Hybrid Power Plants and Vehicles

Abstract

The invention discloses a hybrid power device and a vehicle. The hybrid power device includes an engine, a first motor, a second motor, a first planetary row, a second planetary row, a first brake and a second brake, a first sun gear It is connected with the second planet carrier, the first planet carrier is connected with the second ring gear; the first input shaft is connected with the first sun gear, and the second input shaft is respectively connected with the first motor and the first ring gear; the first brake is set as a lock The first ring gear is locked or released, the second brake is set to lock or release the second planet carrier; the engine is set to be selectively engaged or disconnected with the first input shaft and the second input shaft, and the second The sun gear is connected, and the second ring gear is arranged to transmit power to the wheels. The hybrid power device according to the embodiment of the present invention adopts a double planetary row structure, which can realize compound power splitting and output power splitting, can realize various pure electric and hybrid driving modes, and is beneficial to improve fuel economy.

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
