Problems solved by technology

[0005] The present invention aims to solve the problem of limited space in existing automobiles and large axial dimensions of motors and transmissions. The motor adopts a hollow rotor, the transmission adopts a planetary row structure, and the speed change mechanism is placed inside the hollow rotor of the motor, which greatly reduces the motor and The axial size of the transmission, and the integrated structure of the motor and the transmission save materials and reduce the overall weight, which is conducive to the development of light weight and miniaturization of the whole vehicle

Embodiment Construction

[0019] The concrete implementation method of the present invention is as follows:

[0020] Nowadays, many cars are developing towards miniaturization and light weight. It is hoped to reduce the volume of the vehicle while ensuring the performance of the vehicle, and to leave as much space as possible. This affects the size of the vehicle-mounted devices and equipment. The requirements are getting higher and higher. In order to solve this problem, the present invention adopts a new integrated structure of motor and transmission. The motor adopts a hollow rotor, and the transmission adopts a planetary row structure. The transmission is placed inside the hollow rotor to realize the integration of the motor and the transmission. In this way, the axial size of the motor and transmission can be greatly reduced, the overall volume can be reduced, and materials can be reduced, which is conducive to the lightweight and miniaturization of the whole vehicle.

Abstract

The invention discloses a novel integrated structure of a motor and a transmission. The motor adopts a hollow rotor; the transmission adopts a planet row structure and is arranged in the hollow rotor. Therefore, the axial size is greatly reduced, the structure is more compact, and materials are saved and the whole weight is reduced due to the fact that the motor and the transmission are integrated.

Description

technical field [0001] The invention relates to an integrated structure of a motor and a transmission. technical background [0002] Nowadays, the requirements for light weight and miniaturization of vehicles are getting higher and higher, especially for hybrid vehicles, because of the addition of motors, controllers, and many electrical accessories on the basis of traditional fuel vehicles or natural gas vehicles. As a result, it is more difficult to reduce the weight and miniaturization of hybrid vehicles; for passenger cars, especially buses, due to the limited overall space of the vehicle, too much space occupied by the vehicle drive system will inevitably lead to a reduction in the space available for personnel. This is obviously not conducive to people's travel. [0003] Most of the existing methods to solve the problem of large axial dimensions of the motor and the transmission are to shorten the connecting shaft of the motor and the transmission as much as possible,...
