摘 要
汽車制動系統(tǒng)是汽車各個系統(tǒng)中最為重要的。如果制動系統(tǒng)失靈，那么結(jié)果將會是毀滅性的。制動器實際上是一個能量轉(zhuǎn)化裝置，這種轉(zhuǎn)化實際上是把汽車的動能轉(zhuǎn)換為汽車的熱能揮發(fā)出去，當(dāng)制動器制動時，驅(qū)動程序來命令十倍于以往的力來使汽車停止下來。制動系統(tǒng)可以發(fā)揮上千磅的壓力來分配給四個制動器。
盤式制動器又稱為碟式制動器，這種制動器散熱快、重量輕、構(gòu)造簡單、調(diào)整方便，特別是高負(fù)載時耐高溫性能好，制動效果穩(wěn)定，而且不怕泥水侵襲，在冬季和惡劣路況下行車，盤式制動比鼓式制動更容易在較短的時間內(nèi)令車停下。有些盤式制動器的制動盤上還開了許多小孔，加速通風(fēng)散熱，提高制動效率。由制動器設(shè)計的一般原則，綜合考慮制動效能、制動效能穩(wěn)定性、制動間隙調(diào)整簡便性、制動器的尺寸和質(zhì)量及噪聲等諸多因素設(shè)計本產(chǎn)品。在設(shè)計中涉及到同步系數(shù)的選取、制動器效能因素的選取、制動力矩的計算，以及制動器主要元件選取，最后對設(shè)計的制動器進(jìn)行校核計算。
關(guān)鍵詞：制動系統(tǒng)，盤式制動器,同步系數(shù)
Abstract
The braking system is the most important system in car. If the brakes fail, the result can be disastrous. brakes are actually energy conversion devices, which convert the kinetic energy of the vehicle into thermal energy .when stepping on the brakes, the drivers commands a stopping force ten times as powerful as the force that puts the car in motion. the braking system can exert thousands of pounds of pressure on each of the four brakes.
The disc brake is called the small dish type brake, this kind of brake radiates quickly, the weight light, the structure simple, the adjustment is convenient, specially when high load the performance is good, applies the brake the effect to be stable, moreover did not fear the spate attack, under the winter and the bad state of roads the driving, the disc type applies the brake compared to the drum type to apply the brake to stop easily in the short time the vehicle. On some disc brake disc has also opened many eyelets, accelerates to ventilate the radiation, enhances the brake efficiency. The principle of the design to the brake system. Synthesize the consideration of the effect to the brake system, the stability of the effect to the brake system, the simple and convenient of the brake cleft adjusting, the size and quantity of the brake system, the same of the brake system and so on to design the product. In this design, adhere to synchronously the coefficient selects by examinations, affect factor selects of the brake system. The calculation of the brake moment, and the selects of the important parts of the brake system , check the whole design at last.
Keywords：brake system , disc brake,Synchronous coefficient
