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 definitely that we are now dealing with a varied amount of transmitting types including manual, standard automatic, automatic manual, dual clutch, consistently variable, split power and 100 % pure EV.
Until very recently, automotive vehicle producers largely had two types of transmission to select from: planetary automatic with torque converter or conventional manual. Today, however, 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 manufactured for the marketplace. And not just conventional vehicles, but also all electric and hybrid vehicles, with each type requiring different driveline architectures.

The traditional advancement process involved designing a transmission in isolation from the engine and all of those other powertrain and vehicle. However, this is changing, with the restrictions and complications of the method becoming more more popular, and the continuous drive among producers and designers to deliver optimal efficiency at decreased weight and cost.

New powertrains feature close integration of components like the prime mover, recovery systems and the gearbox, and also rely on highly sophisticated control systems. This is to guarantee that the very best amount of efficiency and performance is delivered at all times. Driveline gearboxes Manufacturers are under increased pressure to create powertrains that are brand new, different from and better than the last version-a proposition that’s made more technical by the necessity to integrate brand elements, differentiate within the marketplace and do everything on a shorter timescale. Engineering groups are on deadline, and the development process needs to be more efficient and fast-paced than ever before.
Until now, the use of computer-aided engineering (CAE) has been the most typical way to build up drivelines. This technique 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 enable users to extract very reliable and accurate data, they remain presenting data that’s collected without concern of the complete system.

While this can produce components that work very well individually, putting them collectively without prior factor of the entire program can create designs that don’t work, resulting in issues in the driveline that are difficult and expensive to improve.
