Description

Technical Field

[0001] The utility model relates to an automobile motor, and more specifically, to a rotor of a steering motor for an automobile. Background Art

[0002] In existing automotive steering applications, these steering motors all have a stator assembly and a rotor assembly. The rotor typically refers to a rotating body supported by bearings. Objects without a rotating shaft, such as optical disks, are considered a rotor when rigidly connected or with an attached shaft. In a motor, the rotor and stator work together to convert electrical energy into mechanical energy.

[0003] During the use of automobile steering motors, the motors require good sealing effects. In order to improve the sealing of the rotor, a large number of sealing components need to be used to seal the rotor during the installation process. This leads to relatively high processing requirements for the motor during processing and great processing difficulty. At the same time, the overall flame retardant effect of the motor is low.

[0016] 2. The magnetic slots of different columns are arranged in a stepped manner from top to bottom to adjust the slip rate of the motor. By optimizing the slip rate, the overall performance and operating efficiency of the motor can be improved.

[0017] 3. The magnetic sheet is driven to be set in the contact area by the positioning ribs, and the adhesive groove drives the adhesive to cooperate with the magnetic sheet to achieve the fixation of the magnetic sheet and the rotor core, thereby improving the fixing effect of the magnetic sheet.

[0018] 4. The shell is made of aluminum or zinc to avoid electromagnetic interference and magnetic field leakage, ensuring the normal operation of the rotor.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Figures 1 to 3As shown, the utility model provides a technical solution: a rotor of a steering motor for an automobile, having a rotating shaft 1, the axis of the rotating shaft 1 being the rotating axis of the motor, and a bearing 5 is interference-fitted on both sides of the rotating shaft 1 extending to the rotor core 2.

[0026] The rotating shaft 1 can rotate well under the action of the bearing 5. The rotating shaft 1 is provided with a driving part, and the driving part is interference-fitted with a driving component.

[0027] The driving component mainly drives the steering system of the vehicle to work. The rotor of the steering motor for the vehicle includes: a rotor core 2, which is made of a plurality of single iron sheets stacked together.

[0028] In addition, the rotor core 2 is provided with multiple columns 201 from top to bottom along the rotating axis 1 line, and each column 201 is provided with multiple magnetic slots 202 around the rotating axis 1 line. The magnetic slots 202 of different columns 201 are arranged in a stepped manner from top to bottom. This is mainly because the columns 201 are rotated from top to bottom by a specified angle when being laid out, so that the magnetic slots 202 on the same side are arranged in a stepped manner. This is mainly to generate a rotor slope, thereby adjusting the slip rate of the motor. By optimizing the slip rate, the overall performance and operating efficiency of the motor can be improved.

[0029] Magnetic sheets 3 are arranged in a one-to-one correspondence in the magnetic groove 202. The magnetic groove 202 includes: two parallel positioning ribs and a contact area arranged between the two positioning ribs. The contact area is provided with an adhesive groove 203 that cooperates with the magnetic sheet 3. The magnetic sheet 3 is first positioned by the two positioning ribs, and then fixed with the adhesive groove 203 to improve the fixing effect of the magnetic sheet 3.

[0030] The rotor core 2 and the magnetic sheet 3 are integrally wrapped with an enclosure 4, which is made of aluminum or zinc. The aluminum or zinc enclosure prevents electromagnetic interference and magnetic field leakage, ensuring the normal operation of the rotor.

[0031] The enclosure 4 can also be formed by integral die-casting to enclose a non-magnetic shell disposed outside the core and the magnetic tiles. Using integral die-casting to enclose a non-magnetic shell disposed outside the core and the magnetic tiles improves the overall sealing of the rotor, reduces processing difficulty, simplifies processing steps, and improves the securing effect of the magnetic sheet 3. It also prevents electromagnetic interference and magnetic field leakage, ensuring the normal operation of the rotor.

[0032] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
