International Classification:

F16H 27/02

US Classification:

74 8938

Abstract:

An actuating device for a motor vehicle transmission having multiple transmission steps, having a threaded spindle which is mounted so it is rotationally movable and axially fixed and a spindle nut which is positioned on this threaded spindle and may be driven thereby, and also having a first component, which is positioned so it is axially fixed and rotatable to select gears of the motor vehicle transmission, which may be coupled and/or is coupled via a rotational carrier unit to the spindle nut, so that the first component may be driven to rotate by the threaded spindle via the spindle nut to select gears, a braking unit being provided to reduce and/or avoid axial position changes of the spindle nut caused by mass inertia as a result a braking procedures of the threaded spindle from a movement rotationally driving the first component; as well as a motor vehicle transmission unit, a motor vehicle drivetrain, and a method for reducing or avoiding control errors caused by mass inertia in the control of gear changing actions in a motor vehicle transmission.

Abstract:

A torque converter including a cover having a central longitudinal axis and an outer surface and a pilot stamped from metal. The pilot includes a disc at least partially radially aligned with the axis for the cover. The pilot and the cover central axis are fixedly secured to each other. In a first embodiment, the disc is flat. In a second embodiment, the disc is annular. In a third embodiment, the pilot includes a machined outer circumferential surface. In a fourth embodiment, the pilot includes first and second portions radially off-set with respect to one another. In a fifth embodiment, the pilot includes a portion axially extending from the portion of the disc at least partially radially aligned with the axis for the cover. In a preferred embodiment, the cover and pilot are fixedly secured by welding.

Assignee:

Schaeffler Technologies GmbH & Co. KG - Herzogenaurach

International Classification:

B60W 10/02

US Classification:

477180

Abstract:

The present invention broadly comprises a method for controlling engine speed, engine torque, and torque converter output including the steps of applying engine torque to a torque converter and modulating the transferring of the torque to a pump for the torque converter. 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.

International Classification:

F16H 45/02

US Classification:

192 329, 1922132, 19221322

Abstract:

A series damper, including: a first damper with a flange and a cover plate; and a second damper with first and second cover plates and a flange. The flange and the cover plate for the first damper are rotationally frictionally engaged and the flange for the second damper rotates free of frictional engagement with the first and second cover plates. The series damper includes a resilient element arranged to cause the frictional engagement of the flange and the cover plate for the first damper. In some aspects, the resilient element is frictionally engaged with the cover plate for the first damper and is arranged to frictionally engage a turbine hub for a torque converter. In some aspects, the resilient element is rotationally connected to the flange for the first damper.
