技术领域technical field
本发明属于电动车辆的动力装置领域，具体地说是一种电动车辆的同步驱动轮组，以带动该电动车辆直线移动，而不会因为动力输出不平均造成行走路线偏斜。The invention belongs to the field of power devices of electric vehicles, and in particular relates to a synchronous driving wheel set of the electric vehicle to drive the electric vehicle to move in a straight line without skewing the walking route due to uneven power output.
背景技术Background technique
按，一般如：电动自行车、电动车、电动轮椅、助行器及电动铲雪车等电动车辆，因为负载较低且不需要时速快，而不需使用石化燃料的引擎结构，大多是采用以电动马达作为旋转动力源，其利用电池的电力驱动电动马达运转而产生行走所需的动力，故不会造成空气污染。Generally, such as: electric bicycles, electric vehicles, electric wheelchairs, walkers and electric snowplows, etc., because the load is low and does not need to be fast, and the engine structure does not need to use fossil fuels, most of them use the following The electric motor is used as a rotating power source, which uses the electric power of the battery to drive the electric motor to run to generate the power required for walking, so it will not cause air pollution.
该等电动车辆也会因为不同的需求而使用不同的驱动轮组，例如：电动自行车或电动车等，由于有转向及动力加速等需求，大多将转向轮及动力轮分开设置，或有高转速设计的电动马达搭配其它变速机构而达到提高动力及操控性等功效。如：助行器或电动铲雪车等，则是因为必须搭配使用者的行走速度设计，虽然使用了高转速设计的电动马达，配合适当的动力传递机构，以将电动马达的高转速动力经过转换而成为高扭力动力，以带动该等电动车辆作移动，其设计是将单一旋转动力源经减速而输出至一输出轴上，并于该输出轴的两端部分设一轮体，使得两端的轮体作同步的旋转运动，再通过转向机制而进行，如：原地进行转弯移动或转向等动作；特别是电动铲雪车，因为在行进的过程中会不断地进行铲雪的动作，不仅阻碍极大且相当费力，而需要更充足的力量向前推动，在铲雪的过程中同步运转必须确实才不会发生偏斜，如发生偏斜时，操作人员就必须来回数次才能整理出供车辆或人员行走的通道，徒增人力及时间的浪费。These electric vehicles also use different driving wheel sets due to different needs, such as electric bicycles or electric vehicles, etc., due to the needs of steering and power acceleration, most of the steering wheels and power wheels are set separately, or have high speed The designed electric motor cooperates with other speed change mechanisms to improve power and controllability. Such as: walking aids or electric snowplows, etc., because it must be designed to match the walking speed of the user, although an electric motor with a high-speed design is used, and an appropriate power transmission mechanism is used to transfer the high-speed power of the electric motor through It is converted into high-torque power to drive these electric vehicles to move. Its design is to output a single rotating power source to an output shaft after deceleration, and set wheels at both ends of the output shaft so that the two The wheel body at the end makes a synchronous rotational movement, and then it is carried out through the steering mechanism, such as: turning or turning in place; especially the electric snowplow, because it will continue to plow snow during the process of moving. Not only is the obstacle huge and quite laborious, but it also needs more power to push forward. During the process of plowing snow, the synchronous operation must be sure so as not to deflect. If deflection occurs, the operator must go back and forth several times to sort it out. Existing passages for vehicles or personnel to walk will only increase the waste of manpower and time.

电力源为马达定子23供电，电力输入后，马达转子25与马达定子23之间产生电磁感应效应，使马达转子25相对马达定子23进行旋转，进而带动与马达转子25固接的转子套管24同步旋转；行星减速模组26中的太阳齿轮261随转子套管24同步旋转，通过三段式的减速后，由第三行星架2625带动输出轴22的两端同步旋转，进而带动两端的固定座27及轮体271同步旋转，使电动车辆1直线移动。The power source supplies power to the motor stator 23. After the power is input, an electromagnetic induction effect is generated between the motor rotor 25 and the motor stator 23, so that the motor rotor 25 rotates relative to the motor stator 23, and then drives the rotor sleeve 24 fixedly connected to the motor rotor 25. Synchronous rotation; the sun gear 261 in the planetary reduction module 26 rotates synchronously with the rotor sleeve 24. After three-stage deceleration, the third planetary carrier 2625 drives the two ends of the output shaft 22 to rotate synchronously, and then drives the fixed ends of the two ends.
