Making a track drive trike (Part 1)



The crawlers are vehicles that have always attracted us as they are more uncommon compared to the usual ones that they use wheels. They are usually used by vehicles on the ground as they have a large contact surface with it and they have the potential to be tolerable in hardships. However, there are some drawbacks as their heavy weight, their high cost and some other.
Therefore, we decided to combine the wheels with the crawlers and connect them on our motorcar. So, we took the decision to make a vehicle, which at its back side would have a crawler and at the front would have two wheels.

Initially, we cut the gears, on which the metallic crawler spins. On its side we put a gear, from which the machine moves it. We shaped our framework by taking a tube of 50mm. The crawler was connected on the framework in such a way to Have the ability to be moved up and down when it meets obstacles on its way like stones and other things. To avoid swishing and to control this move responsibly, we had two springs connecting the framework and the Crawler.

The framework that we made is constituted by two pieces that are connected in the middle and they can be moved up and down. This move is limited with the help of an adjustable spring which allows a small move so the vehicle will be able to absorb all the swishes caused by the obstacles arisen. The front wheels were placed in their between width 90cm and they also have their own springs so they can be moved independently the one from the other. This gives the opportunity to the vehicle to have a good hold on an irregular ground and keep a good hold in steep hinges.

We placed our steering wheel that turns the two front wheels to the direction we want. Also, we used a machine from a scooter 50cc even if we knew that the machine was weak to move the heavy weight of our vehicle easily. Finally, we are very pleased from the first trials we had. That was the primary phase of the vehicle and we are very happy from the outcome of our construction. To sum up, our vehicle will be completed on the next video, when we are going to choose bigger wheels and motor and in general our construction will be finished.
