwise rotation of axle 1.Because axle 1 and 2 is each other with the contact of taper reversing mechanism, so axle 1 clockwise rotation will cause axle 2 counterclockwise to rotate, therefore this rotation can not passed to axle 16.On the contrary, axle 1 anticlockwise rotation will cause axle 2 clockwise directions to rotate, and this rotation causes axle 16 rotations.Like this, axle 1 is swung sideward to move and is caused axle 16 to rotate on same direction.
Pulsed stepless speed-regulating device of the present invention is realized stepless change by the displacement of sliding support 8 or by the length that adjusting is cranked arm, shown in Fig. 1,6 is that displacement by sliding support 8 realizes stepless speed regulation, and at this moment rocking bar 6 and 7 arm are than changing synchronously.Like this, when the amplitude of fluctuation of crank R (and R ') fixedly the time, the amplitude of fluctuation that A1 and A2 are ordered changes on the direction of needs, thereby the amplitude of fluctuation of rocking bar 12 and 13 changes, and this means in a swing of these rocking arms, and the rotation angle of axle 16 also changes.Development test shows, motionless when A1 and A2 point, the position of sliding support 8 also may change.This means that axle 16 is still motionless when axle 1 amplitude of fluctuation is constant.Like this, in institute's stepless speed variator of the present invention, regulation range can be 1 at gearing factor (when the mid point of sliding support 8 positions) in rocking bar 6 and 7 to equaling realization in infinitely great (when sliding support during) scope at A1 and A2 point.
When bearing 9 when maintaining static, can adopt the crank arm device of R length of the change shown in Fig. 4 of the present invention, 5 to realize stepless adjustment, the length of R or R ' can steplessly be adjusted owing to crank arm, therefore, input speed as gear can infinitely be adjusted, and its output also correspondingly increases in proportion or reduces.
In order to guarantee above-mentioned stepless speed changing mechanism energy proper functioning, internal-combustion engine of the present invention and ordinary internal combustion engine also should be had any different.Piston in the conventional cylinder makes bent axle rotate under fuel vapor pressure, and cylinder piston of the present invention can make bent axle only swing, and this is to be determined by the working principle of above-mentioned gear.
As shown in Figure 2, suppose that piston diameter is d, piston stroke is that h and length of connecting rod are 1 connecting rod, and by d, the same condition of h and 1 parameter forms connecting rod in two kinds of internal-combustion engines, from these two kinds of internal-combustion engines relatively, in Fig. 2, allow the crank of bent axle r in piston stroke h with pendulum angle for example 90 ° swing, at this moment be not difficult to find out, to be positioned at the O1 point be the center of circle to the oscillation center O of crank point in this connecting rod, and radius is on the circle of h/2.
In general, the pendulum angle of crank will depend on the position of crank rotating center at OO1 straight line or its elongation line.Those crank turning point are referred to as the eccentric internal combustion machine for the internal-combustion engine that the O1 point is subjected to displacement, and the distance of ordering to O from the O1 point is referred to as throw of eccentric.As understanding from following argumentation, when matching with the pulsed stepless speed-regulating device, throw of eccentric can be selected any number of zero that is not equal to, and still, it should be consistent with the work of internal-combustion engine gas distribution shaft.
The piston motion mechanism that cylinder of internal combustion engine of the present invention moves back and forth as shown in Figure 2, the power that crank r affacts on the piston is P, its component is Pc, and component Pc is pressed to cylinder wall to piston, and when determining piston motion and the size of the frictional force that produces between the cylinder wall.Component Pc is the function of the angle of deviation β of connecting rod and vertical line n O1.Be not difficult to find out that angle of deviation β is significantly smaller than the angle of deviation of traditional air cylinder connecting rod in air cylinder connecting rod of the present invention.In swing type crank-connecting rod piston set of the present invention, the minimizing of angle means that the frictional force work also will descend, this just can be so that the fretting wear of piston and cylinder reduces accordingly, its durability is improved accordingly, mechanical efficiency is also improved accordingly, thereby brings the minimizing and the lower series of advantages such as calorific intensity loss of part of fuel consumption.
Above-mentioned pulsed stepless speed-regulating device forms the major component of the internal-combustion engine that the present invention recommends with crank-swinging formula explosive motor.The other parts of these transmissions (as end shelves, differential mechanism or the like) do not have the structure innovation, although its parameter is different, the prior art that maybe can adopt all same as the prior art is solved, and therefore, is not also indicated in appended schematic representation.
Embodiment three.
As shown in Figure 7.
The transmission device (Fig. 7) of the single internal-combustion engine of a kind of four-stroke four cylinders contains the cylinder P1 according to its job order numbering, P2, P3, P4.The pulsed stepless speed-regulating device is installed in the transmission device in such a way; Cylinder P4 and P2 are positioned at the pulsed stepless speed-regulating device first, and cylinder P1 and P3 are positioned at another then.The driving shaft 1 of pulsed stepless speed-regulating device links to each other with swing type crank 4 with plain connecting rod 3 with 2, and the amplitude of fluctuation of crank 4 ' is got α=90 °.
