刹车真空泵,也叫刹车助力泵,是在制动过程中,控制进入助力泵的真空,使膜片移动,并通过联运装置利用膜片上的推杆协助人力去踩动和推动制动踏板,从而对驾驶员踩踏板的力产生放大的效果


刹车真空泵漏气的表现

我们可以通过一个小实验进行验证,打开发动机,运行1~2分钟后关闭,然后分三次踩踏板。正常工作的真空助力器踩第一脚时,由于真空助力器存在足够真空,其踏板行程正常;第二脚,由于助力器内已损失一些真空,所以踏板行程会减小很多;待踏第三脚时,真空助力器内真空已很少,所以踏板行程也很少,再踏下去就踏不动了

以上即所谓“一脚比一脚高”,这证明助力器无漏气,工作正常,如果每一脚踏板行程都很小,且行程都不变,即所谓的“脚特别硬”,则说明助力器漏气失效。漏气严重的,可听到漏气声音,对于漏气的助力器需予以更换

刹车真空泵坏了的其它表现

1、刹车性能差或或无刹车效果

2、从外观可看到真空泵外连接处有漏油现象

3、刹车踏板回位慢或不回位

4、踩下制动踏板后能听到明显的异响

5、刹车时,方向跑偏或抖动
