Abstract
The utility model relates to a back elasticity shock absorber for bicycles, which is the back elasticity shock absorber which is suitable for the bicycles, small-size motorcycles, power-assisted vehicles, and manpower vehicles. Defects, such as dead point occurrence, great energy loss, easy abrasion, short service life, left and right swing, etc. when a barrel type shock absorber works are overcome by the back elasticity shock absorber for bicycles. Two barrel type shock absorbers can be replaced by one set of back elasticity shock absorber for bicycles. The back elasticity shock absorber for bicycles has the advantages of simple structure, low cost, and favorable performance. The shock absorber can work in non-linear regions, and can work in wider working loads without the dead points. The back elasticity shock absorber for bicycles is composed of a connecting rack, a main spring plate group, an auxiliary spring plate group, a back oblique fork, a back flat fork, and a main oblique beam, and is mainly used for the shock absorbers of the bicycles, the small-size motorcycles, the power-assisted vehicles, and the manpower vehicles.
Description
The utility model relates to elastic force shock absorbing apparatus behind a kind of adaptation bicycle, motor scooter, boosted vehicle and the rickshaw.
At present, back shock absorbing apparatus such as known bicycle, boosted vehicle mostly adopts two cartridge type shock absorbing apparatus.The cartridge type shock absorbing apparatus generally is divided into coil spring, hydraulic damping, and comparatively Fu Za cartridge type shock absorbing apparatus is to adopt spiral to add hydraulic pressure to mix formation.With the simplest cartridge type coil spring shock absorbing apparatus is example: it is by last lower adaptor, up and down formations such as sleeve, coil spring, guide rod, guide rod plug.Two cartridge type shock absorbing apparatus branch left-right symmetric of general employing are installed and used on bicycle or boosted vehicle.The cartridge type shock absorbing apparatus in when work since up and down sleeve pipe, guide rod, guide rod plug exist friction, loss of energy is bigger, allows the people ride sensation especially for bicycle and sends out heavy, is clamminess, consumes especially power, row is ridden uncomfortable, efficient is reduced greatly, and each parts weares and teares easily, and the life-span is low.Since about respectively adopt a cartridge type shock absorbing apparatus, the wigwag motion disadvantage appears at work easily, make bad stability, cost is also higher relatively.The general load range of common cartridge type shock absorbing apparatus is narrower, can not bear load in a big way, when load is big, or prominent when meeting concavo-convex road surface, occurs " exposing the false " phenomenon easily, promptly is compressed to the end dead point to occur, has lost incabloc function.
The purpose of this utility model provides elastic force shock absorbing apparatus behind a kind of bicycle, and it is simple in structure, and the friction loss energy is minimum, the efficient height, the acomia heavy sensation that is clamminess, it is little to wear and tear, life-span is long, has overcome the wiggly disadvantage that the cartridge type shock absorbing apparatus brings, good stability.The elastic force shock absorbing apparatus can replace two cartridge type shock absorbing apparatus behind the one cover bicycle, and is simple in structure, cost is low.Because the elastic force shock absorbing apparatus can be operated in nonlinear area behind the bicycle, can in the working load of broad, work and do not have the dead point.
The elastic force shock absorbing apparatus was made of main cant beam, middle connecting shaft, back chain stay, the fork that retreads, main spring plank, auxiliary spring plate, link span after the purpose of this utility model was achieved in that a kind of bicycle, and it is characterized in that: main spring plank and auxiliary spring plate are superimposed.Main spring plank and auxiliary spring plate are stepped; one end is connected with main cant beam by link span; the other end is penetrated the main brass that is located on the main spring plank and the fork that retreads and joins by the stub bolt; main spring plank and auxiliary spring sleeve-board have safety dog, protection hoop, safety dog to be provided with the punching rivet; the protection hoop is provided with and protects the hoop rivet, and main spring plank and auxiliary spring plate are entangled by oversheath.
Its principle of work is such: equaling when vehicle seat is manned increases a load FZ to vehicle seat, at this moment FZ is delivered to middle connecting shaft by main cant beam, middle connecting shaft, bottom bracket axle constitutes a back movable up and down chain stay with the back chain stay, the other end of back chain stay is connected with wheel, wheel contacts with ground and forms an antagonistic force, link to each other with an end of the fork that retreads by the axle in flakes on the back stay, the other end of pitching that retreads joins with stub bolt and main spring plank, link span on the other end of main spring plank and the main cant beam fixes, middle connecting shaft, in flakes the axle, the stub bolt has constituted mobilizable three fulcrums, FZ conducts power on main spring plank by three fulcrums.Main spring plank has produced the power of a K/UP, and the auxiliary spring plate is crooked and crooked with main spring plank, and this moment, main spring plank auxiliary spring plate was curved.When FZ was increased to some values, main spring plank, auxiliary spring plate had entered nonlinear state, and the motion amplitude increase that promptly increases FZ master's spring plank, auxiliary spring plate again is very little.Another kind of situation is, when FZ is constant, wheel is when concavo-convex road traveling, the FZ that is equivalent to a fitfull variation is in fluctuation, because the spring plank assembly can be operated in nonlinear area, even running into the impulsive force that brings on unexpected bigger concavo-convex road surface still can work in certain scope, and problems such as dead point can not appear, suitable rough road traveling, in order to make main spring plank safe and reliable, the spy is provided with safety dog, and safety dog is that main spring plank and auxiliary spring plate are passed main spring plank by the punching rivet, the auxiliary spring plate, rivet together, improved the reliability of work.The effect of protection hoop is similar to the effect of safety dog, and the protection hoop is enclosed within the safety dog back, by protecting the hoop rivet, being riveted on the auxiliary spring plate.Another function of safety dog protection hoop is that main spring plank, auxiliary spring plate are combined with each other; when the main cant beam of the bicycle of moving; because having certain quality to exist, trailing wheel produces a downward pulling force; if there is not the existence of safety dog protection hoop; main spring plank and auxiliary spring plate will scatter; safety dog, protection hoop are combined with each other main spring plank, auxiliary spring plate, play with the purpose of safety guard-safeguard.Be with main brass in the ring of main spring plank, link to each other with the fork that retreads by the stub bolt.The material requirements that main brass is selected for use is very wear-resisting, and precision is very high, make the main spring plank and the fork work of retreading become axial work, and it is minimum to wear and tear, high efficiency.Overcome and adopted two cartridge type shock absorbing apparatus to bring wiggly disadvantage, design is simplified.
Owing to adopted abovementioned technology, simplified the design of shock absorbing apparatus, reduced cost, improved work efficiency, do not had the dead point during work, overcome telescopic type damper and brought wiggly disadvantage, and good stability, wearing and tearing are little, reliability is high, long service life, helps penetration and promotion.
