制動器畢業(yè)設(shè)計外文翻譯-其他專業(yè)(完整版)
【正文】 年代的汽車制造商都重新作為 新型 ）。 盤式制動器一些背景。后沿的制動蹄片與制動鼓幾乎沒有接觸。當(dāng)松開剎車， 回位彈簧從制動鼓的表面拉回剎車片。 鼓式制動器 單前沿 下一個，更加復(fù)雜的類型的制動是鼓式制動器。他們是如何不同的設(shè)計產(chǎn)生了摩擦的。這個工作最好的說明，設(shè)想一種紡紗鋼軸上的閥瓣在你的面前。但在路上的車，最終會導(dǎo)致剎車轉(zhuǎn)子失靈的，不是你能想象的。 從左至右。 整個的理解能量轉(zhuǎn)換的關(guān)鍵是，剎車他們該做什么 ,以及為什么它們設(shè)計成這樣。 猶由于新的剎車墊合成，襯墊的熱傳遞到卡鉗一旦轉(zhuǎn)子太熱了，制動液開始 沸騰冒泡 。由于氣體之間不能待在墊層及轉(zhuǎn)子，而是形成薄薄的一層在兩個之間準(zhǔn)備排走。 因為在盤式制動器的剎車片和轉(zhuǎn)子的位置，摩擦產(chǎn)生的 接觸 點的位置也產(chǎn)生了一個機械的抵御轉(zhuǎn)子的回轉(zhuǎn)運動。制動系統(tǒng)本質(zhì)上是改變能量的類型。 復(fù)雜的說： 制動器被用來讓你的車減速，但可能不是你所想的意思。也是就說：能量不能被 創(chuàng)造也不能被消滅，只能由一種形式轉(zhuǎn)換成另一種。但是如果你持續(xù)使用他們， 轉(zhuǎn)子或鼓留 熱 并沒有機會冷卻 。這種類型的制動失效在舊車輛更 常見。無論如何你最終獲得 交叉鉆孔 或溝槽剎車盤。 如果制動轉(zhuǎn)子是一個單一的鋼鐵鑄塊，這將有嚴(yán)重的散熱性能和氣化氣無法排去 。 重要的一點：鉆孔轉(zhuǎn)子通常只使用于賽車。更多的物質(zhì)也意味著更大的表面積，墊片產(chǎn)生摩擦 ,和更好的散熱。 不同類型的制動器。 橡膠產(chǎn)生摩擦，產(chǎn)生熱量，這是動能轉(zhuǎn)移使車慢下來。下面的例子顯示了一個簡單的模型。此圖 （右側(cè)） 顯示當(dāng)剎車時，會發(fā)生什么情況。所以每個剎車片現(xiàn)在有一個前沿的和一個后沿。在美國汽車創(chuàng)始人克羅斯利發(fā)明了我們目前熟知和喜愛的快車，就是 使用了很多類似的盤動制動器和卡鉗。s the First Law of Thermodynamics, sometimes known as the law of conservation of energy. This states that energy cannot be created nor destroyed, it can only be converted from one form to another. In the case of brakes, it is converted from kiic energy to thermal energy. Angular force. Because of the configuration of the brake pads and rotor in a disc brake, the location of the point of contact where the friction is generated also provides a mechanical moment to resist the turning motion of the rotor. Thermodynamics, brake fade and drilled rotors. If you ride a motorbike or drive a race car, you39。suck39。s going on, the rest of this page is going to cause you a bit of a headache. Drum brakes single leading edge The next, more plicated type of brake is a drum brake. The concept here is simple. Two semicircular brake shoes sit insid e a spinning drum which is attached to the wheel. When you apply the brakes, the shoes are expanded outwards to press against the inside of the drum. This creates friction, which creates heat, which transfers kiic energy, which slows you down. The example below shows a simple model. The actuator in this case is the blue elliptical object. As that is twisted, it forces against the brake shoes and in turn forces them to expand outwards. The return spring is what pulls the shoes back away from the surface of the brake drum when the brakes are released. See the later section for more information on actuator types. The single leading edge refers to the number of parts of the brake shoe which actually contact the spinning drum. Because the brake shoe pivots at one end, simple geometry means that the entire brake pad cannot contact the brake drum. The leading edge is the term given to the part of the brake pad which does contact the drum, and in the case of a single leading edge system, it39。ll find disc brakes on the front of almost every car and motorbike built today. Sportier vehicles with higher speeds need better brakes to slow them down, so you39。s really difficult to stop a vehicle rolling backwards if it39。t a problem the brakes are changed after each race or weekend. But on a road car, this can eventually lead to brake rotor failure not what you want. I only mention this because of a lot of performance suppliers will supply you with drilled rotors for street ca
