Edyson IVT - Infinitely Variable Transmission
Infinitely variable ratio gearbox with neutral using only sprockets toothed gears pinions
This is not an epicicloidal transmission !
Edyson IVT 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.
Patent Protected Technology !
Edyson IVT bicycle hub (3D printed ) new prototype
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 IVT 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 IVT 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.
Edyson IVT bring a lot of benefits into an electric
motors transmission (and also on other transmission systems) because
can maintain the electric motor at a relatively constant speed
(selected at an optimum efficiency/torque point for the motor) and
adjust the vehicle's forward speed by varying the transmission ratio
over a smooth continuous range with electronic choice of ratio.
With an efficency about 97% you loose only 3% of energy instead of much
more in heat with AC motor and controller.
A
real and running application is Andeguro
Bike with IVT Edyson hub,
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.
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
