10. the wheelchair 
 
10.1. chassis 

 

The chassis is the base of the wheelchair. It contains wheels, drive motors, 
batteries, electronics and seat lift. The steel parts of the chassis are 
electrolytic anodized and powder coated to ensure a long life without 
corrosion.   
 
 
 
 
 
 
 
 
 
 
 
Each of the front wheels is propelled by a powerful drive motor. These motors 
also take care for the steering of the wheelchair. With this system it is possible 
to turn on the spot. This makes the wheelchair optimal for indoor use. 

10.1.1 chassis suspension 

 

The chassis has independent suspension on each of the four wheels. The 
stiffness can be adjusted to your personal requirements.   
 

 

 

 

 

 

 

front suspension 

 

                   rear suspension
