Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment belongs to the scope of protection of the invention.
- 2 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of special non-brush permanent-magnet DC motor of electric vehicle,
Including housing 1, the outer wall of the housing 1 is enclosed with acoustical cotton layer 2, and the outer wall of the acoustical cotton layer 2 is enclosed with protective shell 3, institute
The right side for stating housing 1, acoustical cotton layer 2 and protective shell 3 is inlaid with one group of bearing 4, and the inner cavity of the bearing 4 has extended transversely through transmission
Bar 5, the left end of the drive link 5 is connected with polygonal column 6, and polygonal column 6 is located at the inner cavity of housing 1, the left side of the polygonal column 6
Shaft 10 is connected with, electric telescopic rod 7 is mounted at the top and bottom of 1 inner cavity of housing, and two groups of electric telescopic rods 7 are equal
With polygonal column 6 in same vertical centerline, the lateral expansion end of the electric telescopic rod 7 is equipped with to be adapted with polygonal column 6
Fixing card 8, the left side of the housing 1, acoustical cotton layer 2 and protective shell 3 is uniformly provided with heat emission hole 9, the shaft 10 it is outer
Wall is evenly arranged with permanent-magnet pole 11, and the inner wall of the housing 1 is evenly arranged with the coil windings 12 being adapted with permanent-magnet pole 11.
Wherein, bonded together between the housing 1, acoustical cotton layer 2 and protective shell 3 by adhesive, it is steady to increase connection
Qualitative, the protective shell 3 is steel protective shell, and hardness is high, is unlikely to deform, is bonded with and fills out between permanent-magnet pole 11 described in two adjacent groups
Item is filled, and the inside of packing is connected with the outer wall of shaft 10, it is more stable when rotating permanent-magnet pole 11.
Operation principle：Shaft 10 and permanent-magnet pole 11 form rotor, and housing 1 forms stator, coil windings with coil windings 12
