US 12,584,526 B2 · Coupling device and drive train for a motor vehicle

Abstract

A coupling device for coupling and decoupling a drive element with an output element of a drive train for a motor vehicle includes a coupling element, linearly displaceable from a coupling position to a decoupling position, a first latching device for fixing the coupling element in a one of the coupling position or the decoupling position, a first spring element for urging the coupling element into the other one of the coupling position or the decoupling position, and a first actuator arranged to cancel the fixing of the first latching device and to further load the first spring element to displace the coupling element into the other one of the coupling position or the decoupling position. In the coupling position, the coupling element couples the drive element with the output element, and, in the decoupling position, the drive element is decoupled from the output element.

Dependent claims

A coupling device for coupling and decoupling a drive element with an output element of a drive train for a motor vehicle, comprising a coupling element which can be transferred from a coupling position, in which it couples the drive element with the output element, into a decoupling position, in which the drive element is decoupled from the output element, and vice versa,

wherein at least one actuator, at least one latching device and at least one spring element are provided, wherein the coupling element is fixed in the coupling or decoupling position as a starting position by means of the latching device while the spring element is simultaneously under load and loads the coupling element into the respective other position, and wherein the spring element can be further loaded by means of the actuator for transfer into the respective other position and the fixing by the latching device can be canceled such that the coupling element can be linearly displaced into the other position by means of the spring element after release by the actuator,
wherein the spring element is arranged between the coupling element and a component that is stationary with respect to a housing of the coupling device, or an inner housing arranged in the housing, and is supported thereon.

A coupling device for coupling and decoupling a drive element with an output element of a drive train for a motor vehicle, comprising:

a coupling element, linearly displaceable from a coupling position to a decoupling position;
a first latching device for fixing the coupling element in a one of the coupling position or the decoupling position;
a first spring element for urging the coupling element into the other one of the coupling position or the decoupling position;
a first actuator arranged to cancel the fixing of the first latching device and to further load the first spring element to displace the coupling element into the other one of the coupling position or the decoupling position;
and
a housing, the first spring element being arranged between:
the coupling element and the housing;
or
the coupling element and an inner housing arranged in and supported on the housing, wherein:
in the coupling position, the coupling element couples the drive element with the output element;
and
in the decoupling position, the drive element is decoupled from the output element.
