Description

A kind of automobile brake disc

Technical field

This utility model relates to technical field of automobile, more particularly, it relates to a kind of automobile brake disc.

Background technology

Along with the continuous progress of society, automobile has become as the requisite vehicles of people's daily life.With People and quality of the life is pursued more and more higher, and the frequent generation of vehicle accident so that people are to automobile Safety is paid attention to all the more.Wherein the brake disc of automobile is to affect the link that automotive safety is the most crucial.

Brake disc essence be profile be circular dish dress object, make brake disc with the biography of automobile during running car Moving axis rotates together, and during braking automobile, brake caliper is clamped brake disc two sides by brake block and produced brake force, Thus car deceleration or parking.Vehicle accident incessantly will be measured into, the person to car owner if stopped during braking automobile Safety and property cause irremediable loss, it can be seen that the importance of brake disc.

Brake block and brake disc can grind powder under high-speed friction, but the disk biside of existing brake disc is equal Being shiny surface, powder is attached in disk both side surface make braking time increase, and powder is attached to brake disc simultaneously The heat that surface makes brake disc produce in brake process can not the most outwards transmit, due to brake disc expanded by heating Reason, make brake disc shape generation micro-variations.

And automobile is after the rainy day is run or paddles, and owing to brake disc does not has discharge structure, has hydrops and accumulates in Brake disc intracavity, it is impossible to discharging hydrops and the dirt of residual in time, extended stationary periods, at brake disc intracavity, has long-pending The hydraulic performance declines such as water and dirt are attached on brake block, make brake disc corrosion, heat radiation, if things go on like this also result in Poor stop or brake fade, make safety, reliability and degradation in service life.

Accordingly, because prior art exists above-mentioned technological deficiency, it is that those skilled in that art are urgently to be resolved hurrily Technical problem.

Preferably, also include that rhone, described outer disc edge are provided with the rhone of annular.

Preferably, also including that reinforcement, described reinforcement are that annular is arranged, described reinforcement is located at described annular Inside groove.

Preferably, described groove medial extremity width is less than outboard end width.

Of the present utility model have the beneficial effect that by the improvement to existing brake disc so that it is heat radiation, draining and Dust removal performance is higher, improves the application effect of its entirety.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to reality Execute the required accompanying drawing used in example or description of the prior art to be briefly described, it should be apparent that, describe below In accompanying drawing be only embodiments more of the present utility model, for those of ordinary skill in the art, not On the premise of paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is structural representation of the present utility model；

Fig. 2 is sectional view of the present utility model；

In figure: 1 outer disk；2 inner discs；3 installing holes；4 dead eyes；5 grooves；6 air vents；7 wearing layers； 8 cannelures；9 external through holes；10 rhones；11 reinforcements.

Detailed description of the invention

This utility model provides a kind of automobile brake disc, enhances heat-sinking capability, improves drainage performance, from Dust removing effects is more preferable, extends the service life of brake disc.

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is entered The description that row is clear and detailed, it is clear that described embodiment is only a part of embodiment of the present utility model, Rather than whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not doing Go out all other embodiments obtained under creative work premise, broadly fall into the scope of this utility model protection.

A kind of automobile brake disc as illustrated in fig. 1 and 2, including outer disk 1, inner disc 2, installing hole 3, bearing Hole 4, groove 5, air vent 6, wearing layer 7, cannelure 8 and external through hole 9, solid in the middle part of described outer disk 1 Surely having inner disc 2, described inner disc 2 center to be provided with dead eye 4, the described outer uniform ring of dead eye 4 is wound with multiple peace Dress hole 3, described outer disk 1 is provided with multiple air vent 6 around described inner disc 2, and described air vent 6 is applied in In described outer disk 1, described outer disk 1 edge ring is wound with wearing layer 7, passes through cannelure in the middle part of described air vent 6 8 are connected, and described cannelure 8 connects described outer disk 1 edge by the external through hole 9 being radially arranged, described Outer disk 1 surface is provided with a plurality of groove 5, and described groove 5 one end is tangent with described inner disc 2 edge, described recessed Groove 5 other end connects with described outer disk 1 edge.Air vent 6 can be connected by cannelure 8, convenient by The wind that air vent 6 enters flows in cannelure 8, it is achieved the cooling effect to outer disk 1, and when cannelure 8 After water inlet, outer row can be realized by external through hole 9.
