All of the transmissions available in the market today has grown exponentially in the last 15 years, all while increasing in complexity. The effect is that we are now dealing with a varied quantity of tranny types including manual, typical automatic, automated manual, dual clutch, consistently adjustable, split power and genuine EV.
Until extremely recently, automotive vehicle manufacturers largely had two types of tranny to pick from: planetary automated with torque converter or conventional manual. Today, nevertheless, the volume of choices available demonstrates the changes seen over the industry.
This is also illustrated by the countless different types of vehicles now being produced for the market. And not only conventional automobiles, but also all electrical and hybrid automobiles, with each type needing different driveline architectures.
The traditional development Driveline gearboxes process involved designing a transmission in isolation from the engine and all of those other powertrain and vehicle. Nevertheless, that is changing, with the restrictions and complications of the method becoming more more popular, and the continuous drive among manufacturers and designers to deliver optimal efficiency at reduced weight and cost.
New powertrains feature close integration of components like the prime mover, recovery systems and the gearbox, and in addition rely on highly sophisticated control systems. That is to make sure that the best degree of efficiency and performance is delivered all the time. Manufacturers are under increased pressure to create powertrains that are completely new, different from and much better than the last version-a proposition that’s made more complex by the need to integrate brand components, differentiate within the market and do it all on a shorter timescale. Engineering groups are on deadline, and the advancement process needs to be more efficient and fast-paced than ever before.
Until now, the use of computer-aided engineering (CAE) has been the most common way to build up drivelines. This process involves parts and subsystems designed in isolation by silos within the business that lean toward confirmed component-level analysis tools. While these are highly advanced equipment that enable users to extract very reliable and accurate data, they remain presenting data that’s collected without factor of the whole system.
While this may produce components that all work nicely individually, putting them together without prior concern of the entire system can create designs that don’t work, leading to issues in the driveline that are difficult and expensive to improve.
