Description

       

   <EMI ID=1.1> 

  
Het systeem heeft tot doel de fysische kracht voor het voortbewegen van een fiets te verminderen.

  
 <EMI ID=2.1> 

  
verhogen, uitgaande van dezelfde kracht op de trapper&#65533;

  
Omgekeerd kan eenzelfde moment verkregen worden met verminderde

  
 <EMI ID=3.1> 

  
beweeglijke vierzijden.

  
De trappers worden in het midden van de stangt aangebracht en beschrijven een cirkelvormige beweging zoals de trappers van de klassieke fiets. Dit is een belangrijk voordeel t.o.v. andere meer gesofistikeerde systemen waarbij de trappers een ingewikkelde baan beschrijven wat tegen de normale rijgewoonten indruist.

  
De vermeerdering van het moment wordt bewezen als volgt : 

  
 <EMI ID=4.1> 

  
moment M = l.P.cosCk bij .de klassieke fiets.

  
Het moment in het nieuwe systeem is eveneens maximaal voor

  
 <EMI ID=5.1> 

  
groter dan bij de klassieke fiets.

  
Besluit :

  
 <EMI ID=6.1> 

  
kleinere fysische kracht P uit te oefenen op de trappers dan bij de klassieke fiets. De konstruktie is eenvoudig en aan de rijgewoonten moet niets gewijzigd worden daar de trappers een cirkelvormige baan beschrijven zoals bij de klassieke fiets.



   <EMI ID = 1.1>

  
The aim of the system is to reduce the physical force for moving a bicycle.

  
 <EMI ID = 2.1>

  
increase, assuming the same force on the treadle &#65533;

  
Conversely, the same moment can be obtained with reduced

  
 <EMI ID = 3.1>

  
movable four sides.

  
The pedals are placed in the center of the bar and describe a circular movement like the pedals of the classic bicycle. This is an important advantage over other more sophisticated systems where the pedals describe a complex track that goes against normal driving habits.

  
The multiplication of the moment is proven as follows:

  
 <EMI ID = 4.1>

  
moment M = l.P.cosCk at .the classic bicycle.

  
The moment in the new system is also maximum for

  
 <EMI ID = 5.1>

  
larger than with the classic bicycle.

  
Decision:

  
 <EMI ID = 6.1>

  
less physical force P to exert on the pedals than with the classic bicycle. The construction is simple and the riding habits do not need to be changed as the pedals describe a circular track like the classic bicycle.
