Problems solved by technology

[0003] As the core component of electric vehicles, the drive motor has its unique features. Compared with traditional industrial motors, it requires more reliability, because it directly affects the normal driving of the car and personal safety. The resolver is used as the rotor position sensor of the drive motor due to Its rotor and stator are split structures. During installation, the rotor of the resolver is fixedly connected to the rotor of the drive motor, and the stator of the resolver is fixedly connected to the stator of the drive motor. There is axial movement, which will cause the position detection signal of the resolver to be distorted

Embodiment Construction

[0015] see figure 1 , figure 2 In this embodiment, the electric vehicle drive motor resolver positioning mechanism is to set a bearing gland 1 on the motor rotor 2, and fix the motor bearing 3 to the bearing seat of the motor rear end cover 4 through the bearing gland 1 and the gland screw 5 middle.

[0016] In specific implementation, before the motor bearing 3 is press-fitted, the bearing gland 1 is set on the rotor shaft 2, and then the motor bearing 3 is cold-pressed onto the rotor shaft 2 of the drive motor, and the resolver rotor 10 passes through the resolver rotor pressure plate 8 and The resolver rotor pressure plate fixing screw 9 is fixed on the tail end of the rotor shaft 2, so that the resolver rotor 10 is installed on the motor rotor; the resolver stator 7 is fixed on the drive motor through the resolver stator pressure plate 11 and the resolver stator pressure plate fixing screw 6 On the stator rear end cover 4, after the resolver stator 7 and the resolver ro...

Abstract

The invention discloses an electric mobile drive motor rotary transformer locating mechanism which is characterized in that a bearing press cover is arranged on a motor rotor. A motor bearing is fixed on a bearing seat of a motor rear end cover through the bearing press cover and a press cover screw. According to the electric mobile drive motor rotary transformer locating mechanism, a stator and the rotor of a rotary transformer can be axially located accurately so that accurate detection of a position signal can be guaranteed.

Description

technical field [0001] The invention relates to a positioning mechanism for a rotary transformer of an electric vehicle drive motor, which is used to ensure the axial positioning of the rotary transformer. Background technique [0002] With the further increase of global car ownership, the energy crisis, environmental pollution and global warming have become increasingly prominent, and new energy vehicles, especially electric vehicles, have become the focus of the development of domestic and foreign automobile companies. No matter from the perspective of environmental protection or energy, electric vehicles need a big development in the future, and its development will be related to the rise and fall of many industries, and may become a new economic growth point in the future. In my country, electric vehicles have a unique market, and there are very serious traffic problems and vehicle exhaust pollution problems in metropolises. As a small, medium-speed and short-distance d...
