All of the transmissions available in the market today is continuing to grow exponentially in the last 15 years, all while increasing in complexity. The result is definitely that we are actually dealing with a varied quantity of transmitting types including manual, typical automatic, automatic manual, dual clutch, constantly variable, split power and genuine EV.
Until very recently, automotive vehicle producers largely had two types of transmitting to choose from: planetary automatic with torque converter or conventional manual. Today, nevertheless, the volume of choices available demonstrates the changes seen across the industry.
That is also illustrated by the countless various kinds of vehicles now being produced 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 the rest of the powertrain and vehicle. Nevertheless, this is changing, with the restrictions and complications of the method becoming more widely recognized, and the constant drive among producers 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 also rely on highly sophisticated control systems. This is to make certain that the best amount of efficiency and performance is delivered at all times. Manufacturers are under improved pressure to create powertrains that are brand new, different from and much better than the last version-a proposition that’s made more complex by the necessity to integrate brand elements, differentiate within the market and do it all on a shorter timescale. Engineering groups are on deadline, and the development process must be more efficient and fast-paced than previously.
Until now, the use of computer-aided engineering (CAE) has been the most typical way to develop drivelines. This process involves parts and subsystems designed in isolation by silos within the business that lean toward tested component-level analysis tools. While these are highly advanced tools that allow users to extract extremely reliable and accurate data, they remain presenting data that is collected without factor of the complete system.
