Description
Technical field
The utility model relates to automobile braking device technical field, especially a kind of automobile brake disc.
Background technique
Because the performance of automobile and travelling speed grow with each passing day, be increase the stability that vehicle brakes when running at high speed, disk type brake has become the main flow of current brake system, and brake disc also becomes one of indispensable important accessory of automobile.In braking process, brake disc is because of frictional heat, and temperature raises rapidly, and the friction factor of brake system can be caused to reduce, cause heat fade phenomenon, cause braking distance to increase, therefore the heat radiation of brake disc is the problem being necessary in optimization of vehicle design to consider, and, due to continuous brake in running, make the temperature of brake disc sharply increase and heat dissipation rate is slow, temperature passes to axle head very soon to bearing, brings hidden danger to the driving safety of vehicle.For current brake disc, the design of its main heat sink is dispelled the heat by radiation rib, and radiation rib is generally strip, and the sense of rotation of heat dissipation direction and wheel has certain angle, affects distributing in time of heat.Because brake disc wear-resisting property and heat dispersion directly have influence on working life and the reliability of brake disc, therefore, for these problems, study a kind of good heat dispersion performance, working life is longer, reliability is higher automobile brake drum, have important practical significance.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of perfect heat-dissipating, the automobile brake drum that reliability is higher.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of automobile brake disc, comprise installation disk body, brake disk body and the cylindrical shell being connected described installation disk body and brake disk body, be axis hole in the middle part of described installation disk body, axis hole circumferential distribution has construction bolt hole, described brake disk body comprises front friction disk and back side friction disk, described front friction disk is fixedly connected with some the air draft sheets of back side friction disk by uniform setting radially centered by the disk body center of circle of braking, ventilation channel is formed between adjacent air draft sheet, it is characterized in that: one end of described air draft sheet is fixedly connected with described drum surface, described air draft sheet is provided with at least two through holes, described brake disk body is provided with some thermal vias, described thermal vias and described ventilation channel through, described front friction disk and friction disk surface, the back side are provided with some arc grooves, described drum surface is provided with some vent holes near one end of brake disk body.
Further, described cylindrical shell is round-corner transition with installation disk body, the disk body connection part that brakes.
Further, described air draft plate shape is cuboid shape.
Advantage of the present utility model and good effect are:
A kind of automobile brake disc of the utility model, arc groove establishes brake disc surface heat extraction passage, overcome oil, skidding that water-soaked causes, add brake reliability, thermal vias can make the heat produced during brake be drained by ventilation channel, on radiating fin, the existence of through hole can be able to make heat lost faster with the wind when braking, slow down the warming velocity of brake system during brake, in addition, retarding heat is passed to axle head to bearing by the vent hole of drum surface, more be conducive to brake disc heat radiation, extend its working life.
