摘要： A load sensor assembly for measuring an amount of torque transmitted through a torque establishing element includes a core mounted on a transmission housing and a load sensor mounted on the core. The load sensor is positioned against a portion of the torque establishing element whereby a portion of the amount of torque transmitted through the torque establishing element travels through the load sensor and is measured. A cable is connected to the load sensor for transmitting a signal representative of the amount of torque to a transmission controller.

摘要： According to one or more embodiments, a clutch pack includes a first set of clutch plates arranged in an alternating configuration with a second set of clutch plates. The first set of clutch plates has a plurality of friction pads made of friction material and defining channels in the friction material. The channels are configured to allow lubricant to flow between the friction pads. Each of the friction pads defines a groove in the friction pad. The groove is disconnected from the channels. The groove thereby creates a flow induced high pressure region forcing the first set of clutch plates to a center between the second set of clutch plates.

摘要： A vehicle transmission includes a first rotating element, second rotating element, first retainer ring, and second retainer ring. The first rotating element has an exterior surface that defines a first ring groove. The second rotating element is configured to limit movement of friction plates during clutch engagement. The second rotating element is disposed about the exterior surface and has an interior surface that defines a second ring groove. The first retainer ring is disposed in the first ring groove. The second retainer ring is disposed in the second ring groove and thereby restricts movement of the first retainer ring in a radially outward direction.

摘要： A bench test calibration method for generating wet clutch torque transfer functions includes obtaining in-vehicle clutch torques at a set of shift conditions; performing a series of bench tests at various clutch pack clearances and lubrication oil flow rates at the set of shift conditions; adjusting clutch pack clearances and lubrication oil flow rates during the series of bench tests in response to a difference between a bench test measured clutch torques and the corresponding in-vehicle clutch torques exceeding a threshold; and recording relationships between first bench test measured torques and force profiles of a clutch actuator relative to the adjusted clutch pack clearances and lubrication oil flow rates for each of the set of shift conditions as a first transfer function.
