[馬里的科學實驗室]手煞車詳解!
【手煞車】
手煞車(Hand Brake),它與正常的煞車系統有一定的區別,它不像普通煞車那樣,對四個輪進行煞車,手煞車只是單獨對後輪進行煞車,而它的主要作用在於停車時起到長期煞車的效果,較為常見的,較老一點的手煞車多數與使用拉線形式設計,而煞車方面則採用傳統的鼓式煞車器。通過駐車煞車拉桿(手煞車手把)拉動拉線頂開後輪的煞車器的摩擦片與煞車鼓接觸,從而起到煞車效果。但現在很多車輛都會採用四輪碟盤煞車,所以有些車廠會在後輪煞車碟盤之中設計出為手煞車專用煞車鼓,於是就有了“Drum in Disc Brake”(碟鼓一體設計),其實除了這樣的做法之外,有些碟盤製動的車型由於位置不足,所以其手煞車就直接利用拉線拉動卡鉗。
【演變】
而隨著電子化的普及,現在新車的手煞車也已經電子化,它利用電信號代替傳統拉線驅動手煞車系統,在眾多的中高級車中都開始普及這種電子駐車系統了。除了這些常在原裝車型上看到的駐車製動外,還有一款液壓駐車(液壓手煞車),在甩尾車、表演特技用前驅車和拉力賽上常常見到,裝有液壓手煞的車型只要輕輕一拉煞車拉桿便能抱死後輪。

brake drum 在 怪獸 導 Facebook 的最佳解答
This is our first attempt for freestyle class at AMD World Championship of Custom Bike Building and we took home 4th!!
The whole bike was designed with vintage lines and all modern process into it, the look was going for a vintage rigid/springer bike but made it with modern CNC billet/tubing bolted together for that modern "lug" frame look, softail with underseat rear shock and billet rear leg/tubing front leg springer front end with air shocks
quick release half tanks, left side for electric inspection(battery and fuse), right side for fuel
front and rear Beringer inboard brake with rear modified with a sprocket makes a vintage drum brake look.
Dual front S&S heads with dual Keihin FCR carbs, Rough Crafts custom made billet lifter blocks, custom made intake and exhaust for the "dual front head" setup, plus Rough Crafts polished Split/Fin rocker cover for Twin Cam and hand made push rod tubes/collar

おめでとう、
HONDA and DREAM CB750FOUR (Doremushebe ..floatage.. Foix) are motorcycles to which Honda Motor Co., Ltd. was doing the manufacturing sales.
Details until developing
At first, the reputation in foreign countries was not fragrant though HONDA that accomplished complete conquest by the road racing world championship at that time aimed to advance worldwide on a commercial side, and announced and had exported the new car of dream CB450 etc. one after another except the desire. It is because there was respect that lacks from a room that the rider can manipulate even if the performance is put out by a small displacement little to easiness to get on because this values a top speed of the motorcycle as a flow from the race.
Then, all technologies at that time will be concentrated on manufacturing as a motorcycle at that time because it becomes a maximum level displacement though the vehicle that can correspond also to a recent race standard after coexisting of the performance and room is attempted because of the expansion of the displacement is planned and production was decided.
The vehicle manufactured thus is dream CB750FOUR (henceforth CB). The dream of the car name is a series trademark that HONDA was using for the efficient at that time, sports type.
The main equipment and performance of CB
Engine Parallel four cycle four cylinders OHC
The cylinder is narrowed a little by using a lot of parts of aluminum and width and the weight of the engine are suppressed though the engine adopted four parallel cylinder engine of two-wheel mass production first car considering externals. About the Shaiki valve, not DOHC but easiness to get on and productivity for the high rotation used from the low rotation were considered to a racer at that time, and ..daring.. SOHC was adopted. As two-wheel mass production car, it is the first time to have equipped four cylinders all with the carburetor.
Engine performance- 738cc・67 horsepower and maximum speed 200 km/h
The displacement and the horsepower of the engine were decided in shape to compare engines of this industry and others car. The performance that it is possible that it put on the speed at 200 km/h was still secured though it was suppressed from the priority of easiness to get on to the output extent more than the highest all motorcycles on the market, at that time, value though it was also possible that this engine raised the performance a little more. However, this is called the purpose is for the parts supplier to clarify the responsibility to the manufacturing thing to HONDA though parts only for CB will be both made as for a tire at that time and the chain because it is not possible to finish corresponding to this horsepower, and the explosion and the plasmotomy were repeated while developing.
Front wheel disk brake
The manufacturer named the MV Agusta had already used a small amount of front wheel disk brake in the production vehicle. However, it has been decided to make it equip with the disk brake by "Authoritative word" of Soichiro Honda who is finally the president and exhibit though the comparison discussion was done which the drum or the disk to be used just before Motor Show to which a real car of CB is exhibited because it was unexampled in two-wheel mass production car. As a result, it is told that it had a hard time in the accumulation of knowhow though the disk brake will be adopted for the first time as two-wheel mass production car. It is true that working of the brake worsens extremely when the rain running.
