The content of the invention
It is high it is an object of the invention to overcome the deficiencies of the prior art and provide rational in infrastructure, easy to assembly, structural strength and A kind of good front wheel of electric bicycle axle mounting structure of braking effect.
The present invention adopts the technical scheme that:
A kind of front wheel of electric bicycle axle mounting structure, including axle sleeve, spoke and wheel rim, the outer rim of axle sleeve are integrally made more Individual spoke, the outboard end integrally connected of all spokes are used for the wheel rim for installing tire, it is characterised in that:The axle sleeve is integrated Structure and through hole is made by one end to the other end, an annular groove is made in the inner edge at the through hole both ends respectively, and two annulars are recessed A bearing is embedded in groove respectively, front axle is rotatablely installed in two bearings, the made shaft shoulder end face in the front axle both sides is pushed up respectively It is pressed on the inner side end of the bearing inner race of homonymy, the front axle outer rim engaging sleeve on the outside of each bearing fills a limit base, and this is spacing Seat is crimped on towards the end face of bearing in the end face outside of homonymy bearing inner race, and each limit base is pacified with homonymy front axle outboard end The bottom of fastening setting-in front fork between the fixed seat of dress.
Moreover, each limit base each blocks side and stretched out close to side is blocked with integrally being made in the outer rim of side bearing To the outer ring of same side bearing, inner edge retention gap of the outer rim on side with axle sleeve with side end is each blocked.
Moreover, the fixed seat is towards making shrinkage pool on the end face of preceding shaft end, before the shrinkage pool engaging sleeve is mounted in homonymy Shaft end and the two sides that top pressure front fork bottom is distinguished with limit base, a peace is made in end face of the fixed seat away from preceding shaft end Hole is filled, the end engagement of the fixing bolt penetrated in the mounting hole is connected to the screw thread elongated hole made in preceding shaft end and will fixed Seat fastening is crimped on preceding shaft end.
Moreover, brake disc is installed on a side end face of the axle sleeve.
The advantages and positive effects of the present invention are:
In the present invention, axle sleeve is structure as a whole, and without using end cap, the both ends of axle sleeve are embedded in a bearing, front axle respectively The inner side end of bearing inner race is blocked in the shaft shoulder end face that both sides are made, and the outside of limit base top pressure bearing inner race is set with the outside of front axle End face, thus front axle, bearing are fixed in axle sleeve, active force is distributed on whole spoke and wheel rim by bearing, ensures it The stabilization and safety of rotation, before the front axle outer rim installation between the fixed seat of two end installations of front axle and the limit base of homonymy Fixed seat is simultaneously locked by fixing bolt in the bottom of fork, and said structure is very simple, very convenient when installing and safeguarding, A brake disc is installed in the side end face of axle sleeve one, and the area of the brake disc is changeable, and supporting brake block can also be according to actual feelings Condition determines that fit system is very flexible, and the heat that brake is sent rapidly is dispersed into environment, and the heat fade of brake is small, The stabilization and safety of driving are ensure that, in summary, it is that one kind is easy to use, easy to assembly, structural strength is high and brake effect The good structure of fruit.
