Abstract

The invention discloses an integrated high-speed cycloid hub motor, which includes a hub component, a motor component, a cycloid reducer component, and an output component. The motor component is arranged in the hub, and the motor component includes a motor casing, a motor inner casing, The central shaft, the rotor connected to the central shaft, and the stator matched with the rotor, the rotor is a cantilever structure, and a concave space is formed at one end, and the cycloidal reducer components are installed in the concave space. The central shaft is connected with the cycloidal reducer part as the input end of the cycloidal reducer part, and the other end of the cycloidal reducer part is connected with the output part, and the output shaft of the output part is fixedly connected with the hub part. The invention can provide sufficient torque and rotating speed of the automobile to ensure the adaptability to various complex working conditions; secondly, the integrated design of the cycloidal gear reducer and the motor reduces the excessive size of the gear reducer and makes the structure of the hub motor Compact and able to maintain high efficiency operation.

Description

technical field [0001] The invention belongs to the field of electric vehicles and motor manufacturing, relates to an integrated high-speed cycloid hub motor, and is suitable for driving devices of various electric vehicles. Background technique [0002] With people's increasing awareness of environmental protection and the gradual rise in international oil prices, consumers have increased their demand for green and non-polluting electric vehicles when buying cars; "Continuing to support the development of electric vehicles and fuel cell vehicles is to raise the development of electric vehicles above the national development strategy. Hub motor technology is one of the important three verticals in the research and development direction of the "three verticals and three horizontals" of electric vehicles. The research design is of great significance and is also in line with the national development strategy. [0003] In-wheel motor technology, also known as in-wheel motor tec...
