?剎車片“神秘”的摩擦材料涂層
有愛車的動手達人在買到某些品牌的剎車片后,發(fā)現(xiàn)摩擦材料表面有一層涂層,涂層寬度或?qū)捇蛘?,方向或橫或縱或斜,顏色更是五花八門。這是什么東東?沒見過啊。
人類本能對未知的東西保持敬畏,于是此物在心中的地位自然升高幾分。然而,達人顯然不會滿足于未知。今天,就由小布帶大家來認識一下神秘的摩擦材料涂層。
想知道涂層是做什么用的,問誰?當(dāng)然是發(fā)明者。打開美國zhuanli商標(biāo)局網(wǎng)站(www.uspto.gov),搜索coating & brake,一篇名為“一種應(yīng)用于剎車系統(tǒng)摩擦材料上的摩擦表面涂層”的zhuanli浮出水面。這就是今天我們要學(xué)習(xí)的zhuanli了。

BACKGROUNDOF THE INVENTION
For the tribological system disk brake, a desired coefficient of friction arisesbetween a disk brake a brake lining only after a certain number of brakingactions. These braking actions, in which a new friction pairing which is notyet run-in possesses a coefficient of friction which greatly depends on therunning-in state, are also designated as running-in braking actions.
對于摩擦系統(tǒng)盤式制動器,制動片和制動襯片之間的摩擦系數(shù)只有經(jīng)過一定數(shù)量的制動后,才會產(chǎn)生達到理想值。這種制動稱作磨合制動,期間,新的摩擦對偶還未摩擦好,其摩擦系統(tǒng)主要取決于磨合狀態(tài)。
For the coefficient of friction, geometrical adaptations between the brake liningand the brake disk a tribological boundary layer constitution, generallydesignated as friction coal, are essential influence parameters. Only when theboundary layer the geometry are sufficiently constituted by the running-inbraking actions, we come with the coefficient of friction of the system to theso-called steady condition. Thus, the friction pairing reaches a run-in stateand thus the desired coefficient of friction level only after a relatively highnumber of running-in braking actions.
制動襯片和制動盤之間的幾何結(jié)構(gòu)和摩擦邊界層通常被稱為摩擦碳,其是摩擦系數(shù)必不可少的影響參數(shù)。只有當(dāng)邊界層和幾何結(jié)構(gòu)被充分磨合,我們才得到所謂的穩(wěn)定條件摩擦系數(shù),摩擦對偶達到磨合好的狀態(tài)。因此,期望的的摩擦系數(shù)只有經(jīng)過一個相對多次的磨合才能達到。
Under certain automotive engineering operating conditions, there comes however toproblems due to the difference between the run-in system the run-insystem. For example truck trailers are brake tested after manufacturing.Referred to nine tons axle load extrapolated to 6,5 bar, the vehicle must reachat least 45% (50%) deceleration. The decelerations must also be dynamicallyreached when testing the brake system of the double train on the road by higherspeeds. Here it has been found as a problem that a new disk brake system in notrun-in state most of the time does comply with the above mentionedrequirements.
在一定的汽車工程運行條件下,由于系統(tǒng)的磨合和未磨合的差異,產(chǎn)生了一些問題。例如卡車拖車是在制造后進行的制動試驗。方法為使用九噸的軸載外推到6.5桿,車輛必須達到至少45%(50%)的減速。在路面使用更高速度測試雙層列車的制動系統(tǒng)時,也必須達到減速要求。在這里發(fā)現(xiàn)了一個問題,一個新的盤式制動系統(tǒng)在未磨合的狀態(tài)時,大部分的時候都不符合上述要求。
The aim of this invention is to make available an improvement of the tribologicalsystem brake, especially of a disk brake, which eliminates the above mentioneddisadvantages also reaches sufficient coefficients of friction in notrun-in state.
本發(fā)明的目的是改善摩擦系統(tǒng)的制動,特別是盤式制動器,從而消除上述缺點,并在未磨合的狀態(tài)下,達到足夠的摩擦系數(shù)。
This aim is achieved by a friction surface coating of the above mentioned type andby a brake lining of the above mentioned type, wherein the friction surfacecoating contains 0 to 30% in weight phenolic resin, 5 to 95% in weight aluminumoxide, 0 to 20% in weight silicium oxide, 5 to 75% bonding agent, 0 to 10% in weightinterlacing agent, 0 to 50% in weight elastomer 0 to 50% in weight filler.
這個目標(biāo)是通過摩擦表面涂層和襯片來實現(xiàn)的,其中的摩擦表面涂層含有0至30%重量的酚醛樹脂,5~95%重量的鋁氧化物,0至20%重量的硅氧化物,5至75%的粘接劑,0到10%重量的交錯劑,0 50%重量的彈性體和0~50%重量的填料。
This has the advantage that a sufficient reliable coefficient of friction isobtained in each test state of a brake installation, for example of a vehicle,even with a (disk) brake system which is yet run-in. Moreover there is nodownfall of the coefficient of friction by the transition the effect ofthe coating to the run-in state.
這具有的優(yōu)點是,即使對于一個制動系統(tǒng)尚未磨合的車輛,制動片與制動盤間的摩擦系數(shù)基本上與磨合好的摩擦系數(shù)一致。此外,當(dāng)由涂層切換到磨合好的狀態(tài)時,摩擦系數(shù)沒有衰減。
好了,講完了,伙伴們明白了吧?新剎車片剛換上時制動效果差,這個涂層是就是為了提高新剎車片磨合好之前的摩擦系數(shù),使剎車片剛換上就可以得到好的制動效果。
今天剎車片講堂就到這里,歡迎大家關(guān)注,共同學(xué)習(xí)。
