Bespoke gearbox design
Your gearbox, engineered only for you, quickly and affordably!
Why do you need a bespoke gearbox?
This is what our customers say when they come to us:
⇒ The off-the-shelf gearbox that our general supplier offers does not fit in the vehicle!
⇒ Our application is very specific so the gearbox requirements too. Nothing already available suits!
⇒ We already have the gearbox but the ratios we need are not available. Could you keep the gearbox housing and change only the internals?
⇒ We are using the same gearbox for years but the engine power has increased more and more and the reliability is not there anymore. Could you arrange that?
We can find a solution for all these customers, even when a very small set of parts is needed.
Is this affordable?
Bespoke design is usually expensive because
development costs are bigger than the price of gearbox itself.
Knowing that, Involute Transmissions has developed
a very special design method which reduces considerably the design time and so the cost.
This method is based on:
• Proprietary software developed by our engineers which allow for very quick design
• Business organization based on our F1 experience
How long it takes?
Depending on the project and the customer needs, it can take 2 weeks to 2 months. For instance, the below gearbox has been designed in 2 weeks:
What about manufacturing?
Some customers just need the drawings and design reports whereas others prefer us to deliver the complete gearbox. Our company is based in the factory of the company “Normandy Gears” therefore we can manufacture your parts in a very short period of time.
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).
