Abstract

The utility model relates to a bicycle balance device which is arranged at a bicycle frame to keep stabilization when the bicycle runs and solves the problem that the bicycle has poor stability when the bicycle is run slowly or paused. The bicycle balance device comprises balance wheels, balance arms, stop raise components, stop fall components and a brake disk. When the back brake of the bicycle is operated, the balance wheels are stressed close to the ground. When the bicycle runs normally, the balance wheels are raised. The utility model is an ideal bicycle balance device which is used in the bicycle.

Description

Bicycle balance device

The utility model belongs to be attached on the cycle frame and keeps stable device by bike, particularly a kind of bicycle balancing device.

The bicycle of present common use is two wheels, park is to support by station, both sides pin or station, limit pin, but two-wheeled cycle is its less stable when slowly travelling, when particularly on certain section crowded highway, riding, the traffic accident that overturning is thrusted into takes place easily, if meet emergency situation (as hollow) but during sudden stop also the able person move backward and turn over, bring some danger, if change two-wheeled cycle into three-wheel vehicle, though its stability better, but it is light also just to have lost two-wheeled cycle, flexible characteristic has increased the friction drag of vehicle ', makes the rider arduous painstaking.In order to solve the stability of two-wheeled cycle, people have also found out a lot of ways, as Chinese patent disclosed " patent No.: 87205167; be used for the stabilizing device of bicycle " though possessed and need stop to have two foot wheels to stand immediately, can regain the advantage of foot wheel when riding, but complex structure, and the foot wheel is landed by pinching brake all the time, thereby the defective of self is arranged.

The purpose of this utility model provide a kind of be used for bicycle slowly travel or suspend, particularly during emergency brake, the bicycle balancing device that bicycle can held stationary.

The utility model is finished with following mode, the bicycle balancing device, it is made up of balance wheel and equilibrium arm etc., balance wheel is contained on the equilibrium arm, equilibrium arm is installed on the supporting base with bolster and axle sleeve through Die Scheibenbremse, supporting base is installed on the bicycle back rest, on supporting base, be equipped with contact with Die Scheibenbremse only rise part and falling stop part, only rise part through promoting attaching parts and promoting foot-operated the connection, lifting member connects equilibrium arm, and the falling stop part is connected with bicycle rear brake pull bar through the landing attaching parts.Only rising part is sliding pawl contact or contact of commentaries on classics pawl or wipe contact with falling stop part and contacting of Die Scheibenbremse.
