Abstract

The utility model relates to a bicycle driving device. A novel bicycle driving device comprises pedals, a gear, a rack, a guiding rail, a driving chain, a wrap-round device and a driving flywheel; the pedals are connected with the rack, the rack is mounted on the guiding rail and can slide vertically in a linear mode, the gear is connected on the driving flywheel, and the chain is wound on the driving flywheel. When a cyclist treads the pedals, the rack slides vertically on the guiding rail, the rack and the gear drive the driving flywheel to rotate in a circumferential mode by means of correct meshing movement, and therefore forward movement of a bicycle is achieved; the wrap-round device drives the rack to wrap around the guiding rail for restoration, and the cyclist treads the pedals in a left-and-right alternate mode to drive the bicycle to continue to move forward at a constant speed; compared with a traditional bicycle driving device, the novel bicycle driving device enables vertically reciprocal rectilinear motion of the pedals to be converted into uniform circular motion of bicycle wheels, and more accords with the motor function of a human body, so that the cyclist ride the bicycle more conveniently and fast and labor is saved. The novel bicycle driving device is more stable in structure, higher in converting efficiency, capable of effectively avoiding disadvantages, such as nonuniform application of force and occurrence of dead spots, of the traditional bicycle driving device in a riding process, and the novel bicycle driving device can be widely used as a manpower driving device on vehicles, vessels and the like.

Description

A kind of propulsion means of bicycle

Technical field

The present invention relates to the Manpower drivers such as a kind of car, ship, particularly a kind of propulsion means of bicycle.

Background technology

Driving function is a radical function of bicycle, at present domestic bicycle drives and mostly is greatly axle crank sprocket device, by crank band movable sprocket, the rotation of drive trailing wheel, and then realize the forward movement of bicycle, there is dead center position in discontinuity in mechanism kinematic, need to could pass through by inertia; And real work efficient is not high.

Summary of the invention

The utility model provides a kind of propulsion means of bicycle, can with the people trample up and down the uniform circular motion that the stretcher straight reciprocating motion converts wheel to, structure is more stable, working process is without the dead point, work efficiency is higher, make drive more steadily laborsaving, comfortable convenient.

For achieving the above object, the utility model provides a kind of propulsion means of bicycle, this device comprises: stretcher, gear, tooth bar, wraparound device, driving flywheel, driving chain, it is characterized in that A tooth bar, B tooth bar are connected on guiding rail, and can move by the up and down line sliding; A tooth bar, B tooth bar correspondence are fixed on A stretcher, B stretcher, and by respectively with A gear, B gear gear motion, drive to drive flywheel and rotate, drive vehicle and move ahead; The wraparound device connects A tooth bar, B tooth bar, is wrapped on vehicle frame, alternately draws A stretcher, B stretcher reply initial position.

Advantage of the present utility model

The utility model bicycle driving device is than the advantage of standard bicycle actuating device: this device adopts alternatively up and down to trample the motion of foot mode, and motion process moment is in maxim and stressed uniformity all the time; And this features simple structure, mode of operation is steady, and is higher than traditional crank chain sprocket driving device work efficiency, simultaneously effectively avoids driving the inhomogeneous and dead center position of the application of force, makes to drive more comfortablely, convenient, and hill climbing ability is stronger.

Description of drawings

Accompanying drawing is the utility model structural representation.

In figure: 1,The A stretcher, 2,The A gear, 3, the A tooth bar, 4, guiding rail, 5,The wraparound device, 6,The B tooth bar, 7,The trailing wheel small flywheel, 8,Drive flywheel, 9,Driving chain, 10,The B gear, 11,The B stretcher.

The specific embodiment

As shown in Figure 1, A tooth bar (3), B tooth bar (6) correspondence are fixed on A stretcher (1), B stretcher (11), and respectively with A gear (2), B gear (10) correct engagement, drive to drive the flywheel rotation, drive vehicle and move ahead; Alternately draw A stretcher (1), B stretcher (11) reply initial position.

A stretcher 1, B stretcher 11 are articulated and connected with A tooth bar 2, B tooth bar 6 respectively, and corresponding the horizontally slipping with guiding rail 4 of A tooth bar 2, B tooth bar 6 is connected, can be flexibly straight-line motion up and down, guiding rail 4 is fixed on vehicle frame; A tooth bar 2, B tooth bar 6 by respectively with A gear 2, B gear 10 gear motions, drive and drive flywheel 8 and rotate; Wraparound device 5 connects A tooth bar 3, B tooth bar 6, is wrapped on vehicle frame.When A stretcher 1 is descending, corresponding drive A tooth bar 3 is made downglide motion on guiding rail 4, move by rack and pinion engagement, driving flywheel 8 rotates, drive 7 rotations of trailing wheel small flywheel by being wrapped in the driving chain 9 that drives on flywheel 8, drive vehicle and move ahead, simultaneously, wraparound device 5 is tightened up stored energy, drives B stretcher 11 up; When coming downwards to terminal point, the A stretcher begins to return when capable, trample B stretcher 11 descending, wraparound device 5 is relaxed and releases energy, drive A tooth bar 3 upward sliding on guiding rail 4, reply initial position, trample footboard drives by straight line up and down reciprocatingly, realize driving flywheel 8 and rotates continuously, the driving vehicle at the uniform velocity moves ahead.

This embodiment is trampled the footboard drives mode up and down owing to adopting, and more meets the human motion function, integrate more scientificly ride instead of walk, leisure, body-building function, increase and drive enjoyment; Adopt pinion and rack, stable than the crank and chain-wheel driving device structure of standard bicycle, work efficiency is higher, has promotional value preferably, can be widely used in the Manpower drivers such as car and boat.
