E400有個值得欣賞嘅地方是尾軸升高,其上玻璃只在下方髹上黑油遮蔽,但E50D嘅黑油部分則以外邊舖玻璃,再升高車內旁板,用多重料。講真塊玻璃爆就成塊塊換,E50D嘅設計最多只是撞到黑油區玻璃而未成塊爆入車廂。
置於E400MMC有冇新安排又唔係好覺

歐2吉拿應該會有多咗電子嘢?觀乎以往香港嘅巴士公司大規模轉用另一款車頭都唔係真係為提升排放表現。lg1200歐1變歐2個耗油程度唔會有大變化掛,不過似乎轉用吉拿仲拖副冷氣冇咁好飛。 |

近年減重係成為潮流,ADL 減得少,某程度上係因為早幾年 ADL E400 系列個種殼的確係同級車種中最輕,而佢用康偈歐六
人地引擎由 9 減到 5 公升,佢就用副比以前更大更複雜既 6.7 公升偈
就算新設計既殼輕左,引擎同埋新既減排裝置同埋因而增加既車身長度其實已經有成 200kg 咁上下
Exactly. ADL played that card when the E400 was launched, which is why the benefit is not as significant these days. However, I looked at the weight of a 9.9m London Trident/ALX400 and found that the E400 is only about 40kg lighter, which surprised me a little bit.

近年 B9 重量不斷追貼 ADL,但訂單一路流失緊,根本係反映當下年代巴士公司最睇重係油耗、重量定零件貯存,睇下一款車型優勝既地方咁岩巴士公司睇唔睇重咁解
同 E400 MMC 減重減得"特別少" 既原因差唔多既重有 Volvo B5LH 歐六,最近搭到英國頭一批服役既單門 B5LH,好力到出奇,
原來部車本身唔超過 11.6 噸
歐五變歐六,由 D5F210 4.8 公升變 D5K240 5.1 公升兼且多左一堆減排裝置,B5LH 似乎真係減到既又唔係太多,但歐六仍然比歐五版輕,都輕左大約 4-5 個人既重量
One key point is that ADL now has a very broad customer base and they have been very proactively trying to keep that market share. Also, off all the manufacturers, they are the only one that has a product lineup that straddles all sector of the UK bus market. I think these are the reasons why they have won the big groups' business this year.
On the B5LH btw, the weight-saving is actually not that much of a surprise, because Wright already said the Gemini 3 is 700 kg lighter, so the actual numbers is now stacking up with their claim. More than that, its transition to Euro 6 does not seem to impact its chassis design, unlike the E400 (both the E40D and E40H), and hence it can bag all that weight saving from the body.

問題係巴士既設計愈黎愈現代化,好多設備都會增加車重
ATENU 所謂減左差唔多大半噸都好 (相信係用最重既 ATE 比),其實同 ATR 比都差唔多重,ATENU 只係比 ATR 輕 100-200 kg 左右
(其實未必差咁多添,最低個數字好大可能係用低載 ATENU1 計出黎)
調返轉,好多人話 AP APM AVW AVBW 重,其實都係 16 噸咁上下數字,ATE/AVBE 所謂輕,只係比個 d 所謂重既 Wright / Neoplan 殼重 100-200 kg 左右,大約 3-4 個乘客重量
講到尾,ATE 車廂內只要比起隔離架 AVW 多幾個客,兩部車根本已經一樣咁重,顯然 ATE 撞起車黎係傷得誇張過 AVW (雖然真實比較到既例子就唔多)
結構安全同車重似乎無乜大關系,結構安全係同設計有關
Your point about weight creep is actually very important, and not a lot of people (esp. here) actually realise how bad it got in the last decade. For a like for like size, a Trident and B7TL is anything between 600-800kg heavier than a Volvo Olympian. On top of this, the larger variety of those types also became the favoured choice by operators to compensate the loss of seats in low-floor designs, so we went from the Olympian where the 9.6m version is the norm in the 90s, to the low-floor buses that are 10.5m or, in some cases, more. All that pushes the weight up.
However, are the AP, AVW etc really weigh only 16 tons? I find this very hard to believe because a single door tri-axle Olympian weighs some 17.2 tons, and like I said before, I expect low floor designs to be heavier. If anything, I though they would be closer to 18 tons, if not over that.

- 前幾日架 1300x 去左某個巴士大集會,摷到張相,11245 kg,似乎真係你估個數字重近 d
- 記得歐六 E400 (9544) 係比 B5TL (V6) 剛剛好重左 1 噸,最衰搭過幾次 9544 都無認真望下載客量
(印象中係望過,但唔記得,只知比 B5TL 少 10 個或以上)
Like I said, that 13xxx basically stacks up to Wrightbus' claim of 700kg saving in the Gemini 3.
On Euro 6 E400, I will find some time to track down 9544 actually, since of all the visits I have done at London lately, I only saw it once, and very briefly.

