Continuously Variable Transmission System

Sri Venkateswara College of Engineering, Anna University, Chennai, India

India is primarily an agricultural country, and modern technology plays a major role in its agricultural practices. Its farming machines are powered by internal combustion engines, with speed and torque variations effected using conventional gears, which causes the engines to lose fuel efficiency over time. To increase engine efficiency and to achieve infinitely variable transmission, this team is developing a Pulley Type Continuously Variable Transmission that can be incorporated into existing tractors and harvesters, eliminating the need for gears and gear boxes in the power train. A simple arrangement of two variable diameter pulleys connected by one angular contact Vari-speed Elastomer belt can be attached to the drive shaft, the pulleys being actuated by stepper motors and/or clutch-based hydraulic control systems. This changeover could result in major savings in fuel by running the engine at its efficient speed and driving at any desired speed through stepless variations.

very cool, what kind of gear range does it have?

[abhisheksms]

@bbglas007 This is a prototype having infinite gear ratio between 0.7 to 1.5. Using a different belt and increasing the size of the pulley, any gear ratio can be achieved. The output can also be coupled to another similar CVT to achieve much greater ratio.

Hi.Where is possible to buy this cvt and where to find more info?

[stoichiometric]

Hydraulic CVT would be much more practical in a tractor.

your music make me horny

[steveBB30]

Nice and simple but isn't it the same same thing as DAF's Variomatic? Believe the patents are now held by Bosch)

Music is distractive, it doesn't aid anything in this video.

The rest is good.
