Abstract
The invention discloses an efficient drive mechanism of a bicycle. The efficient drive mechanism comprises left and right pedals, a main chain wheel, left and right belts and a middle belt; the middle belt is connected between upper and lower reverse wheels; the left belt is connected between a left reverse wheel and a left belt wheel; the right belt is arranged between a right reverse wheel and a right belt wheel; the left and right reverse wheels are respectively assembled at the left and right ends of a first reverse wheel shaft; the upper and lower reverse wheels are respectively assembled on second and third reverse wheel shafts; the upper end of the left pedal is simultaneously connected to the left belt and the middle belt; the upper end of the right pedal is simultaneously connected to the right belt and the middle belt; left and right ratchet wheels are respectively arranged on the left and right belt wheels; an additional wheel connected with the main chain wheel into a whole is arranged on a chain wheel shaft; a left pallet is arranged on the additional wheel; a right pallet is arranged on the main chain wheel; and the left and right ratchet wheels oppositely rotate. The left and right pedals just have linear movement, so that the pedal force acts on the maximal torque part of the main chain wheel all the time, and the maximal torque output is obtained; and the bicycle can also be conveniently stepped to advance under a standing state.
Description
Technical field
The present invention relates to mechanical drive mechanism, especially bicycle driving mechanism.
Background technology
The driver train of existing bicycle comprises pedal, head sprocket, chain and flywheel etc., flywheel is fixed on the wheel shaft of trailing wheel, head sprocket is contained on main chain wheel (bicycle middle shaft), chain is around between head sprocket and flywheel, the power of pedaling of pin is delivered on trailing wheel by parts such as pedal (being equivalent to crank), head sprocket, chain, flywheels, thereby drives bicycle to move ahead.
Because driver sits the pedal that tramps with one's feet on cushion, pedal moves in a circle, the pedaling force direction and can not guarantee all the time perpendicular to the arm of force of pin, under the effect of identical pedal power, the moment maximum normally obtaining in equal height position and when pedal power (supposes that bicycle running is on level road) vertically downward when left and right pedal, and moment in the time that one in the pedal of left and right another is in extreme lower position in extreme higher position is almost nil, mechanical efficiency does not reach maximization.Sometimes in order to improve power, people can habitually adjust the force direction of pedaling of pin with the rotation of step tread, if when inertia is little, it is painstaking and awkward that pin will be felt to front lower place or when the back lower place pedals.In addition, because pedal is to move in a circle, consider the actuation range limitation of pin while being seated by bike, the circular motion radius of pedal can not be done too greatly, and this is also to cause one of reason that common non-variable speed bicycle speed is not high.
Summary of the invention
The object of this invention is to provide a kind ofly under identical pedal power condition, act on moment of torsion on head sprocket consistent, efficiency is higher, and the bicycle high efficiency drive mechanism that facilitates driver to drive with the pedal power of single direction.
In order to realize above-mentioned technical purpose, the technical solution used in the present invention is: a kind of bicycle high efficiency drive mechanism, including left foot pedals, right pedal, head sprocket, left leather belt, right leather belt and mid-belt, head sprocket is connected by main gear chain with the flywheel on bicycle rear shaft, mid-belt is connected between the upper reverse wheel and lower reverse wheel that size is identical, left leather belt is connected between left reverse wheel and left leather belt wheel, right leather belt is connected between right reverse wheel and right leather belt wheel, left reverse wheel, right reverse wheel is assemblied in respectively the left and right end of the first commutation wheel shaft, upper reverse wheel, lower reverse wheel is assemblied in respectively the second commutation wheel shaft, on the 3rd commutation wheel shaft, the upper end that left foot is pedaled is connected on left leather belt and mid-belt simultaneously, and the upper end of right pedal is connected on right leather belt and mid-belt simultaneously, on left leather belt wheel, left ratchet is installed, on right leather belt wheel, right ratchet is installed, left leather belt wheel takes turns with right leather belt the left and right end that is assemblied in respectively main chain wheel, on main chain wheel, kink has the wheel being connected as a single entity with head sprocket, left pawl is installed on wheel to match with left ratchet, right ratchet is installed on head sprocket and matches with right ratchet, left ratchet and right ratchet direction of rotation.
In the time stepping on left foot with left foot and pedal, left foot is pedaled and is driven left leather belt and mid-belt movement, in mid-belt movement process, drives right pedal up; Left leather belt drives left leather belt wheel to rotate, left leather belt wheel drives left ratchet to drive wheel to rotate through left pawl, wheel drives head sprocket to rotate again, head sprocket arrives bicycle rear by main gear chain by transmission of power, bicycle moves ahead, now right ratchet rotates but does not drive right ratchet to rotate with head sprocket, on the impact of right leather belt wheel nothing.In the time that left foot is pedaled arrival bottom dead point, right pedal arrives top dead point, at this moment steps on right pedal with right crus of diaphragm, and right pedal drives right leather belt and mid-belt movement, drives left foot to pedal up in mid-belt movement process; Right leather belt drives right leather belt wheel to rotate, and the right ratchet of right leather belt wheel drive drives head sprocket to rotate through right ratchet, and bicycle moves ahead, and now left pawl rotates but do not drive left ratchet to rotate with head sprocket and wheel, on the impact of left leather belt wheel nothing.Like this, left foot is pedaled with right pedal and is being replaced and moving downward, and left leather belt wheel and right leather belt wheel relay-type ground to head sprocket, make bicycle obtain the power that continues to move ahead transmission of power.
In the present invention, because left and right pedal only has straight-line motion, thereby can make pedal power all act on all the time the maximum torque place of head sprocket, the output of acquisition torque peak, also being convenient to pedal bicycle under standing state moves ahead, for laborsaving and do not affect pedal operation, left and right belt pulley can do greatlyr.
