摘要： A drive sprocket assembly for driving an endless chain assembly for propelling a machine has a hub portion and flexible cantilever teeth in which each tooth is separately deflectable upon impact by a bushing of the endless chain assembly. The flexibility of each tooth will absorb a portion of the kinetic energy of the impact to reduce noise in the structure. The drive sprocket assembly includes a plurality of segments each having the cantilever teeth. Each segment has a first end portion and a second end portion having an end relief which prevents wear between the segment and the hub as the end portion is deflected by the impact.

摘要： A system and method for controlling a hydraulic transmission uses a clutch fill profile having a hold level that varies as a function of torque. A pressure required for an on-coming clutch to hold the gear of the off-going clutch without a flare or over-speed condition is calculated. This pressure approximates the pressure of the on-coming clutch when a disengage command with respect to the off-going clutch is reached. The pulse and hold phases for the clutch are executed at times that are constant from shift to shift and do not vary as a function of torque or slip.

摘要： A calibration system for calibrating a transmission adjusts a clutch fill pulse width and hold level current for an oncoming clutch via calibration shifts during operation of the associated machine, thus establishing the desired shift timing and duration. The pulse width is calibrated based on torque transfer characteristics of the clutch during a test shift, and the hold level current is calibrated based on the shift duration of a further test shift.
