Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
A kind of embodiment's of the utility model transmission principle, as shown in Figure 1.
This kind mechanical transmission, comprise output or import the transmission shaft 1 that rotatablely moves, applicator 5, first auxiliary pulley 41 that is positioned at movable pulley 6 both sides and second auxiliary pulley 42 of exporting or import straight-line movable pulley 6, connection movable pulley 6 centers of circle, and the driving belt 3 that transmits the pulley room active force.Described transmission shaft 1 is fixedlyed connected with the clutch 2 of single effect, and is provided with resetting-mechanism.Described first auxiliary pulley 41 and second auxiliary pulley 42 are separately fixed on first track 91 and second track 92, and can along separately track do in opposite directions or from mobile, distance each other can be regulated.One end of described driving belt 3 is fixed, and is wrapped on the described clutch 2, is docile and obedient described first auxiliary pulley 41 of preface pile warp, movable pulley 6, second auxiliary pulley 42 again, and the other end is fixed on end points 8.When applicator 5 drives movable pulley 6 moving linearlies,, drive transmission shaft 1 and rotate by the transmission of driving belt 3 and being connected of clutch 2; When transmission shaft 1 rotates,, produce straight line motion by applicator 5 in the center of circle of movable pulley 6 by the connection of clutch 2 and the transmission of driving belt 3.
Its working principle is: provide straight-line power source by applicator 5 to movable pulley 6, when applicator 5 acts on the movable pulley 6, when arrow direction, drive driving belt 3 motions, after auxiliary pulley change direction, act on the clutch 2, driven rotary axle 1 rotates.When applicator 5 stopped to do work, clutch 2 and movable pulley 6 can reset under the effect of resetting-mechanism.Because the one-way clutch characteristic of clutch 2, transmission shaft 1 can keep original sense of rotation constant.The reset mode of resetting-mechanism can be used Returnning spring, also can form linking mechanism with two groups of same transmission devices, and one group of transmission device drives another group transmission device and resets in acting.Above-mentioned transmission process constitutes a cycle of motion.Change the straight line back and forth movement into if will rotatablely move, then must select controllable clutch for use, as magnetic clutch.
The utility model embodiment's force analysis as shown in Figure 2.
Characteristics of the present utility model are to adopt two auxiliary pulleys and a movable pulley 6 to constitute a variable-angle Y shape force structure.In Fig. 2, F1 is the size that acts on the power on the movable pulley.F2 and F3 are respectively the size through the suffered power of the driving belt 3 of movable pulley 6 both sides, and angle A and angle B are respectively movable pulley 6 both sides driving belts 3 and the reciprocal angle of the application of force of applicator 5.Because F2 equals F3, supposes that angle A equals angle B, so:
F2＝F1/(cosA×2)
This shows that under the constant situation of F1, the size of F2 is relevant with angle A, A is more little at the angle, and F2 is more little; Angle A is big more, and F2 is big more.And the ratio of the straight-line speed of movable pulley 6 and the rotational velocity of transmission shaft 1 can change with the variation of angle of entry A.
Regulate its position owing to auxiliary pulley can move along track, thereby changed the force direction that is subjected to of driving belt 3, velocity ratio is changed, reach the purpose of electrodeless variable-speed.Track can be selected straight line or curve, and curve is the best with the elliptic curve track, because auxiliary pulley can keep driving belt 3 rates of tension constant when mobile on elliptical orbit.
Fig. 3 is two groups of same transmission devices of the utility model resetting-mechanisms each other, be applied in the transmission principle on the bicycle, at this moment, transmission shaft 1 is the rotating shaft of cycle wheel, the applicator 5 that acts on movable pulley 6 is for foot-operated, driving belt 3 pile warps of every group of transmission device clutch 2 backs separately link to each other by a static pulley 7, and such batter is stepped on when down motion drive transmission shaft 1 rotates, and the transmission device of opposite side just resets.
Fig. 4 is two groups of same transmission devices of the utility model resetting-mechanisms each other, is applied in the transmission principle in the two stroke clutch release slave cylinder mechanisms.At this moment, the applicator 5 that acts on movable pulley 6 is the piston of clutch release slave cylinder, and the driving belt 3 of two groups of transmission devices links to each other by static pulley 7 with different direction pile warp clutch 2 backs, and its working principle is the same.
Fig. 5 is two groups of same transmission devices of the utility model resetting-mechanisms each other, is applied in the transmission principle in the four-stroke clutch release slave cylinder mechanism.At this moment, the applicator 5 of every side is two also coefficient four-stroke cylinder pistons that link to each other.
About clutch 2, need select different clutches for use according to the occasion difference of using.
As be used for bicycle, and do not need reversing, can select ratchet or free wheel device for use.Be used for automobile, then need to select for use controllable clutch 2 as magnetic clutch.When the acting one side transmission device clutch be in jointing state, when the clutch 2 of the side transmission device that resets was in separated state, transmission shaft 1 was just changeing; When the clutch 2 of acting one side transmission device is in separated state, when the clutch of the side transmission device that resets is in jointing state, transmission shaft 1 counter-rotating.
By the separation or the jointing state of solenoidoperated cluthes 2, can also realize reverse transmission, the rotation that is about to transmission shaft 1 changes the round straight line motion of movable pulley 6 into.The rotation of transmission shaft 1 can be changed into the round straight line motion of piston during as automobile brake, play the effect of braking, kinetic energy can be converted to other energy storage simultaneously.
