其實點解NWFB 33XX咁短要用中軸做驅動軸,令到好容易法尾?BB龍都用尾軸做驅動軸啦,用中軸做驅動軸唔係只不過係想減少轉彎半徑咩?

用中軸做驅動軸會唔會係為左增加部車既驅動力？

(如果講發尾，AP 好似發得仲勁 )

The Dennis Trident 3 10.3m was a product after the development of the 12m version, if I remember correctly. The driven-axle are almost always equipped with one extra tyre on both sides in order to increase grip of that axle. As grip increases at the mid axle, the pivot point moves forward, which then decreases the turning radius. You are correct that the design benefits turning and tailing shifting becomes more prominent.

As to why this design was also applied on the 10.3m version, the most probable explanation would be to shorten the wheelbase of the chassis and avoid redesigning the last two axles, as this was the easiest way (and also the cheapest).

Anyone, please let me know if I am wrong.

其實33XX同10XX/11XX/12XX/14XX/16XX/30XX/3601都係Trident, 點解唔可以統一驅動組合呢? 點解一定要33XX用尾軸做驅動軸呢?

因為3軸Trident系列全部係縱置引擎佈局，Dominator/Dragon/Condor都係橫置引擎佈局。
如果縱置引擎仲要尾軸驅動，部車嘅尾跨就會好似2800咁長
至於點解Trident用縱置引擎佈局呢？我相信係因為如果以M11引擎+波箱長度，再用橫置引擎佈局(好似M11龍/鷹咁)，引擎室就會冇位擺水箱，要搞到超豪咁
用縱置引擎佈局嘅話，有半部引擎嘅長度去咗下層尾排凳底，波箱就喺地板下面，於是車尾右邊就有好充裕嘅空間擺水箱。

所以對操控性嘅影響都係其次，最主要係車尾空間嘅應用導致中軸驅動佈置嘅出現。
