Abstract
A kind of electric vehicle brake hub, belongs to electric vehicle engineering field.It provides a kind of intensity height, the electric vehicle brake hub of good heat dissipation effect.The clutch disk and hub body one end integrally connected, clutch disk offers center screw and multiple bolts hole, it is recessed inwardly in the middle part of the external periphery of hub and forms annular protrusion on periphery in hub body, the enhanced composite ceramic layer spraying is covered on the lateral surface of annular protrusion, the multiple ring stiffener one is secure around the recess of the external periphery of hub, and multiple ring stiffeners one are successively setting up and down.The annular protrusion of the utility model plays the role of reinforcement to hub body, enhanced composite ceramic layer can effectively mitigate brake-shoe and wear to annular protrusion, reduce the loss of material, reduce production cost, the utility model inner space is big, good heat dissipation effect, multi-layer annular reinforcing rib one improve the intensity and heat dissipation effect of hub body.
Description
Technical field
The utility model belongs to electric vehicle engineering field, more particularly to a kind of electric vehicle brake hub.
Background technique
Brake hub is also known as brake hubs, is safety component crucial on automobile.Brake hub passes through the friction between brake block
Power checks wheel of the bus, is both needed to be equipped with brake hub on medium-sized and heavy vehicle.When driving, can brake hub pacify
Entirely reliably brake it is extremely important, if brake failure in emergency circumstances occurs, it will cause safety accident, or even vehicle is caused to ruin people
Die major break down.Therefore, very strict to brake hub requirements.
Brake hub on automobile, that there are intensity is inadequate, heat dissipation effect is bad, stress position easy fracture, service life
Low disadvantage.
Summary of the invention
In view of the deficiency of the prior art, the utility model provides that a kind of intensity is high, good heat dissipation effect it is electronic
Automotive brake hub.
Technical solution adopted in the utility model is：A kind of electric vehicle brake hub, including hub body and clutch disk；Institute
Clutch disk and hub body one end integrally connected are stated, clutch disk offers center screw and multiple bolts hole, the electric car
Brake hub further includes enhanced composite ceramic layer and multiple ring stiffeners one, is recessed inwardly simultaneously in the middle part of the external periphery of hub
Annular protrusion is formed on periphery in hub body, the enhanced composite ceramic layer spraying is covered on the lateral surface of annular protrusion
On, the multiple ring stiffener one is secure around the recess of the external periphery of hub, and multiple ring stiffeners one are successively
It is setting up and down.
The beneficial effects of the utility model are：
The annular protrusion of the utility model plays the role of reinforcement to hub body, and brake-shoe is furthermore mounted on annular protrusion
Place, when in use, enhanced composite ceramic layer can effectively mitigate brake-shoe and wear to annular protrusion, enhanced composite ceramics
Layer reduces the loss of material, reduces production cost, the utility model inner space is big, dissipates without filling side in hub body
Thermal effect is good, and multi-layer annular reinforcing rib one improves the intensity and heat dissipation effect of hub body, improves service life.
Detailed description of the invention
Fig. 1：The utility model main sectional view；
Fig. 2：The utility model structure diagram；
Wherein：1- hub body；1-1 annular protrusion；2- clutch disk；2-1- center screw；2-2- bolt hole；3- is enhanced
Composite ceramic layer；4- ring stiffener one；5- ring stiffener two.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of electric vehicle brake hub, including hub body 1 and clutch disk 2；The clutch disk 2 with
1 one end integrally connected of hub body, clutch disk 2 offer center screw 2-1 and multiple bolt hole 2-2, the electric vehicle brake
Hub further includes enhanced composite ceramic layer 3 and multiple ring stiffeners 1, is recessed inwardly simultaneously in the middle part of 1 outer circumference surface of hub body
Annular protrusion 1-1 is formed on 1 inner peripheral surface of hub body, intensity is high at annular protrusion 1-1, and the enhanced composite ceramic layer 3 sprays
Painting is covered on the lateral surface of annular protrusion 1-1, and annular protrusion 1-1 and enhanced composite ceramic layer 3 have vertical mounting plane,
And the brake-shoe of brake is mounted on enhanced composite ceramic layer 3, the multiple ring stiffener 1 is secure around
The recess of 1 outer circumference surface of hub body, multiple ring stiffeners 1 are successively setting up and down.
The material of enhanced composite ceramic layer 3 carbon fiber and SiC synthesis under 1700 degree of high temperature has light-weight, strong
The advantage that degree is high, wearability is good and heat-resist.
The height of the multiple ring stiffener 1 is no more than 5mm.Make it have good heat dissipation effect.
The outer circumference surface of the multiple ring stiffener 1 is concordant with 1 outer circumference surface of hub body to be arranged.Its effect is：Just
In the installation of hub body 1.
The electric vehicle brake hub further includes ring stiffener 25, and the 1 lateral surface other end of hub body and annular are reinforced
25 integrally connected of muscle.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
