Hybrid Power Plants and Vehicles

Abstract

The invention discloses a hybrid power device and a vehicle. In the hybrid power device, the first planetary row includes the first sun gear, the first planetary gear, the first ring gear and the first planet carrier, and the second planetary row includes the first Two sun gears, the second planetary gear, the second ring gear and the second planet carrier, the first sun gear is connected to the second planet carrier, the first planet carrier is connected to the second ring gear; the first input shaft is connected to the first planet carrier connection, the second input shaft is respectively connected to the first motor and the first ring gear; the first brake is set to lock or release the first ring gear, and the second brake is set to lock or release the second ring gear; the engine is set to be optional is selectively engaged or disconnected from the first input shaft and the second input shaft, the second motor is connected with the second sun gear, and the second planet carrier is configured to output power to the wheels. According to the hybrid power device of the embodiment of the present invention, the composite power splitting and the output power splitting are realized, which is beneficial to fuel economy, and realizes parking power generation, driving power generation, and the like.

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. All of the related technologies adopt a single planetary row structure, which can only realize the separation of single-mode hybrid power; 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 at high speed, the first motor reverses to provide power, and the second motor generates electricity, resulting in electric power circulation, with low efficiency; the...

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
