Description
(a)左ハンドル仕様車両で、車両の直進中に、ラック軸に作用する路面反力により、ピニオン軸及びこれに固定のウォームホイールは一方向(B)に変位せしめられ、ウォームは反対方向(D)に変位せしめられる。即ち、ウォームホイールとウォームは、それらの変位前にそれらの間に存在していたがたを互いに減ずる方向に変位せしめられ、路面からの反力に原因するウォームギヤ式減速機構の振動は増幅されない。

Claims (1)
- ステアリングホイールに加えた操舵トルクをラックアンドピニオン機構のピニオン軸に伝えるとともに、前記操舵トルクに応じて電動モータが発生する補助トルクをウォームギヤ式減速機構を介して前記ピニオン軸に伝え、前記ラックアンドピニオン機構によって操舵輪を操舵するに際し、前記ピニオン軸に前記ウォームギヤ式減速機構のウォームホイールを固定した車両用電動パワーステアリング装置において、
車両の左席側にステアリングホイールを配置した左ハンドル仕様車両の車両正面視で、前記ピニオン軸に設けられるはすばピニオンのねじれ角の方向と、前記ウォームホイールの進み角の方向を逆方向にしたことを特徴とする車両用電動パワーステアリング装置。
