幼儿园校车制动踏板的检查是通过眼睛和”脚感”共同判断,所谓的制动踏板”脚感”,就是通过驾驶员的脚来判断制动踏板的行程与力度等。具体操作如下所示:
Kindergarten school bus brake pedal check is a common judgment through the eyes and foot feeling ", the so-called brake pedal foot feeling, is to judge by the driver's foot brake pedal stroke and strength, etc. Specific operation as follows:
1、是否有制动?踩下制动踏板,如果发现踏板踩下去软绵绵的,没有明显的阻力,则说明制动系统有故障应进行修理
1, if there is a brake? On the brake pedal, if found on soft pedals, no obvious resistance, show the braking system has a fault should be repaired
2、制动踏板的高度:正常的制动踏板高度,是保证制动踏板踩到底时,制动踏板与驾驶室地板之间还有一定的距离,而且该距离应符合车型的要求。
2, the height of the brake pedal: normal brake pedal height, is the guarantee on the brake pedal, the brake pedal and the cab floor there is a certain distance between, and the distance should be accord with the requirement of cars.
3、自由行程的判断:测量时在制动踏板与驾驶室底板之间立一直尺,测量时在制动踏板与驾驶室底板之间立一直尺,用手向下按制动踏板至有阻力时,记下直尺读数。然后放松踏板,再看直尺读数。两次读数之差即为踏板自由行程。液压制动的踏板自由行程一般在15-20mm,在调整时应按车型规定的数值进行调整。
3, the judgment of free stroke: measurement between the brake pedal and the cab floor stand one ruler, measuring between the brake pedal and the cab floor when erect a ruler, with the hand press brake pedal down to resistance, note down the ruler reading. Then relax pedals, see the ruler reading. The difference between the two readings is the pedal free stroke. Hydraulic brake pedal free stroke generally in 15 to 20 mm, the adjustment should be stipulated in the models of numerical adjustment.
4、制动管内是否有空气?反复踩下制动踏板,观察每次踏板的恢复程度,如果踏板恢复的程度有区别,则说明制动管里有空气,车主要及时到专业维修店里排除制动液压管路中的空气。
4, have air brake pipe? Again and again on the brake pedal, observe the recovery of each pedal, if pedal recovery degree there's a difference, then there is air in the brake pipe, main timely to professional car repair shop air in the brake hydraulic piping.
为了自己和别人的安全,一定要定期检查幼儿园校车制动系统中的制动踏板。
For themselves and others safety, be sure to regularly check the brake pedal in kindergarten school bus braking system.
