Double-solid-shaft motor single planet row hybrid power system

Abstract

The invention relates to a double-solid-shaft motor single planet row hybrid power system. The double-solid-shaft motor single planet row hybrid power system comprises an engine, a first motor, a second motor, a sun wheel, a planet wheel, a planet carrier, a gear ring, a first motor driving gear, a first motor driven gear, a second motor driving gear, a second motor intermediate shaft driven gear, a second motor intermediate shaft driving gear, a second motor driven gear, a first motor driving gear shaft, a first motor driven gear shaft, a second motor driving gear shaft, a second motor intermediate shaft, a second motor driven gear shaft and a planet carrier shaft. Compared with the prior art, the first motor and the second motor are solid shaft motors, the structure is simple, the motors are easy to machine and manufacture, the problems that due to the fact that a motor MG1 and a motor MG2 in the prior art are hollow shaft motors, the structures of the motors are complex, and the motors are difficult to machine and manufacture are solved, cost is reduced, and a box body is easy to seal.

Description

Technical field [0001] The invention relates to a power system of a hybrid vehicle, in particular to a dual solid shaft motor single planetary row hybrid power system. Background technique [0002] Hybrid electric vehicles are a practical solution to energy and environmental issues at this stage. However, the existing dual-motor planetary hybrid power system has certain defects. [0003] Chinese patent ZL200480019795.5 discloses a power output device for a hybrid vehicle. The hybrid vehicle of this invention has an internal combustion engine, a planetary gear unit including a planetary carrier connected to the crankshaft of the engine and a ring gear connected to the drive shaft, The sun gear of the gear unit inputs power and a motor (MG1) that outputs power from the sun gear, and a motor (MG2) that inputs power to and outputs power from the drive shaft. Through analysis, it is found that the invention has the following defects: Because the motors MG1 and MG2 are both hollow shaf...

AI Technical Summary

Problems solved by technology

Through analysis, it is found that the invention has the following defects: since the motor MG1 and the motor MG2 are both hollow-shaft motors, the structure of the motor becomes complicated, which increases the difficulty of processing and manufacturing the motor, thereby increasing the cost and increasing the size of the box. Difficulty of sealing
