PCT No. PCT/SE87/00549 Sec. 371 Date Apr. 19, 1989 Sec. 102(e) Date Apr. 19, 1989 PCT Filed Nov. 20, 1987 PCT Pub. No. WO88/04133 PCT Pub. Date Jun. 16, 1988.A suspension unit in agricultural rollers, for elastically connecting the frame of the roller to a roller set including a shaft and a plurality of roller rings. An outer axially extending housing (4) is connected to the frame (2) of the roller (1) with the aid of an attachment (3). An inner mounting (5) carries the end of the roller set shaft. On either side of the inner mounting (5) there are axialy arranged horizontal abutments (6), of elastic material, e.g. rubber, connecting the housing (4) to the mounting (5). Through openings (7, 8) are formed at the upper side (7) and under side (8) of the inner mounting. There is thus obtained low stiffness vertically, and the inner mounting (5) is allowed large movement vertically, whereby the roller set is given great adaptability to ground irregularities. By having large stiffness in the horizontal direction, the roller set is only allowed small movement in the travelling direction of the roller. |
