The wheel hub that a kind of drum brake and disc brake can be reequiped mutually
Technical field
The utility model belongs to locomotive wheel hub technical field, is related to the wheel hub that a kind of drum brake and disc brake can be reequiped mutually.
Background technology
Drum brake is made up of the relevant connecting rod such as shoe sole, wheel cylinder, brake shoes, spring, tip nail, brake rim.Mesh
Before be generally mounted to trailing wheel.The cost of drum brake is relatively low, absolute brake Li Genggao, and the brake rim inner face of drum brakes is exactly brake dress
Put the position for producing brake torque.In the case where identical brake torque is obtained, the diameter of the brake rim of drum type braking device can
With the also small upper many of the brake disc than disk type brake, the device drum brakes among the confined space of wheel rim is merely able to.
It is high when disc brake constitutes brakes by the braking clamp of a brake disk being connected with wheel and disk border
Pressure brake fluid promotes brake block to be allowed to clamp brake disc so as to produce braking effect.Disk type brake is also in disc brake sometimes, it
It is divided to ordinary disc-type to brake and two kinds of ventilated disc brake.Ventilated disc brake is that many circular vents are got out in card, or
It is the air vent that ventilation slot is cut out on the end face of disk or rectangle is precast.Ventilated disc brake utilizes distinguished and admirable effect, and its is cold and hot
Effect is more preferable than ordinary disc-type brake.The major advantage of disc brake can be braked rapidly when high speed is braked, radiating effect
Better than drum brakes, the constancy of brake efficiency is good.A kind of disc brake of electric motor car as disclosed in patent CN201520270660.1
Wheel hub, including wheel rim, spoke, bearing and brake disc, wheel rim are fixed on spoke outside, and the disc brake hub of electric motor car also includes being used for
The plate-like connection sheet of connection spoke and bearing, bearing one end is through spoke centre and is welded on spoke, and the bearing other end is passed through
Plate-like connection sheet centre is simultaneously welded in plate-like connection sheet, and the outward flange of plate-like connection sheet is welded on spoke, the bearing other end
End be additionally provided with mounting disc for fixing brake disc.
Some wheels need to install drum brake, and some wheels need to install disc brake, but the wheel hub of above-mentioned patent is all disc brake
Or the individually designed manufacture of drum brake, make a clear distinction between good and evil between the two, it is impossible to mutually repacking, lack any of which, it is required for
Remanufacture, bother very much.
The content of the invention
The above mentioned problem that the utility model exists for existing technology, there is provided what a kind of drum brake and disc brake can be reequiped mutually
Wheel hub, technical problem to be solved in the utility model is:How disc brake hub and drum brake wheel hub changing between the two is improved
Dress property.
The purpose of this utility model can be realized by following technical proposal:
The wheel hub that a kind of drum brake and disc brake can be reequiped mutually, including for installing the mounting flange of disk brake, spoke, in cylinder
The brake rim and wheel rim of shape, the brake rim are fixedly connected with by spoke and the wheel rim, and the two ends of the brake rim are respectively spacious
Mouth end and blind end, it is characterised in that the wheel hub also includes one piece of cover plate relative to brake rim independence, the cover plate passes through
It is welded and fixed or is detachably fixed or be fixed at the opening end of the brake rim by rivet interlacement, in the cover plate
Portion is plugged with the bushing two through the cover plate, and the inner of the bushing two is fixedly connected with the cover plate, outside the bushing two
End is mutually fixed with the mounting flange, and the bushing one, bushing two and brake rim are coaxially disposed.
Its principle is as follows:Used when as disc brake hub under normality, the general rounded or triangle of mounting flange is installed
Some connecting holes are offered on flange, when disc brake hub is arranged on locomotive, the disk brake on locomotive is bolted
On connecting hole, so as to realize being fixedly connected for mounting flange and disk brake.In general, the wheel shaft of the wheel of locomotive passes through lining
Set two, wheel shaft is general to have bearing part and bushing two between, reduces the friction for rotating.Cover plate and brake rim are welded and fixed to be easy to add
Work, needs violence damage when unloading, but damages also not too large, and the effect that bushing two and brake rim are coaxially disposed is to ensure wheel shaft
It is coaxial with brake rim, so ensure that brake rim can be reactivated the part for drum brake.When needing to be adapted as drum brake wheel hub,
Only need to unload cover plate from the opening end of brake rim, it is this unload can be lossless dismounting, or violence broken ring,
So that cover plate and bushing thereon two and mounting flange are separated from brake rim, so, the opening end of brake rim is enabled from newly, can
It is arranged in the inner chamber of brake rim from open-mouth with by the miscellaneous part of drum brakes, so as to the wheel hub is adapted as into drum brake wheel
Hub;Similarly, when drum brake wheel hub is too many and disc brake hub very little when, cover plate is fixed on the open-mouth of brake rim, then will lining
Set two and mounting flange are fixed and just drum brake wheel hub can be adapted as into disc brake hub on the cover board.Rivet interlacement needs to a certain degree
Violence damage, comparatively damage little, dismantle more convenient.This wheel hub is fixed using an independent cover plate and brake rim
Connection so that both can be separated so that the wheel hub of disc brake type and the wheel hub of drum brake formula can be reequiped mutually, improves general
