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，但其实手刹失效或未拉到位，由此很容易引发事故。下面来讲讲自上料搅拌车驻车制动的检查方法。

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 number of times of use. Sometimes it is felt that the hand brake has been pulled when operating, but in fact, the hand brake is invalid or not pulled in place, which is very easy to cause accidents. Now let's talk about the inspection method of the parking brake of the self feeding mixer truck.

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 works on the rear wheels. Because the rear wheel brakes have different forms, the parking brake has two working environments: on the rear wheels with drum brakes, the drum brake itself can also act as the parking brake, so when parking, the shoe and friction plate in the brake drum are combined to generate power; On the rear wheel with butterfly brake, there is no brake drum, so an additional parking drum must be installed in the center of the brake disc to complete the parking brake.

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, there are ratchets and pawls inside the parking brake system of the mixer truck. After the handbrake is pulled up, the pawl will be stuck on the ratchet, making the handbrake automatically locked. This is why we hear a "click" sound when we tighten the handbrake 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 connection between the bottom of the hand brake handle and 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 brake effect or sensitivity of the hand brake is not ideal during the inspection, we can solve the problem by adjusting the hand brake operating copper cable.

关于制动系统的检查:每次保养或出长途之前都要对搅拌车制动系统进行检查，内容有：搅拌车制动液液位和油质、管路和接头有没有渗漏、制动片及制动盘的厚度和磨损情况、制动系统真空管路有无泄漏、制动分泵回位情况、驻车制动拉线有无磨损及回位情况等。更多相关内容就来哦我们网站http://www.zkzsljbc.com咨询了解吧！

Check the brake system: check the brake system of the mixer truck before each maintenance or long-distance trip, including the brake fluid level and oil quality of the mixer truck, whether there is leakage in the pipelines and joints, the thickness and wear of the brake pads and brake discs, whether there is leakage in the vacuum pipeline of the brake system, the return of the brake wheel cylinder, whether there is wear and return of the parking brake cable, etc. Come to our website for more information http://www.zkzsljbc.com Ask and understand!
