Edyson CVT - continuously variable transmission

Variable ratio gearbox using only toothed gears sprockets pinions

(this is not an epicicloidal transmission !)

Patent pending, owner Pavilcu Edyson.

Edyson CVT is a stepless speed variator using only toothed gears /sprockets, which can be used on any traditional engine (gasoline, diesel, CNG), electric motors, steam or wind turbines, bicycles (human power), as well as a large number of industrial or agriculutre applications, replacing the current transmission also toothed belt or chain drive, however, every time and need some adjustment of the ratio in a mechanical transmission.

Description:
The invention consists in the variation of the radius of the trajectory of toothed pinions participating in gear, obtaining in this way the continuously variable transmission, with a mechanical efficiency over 95%, and the torque equal to any mechanical actual solution.

The CVT device can work completely in an oil bath, so there are no mechanical parts that have slippage, overheating or wear and withstands at high speed and power applied.

Thanks to the fact that, and exclusively composed of gears can transmit the usual power than conventional automatic gearboxes or traditional current with the advantage of having small dimensions, less components, lower weight, and also a lower cost.

This CVT gearbox system can replace the V-belt systems, transmissions with varying diameter in a continuous manner, and many others based on friction force then acting as the primary means for transferring the movement, with limited overall power and energy losses inevitable. The current exchange rate can withstand much higher power with minimal power consumption.

Other possible applications are bicycles, motorcycles, cars, automobils, boats, gearboxes, electric motors, steam and wind turbine, as well as a large number of industrial or agriculture applications whenever is necessary some adjustment of the gear ratio.

The current prototype demonstrate the high reliability and easy to manufacture. To increase the variation range of this systems can be connected in cascade.

Innovative aspects:
- The possibility to chose any ratio value without any interruption or jumps in the rotation.
- This gearbox variator CVT has the weight and complexity comparable to existing systems.
- Changes the transmission ratio in a continuous manner during operation, even when stationary.
- This gearbox variator system CVT, lightweight, compact and cheap (fully mechanical).
- Can be used as a real traction control without "cutting" the engine.
- Improved efficiency in the traditional combustion engines considerably improving the posivive ecological impact on large scale.

Market opportunity for the Infinitely Variable Transmission system:
- This CVT design is a step change on existing CVT technology
manufacturing simplicity on existing production lines
- As oil diminishes and prices rise, the world is pushing for improved efficiency
- Can work like a traction control in automotive
- The CVT can reduce costs in an electric cars by replacing the “controller” that varies the speed

Benefits:
- Increased efficiency - less fuel consumption, less emissions -ecological
- Simple design - produced on existing production lines
- Fewer parts - less cost
- Powerful - a greater range of heavier duty applications

The prototype of the CVT variator Edyson designed for an electrical motorcycle with the above mentioned sizes can transfer:

- Power: around 60 HP
- Torque: 150Nm
- RPM max: 15,000
- Variation range from 1:1 to 2:1
- Weight around 10 kg

The CVT system can be designed for any vehicle and adapt for any power transmission by changing some dimmensions.

If you still think about this CVT to be an epicicloidal transmission, then you should read all one more time, becouse this is not an epicicloidal transmision !
