Hot Bodies designers had an important decision to make before getting started on the off-road platform: what kind of drivetrain would be best? While the belt-drive Cyclone touring car is certainly the best on-road 4WD racer there is, the designers weren't sure a belt drivetrain could properly deal with the rigors of off-road racing.
Finally the decision was made for the shaft drive design for two main reasons:
1. The more direct response of a shaft drive system gives competitive Off Road racers the extra control they need. In Off-Road racing, throttle response on rough terrain or in the air is much more important for controlling the car than in an on-road environment.
2. Using a shaft drive train, meant our designers could ensure a sealed drivetrain that would be protected against the elements and be more reliable over bumps and through the ruts and therefore deliver a higher efficiency.
One word about torque steer: This is an issue in on-road cars with their narrower track, smaller tyres and shorter suspensions. In Off-Road cars, however, the mass of the tyres is much higher and the suspension is much wider. Therefore the force created by the rotating shafts is insignificant in relation. Bottom line torque steer is not an issue at all and the advantages of the shaft drive make it the superior system for Off-Road.
The foundation of the Cyclone D4 is its sturdy double-deck chassis. Made from woven graphite because of its low weight and high strength, the lower chassis is 2.5mm thick and the front and rear upper chassis pieces are each 2.5mm thick. Connecting the upper and lower chassis are the front and rear moulded composite gearboxes and the aluminium motor mount/middle bulkhead.
To make sure the chassis is extra-stiff and allows the suspension to do the work it's designed to do, the upper decks are held in place with a total of 11 flat head countersunk screws. The screws are arranged in a fully symmetrical pattern to minimise the effects of tweak on the suspension. |
