摘要

乘用车变速器类型的发展清楚地表明，电动动力系统的汽车数量显著增加。由于动力系统的电气化，电池电动汽车(BEV)所需的齿轮总数大大减少。变速器变得更轻，更紧凑，其复杂性降低。这些变化留下了一个悬而未决的问题，即未来是否还需要传输。然而，在功率密度、效率和NVH方面的要求越来越高。为了满足这些要求，大量的研究项目正在进行中，这些项目都面临着电气化传动的挑战。下面的文章对这些研究项目进行了概述，并展示了未来电气化动力系统中变速器的必要性。

On the future of gears in electrified drive trains

The development of transmission types for passenger cars clearly shows a significant increase in vehicles with an electrified powertrain. Due to the electrification of the powertrain the total number of necessary gears is drastically reduced in battery electrical vehicles (BEV). Transmissions become lighter, more compact and their complexity is decreased. These changes leave the question open whether transmissions are still needed in the future. However, the requirements in terms of power density, efficiency and NVH are becoming more demanding. To meet these requirements, a large number of research projects are in progress which face the challenges in electrified transmissions. The following paper gives a broad overview over those research projects and shows the essential necessity of transmissions in electrified powertrains in the future.

期刊介绍： IJPT addresses novel scientific/technological results contributing to advancing powertrain technology, from components/subsystems to system integration/controls. Focus is primarily but not exclusively on ground vehicle applications. IJPT''s perspective is largely inspired by the fact that many innovations in powertrain advancement are only possible due to synergies between mechanical design, mechanisms, mechatronics, controls, networking system integration, etc. The science behind these is characterised by physical phenomena across the range of physics (multiphysics) and scale of motion (multiscale) governing the behaviour of components/subsystems.
