Abstract
The utility model belongs to a bicycle which mainly provides a positive and negative pedaled bicycle. The utility model is mainly characterized in that both sides of a middle shaft and a main shaft are provided with clutches, springs, big chain wheels and pedals. Clutch claws are arranged between the clutches and the big chain wheels, and shifting forks, steering bracing cables of the shifting forks and handles are arranged between the clutches. Both sides of a rear shaft are provided with positive pedaled flywheels and negative pedaled flywheels, and two transition wheels are arranged beside the negative pedaled flywheels. One end of a negative pedaled chain is wound on the negative pedaled big chain wheels, the other end is wound on the transition wheels, and the transition wheels are pressed on the negative pedaled flywheels by the negative pedaled chain. The utility model has the characteristics that the bicycle can move forward with positive pedaling, and when the handles are wrenched, the bicycle can move forward with negative pedaling. The waist, the legs, etc. can obtain more effective full exercises.
Description
The utility model relates to a kind of bicycle, particularly a kind of just pedaling or bicycle that back-pedalling can both make bicycle move ahead.
At present, the bicycle that people use all has only cover sprocket wheel, chain and a flywheel gear, promptly just pedaling the actuating device that moves ahead, and be not provided with the actuating device that back-pedalling moves ahead, its weak point is that the pedal mode is single, make the bicyclist keep a kind of athletic posture, can not carry out comprehensively waist and shank, actv. takes exercise, susceptible was to tired when particularly long distance was ridden.
The purpose of this utility model provided a kind of both can just having pedaled to move ahead at above-mentioned weak point exactly, but the positive back-pedalling that moves ahead of the back-pedalling bicycle that moves ahead again.
Technical solution of the present utility model is: a kind of positive back-pedalling bicycle that moves ahead, comprise front and rear wheel, vehicle frame, handlebar, vehicle seat and just pedaling chain, it is characterized in that: the axis main shaft both sides that are fixed on the axis axle sleeve are provided with the positive and negative power-transfer clutch of pedaling successively, positive and negative hinge wheel and the pedal pedaled.Be provided with spring between an axis axle sleeve and the power-transfer clutch.Positive and negative pedal power-transfer clutch respectively and positive and negative pedaling be provided with the positive and negative clutch claw of pedaling that cooperatively interacts between the hinge wheel.The positive and negative power-transfer clutch of pedaling is provided with shift fork and break-in drag-line and break-in handle.The rear axle both sides are respectively equipped with and just pedal flywheel and back-pedalling flywheel, and the other warp of back-pedalling flywheel fixedly transition wheel support is provided with two back-pedalling transition wheels.Back-pedalling chain one headring is on the back-pedalling hinge wheel, and the other end is looped around on the back-pedalling transition wheel, and the back-pedalling chain is pressed on the back-pedalling flywheel.
The positive and negative contact surface of pedaling clutch claw described in the utility model technical solution can be the inclined-plane.
The utility model is owing to set up a cover back-pedalling hinge wheel, back-pedalling flywheel, back-pedalling transition wheel and back-pedalling chain device, positive and negative pedaling is provided with positive and negative power-transfer clutch, shift fork, break-in drag-line warp and the break-in handle pedaled between the hinge wheel, therefore, generally, the back-pedalling clutch claw interlock between power-transfer clutch and one of them hinge wheel such as the back-pedalling hinge wheel, then just pedaling clutch claw leaves, at this moment, the back-pedalling pedal, the back-pedalling chain drives the back-pedalling flywheel just to be changeed, bicycle is moved ahead, just pedaling hinge wheel idle running; Pull the break-in handle, can make and just pedal the clutch claw interlock, the back-pedalling clutch claw leaves, and at this moment, is just pedaling pedal, is just pedaling chain and is driving and just to pedal flywheel and just change, and bicycle is moved ahead, the idle running of back-pedalling hinge wheel.Compared with prior art, the utility model has overcome the deficiencies in the prior art part, make constantly conversion athletic posture of bicyclist, swing, make waist and shank can access more effective all round exercise, and recreational stronger, ride and can not feel very tired all the time, thereby reached the purpose of this utility model.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1 and Figure 2.Axis main shaft 20 is fixed in the axis axle sleeve 25.Its left side is provided with spring 26, back-pedalling power-transfer clutch 27, back-pedalling hinge wheel 12 and pedal 13 successively; The right side is provided with successively and is just pedaling power-transfer clutch 22, just pedals hinge wheel 3 and pedal 13.The positive and negative power- transfer clutch 22,27 of pedaling is provided with fixing screw 17, cooperates with knock hole 18 on being arranged on axis main shaft 20, prevents its random slip.Axis main shaft 20 is provided with two rectangular slots 24, and guide finger 23,30 is slided in rectangular slot 24.Be provided with the back-pedalling clutch claw 28 that cooperatively interacts between back-pedalling power-transfer clutch 27 and the back-pedalling hinge wheel 12, its contact surface is the inclined-plane that cooperatively interacts, and can make it engage more firmly like this.The clutch claw of back-pedalling shown in the figure 28 is an engagement state.Equally, just pedal power-transfer clutch 22 and just pedaling also to be provided with between the hinge wheel 3 and just pedaling clutch claw 21.Collar 19,29 can block positive and negative hinge wheel 3,12 location of pedaling.Locating piece 15 is fixed on the V-type central frame beam by its fixed orifice 32.Shift fork 16 passes locating piece 15, and two ends are enclosed within positive and negative pedaling on the power- transfer clutch 22,27, and two ends is provided with set pin 31, so that install.Shift fork 14 is fixed on the locating piece 15, is connected with break-in handle 1 on being fixed on handlebar by break-in drag-line 2.Positive and negatively pedal the two ends that flywheel 5,10 is fixed on rear axle, cooperate with the positive and negative hinge wheel 3,12 of pedaling respectively.Fixing transition wheel support 8,9 V-shaped rear axle left end axle heads that are fixed on, back-pedalling transition wheel 6,7 are separately fixed at fixedly on the transition wheel support 8,9.Just pedaling chain 4 is just pedaling hinge wheel 3 and is just pedaling on the flywheel 5 around a circle.Back-pedalling chain 11 on back-pedalling hinge wheel 12 and back-pedalling transition wheel 6,7 around a circle, and with top, the outside of back-pedalling chain 11 around back-pedalling flywheel 10.
