Sandwich gear train arrangement for multi-motor hybrid speed continuous power transmission

Recently, the interest of people in hybrid electric vehicles is increased. However, recent development is mainly related to the consumer passenger car market. The same technology is not applied to the commercial vehicle market. An electric motor used in a current consumer vehicle cannot be easily refitted into a commercial vehicle. In most cases, refitting of a motor into a power assembly requires comprehensive redesign of power assembly parts. In addition, an electric vehicle also has a problem of power loss during gear shifting. The problem is most common in heavy-duty commercial vehicles due to the fact that the vehicle slows down due to power loss and is easily perceived by a driver. Therefore, the field needs to be improved. 最近，人们对混合动力电动车的兴趣有所增加。然而，最近的开发主要与消费型乘用车市场有关。同样的技术尚未在商用车市场上得到应用。目前消费型车辆中使用的电动机通常不能轻易改装到商用车中。在大多数情况下，将电动机改装到动力总成中需要对动力总成部件进行全面的重新设计。此外，电动车辆在换挡期间还存在动力损失的问题。由于动力损失会导致车辆减速，这很容易被驾驶员察觉到，因此该问题在重型商用车中最为普遍。因此，该领域需要改进。
