Five, embodiment:
Please see Figure 1 to Fig. 6, the utility model is mainly by input shaft 1, bearing 2, active cone pulley 3, Transmitted chains 4, movable initiatively cone pulley 5, spring 6, little duplicate gear 18, passive cone pulley 20, movable passive cone pulley 21, weight 22, connecting rod 23, stationary axle 25, compositions such as spring 26 and output mechanism, wherein initiatively cone pulley 3 is fixed on the input shaft 1 that stretches into casing 27, movable initiatively cone pulley 5 through the spline kink on input shaft 1, initiatively cone pulley 3 and the movable V-type groove that initiatively forms between the cone pulley 5 are formed initiatively wheels, form the V-type groove between passive cone pulley 20 and the movable passive cone pulley 21 and form passive wheels, initiatively wheels connect passive wheels through driving belt 4, it is characterized in that: the A. initiatively movable initiatively cone pulley 5 of wheels is supported by spring 6, the passive cone pulley 20 of passive wheels is fixed on the sleeve 14, movable passive cone pulley 21 through the spline kink on sleeve 14, and by spring 26 supports, the elastic force of passive wheels spring 26 is much larger than the elastic force of active wheels spring 6; B. sleeve 14 kinks are on stationary axle 25, and there is boss the other end to its one, is hinged with weight 22 on its boss through gear connection output mechanism, and an end of articulated linkage 23 on the weight 22, the other end of connecting rod 23 are hinged on movable by on the dynamic bevel gear 21; C. the Transmitted chains 4 that connects the active wheels is combined through bearing pin 33 by chain link 28, and the inclined-plane 31,32 of each chain link 28 both sides forms V-types, and this V-type matches with the V-type groove of active wheels and passive wheels.
As can be seen from Figure 5: output mechanism is by input shaft 1, output shaft 7, big duplicate gear 8, speed of a motor vehicle instrument output gear 10, universal joint 11, bearing pin 12, slide block gear 13, sleeve 14, reverse gear 17, little duplicate gear 18, overrunning clutch 19 is formed, wherein a headgear of output shaft 7 is contained in the input shaft 1 that stretches into casing 27, output shaft 7 other ends are stretched out casing 27 and are connected universal joint 11, be connected with big duplicate gear 8 on the output shaft 7 in the casing 27, on the output shaft 7 between big duplicate gear 8 and the universal joint 11 speed of a motor vehicle instrument output gear 10 is installed, big duplicate gear 8 and slide block gear 13 engagements of kink on bearing pin 12, gearwheel engagement on slide block gear 13 and the duplicate gear 18 that is connected on the sleeve 14, small gear on the duplicate gear 18 and reverse gear 17 often mesh.When slide block gear 13 moves right, the right gear engagement with reverse gear 17 and big duplicate gear 8 realizes anti-phase transmission, and vehicle is realized reversing.
It can also be seen that from Fig. 5: overrunning clutch 19 is installed on the passive cone pulley 20 of passive wheels, and vehicle falls back and vehicle preshoot when going up a slope reversing in the time of can preventing hill-start.
As can be seen from Figure 6: output mechanism is made up of input shaft 1, bearing pin 12, sleeve 14, single gear 38, intermediate gear 39, gear 40, sprocket wheel 42, common chain 41, kink was at the output terminal of input shaft 1 after its middle gear 40 was connected as a single entity with sprocket wheel 42, sprocket wheel 42 is connected with wheel through common chain 41, gear 40 often meshes with the intermediate gear 39 of kink on bearing pin 12, and intermediate gear 39 often meshes with the single gear 38 that is connected on the sleeve 14.
Working principle of the present utility model is: being installed on the automobile with this device is example, certainly, this device also can be installed on other motor vehicle such as the motorcycle, start motor car engine, the car engine mechanomotive force drives input shaft 1 and rotates, input shaft 1 drives the active wheels of being made up of active cone pulley 3 and movable initiatively cone pulley 5 simultaneously and rotates, initiatively wheels Transmitted chains 4 drives the passive wheels rotation of being made up of passive cone pulley 20 and movable passive cone pulley 21, because the movable passive cone pulley 21 on the passive wheels is spacing by spring 26, and the elastic force of spring 26 is the movable initiatively elastic force of cone pulley 5 upper springs 6 on the active wheels, therefore when not having other external force effect, spring 26 is always pressed to passive cone pulley 20 with the passive cone pulley 21 of activity, passive wheels are worked under maximum working radius, and movable active this moment cone pulley 5 is at the squeezing action lower compression spring 6 of driving belt 4, the active wheels are worked under the minimum radius of clean-up, retarder is in maximum low speed state, is equivalent to vehicle starting or low speed driving state.
When the speed of a motor vehicle rises, the rotating speed of passive wheels raises, the weight 22 that be hinged on sleeve 14 boss this moment opens under centrifugal action, and passive cone pulley 21 pressure springs 26 of drivening rod 23 pulling activities, movable passive cone pulley 21 is moved to the direction of leaving passive cone pulley 20, this moment, driving belt 4 increased the radius of clean-up to the active wheels under the effect of spring 6, passive wheels reduce the direction change of the radius of clean-up, the speed changer speedup, be equivalent to automobile to high speed, the high tap position speed change, the speed of a motor vehicle is high more, to high tap position direction speed change, the speed of a motor vehicle is low more for speed changer, and speed changer is to low-grade location direction speed change, because this variation is level and smooth stepless, therefore can realize the automatic stepless speed change of automobile.
In speed-change process, passive cone pulley 20 drives little duplicate gear 18 rotations on the sleeve 14, little duplicate gear 18 drives slide block gear 13, slide block gear 13 drives big duplicate gear 8, big duplicate gear 8 drives output is changeed 7, output commentaries on classics 7 is arrived automobile differential through universal joint 11 with transmission of power, drives automobile and advances.
Because the small gear and the reverse gear 17 of little duplicate gear 18 often mesh, when slide block gear 13 moves right, gearwheel and the reverse gear 17 of 13 whiles of slide block gear with little duplicate gear 18 meshes, the small gear of the little duplicate gear 18 on the sleeve 14, drive big duplicate gear 8 backward rotation through reverse gear 17 and slide block gear 13, realize rolling-back of car.
When slide block gear 13 mediates, break away from engagement with big duplicate gear 8, the driving force of sleeve 14 can not be delivered on the output shaft 7, and at this moment automobile is in neutral state.
The effect of overrunning clutch 19 is only to allow sleeve 14 to rotate to driving direction, does not allow to rotate round about, automobile is not produced when going up a slope starting fall back, and preshoot does not take place when descending is moveed backward.
Fig. 6 is seen in application on motorcycle, sleeve 14 skies are enclosed within on the stationary axle 25, gear 38 is fixed on the sleeve 14, gear 38 is by gear 39 (sky is enclosed within on the axle 12), be transferred to gear 40 (sky is enclosed within on the input shaft 1), sprocket wheel 42 is an integral body with gear 40, and sprocket wheel is by the sprocket wheel of common chain transmission to the wheel, thereby the drive wheel travels.
When this model utility is used on other motor vehicle, still belong to protection domain of the present utility model.
