Abstract

The invention discloses a same rotating arm dry type four-speed pure electric power system. A motor of the same rotating arm dry type four-speed pure electric power system is connected with an input star mechanism and a middle star mechanism. The input star mechanism, the middle star mechanism and a double-planetary star mechanism are all connected with a rotating arm. The input star mechanism is connected with a II gear shifting plate. The double-planetary star mechanism is connected with a III gear shifting plate and a IV gear shifting plate. The middle star mechanism is connected with a one-way clutch and a I gear shifting plate. The outer ring of the one-way clutch is connected with a box body. The rotating arm is connected with an output transitional gear set. The output transitional gear set is connected with a differential mechanism. The I gear shifting plate is connected with a I gear shifting mechanism in a matched mode. The II gear shifting plate is connected with a II gear shifting mechanism in a matched mode. The III gear shifting plate is connected with a III gear shifting mechanism in a matched mode. The IV gear shifting plate is connected with a IV gear shifting mechanism in a matched mode. According to the same rotating arm dry type four-speed pure electric power system, the low-speed climbing capacity is high, the electric system load impact is small, the limit rotation speed of the motor is low, the operation efficiency is high, the size is small, the maintenance cost is low, multi-gear transmission is achieved, and the transmission performance and the whole machine quality are effectively improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a dry-type four-speed pure electric power system with a rotating arm suitable for pure electric vehicles. Background technique [0002] With the continuous improvement of the maximum speed of electric vehicles, the continuous improvement of climbing performance, acceleration performance and cruising range requirements, and the development trend of continuous cost reduction, high-efficiency multi-speed automatic power transmission system has become a key link to solve the above problems. In the early days of electric vehicles, designers planned to use multi-speed transmissions to assist motors to drive vehicles in order to reduce motor torque, controller current, improve system performance, improve vehicle power performance, extend cruising range, protect battery packs, and reduce system load. weight. However, due to international fuel prices and supply issues, the developmen...
