英语段落翻译

  在汽车设计时为使转向车轮具有转向轻便、准确和行驶稳定等特性,在转向车轮上设计有主销内倾角、主销后倾角、车轮外倾角和车轮前束等四项参数,统称为前轮定位。它是一组把转向轮安装成一定的静态几何角度和尺寸的参数值。在这四参数中前两项是由汽车的基础件来保证的,一般不会有较大变化。车辆在使用中由于车架、车轴、转向机构的变形与磨造成损改变了原有的参数值,致使前轮定位失准(主要是外倾角和前束),车辆行驶时转向轮在向前滚动的同时还将产生横向滑移,这就是我们所说的侧滑。侧滑试验台主要用于测量由于车轮外倾角和前束共同作用而形成的侧滑量。只有前束而无车轮外倾角的车辆通过侧滑台
  时侧滑板向外滑移;只有车轮外倾角而无前束的车辆通过侧滑台时侧滑板向内滑移。侧滑量定义的单位是m/km,含义是汽车正直向前行进1000m而造成滑动板位移1m,即为一个基本侧滑单位1m/1km。侧滑台实际上是将1000m精密缩小1000或2000倍的特殊(可左右位移)路面,例如:侧滑板有效长度为1000mm(相当于将1000m缩小了1000倍),汽车前轮正直行过侧滑板时使得侧滑板向垂直于汽车前进方向的方向位移了1mm,我们说这台车的侧滑量是1mm/m,若将此值的分子分母同乘以1000,就将其化为标准侧滑量1m/km了。
侧滑板移动的方向是由车轮的侧滑方向来决定的,若前轮外倾角产生的侧滑占主导地位,侧滑板是向内移动的;反之,若前束产生的侧滑占主导地位,则侧滑板向外移动。因此,侧滑试验台测量出的值即有方向又有量值。

   由上可见侧滑实验台就是由两块尺寸精密、左右可滑动的侧滑板加位移传感器构成的了。为了减小滑板滑动阻力,在两块滑板下的四角装有滚动轴承。

Designed to make the car steering wheel with shift light, accurate and stable driving characteristics, the steering wheel on the design of Kingpin Inclination, Caster, wheel camber and toe the four parameters of the wheel, collectively referred to as pre - wheel alignment. It is a group of the steering wheel to install into a certain amount of static geometry and size of the parameter values. In these four parameters in the first two basic parts from the car to ensure that, generally there will be no significant change. Vehicles in use due to the frame, axles, steering body deformation and wear damage caused by changes in the original parameter values, resulting in inaccurate positioning front (mainly camber and toe), vehicles traveling in the forward steering wheel rolling at the same time will result in lateral slip, and this is what we call spin. Sideslip test stand is mainly used to measure due to the wheel camber and toe together to form the amount of skidding. Only the first beam without the wheel camber vehicles skidding Taiwan 
  Slip out when the sliding plate; only the wheel camber and no toe of vehicles sliding table and sliding board sliding inwards. Sideslip quantity units defined by m / km, meaning the vehicle upright and moved forward 1000m displacement caused by sliding panels 1m, namely, a basic sliding unit 1m/1km. Yaw Taiwan is actually 1000m precision will reduce the 1000 or 2000 times the special (can be left displacement) the road surface, such as: sliding board effective length 1000mm (equivalent to 1000m reduced 1000-fold), automobile front wheel skid plate too upright row makes the sliding plate when the direction perpendicular to the direction of vehicle displacement of 1mm, we say that this sets the amount of cars skidding is 1mm / m, if this value is multiplied by 1000 with the numerator and denominator, it will translate into standards of sideslip the amount of 1m/km of. 
Sideslip direction of plate movement is to determine the direction of the wheel spin, if the front wheel camber generated by sideslip dominant sliding board is moved inward; the other hand, if the pre-sliding beam produced by dominant skid plates are moving outward. Therefore, the yaw test bed to measure the value that is the direction of another value. 

   It is clear from sliding bench is the size of precision by the two left and right sliding sliding plate and composition of the displacement sensor. In order to reduce the skateboard sliding resistance, two skateboards with rolling under the four corners.
