- 機体にカッターブレードと、走行輪と、この走行輪を駆動する駆動源と、前記駆動源によって回転駆動される駆動ギヤと、前記走行輪が左右端に固定され、前記機体に回転自在に支持された車軸と、前記車軸に回転可能に設けられ、前記駆動ギヤに噛み合う従動ギヤと、前記駆動源と前記走行輪との間の動力伝達系に介在した噛合いクラッチと、前記噛合いクラッチを切り換えるクラッチ切換え機構とを備え、
前記噛合いクラッチは、入力側の噛合い爪を有した入力側半体と、出力側の噛合い爪を有した出力側半体とからなり、
前記入力側の噛合い爪が周方向における正回転側において周方向に対して直交する入力側直交面と、周方向における逆回転側において周方向に対して傾斜する入力側傾斜面とを備え、
前記出力側の噛合い爪が前記入力側傾斜面に対向する出力側傾斜面と、前記入力側直交面に対向する出力側直交面とを備え、
前記クラッチ切換え機構は、
前記入力側半体に設けられた軸線方向に突出し、周方向に対して傾斜する傾斜面を有する突起部と、前記従動ギヤに設けられ、前記突起部を受容し、前記傾斜面に正回転時に当接する角を有する凹部とを含み、
前記駆動源が正回転したときには、前記駆動源の動力によって前記噛合いクラッチをオンに切り換え、
前記駆動源が逆回転したときには、前記駆動源の動力によって前記噛合いクラッチをオフに切り換える歩行型芝刈機において、
前記駆動源は、電動モータによって構成され、
当該歩行型芝刈機は、操作スイッチと、この操作スイッチのスイッチ信号に従って前記電動モータを制御する制御部とを更に備え、
この制御部は、前記操作スイッチからモータ停止操作信号を受けたときに、前記噛合いクラッチをオフに切り換えるべく、前記電動モータを逆転するように制御する構成であることを特徴とする歩行型芝刈機。 - 前記電動モータを逆転する時間は、少なくとも前記噛合いクラッチのオン状態からオフ状態に切り替わるまでの時間に設定されていることを特徴とする請求項1記載の歩行型芝刈機。
- 前記制御部は、前記電動モータに通電される電流値の変化に従って、前記電動モータを逆転する時間を決定することを特徴とする請求項2記載の歩行型芝刈機。
- 前記出力側半体が前記車軸に同軸に固定され、
前記入力側半体が前記車軸に同軸に回転自在に設けられ、
前記駆動源の動力によって、前記従動ギヤが回転し、前記従動ギヤの前記凹部の前記角が前記入力側半体の前記突起部の前記傾斜面に当接することで、前記入力側半体が前記出力側半体に向けて変位し、
前記駆動源が正回転したときには、前記入力側直交面と前記出力側直交面とが互いに当接することで、前記噛合いクラッチがオンとなることを特徴とする請求項1〜請求項3のいずれか1つの項に記載の歩行型芝刈機。 - 前記駆動源が逆回転したときには、前記入力側傾斜面と前記出力側傾斜面とが互いにスライドすることによって、前記入力側半体と前記出力側半体とが互いに離反し、前記噛合いクラッチがオフとなることを特徴とする請求項1〜請求項4のいずれか1つの項に記載の歩行型芝刈機。
