在auto-online請教sutl兄的懸吊形式,在我的學習裡,應該被稱為扭力樑,也就是目前所謂的非獨立式拖曳臂,其實都是扭力樑的變化,而拖曳臂的定義,小弟轉述如下: Trailing arm A suspension element consisting of a longitudinal member that pivots from the body at its forward end and has a wheel hub rigidly attached to its trailing end. A sufficiently rigid trailing arm can provide all of a wheel's location. In that case it is similar to a semi-trailing arm, except that its pivot axis is exactly perpendicular to the car's longitudinal center line. 依照這樣的定義,非獨立式拖曳臂(應當被稱為扭力樑)雖然在構造上類似,但是並非完全一樣。 Torsion beam suspension Most modern mini cars up to C-segment (for instance, VW Golf) employ torsion beam as the rear suspension. Why? compare with double wishbones, multi-link and trailing arm suspensions, it engages little width of the car, thus enable greater rear seat room. It is cheaper too. Compare with MacPherson strut, its shock absorber is shorter and can be inclined steeply away from the vertical, thus engage less boot space. In fact, torsion beam suspension is only half-independent - there is a torsion beam connecting both wheels together, which allows limited degree of freedom when forced. 至於sutl所指的網址,裡面的圖片,並不能讓我判斷他是扭力樑或是拖曳臂(事實上有些國外網頁,對於PSA車,本來說是扭力樑'torsion beam',後來說是拖曳臂),因為個人認為關鍵點可能在於跟車身的連結的部分... <br>
