在車輛的配置中，剎車主要是在面對突發(fā)狀況的時候能夠保證掌控其安全，對于
水泥自上料攪拌車這種專用車輛來說，就顯得特別的重要。基本的剎車應(yīng)該具備以下幾點。
In the configuration of the vehicle, the brake is mainly to ensure the safety of the vehicle in the face of emergencies. It is particularly important for the special vehicle such as cement self loading mixer. The basic brake should have the following points.
一、要具有合適的摩擦系數(shù)。摩擦系數(shù)是摩擦材料的基本參數(shù)，決定基本的剎車片制動力矩。國標(biāo)就嚴(yán)格要求制造商必須在包裝上注明摩擦系數(shù)。摩擦系數(shù)必須適當(dāng)，太高會造成制動過程中的車輪抱死、方向失控和燒片，太低則制動距離過長。
1、 The friction coefficient shall be appropriate. Friction coefficient is the basic parameter of friction material, which determines the basic braking torque of brake pad. The national standard strictly requires the manufacturer to indicate the friction coefficient on the package. The friction coefficient must be appropriate. If the friction coefficient is too high, the wheel will be locked, the direction will be out of control and the disc will be burnt. If the friction coefficient is too low, the braking distance will be too long.
二、使用壽命要符合標(biāo)準(zhǔn)。使用壽命是大家普遍關(guān)注的產(chǎn)品指標(biāo)。通常剎車片能保證3萬公里的使用壽命。像剎車片材料中采用的大顆粒石墨和黃銅還能夠減少對剎車盤的磨損。
2、 The service life shall meet the standard. Service life is a product index that is widely concerned by everyone. Usually, the brake pad can guarantee the service life of 30000 km. Large grain graphite and brass used in brake pad materials can also reduce the wear of brake discs.
三、舒適度問題。小型攪拌車舒適性性能的直接體現(xiàn)，包括制動感覺、噪音、粉塵、冒煙、異味等。隨著私家車的增多和人們生活水平的提高，在滿足安全的基本前提下，舒適性越來越成為摩擦片的重要指標(biāo)。
3、 Comfort. The direct embodiment of the comfort performance of small-scale mixer, including braking feeling, noise, dust, smoke, odor, etc. With the increase of private cars and the improvement of people's living standards, comfort has become an important indicator of friction plates under the basic premise of safety.
四、安全性能要可靠。攪拌車剎車片在制動時會產(chǎn)生瞬時的高溫，尤其在高速行駛或緊急制動時。在高溫狀態(tài)下，摩擦片的摩擦系數(shù)會下降，稱為熱衰退性。熱衰退性的高低決定高溫狀態(tài)和緊急制動時的安全。
4、 The safety performance shall be reliable. The brake pad of the mixer truck will produce instantaneous high temperature during braking, especially during high-speed driving or emergency braking. At high temperature, the friction coefficient of the friction plate will decrease, which is called thermal degradation. The degree of thermal decay determines the safety of high temperature and emergency braking.
If there is a problem with the brake of the mixer truck, it must be replaced in time, and more attention should be paid to the selection. For more related matters, please visit our website http://www.top2010.cn Consult and understand!
