Description
Technical field
The utility model is related to a kind of commercial vehicle brake disc.
Background technology
Brake has disc brake and drum brake to also have pneumatic brake at present, and more cooked car is all much drum after shroud.Present car
All it is disc brake before and after a lot.Because disc brake is compared with the good heat dissipation of drum brake, under high speed on-position, it is not easy to produce heat fading,
So its high speed good braking effect.But in low-speed cold brake, braking effect is not so good as drum brake.Price is more expensive than drum brake.So now very
Many intermediate cars use full brake, and general car using drum after shroud, and relative low speeds, and need the big card of brake force
Car, bus, still using drum brake.
The brake disc of disc brake is exactly a round plate, and it is also what is rotated when car is advanced.Brake caliper be exactly for
Two panels is clamped brake disc and produces brake force.The brake disc that it is rotated against is fixed.It is exactly that it clamps and stops when touching on the brake
Hull plays a part of to slow down or stops.Drum brake is sealing, and shape also has much be brake disc at home as drum type.OK
It is to rotate during car.Drum brake the inside is fixed with the brake shoe of two arcs or semicircle.Two brake shoes are just when touching on the brake
Outer in the presence of wheel cylinder, prop up the rub inwall of brake rim of brake shoe and play a part of to slow down or stop.
Disc type brake disc (dish) is divided into solid disc (monolithic disk) and air channel disk (biplate disk).We are easier understanding to solid disc type, say
Bai Liao, is exactly solid.Air channel disk (Vented Disc), as the term suggests there is ventilative effect.From in terms of appearance, it is circumferentially
There are many holes for leading to the center of circle empty, referred to as air channel.Automobile, by cross-ventilation at air channel, reaches the purpose of radiating in enforcement
, it is more better than solid formula radiating effect.Most of car is all forerunner, and the abrasion of shroud frequency of use meter is larger, therefore uses
Primary air separating duct disk, rear solid disc (monolithic disk).Certainly all it is air channel disk before and after also having, but going against accepted conventions of can't differing from of manufacturing cost.
Current existing brake disc radiating effect is bad, and structural stability is not high, it is impossible to which enough holding disk body outers will not glue
Attached debris.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of good heat dissipation effect, and structural stability is high, can keep
Disk body outer will not adhere to the commercial vehicle brake disc of debris.
To solve the above problems, the utility model is adopted the following technical scheme that：
A kind of commercial vehicle brake disc, including disk body and lid, the disk body middle part are provided with through hole, between the lid is in
Every being located on disk body, dowel, the dowel circular array distribution, the disk body are provided between the disk body and lid
Surface is provided with arc groove and circular port, and the lid middle part is provided with axis hole, is evenly equipped with the lid on the outside of the axis hole
Screwed hole, is provided with cavity in the disk body, support bar is provided with the cavity, and the support bar is described in being equally spaced
Support bar is integrally formed with disk body, and the disk body outer is provided with polytetrafluoroethylene floor.
Preferably, the arc groove is provided with six, arc groove can increase the area of dissipation of disk body.
Preferably, the circular port is distributed in the shape of a spiral, circular port can be connected with the cavity in disk body, keep air
Circulation.
Preferably, the height of the support bar is 1cm, although support bar keeps disk body, there is cavity inside, can still protect
Hold sound construction.
Preferably, the polytetrafluoroethylene floor thickness is more than 4mm, the surface tension of polytetrafluoroethylene (PTFE) is small, does not adhere to miscellaneous
Matter.
Preferably, the polytetrafluoroethylene floor is fixedly connected with disk body, epoxy resin is smeared in polytetrafluoroethylene floor inner side
Glue is pasted in disk body outer.
The beneficial effects of the utility model are：Cavity is provided with the disk body of setting, disc surfaces are provided with arc groove
And circular port, circular port can connect with the cavity in disk body, maintain the circulation of air, and keep good heat dissipation effect；The disk body of setting
Dowel is provided between lid so that have interval between disk body and lid, good heat dissipation is kept, while holding structure stability
It is high；The disk body outer of setting is provided with polytetrafluoroethylene floor, and surface tension is small, not stuck foreign matter.
Brief description of the drawings
Fig. 1 is a kind of top view of commercial vehicle brake disc of the utility model.
Fig. 2 is a kind of profile of commercial vehicle brake disc of the utility model.
Specific embodiment
As depicted in figs. 1 and 2, a kind of commercial vehicle brake disc, including disk body 1 and lid 2, the middle part of the disk body 1 are set
There is through hole 3, disk body 1 uses gray cast iron HT250, and the lid 2 is located on disk body 1 in interval, between the disk body 1 and lid 2
Dowel 4 is provided with, disk body 1, lid 2 and dowel use gray cast iron HT250 moulding by casting, and disk body 1 to be adopted in shaping
With mould cavity 9 and support bar 10, the distribution of the circular array of the dowel 4, the setting of the surface of the disk body 1 are internally formed at it
There are arc groove 5 and circular port 6, the arc groove 4 is provided with six, and the circular port 6 is distributed in the shape of a spiral, the lid 2
