Hydraulic PS fluid CHF 11S 二三事

偷着乐，贪了个小便宜的说

这是一个发生在加拿大的意外，前编在这里：CHF 11S vs Genuine GM Fluid 88901975

够黑！一气订了四瓶，这是要气死亚马逊的节奏吗？

因为财迷啊！四瓶才免邮喔，原本只能买一瓶的这下能整四瓶，还不偷着乐？

验明正身

2014年初换过一次两瓶，现在看来很暴力

今年有了神器看着就温柔多了

先找了个透明塑料杯抽点儿出来看看透明度如何

然后正式开始抽，这么看颜色尚可，抽到底大致是850-900毫升左右

眼看挺黑其实尚可只是颜色有些许变化，本色应该是绿色

还不赖，开几天再换一瓶又可以4-5年无忧矣

这个罐子大致有900毫升的容量，据称液压系统共计有2-3升。

为什么要替换呢？

Bentley says it's "permanently filled"; but most of us would replace the hygroscopic power steering fluid at 30,000 miles.

这个液压系统使用的油液肩负两种功能：方向机液压系统及主动防侧倾液压系统【后者的翻译可能不准确是意译没有去查核】

关于Active Anti-roll摘自Wiki的描述：

Active systems[edit]

The first[4] to use an active anti-roll bar in 1994 was the Citroen Xantia Activa, a medium-sized sedan sold in Europe. The SC.CAR (Systeme Citroën de Contrôle Actif du Roulis) system featured an anti-roll bar that could be stiffened under the command of the suspension ECU during hard cornering. The car rolled at any time at most 2 degrees.

In 2001 the BMW 7 Series (E65) introduced Active Roll Stabilization (ARS) "active" anti-roll bars that can be proportionally controlled automatically by a suspension-control computer, reducing body lean in turns while improving rough-road ride quality.[5]

In 2006 Toyota Active Stabilizer Suspension System. By altering stabilizer bar stiffness, this system acts to reduce body tilt during cornering, keeping the vehicle more level during turns and improving handling, as opposed to the natural tendency of a vehicle to roll due to the lateral forces experienced during high-speed maneuvering. The active stabilizer system relies on vehicle body sensors and electric motors. The first production usage of this system was introduced in August 2005 with the Lexus GS430 sport sedan[6]

Porsche Panamera introduced the same system Porsche Dynamic Chassis Control (PDCC) [7] in 2009.

Mercedes-Benz M-Class#Third generation (W166: 2011–present) introduced a similar system: ACTIVE CURVE SYSTEM in 2011.

Range Rover Sport introduced Dynamic Response active anti-roll bars.

Mercedes-Benz S-Class Active Body Control system uses another approach: the computer uses sensors to detect lateral load, lateral force, and height difference in the suspension strut, then uses hydraulic pressure to raise or lower the spring to counter roll. This system removes the anti-roll bar. Most active roll control systems allow a small degree of roll to give a more natural feel.

Toyota also uses a mechanical system called Kinetic Dynamic Suspension System (KDSS) that essentially disengages the stabilizer bars when off-road, allowing for greater vehicle articulation and ride quality.

两个实际款型的直观演示

这个主动防侧倾液压系统多是前后配备的，言外之意就是有状况的话维修是比较耗时的。

这是一个局部维修的实例

Everything you didn't want to know about your Dynamic Drive but have to….….because you're a DIY'er

不是最后的最后：近年很多车厂都开始使用类似的主动防侧倾设计，有的是使用机械电力控制，当然也有使用液压机械控制的，在这个大家都要节油低扭和享受过弯的时代，车厂只得堆高技术取悦消费者，这也导致DIY'er的空间将被极大的压缩，除了些传统表演项目还是需要苦力，更多的需要电子侦测手段及对车型的原理知识积累才能少走弯路。

发这个帖子的主要目的是为了合并一些相关资料以便备查，无他！
