Abstract
The utility model relates to a brake drum, its characterized in that: including axle sleeve, wheel hub and brake disc, wheel hub locates the flange of axle sleeve one end, the brake disc is located the flange of the axle sleeve other end, wheel hub last with a plurality of bolts are installed for centre of a circle circumference equipartition in the center of axle sleeve, be equipped with on the brake disc with the through -hole of bolt one -to -one coaxial line, axle sleeve, wheel hub and brake disc formula as an organic whole structure, the inboard of axle sleeve is equipped with the axial keyway. Brake drum compares with traditional brake drum, small, light in weight, and low in manufacturing cost requires to hang down to installation space, the installation of being convenient for.
Description
Technical field
This utility model belongs to body fittings technical field, more particularly to a kind of tricycle brake rim.
Background technology
Brake rim is a kind of ironcasting for being shaped like tambourine, and it is fixed and rotated at the same speed with tire.With oil during brake
Pressure promotes brake shoes contact brake rim inner edge, suppresses the rotation of tire to reach brake by the frictional force of contact generation
Purpose.
The structure of existing brake rim includes rousing body, and one end of the bulging body is provided with set hole, the set hole and the external side face of drum
Between be annulus end face, annulus end face is provided with the bolt of circumference uniform distribution, and the other end of drum body is provided with brake disc.Said structure
Brake rim is constructed for integral type cast iron, and volume and weight is big, high to requirements of installation space, and manufacturing cost is high.
The content of the invention
This utility model aims to solve the problem that the technical problem that brake rim volume weight is big, installation requirement is high in prior art and carries
It is little for a kind of volume and weight, it is easily installed, the brake rim of low cost of manufacture.
This utility model is adopted the technical scheme that by solving technical problem present in known technology：A kind of brake
Drum, it is characterised in that：Including axle sleeve, wheel hub and brake disc；The wheel hub is provided at the flange of described axle sleeve one end, the brake
Disk is provided at the flange of the axle sleeve other end, if being provided with by center of circle circumference uniform distribution of the center of the axle sleeve on the wheel hub
Bolt stem, the brake disc are provided with the through hole for corresponding coaxial line with the bolt, and the axle sleeve, wheel hub and brake disc are
One-piece construction, is provided with axial keyway on the inside of the axle sleeve.
This utility model can also adopt following technical measures：
The axle sleeve, wheel hub and brake disc are spheroidal graphite cast-iron.
This utility model has the advantages and positive effects that：
, compared with conventional brake drum, small volume, lightweight, low cost of manufacture, to installing for brake rim described in the utility model
Space requirement is low, is easily installed.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the side view of Fig. 1.
In figure：1st, axle sleeve；2nd, wheel hub；3rd, brake disc；4th, bolt；5th, through hole.
Specific embodiment
For the content of the invention of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and is coordinated
Accompanying drawing describes in detail as follows：
Fig. 1 and Fig. 2 is referred to, a kind of brake rim, including axle sleeve 1, wheel hub 2 and brake disc 3.The wheel hub 2 is provided at institute
The flange of 1 one end of axle sleeve is stated, the brake disc 3 is provided at the flange of 1 other end of the axle sleeve.As known to mechanical field personnel,
Flange is the torus for protruding axle sleeve outer peripheral face.
If being provided with bolt stem 4 by center of circle circumference uniform distribution of the center of the axle sleeve 1 on the wheel hub 2, bolt 4 is used for will
Wheel is with the wheel hub 2 conjunction.The brake disc 3 is provided with the through hole 5 for corresponding coaxial line with the bolt, this through hole 5
Be provided for process through hole on the wheel hub 2, the bolt 4 is installed on the through hole of the wheel hub 2.The axle sleeve 1, wheel
Hub 2 and brake disc 3 are constructed for integral type, and the inner side of the axle sleeve 1 is provided with axial keyway.In the present embodiment, axle sleeve 1 is matched somebody with somebody by key
It is mounted on the axletree of tricycle.The axle sleeve 1, wheel hub 2 and brake disc 3 are spheroidal graphite cast-iron.
Another way, the through hole 5 run through through hole 5, so make this brake rim near the axle sleeve 1, the bolt 4
Bulk strength is higher.
The foregoing is only preferred embodiments of the present utility model, however it is not limited to this utility model, it is clear that the skill of this area
Art personnel can carry out various changes and modification without deviating from spirit and scope of the present utility model to this utility model.So,
If still these modifications and modification belong to this utility model claim and its equivalent technologies, also in protection domain of the present utility model
Within.
