<p>PROBLEM TO BE SOLVED: To provide a coupling body structure provided with a friction coupling in which danger of overheat is reduced to achieve a longer service life as a result of it. SOLUTION: This coupling body structure for agricultural machinery comprises a friction coupling 1, an electromagnet 6, and a control means 7. The friction coupling 1 comprises a friction body structure 4 loaded by a compression plate 14 loaded by compression springs 15, 16 in order. The compression plate 14 is adjustable by an actuation device 5 comprising the electromagnet 6 and a mooring plate 19. The control means 7 comprises a control member 27 to adjust compression force of the compression plate 14 during coupling and/or coupling releasing actuation by changing a current. A housing 2 and a hub 3 are linked with speed sensors 25, 26, and the speed sensors 25, 26 transmit signals to the control member 7 for reducing load on the friction body structure 4, thereby overheating of the friction coupling 1 can be prohibited.</p> |
