The specific embodiment
As shown in drawings, the utility model comprises:
1) on the output shaft 2 of driving engine 1, be equipped with engine output shaft 2 affixed, opening is towards " U " shape friction disc 3 in the driving engine outside, five equilibrium is connected with several centrifugal springs 8 that connect friction shoe 7 respectively on engine output shaft 2, another " U " shape friction disc 6 outer five equilibriums are connected with several another the centrifugal spring 5 that connects another friction shoe 4, another " U " shape friction disc 6 openings are towards the driving engine inboard, be embedded in friction shoe 7 and opening towards between " U " shape friction disc 3 inboards in the driving engine outside, on the output shaft 10 of another " U " shape friction disc 6 outer side center miniature gears 9 is housed, on the output shaft 10 of miniature gears 9 both sides bearing is housed respectively;
2) at transmission shaft 17 another miniature gears 18, big gear wheel 11 and output chain gear 12 are housed respectively, transmission shaft 17 both sides are equipped with bearing respectively, miniature gears 9 engagements on big gear wheel 11 and another " U " shape friction disc 6;
3) pin treading wheel axle 14 both sides are equipped with pin respectively and are stepped on crank 13, and another big gear wheel 15 that links to each other with overriding clutch 16 is arranged on the pin treading wheel axle 14, another miniature gears 18 engagements of another big gear wheel 15 and transmission shaft 17, and pin treading wheel axle 14 both sides are equipped with bearing respectively.
Said several centrifugal springs 8 and several another centrifugal spring 5 are 2～20.
Principle of work of the present utility model is as follows:
(1) situation of engine retard driving:
Centrifugal spring 8 is housed on the output shaft 2 of driving engine 1, friction shoe 7 links to each other with centrifugal spring 8, when engine speed reaches setting value, friction shoe 7 is under action of centrifugal force, overcome the effect of centrifugal spring 8, work with friction disc 6, driving friction disc 6 rotates, friction disc 6 drives output shaft 10 and rotates, and output shaft 10 drives output pinion 9 again and rotates, and miniature gears 9 drives big gear wheel 11 and rotates, big gear wheel 11 drives output chain gear 12 by transmission shaft 17 and rotates, output chain gear links to each other with drive sprocket on the bicycle rear, drives car and advances, and the reduction ratio of driving engine is by the ratio of number of teeth decision of miniature gears 9 and big gear wheel 11; Transmission shaft 17 also drives miniature gears 18 rotations simultaneously, and miniature gears 18 drives big gear wheels 15 and rotates, owing to big gear wheel 15 is installed on the pin treading wheel axle 14 by overriding clutch 16, so big gear wheel 15 idle running, do not drive 15 rotations of pin treading wheel axle; When the rotating speed of driving engine did not reach setting value, the centnifugal force of friction shoe 7 was not enough to overcome the application force of centrifugal spring 8, made friction shoe 7 and friction disc 6 break away from, and the output shaft 2 of driving engine is being with friction shoe 7 idle running, not transferring power; The engine speed that works can be realized by the predetermincd tension of the centrifugal spring 8 of adjusting and the quality of rigidity and friction shoe 7.
(2) situation of inertia starting driving engine:
When the speed of car reaches setting value, need be by engine drive, during fire an engine, system is work like this: the inertia of car drives sprocket wheel 12 rotations, sprocket wheel 12 drives big gear wheel 11 rotations by transmission shaft 17, big gear wheel 11 Drive pinions 9 rotate, miniature gears 9 drives output shaft 10 rotations, output shaft 10 drives friction disc 6 rotations, be connected with centrifugal spring 5 and friction shoe 4 on the friction disc 6, when the speed of car reaches setting value, just friction disc 6 reaches when setting rotating speed, friction shoe 4 is under action of centrifugal force, overcome the effect of centrifugal spring 5, work, drive friction disc 3 and rotate with friction disc 3, friction disc 3 drives output shaft 2 and rotates, thus fire an engine 1; The speed of the car of fire an engine can realize by the predetermincd tension of the centrifugal spring 5 of adjusting and the quality of rigidity and friction shoe 4; The situation work of describing according to above-mentioned (1) again after driving engine 1 starting.
(3) pin is stepped on the situation of riding and starting:
When fuel is used up, do not had electricity, is out of order or reason that certain is special, bicycle with mixed drive power can also pin be stepped on and is ridden and start, specific as follows: people's pin is stepped on pin and is stepped on crank 13, driving pin treading wheel axle 14 rotates, pin treading wheel axle 14 drives big gear wheel 15 by overriding clutch 16 and rotates, big gear wheel 15 Drive pinions 18, miniature gears 18 drives output chain gear 12 rotations by transmission shaft 17, output chain gear 12 links to each other with drive sprocket on the bicycle rear, the driving car advances, and the over-speed gear ratio that pin is stepped on is by the ratio of number of teeth decision of big gear wheel 15 and miniature gears 18; Transmission shaft 17 also drives big gear wheel 11 rotations simultaneously, big gear wheel 11 drives miniature gears 9 and rotates, miniature gears 9 drives friction disc 6 by output shaft 10 and rotates, friction disc 6 drives friction spring 5 and friction shoe 4 rotations again, when the rotating speed of friction disc 6 is lower, when just the speed stepped on of pin was low, the centnifugal force of friction shoe 4 was not enough to overcome the effect of centrifugal spring 5, friction shoe 4 breaks away from idle running with friction disc 3, and the realization manpower is ridden; When the rotating speed of friction disc 6 is enough high, when just the speed stepped on of pin is enough high, the centnifugal force of friction shoe 4 overcomes the effect of centrifugal spring 5, friction shoe 4 combines with friction disc 3, drive friction disc 3 rotations, friction disc 3 drives output shaft 2 rotations again, and output shaft 2 rotation fire an engines 1 realize riding starting.
