Abstract
Disclosed by the utility model is a kind of ventilated brake disc, including the interior disk, outer disk and disk cap set gradually, it is connected by dowel between the interior disk and outer disk, it is characterized in that, it connects to form reversing airway structure by connection wall area between the interior disk inner ring and disk cap outer ring, connection wall area interior thickness is more than both sides, and the connection wall area is equipped with boss with disk cap angle, to mitigate the warpage of brake disc, while reinforcing the intensity of brake disc.The air outlet of brake disc is arranged on the outside of disk cap, avoids being hindered by mud guard by the air between outer disk and interior disk by the design of reversing airway structure, can accelerate brake disc inner air convection and improve the cooling effect of brake disc.
Description
Technical field
The utility model is related to automotive disc brakes, more particularly to a kind of ventilated brake disc.
Background technology
As automobile is more and more universal, people are also higher and higher to automobile brake perfrmance requirement, and disk brake is in car
On application it is also all the more universal.It in the more area in slope road, frequently brakes, the constant temperature of brake disc is easily caused to increase.Brake disc
The raising of temperature will cause brake block friction coefficient to fail, aggravate the abrasion of brake block, the decline of brake efficiency and brake block longevity
The reduction of life, and lead to brake disc warpage, braking shake when high speed.On the market, the dowel of ventilated brake disc has
The problem of leaf structure and column structure, the structural improvement solid brake disc poor heat radiation, reduce brake temperature.But
It is that its structure is easy, into particle, to cause brake disc ventilation slot to be blocked, be unfavorable for radiating.To prevent dust from corroding brake, need
It is equipped with mud guard, but mud guard affects the air flow direction of brake, reduces the heat dissipation performance of brake disc.Brake disc exists simultaneously
Situation of being heated when braking is uneven, and it is excessively high to easily cause local temperature, brings warpage, causes heat shake.
Utility model content
In view of background technology, the technical problem to be solved by the present invention is to provide a kind of ventilation systems
Moving plate, substantially improve because brake disc brake when heat dissipation performance effect it is not ideal enough due to cause warpage, heat shake the problem of.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that realize：A kind of ventilation system
Moving plate, including the interior disk, outer disk and the disk cap that set gradually, are connected between the interior disk and outer disk by dowel,
It is characterized in that, connecting to form reversing airway structure by connection wall area between the interior disk inner ring and disk cap outer ring.
Connection wall area interior thickness is more than both sides.
The connection wall area is equipped with boss with disk cap angle.
The utility model has the beneficial effects that：The air outlet of brake disc is arranged outside disk cap for the design of reversing airway structure
Side avoids being hindered by mud guard by the air between outer disk and interior disk, can accelerate brake disc inner air convection and carry
The cooling effect of high brake disc.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is brake disc deformation schematic diagram.
Specific implementation mode
As shown in Figure 1, a kind of ventilated brake disc, including the interior disk 2, outer disk 3 and the disk cap 1 that set gradually, it is described in
It is connected by dowel 5 between disk 2 and outer disk 3, passes through connection wall area 4 between 2 inner ring of interior disk and 1 outer ring of disk cap
Connection forms reversing airway structure, and the section in the connection wall area 4 is arc-shaped, it is assumed that the interior disk 2 is located in outer disk 3
Side, mud guard 6 are located at the top of interior disk 2, and disk cap 1 is located at below outer disk 3, the connection wall area 4 start from 2 inner ring of interior disk to
Lower extension is connect with 1 outer ring of disk cap, will downwards be drawn by the air between interior disk 2 and outer disk 3.Since mud guard 6 is set
It sets above interior disk 2, flows to mud guard 6 by the air between interior disk 2 and outer disk 3 in order to prevent, hindered by mud guard 6
It blocks, influences heat dissipation effect, therefore, reversing airway structure is set.Reversing airway structure, that is, connection wall area 4 connects interior disk 2 and disk cap
1, make, by that side of air flow direction far from mud guard between interior disk 2 and outer disk 3, air outlet to be arranged outside disk cap
Side can accelerate brake disc inner air convection in this way, improve the heat dissipation of brake disc.
As shown in Fig. 2, brake disc is in braking, heating surface concentrates on the contact surface of brake disc and brake bush, system
Moving plate is because of uneven heating, and the temperature of disk and Pan Maochu differ, and corresponding swell increment also differs, brake disc drawing godet cap,
Disk cap is set to increase close to the radius of brake disc side, to form the warpage of brake disc inwardly.The result of warpage deformation
It will lead to brake block eccentric wear, brake disc eccentric wear, brake disc working surface becomes uneven with brake block contact after deformation, into
And cause the local heating more concentrated, excessive wear.
That is, constantly being hit by the high temperature air between interior disk and outer disk in the middle part of connection wall area, connection wall
It is therefore easy to generate deformation in the middle part of area, meanwhile, the deformation in connection wall area can cause the expansion of the angle between connection wall area and disk cap
Greatly.
As shown in Figure 1, this deformation in order to prevent, 4 interior thickness of connection wall area is more than both sides, that is, thickeies connection wall
The middle part of area 4, the connection wall area 4 and the angle of disk cap 1 are equipped with boss 7, and connection wall area is made to be thickeied with disk cap junction, i.e., into
The connection that one step is reinforced between connection wall area and disk cap reinforces the intensity of brake disc to mitigate the warpage of brake disc.
