比较不同的传动系统可知 ,在欧洲内燃机和带启动马达的多档圆柱齿轮变速器仍然占据领导地位。在最主要的轻型和中型轿车方面 ,机械自动变速器的份额将明显增加 ,因为它们具有减少燃油消耗和排放的潜力和突出的效费比。干式离合器作为一启动和换档元件 ,在传扭能力安装空间和操纵力等方面进一步发展后将能适应新的要求。而干式离合器特有的优点 ,如高效率和无阻力矩将继续保持下去 ,同时成本仍可维持在相对低的水平。在持续打滑时的热容量或热变形问题等缺点可通过增加能耗来解决。在一些不考虑舒适性的工况下 ,可通过合适的控制策略以避免离合器的过载 A comparison of different drivetrains shows that internal combustion engines and multi-speed spur gearboxes with starter motors still occupy a leading position in Europe. In the major light and medium sedans, the share of mechanical automatic transmissions will increase significantly as they have the potential to reduce fuel consumption and emissions and their outstanding efficiency / cost ratio. As a start-up and shift element, dry clutches will adapt to the new requirements as they further develop in terms of torque transfer capability and installation space. The advantages inherent in dry clutches, such as high efficiency and drag-free torque, will continue to be maintained while still maintaining relatively low costs. Disadvantages such as heat capacity or thermal deformation problems during continued slippage can be overcome by increasing energy consumption. In some cases do not consider the comfort conditions, through the appropriate control strategy to avoid overload of the clutch
