Good topic (CVT gearbox)

無段波箱在RC應用的可能性.

Kyosho 1/9 Terrano used this CCVT gearbox, but it is discontinued.

almost 20 yra ago

CCVT is problematic...

cvt is an ancient invent, it is dying.

I don't think so, the technology is old but nowadays materials reliability is different. Engine power increase alot but Centax clutch, 2 speed gear ratio are limited the power, unless we can close ratio 3 speed transmission coming out. Seems, Schumacer has launched a 1/10 with 3 speed .28 engine few yrs ago, but not popular.

回復 beebone 的帖子

you ar the best, yr opinoin always make sense,
令我想到一個案例~
上世紀中GM最先發明(轉子引擎),結果是放棄了研究同量產,只有今天日本仔的RX7/RX8借助牠來賣gimmick 和改進, they are based on advance sci. also

硏究下硏究下

The structure of the Schumacher is same as that use in BMT 1/8 on-road many years ago. The structure is similar to the 2 speed transmisshion now we are using but it use a click ( fly-weight ) to lock with the pin in the housing of 2nd speed and 3rd speed instead of centrifugual shoes. When the 3rd speed engaged, the click of the 2nd speed will rub with the housing ( rotate in reverse direction as the 1st gear ) of the 2nd speed gear which will cause power lost.

For sure the bell housing cause heat  and power lost, wat I mean more gear and closer ratio driven more linear power and fuel consumption

no need to get too complicated, RC is just play, why make it too complicated??

of course it's not a toy, the correct term is "money pit"

Or money burner