E50D 設計上可以升級到歐六唔算咩野大不了既事,要上歐六相信大部分 B9TL 都改裝到變成 B8TL,爭在值唔值得
...
其實如果用呢方面推論,Volvo 早係 1997-1999 年已經設計出一款巴士底盤係略加改裝後已經符合到 15 年後既歐六標準
You say that, but I have a gut feeling that we will not see a B8TL in any shape at all. In its place, a tri-axle B5LH will be offered instead. The reason I say this are 1. it can share with the existing B5LH production, and the design has got pretty decent power output; 2. The type has been well proven, both from reliability and economy points of view; 3. Volvo have already done away the diesel-only option for the 7900 and offer the hybrid as the only version; and 4. Doing this will drive down the type's price, and with greater volume production, the production cost shall come down as well. The lower purchase price can well be a market shaking move, considering the hybrids are 50% more expensive than a diesel equivalent.
On your last point, we probably have come to a point where low floor chassis design (esp. transverse engine design) has matured so much that there is very little that can be changed. The current E400 is basically a 2-axle Trident, and the B5TL is very much the same design as the B7TL as you said. The only one that is different is, ironically for all the sentiment it received from outside, the LT. That is the only UK double decker design that remotely resembles the full low-floor designs from the leading European rivals. I personally think that the StreetDeck can well be a very clever little package.

肯定冇咁重
城巴雙門12米蘭/豪講緊14.4公噸左右,老九舊直重係重咗,但都只係15.7公噸,AVW係少數幾款淨重過16公噸嘅車
而家香港啲12米車根本除咗E50D,冇其他三軸車可以攞足24公噸限重,12米豪都只係得22940kg限重,躉、舊直都只係23100kg,B10TL都係23公噸左右,12米蘭更少,限重得22050kg/22250kg
如果一架三軸雙層車淨重都17至18噸,喺香港即使計每個人重57kg (比起英國計法輕唔少),驗車嗰陣已經冇可能畀佢裝一百個人
參考資料:德國柏林雙層Lion's City比起香港啲車大咗成個碼去到近14米長先至淨重17公噸

9544 係 11835 kg,岩岩好比 V6 重 1 噸,所以記得好清楚,爭在唔記得企位爭幾多
(不過總載客量好似剛好就係 8x-90 vs 100,個重量差別大部分都係反映返係企位上)
好記得分別係唔同地方見過既 Optare 車身高背 100-102 座位 B9TL 先係 15.4 噸左右,一定輕過 16 噸
但個數字比想象中大好多,既然九巴裝埋冷氣都係 15-16 噸鬆 d,無理由熱狗版可以相差咁少
不過如果計埋凳同埋長度差別 (之前以為係 12 米,原來係 12.3 米) 似乎又唔出奇
http://www.transportengineer.org.uk/transport-engineer-features/weight-watchers-on-tour/49794
記得 coach 凳大約係 30kg 一對,就算當九巴上一代 80 座直梯車張凳都有 20kg 一對,淨係全車座位重量已經相差左 3/4 噸
再保守少少當九巴以前堆凳有 25kg 一對,都重係差半噸
加加埋埋即刻合理左好多
調返轉,個別英國巴士淨重數字應該錯得好緊要,例如 Transbus E200,竟然三架車都寫著淨重 12000kg 
講到輕重、性能,其實都係反映返巴士公司每個年代既考慮因素
以往 SPD、B6BLE、E300 訂單輸到一棟都無,個個去晒買真正既大型單層,貪佢用途廣泛
而家巴士使用年期咁短 (好似只係 14 年左右),用返同一個原因,正正就係唔需要太襟用/耐用既車
B7RLE、Man 18.240、Scania K系個 d 少左好多人買,呢兩年俾 E300 上晒位
不過到 Wright Streetlite 出黎,貨比貨之下 (大同細既 Streetlite 設計相似度好似比 E200 vs E300 更高) 又成功搶到唔少訂單走
講開又講,岩岩有行家貼出另一部 11.5 米 E400 MMC,似乎舊年已經砌好

Then I really wonder where did former Citybus 341 got all its weight from...

Having said that, I think your numbers are right. I just checked through my photos and dug up some numbers:
ADL E500 (First Glasgow): 15,200kg
Volvo B9TL/E500 3-axle (Dublin Bus): 14,524kg

講安全,另外又記得有人提過 Dominator 同鴨車車頭底盤有個 A 形結構,好似話係令重心偏向中間,剎車同埋穩定性較好,
而 Volvo B9 2型開始同埋同期既 Volvo 巴士底盤,底盤頭段都慢慢由 H 字形變到似似地 A 形,唔知係咪同一原因
鴨車車頭底盤車頭應該唔係 A 形結構,佢只係一條貨車陣,但唔係全直,類似勝利二型有高低位。 |
