Hybrid electric vehicle power system based on magnetic transmission

Abstract

The invention discloses a hybrid electric vehicle power system based on magnetic transmission. The hybrid electric vehicle power system comprises elements such as a spline shaft sleeve and an engine permanent magnet turntable, the engine permanent magnet turntable is sleeved on a rotation shaft of a middle turntable and is connected together with an engine through the spline shaft sleeve, a motor permanent magnet turntable is also sleeved on the rotation shaft of the middle turntable and is connected with a motor through a straight-tooth transmission gear and a motor gear, high-energy permanent magnets are mounted on the engine permanent magnet turntable and the motor permanent magnet turntable, a first copper ring and a second copper ring are mounted on the left side and the right side of the middle turntable, the first high-energy permanent magnet and the first copper ring form a first magnetic coupling system, and the second high-energy permanent magnet and the second copper ring form a second magnetic coupling system. The hybrid electric vehicle power system has the advantages of simple structure, control accuracy, convenience in maintenance, high reliability and the like.

Description

technical field [0001] The invention relates to a power system, in particular to a hybrid electric vehicle power system based on magnetic drive. Background technique [0002] The power system of a hybrid electric vehicle is one of the key systems of a hybrid electric vehicle, which has functions such as pure electric driving, power coupling and distribution, and braking energy recovery. There are two main types of hybrid electric vehicle power systems currently in use: [0003] 1. Planetary gear power system. Currently, this type of system is widely used in Toyota Prius hybrid cars. Its fuel economy, power and driving stability are relatively good, but its structure is complex and requires high machining accuracy for parts. The cost is also high. [0004] 2. ISG (Integrated Starter and Generator) power system, whose power motor is integrated between the engine and gearbox, is currently used in vehicles such as Honda Insight. This type of system has the advantages of simple...

[0003] 1. Planetary gear power system. Currently, this type of system is widely used in Toyota Prius hybrid cars. Its fuel economy, power and driving stability are relatively good, but its structure is complex and requires high machining accuracy for parts. high cost

[0004] 2. ISG (Integrated Starter and Generator) power system, whose power motor is integrated between the engine and gearbox, is currently used in vehicles such as Honda Insight. This type of system has the advantages of simple structure and low cost, but It doesn't mix well and does little to help fuel economy
