Multipurpose combined machine

Combined machine, comprising:

• a motor (M);
• a plurality of operating machines (H, C, V) that can be powered in an independent manner by said motor;
• a transmission box (1), placed between the motor (M) and said operating machines (H, C, V),
• said transmission box comprising i) an inlet shaft (3) connected to said motor (M), ii) a plurality of outlet shafts (4a-4c) configured for connecting respectively to corresponding ones of said operating machines (H, C, V), iii) a freewheel bearing (5a-5c) associated with each outlet shaft, each outlet shaft (4a-4c) driven by a corresponding one of the freewheel bearings, and iv) a plurality of gear wheels (8a-8c) connected to the outlet shafts by the freewheel bearings,
• each freewheel bearing having an internal ring fixed to the corresponding outlet shaft and an external ring fixed to the corresponding gear wheel,
• said inlet shaft and said outlet shafts aligned in a common direction to connect said motor selectively to respective ones of said operating machines,
• in operation, the gear wheels are always engaged and always rotate with mechanical power transferred to the selected outlet shaft only in an engaging direction of the corresponding freewheel bearing, with remaining ones of the gear wheels rotating idle on the respective shafts thereof;
• and
• a reversing device (S, D) for selectively reversing the rotation direction given by said motor (M) to said inlet shaft (3) of the transmission box (1) and thereby selectively inverting the rotational direction of the gear wheels.

Combined machine, comprising:

• a single direction motor;
• a plurality of operating machines selectively powered in an independent manner by said motor;
• a transmission box, located between the motor (M) and said operating machines,
• said transmission box comprising i) an inlet shaft connected to said motor, ii) a plurality of outlet shafts, each outlet shaft configured for connecting respectively to a corresponding one of said operating machines, iii) a freewheel bearing on each outlet shaft, each outlet shaft driven by a corresponding one of the freewheel bearings, and iv) a plurality of gear wheels connected to the outlet shafts by respective ones of the freewheel bearings,
• each freewheel bearing having an internal ring fixed to the corresponding outlet shaft and an external ring fixed to a corresponding gear wheel,
• said inlet shaft and said outlet shafts aligned in a common direction,
• in operation, the gear wheels are always engaged and always rotate with mechanical power transferred to the selected outlet shaft only in an engaging direction of the corresponding freewheel bearing, with remaining ones of the gear wheels rotating idle;
• and
• a reversing device (S, D) for selectively reversing the rotation direction given by said motor (M) to said inlet shaft (3) of the transmission box (1) and thereby selectively inverting the rotational direction of the gear wheels.
