Abstract

The utility model provides a gearing device for motorcycle or bicycle, comprising a driving shaft connected with an engine, an electric motor or a treadle device, and a driven shaft driven by the driving shaft. The driving shaft is connected with a direction-changing driving gear box which can change the direction within 90 degrees, which makes that the output shaft direction of the gear box is uniformed with the longitudinal direction of a vehicle body. The output shaft of the driving gear box is connected with a driving gearing shaft which is connected with a universal coupling. The universal coupling is connected with a driven gearing shaft. The power take-off end of the driven gearing shaft is connected with a direction-changing driven gear box which can change the direction within 90 degrees. The driven gear box is connected with a rear driving wheel, which makes that the rear driving wheel can rotate following with the driving shaft. The traditional chain gearing mechanism is replaced by the gearing mechanism composed by the gear box and the universal coupling. Thereby, compared with the traditional products driven by chains, the gearing device for motorcycle or bicycle of the utility model has the advantages of stable moving, non-perishable wear, cleanness and easy maintenance.

Description

The driving device of motor bike or bicycle

Technical field

The utility model relates to the driving device of motor bike or bicycle.

Background technology

Tradition motor bike or bicycle have the stable transmission advantage by former and later two sprocket wheels and chain gear, and shortcoming is that chain falls easily, chain cover weares and teares easily, greasy dirt big, the inconvenience maintenance.

The transmission device of forming by gear break-in, speed-changing mechanism and transmission shaft replaces traditional sprocket wheel and chain gear to be undoubtedly a kind of good idea.Problem is that motor bike or bicycle structure are simple, the road conditions complexity of walking, not steady, and therefore, the transmission device that simply utilizes gear break-in, speed-changing mechanism and transmission shaft to form replaces traditional sprocket wheel and chain gear to be undoubtedly a kind of infeasible scheme.

Summary of the invention

Task of the present utility model overcomes the defective of prior art, designs a kind of smooth running, not easy to wear, cleaning, the motor bike of easy care or the driving device of bicycle.

Task of the present utility model can be achieved by the following technical programs:

The driving device of motor bike or bicycle, comprise the imput shaft that links with driving engine, electrical motor or foot pedal apparatus, be subjected to initiatively shaft drying driven shaft, it is characterized in that described imput shaft links to each other with one 90 ° of break-in drive gear carriers, the output shaft that makes gear case to the vertical consistency of vehicle body; Be connected with an initiative drive shaft with the output shaft of drive gear carrier, be connected with a universal coupling with initiative drive shaft, be connected with a driven transmission shaft with universal coupling, the clutch end of driven transmission shaft links to each other with one 90 ° of break-in driven tooth roller boxs, the driven tooth roller box links to each other with rear drive sprocket, makes it to rotate with imput shaft.

Described universal coupling comprises a criss-cross coupled axle-pin and a pair of capping that is fixed in it, correspondingly with coupled axle-pin on the capping edge has two pairs of semicircle orifices the pin of coupled axle-pin is held outside the extended capping; Coupled axle-pin, two capping threes are one by bolt combination; Universal coupling also comprises a pair of " U " shape adaptor union, but two wall is provided with the hole of socket pin end, and the end of two " U " shape adaptor union then links to each other with driven transmission shaft with described initiative drive shaft respectively.

The utility model is owing to adopted such scheme, the transmission device that constitutes with gear case and versatile spindle replaces traditional chain drive, thereby makes the advantage that has smooth running, not easy to wear, cleaning, easy care with the utility model as the motor bike of driving device or bicycle compared to prior art.

The specific embodiment

The driving device of a kind of motor bike or bicycle comprises the imput shaft that links with driving engine, electrical motor or foot pedal apparatus 15, is subjected to initiatively shaft drying driven shaft.Imput shaft links to each other with one 90 ° of break-in drive gear carriers 1, the output shaft that makes gear case 1 to the vertical consistency of vehicle body; Be connected with an initiative drive shaft 2 with the output shaft of drive gear carrier 1, be connected with a universal coupling 3 with initiative drive shaft 2, be connected with a driven transmission shaft 4 with universal coupling 3, the clutch end of driven transmission shaft 4 links to each other with one 90 ° of break-in driven tooth roller boxs 5, driven tooth roller box 5 links to each other with rear drive sprocket 6, makes it and can rotate with imput shaft.

Universal coupling 3 comprises a criss-cross coupled axle-pin 7 and a pair of capping 8 that is fixed in it, correspondingly with coupled axle-pin 7 on capping 8 edges has two pairs of semicircle orifices 9 pin of coupled axle-pin 7 is held outside the 10 extended cappings 8; Coupled axle-pin 7, two cappings, 8 threes are combined into one by 4 bolts 11.Universal coupling 3 also comprises a pair of " U " shape adaptor union 12, but two wall is provided with the hole 13 of socket pin end 10, and adaptor union 12 is connected by snap ring or pin 14 with pin end 10.The end of two " U " shape adaptor union 12, link to each other with driven transmission shaft 4 with initiative drive shaft 2 respectively, no matter how rotate at the angle of inclination in motion process for initiative drive shaft 2 or driven transmission shaft 4, driven transmission shaft 4 or initiative drive shaft 2 all can rotate thereupon, and then driven tooth roller box 5 and rear drive sprocket 6 are rotated, order about motor bike or bicycle walking.

Drive gear carrier 1 and driven tooth roller box 5 can carry out 90 ° of break-ins by the bevel gear pair, and other gear cluster carries out speed change, because belong to general technology general knowledge, just avoid giving having described in detail at this.
