Suspension fork sealhead for increased component lubrication

Abstract

The present disclosure provides a suspension fork comprising a fork leg comprising an upper tube and a lower tube slidably engaged with one another for compression and rebound, a damper assembly positioned within the fork leg, the damper assembly comprising a shaft and a sealhead coupled to the shaft, and a reservoir configured to retain bath oil in proximity to the sealhead. The sealhead is sized and positioned to splash bath oil upwards when the sealhead is driven into the bath oil during the compression of the suspension fork. The sealhead comprises a base portion and a leading portion tapering downwards from the neck. The hydrodynamic profile of the sealhead creates controlled oil displacement patterns that distribute lubricating oil to internal components including bushings, seals, and sliding surfaces during suspension movement.
