制(zhi)动器知识

行车制动器和发动机制动器的区别是什么

来源:http://impnow.com/news/225.html添加时间:2016-02-02

    行车制动器和发动机制动器有什么区别呢,行车制动时车辆的刹车系统是叫做行车制动,发动机制动时通过变速箱和发动机曲轴活塞相连的部分制动叫做发动机制动。一般在货车上面使用的发动机制动比较多。轿车的话在停车后挂入空挡就是利用了发动机制动。

    行(xing)车(che)制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)就是脚刹,和(he)驻车(che)制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)属(shu)(shu)于******制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)系统(tong)。发动(dong)(dong)(dong)(dong)(dong)机(ji)制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)属(shu)(shu)于辅(fu)助制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)(实际是持续制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)),属(shu)(shu)于车(che)辆的第三制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)系统(tong),再(zai)需要长时间使(shi)(shi)用制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)器的时候(hou)使(shi)(shi)用(比如下(xia)长坡时),也可和(he)行(xing)车(che)制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)同时作用,以减轻(qing)行(xing)车(che)制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong)的负(fu)担,延(yan)长摩擦片的使(shi)(shi)用寿命。另(ling)外还有发动(dong)(dong)(dong)(dong)(dong)机(ji)排(pai)气制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong),缓速器(电涡流,液力)也属(shu)(shu)于辅(fu)助制(zhi)(zhi)(zhi)(zhi)动(dong)(dong)(dong)(dong)(dong),国标没有强制(zhi)(zhi)(zhi)(zhi)使(shi)(shi)用,但现在大(da)客车(che)要评定等级必须有。

    行车制动器指脚刹,发动机制动器有发动机缓速制动和发动机排气制动。行车制动是用脚刹强制制动,发动机制动是靠发动机转速控制车速制动。
