Anti-roll bars are like 'sideways springs', they only work laterally.Here's how they work:
防傾桿如同側向的彈簧，它們只在橫向運動時有作用。這裡是說明它如何作動的：
if one side of the suspension is compressed,one end of the bar is lifted. The other end will also go up, pulling the other side of the suspension up also, basically giving more resistance to chassis roll.
當單邊的的懸吊被壓縮時，防傾桿的一端被抬起。另一端也跟著上昇，同時也舉起另一端的懸吊一起上昇，其本上給底盤側傾更多的阻力。
How far and how strongly the other side will be pulled up depends on the stiffness and the thickness of the bar used:a thin bar will flex a lot, so it won't pull the other side up very far, letting the chassis roll deeply into its suspension travel.
防傾桿的強度及厚度，決定了懸吊另一端上昇的距離及程度：一隻直徑小的防傾桿會產生很大的彎曲，所以無法使懸吊另一端上昇很多，使的側傾很大深入到它的懸吊行程。
Note that the bar only works when one side of the suspension is extended further than the other, like when the car is cornering. When both sides are equally far compressed, like when the car is braking, the bar has no effect. So anti-roll bars only affect the lateral balance of the car, not the longitudinal balance. Unfortunately, anti-roll bars aren't the only things affecting the car's roll stiffness; they work in conjunction with the springs and dampers.
請注意防傾桿只有在懸吊的一端伸長量大於另一端時作動，例如車輛轉彎時後。當防傾桿的兩端的懸吊壓縮量相等時，例如車輛煞車，此時防傾桿並不會有效果。所以防傾桿對車輛只有橫向的平衡效果，沒有縱向的平衡效果。很遺憾的防傾桿不是決定車輛側傾量的唯一裝置;它同時有關係到彈簧和減震桶。
Suppose you add an anti-roll bar at the rear of your car without changing any of the other settings. When the car enters a turn, the chassis starts to roll. Normally, the suspension on the outside of the turn would compress, and the one on the inside would extend, making for a lot more pressure on the outside tire.
假設你在車輛的後方增加防傾桿而沒改變其他的設定。當車輛進入彎道時候，底盤開始側傾。一般來說，位於彎道外側的懸吊會被壓縮，而彎道內側懸吊會伸長，使的彎道外側的輪胎壓力變大。
With the anti-roll bar however, the suspension on the inside will be compressed, so the chassis will roll less, and the rear of the car will sit lower than normal. So the rear has more weight on it, and it's distributed more evenly over the two tires. This makes for a little more, and more consistent traction.
安裝後防傾桿後，彎道內側的懸吊被壓縮，所以底盤側傾變少，使的車尾高度較之前低。所以分配於後方的車重增加，且重量更平均的分配在後方的兩個輪胎。這使的後方抓地力增加並且更加一致。
Remember that this is in the beginning of the turn, the situation is different in the middle of the turn.
請記住，這只是入彎時，在彎道中段（出彎時）的狀況是不同的。<下段開始說出彎的狀態>
Normally, without the anti-roll bar, the chassis would stop rolling when the roll torque is fully absorbed by the outsid e spring. But with the anti-roll bar, some of that torque is absorbed by the anti-roll bar, and used to compress the inside suspension. So the outside suspension won't be compressed as much as it normally would, making the rear of the chassis sit up higher than normal, so less weight is on the rear of the car, and more at on the front. It's as if suddenly the rear has become stiffer, making for more steering and a little less rear traction.
一般來說沒有防傾桿時，底盤會在側向Ｇ值完全被外側彈簧吸收時停止側傾。但有防傾桿時，某部份的側向Ｇ值被防傾桿吸收，並且轉移去壓縮內側的懸吊。所以出彎時外側懸吊的壓縮量，會比沒防傾桿時來的少，使的出彎時，車尾高度比沒後防傾桿時後來要來的高些，使的車尾配重變小車頭配重增加。這就好像突然車尾懸吊變硬，使的轉向性增加，且使的出彎時後輪的抓地力變小。
Rear traction is more consistent however, because the weight is distributed more evenly over the rear tires, unless the track is really bumpy, that is; anti-roll bars can really mess up a car's rough track handling, so they're rarely used on bumpy tracks.
不管如何，後輪的抓地力將更穩定一致，因為重量更平均的分配在兩個後胎上，但是如果路面十分的不平整，防傾桿會使的操控性變差，所以防傾桿極少使用在路面崎嶇的賽道。
＜下半段要說前防傾＞
Adding an anti-roll bar at the front of the car has a similar, but opposite effect: it decreases steering, but makes it much smoother and more consistent.
在車輛前方安裝防桿桿的效果是類似的，但效果相反：前防傾桿減少轉向性，但是前防傾讓過彎更平順且更一致。
It can stop the front from 'biting into' the surface too much, making the turning radius big and smooth. This can come in handy on large, wide tracks.
它可避免車頭陷入地面太多（前輪軟腳），讓轉向半徑變大且更平順。它是益於操作於大且寬的跑道。
Math-wise, the torsion stiffness of the middle part of the bar goes up with the fourth power of the bar's diameter, and for the two side parts, torsion stiffness goes up with the square of the diameter. Keep this in mind while changing anti-roll bars.
套用數學公式，防傾桿中段的扭矩硬度，約１／４扭力和防傾桿直徑成正比，至於兩端支臂的部分，扭矩和防傾桿直徑平方成正比。換防傾桿時把這段放在心中即可。＜這段我也不太會翻譯
