The variety of transmissions available in the market today is continuing to grow exponentially within the last 15 years, all while increasing in complexity. The effect is usually that we are now coping with a varied amount of tranny types including manual, typical automatic, automatic manual, dual clutch, continuously adjustable, split power and genuine EV.
Until extremely recently, automotive vehicle producers largely had two types of tranny to pick from: planetary automatic with torque converter or conventional manual. Today, however, the volume of choices available demonstrates the changes seen across the industry.
This is also illustrated by the countless different types of vehicles now being produced for the market. And not only conventional vehicles, but also all electric 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, that is changing, with the limitations and complications of this method becoming more widely recognized, and the continuous drive among manufacturers 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. That is to assure that the best degree of efficiency and efficiency is delivered at all times. Manufacturers are under increased 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 elements, differentiate within the marketplace and do everything on a shorter timescale. Engineering groups 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 develop drivelines. This process involves parts and subsystems designed in isolation by silos within the organization that lean toward verified component-level analysis tools. While these are highly advanced tools that enable users to extract very dependable and accurate data, they are still presenting data that’s collected without consideration of the whole system.
Driveline gearboxes is made use of to suit any kind of day-to-day program.
