摘 要
盤(pán)式制動(dòng)器具有重量輕、磨損小、維修方便等優(yōu)點(diǎn)，在汽車(chē)新技術(shù)領(lǐng)域已被廣為關(guān)注。歐美等發(fā)達(dá)國(guó)家和地區(qū)在商用車(chē)及掛車(chē)上已率先采用了盤(pán)式制動(dòng)器。根據(jù)制動(dòng)力的作用不同，盤(pán)式制動(dòng)器分為雙活塞和單活塞兩種結(jié)構(gòu)形式，由于單活塞盤(pán)式制動(dòng)器具有結(jié)構(gòu)緊湊、自重輕和高穩(wěn)定性等優(yōu)勢(shì)，因而更適于在各種重型卡車(chē)、客車(chē)及掛車(chē)上配置。威伯科公司研發(fā)的單活塞盤(pán)式制動(dòng)器，已廣泛使用到MAN、VOLVO、IVECO等著名公司生產(chǎn)的重型車(chē)輛中，并主要在歐、美洲及亞太地區(qū)實(shí)現(xiàn)140多萬(wàn)套的銷(xiāo)量。新型單活塞盤(pán)式制動(dòng)器從傳統(tǒng)的雙活塞盤(pán)式制動(dòng)器結(jié)構(gòu)中的脫穎而出，必將會(huì)成為汽車(chē)盤(pán)式制動(dòng)領(lǐng)域的新寵。
汽車(chē)制動(dòng)系統(tǒng)技術(shù)是由鼓式制動(dòng)系統(tǒng)向盤(pán)式制動(dòng)系統(tǒng)發(fā)展，主要原因是由于盤(pán)式制動(dòng)器與鼓式制動(dòng)器比較有以下優(yōu)點(diǎn)：1、熱穩(wěn)定性好；2、水穩(wěn)定行好；3、制動(dòng)力矩與汽車(chē)運(yùn)動(dòng)方向無(wú)關(guān)；4、易于構(gòu)成雙回路制動(dòng)系統(tǒng)有較高的可靠性和安全性；5、尺寸小，質(zhì)量小，靜熱良好；6、更換襯塊簡(jiǎn)單容易；7、襯塊與制動(dòng)盤(pán)之間的間隙??；8、易于實(shí)現(xiàn)間隙自動(dòng)調(diào)整。
但是，目前在中高級(jí)轎車(chē)上前后輪都已經(jīng)采用盤(pán)式制動(dòng)器。不過(guò)，時(shí)下我們開(kāi)的大部分轎車(chē)（如夏利、富康、捷達(dá)等）。采用還不完全是盤(pán)式制動(dòng)器，而是前盤(pán)后鼓式混合制動(dòng)器，這主要是出于成本上的考慮，同時(shí)也是因?yàn)槠?chē)在緊急制動(dòng)時(shí)，車(chē)身前傾，因此對(duì)前輪制動(dòng)的要求比較大。一般來(lái)說(shuō)，前輪用盤(pán)式就夠用了，但是我們知道高速行駛的轎車(chē)，由于頻繁使用制動(dòng)。制動(dòng)器的摩擦將會(huì)產(chǎn)生大量的熱使制動(dòng)器溫度急劇上升。這些熱如果不能很好散出，就會(huì)大大影響制動(dòng)性能，出現(xiàn)所謂的制動(dòng)效能衰退現(xiàn)象。制動(dòng)器直接關(guān)乎生命，僅從這一點(diǎn)上，就應(yīng)該改進(jìn)正在使用前盤(pán)后鼓混合制動(dòng)器的汽車(chē)。

ABSTRACT
Disc brake with a light weight, wear small, easy maintenance, etc. In the car in the field of new technologies has been widespread concern。Europe and the United States and other developed countries and regions in the commercial vehicle and the trailer has been at the forefront of disc brake。According to the braking force of a different role，Two-piston disc brake and is divided into two single-piston structure，As the single-piston disc brakes with a compact，Light weight and high stability, and other advantages，And therefore more suitable for a variety of heavy-duty trucks、Bus and trailer on the configuration。Wei Boke of research and development of single-piston disc brake，Has been widely used to MAN, VOLVO, IVECO, and other well-known companies in the production of heavy vehicles，And mainly in Europe, the Americas and the Asia-Pacific region to achieve more than 140 million units sold，New single-piston disc brake from the traditional two-piston disc brake in the structure stand out, the car is bound to become a new favorite in the field of disc brake.
Automotive braking systems technology by drum braking system to the development of disc braking system，The main reason is due to brake disc and drum brake has the following advantages compared with：1.、Thermal stability ；2 、water stability of the merciful ；3、brake torque direction of the movement has nothing to do with the car；4、constitutes a two-circuit braking system has high reliability and security；5、small size, the quality of small；6、blocks lining the replacement of simple and easy；7、disc brake lining block with the small gap between the；8、easy to achieve automatic gap adjustment.
But，At present, Qian Houlun in the high-class cars have been used on the disc brake. However, today we have opened most of the car (such as Xiali, Fukang, Jetta, etc.). Is not fully used disc brake. Is not fully used disc brakes, but brake Qianpanhougu mixed, largely because of cost considerations, At the same time, because the car is in the emergency brake, the car forward, the front-wheel brake on the requirements of companies in this sector. In general, front-wheel disc with enough spent ，But we know that a high-speed cars, due to the frequent use of braking. The brake friction will have a lot of heat so that the brake temperature rises rapidly. If they can not shed heat, it will greatly affect the braking performance Will greatly affect the braking performance，The braking performance of the so-called recession.Brake directly related to lifeFrom this point, it should improve Qianpanhougu are using hybrid car brakes.
