自動攪拌車停車的時候無論是在平地上還是在斜坡上都必須使用駐車制動，駐車制動簡稱手剎，手剎的使用效果會隨著使用次數(shù)的增加而下降，有時候在操作的時候覺得手剎已經(jīng)拉上了，但其實(shí)由于手剎失效或未拉到位而引發(fā)事故，因此，駐車制動的保養(yǎng)也是十分重要的。

When the automatic mixer truck stops, it must use the parking brake whether on the flat ground or on the slope. The parking brake is referred to as the hand brake for short. The use effect of the hand brake will decline with the increase of the use times. Sometimes when operating, it feels that the hand brake has been pulled, but in fact, accidents are caused by the failure or failure of the hand brake. Therefore, the maintenance of the parking brake is also very important.

攪拌車的駐車制動系統(tǒng)是作用在后輪上的，而因為后輪制動器的形式不同，駐車制動有兩種工作環(huán)境：在安裝鼓式制動器的后輪上，由于鼓式制動器本身就可以兼做駐車制動器，因此在駐車時剎車鼓內(nèi)的蹄片和摩擦片相結(jié)合，這樣就可以產(chǎn)生動力；而在安裝蝶式制動器的后輪上，由于沒有剎車鼓，因此就必須在剎車碟片的中心部位安裝額外的駐車鼓來是駐車制動完成制動工作。

The parking brake system of the mixer truck acts on the rear wheels, and because the rear wheel brakes have different forms, the parking brake has two working environments: on the rear wheels with drum brakes, because the drum brakes themselves can also act as parking brakes, when parking, the shoes and friction plates in the brake drum are combined, which can generate power; On the rear wheel with butterfly brake, there is no brake drum, so additional parking drum must be installed in the center of the brake disc to complete the braking work.

準(zhǔn)確的說，就是攪拌車的駐車制動系統(tǒng)的內(nèi)部裝有棘輪和棘爪，在將手剎拉起后，棘爪就會卡在棘輪上，使手剎自動鎖緊，這也就是我們在拉緊手剎手柄的同時會聽到“咔嗒”聲響的原因。

To be exact, the parking brake system of the mixer truck is equipped with ratchets and pawls. After the hand brake is pulled up, the pawls will be stuck on the ratchet, making the hand brake lock automatically. This is the reason why we can hear the "click" sound when tightening the hand brake handle.

在手剎手柄的底部和銅纜的連接處有一個可調(diào)的補(bǔ)償機(jī)構(gòu)，使用扳手松開鎖緊的螺帽，就可以拉伸剎車銅纜的長度，如果在檢查中，我們發(fā)現(xiàn)手剎的制動效果或靈敏度不理想，那就可以通過調(diào)節(jié)這個手剎操作銅纜來問題。

There is an adjustable compensation mechanism at the bottom of the handbrake handle and the connection of the copper cable. Use a wrench to loosen the locked nut to stretch the length of the brake copper cable. If we find that the braking effect or sensitivity of the handbrake is not ideal during the inspection, we can solve the problem by adjusting the handbrake operating copper cable.

手剎失靈造成事故的現(xiàn)象屢見不鮮，不僅僅是攪拌車，其它車輛，比如乘用車、隨車吊、清障等等剎車失靈都容易造成事故，各位卡友們一定要經(jīng)常檢查自己愛車的手剎，發(fā)現(xiàn)問題，及時處理。更多相關(guān)內(nèi)容就來網(wǎng)站http://kitchinit.com關(guān)注咨詢吧。

Accidents caused by handbrake failure are common, not only for mixing cars, but also for other vehicles, such as passenger cars, truck cranes, obstacle removal, etc. brake failure is easy to cause accidents. Card friends must always check their car handbrakes, find problems, and deal with them in time. Come to the website for more relevant content http://kitchinit.com Pay attention to consultation.
