Description
本發明係關於一種碳陶瓷煞車碟盤，特別是關於一種具提升煞車性能之結構之碳陶瓷煞車碟盤。 The present invention relates to a carbon-ceramic brake disc, in particular to a carbon-ceramic brake disc with a structure for improving braking performance.
習知常見的煞車裝置為鼓式煞車與碟式煞車兩種，而這兩種煞車裝置都是利用來令片去磨擦煞車鼓或是煞車碟盤，透過摩擦力來達到減速的功效，同時煞車碟盤與輪圈連接，達到使車輛減速或停止的目的。 Commonly known brake devices are drum brakes and disc brakes. Both of these brake devices use pads to rub the brake drum or the brake disc. The friction is used to achieve the effect of deceleration, while braking The disc is connected with the rim to achieve the purpose of decelerating or stopping the vehicle.
一般市面上常見到的煞車碟盤，係以不鏽鋼或鋁合金等金屬材質作為主要構成物，但是金屬煞車碟盤的重量較重，其耐熱度與抗變形等性能也比較差，且其摩擦係數隨溫度升高而降低，因此於高速競賽時，加裝金屬煞車碟盤不僅會增加該車輛整體重量，且於長時間致動時生熱時，易發生制動力下滑與煞車碟盤變形的情況。 Generally common brake discs on the market are made of metal materials such as stainless steel or aluminum alloy as the main components. However, the weight of metal brake discs is heavier, its heat resistance and deformation resistance are relatively poor, and its friction coefficient It decreases with the increase of temperature. Therefore, in high-speed racing, the installation of metal brake discs will not only increase the overall weight of the vehicle, but also cause the braking force to drop and the brake discs to deform when heat is generated during prolonged actuation. .
陶瓷具備硬度、耐磨、耐高溫等特性，因此常被運用於光電、半導體、與電器設備上，純陶瓷材料不具備延展性，使其應用範圍受到限制，利用碳纖維布韌化之碳陶瓷複合材料，可彌補上述的缺點，並保持陶瓷的優點，可 以應用在更廣泛的領域，例如：以碳纖維/碳陶瓷複合材料所製成的陶瓷煞車碟盤，具備導熱性良好，且熱輻射係數高而散熱性優異，摩擦係數不會因為溫度上升而下降等優點，因此在劇烈煞車產生高溫的情形下，比金屬煞車碟盤更安全，碳/陶瓷煞車碟盤已普遍應用於比賽型的重機與賽車，甚至用在一般高級房車。 Ceramics have the characteristics of hardness, wear resistance, and high temperature resistance, so they are often used in optoelectronics, semiconductors, and electrical equipment. Pure ceramic materials do not have ductility, which limits their application range. Carbon-ceramic composites toughened by carbon fiber cloth Material, can make up for the above shortcomings, and maintain the advantages of ceramics, can It can be used in a wider range of fields. For example, ceramic brake discs made of carbon fiber/carbon ceramic composite materials have good thermal conductivity, high thermal radiation coefficient and excellent heat dissipation, and the friction coefficient will not decrease due to temperature rise Therefore, it is safer than metal brake discs when severe braking generates high temperature. Carbon/ceramic brake discs have been widely used in racing heavy machines and racing cars, and even in general high-end touring cars.
雖然碳陶瓷複合材料具由上述優點，但習知使用碳陶瓷複合材料製作煞車碟盤，會面臨陶瓷不具備延展性而易脆或易裂的缺點，尤其是在煞車碟盤與輪圈的固定處，不論是鎖螺絲固定或煞車時，皆會對該部位造成較大的應力，容易損壞陶瓷煞車碟盤。 Although carbon-ceramic composites have the above-mentioned advantages, the conventional use of carbon-ceramic composites to make brake discs has the disadvantages that ceramics are not ductile and are brittle or cracked, especially when fixing the brake discs and rims. No matter it is fixed with a lock screw or when braking, it will cause greater stress on the part and easily damage the ceramic brake disc.
