    行车制动器是用在行车上做刹车用的,对于它的使用是如何运行的呢?下面根据行车制动器的运行机构做下说明:

    行(xing)车(che)制动(dong)(dong)(dong)(dong)器的(de)(de)(de)运行(xing)机(ji)(ji)构(gou)根据(ju)制动(dong)(dong)(dong)(dong)力(li)(li)(li)(li)源的(de)(de)(de)不同(tong),可分(fen)为简单(dan)(dan)制动(dong)(dong)(dong)(dong)、动(dong)(dong)(dong)(dong)力(li)(li)(li)(li)制动(dong)(dong)(dong)(dong)和伺服(fu)制动(dong)(dong)(dong)(dong)三(san)大类。简单(dan)(dan)制动(dong)(dong)(dong)(dong)又称人力(li)(li)(li)(li)制动(dong)(dong)(dong)(dong),可分(fen)为机(ji)(ji)械式和液压(ya)式两种,这类制动(dong)(dong)(dong)(dong)器的(de)(de)(de)驭(yu)动(dong)(dong)(dong)(dong)机(ji)(ji)构(gou)虽然有其优点(dian)(dian),曾被用在老式汽车(che)、轻型(xing)及(ji)部分(fen)小(xiao)型(xing)汽车(che)上,但由于(yu)用人力(li)(li)(li)(li)作为制动(dong)(dong)(dong)(dong)力(li)(li)(li)(li)源及(ji)其他一些缺点(dian)(dian),所(suo)以机(ji)(ji)械式驱动(dong)(dong)(dong)(dong)机(ji)(ji)构(gou)已不用于(yu)行(xing)车(che)制动(dong)(dong)(dong)(dong),而液压(ya)制动(dong)(dong)(dong)(dong)也逐(zhu)渐被不同(tong)型(xing)式的(de)(de)(de)动(dong)(dong)(dong)(dong)力(li)(li)(li)(li)驱动(dong)(dong)(dong)(dong)机(ji)(ji)构(gou)和伺服(fu)驭(yu)动(dong)(dong)(dong)(dong)机(ji)(ji)构(gou)所(suo)取代。尤其对于(yu)载重汽车(che)来说(shuo)更是如此(ci),大部分(fen)是采(cai)用动(dong)(dong)(dong)(dong)力(li)(li)(li)(li)制动(dong)(dong)(dong)(dong),个别车(che)型(xing)采(cai)用伺服(fu)驱动(dong)(dong)(dong)(dong)机(ji)(ji)构(gou)。

    行车制动器的动力制动是利用由发动机将其动力转化为空气或油液的势能,来作为汽车制动的全部力源,所以驾驶员加干制动踏板上的力,只是起控制回路中控制元件的作用。由于踏板力较小,且有适当的踏板行程,所以减轻了驾驶员的疲劳,且控制灵活。

    行(xing)车制动(dong)(dong)器的动(dong)(dong)力(li)制动(dong)(dong)可分(fen)为(wei)(wei)气压(ya)制动(dong)(dong)、气顶液(ye)制动(dong)(dong)和全液(ye)压(ya)动(dong)(dong)力(li)制动(dong)(dong)等型式。载重汽车中以(yi)气压(ya)制动(dong)(dong)为(wei)(wei)多数(shu),气顶液(ye)动(dong)(dong)力(li)制动(dong)(dong)次之。全液(ye)压(ya)动(dong)(dong)力(li)制动(dong)(dong)目(mu)前还很(hen)少见,不(bu)过,当需要整车液(ye)压(ya)化(hua)的时(shi)候,连同防抱死装(zhuang)置一起将会得(de)到发展。

    行车(che)(che)制动器的(de)运(yun)行机(ji)构的(de)有效(xiao)运(yun)行保障(zhang)了行车(che)(che)的(de)使(shi)用(yong)安全(quan),是行车(che)(che)部件的(de)必要使(shi)用(yong)装(zhuang)置。
