Steering & Hub supports

Just like the hub supports, the main goal with the design of the steering supports is to reduce their weight. During the design of GP17, we created lightweight but also rigid supports, capable of handling circuits with more deteriorated surfaces. Since then we have used a similar design (with only slight changes) for the following prototypes.

In GP17 and GP19, these supports were very close to the vehicle’s structure, so it was necessary to thin out the bulkheads in certain areas that suffered interference from the steering system.

On the other hand, GP21 will no longer have this problem: as the structure is tighter at the front,

we were able to compensate and move the monocoque wheels apart, maintaining a minimum distance of 500 mm between each of the front wheels, thus ensuring the ideal behaviour of the supports.

Its ease of assembly is also a great advantage, since it is no longer necessary to assemble the hubs under pressure, as was the case with GP19’s conical hubs and shafts.

For the same prototype, it was decided to implement off-the-shelf hubs, not only to reduce the production time of the vehicle, but also to increase the availability of parts in case of need of replacement.
