Interesting question this, which I will try and answer to the best of my limited knowledge on the subject and by way of a ramble. If you have ever stripped an...
Excellent response! There is one thing, though, and that is the valve opening rate in cycles/sec. Since we're probably talking 4 stroke engine, should there...
Good questions In terms of the work done calculation, it doesnt matter if it does the work over 1/16th of the cycle or 1/4 or even one whole cycle, as it is...

... spend ... The idea is to have a close ratio main box so that an adequate number of gears are located where they are most needed. It only needs a three...
... How is this done? This is not like a regular car's manual transmission, where each gear ratio requires 2 gears. It's more like that of a bicycle, if I'm...
When you talk about tractors and trucks needing that much gear ratio in order for the engine to stay at its "optimum power band". Some say this "optimum power...

The splitter may also be in the form of a multispeed axle, remote from the main box. That is what I've seen, operated by pneumatics. It has a "toggel" on the...
There are people who seems to be concerned with the rotating mass of the transmission sapping energy and power. Especially in the racing world. Is this another...

Can someone explain what "powershift" transmission is? How does that work and what is the benefit? Is it just a hydraulicly activated clutch system? Thanks...
... hydraulicly ... Typically and at its simplest it is a gearbox where synchro units are replaced by modulated wet clutch packs so that as one releases ...
So does this mean there is less power loss in the shifting? Shifting time is also decreased? By the way, can you tell me about how much is the difference in ...

Actually, the concern is with rotational inertia, not so much with mass. Inertia is related both to mass and to diameter. There is a torque loss associated...

Instead of a "CVT", are there any "infinite ratio gearboxs"? By this I mean a gearbox that is capable of infinite ratio, but cannot be shifted continuously, ie...
Hey Guyz, Does anyone have a seminar report or a technical paper on CVT which covers all of CVT from introduction to details of CVT .I really need something...
I propose that infinite ratio has no meaning if not used in the context of a continuously variable transmission. From one end it looks like a freewheeling...
Jim, look up the Hydristor which is my invention. I can do this! Also, look up the word Hydristor on the Google search engine Tom Kasmer 607-7275709 just a...
Tom, I agree that Hydristor is one of several continously variable transmissions that goes to zero ratio and is thus an IVT. I think the term "infinite ratio"...
On some of the push belt CVTs they utilize a torque sensor to match the hydraulic clamping force to the transmitting torque to avoid unnecessary high clamping...
