る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A cooling device for a drive motor according to an embodiment of the present invention is shown in FIG. The drive motor 1 is composed of a rotor 2, a stator 3, a motor housing 4, a plurality of annular cooling fins 5 provided on the surface of the motor housing, and the like.
Further, a duct 6a for accommodating the drive motor 1 and serving as a passage for the cooling air is arranged close to the drive motor, and the duct has a structure in which the cooling air is made to flow by the cooling fan 8 and exhausted from the other outlet of the duct. ing. In the present invention, in this cooling device, the cooling air guide member 9 is attached to the outer peripheral end surfaces of the plurality of annular cooling fins from the closest portion of the outer peripheral portion of the annular cooling fin 5 and the duct inner surface 6a toward the outflow direction of the cooling air. The air passage in the outflow direction of the cooling air is narrowed at the closest portion between the annular cooling fin 5 and the inner surface 6a of the duct, and the cooling air guiding member 9 is provided.
The cooling air passage formed by the annular cooling fin 5 and the motor housing 4 forcibly guides the cooling air sent from the cooling fan 8 to the rear portion of the annular cooling fin. For this reason,
The motor is cooled not only in the front annular cooling fin but also in the entire peripheral portion of the annular cooling fin, so that the drive motor can be efficiently cooled. When the vibration suppressing member having the vibration suppressing action is used for the cooling air guide member 9, the effect of suppressing the vibration of the annular cooling fin and reducing the noise of the drive motor is produced. As the vibration suppressing member, a rubber-based material, an asphalt-based material, a composite material of a metal such as an aluminum sheet and a rubber-based or asphalt-based material, or the like can be applied. Further, a synthetic resin member, a metal member, or the like can be applied as the cooling air guide member, and conventional fixing construction methods such as an adhesive, an adhesive, and a screwing method are not particularly restricted as a method of mounting the cooling air guide member. The cooling air guide member 9 can be mounted at any angle from the outermost portion of the annular cooling fin 5 and the innermost portion of the duct toward the cooling air outflow direction, which is effective, but the mounting range is 50 °. Most effective when the angle is set to 70 °. By improving the cooling efficiency,
A cooling fan having a smaller capacity than before can be used, and effects such as fan noise reduction and production cost reduction are produced.

よい。FIG. 2 is a diagram showing a cooling device for a drive motor according to another embodiment of the present invention. 2 is different from the conventional cooling device shown in FIG. 4 in the cooling air outflow direction from the outermost portion of the annular cooling fin 5 and the closest portion of the duct inner surface 6a.
A cooling air guide member 9 is installed in the duct 6a or 6b so as to close the air passage in the vicinity of the outer peripheral portions of the plurality of annular cooling fins 5. By this cooling air guide member 9, the cooling air reaches the rear portion of the annular cooling fin 5 and the cooling efficiency is improved as in the cooling device shown in FIG. It is desirable that the mounting position of the cooling air guide member 9 be as close as possible to the annular cooling fin 5. Further, it is desirable that the gap between the ducts 6a and 6b and the cooling air guide member 9 be as narrow as possible so that the cooling air does not easily pass through. The width L of the cooling air guide member 9 may be in the range shown in FIG.

準ずる。FIG. 3 is a diagram showing a cooling device for a drive motor according to still another embodiment. The cooling efficiency is improved by changing the shape so as to narrow the duct 6a close to the annular cooling fin in the outflow direction of the cooling air from the outermost portion of the annular cooling fin 5 and the closest portion of the duct inner surface 6a. The dimensions and the like of the duct narrowing portion are in accordance with the cooling air guide member 9 shown in FIGS.

ことができる。According to the present invention, since the cooling air reaches the rear portion of the annular cooling fin in the cooling device, the cooling efficiency of the drive motor can be improved. Further, as the cooling efficiency is improved, the cooling fan can be downsized, which can reduce noise and production cost. Further, if the cooling air guide member arranged on the outer peripheral portion of the annular cooling fin is constituted by the vibration suppressing member, the vibration of the annular cooling fin can be suppressed and the noise can be reduced.
