Summary: | To provide a connection structure which achieves excellent working efficiency in work of connecting a suspension device side bracket to a casing of an in-wheel motor drive device with multiple bolts.SOLUTION: An in-wheel motor drive device includes: a wheel hub bearing part; a motor part; a casing which houses a rotation transmission path from a motor rotary shaft of the motor part to a rotary wheel of the wheel hub bearing part; a bracket part 17m which may be coupled to a suspension device; and fixing means which fixedly attaches the bracket part to the casing 29. The fixing means has: bracket through holes 17h, 17h formed at the bracket part 17m; casing through holes 46, 46 which are formed at the casing 29 and respectively connected to the bracket through holes; bolts 47 which penetrate through the respective bracket through holes 17h and the respective casing through holes 46 connected with each other; and a female screw member 48 including at least two female screws 48f which threadedly engage with the respective bolts.SELECTED DRAWING: Figure 5
【課題】サスペンション装置側のブラケットを複数のボルトでインホイールモータ駆動装置のケーシングに連結する作業において、作業効率に優れる連結構造を提供する。【解決手段】インホイールモータ駆動装置は、車輪ハブ軸受部と、モータ部と、モータ部のモータ回転軸から車輪ハブ軸受部の回転輪までの回転伝達経路を収容するケーシングと、サスペンション装置と連結可能なブラケット部17mと、該ブラケット部をケーシング29に取付固定する固定手段とを備える。固定手段は、ブラケット部17mに形成される複数のブラケット貫通孔17h,17hと、ケーシング29に形成されて複数のブラケット貫通孔にそれぞれ接続する複数のケーシング貫通孔46,46と、互いに接続する各ブラケット貫通孔17hおよび各ケーシング貫通孔46を貫通するボルト47と、複数のボルトのそれぞれと螺合する雌ねじ48fを少なくとも2個含む雌ねじ部材48を有する。【選択図】図5 |
