Description

用于车辆的动力系统及车辆Power system for vehicle and vehicle 技术领域Technical field

新能源车辆通常采用电力或油电混合动力来进行驱动，其中电力驱动的来源主要为电机。为了简化布局和节约空间，一些新能源车辆将驱动电机直接套设在车桥的一侧半轴上，并对电机、变速装置和差速器进行集成式设计。由于电机的输出转速较快，在将电机的输出扭矩传递至车轮之前一般需要通过变速装置进行减速处理。New energy vehicles are usually driven by electric power or hybrid electric power. The source of electric drive is mainly electric motors. In order to simplify the layout and save space, some new energy vehicles will directly drive the drive motor on one side axle of the axle, and integrate design of the motor, transmission and differential. Because the output speed of the motor is fast, it is generally necessary to perform a deceleration process through a transmission device before transmitting the output torque of the motor to the wheels.
CN 107914704 A公开了一种用于新能源汽车驱动装置的一体式集成控制方法，其中实现该方法的驱动装置将电机同轴套设在差速器的长半轴上，并通过两组相互啮合的齿轮组将电机的输出扭矩减速后传递至差速器，其中，两组齿轮组中各有一个齿轮设置在与半轴平行的副轴上。在这样的驱动装置中只有两组齿轮对构成的变速装置，并且其传动比受到齿轮尺寸的限制，因此变速能力非常有限。CN107914704A discloses an integrated integrated control method for a driving device of a new energy vehicle, in which the driving device implementing the method sets a motor coaxially on a long semi-axle of a differential and meshes with each other through two groups The gear set of the motor reduces the output torque of the motor and transmits it to the differential, wherein one gear of each of the two sets of gear sets is arranged on a layshaft parallel to the semi-axis. In such a driving device, there are only two sets of gear pairs, and the transmission ratio is limited by the size of the gears, so the gear shifting capacity is very limited.
