    摘要: A torque transmission device includes a first shaft is coaxially borne relative to a second shaft via at least one roller bearing. An adjusting device adjusts the amount of torque transmitted from the first shaft to the second shaft by changing the internal bearing friction experienced by the at least one roller bearing. In one embodiment, the adjusting device causes one ring of the at least one roller bearing to axially displace relative to a second ring of the at least one roller bearing, thereby changing the amount of bearing friction experienced by roller bodies disposed between the first and second rings and thus the amount of torque transmitted from the first shaft to the second shaft.

In some aspects, the torque converter further comprises a pump clutch and the method applies torque to the pump clutch and controllably slips the pump clutch. In some aspects, the method supplies engine torque from an engine with a turbocharger and controllably slips the pump clutch to increase speed and torque for the engine during a launch event for the vehicle or determines a parameter regarding operation of the vehicle and controllably slips the pump clutch responsive to the parameter. The present invention also comprises a method for controlling torque converter output by connecting a clutch between an engine and a torque converter and controllably slipping the clutch.

    摘要: The present invention provides a clutch connection method which controls the disconnection/connection of a wet friction clutch on the basis of a duty pulse outputted from an electronic control unit. When the clutch is connected, the electronic control unit initially outputs a start duty (Dst) for largely connecting the clutch as far as the vicinity of a torque point, and, thereafter, outputs, at prescribed time intervals (nullt), a gradual connection duty (Dk) for gradually connecting the clutch, and determines a gradual connection duty value on the basis of a clutch input/output side revolution difference nullN. Since the clutch is gradually connected while monitoring the clutch connection state, variations between connection times and connection shock, resulting from individual clutch differences or the like, can be eliminated, whereby it is possible to achieve a stable feel. Further, in control which connects the clutch in sync with completion of a transmission gear shift, a plurality of clutch connection modes (an engine plus mode, an in-shaft plus mode, and a synchro mode) are preset, and the clutch connection modes are selected in accordance with the size of clutch input-side and output-side revolution numbers upon completion of a gear shift. Clutch connection is performed which conforms to actual conditions since a clutch connection mode is selected in accordance with the size of clutch input/output side revolution numbers rather than with respect to a shift-up or a shift-down.

    摘要: The present invention provides a servo actuated operating mechanism for a coacting lobed rotor positive displacement supercharger combining a low cost and capacity electromagnetic clutch with a small oil pump internal to the supercharger unit. The oil pump supplies on demand oil pressure from oil in a hydraulic clutch housing or the supercharger timing gear case and acts as a servomechanism to actuate an internal hydraulic clutch. The hydraulic clutch can be engaged over a much wider range of speeds and loads than is possible with an electromagnetic clutch alone. The electro-hydraulic servomechanism provides improved highway fuel economy relative to an electromagnetic clutch as the engagement speed could be moved to a higher rotational speed (rpm). The internal hydraulic system makes higher supercharger engagement speeds possible with a hydraulic system, but without the assembly and leak issues associated with externally plumbed engine oil system actuated clutches.
