Abstract: Methods and associated system for calibrating a torque device are provided. The method includes (I) providing a master torque tool having an accepted calibration, (II) attaching the torque device to be calibrated to an input shaft of a testing and calibration system, (III) energizing the torque device to a free spin under a no load and zero torque condition, (IV) performing a run down test by activating a torque engagement mechanism to transferred torque from the torque device to the master torque tool, (V) measuring a torque value from the master torque tool, the torque device, and the rotary inline torque transducer to generate a data set, (IX) repeating steps (IV) to generate a plurality of data sets and (V), and (VI) generating new calibration factors for input into a programmable control system of the torque device based on the plurality of data sets with a software package.

Abstract: A hydraulic engine mount includes an orifice track formed in a partition between an elastomer body and a base member of the mount, the partition being formed by two separable orifice plates. An annular fluid filled tuning chamber is disposed adjacent the orifice track and separated therefrom by a flexible membrane. An actuator is in communication with the tuning chamber for forcing pressure fluid into or out of the chamber to selectively deflect or distend the membrane to modify the cross sectional area of the orifice track and the vibration damping characteristics of the mount.

Abstract: Hydraulic mounts which include a body member, a partition, a diaphragm and a base member are placed on an apparatus for supporting the body member loosely assembled with the partition, diaphragm and base member. A head member engages the body member and the base member in temporary fluid sealing relationship while air is evacuated from internal chambers of the mount and hydraulic fluid is flowed into the chambers. The head member may then be moved away from the base member and a final assembly of the mount provided by crimping a peripheral upper edge of the body member in forcible engagement with the base member, the partition and the diaphragm. The mount may include spaced apart projections to allow fluid to flow between the partition and the body member during the air evacuation and fluid fill process.
