Abstract

The invention discloses a three-gear parallel shaft type double-motor three-planet-row hybrid power system. The system comprises an engine, a flexible connector, a shell, a center shaft, a first hollow shaft, a second hollow shaft, an output front shaft, an output rear shaft, a first planet row, a second planet row and a third planet row. The center shaft, the first hollow shaft, the second hollowshaft, the output front shaft, the first planet row, the second planet row, the third planet row, the first motor and the second motor are all arranged in the shell, the first hollow shaft is sleevedwith the center shaft, and the first hollow shaft is sleeved with the second hollow shaft. The system aims to solve the problems that a motor in an existing hybrid power assembly system is low in maximum rotating speed, large in peak torque and high in motor cost; and the axial length is large, the requirement for the arrangement space is high, and the vehicle model adaptability is poor are solved.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a three-speed parallel-shaft dual-motor three-planet hybrid power system. Background technique [0002] The driving performance of a vehicle depends not only on the engine, but also on the transmission and the matching rationality of the transmission and the engine. Automobile transmission can adapt to the different requirements of driving wheel traction and vehicle speed under the conditions of starting, accelerating and overcoming various obstacles. With the development of science and technology, continuously variable transmission is an ideal transmission system for vehicles. It has the ability to continuously change the transmission ratio. Theory It can make the engine run in the ideal working range all the time, so as to improve the power and economy of the vehicle. [0003] A simple planetary gear mechanism is the basis of a speed change mechanism. Usually, the speed ...
