Abstract

A foldable chainless damping bicycle is disclosed. A front wheel 1, a rear wheel 8, a medial axis 5 are arranged on a bicycle frame 3, the medial axis 5 is provided with a ratchet wheel 17 which is sleeved with a big bevel gear 11. When rotating, the medial axis 5 drives the ratchet wheel 17 and the big bevel gear 11 sleeved on the outside diameter at the meantime to rotate. The rear wheel 8 is driven to rotate through the rotation of a small bevel gear 12, a small bevel gear 14 and a small bevel gear 15 to push the bicycle to move. A big circinal damping torsion spring 10 is arranged between the riser end of the bicycle frame 3 and a rear bottom fork 7. When the bicycle is ridden, the big circinal torsion spring plays the role of damping. The bicycle has not only a simple structure, but also a more comfortable, smooth and convenient damping effect, and can be folded through opening a folder 16.

Description

A kind of collapsible no chain damping bicycle
The utility model relates to a kind of collapsible no chain damping bicycle.
General-duty does not have the chain damping bicycle now, and its running part is comparatively complicated, will adorn a large diameter bevel gear on the axis, adorns ratchet-gear wheel, bevel gear and the special-purpose axle sleeve of a special use on the rear axle.Its shock absorbing part mostly adopts stage clip or extension spring.Shortcoming is that structure is complicated, and elasticity is not soft.
The purpose of this utility model provides a kind of simple in structure, and vehicle body is collapsible, and its transmission and shock absorbing part more reasonably do not have the chain damping bicycle.
The purpose of this utility model is achieved in that
Be fixed with front axle, hinge, axis, rear axle on the vehicle frame, front axle is fixed with front-wheel, be fixed with trailing wheel on the rear axle, front and back wheel all can be rotated on the axle of being fixed, front-wheel also serves as wheel flutter, hinge is connected with vehicle frame and back chain stay, between back chain stay tail end and seat tube the torque spring that the great circle damping is used is installed, and the two ends of its torque spring are separately fixed on seat tube and the back chain stay; A big umbrella shape ratchet-gear wheel that ratchet-gear wheel and large bevel gear is made as one has been installed on the axis.
Brought following advantage owing to done above improvement, owing to be that traditional rear axle ratchet-gear wheel is changed on the large bevel gear that moves on on the axis, and be made as one, made full use of the volume of large bevel gear, make the large bevel gear of same volume have two kinds of functions, and rear axle has been owing to removed ratchet-gear wheel, can make littler that the bevel gear volume does, and axle sleeve can directly use gauge member, make structure more simple, improve transmitting ratio, and fallen end weight, saved steel.
The damping torque spring of great circle is installed between seat tube end and back chain stay tail end, and when the people is sitting in when riding on the bicycle, under the effect of great circle damping torque spring, vehicle frame is center of circle motion with the hinge with the back chain stay, and plays cushioning effect.Because what adopt is the torque spring of great circle damping, so when riding this car, the sensation damping effect is soft more comfortable, light.
Further introduce the utility model below by accompanying drawing
Fig. 1 is an outside drawing of the present utility model.
Fig. 2 is a big umbrella shape ratchet-gear wheel on the axis, bevel gear type of drive birds-eye view to the rear axle.
From Fig. 1, can see, front-wheel 1 is installed on the front axle 2, trailing wheel 8 is installed on the rear axle 9, front axle 2 rear axles 9 are installed on vehicle frame 3 and the back chain stay 7, and vehicle frame 3 is connected with back chain stay 7 by hinge 4, and the two ends of great circle damping torque spring 10 are separately fixed at seat tube and chain stay rear end, back, folder 16 is installed in the middle of the vehicle frame 3, this shows that when the people is sitting on the bicycle, great circle damping torque spring 10 will play good cushioning effect.
From Fig. 2, can see, ratchet 17 fixes with axis 5, ratchet is with gamp wheel 11 outward, axis 5 two ends are equipped with crank 6, big umbrella shape ratchet-gear wheel 11 is meshed with a bevel pinion 12 again, and bevel pinion 12 is mounted in the front end of transmission shaft 13, and the rear end of transmission shaft 13 also is equipped with bevel pinion 14, transmission shaft 13 is mounted in the back in the right chain stay pipe, and bevel pinion 14 is meshed with bevel pinion 15 on being installed in rear axle 9.When stepping crank 6 when axis 5 is rotated, gamp ratchet-gear wheel 11 rotates thereupon, drives bevel pinion 12 rotations simultaneously, bevel pinion 12 rotates bevel pinion 14, drive the bevel pinion 15 that is meshed with it simultaneously and rotate, thereby trailing wheel 8 is rotated, bicycle is exercised forward.
Vehicle frame 3 middle parts are equipped with folder 16, when the need folding bicycle, open folder 16 tight cage knobs and can make vehicle frame folding, make front and back wheel and are close together, and are easy to carry.
