传动变速箱

All of the transmissions available for sale today is continuing to grow exponentially within the last 15 years, all while increasing in complexity. The effect can be that we are now coping with a varied amount of transmitting types including manual, conventional automatic, automated manual, dual clutch, continually adjustable, split power and genuine EV.
Until extremely recently, automotive vehicle manufacturers largely had two types of transmitting to pick from: planetary automatic with torque converter or conventional manual. Today, however, the volume of choices available demonstrates the adjustments seen over the industry.

This is also illustrated by the many various kinds of vehicles now being produced for the market. And not just conventional automobiles, but also all electrical and hybrid vehicles, with each type needing different driveline architectures.

The traditional advancement process involved designing a transmission in isolation from the engine and the rest of the powertrain and vehicle. However, that is changing, with the limitations and complications of the method becoming more more popular, and the constant drive among producers 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 in addition rely on highly sophisticated control systems. This is to make certain that the very best degree of efficiency and functionality 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 complex by the need to integrate brand elements, differentiate within the marketplace and do it all on a shorter timescale. Engineering teams are on deadline, and the advancement process needs to be more efficient and fast-paced than ever before.
Until now, the usage of computer-aided engineering (CAE) has been the most typical 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 equipment. While these are highly advanced equipment that enable users to extract very reliable and accurate data, they are still presenting data that’s collected without concern of the whole system.
