自动搅拌车停车的时候无论是在平地上还是在斜坡上都必须使用驻车制动，驻车制动简称手刹，手刹的使用效果会随着使用次数的增加而下降，有时候在操作的时候觉得手刹已经拉上了，但其实由于手刹失效或未拉到位而引发事故，因此，驻车制动的保养也是十分重要的。

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.

搅拌车的驻车制动系统是作用在后轮上的，而因为后轮制动器的形式不同，驻车制动有两种工作环境：在安装鼓式制动器的后轮上，由于鼓式制动器本身就可以兼做驻车制动器，因此在驻车时刹车鼓内的蹄片和摩擦片相结合，这样就可以产生动力；而在安装蝶式制动器的后轮上，由于没有刹车鼓，因此就必须在刹车碟片的中心部位安装额外的驻车鼓来是驻车制动完成制动工作。

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.

准确的说，就是搅拌车的驻车制动系统的内部装有棘轮和棘爪，在将手刹拉起后，棘爪就会卡在棘轮上，使手刹自动锁紧，这也就是我们在拉紧手刹手柄的同时会听到“咔嗒”声响的原因。

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.

在手刹手柄的底部和铜缆的连接处有一个可调的补偿机构，使用扳手松开锁紧的螺帽，就可以拉伸刹车铜缆的长度，如果在检查中，我们发现手刹的制动效果或灵敏度不理想，那就可以通过调节这个手刹操作铜缆来问题。

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.

手刹失灵造成事故的现象屡见不鲜，不仅仅是搅拌车，其它车辆，比如乘用车、随车吊、清障等等刹车失灵都容易造成事故，各位卡友们一定要经常检查自己爱车的手刹，发现问题，及时处理。更多相关内容就来网站http://www.jfhntjbj.com关注咨询吧。

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://www.jfhntjbj.com Pay attention to consultation.
