摘要： A lithium-based grease and the preparation method thereof are provided. The raw materials for preparing the lithium-based grease include in parts by weight: 75-88 parts of base oil, 0.5-2.5 parts of antiwear agent, 0.1-1.5 parts of antirust agent, 0.1-1.5 parts of antioxidant, 5-25 parts of lubricant, 5-15 parts of thickening agent, and 0.6-2.0 parts of saponifying agent. The raw materials also include hydroxyl compound-containing modified graphene containing quaternary ammonium salt or aromatic ring. The grease has good colloid stability and mechanical stability, can greatly improve the antiwear property. More than that, the grease has excellent oxidation resistance, and can significantly shorten the reaction time of the saponification, reduce the reaction temperature of the saponification.

摘要： A track wheel suspension for a construction machine is introduced. The track wheel suspension comprises a track wheel engageable to a track and a swing device comprising a first coupling portion. The first coupling portion is arranged for rotatably supporting the track wheel. Furthermore, the track wheel suspension comprises a swing bar with a first bar end which is arranged for being mounted to a second coupling portion of the swing device. The swing bar provides a swing axis which is offset from a rotation axis of the track wheel such that a swing movement of the swing device enables a movement of the track wheel in a direction which is substantially perpendicular to the rotation axis.
