奇怪,看不到LZ 50楼的更新

还没正式更新。我希望写详细一些，让斑竹加精。
简单说两句，bilstein 5100前避震筒有四个卡环作为弹簧支撑点。我第一次安装选择了最低档（称为原车位）。但是LC150原车弹簧比LC120原车弹簧短3厘米，而bilstein5100是按照LC120代设计的。因此安装后，实际LC150弹簧没有任何pre-loading负重，因此特别松散，导致转弯侧倾加剧。
我第二次重新让改装店把卡环设置到第二档，弹簧装到避震筒以后完全没有free play自由行程。前轮轴心到轮眉上升到55厘米、（相比之下后轮轴心到轮眉56厘米）
装车如今已经三天，质的飞跃
1. 进地下停车场的下坡搓板路依然远远比原厂避震筒安静
2. 转弯侧倾远远低于第一次安装bilstein5100的错误档位
3. 高速非常平稳。
4. 这一次我用自身体重75公斤去压缩避震筒对比，实际上bilstein5100的压缩阻尼起码是LC150原车避震筒的压缩阻尼的2-3倍。

这么好,那回头我也要装一个,我一直都觉得普拉多的悬挂太硬了, 正在考虑换米其林公路胎, 看来这是个更好的解决方案

对了,这个对车后部重量轻后桥跳动过大有改善吗?

对后桥跳动也许有改善，但是效果远远没有bilstein对前桥的改善。
但是bilstein的压缩阻尼高于原车避震。照理说应该更硬。实际感受过弯也的确更硬了。
但是不知道为什么过搓板路以及减速带却更为安静了。下地库搓板路非常明显，因为两侧墙壁回音大，原车避震下车库基本不敢开窗户，而且过减速带会发出呲的漏气声。Bilstein完全不会。

还有LZ提到过"bilstein的氮气单管避震筒技术保证不会热衰减、基本终身耐用"
这个终身耐用是什么概念? 据说一般来说避震筒的寿命在10万KM左右, 这个能与汽车同寿命?

我买了普拉多以后经常看一个南非摄影记者兼越野专家Andrew St.Pierre White的介绍，他开越野车30-40年，奔驰G级、路虎卫士、路巡等等都开过，他讲过一个观点，就是所有OEM最不花钱的地方就是避震筒。在越野车上，这是不负责任的，他的一辆路虎卫士110型开了13万公里，基本非铺装路，前三万公里更换了2套原车的油压避震筒，从三万公里开始更换了bilstein避震筒，到13万公里卖车时，bilstein的状态比原车还要好。
这个南非人youtube上有许多视频，介绍关于越野内容，如能翻墙，可以找来看看。

Gas shock absorbers
Few vehicles have gas shock absorbers fitted as standard equipment and for vehicles expected to work long hours off-road they are essential. In the past, few four-wheel drive manufacturers have paid enough attention to shocks absorbers.
Working 4×4′s need gas shocks. For example, my own Land Rover 110 went through two sets of standard shock absorbers within 30 000 kilometers. Once the second set had worn out, the first being replaced under guarantee, I replaced them with Bilstein shocks. When selling the vehicle after clocking up 130 000 kilometers the shocks were as firm as when I fitted them. Gas shocks often make the ride a little firmer but the real advantage comes when cornering or carrying a load. The difference in my case was a significant improvement in ride even when compared with brand new, standard shock absorbers.
Why gas?
A shock absorber, simply described, is a metal tube filled with oil through which a piston moves. on the piston is a valve which permits oil to pass through a limited rate. The tube is connected to the chassis and through at a limited rate. The tube is connected to the chassis and the piston is connected to the axle. The oil’s limited travel damps the movement of the piston and therefore the axle to which it is attached. This prevents oscillation that the springs would create if left undamped. as the piston moves in the cylinder heat is generated. Heat thins the oil and makes the shock less effective. What is worse, the oil in a hard working shock mixes with the air and bubbles are formed. The mixture of hot air and hot oil is able to pass through the valve easier than pure oil, which means that the shock will lose its effectiveness, to the point where the ride becomes uncomfortable and unpredictable. Gas shocks are different in that they are pumped with a small quantity of inert gas. This gas cannot mix with the oil and so the main reason why shock-absorbers become soft as they get hot is eliminated. Shock-absorbers on a heavy loaded 4×4 on a rough sand track work almost as hard as shocks on a competition rally car. I know of one Range Rover which after being called to rescue the survivors of an accident in Northern Botswana (that was me in 1987), ‘cooked’ a gas shock by racing to get to the accident scene. the shock was blackened by heat and destroyed. I have used three brands of shocks in eight 4x4s that I have owned I can highly recommend Bilstein. They are undoubtedly very robust and are my first choice.
