After searching the existing technologies, it is found that the two-speed transmission for electric vehicles adopts both the parallel shaft arrangement and the planetary row arrangement. . For a two-speed transmission with a parallel shaft arrangement, the shifting of gears is usually achieved through a synchronizer or clutch; for a two-speed transmission with a planetary row arrangement, the shifting of gears is mostly achieved through a combination of clutches or brakes .

二挡降一挡过程，通过换挡控制单元实现离合器420(常开)由工作状态切换到不工作状态，即第二行星排行星架310与中间轴140由结合切换到分离状态，制动器410由不工作状态切换到工作状态，即第二行星排内齿圈340由与壳体100分离可动切换到与壳体100连接固定不动。In the process of downshifting from the second gear to the first gear, the clutch 420 (normally open) is switched from the working state to the non-working state through the shift control unit, that is, the second planetary carrier 310 and the intermediate shaft 140 are switched from the combination to the separation state, and the brake 410 is switched by The non-working state is switched to the working state, that is, the second planetary ring gear 340 is movably switched from being separated from the housing 100 to being connected to the housing 100 and being fixed.
倒挡时，驱动电机反转(与正转方向相反)，离合器420(常开)不工作，即保持常开状态，中间轴140与第二行星排行星架310分离，制动器410工作，起到制动作用，第二行星排内齿圈340固定不动，驱动电机的动力通过驱动电机轴110末端传递到第一行星排太阳轮220，第一行星排太阳轮220通过第一行星排行星轮I230和第一行星排行星轮II240将动力传递到第一行星排内齿圈250，第一行星排内齿圈250再将动力传递到中间轴140，中间轴140带动与其连接的第二行星排太阳轮320，第二行星排太阳轮320将动力传递到与其啮合的第二行星排行星轮330，第二行星排行星轮330既自转又公转，第二行星排行星轮330带动第二行星排行星架310转动，第二行星排行星架310再将动力传递到与其相连的输出轴150，实现动力的输出，使整车倒向行驶。When in reverse gear, the driving motor reverses (opposite to the forward direction), the clutch 420 (normally open) does not work, that is, it maintains the normally open state, the intermediate shaft 140 is separated from the second planetary carrier 310, and the brake 410 works to play Braking effect, the second planetary row inner ring gear 340 is fixed, the power of the drive motor is transmitted to the first planetary row sun gear 220 through the end of the drive motor shaft 110, and the first planetary row sun gear 220 passes through the first planetary row planetary gear I230 and the first planetary row planetary gear II240 transmit the power to the first planetary row ring gear 250, and the first planetary row ring gear 250 then transmits the power to the intermediate shaft 140, and the intermediate shaft 140 drives the second planetary row The sun gear 320, the second planetary row sun gear 320 transmits power to the second planetary row planetary gear 330 meshed with it, the second planetary row planetary gear 330 both rotates and revolves, and the second planetary row planetary gear 330 drives the second planetary row planetary gear The planetary frame 310 rotates, and the second planetary planetary frame 310 transmits power to the output shaft 150 connected to it, so as to realize the output of power and make the whole vehicle run backwards.
空挡时，离合器420(常开)和制动器410均保持不工作状态，使得驱动电机轴110与输出轴150处于分离状态，切断了动力的传递。When in neutral, both the clutch 420 (normally open) and the brake 410 remain in a non-working state, so that the drive motor shaft 110 and the output shaft 150 are in a separated state, cutting off the transmission of power.
当整车以一挡行驶需制动时，驱动电机由电动机模式切换到发电机模式，对传动系统起到制动作用，将整车的行驶动能转换为电能。When the vehicle needs to be braked while driving in first gear, the drive motor switches from the motor mode to the generator mode, which acts as a brake on the transmission system and converts the driving kinetic energy of the vehicle into electrical energy.
当整车以二挡行驶需制动时，驱动电机由电动机模式切换到发电机模式，离合器420(常开)不工作，制动器410工作，对传动系统起到拖动作用，提高制动能量的回收效率。When the whole vehicle needs to be braked when running in the second gear, the drive motor is switched from the motor mode to the generator mode, the clutch 420 (normally open) does not work, and the brake 410 works, which plays a drag role on the transmission system and improves the braking energy. recycling efficiency.
该电驱动系统的换挡执行元件按照表1进行工作。The shift actuators of the electric drive system work according to Table 1.
表1中“○”表示分离，“●”表示结合,B表示制动器410，Cl表示离合器420(常开)。In Table 1, "○" means separation, "●" means combination, B means brake 410, Cl means clutch 420 (normally open).
