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 many various kinds of vehicles now being manufactured for the market. And not just conventional automobiles, but also all electric and hybrid automobiles, with each type needing different driveline architectures.
The traditional advancement 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 this method becoming more more popular, and the constant drive among manufacturers and designers to deliver optimal efficiency at decreased weight and cost.
New powertrains feature close integration of elements like the prime mover, recovery systems and the gearbox, and also rely on highly sophisticated control systems. This is to assure that the best degree of efficiency and overall performance is delivered at all times. Manufacturers are under improved 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 necessity to integrate brand components, 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 usage 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 proven component-level analysis tools. While they are highly advanced tools that allow users to extract extremely dependable and accurate data, they remain presenting data that is collected without concern of the whole system.
