The Controlled Rotation System Gearbox could revolutionise motoring - and cycling – and shipping - and windmills - and numerous other types of machine. Why? Because this new transmission – which has been developed by Parts Services Holland – has several advantages over its traditional counterparts. It is, for example, lighter, has very few components, requires no maintenance and operates without lubrication (oil). Let us consider how it works. The Controlled Rotation System Gearbox incorporates two circular discs that are connected by a strong, high-friction, belt. As such, it lacks the traditional sprockets found in most of today's systems. Remarkably, the diameter of these discs can be increased and decreased via a digitally controlled hydraulic oil pump and slide units. This process effectively creates different gears that enables the vehicle to proceed at a wide rage of speeds. The concept was created for bicycles after its inventors – who live in the Eindhoven region of The Netherlands - saw professional cyclist Andy Schleck lose his chain at a crucial point of the 2010 Tour de France. This prototype then evolved into a system for cars which measures thirty centimetres, by twenty-two, by eighteen. The engineering company expects its revolutionary gearbox to 'change the automotive industry on a worldwide scale'. That could happen if it is reliable.
