Abstract
The utility model relates to the technical field of brake discs, in particular to a carbon ceramic brake disc with 24 ventilation ducts. Including the brake disc body, a plurality of ventilation holes have been seted up on the brake disc body, the middle part of brake disc body inwards extends and forms the air reinforcement to seted up the bolt mounting hole, 24 ventilation grooves have been seted up to the lateral wall of brake disc body, the ventilation hole is all arranged in ventilation groove upper end, and with ventilation groove intercommunication. According to the utility model, the vent holes are formed in the brake disc body, are arranged at the upper ends of the vent grooves and are communicated with the vent grooves, and are arranged along the spiral line from the structural aspect, so that the attractive effect is achieved besides the effects of heat dissipation, water drainage and dust exhaust; the ventilation grooves are designed to be changed from small to large along the radial direction, so that the air inflow of the ventilation grooves on the outer edge of the brake disc is increased, and the heat dissipation of the brake disc is facilitated.
Description
Technical Field
The utility model relates to the technical field of brake discs, in particular to a carbon ceramic brake disc with 24 ventilation ducts.
Background
After the automobile is continuously braked, the temperature of a brake disc is rapidly increased, the friction coefficient of the brake disc is reduced due to high temperature, the braking effect is influenced, and heat fading is generated. The brake disc material that is most commonly used on the market at present is grey cast iron, and the advantage is that it is easy to make, and the cost is lower, and the shortcoming is heavy, and wearability is poor, and life is low, and high temperature heat fading is obvious, and coefficient of friction is not high etc..
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a carbon ceramic brake disc with 24 ventilation ducts, and aims to solve the problems in the background art.
In order to solve the technical problem, the scheme of the utility model is as follows: the utility model provides a 24 ventiduct's carbon pottery brake disc, includes the brake disc body, a plurality of ventilation holes have been seted up on the brake disc body, the middle part of brake disc body inwards extends and forms the air channel to seted up the bolt mounting hole, 24 ventilation grooves have been seted up to the lateral wall of brake disc body, the ventilation hole is all arranged in ventilation groove upper end, and with ventilation groove intercommunication.
The bolt mounting hole is arranged in the radial direction of the ventilating rib.
The diameters of the vent holes are all 5 mm.
The width dimension of the ventilation groove becomes gradually larger along the radial direction.
Compared with the prior art, the utility model has the beneficial effects that:
according to the utility model, the vent holes are formed in the brake disc body, are arranged at the upper ends of the vent grooves and are communicated with the vent grooves, and are arranged along the spiral line from the structural aspect, so that the attractive effect is achieved besides the effects of heat dissipation, water drainage and dust exhaust; the ventilation grooves are designed to be changed from small to large along the radial direction, so that the air inflow of the ventilation grooves on the outer edge of the brake disc is increased, and the heat dissipation of the brake disc is facilitated.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a cross-sectional view of the present invention.
Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1-2, the carbon ceramic brake disc with 24 ventilation ducts comprises a brake disc body 1, wherein a plurality of ventilation holes 2 are formed in the brake disc body 1, the middle of the brake disc body 1 extends inwards to form ventilation ribs 5 and is provided with bolt mounting holes 3, 24 ventilation grooves 4 are formed in the side wall of the brake disc body 1, and the ventilation holes 2 are all arranged at the upper ends of the ventilation grooves 4 and are communicated with the ventilation grooves 4. In the utility model, the brake disc body 1 is made of carbon ceramic material, and the brake disc body 1 made of carbon ceramic material has the advantages that: the density of the carbon ceramic material is 2g/cm3The weight of the whole vehicle is light, and lighter unsprung mass can be brought to the whole vehicle; can bear the high temperature of 1000 ℃; the wear rate is low, and the average service life can reach 8-12 km; the safety of braking can be greatly improved no matter the friction coefficient is stable in a dry state or a wet state.
The bolt mounting holes 3 are provided in the radial direction of the air-channeled bar 5. The quantity of bolt mounting hole 3 sets up to 12, arranges the radial direction at air reinforcement 5, guarantees the stress strength of brake disc. The diameters of the vent holes 2 are all 5 mm.
The width dimension of the ventilation slot 4 becomes gradually larger in the radial direction. Specifically, the width of the ventilation groove 4 is gradually increased from 19mm to 38mm along the radial direction, and the ventilation groove 4 is designed to be gradually increased along the radial direction, so that the air inflow of the ventilation groove 4 on the outer edge of the brake disc body 1 is increased, and the heat dissipation of the brake disc is facilitated.
Specifically, the vent holes are formed in the brake disc body, are arranged at the upper ends of the vent grooves and are communicated with the vent grooves, and are arranged along the spiral line in the structural aspect, so that the attractive effect is achieved besides the effects of heat dissipation, water drainage and dust exhaust; the ventilation grooves are designed to be changed from small to large along the radial direction, so that the air inflow of the ventilation grooves on the outer edge of the brake disc is increased, and the heat dissipation of the brake disc is facilitated.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
