Driveline gearboxes

The variety of transmissions available in the market today is continuing to grow exponentially in the last 15 years, all while increasing in complexity. The effect can be that we are now dealing with a varied quantity of transmission types including manual, regular automatic, automated manual, dual clutch, continually adjustable, split power and genuine EV.
Until extremely recently, automotive vehicle manufacturers largely had two types of transmission to select from: planetary automatic with torque converter or conventional manual. Today, nevertheless, the volume of choices available demonstrates the changes seen over the industry.

This is also Driveline gearboxes illustrated by the countless various kinds of vehicles now being produced for the marketplace. And not simply 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 this method becoming more widely recognized, and the continuous drive among manufacturers and designers to provide optimal efficiency at decreased weight and cost.

New powertrains feature close integration of elements like the primary mover, recovery systems and the gearbox, and in addition rely on highly sophisticated control systems. This is to make sure that the best degree of efficiency and overall 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 technical by the necessity to integrate brand elements, differentiate within the market and do it all on a shorter timescale. Engineering teams are on deadline, and the advancement process must be better and fast-paced than ever before.
Until now, the use of computer-aided engineering (CAE) has been the most common way to build up drivelines. This process involves components 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 allow users to extract very dependable and accurate data, they remain presenting data that is collected without factor of the whole system.

While this can produce components that work very well individually, putting them jointly 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 correct.
