d*******s 发帖数: 15155 | 2 网上有人做过调查,所有市售RWD车,70%是前面更窄,后面更宽,而赛车相反,70%前
面更宽
Here is a cut from a SAE paper that at least is on of its own.
"When selecting the track width, the front and rear track widths do not
necessarily have to be the same. For example, track width is typically wider
in the front for a rear wheel drive race car. This design concept is used
to increase rear traction during corner exit by reducing the amount of body
roll resisted by the rear tires relative to the front tires [4]. Based on
the corner speeds... 阅读全帖 |

为了marketing和形象的考虑,一些厂家会把本质是前驱车的产品宣传和“包装”成是
后驱车或者是“给大部分人是后驱印象”的四驱车。
发动机纵置,并不表明它是后驱车;
四驱车里面,后轮得到一半或者比一半还要多的动力,也并不表明它是后驱车;
前驱车的一个本质是:发动机100%或者几乎是100%处于前轮轴的前方。此法则对于很多
消费者来讲不容易操作:稍微高档点的车子,发动机舱都塞得满满的,发动机上面还罩
着很多外围零件和盖子,这样真的很难看出发动机本身的具体位置,还有前轮轴的确切
位置。比方说Audi的所有车子,除了R8之外,从4缸一直到12缸发动机,全部车子都是
发动机100%处于前轮轴前方的,相信很多人从外表上根本想象不到。
这里再提供另一个容易操作的识别方法:看前轮间距(Track Width, Front)和后轮间
距(Track Width, Rear)。
后驱布局的车子,除非是... 阅读全帖 |

One that goes unloved a lot: Williams FW15C, the CVT car. Yes, alongside it&
#39;s active suspension, Williams also tried a CVT before it was promptly
disallowed.
Now yes, many people at this point will tune out and yell about parasitic
losses and boringness. However, if you can get your efficiencies near that
of the normal gearbox, you can do quite well with a CVT in racing.
Spectacular even. Th... 阅读全帖 |

c**********d 发帖数: 2428 | 8 Formula SAE, 一种比卡丁车大, 比F-3小的OPEN WHEEL的赛车. 主要是由北美各大学的
学生参加, 目前已经扩展到了全世界. 因为容量关系, 每年只有一百二十到一百四十个
队伍参加. 发动机一般来自摩托车, 比如YAMAHA的YZF600R, HONDA的F4等等. 车身, 悬
挂, 转向还有车壳都由大学学生自己制造. 经费也由自己筹募. 一般来自赞助商和学校
社团的经费.
具体情况可到WWW.SAE.ORG去参看. |
