The invention provides a speed control system and an automobile comprising the speed control system. The driving gear is designed to be meshed with different positions in the axial direction of the bevel gear under the action of centrifugal force at different rotating speeds, so that when an automobile is in a low-speed state, the torque output to wheels can be increased, and working conditions such as low-speed climbing can be well adapted; when the automobile is in a high-speed state, the torque output to the wheels can be small, and the high-speed driving working condition of the automobile can be well adapted. Moreover, due to the fact that the speed control system adopts the two-stage speed reduction mechanism, the automobile can adopt a small speed ratio, the speed of the whole automobile can be increased faster along with increase of the rotating speed of the driving motor, and therefore the acceleration performance and the maximum speed of the whole automobile can be obviously improved under the working conditions of medium and high automobile speeds. The variable speed system is suitable for different working conditions without increasing the power, the size and the like of the driving motor.

    本申请提供一种变速系统及包含所述变速系统的汽车。本申请通过设计主动齿轮在不同转速时,在离心力的作用下啮合于伞形齿轮轴向上不同位置,使得汽车处于低速状态时,输出至车轮的扭矩能够增加,能够很好的适应低速爬坡等工况;汽车处于高速状态时,输出至车轮的扭矩能够较小,能够很好的适应汽车高速行驶的工况。并且,由于本申请的变速系统采用二级减速机构,因而汽车可以采用较小的速比,整车车速随驱动电机转速的增加能够得到更快的提升,进而使得中、高车速工况时,整车加速性和最高车速得到明显提升。通过本申请的变速系统在不增加驱动电机的功率、体积等适应不同的工况。
