The operational process of the built-in reinforcement rickshaw of two-way double speed of the present invention fool variable shaft is an example to be used as bicycle rear axle, narrates to the rotation direction of being looked in conjunction with the accompanying drawings and according to A in the accompanying drawing.
1. the situation of forward pedaling Middle axle crank
At this moment, transmission shaft 11 is a clickwise, fixes the interior ratchet engagement of ratchet 14 and right end cap 13 on it, and drive shell 18 is advanced vehicle forward, the functional similarity of this and ordinary bicycle flywheel.When housing 18 clockwise rotates, the inner gear 17 of its inner chamber also clockwise rotates, because positioning key 6 is motionless with planetary wheel carrier 2 location, so, make sun wheel 8 rotate counterclockwise by satellite gear 9, certainly, oppositely the driven overcoat 10 of torsion pass overriding clutch also rotates counterclockwise, because the termination of retainer 16 and the oppositely rubbing effect of the driven overcoat 10 of torsion pass overriding clutch, with reverse torsion pass overriding clutch torsion pass part 15, just roller is with the low side to reverse torsion pass overriding clutch imput shaft driving surface, roller is not contacted with the driven overcoat 10 of reverse torsion pass overriding clutch, do not advance forward so can not influence vehicle.
2. in vehicle is advanced the way, stop to scrunch the situation of Middle axle crank
At this moment, housing 18 and right end cap 13 continues to clockwise rotate, and transmission shaft 11 is motionless, and then relative ratchet 14 works of the interior ratchet of right end cap 13 surmount slip, this also with the functional similarity of ordinary bicycle flywheel.In this simultaneously, the inner gear 17 of housing 18 inner chambers also continues to clockwise rotate, and sun wheel 8 and the reverse driven overcoat 10 of torsion pass overriding clutch are rotated counterclockwise, and is identical with above-mentioned situation, therefore, all can not influence vehicle and continue to advance forward.
3. the situation of backward pedaling Middle axle crank
This has two kinds of situations:
(1) vehicle is under stop conditions, the backward pedaling Middle axle crank
Vehicle is motionless, and during backward pedaling, transmission shaft 11 rotates counterclockwise, and the interior ratchet of the ratchet 14 relative right end caps 13 on it does to surmount slip.Transmission shaft 11 rotates counterclockwise, driving retainer 16 also rotates counterclockwise, and sun wheel 8 is motionless, the axial groove that retainer 16 terminations are reversed the face of cylinder on the driven overcoat 10 of torsion pass overriding clutch blocks, push roller to reverse torsion pass overriding clutch imput shaft driving surface high-end, make the roller wedge oppositely between driven overcoat 10 driving surfaces of torsion pass overriding clutch and the reverse torsion pass overriding clutch imput shaft driving surface, become the assembly of torsion pass, sun wheel 8 is rotated counterclockwise, because positioning key 6 is motionless with planetary wheel carrier 2 location, so, by satellite gear 9, make the inner gear 17 of housing 18 inner chambers do cw deceleration rotation, with respect to transmission shaft 11, its reduction ratio is:
And advance forward by the installation limit powered vehicle of housing 18, propulsive effort is increased.
(2) vehicle advance the way in, the backward pedaling Middle axle crank
By as can be known aforementioned, vehicle is when advancing, sun wheel 8 rotates counterclockwise, the backward pedaling Middle axle crank, transmission shaft 11 also rotates counterclockwise, if the conter clockwise rotating speed of transmission shaft 11 is less than the conter clockwise rotating speed of sun wheel 8, then roller can not contact with driven overcoat 10 driving surfaces of reverse torsion pass overriding clutch, in other words when vehicle is advanced with normal speed, the backward pedaling Middle axle crank can not influence vehicle to be continued to advance, have only when the vehicle gait of march is slow, backward pedaling Middle axle crank quickly, make the conter clockwise rotating speed of the conter clockwise rotating speed of transmission shaft 11 greater than sun wheel 8, at this moment, just can make the roller wedge at reverse driven overcoat 10 driving surfaces of torsion pass overriding clutch with oppositely between the torsion pass overriding clutch imput shaft driving surface, and drive sun wheel 8 and rotate counterclockwise, also come powered vehicle to advance forward with regard to the propulsive effort that makes housing 18 obtain increasing.
4. bicycle situation about falling back backward
When bicycle falls back backward, need reversing bar 7 is promoted the keyway that positioning key 6 is broken away from planetary wheel carrier 2 endoporus left.Because, when bicycle falls back backward, housing 18 is to make anticlockwise motion, this will make satellite gear 9 make anticlockwise motion, in this simultaneously, the anticlockwise motion of housing 18, by right end cap 13, transmission shaft 11 and the reverse driven overcoat 10 of torsion pass overriding clutch, make sun wheel 8 also make anticlockwise motion, this but will make satellite gear 9 make clockwise direction and rotate, and to make anticlockwise motion opposite with aforesaid satellite gear 9 for this, if planetary wheel carrier 2 is fixed on the mandrel 3, then motion is stuck, broken away from keyway in planetary wheel carrier 2 endoporus just because of positioning key 6, made planetary wheel carrier 2 on the fitting surface of mandrel 3, make anticlockwise motion, do not fallen back backward so can not hinder bicycle.
The installation situation of the present invention on vehicle is fairly simple, for example, install on the limit in the power transmission of the built-in reinforcement rickshaw of two-way double speed of the present invention fool variable shaft, install spoke and wheel, bicycle, preceding 2 is taken turns back 1 take turns the back vent of tricycle frame or the front fork of wheelchair vehicle carriage, fork tightens up with captive nut respectively and gets final product on the mandrel 3 on variable shaft of the present invention both sides.Take turns back 2 for preceding 1 and take turns three-wheel vehicle, can be with variable shaft of the present invention as intermediary's change-speed box, promptly install on the limit and fix suitable sprocket wheel in the power transmission of housing 18, pitch on mandrel 3 both sides with fixed mount in addition, tighten up with nut respectively, again fixed mount is fixed on position suitable on the vehicle frame, can passes through roller chain, drive the sprocket wheel that is contained on the three-wheel vehicle hind axle and drive three-wheel vehicle.Installation on other gymnastic apparatuss can be carried out with reference to preceding method.
The built-in reinforcement rickshaw of two-way double speed of the present invention fool variable shaft also has some potential functions of use, for example, when needing especially, can be converted to the rotating torque that powered vehicle is advanced to manpower incessantly.The power-actuated vehicle of common people, be to export rotating torque by both feet or both hands rotating crank, when application force passes through the rotation axis of crank, the rotating torque of output is very little, will make vehicle lose propulsive effort, at least also can the short time lose propulsive effort, this can not preceding and then unstability for two-wheeled cycle.And the vehicle of the built-in reinforcement rickshaw of two-way double speed of the present invention fool variable shaft is housed, but can be controlled at crank on the best loading angle, repeatedly with forward and backward pedaling or handly drive by turns, output drive strength square incessantly almost, this is very favourable for powered vehicle under the situation of big resistance; Backward pedaling is equivalent to the walking that falls back, and allegedly human body is benefited; Also have, forward and reverse scrunching by turns can alleviating fatigue etc.
