Abstract
The utility model discloses a lubrication system for front axle steering. The upper section of a master pin is provided with an upper axial center oil hole and an upper radial oil hole communicated with the upper axial center oil hole, and the outer circumferential surface of the upper section of the master pin is provided with an upper oil groove communicated with the upper radial oil hole; the lower section of the master pin is provided with an axial center screw hole and a lower axial center oil hole communicated with the axial center screw hole, the lower section of the master pin is further provided with a lower radial oil hole communicated with the lower axial center oil hole, the outer circumferential surface of the lower section of the master pin is provided with a lower oil groove communicated with the lower radial oil hole, and the lower oil groove is respectively opposite to a thrust bearing and a bushing externally sleeving the lower portion of the master pin. The lubrication system for front axle steering has the advantages that lubricating oil is enabled to directly enter the upper and lower axial center oil holes from oil nipples through a high-pressure oil gun and then extruded out from the upper and lower oil grooves under the pressure of the high-pressure oil gun, and consequently lubrication between the whole master pin and each bushing and each thrust bearing can be guaranteed to slow down abrasion of the master pin.
