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 effect is that we are actually coping with a varied quantity of tranny types including manual, typical automatic, automated manual, dual clutch, constantly adjustable, split power and genuine EV.
Until extremely recently, automotive vehicle producers largely had two types of tranny to choose from: planetary automated with torque converter or conventional manual. Today, nevertheless, the volume of options avaiable demonstrates the changes seen across the industry.
This is also illustrated by the many various types of vehicles now being produced for the marketplace. And not only conventional vehicles, but also all electrical and hybrid automobiles, with each type requiring different driveline architectures.
The traditional development process involved designing a transmission in isolation from the engine and the rest of the powertrain and vehicle. However, that is changing, with the restrictions and complications of the method becoming more widely recognized, and the constant drive among producers 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 advanced control systems. This is to assure that the best amount of efficiency and efficiency is delivered all the time. Manufacturers are under increased pressure to create powertrains that are brand new, different from and much better than the last version-a proposition that’s made more technical by the need to integrate brand components, differentiate within the market and do it all on a shorter timescale. Engineering teams are on deadline, and the development process must be better and fast-paced than previously.
Until now, the utilization 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 proven component-level analysis tools. While these are highly advanced tools that allow users to extract very reliable and accurate data, they are still presenting data that is collected without concern of the complete system.
