Abstract
A metering device for controlling an oil delivery rate for a wet-running clutch. The wet-running clutch has at least one pair of interacting friction surfaces and an actuation unit for actuating the wet-running clutch. The actuation unit has an axially supported support disk and an axially displaceable thrust disk, wherein the thrust disk and the support disk are rotatable relative to one another. The metering device has a first component which is connected fixedly with respect to a housing, and a second component which is connected to the thrust disk in a rotationally conjoint and axially relatively displaceable manner.
Claims14
A metering device for use with a wet-running clutch having an actuation unit with an axially supported support disk and a thrust disk axially displaceable relative to the support disk as a result of rotation of the thrust disk relative to the support disk, the metering device operable to control an oil delivery rate to the wet-running clutch and comprising a first component which is connected fixedly with respect to a housing, and a second component which is connected to the thrust disk in a rotationally conjoint and axially relatively displaceable manner, wherein the first component is fluidically connected to an oil reservoir having a geodetic height relative to the first component;
- wherein the oil reservoir is arranged at a chain, and wherein the chain conveys the oil into the oil reservoir;
- wherein an inner wall of a transfer gear cover forms a delimitation of the oil reservoir;
- and
- wherein the transfer gear cover has a scraper lip, wherein the scraper lip scrapes off the oil that is conveyed along by the chain, and conducts the oil into the oil reservoir.
A metering device for use with a wet-running clutch having an actuation unit with an axially supported support disk and a thrust disk axially displaceable relative to the support disk as a result of rotation of the thrust disk relative to the support disk, the metering device operable to control an oil delivery rate to the wet-running clutch and comprising a first component which is connected fixedly with respect to a housing, and a second component which is connected to the thrust disk in a rotationally conjoint and axially relatively displaceable manner, wherein the first component is fluidically connected to an oil reservoir having a geodetic height relative to the first component;
- wherein the second component is connected to the first component by being plugged onto the latter.
A metering device for use with a wet-running clutch having an actuation unit with an axially supported support disk and a thrust disk axially displaceable relative to the support disk as a result of rotation of the thrust disk relative to the support disk, the metering device operable to control an oil delivery rate to the wet-running clutch and comprising a first component which is connected fixedly with respect to a housing, and a second component which is connected to the thrust disk in a rotationally conjoint and axially relatively displaceable manner, wherein the first component is fluidically connected to an oil reservoir having a geodetic height relative to the first component;
- wherein the second component has a rib, and wherein the rib permits an axial displacement of the thrust disk relative to the second component.
A metering device for use with a wet-running clutch having an actuation unit with an axially supported support disk and a thrust disk axially displaceable relative to the support disk as a result of rotation of the thrust disk relative to the support disk, the metering device operable to control an oil delivery rate to the wet-running clutch and comprising a first component which is connected fixedly with respect to a housing, and a second component which is connected to the thrust disk in a rotationally conjoint and axially relatively displaceable manner, wherein the first component is fluidically connected to an oil reservoir having a geodetic height relative to the first component;
- wherein the second component has at least one lubrication bore on a circumferential surface.
