Edyson CVT - continuously variable transmission
Variable ratio gearbox using only sprockets toothed gears pinions
This is not an epicicloidal transmission !
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.
Patent Protected Technology !
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.
The calculation of the efficiency of Edyson CVT has been done by the University of Padua and can reached the following LINK.
The patent also provides a simple addition, not published yet, to eliminate almost entirely the internal oscillations.
Edyson CVT 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 www.Ratiozero.com
Other possible applications are bicycles, motorcycles, cars, 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
