Description
Technical field
The invention belongs to brake system of car technical field more particularly to a kind of brake discs.
Background technology
It is well known that brake disc is fixed on the wheel hub of vehicle, it is used cooperatively with brake caliper to realize the system of vehicle
It is dynamic.Fig. 1 shows that a kind of well known brake disc, brake disc ontology 1 include amphidisc, passes through annular array between amphidisc
The radiation tendon 11 of tens of strips links together, and radially, the width ecto-entad of the radiation tendon 11 becomes narrow gradually, adjacent
Gas channel 12 is equipped between two radiation tendons 11, radially, the width ecto-entad of the gas channel 12 also becomes narrow gradually, to
Choke zone 13 is formed at the relatively narrow place of gas channel 12.
When vehicle braking, amphidisc and brake caliper severe friction and generate a large amount of thermal energy, due to the difference of linear velocity,
Along the radial direction of brake disc ontology 1, fever trend gradually increases from inside to outside.When vehicle is advanced, frontal flow of the air-flow from brake disc
Posteriorly, due to the throttling action of choke zone 13, along the radial direction of brake disc ontology 1, heat that air-flow is taken away from inside to outside by
Decrescence small, this runs in the opposite direction with above-mentioned fever trend, thus heat dissipation effect is bad.
Meanwhile gas, when flowing through gas channel 12, the gas contacted with radiation tendon 11 is the main body for taking away heat, and air-flow is logical
Any location contacts in air flow stream and brake disc among road 12, thus its heat dissipation effect is limited, this is also to influence heat dissipation effect
One of the reason of fruit.
In order to improve thermal diffusivity, by the thickness of inside brake disk body (disk body for being equipped with ring flange), radially ecto-entad is gradual
Thinning, positioned at axis hole vicinity, radially ecto-entad gradually thickens.Using the above structure, it is carried out by way of wall thickness reduction
Heat dissipation, although the effect for improving heat-sinking capability can be played, thermal diffusivity still cannot reach demand in actual work.
Moreover, brake caliper will clamp the peripheral part of brake disc ontology 1 when braking, this part needs to undertake very strong system
Kinetic moment, still, on the peripheral part of brake disc ontology 1, adjacent two radiation tendon 11 but from relatively far away from, therefore brake disc ontology
1 peripheral part intensity is low, this will directly affect the service life of brake disc.It is learnt through practice, as long as cracked on disk body,
It mostly radially extends and is grown, and the structure that radiation tendon 11 radially extends, it can not stop that the radial direction of crackle is raw
Long, this can also influence the service life of brake disc.
