Hybrid Power Plants and Vehicles

Abstract

The invention discloses a hybrid power device and a vehicle. The hybrid power device includes a first planetary row and a second planetary row, the first sun gear is connected with the second sun gear, and the first ring gear is connected with the second planet carrier. the engine is arranged to selectively engage or disengage the input shaft, the input shaft is arranged to selectively engage or disengage the first sun gear and the first planet carrier; the first brake is arranged to lock or release the second sun gear , the second brake is set to lock or release the second ring gear, the third brake is set to lock or release the input shaft; the first motor is connected to the second ring gear, the second motor is connected to the second sun gear, the first gear The rings are configured to output 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
