Abstract: Methods and systems are provided for an actuation system for a driveline shifting member in a transmission system of a vehicle. In one example, a system may include an actuator coupled to a lever arm via one or more parallel axis gears, and a shaft connecting the lever arm to a driveline shifting member, the lever arm driven via a rolling element housed within a slot in the lever arm aligned with a center of a parallel axis gear of the one or more parallel axis gears.

Abstract: The present invention relates, inter alia, to a method for regulating the engagement position of a position-controlled clutch unit for a drive train of a motor vehicle. The clutch unit has at least one wet-running friction clutch for the controllable transmission of a torque from an input element to an output element and an actuator for setting the engagement position for the purposes of mutual compression of the input and output elements. The method compensates a time-dependent setting behavior of the friction clutch on the basis of the uptake of lubrication oil of the friction clutch, which varies over time, in that the engagement position of the clutch unit is regulated by means of the actuator as a function of the time-dependent setting behavior.

Abstract: The present disclosure provides a control method for a vehicle with a DCT, the method including: a diagnosing step of disengaging a corresponding clutch and limiting engine torque to suppress an increase in engine RPM when a controller detects an error from a hall sensor signal, and then applying a test pulse for diagnosing the hall sensor; a reset attempting step of attempting to reset the clutch to an initial position when the controller determines that the hall sensor signal is normal after the diagnosing step; and a returning step of starting normal control of the clutch from the initial position to a target clutch stroke by means of the controller and of removing the limiting of the engine torque, when the clutch is reset to the initial position in the reset attempting step.

The system may have a caster with a body portion, a wheel supported for rolling movement relative to the body portion, and a neck portion. The neck portion may be adapted to be operably coupled to the furniture component to enable swiveling movement of the body portion. A processor may be provided which is supported on the caster. A sensing component may also be included which is carried on the caster for sensing a condition affecting the caster, and generating an output signal in accordance with the sensed condition to the processor.

Abstract: A method of determining automatic transmission lubrication fluid flow rates corresponding to a running vehicle without direct oil flow measurements is disclosed. A set of in-vehicle clutch torques for a chosen clutch pack during a gear shift event for a set of shift conditions is obtained. A series of bench tests at various clutch-pack clearances and oil-flow rates for the set of shift conditions are performed. The clearances and oil-flow rates are adjusted in response to the measured magnitudes exceeding thresholds. In-vehicle transmission lubrication oil-flow rates are estimated at the chosen clutch pack for the set of shift conditions when the bench-test and in-vehicle clutch torques are less than the thresholds. The steps are reproduced for other engine conditions and fluid temperatures corresponding to other transmission gear positions. A functional map of in-vehicle oil flow rates are produced, and the transmission is adjusted based on the map.

Abstract: An alarm device for a clutch that issues an alarm indicating a lifetime expiration of the clutch that selectively connects and disconnects an input shaft to and from an output shaft, includes: a slip heat release threshold setting unit 104 that establishes a threshold criteria as to a clutch damage or the clutch lifetime, in a form of a relation between a heat release generated in a clutch slip operation and a frequency of the heat release occurrences; and a slip heat release calculator 105 that calculates the heat release during the clutch operation, based on a hydraulic oil pressure in an actual clutch operation and a relative circumferential speed between input and output shafts, the alarm device 11 issues the alarm based on the calculation result through the slip heat release calculating means 105 and the slip heat release threshold setting means 104.

Abstract: An automated system for testing a variety of transmissions and drive line gearbox components, and more particularly helicopter transmissions, for reliability, life expectancy, efficiency, and the like on a semi-automated basis. The system powers a unit under test with a pair of AC, variable speed drive motors connected to the transmission through relatively low speed gearboxes which in turn drive the input(s) of the test unit through geared cartridge spindles (GCSs) employing planetary gearset inputs driving a higher speed machine tool type spindle with an output chuck system which can automatically couple to adapters preloaded on the unit under test. Similar GCSs couple the outputs of the test unit to AC motors which act as generators to power the driving motors and thereby reduce the required electric power input to the losses in the system.

Abstract: In a method for checking the auto-opening function of an actuator-operated clutch, the clutch is moved out of its closed position into its open position or out of its open position into its closed position by the actuator at a predetermined constant speed. During this movement of the clutch a force/distance curve is recorded; the point of the path at which the force is minimal is determined; and the clutch is moved to the determined path point by the actuator. The actuator is deactivated; and it is checked whether following deactivation of the actuator, the clutch returns into its open position in a predetermined manner.
