Problems solved by technology

However, when this bicycle is reversing and the wheel is reversed together with the ratchet wheel, due to the engagement of the inner ratchet and the ratchet, the driven sprocket is driven to reverse, resulting in driving mechanisms such as drive chains, driving sprockets, and pedals. reverse
Therefore, there is a problem that the bicycle using this overrunning clutch cannot reverse

Embodiment 1

[0024] A reciprocating pedal type double-flying bicycle of the present invention is shown in the accompanying drawings. It is composed of a bicycle frame 1, a saddle 2, a steering handle 3, a brake and a brake handle 4, a front wheel 5, a rear wheel 6 and a driving mechanism etc. of a bicycle of a general structure. The driving mechanism is composed of pedals, driving wheels, falling wheels, overrunning clutches, transmission chains and the like.

[0025] For the pedals mentioned above, see figure 1 , 3, the left pedal 7 and the right pedal 8 of the crank formula of common structure are arranged. drive wheel above, see figure 1 , 3, there is the left drive wheel 9 and the right drive wheel 10 that are respectively connected with the left pedal and the right pedal to be coaxial. Left pedal 7 and left driving wheel 9 usefulness bearings are installed on the left end of bicycle central axis 11, and right pedal 8 and right driving wheel 10 usefulness bearings are installed on t...

Abstract

A reciprocating pedal type dual-flywheel bicycle able to run backward is composed of frame, saddle, handlebar, front and back wheels, left and right pedals, left and right overriding clutches, eccentrical and sectoiral left and right drive flywheels, and drive chain which is engaged sequentially with left drive flywheel, left overriding clutch, inertial wheel on frame, right overriding clutch and right drive flywheel. Its advantages are high speed and reliability, and long service life.

Description

technical field [0001] The invention relates to a bicycle in transportation, especially a human-powered bicycle driven by reciprocating pedals and capable of reversing. Background technique [0002] The existing bicycle consists of a vehicle frame, a saddle, a steering handlebar, a front wheel and a rear wheel, a reciprocating and rotating rod-shaped left and right pedal connected to the vehicle frame, and an overrunning clutch type fixedly mounted on the left and right sides of the rear wheel axle. There are left and right drive wheels with back-moving springs, respectively connect the left and right drive wheels of the left and right pedals with two nylon ropes or flat belt-type transmission belts, one end of the transmission belt is connected with the pedals, and the other end is wound on the drive wheels. When the left pedal is stepped down with the left foot, the left driving wheel and the rear wheel are pulled to rotate through the transmission belt to drive the bicycl...
