New Gearbox Could Revolutionise Motoring
Controlled Rotation System Gearbox
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.
History Of Gearboxes
Gearboxes have evolved beyond recognition within living memory. As such, vehicles from the fifties tend to have three-speed manual boxes and some – such as the Bond Minicar Mark F – lack reverse. In contrast, models from the seventies often have four-speed units and their successors from the late eighties tend to have five. Today, a large proportion of new cars have six forward gears. Furthermore, automatics from (say) the eighties tend to have one less sprocket than their manually geared equivalents. This hinders performance and fuel economy. Some of today's automatics, however, have eight gears and match or exceed the performance/fuel efficiency of manuals. Furthermore, some enable the driver to cruise in full-auto mode or select cogs individually via a lever or paddles behind the steering wheel. In simple terms, such units come in two forms: a traditional box of cogs or a continuously variable unit that houses variable diameter pulleys shaped liked opposing cones. These are connected by a chain and ensure that any gear changes are extremely smooth and whisper quiet. But perhaps even this looks old fashioned compared to the new Controlled Rotation System Gearbox.
