This is my last idea, a simple recuperation energy system, adaptable for almost all longboards, let me show it to you.
The idea is simple, when you are surfing with your longboard and you want brake, or maybe if are running down a slope and you want brake, or whenever you want reduce the longboard speed, you can use this system Easy-KERS for keep the energy, and recover it when you need it.
What is KERS?
KERS means Kinetic Energy Recovery System, it’s a mechanism for reduce the speed of a vehicle and storing a part of this kinetic energy.
Some KERS transform this kinetic energy in electeical energy, and others KERS keeps the kinetic energy in a flywheels.
In our case, we use a flywheels for store this energy.
How works Easy-KERS?
Easy-Kers has two parts, one of them, is the Pedal set, and the other one, is the flywheel part. These two parts are joined by a elastic belt.
Part 1 – Braking
When you are riding fast, and you want stop, you push the pedal, Then, Two cilinders of rubber get in contact with the Long board wheels. Now the elastic belt is in tension and it’s transmiting energy to the flywheel, which is begining to whirl fast.
In this moment you are transfering energy from longboard wheels to flywheel .
Part 2 – Energy stored
When you have stopped to brake, you lift the pedal. Thanks to the elasticity of the belt, the pedal return to original position (no contact). Now the flywheel is whirling very fast, storing the kinetic energy, although the longboard may be stopped.
Part 3 – Recover the energy.
Now is time to recover the energy. In this moment the longboard wheels aren’t whirling or are whirling slow, and you want to take boost.
Then you push the pedal, the belt begin to be taut and the rubber cylinders get in contact with the longboard wheels, which is whirling slower than rubber cylinders
In this part you are transferring energy from flywheel to longboard wheels.
The simplicity of this KERS system make itself:
-Easy to install
-Universal for almost all longboards
– The possibility of recovery energy,
– The Easy-KERS add to longboard a brake that it didn’t have before.
-You need modificate your long permanently
-Increase the weight of long board
-When the flywheel is turning could add annoying vibrations to longboard
Entire assembly weighs no more than 1,4 Kg
All the kit is fabricated in aluminium, except the flywheel.
The flywheel weight is 0.9Kg, it’s have the most part of weight, it is necessary for store the more possible kinetic energy .
How modificate the longboard:
In the next pictures we can see how to modify the longboard.
I have done 4 configurations in Solidworks, for demonstrate the different types of longboard and the final result when it is modify.
that’s all folks¡
If you have any doubt, please don’t doubt in ask¡
