Dry cavity gearbox
Dry cavity is the only way to get best-in-class efficiency and efficient lubrication!
Oil system design for dry cavity is one of our most advanced skills. We master the complete oil system (pump, nozzles, tanks, etc.) and we are autonomous on every component. Our proprietary software gives us high versatility in the design to suits your requirements.
Asymmetric gear teeth
This should be the standard for transmissions that always work in the same direction!
You can have access to the use of asymmetric gears. This technology has been developed during the last twenty years but only for very top-end transmissions. We are bringing this technology to every other application that always work in the same direction. The benefits in terms of efficiency, reliability and mass are huge. Thanks to our dedicated software, we can offer this technology while keeping manufacturing costs almost similar to standard gears. This takes into account gear design but also manufacturing tool design.
Bespoke gearbox design and manufacturing is the leitmotif of our company. Our processes are adapted to this business. Therefore we can offer best-in-class race motorbike gearboxes perfectly suited to your needs. You can fully take advantage of your engine power curve while increasing the reliability.
The BE gearboxes designed by PSA-Peugeot-Citroën are strong gearboxes that are still very much used in race cars (especially on 2L engines). These gearboxes are fitted with synchronizers based on the “New-Process” system. Synchronisation is achieved by means of a threaded conical aluminium ring sliding against a steel flange attached to the pinion. Although satisfactory in everyday use, the aluminium rings become weak points when used in severe application, like in motorsport (rally, track, hillclimbing). This is mainly due to the fact that the cast aluminium used for the original parts loses its mechanical properties when the temperature rises sharply. This results in a much shorter life span of the ring as well as difficulties in synchronization, which is detrimental to performance and reliability. For this reason, Involute Transmissions designs and manufactures synchronizer rings in high performance wrought aluminium, which allows a very high endurance of the rings in competition. This aluminium is usually used in severe aeronautical applications. Unlike the original rings, they are screwed onto the bars, which makes replacement easy and affordable. These rings are suitable for all BE gearboxes (BE1, BE3 and BE4).
