1、结构不同:汽车碟刹的制动器是由制动盘、制动钳、摩擦片、分泵、油管等部分组成。汽车鼓刹的鼓式制动器主要包括制动轮缸、制动蹄、制动鼓、摩擦片、回位弹簧等部分。

2、工作原理不同:汽车碟刹是制动钳与随车轮转动的制动盘发生摩擦,达到制动的目的。汽车鼓刹主要是通过液压装置使摩擦片与随车轮转动的制动鼓内侧面发生摩擦,从而制动。
3、造价不同:鼓式制动器比较便宜,一般用于制造成本较低的车型。
1、碟刹和普通刹车重量不同:
一般来说,低价位的碟刹车要比V刹车车重800g到1kg左右,高档车差距 要小些。重量对于骑行还是有影响的;
2、碟刹和普通刹车制动效果不同:
V刹一般制动效果还是很强劲,但在高速下坡,持续刹车时,由于摩擦,车圈温度越高,刹车效果也随之下降,另外雨水天气和恶劣路况(泥浆较多)时,V刹效果也会有一定影响;
碟刹特点是不受雨水天气和恶劣路况的影响, 因为碟刹盘片是钢制的,而且一般带孔,在持续下坡刹车过程中随着热量增加的衰减也比V刹车要好些;

扩展资料:
鼓刹,它与轮胎固定并以同样的速度转动,刹车的时候通过刹车片和轮胎之间产生的摩擦力能使轮胎会很快停下转动,达到刹车的目的。也是基于这种原理,所以大都会安装在汽车的后轮。也许你听了会说鼓刹好呀,刹车快。
其实鼓刹也是有缺点的,因为与轮胎固定,所以如果连续踩刹车会使刹车片产生高温而发生热衰退的情况,同时它的单点刹车的力度也不受控制。碟刹,它又叫做盘式刹车,同时它也分为普通和通风盘式刹车两种。
这里主要说通风盘式刹车,它的优点是作用灵敏,散热良好,适合连续踩刹车,这点和鼓刹相反。因为符合制动防抱死系统,所以在刹车的时候能迅速制动,又因为存在风孔,所以能利用自然风达到散热的功能,现在已经被大量用在了汽车的前轮。
现在更有一些高级车会在四个轮子上都装置碟刹,以确保安全性和散热。碟刹的广泛应用也是汽车制造提升的一个重要发展过程,毕竟汽车的安全性能提升是驾驶员不能忽视的问题。但是碟刹也不是百分百发挥性能的,需要经过正确的磨合才行。

碟式刹车(DiscBrakes),有一个与轮胎固定并同速转动之圆碟片,刹车时运用油压推动刹车片夹紧圆碟,藉由接触产生之磨擦力来抑制轮胎的转动,以达成刹车之目的。
而鼓式刹车(DrumBrakes)也即有一形状类似铃鼓的铸铁件,称为刹车鼓(Brakedrum)与轮胎固定并同速转动。刹车时运用油压推动刹车靴(BrakeShoes)接触刹车鼓内缘,藉由接触产生的磨擦力来抑制轮胎之转动以达成刹车之目的。
一般而言,碟式刹车具有较佳的反应性及稳定性,散热性较佳,迫力皮更换简便等优点。但因其磨耗率较高,同时整体成本较高。
现在的车子,最常见的配置是前轮用碟式,后轮鼓式,或者4轮全用碟式刹车居多。
如果你买了一辆二手车为安全起见,一般人都会再花钱换刹车皮,许多人忽略了替刹车碟和刹车鼓翻新。残旧的刹车碟和刹车鼓若出现了像唱片一般的坑纹,就会大大降低刹车的效能,单靠全新的刹车皮提高刹车性能,没有多大的作用。
简单的说就是刹车碟是在刹车的时候在碟上挤压一个力,使车辆制动/鼓式刹车是用液压使鼓内膨胀,使车辆制动。也就是说,一个是外面的摩擦,一个是里面的摩擦。
