CVT-Continuously variable transmission


continuously variable transmission (CVT) is a transmission that can change steplessly through an infinite number of effective gear ratios between maximum and minimum values. This contrasts with other mechanical transmissions that offer a fixed number of gear ratios. The flexibility of a CVT allows the driving shaft to maintain a constant angular velocity over a range of output velocities. This can provide better fuel economy than other transmissions ....etc

hello,i dig your web site while searching for polaris gearing calculator about atv,it is for a scrambler 400 1999 full build with heavy mods,
i work and fine tune those thing for 20 years,here is my question:through the years i've tried many,many gearing combo,since the first stock set til now with new smaller tires.
i use the 2001 2x4 tranny for my scrammy,i want to put best power to the rear wheels using the stock clutchs (only parts differents are aftermarket like,weights,springs,helix..)the 01 tranny doesn't have the same gear ratio insid ....etc

Hey folks,
Here is a very raw/under developed seminar on the topic of operating systems.
This seminar is a based on a paper which i'll try to attach with this, You guys can absorb a very basic idea with these slides to research more. Although this project is very old and perhaps it has been dropped by the developers as well but the concept behind this is really beautiful.
Hope it will help. ....etc

Abstract:-
Our varying industrial needs demand more precise control of the outputs of our basic electrical prime movers i.e, THE MOTORS. Basically dc motors are easy to control compared to their ac counter parts, but they have their own limitations with increase in capacity. Conversely ac motors in particular squirrel cage induction motors are very economical but their spee ....etc

ABSTRACT
Continuously Variable Transmissions based on belts, pulleys, cones, discs, collectively friction transmissions, share many of the disadvantages of conventional hydraulic transmissions. CVTs require clutching mechanisms, hydraulic pumps to compress V belts between adjustable pulleys, and all have ablative belts, n ....etc

CONTINUOUSLY VARIABLE TRANSMISSION
A Seminar Report

ABSTRACT
Continuously Variable Transmissions (CVT) offer a continuum of gear ratios
between desired limits. This allows the engine to operate more time in the optimum range
given an appropriate control of the engine valve throttle opening (VTO) and transmission
ratio. ....etc

The stop go traffic condition has become synonymous with driving in our big cities. In such a case will automatics transmission make sense to the Indian customer. Well the Indians haven?t taken to automatics like fish to water. The reason being conventional automatics always consume slightly more fuel than manual transmission and the lack of sophisticated automatics.

With the increase in traffic conjunction in the cities stop go traffic has become a big hassle with constant gear changing. In such a situation CVTs or continuous variable t ....etc

CHAPTER1-INTRODUCTION
Unlike traditional automatic transmissions, continuously variable transmissions don't have a gearbox with a set number of gears. Continuous Variable Transmission (CVT), which is now replacing planetary automatic transmission in some of the automobiles. The most common type of CVT operates on an ingenious pulley system that allows an infinite variability be-tween highest and lowest gears with no discrete steps or shifts.
CVTs offer a continuum of infinitely variable gear ratios by changing the location of pulley ....etc
