Q:请问纯电动汽车还需要变速器吗?A:您好,从传统低速电动汽车、电动自行车,到工厂电动机等,甚至广义上电动机的驱动方式(比如电风扇、刮胡刀等)看,电动汽车的确可以不需要变速器,但考虑到市场对电动汽车性能的需求,电动汽车还是需要变速器的。举一个简单的数学例子,家用汽车通常的最大速度限定在240公里/小时,轮胎规格用R16。根据这两个参数,大致可以算出的结果是,如果车子极速达到240公里/小时,此时轮胎的转速达到每分钟三千转左右,也就是说,轮胎最大限定是在这个转速,如果再加速,那就会出现滑动而不是滚动,但是,许多乘用车的交流电动机额定转速就是每
A: Hello, from the traditional low-speed electric vehicles, electric bicycles, to the factory motor, and even the generalized motor drive mode (such as electric fans, razors, etc.) look, electric Cars do not really need a transmission, but given the market’s need for EV performance, EVs still need a transmission. For a simple example of math, the typical maximum speed for a home car is 240 km / h and the tire specification is R16. According to these two parameters, we can roughly calculate the result is that if the car speed reaches 240 km / h, then the speed of the tire reaches about 3000 RPM, that is, the maximum tire is at this speed, if the re-acceleration , Then there will be sliding rather than rolling, but many passenger cars AC motor rated speed is
