摘要： A track tension actuator is provided for a track assembly having, an idler wheel, a drive wheel, a drive track entrained about the drive wheel and idler, and a hydraulic motor operable to advance the drive wheel. A drive circuit is operable to supply pressurized fluid to the hydraulic motor. The actuator is coupled to the idler wheel, and includes a travel chamber, travel piston, a recoil chamber, and a recoil piston. The recoil chamber is pressurized to urge the recoil piston in a first direction away from the drive wheel. The drive fluid pressurizes the travel piston, which in turn contacts and urges the travel piston in a second direction against the recoil piston to reduce the track tension.

摘要： A system and method for optimizing machine performance using speed shaping in a machine having an engine and a drivetrain implementing engine underspeed module receives a throttle command requesting an increase in engine speed and transmits the throttle command to the engine. If the requested increase exceeds a predetermined function, the predetermined function is forwarded to the engine underspeed module as a speed standard. The engine underspeed module determines whether the actual engine speed attained by the engine is less than the speed standard by more than a predetermined gap value and, if so, reduces the power required by the drivetrain to avoid lugging of the engine.
