<p>Forming part of a spring suspension system for a wheel (1) are telescopically disposed outer and inner parts (5, 6), which are reciprocally displaceable along their longitudinal axes (41). The parts can be exposed to reciprocal transverse forces (F) directed towards the longitudinal axes, at the same time as which the functioning of the spring suspension system is expected to be exercised. A bearing bush (34) between the parts is disposed in a position-variable manner, with a view to ensuring expedient longitudinal displacement movements between the parts (5, 6), in spite of the said transverse forces. The sliding function between means (20) promoting the parts is disposed such that it can be supplied from the top side (13a) of the bearing bush. One or more channels (32), leading from the top side (13a) of the bearing bush to its bottom side (13b), enable a medium to be supplied to the said bottom side. In the event of compression movement between the parts, an underpressure is generated at the bottom side of the bearing bush, which underpressure is used to ensure that the medium is supplied to the bottom side (13b) of the bearing bush.</p> |
