Mechanics

Pedals

To fix the electric motors of both pedals, we have welded and screwed (because double made is always better :-) ) a framework of square pipes.

The usual idea was, to fix the electric motors on a wooden plate. But after we have made some inquiries, we have reached the conclusion that this wooden plate would not sustain the load of the electric motors. That's the reason for our decision to use the square pipes. These square pipes have also a much more bigger moment of inertia. And if you are honest to yourself: It looks really really cool :-)

To fix the motors in their right position, we have used a fixture which is made of aluminium rails (you can also call it "force fit" - for our needs the cheepest and ideal solution). These force fits are fixed with screws on the framework.

The electric motors have a maximum lifting force of 1100N (app. 110kg). More than enough for the work they have to do. A potentiometer is used to gather and to control the instantaneous position of the electric jack.

Steering wheel

The motor for the steering wheel (60rpm, torque: 8Nm) is also fixed by a force fit made of aluminium rails and screwed on the framework.

Transmission of force is realized by a chain and two chain wheels. Each chain wheel is fixed on the shaft of the electric motor and of the steering wheel.

To get the information in which position the wheel is, we have also fixed a potentiometer on the shaft of the electric motor.
