  • System for lubricating a pivot interface of a work vehicle
    Patent number: 10392058
    Abstract: A system for lubricating a pivot interface defined between adjacent components of a work vehicle may include a shaft and a shaft housing configured to receive an axial portion of the shaft such that the shaft housing is configured to rotate relative to the shaft. The system may also include an end cap installed relative to an end of the shaft housing and a sealing device configured to seal a radial gap defined between the shaft housing and the shaft at a seal location when a fluid pressure within the housing is below the seal's cracking pressure. Additionally, when the fluid pressure within the housing exceeds the cracking pressure, the sealing device may be configured to transition to an unsealed state to allow lubricant contained within the housing to flow axially between the sealing device and the shaft and be subsequently purged from the housing.
