CHAPTER 5 Steering and suspension system

The suspension covers the arrangement used to connect the wheels to the body. The purpose is to prevent large shocks, caused by the wheels striking bumps in the road, being passed to the vehicle occupants and components; otherwise discomfort and damage would occur.悬架是车架(车身)与车桥(车轮) 悬架是车架(车身)与车桥(车轮)之间一切连接传 力装置的总称。 力装置的总称。其目的是防止车轮遇到路面不平产生 的巨大冲击传给车内的货物和乘客； 的巨大冲击传给车内的货物和乘客；否则会产生不舒 适的感觉和货物的损坏。 适的感觉和货物的损坏。

CHAPTER 5 Steering and suspension system

The suspension system has two subsystems-the front - suspension and the rear suspension. The front suspension is more complicated than the rear suspension. This is because the front wheels must move in several different directions. The wheels must move up and down with the suspension and turn left to right with the steering. Since the car goes in the direction in which the front wheels point, the alignment of the front wheels is important. 悬架系统有两个子系统-前悬架和后悬架. 悬架系统有两个子系统-前悬架和后悬架.前悬架比后悬架 复杂.这是因为前轮需要在不同方向运动. 复杂.这是因为前轮需要在不同方向运动.车轮必须随悬架 上下运动并随转向系统左右转动. 上下运动并随转向系统左右转动.因为汽车在前轮指向的方 向上行驶，所以前轮定位很重要. 向上行驶，所以前轮定位很重要.SEA—Special English for Automobile

Review 2:

What’s the function of Front Wheel Alignment Angles?

Poor alignment can make a car pull to one side and stop the front wheels from returning to the straightahead position after a turn. 不正确的车轮定位参数会使汽车产生偏 驶，阻止车轮在转向后回到直线行驶位 置。SEA—Special English for Automobile

Type of front wheel alignment angles

Camber

前轮倾角Positive camber Negative camber

Camber is the inclination of the wheel relative to the longitudinal vehicle plane, measured in the transverse plane of the vehicle. Positive camber means that the wheels are tilted further out at the top than at the bottom.

CHAPTER 5 Steering and suspension system

Leaf springs are made of long, flat pieces of metal clamped together to form a spring. The spring not only acts as a spring but also locates the axle. To overcome weakness at the mid-point of the main leaf, either the leaf is made thicker at the center or a series of leaves is used. Each leaf is shorter than the one directly above it.钢板弹簧由许多长的金属片夹在一起形成. 钢板弹簧由许多长的金属片夹在一起形成.它不仅做为弹 簧同时用来定位轴.为克服主片中部强度不够的缺点 为克服主片中部强度不够的缺点， 簧同时用来定位轴 为克服主片中部强度不够的缺点，可 以把其中部加厚，或者采用多片钢板。 以把其中部加厚，或者采用多片钢板。每个钢板比它上面 的那个短. 的那个短.SEA—Special English for Automobile

CHAPTER 5 Steering and suspension system

Torsion bars normally connect to the car so that one end is fixed in place and the other attaches to a lever arm. When a force acts on the end of this lever arm, it bends up, causing the torsion bar to twist and absorb the force. When the force is released, the bar untwists to force the lever back to its original position.扭杆弹簧一端固定在汽车上的适当位置， 扭 …… 此处隐藏：3700字，全部文档内容请下载后查看。喜欢就下载吧 ……
