Definitions
- the present invention relates to a suspension unit for ag ⁇ ricultural rollers, intended to provide elastic connection of the roller frame to a roller set including a shaft and roller rings.
- Such suspension units are already known. They have the ob ⁇ ject of permitting movement in the vertical plane for a roller set so that the roller set can adjust itself to ir ⁇ regularities in the ground during work with the roller when the latter has several sections.
- Figure 1 il ⁇ lustrates the unit from one side and Figure 2 is a perspec ⁇ tive view seen from one side.
- the numeral 1 denotes a roller, 2 the frame of the roller and 3 an attachment on an outer housing 4.
- the numeral 5 denotes an inner mounting carrying the outer end of the shaft of the roller set.
- the numeral 6 denotes two elastic rubber abutments connecting the housing 4 to the inner mounting 5 such that the inner mounting can move inside the outer housing 4 when the roller is in operation. Openings 7 and 8 are made respectively on the upper sides and under sides of the abutments 6. In this way the stiff- ness of the unit will be less vertically than horizontally.
- the roller set can then adapt to ground irregularities without any great movement taking place in the travelling direction.
- a ridge can be formed at the upper side of the inner mounting 5, this ridge coming into contact with the inner surface of the outer housing 4 after a given movement of the inner mount ⁇ ing 5.
- This ridge can to advantage be made cuneiform to obtain progressive force.
- the elastic material By placing the inner mounting 5 eccentrically and below the centre of the outer housing 4, the elastic material may be allowed to form a thicker layer between the inner mounting 5 and the ridge 9. There is thus obtained a larger elastic volume between the inner mounting and the ridge so that larger shock energy can be taken up in the movement of the inner mounting 5 towards the housing 4.
- rollers having several sections where outer sections are folded upwards during transport to re ⁇ cute the transport width
- the opening 7 may be given a V-shape with the apex directed downwards.
- the ridge 9 can be dispensed with.
- the abutments may have shape of two or more pairs having openings in between the pairs.
