All of the transmissions available for sale today is continuing to grow exponentially in the last 15 years, all while increasing in complexity. The result is usually that we are actually coping with a varied quantity of transmitting types including manual, conventional automatic, automated manual, dual clutch, continuously adjustable, split power and genuine EV.
Until extremely recently, automotive vehicle producers largely had two types of tranny to select from: planetary automatic with torque converter or conventional manual. Today, nevertheless, the volume of options avaiable demonstrates the changes seen across the industry.
That is also illustrated by the countless various kinds of vehicles now being manufactured for the market. And not just 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 all of those other powertrain and vehicle. However, this is changing, with the restrictions and complications of the method becoming more widely recognized, and the constant drive among producers and designers to provide optimal efficiency at reduced weight and cost.
New powertrains feature close integration of components like the primary mover, recovery systems and the gearbox, and also rely on highly sophisticated control systems. That is to guarantee that the best amount of efficiency and performance is ಡ್ರೈವ್ಲೈನ್ ಗೇರ್ಬಾಕ್ಸ್ಗಳು 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 complex by the need to integrate brand components, differentiate within the market and do everything on a shorter timescale. Engineering groups are on deadline, and the advancement process must be more efficient and fast-paced than previously.
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 equipment. While these are highly advanced equipment that allow users to extract very reliable and accurate data, they remain presenting data that is collected without concern of the whole system.
While this may produce components that work very well individually, putting them jointly without prior thought of the entire system can create designs that don’t work, leading to issues in the driveline that are difficult and expensive to correct.
