Present known bicycle use spring cushion substantially all is made up of the sub-thread cylindroid helicalcoil compression spring, and when cycle wheel was subjected to the impact on road surface, spring cushion can play buffer function.But when the natural frequency of road excitation frequency and human-bicycle system identical or near the time, resonance phenomenon will take place, at this moment because the sub-thread cylindroid helicalcoil compression spring in the spring cushion does not have damping function, can not effective attenuation vibration, cause serious jolting and influence and drive travelling comfort.In addition, the useful effect of spring cushion is and rationally applies precompression according to bicycler's body weight, the discomfort of sagging or being upspring for the rider is not had when getting on and off, and general spring cushion all has the precompression controlling device.The size of precompression should rationally be regulated according to individual body weight for humans, and precompression is excessive, and vibration damper is inoperative; Precompression is too small, and then the rider just has the discomfort of sagging or being upspring when getting on and off, but the vibration damper that uses at present all can not reach desirable effect.
Summary of the invention
Can not effective attenuation vibrate and the shortcoming that can not correctly apply precompression in order to change existing bicycle spring cushion, the purpose of this utility model provides a kind of have certain damping function, energy effective attenuation vibration, the bicycle use multi-strand spring vibration damper that simultaneously vibration damper is effectively played a role.
Followingly illustrated with reference to 1～5 pair of know-why of the present utility model of accompanying drawing.Bicycle use multi-strand spring vibration damper has last joining end 1, last guide rod 2, adjusting nut 3, spring 4, following guide rod 5, lower stop piece 6, lower link end 7, upper bush 8, lower sleeve 10.Spring 4 is to twine the multi-strand spring that constitutes by central strand and silent partners Spring Steel Wire, and the central strand of multi-strand spring is 1～7 strand, and silent partners is 3～11 strands.Be carved with body weight scale 9 in the outside of lower sleeve 10, this scale calibrates by the relation of precompression with general rider's weight range by test, and the user can be according to individual body weight for humans rotation precompression adjusting nut 3 to body weight scale 9 corresponding scales.Lower sleeve 10 penetrates down guide rod 5, and upper bush 8 penetrates guide rod 2, and last guide rod 2 is threaded, and adjusting nut 3 and last guide rod are spun on an adjusting that is used from precompression.Multi-strand spring 4 penetrates guide rod 2 and following guide rod 5 is positioned at upper bush 8 and lower sleeve 10.The effect of lower stop piece 6 is the supports as lower sleeve 10 and multi-strand spring 4, and lower stop piece 6 passes down guide rod 5 and places lower link end 7 places.According to the stressing conditions of spring, slippage relatively between upper bush 8 and the lower sleeve 10.Going up joining end 1 during use connects with the bicycle rear suspension; Lower link end 7 connects with the bicycle main car frame.When bicycle was subjected to road shocks, rear suspension reached vibration damper with impact force, and the multi-strand spring on the vibration damper is compressed, and absorbed impact energy, made kinetic energy be converted into elastic potential energy; After impact force disappeared, elastic potential energy is converted into kinetic energy again made bicycle produce certain vibration.Under the effect of spring-back force, the conversion meeting of this energy back and forth.In conversion process of energy, the length of spring constantly changes, and makes to produce certain relative movement between the spring silk of multi-strand spring or have relative movement trend, thereby produces frictional force, makes the multi-strand spring vibration damper have certain damping.Because the existence of this damping, the amplitude that bicycle is vibrated is decayed gradually and it is tended to be steady very soon, thereby alleviates the discomfort that vibration band is given the rider.Wherein the big I of the rigidity of multi-strand spring and damping is by the number of share of stock of material, central strand and the silent partners of spring thread, and the different canoe of spring silk changes.
