Multi-core pure electric module power plant

Abstract

The invention provides a multi-core pure electric module power plant, and belongs to the field of vehicle power speed transmissions. The multi-core pure electric module power plant with motor being adopted and outside rotor as an example comprises at least two motor devices, at least two sun wheels, at least two sets of planetary wheels, at least one inner gear ring, at least two planetary frames, a support plate, output gears, a fixing shaft, variable gears, a parking brake device and a differential mechanism. The output ends of the motor devices are connected with the power input ends of the sun wheels. The sun wheels are mounted on a power shell. Each sun wheel is connected with one set of planetary wheels in a meshing mode. Each set of planetary wheels are connected with one inner gear ring in a meshing mode. The inner gear rings are mounted on a sun wheel shaft and an intermediate support plate. The output gears are fixed to the planetary frames. The output gears are connected with the variable gears in a meshing mode. According to a multi-core module power, the high efficiency working area of the motor is used to realize different revolving speed and torque output through a mechanical gearbox. The switching between torque and revolving speed is selected reasonably, and the energy is used to a maximum extent so that the existing energy has a longer mileage.

Description

technical field [0001] The invention relates to the field of vehicle speed-changing power devices, in particular to the core technology of multi-motor speed-changing power for pure electric vehicles, which belongs to the multi-speed module power device. Background technique [0002] It is the general trend to simplify the structure and reduce the cost of electric vehicles. In the new energy era, we need to conduct more in-depth research on the power of electric vehicles. Economy, safety, energy saving, intelligence, modularization, and lightweight will be the main directions of future development. [0003] The existing gasoline-electric hybrid electric vehicles have internal combustion engines, generators, and electric motors at the same time. They are used to drive the vehicle alternately or jointly. Energy recovery devices are used in hybrid vehicles, and different power transmission systems are used to achieve energy-saving effects. , Oil and electricity multiple sets of ...
