Abstract
The utility model relates to a pedal chain type driving mechanism of a manpower vehicle, which comprises a bicycle inherent drive mechanism besides a pedal. The utility model is characterized in that two flywheels 12 are added on both ends of a middle axle; a main body member is fixed on the lower part of a support frame 2 between the middle axle 11 and a back axle 5 by a base; a four-bar linkage mechanism is formed by a left and a right pressure levers on the main body member and a connecting rod. The pedal chain type driving mechanism of a manpower vehicle adopts a swinging lever type power starting mode, and the swing angle of the pressure levers is 60 DEG. The effective power of force transmission is enhanced largely. Compared with the ordinary crank rotary type power starting mode, the utility model can save one-third labor, and the speed can increase 0.5 time. The utility model is convenient to reform an original used vehicle, and has the advantages of compact structure design, low cost and convenient and easy installation, which is suitable for the reformation and the new vehicle manufacture of all manpower pedal vehicles.
Description
The utility model belongs to transportation means, B62M 9/02 class, a kind of pedal of bicycle and chain drive mechanism.
Current, the bicycle that people generally use is started and operation by foot-operated crank circle Zhou Xuanzhuan.This power the way of initiating makes the effective rate of utilization less than 70 percent of manpower, and forming the dead angle when crank and ground when vertical, makes to start difficulty, and transmitted power is reduced to zero.For overcoming this shortcoming, many schemes have appearred, be preferred version wherein with pedal swinging formula and straight line power the way of initiating, as the novel patent GN2061925V of China number and CN203897, their common feature is after axis is moved to vehicle seat, and weak point is that its enforcement all will be transformed existing main body of vehicle frame, can only be used to manufacture and design the car of novel model, and not attractive in appearance, must cancel the back shelf.
The purpose of this utility model provides a kind of not only applicable to existing car but also can be used for manufacturing and designing the pedal chain formula driver train of new car.
The pedal chain formula driver train of this rickshaw comprises the intrinsic transmission device of bicycle except that stretcher, it is characterized in that adding two flywheels 12 at the axis two ends, support 2 bottoms between axis 11 and rear axle 5 utilize base fixing main component; Main component comprises two concentric imput shaft 3, is fixed on the riser hole of base, is also fixing an elongated universal driving shaft 22 on it, the universal driving shaft two ends fixing trace 14,14 ', their other end respectively articulated positive connecting rod 18, anti-connecting rod 18 '; Positive connecting rod 18 other ends are pressed an end of the hinged positive depression bar 15 of certain angle, anti-connecting rod 18 ' connecting depression bar 8; Depression bar 15,8 other ends are connecting pedal 9 respectively with meeting at right angles, the hole that cooperates with imput shaft 3 is arranged respectively on the depression bar 15 and 8, the hole that cooperates with imput shaft on the depression bar 8,15 to the distance of connecting rod 18,18 ' hinge hole should equal the width between centers of trace 14,14 ' two stomidiums, is fixed with two sprocket wheels 6 respectively in reverse direction; The flywheel 12 that depression bar 15,8 passes through on sprocket wheel 6 and chain 13 and the axis 11 in the main component constitutes the pedal chains driving, and the sprocket wheel 10 on the axis 11 is by the 16 formation sealed joint transmissions of the flywheel on chain 17 and the trailing wheel.
The utility model has adopted rocking lever formula power the way of initiating, and the depression bar pivot angle is 60 °, so the bigger transmission effective power that has improved power compares laborsaving 1/3rd with the power the way of initiating of common crank rotary type.Onesize acting, speed increases by 0.5 times, forms laborsaving fast speed characteristics.This utility model project organization compactness, cheap, it is easy to utilize original used car to transform, and installs easily, is applicable to all manpower bicycles' transformation and new car manufacturing.
Accompanying drawing 1 is this car integral structure scheme drawing;
Accompanying drawing 2 is the Middle shaft assembly scheme drawing of driver train;
Accompanying drawing 3 is four lever linkage scheme drawings of main component;
The pedal chain formula driver train of this rickshaw, comprise the intrinsic transmission device of bicycle except that stretcher, it is characterized in that respectively adding a flywheel 12 at chip sprocket wheel 10 and axis two ends, support 2 bottoms between axis 11 and rear axle 5 utilize base fixing main component; Main component comprises two concentric imput shaft 3, is fixed on the riser hole of base, is also fixing an elongated universal driving shaft 22 on it, the universal driving shaft two ends fixing trace 14,14 ', their other end respectively articulated positive connecting rod 18, anti-connecting rod 18 '; Positive connecting rod 18 other ends are pressed an end of the hinged positive depression bar 15 of certain angle, anti-connecting rod 18 ' connecting depression bar 8; Depression bar 15,8 other ends are connecting pedal 9 respectively with meeting at right angles, and the hole that cooperates with imput shaft 3 is arranged respectively on the depression bar 15 and 8, and there is the convex edge inboard, hole, and outside thread is arranged on the convex edge, with the screw-internal thread fit of sprocket wheel 6; Be fixed with two sprocket wheels 6 respectively in reverse direction two depression bar inboards; Constitute the running part of main component by imput shaft 3, depression bar 8,15, sprocket wheel 6.Imput shaft 3 should make the smallest limit position of depression bar 15,8 be on the extended line of saddle intubate with the relative center of axis 11, so select: a, depression bar effective rake L=2 * prototype crank effective rake, b, the best pivot angle of depression bar=60 °.
During following trampling bar, sprocket wheel 6 is rotation simultaneously both, drives axis flywheels 12 by chain 13 and reaches flywheel 16 on the trailing wheel by chain 17 again, makes the trailing wheel rotation, the bicycle operation.The flywheel 12 that depression bar 15,8 passes through on sprocket wheel 6 and chain 13 and the axis 11 in the main component constitutes the pedal chains driving, and the sprocket wheel 10 on the axis 11 is by the 16 formation sealed joint transmissions of the flywheel on chain 17 and the trailing wheel.The interlock of left and right sides depression bar is achieved in that the two ends of gangbar 22 are fixed with the left gangbar 14 of certain angle ' and right gangbar 14 on the main component, and left and right sides gangbar and left depression bar 8, right depression bar 15 are respectively by positive connecting rod 18 and anti-connecting rod 18 ' link to each other with connecting pin 20.The pitch-row of positive 18 liang of stomidiums of connecting rod equals the width between centers between imput shaft 3 and the universal driving shaft 22, the hole that cooperates with imput shaft on the depression bar 8,15 to the distance of connecting rod 18,18 ' hinge hole should equal the width between centers of trace 14,14 ' two stomidiums, constitutes positive parallelogram lindage; Anti-connecting rod 18 ' and gangbar 14 ' and base constitute anti-four-bar mechanism.Two groups of above-mentioned four-bar mechanisms because of about interlock and the positive and negative four bar linkage of the fixing formation of universal driving shaft 22.Left depression bar 8 is in the limes superiors position in the accompanying drawing 3, right depression bar 15 is in the smallest limit position, when left depression bar 8 presses down, by the rotation of anti-connecting rod 18 ' make universal driving shaft 22 anticlockwise directions, then right gangbar 14 is left-hand revolution together also, rise by the right depression bar 15 of positive depression bar 18 pullings, this has just constituted the interlock of left and right depression bar.
