Driveline gearboxes

The variety of transmissions available in the market today has grown exponentially in the last 15 years, all while increasing in complexity. The result is usually that we are actually dealing with a varied quantity of transmitting types including manual, regular automatic, automatic manual, dual clutch, consistently variable, split power and natural EV.
Until extremely recently, automotive vehicle producers largely had two types of transmission to pick from: planetary automated with torque converter or conventional manual. Today, nevertheless, the volume of choices available demonstrates the adjustments seen over the industry.

That is also illustrated by the countless different types of vehicles now being manufactured for the market. And not merely conventional automobiles, 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. Nevertheless, this is changing, with the limitations and complications of this method becoming more more popular, and the continuous drive among manufacturers and designers to deliver 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 assure that the best amount of efficiency and Driveline gearboxes functionality 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 complex by the necessity 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 ever before.
Until now, the utilization 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 confirmed component-level analysis tools. While these are highly advanced equipment that allow users to extract extremely 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 with each other without prior account of the entire system can create designs that don’t work, resulting in issues in the driveline that are difficult and expensive to correct.
