All of the transmissions available in the market today is continuing to grow exponentially within the last 15 years, all while increasing in complexity. The result is definitely that we are now dealing with a varied number of transmitting types including manual, conventional automatic, automated manual, dual clutch, constantly variable, split power and genuine EV.
Until very recently, automotive vehicle producers largely had two types of transmission to choose from: planetary automated with torque converter or conventional manual. Today, however, the volume of choices available demonstrates the adjustments seen across the industry.
That is also illustrated by the many different types of vehicles now being produced for the market. And not only conventional Driveline gearboxes automobiles, but also all electrical and hybrid automobiles, with each type requiring different driveline architectures.
The traditional advancement process involved designing a transmission in isolation from the engine and all of those other powertrain and vehicle. However, that is changing, with the limitations and complications of this method becoming more more popular, and the continuous drive among producers and designers to provide optimal efficiency at decreased weight and cost.
New powertrains feature close integration of components like the prime mover, recovery systems and the gearbox, and also rely on highly advanced control systems. This is to guarantee that the best amount of efficiency and efficiency is delivered at all times. Manufacturers are under improved pressure to create powertrains that are completely new, different from and better than the last version-a proposition that’s made more technical by the need to integrate brand components, differentiate within the marketplace and do everything on a shorter timescale. Engineering teams are on deadline, and the development process must be more efficient and fast-paced than previously.
Until now, the usage of computer-aided engineering (CAE) has been the most typical way to build up drivelines. This process involves parts and subsystems designed in isolation by silos within the organization that lean toward tested component-level analysis equipment. While they are highly advanced equipment that allow users to extract extremely reliable and accurate data, they remain presenting data that is collected without account of the whole system.
While this may produce components that 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.
