我网上查了下,包括基本的动力系统,也是维修最贵的部分。貌似别的东西就是修理基

是不是有了drivetrain warranty,就不用太担心动力系统的问题。只要test drive感

c******s 发帖数: 197 | 3 就我所知ICE的效率也就是30%左右,无论用什么hybrid drivetrain, series, paral
le 或是 combined drivetrain,能量总来自于fuel,如果ICE始终运行在最高效率工作
点,drivetrain最高效率就是30%×95%(电机的效率),减去车子上面ac, power st
eering 和其他utility的消耗,折算下来就算是28%的fuel efficiency吧,hybrid我觉
得只是一个改进的比较高效利用燃油的方式。ICE我不大了解,是不是30%效率工作的时

油门一放,假设有离合轮子跟drivetrain分开,那么能量消耗在
克服空气阻力和克服轮子车体间的滑动摩擦。
如果drivetrain不分开,那么还要克服带动发动机的阻力。机车
现在都是电机驱动(包括内燃机车),也就是要把车动能转成电能。
跟hybrid car减速时一样。 |

In D5, your shift points should be 1,2,3,4,5, then another slight RPM drop
where the torque converter mechanically locks to the drivetrain (that's
where the rumble happens). Prior to that final lockup, it is only
hydraulically connected to the drivetrain which is slightly less efficient.

前两天看了一些贴子,其中有许多有关车和车,日本品牌和美国品牌,欧洲品牌车的争
论和比较。发现其中许多对比和比较很盲目。很多不具有可比价性,比如说Car 和SUV
那个安全。发现很多人同我以前刚来U.S.时一样, 对车的认识大多都停留在表面上。
在选车对比之前,我想大家应该对不同的车有个大概的了解。这也是我写此文的目的。
希望对于刚来美国并准备选车的人,能有所启发和期到拓展视野的作用。首先声明,本
人未在任何和汽车有关的行业工作,仅出于个人爱好。有不完善之处,希望各位参与讨
论并给于补充。
初到北美时,除了对国内的夏利,桑塔那VW, Audi, Toyota,Cherokee等有点印象外(
当然还有BMW, BENZ等,不过没有机会尝试)。对其它种类的车毫无了解。和很多人一
样,别人讲那一种车好, 自己于是就认为它好;别人说那种车不好, 知己也认为它不
好。 后来才发现其实自己对北美的汽车行业和市场完全缺乏认知。第一天走在大街上

g****r 发帖数: 636 | 38 首先我来说下我现在升档的方法
踩离合,等转速降,降到合适的转速松离合给油
但是现在有些问题,电子油门的车有时候由于ECU的干扰,转速降的会比较慢,1-2的时
候rev hang比较严重,2-3的时候有时候也有rev hang,所以用这个方法换档等待的时
间比较长
然后我注意到,如果不等转速降就松离合的话,转速就直接被拉到了下一档的转速上
而且没有jerky的感觉,drivetrain 也没有shock,发动机的转速降的特别的轻松
搜了下油管,发现这位也好像是直接抬的离合
http://www.youtube.com/watch?v=96ekbvjyr0g
理论上说这样应该对drivetrain或者clutch有磨损的对不对?(以前开坏过一个
transfer case可能是因为这样开)
想请问这样做真的OK么?大家都是怎么升档的?等转速match还是直接抬离合?

来源: 汽车商业评论 发布时间: 2009年12月10日 14:39 作者: 刘杨
感觉良好的ZENN公司与宣称拥有超级电容技术的EEStor公司,通过技术建立合作,
试图打造出一个能够改变世界的产品,但困难重重。
2009年9月,加拿大电动车制造商ZENN宣布放弃之前的战略,不再量产可以在高速
公路上行驶的纯电动汽车。而去年此时,他们正与加拿大政府对簿公堂,为这类电动车
争取上高速公路的权利。
这是ZENN创办以来战略调整最大的一次。ZENN公司创办者、CEO安·克利福德
(Ian Clifford)说:"2008年,电动汽车产业发生了巨大的变化,我觉得我们的业务
模式不应该局限于销售和生产电动车。"新计划是,未来ZENN不再进行电动车量产的开
发工作,而是与更多的主机厂联系,推广自己的电动动力总成技术--ZENNergy,以超级
电容EESU为核心动力。《汽车商业评论》认为,这是一个令人有些沮丧的局面。
ZENN的意思是"零排放,无噪音(Zero Emission,Non Noise)"。这种表达方

f*********e 发帖数: 487 | 41 Im in the market for a new SUV and being that these bike gangs are out there
, can anyone recommend an SUV that can run over motorcycles and their
operators in case they try to box me in or attack me and my family.
I need a vehicle that won't get damaged as it rolls over crunching metal and
bones. Something with enough clearance so the drivetrain and muffler don't
get damaged. And I would also need tires that you can continue to drive on
even after they are slashed.

well, you can't say which one is absolutely better than another one.
the advantage of FWD: lower cost to build, weight is over drive wheels.
the advantage of RWD: weight shifts to drive wheels on acceleration, steering
is better. drivetrain doesn't load the steering wheels. |

AR 发帖数: 436 | 44 在机械和液态传动不同的基本上,两种transmission的gear ratio
设计也有不同,比如5-speed manual的automatic transmission的
counterpart往往就只有4-speed的gears. 举个具体的例子:

Drivetrain GL 2.0L GL
Transmission Gear Ratio
Manual Automatic

2nd 2.12:1 1.55:1

的人具有各自不同的认识和需要。另外,不同的车有不同的优缺点,一款车的优点针对
不同的人可能变成了缺点。本人在写的时候尽力争取做到不Judgmental。有网友问为什
么没有Sedan?查了一下原文,好象在Car的4-door里面漏掉了。很高兴大家能够一起讨

另外,在北美,汽车厂的商业宣称和任何行业的广告一样,只宣传其优点,针对弱点不
会讲实话,也不会讲假话,爱打搽边球。宣传上有时让人产生混淆,有时连车商自己都

前面的内容仅涉及到对家用汽车的一些简单的概念。有网友觉得对动力驱动系统(
Drivetrain)的概念不好理解,特别是4WD和AWD有些分不清。我们可以简单的从头分析
一下,早期的汽车多是后面两轮驱动RWD(Rear Wheel drive)的。由于Car的底盘较低
,对设计和制造而言没有前面的两轮驱动FWD(Front wheel drive)来得容易。由于 |

M**********n 发帖数: 25 | 46 对于09年的车,现在看来似乎在recall之后floor mat的问题解决了。
不知有没有这个年份的车被recall之后换了gas pedal呢? 我朋友的车是没有。
所以如果万分不幸遇到后面这个问题,如下对付:
1. brake就不要用啦~用了反而会侧翻前滚翻……反正就是翻;
2. key也不要拔。您肯定不想steering系统再来点变态行为;
3. N 档挂上=)于是engine和drivetrain就会分离啦。youtube上有示范。
官方的两次recall要是都做了的话,感觉好像还蛮放心的。
看了一下午lexus gas pedal事件的911电话录音video,挺难受的。
希望不管开什么车的人都能避免这种事情。 |
