Hybrid power device and vehicle

Abstract

The invention discloses a hybrid power device and a vehicle. The hybrid power device comprises an engine, a first motor, a second motor, a first planet row, a second planet row, a first brake and a second brake, a first sun gear is connected with a second sun gear, and a first planet carrier is connected with a second gear ring; a first input shaft is connected with the first sun gear; the secondinput shaft is connected with a first gear ring; a first brake is arranged to lock or release the first gear ring, and a second brake is arranged to lock or release a second planet carrier; the engineis arranged to be selectively connected with or disconnected from the first input shaft and the second input shaft, the first motor is connected with the second planet carrier, the second motor is connected with the second sun gear, and the second gear ring is arranged to output power to the wheels. According to the hybrid power device, hybrid power shunting and output power shunting can be achieved, various pure electric and hybrid power driving modes can be achieved, and the fuel economy can be improved.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a hybrid power device and a vehicle with the hybrid power device. Background technique [0002] Due to the gradual deterioration of the environment, new energy vehicles, hybrid vehicles and other technologies are getting more and more attention. There are some defects in the hybrid vehicles of related technologies, which makes it difficult to popularize the hybrid vehicles. Most of the related technologies adopt a single planetary row structure, which can only realize single-mode hybrid power splitting; the engine torque can only be balanced by the first motor alone, and increasing the engine will cause the motor balance torque to be too large, which limits the scope of use of the system; When driving, the first motor reverses to provide power, and the second motor generates electricity, resulting in electric power circulation and low efficiency; the second motor is direct...

AI Technical Summary

Problems solved by technology

In Toyota's fourth-generation products, there is still a single-mode hybrid power shunt because the system is a single-planetary row; when driving at high speed, the first motor reverses to provide power, and the second motor generates power, resulting in electric power cycle, and the efficiency is relatively low. Low technical issues to overcome
