La lubrification en carter sec
Opter pour la lubrification en carter sec, c’est la garantie d’une lubrification efficace et d’un rendement hors norme !
La maîtrise de la lubrification en carter sec est une de nos compétences phares. Nous maîtrisons la totalité de ce système qui nécessite des pompes, des gicleurs, des réservoirs, etc.
Là encore, nous disposons de logiciels internes qui nous rendent complètement autonome sur la réalisation de ces systèmes complexes.
La denture asymétrique
Une évidence pour les transmissions qui travaillent principalement dans une direction.
Nous vous donnons accès à l’utilisation de dentures asymétriques. Cette technologie proposée depuis quelques décennies est restée l’apanage des transmissions très haut de gamme (aéronautique). Notre maîtrise de cette technologie nous permet maintenant de vous mettre à disposition ces dentures exceptionnelles pour des applications plus usuelles.
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).
