Alternate rotational driving mechanism for two driven shafts comprises sleeve rotating with driving shaft by runner allowing selective displacement in one of two directions and coupling of dogging means with driven shafts' gearing

摘要

The driving mechanism comprises a dogging sleeve (1) connected to rotate with the driving shaft (A1) by means of a connecting runner (2). This allows its selective displacement by means of a fork selector (3) in one of two directions, concomitantly with the coupling of the dogging means (4a,4b) located either side the sleeve with gearing (5,6) integral with the driven shafts (A2,A3).
