Abstract
The invention discloses a method for vibration attenuation of an air spring bicycle with an additional air chamber and a bicycle. A bicycle saddle is arranged on a horizontal swinging arm; the horizontal swinging arm is hinged on a front frame, and can be rotated upwards and downwards around a hinge; an air spring is arranged between the horizontal swinging arm and a rear frame so as to close part (as an air chamber) of a steel tube of the rear frame; an air channel is arranged between the air spring and the additional air chamber; according to road condition and the weight of a cyclist, the size of the air channel can be changed by manually rotating a channel adjusting valve core, thereby realizing varied stiffness and varied damping of the air spring, and obtaining an ideal vibration attenuation effect for the cyclist. The vibration attenuation bicycle disclosed by the invention is simple in structure, good in vibration attenuation effect, strong in adaptability to road conditions and loads and suitable for the riding requirements of various road surfaces, and has a more outstanding vibration attenuation performance on unpaved roads.
Description
Technical field
The present invention relates to a kind of bicycle, particularly a kind of air bellow bicycle shock-absorption method and bicycle with auxiliary chamber.
Background technology
Though existing bicycle has multi-form improvement in shape, but for the ground-surface comformability, especially lack great improvement for a long time for the rough ground-surface comformability in rural area, in recent years, the bicycle that some vibration dampings constantly occur, as the patent No. is 92229172.1, name is called Mountain bike and the patent No. is 96202667.0, name is called the vibration damping bicycle, the patent No. is 95217065.5, Dual vibration absorbing bicycle before and after name is called, the patent No. is 93247452.7, name is called the bicycle vibration suspension device, shock absorption device before and after they all are provided with, existing bicycle is done many work aspect the damping, obtaining certain effect.But also all there is certain defective in they: as the patent No. is 92229172.1 patented product, and its rear arm is a single tube, and its bending strength is little, and shelf can not load-bearing thereafter, and preceding shock-damping structure is huge, and weight is big; The patent No. be 93247452.7 product the damping stroke is little thereafter, and be subjected to the restriction of chain; The patent No. is that its shelf load-bearing of product of 95217065.5 is limited, can only singlely ride and sail, and preceding damping is unreasonable, and the path of motion of front axle contradicts with the path of motion of piston rod; The patent No. be 96202667.0 product its back shelf can't be installed, front fork is unreasonable, because of its front wheel spindle not in the forward position of the extended line of steering shaft, turn to dumb, in addition, the rigidity of the shock attenuation unit of these bicycles and damping all are the definite values of determining in the design, can not regulate according to road conditions, cyclist's weight etc.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of air bellow bicycle shock-absorption method and bicycle with auxiliary chamber is provided, this bicycle only need be installed the air bellow of a band auxiliary chamber as damping element, its rigidity and damping adjustable size, it can all carry out effective attenuation to the vibration from front and rear wheel, and the back shelf have enough weight capacities simultaneously.Even run into bigger ditch when travelling, it is very smooth-going that the people can feel.
In order to achieve the above object, the technical solution used in the present invention is:
1. air bellow bicycle shock-absorption method with auxiliary chamber
Adopt the air bellow of band auxiliary chamber to realize bicycle shock-absorption as damping element.
2. air bellow vibration damping bicycle with auxiliary chamber
The air bellow vibration damping bicycle of band auxiliary chamber of the present invention is by front and rear wheel, forward and backward vehicle frame, transversal swinging arm, handlebar, vehicle seat, shelf, the compositions such as air spring assembly of band auxiliary chamber; It is characterized in that: vehicle seat is installed on the transversal swinging arm, transversal swinging arm is hinged on the front vehicle frame, can in vertical plane, rotate up and down, the air bellow of band auxiliary air reservoir is housed between transversal swinging arm and the back vehicle frame, both communicate by the air by-pass passage of an adjustable size, along with the amount of air that charges in air bellow and the auxiliary chamber is different, reach the difference of channel sized between the two, the air bellow of band auxiliary chamber can show different rigidity and damping, thereby can realize best effectiveness in vibration suppression according to road conditions and cyclist's couplings such as body weight best rigidity and damping.
Described auxiliary chamber can be partially enclosed vehicle frame steel pipe, and its volume is 1.5～2 times of air bellow volume.
The invention has the beneficial effects as follows:
Utilize the non-linear rigidity characteristic of air bellow to obtain low natural frequency, thereby can decay the uneven vibration that produces of face more, and can regulate the rigidity and the damping of shock attenuation unit, thereby can realize best effectiveness in vibration suppression according to road conditions and cyclist's body weight etc.
Description of drawings
