Abstract

The utility model relates to the bicycle technology, particularly a forward/backward force increasing bicycle which comprises a bicycle frame, a front wheel, a back wheel, a middle axle with screw threads which is arranged on the lower part of the bicycle frame, a middle axle gear which is arranged on the middle axle, a front gear which is meshed with the middle axle gear, a front gear of which the front end is arranged on a transmission shaft, a back gear which is arranged on the back end of the transmission shaft, and a gear which is arranged on an axle casing of the back wheel and meshed with the back gear, wherein the middle axle of the forward/backward force increasing bicycle can drive the forward/backward force increasing bicycle to advance by veering, and can also drive the forward/backward force increasing bicycle to advance by reversal. Thereby, the utility model can mitigate fatigue for people of riding bicycles for a long distance journey, and body-building people by riding bicycles can obtain ideal body-building effect.

Description

Along contrary Bicycl with booster

The utility model belongs to the technical field of bicycle.

The bicycle of our usefulness now, and though be single-wheel, two-wheel or three-wheel all be unidirectional afterburning the driving, promptly the people steps stretcher when rotating at forward, the wheel of bicycle is stressed to rotate forward, and when oppositely changeing stretcher, wheel does not then stress, and can not drive wheels travel forward, though unidirectional drive can make bicycle travel forward, but when long-term travel, the people is tired easily, and when bicycle during as fitness tool, the more position that can not take exercises, the perfect sportsing body-building effect of out of reach.

The purpose of this utility model can both drive the proal bicycle of bicycle when providing a kind of clockwise reinforcing and reversing reinforcing.

This along comprising vehicle frame against Bicycl with booster, be contained in the front fork of vehicle frame front end, be contained in the handlebar of front fork upper end, be contained in the front-wheel of front fork lower end, be contained in the saddle of upper end behind the vehicle frame, be contained in the trailing wheel of Vee formation frame posterior end, be fixed on the ratchet on the hind axle skin, be contained in the buting iron of the spider lower end of vehicle frame, comprise that also activity is contained in the axis on the buting iron, and axis is provided with screw thread, be contained in the middle shaft gear on the axis, can with the front gear of axis gear mesh, be fixed on the front gear at the chain stay Inner Front End, the transmission shaft of chain stay rear end is stretched out in the rear end, be contained in the backgear of transmission shaft rear end, be fixed on the ratchet and the backgear gears in mesh.

Owing on axis, be provided with screw thread, be contained on the axis and middle shaft gear cooperates with axis, when the people rotates by foot-operated drive axis, then axis is shifted to left side or right side with middle shaft gear, then the both sides tooth of middle shaft gear meshes with front gear respectively, the drive front gear rotates, no matter thereby realize that clockwise direction steps foot-operated or anticlockwise direction steps foot-operated, can both drive bicycle travels forward, make bicyclist's indefatigability, and it during as body-building apparatus, the more position that can take exercises reaches perfect train on.

Accompanying drawing shows embodiment of the present utility model, wherein:

Figure 1 shows that along contrary Bicycl with booster block diagram;

Figure 2 shows that semi-sictional view enlarged drawing along A-A line shown in Figure 1;

Figure 3 shows that along contrary Bicycl with booster transmission structures scheme drawing.

Suitable contrary Bicycl with booster as shown in the figure, comprise vehicle frame 1, be contained in the front fork 2 of vehicle frame 1 front end, be contained in the handlebar 3 of front fork 2 upper ends, be contained in the front-wheel 4 of front fork 2 lower ends, be contained in the saddle 5 of upper end, vehicle frame 1 back, be contained in the trailing wheel 6 of Vee formation frame posterior end, be fixed on the ratchet 15 of axle on the skin of trailing wheel 6, be contained in two buting iron 7 of the both sides, spider lower end of vehicle frame 1, activity is contained in the axis 8 on two buting iron 7, and axis 8 is provided with screw thread 9, be contained in the middle shaft gear 10 that cooperates with screw thread 9 on the axis 8, middle shaft gear 10 is round H shape.Can with the left and right side tooth ingear front gear 11 of the middle shaft gear 10 of H shape, and front gear 11 is a bevel gear.At the transmission shaft 12 that right side chain stay Inner Front End is fixed on the front gear 11, the chain stay rear end is stretched out in the rear end, be contained in the backgear 13 of transmission shaft 12 rear ends, backgear 13 is a bevel gear.Be fixed on the ratchet 15 and backgear 13 gears in meshs 14, and gear 14 is a bevel gear.

Owing on the axis of bicycle, screw thread is arranged, then when rotating middle shaft forward, the screw thread fit on the screw thread on the axis and the middle shaft gear, shaft gear is shifted to the axis left side in making, and the right side tooth of shaft gear and front gear mesh in the H shape, and the driving bicycle travels forward; When the backwards rotation axis, middle shaft gear is shifted to the axis right side, and the left side tooth of middle shaft gear and front gear engagement still travel forward thereby also drive bicycle.Thereby make the people feel that neither long-term travel is too tired, simultaneously if be used to take exercises, then the more position of health obtains taking exercise, and reaches good body-building effect.
