第1章一般信息1.1汽车的基本组成今天的一般汽车有15000多个必须相互配合才能工作的单个零件。

这些零件可分为四类：发动机、车身、底盘和电气设备，见图1-1.图1-1 汽车的基本组成发动机用作动力装置，有两种类型：汽油机（也叫做点燃式发动机）和柴油机（也叫做压燃式发动机）。

所有的发动机都有燃料供给系统、排气系统、冷却系统和润滑系统。

汽油机还有点火系统。

点火系统的作用是提供点燃缸内空气-燃油混合气所需要的电火花。

燃料供给系统的作用是存储液态燃料并将其供入发动机。

在化油器内，在进气歧管内或者在气缸内，燃料与空气混合，从而形成可燃混合气。

冷却系统的作用是从发动机上除去多余的热量。

利用空气和冷却液将热量带走。

润滑系统对于保持发动机平稳运转非常重要。

发动机油是润滑系统使用的润滑剂。

1.1.1 车身汽车车身（图1-2）对发动机、乘客和货物起保护作用。

车身的设计应保持乘客安全而舒适。

车身的造型应为车辆一个极具吸引力、鲜艳的、时髦的外表。

车身被制成流线型，以便减小空气阻力，并防止高速时汽车摆动。

图1-2 汽车车身1.1.3 底盘底盘包括传动系统、悬架系统、转向系统和制动系统。

传动系统包括离合器、变速器、传动轴、后桥与差速器以及驱动轮。

离合器或液力变矩器的任务是切断和连接发动机与汽车驱动轮之间的动力传递。

变速器的主要作用是在发动机与驱动轮之间提供一个传动比选择，从而使车辆在所有的行驶条件下都能够满意地工作。

档位的选择可以由驾驶员手动进行，或者靠液压系统自动选择。

传动轴的作用是将动力从变速器传递给后桥-差速器总成的输入轴。

柔性接头允许后桥和后轮上下运动，却不会影响工作。

后桥-差速器总成将发动机旋转动力的传递方向改变90度，从传动轴传到后桥，再到后轮。

它的另一个作用是让每个驱动轮以不同的转速转动。

第三个作用是引入一个传动比，对转矩进行放大。

悬架系统的基本作用是吸收路面凹凸不平所引起的冲击（否则的话，这些冲击将会传递给车辆及其乘客），因此，不管道路条件怎样恶劣，有助于将车辆保持在可控制的笔直的路线上。
