Claims (2)
前記入力軸に対して平行に配置され駆動車輪側に連結される出力軸と、
前記入力軸から出力軸への動力伝達をなす少なくとも一組のギヤを備えたモータ用駆動装置であって、
前記モータ軸の出力側端と前記入力軸の入力側端とを同軸に保持してモータの駆動力を前記入力軸に伝達できるように接続させる接続部と、
該接続部をモータハウジングに対して回転自在に支持するベアリングとを備え、
さらに、前記少なくとも一組のギヤは、前記入力軸に駆動力が伝達されるときに、該入力軸の軸方向で前記モータハウジング側にスラスト力が発生するように構成されるヘリカルギヤで形成され、
前記入力軸は、該入力軸に発生したスラスト力を前記ベアリングのインナーレースに作用させる作用部を有し、該インナーレースに作用した前記スラスト力は前記ベアリングのアウターレースを介して前記モータハウジングに作用する、ことを特徴とするモータ用駆動装置。An input shaft coupled to the motor shaft of the vehicle drive motor;
An output shaft arranged in parallel to the input shaft and connected to the drive wheel side;
A motor drive device comprising at least one set of gears for transmitting power from the input shaft to the output shaft,
A connecting portion that coaxially holds the output side end of the motor shaft and the input side end of the input shaft so as to transmit the driving force of the motor to the input shaft;
A bearing that rotatably supports the connecting portion with respect to the motor housing;
Furthermore, at least one pair of gears, when the driving force is transmitted to the input shaft, a thrust force in the axial direction on the motor housing side of the input shaft is formed by a helical gear configured to generate ,
The input shaft has a working portion that causes a thrust force generated on the input shaft to act on the inner race of the bearing, and the thrust force acting on the inner race is applied to the motor housing via the outer race of the bearing. A motor drive device characterized by acting.
前記少なくとも一組のギヤのうち前記入力軸に配置されるギヤは、第１ベアリング近傍に配置され、
さらに、前記第１ベアリングは、入力軸方向のスラスト力が作用しないように配置されることを特徴とする、請求項１に記載のモータ用駆動装置。The drive device includes a first bearing that supports an end of the input shaft opposite to the motor housing, and a second bearing that supports an end of the input shaft on the motor housing;
Gear disposed on said input shaft of said at least one set of gears is disposed in the first bearing near
2. The motor drive device according to claim 1, wherein the first bearing is disposed so that a thrust force in an input shaft direction does not act. 3.
