Description

また、操舵側前輪駆動機構５０ｂは、サイドフレーム１４（図４）の下面に取り付けられた駆動モータ５２ｂと、駆動モータ５２ｂの出力軸に接続されたドライブジョイント５４ｂと、略Ｘ軸方向に延びる入力軸の回転を略Ｙ軸方向に延びる出力軸の回転に変換する等速ベベルギヤ装置５６ｂとを備える。等速ベベルギヤ装置５６ｂの出力軸は、ファイナルケース５７内に保持されたピニオン５７ａの入力軸に接続される。ピニオン５７ａの回転は、ギヤ５７ｂに伝達されることで減速される。また、ピニオン５７ａとギヤ５７ｂから構成される操舵側ファイナルギヤの減速比は、減速ベベルギヤ装置５６ａの減速比と同一の値に設定されており、ギヤ５７ｂは、制動側前輪駆動機構５０ａ及び操舵側前輪駆動機構５０ｂにより同一の速度で駆動される。また、上述のように、ギヤ５７ｂの出力軸には複数のスタッドボルトが植え込まれており、前輪ホイール７ａに設けられた複数のボルト穴に各スタッドボルトを挿し込み、ホイールナット７ｂで締め付けることにより、前輪ホイール７ａがギヤ５７ｂの出力軸に固定される。 Further, the steering-side front wheel drive mechanism 50b includes a drive motor 52b attached to the lower surface of the side frame 14 (FIG. 4), a drive joint 54b connected to the output shaft of the drive motor 52 b, extending substantially X-axis direction A constant-velocity bevel gear device 56b that converts the rotation of the input shaft into the rotation of the output shaft extending substantially in the Y-axis direction. The output shaft of the constant velocity bevel gear device 56 b is connected to the input shaft of the pinion 57 a held in the final case 57. The rotation of the pinion 57a is decelerated by being transmitted to the gear 57b. Further, the reduction ratio of the steering side final gear composed of the pinion 57a and the gear 57b is set to the same value as the reduction ratio of the reduction bevel gear device 56a, and the gear 57b includes the braking side front wheel drive mechanism 50a and the steering side. Driven at the same speed by the front wheel drive mechanism 50b. As described above, a plurality of stud bolts are implanted in the output shaft of the gear 57b, and the stud bolts are inserted into a plurality of bolt holes provided in the front wheel 7a and tightened with the wheel nuts 7b. Thus, the front wheel 7a is fixed to the output shaft of the gear 57b.
