Abstract
Disclosed is a driving motor for water-cooled electric automobiles, comprising an outer gasket ring, a shell, a stator, a rotor, a front end closure, a rear end closure and two bearings. The rotor is supported by the two bearings respectively arranged on the front end closure and the rear end closure which are fixed at two ends of the shell through bolts. The stator is pressed on the inner circle of the shell. The driving motor is characterized in that a spiral trough is processed on the outer circle of the shell and the outer gasket ring is hinged at the outer circle of the shell to enable the spiral trough to develop into a spiral watercourse. Cooling water flows in from a water inlet at the outer gasket ring and runs along the spiral watercourse on the shell to cool the motor and then flows out from a water outlet at the outer gasket ring. Compared with conventional art, the driving motor is good in heat dissipation effect, large in power, simple in process and reliable in performance.
Description
Technical field
The utility model relates to motor with watter cooling, is particularly useful for the drive motor of electric automobile.
Background technology
Along with the exhaustion day by day of world petroleum resource and the severe exacerbation of environment, the electric automobile replacement of adopting clean energy resource is that the automobile of power has become inevitable with the incendiary oil.Drive motor is as " heart " of electric automobile, must satisfy specification requirements such as high-power, small size, high reliability.Present driving motor for electric automobile generally adopts structure air-cooled or by self cooling off.Because cooling fan can produce noise when work, and cooling effect is limited, can not reduce the volume weight of drive motors significantly; Drive motors volume by the self-radiating cooling is bigger, heavy more.So must adopt the more advanced rational type of cooling could reduce volume, the weight of drive motors significantly.
Summary of the invention
The utility model provides a kind of driving motor for electric automobile of water-cooling structure, can further reduce the volume and the weight reduction of drive motors, obtains bigger specific power.
The technical scheme that the utility model adopted is:
A kind of water cooled electrodynamic automobile drive electric motor is made up of exterior seal ring, casing, stator, rotor, front end housing, rear end cap and bearing.Rotor is by two bearing supportings that are contained on front end housing and the rear end cap, forward and backward end cap is by being bolted to the two ends of casing, stator press-loading is circle in casing, it is characterized in that: the cylindrical of casing is processed with the spirality tank, the cylindrical that exterior seal ring is welded on casing makes tank form the spirality channel of sealing, cooling water is flowed into by the water inlet on the exterior seal ring, is flowed out by the delivery port on the exterior seal ring after the spirality channel of process casing is given motor radiating.
In order further to dwindle stator dimensions, casing and exterior seal ring all adopt magnetic property preferably No. 10 steel process, as the part of stator yoke, so the yoke portion size of stator is little.
Beneficial effect:
1. because drive motors adopts water-cooling structure, good heat dissipation is so reliable operation, specific power are big.
2. exterior seal ring is the form that adopts welding with being connected of casing, and technology is simple, good seal performance.
3. casing so the yoke portion size of stator is little, has reduced the consumption of silicon steel sheet as the part of stator yoke, has reduced cost.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Sequence number explanation among the figure: 1. bolt, 2. rear end cap, 3. exterior seal ring, 4. water inlet, 5. spiral tank, 6. casing, 7. stator, 8. rotor, 9. delivery port, 10. front end housing, 11. bearings.
Embodiment:
Be described further below in conjunction with drawings and Examples:
The water cooled electrodynamic automobile drive electric motor mainly is made up of rear end cap 2, exterior seal ring 3, casing 6, stator 7, rotor 8, front end housing 10, bearing 11.Stator 7 is fitted in the interior circle of casing 6, front end housing 10 and rear end cap 2 are fixed on the two ends of casing 6 by bolt 1, rotor 8 is by two bearings, 11 supportings that are contained on front end housing 10 and the rear end cap 2, cylindrical at casing 6 is processed with spirality tank 5, the cylindrical that exterior seal ring 3 is welded on casing 6 makes the spirality tank form the spirality channel of sealing, cooling water is flowed into by the water inlet on the exterior seal ring 4, and the spirality channel of process casing 6 is flowed out by the delivery port on the exterior seal ring 39 after giving motor radiating.
In order further to dwindle stator dimensions, casing 6 and exterior seal ring 3 all are to be processed by No. 10 steel, as the part of stator yoke, so the yoke portion size of stator is little.
Claims (2)
1. a water cooled electrodynamic automobile drive electric motor is made up of exterior seal ring, casing, stator, rotor, front end housing, rear end cap and bearing; Rotor is by two bearing supportings that are contained on front end housing and the rear end cap, forward and backward end cap is by being bolted to the two ends of casing, stator press-loading is circle in casing, it is characterized in that: the cylindrical of casing is processed with the spirality tank, the cylindrical that exterior seal ring is welded on casing makes tank form the spirality channel of sealing, cooling water is flowed into by the water inlet on the exterior seal ring, is flowed out by the delivery port on the exterior seal ring after the spirality channel of process casing is given motor radiating.
