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.
