Yes, I know it's 2014 but it was intended to be published on 2013. This is the begining of a series. Each year I will make a new version of this car with more features or just with a different skin. This one is packed with 2 PF-L for propulsion, and 1 PF-M for steering.
Technical datasheet
- Propulsion: 2 PF-L
- Max speed: 5,6 km/h
- Steering: 1 PF-MType - Rack and pinion (Return to center)
This hasn't been an easy creation, due to the complications that have appeared when I included return to centre steering, and 2 PF-L for propulsion, both working together. The bodyframe is built around the battery box, solving the emplacement problem. It can be divided into 2 parts: one includes the battery box and the front with the steering mechanism, and the rear one, which is partially suspended and houses the 2 PF-L for propulsion.
The return to center steering is based on the Shepoo's idea, and I have only adapted to the bodyframe and to the rack and pinion mechanism. It also has a gear ratio of 1:1.67 because using a 8 tooth gear over the rack didn't allowed me to do close turns. To see detailed information about steering mechanisms click here.
Propulsion is made with 2 PF-L hard coupled, so we double the power but having the same speed. The final gear ratio is 1:1.67, although the gear ratio is low, the speed is quite good but reduced when turning because of multiple motors working at the same time.
Finally, want to say that this model has been quite satisfactory, because there has been a long time since I didn't make a proper one, passing through one or two prototipes and ideas. The next model? Thinking about a SUV.
