All of the transmissions available for sale today has grown exponentially in the last 15 years, all while increasing in complexity. The effect is certainly that we are now coping with a varied amount of tranny types including manual, typical automatic, automated manual, dual clutch, consistently variable, split power and natural EV.
Until very recently, automotive vehicle manufacturers largely had two types of transmission to pick from: planetary automatic with torque converter or conventional manual. Today, nevertheless, the volume of choices available demonstrates the adjustments seen over the industry.
That is also illustrated by the countless various types of vehicles now being manufactured for the market. And not simply conventional vehicles, but also all electrical and hybrid automobiles, with each type needing different driveline architectures.
The traditional development process involved designing a transmission in isolation from the engine and all of those other powertrain and vehicle. Nevertheless, this is changing, with the limitations and complications of the method becoming more widely recognized, and the continuous drive among manufacturers and designers to provide optimal efficiency at reduced weight and cost.
New powertrains feature close integration of elements like the primary 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 efficiency is delivered all the time. Manufacturers are under improved pressure to create powertrains that are brand new, different from and better than the last version-a proposition that’s made more complex by the need to integrate brand elements, differentiate within the marketplace and do it all on a shorter timescale. Engineering teams are on deadline, and the development process must be better and fast-paced than ever before.
Until now, the utilization of computer-aided engineering (CAE) has been the most common way to build up drivelines. This technique involves elements and subsystems designed in isolation by silos within the organization that lean toward verified component-level analysis tools. While they are highly advanced equipment that enable users to extract very dependable and accurate data, they remain presenting data that’s collected without factor of the whole system.
