The power take-off (10) applied on industrial vehicles eliminates noisiness generated by play between cogs of transmission cogwheels (14,19) when the p.t.o. is functioning non-operatively. Thanks to a special geometry of the cog directions of the cogwheels (19, 14) in the transmission gearings, play between cogs is eliminated when there is no power transmission. The play is re-established when the p.t.o. is functioning operatively, by overcoming elastic (21) means acting axially on the gearings (14), and by thus returning the gearings (14) into a normal operative position. |
