Een klein jaar geleden hebben we hier een keer opgezocht hoe dat ook alweer zat met die kabels. Ik weet dat ze in '99 zijn ingevoerd.
Maar of ze er nog zijn of wat ze wel en niet aan moeten kunnen (kwa krachten) is me alweer ontschoten.
Het is wel terug te vinden iig.
Wheel tethers
Since 1998, F1 cars have had to fit wheel tethers connecting the wheels to the chassis. This rule was introduced to try to stop wheels coming free and bouncing around dangerously during an accident. Unfortunately, wheels still do come off the cars during crashes, tragically killing a marshall at the Italian GP in 2000. The FIA have introduced an extra tether to each wheel for the 2001 season to try to stop the wheels coming off and causing injury to other drivers, marshals or spectators. The tether must attach to the chassis at one end, with the other end connecting to the wheel hub.
The wheel tethers are made by one of three companies in the UK, Future Fibres in London being one of them, and take the form of a rope. The tethers used in F1 are a derivative of high performance marine ropes, made especially for each car. They are made from a special polymer called polybenzoaoxide (PBO) which is often called Zylon. This Zylon material has a very high strength and stiffness characteristic (around 280GPa) much like carbon, but the advantage of Zylon is that it can be used as a pure fibre unlike carbon which has to be in composite form to gain its strength. The drawback of Zylon is that is must be protected from light, so it is covered in a shrink wrapped protective cover. The tethers are designed to withstand about 5000 kg of load, but often they can break quite easily during an accident, especially if the cable gets twisted by the broken suspension members. The teams normally replace the tethers every two or three races to ensure that they can withstand the loads put on them during an accident.
