Description

煞車碟盤brake disc

本創作係有關於一種煞車碟盤，特別是有關於一種用於車輛煞車系統之煞車碟盤技術改良。This creation is related to a brake disc, especially related to a technical improvement of a brake disc used in a vehicle braking system.

按，一般日常生活中常使用車輛代步，而車輛之煞車裝置最常係使用碟煞裝置，碟煞裝置之煞車碟盤固定於車輪上，煞車時係用碟煞裝置之卡鉗挾持住煞車碟盤之二側面以利用磨擦力使煞車碟盤與車輪停止轉動，另外卡鉗與煞車碟盤摩擦時常產生高熱，此現象會使碟煞裝置之煞車效率變低以及使用壽命減短，所以一般會在煞車碟盤上穿設複數散熱孔以增加煞車碟盤之表面積，散熱效果會較良好。TWM382275 、TWM263432等所揭露之煞車碟盤即屬此類。Press, in general, vehicles are often used for transportation in daily life, and the brake device of the vehicle is most often a disc brake device. The brake disc of the disc brake device is fixed on the wheel, and the caliper of the disc brake device is used to hold the brake disc when braking. The two sides use friction to stop the brake disc and the wheel from rotating. In addition, the friction between the caliper and the brake disc often generates high heat. This phenomenon will reduce the braking efficiency of the disc brake device and shorten the service life. A plurality of heat dissipation holes are pierced on the disc to increase the surface area of the brake disc, and the heat dissipation effect will be better. The brake discs disclosed by TWM382275, TWM263432, etc. belong to this category.

然而，在此類習知煞車碟盤皆只設有軸向之散熱孔，煞車碟盤前進之方向與散熱孔之方向垂直，無法利用風向產生與散熱孔之空氣對流，散熱功能較差導致煞車性能降低，存在亟待改善之缺弊。However, such conventional brake discs are only equipped with axial cooling holes, and the forward direction of the brake disc is perpendicular to the direction of the cooling holes, so it is impossible to use the wind direction to generate air convection with the cooling holes, and the poor cooling performance leads to braking performance. Reduced, there are shortcomings that need to be improved urgently.

因此，有必要提供一種新穎且具有進步性之煞車碟盤，以解決上述之問題。Therefore, it is necessary to provide a novel and progressive brake disc to solve the above problems.

本創作之主要目的在於提供一種煞車碟盤，該煞車碟盤之散熱孔的延伸長度斜向於該煞車碟盤之軸向，以增加空氣於該煞車碟盤與空氣接觸之表面積，提高該煞車碟盤之散熱功能。The main purpose of this creation is to provide a brake disc, the extension length of the cooling holes of the brake disc is oblique to the axial direction of the brake disc, so as to increase the surface area of the air in contact with the air on the brake disc, and improve the performance of the brake disc. The heat dissipation function of the disk.

為達成上述目的，本創作提供一種煞車碟盤，包括一環體及至少一散熱孔。該環體定義一軸向，該環體包括位於軸向相對兩側之二側面。各該散熱孔穿設於該二側面之間，各該散熱孔之延伸方向斜向於該軸向。To achieve the above purpose, the invention provides a brake disc, which includes a ring body and at least one cooling hole. The ring body defines an axial direction, and the ring body includes two side surfaces on opposite sides of the axial direction. Each of the heat dissipation holes is disposed between the two side surfaces, and the extending direction of each of the heat dissipation holes is oblique to the axial direction.
