The invention relates to the field of vehicle assemblies, and discloses a pure electric internal and external double-ring planetary system power assembly which comprises a motor, an input shaft, an output shaft, an input gear, an output gear and an internal and external double-ring planetary mechanism. The motor is connected with the input gear through the input shaft, the internal and external double-ring planetary mechanism is connected with a caliper disc gear shifter through a first sun gear shaft and connected with a bidirectional wedge-shaped brake through a second gear ring, a combinedrotating arm in the internal and external double-ring planetary mechanism is fixedly connected with the output shaft, and the power assembly solves the problems that in an existing purely-electric automotive transmission system, fixed speed ratio transmission is implemented, low-speed climbing capacity is weak, electric system load impact is strong, motor limit speed is high, system running efficiency is low, an equivalent efficient running area is narrow, size is large, maintaining cost is high and the like.
Description
Technical field [0001] The invention relates to the field of vehicle assembly, in particular to a pure electric inner and outer double ring planetary system power assembly. Background technique [0002] With the continuous development of society and vehicle engineering technology, the number of cars is increasing, which has caused great pressure on the environment and energy. In order to solve the above problems, there is an urgent need for greater innovation in vehicle engineering drive technology. The existing vehicle engineering drive technology mainly includes two types, one is hybrid technology, and the other is pure electric technology. The above two technologies mainly involve the innovation of vehicle transmission systems. One is the introduction of energy storage devices, and the other is the introduction of electric drive devices, such as motors. In the current pure electric drive technology, most vehicles use motors and fixed-speed ratio gearboxes to drive vehicles, ...
