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.

摘要： The present invention relates to a power transmission arrangement (10) for a construction vehicle (1), comprising an engine (4), a hydraulic power system (12, 13) for powering work hydraulics (7, 8) of the construction vehicle (1), which is feedable with power from the engine (4), the hydraulic power system (12, 13) including a power limiter (17) for limiting the power supply of the engine (4) to the hydraulic power system (12, 13) to different power limit values, a drivetrain power system (11) for powering locomotion of the construction vehicle (1), the drivetrain power system (11) being feedable with power from the engine (4), a determining device for determining an operational state of the construction vehicle (1), and a controller (22) configured to control the power limiter (17) to limit the power supply of the engine to the hydraulic power system (12, 13) to different power limit values, these power limit values being set depending on the operational state of the construction vehicle (1) determined by the determining device. Furthermore, the present invention relates to a construction vehicle including such a power transmission arrangement and a method of controlling such a power transmission arrangement.
