Failsafe air valve arrangement

摘要

An air valve arrangement for a motor vehicle, comprising a frame and an air valve provided on said frame so as to be rotatable thereto about an axis of relative movement (R) in opposing directions of relative rotation, the frame comprising an air passage opening, and the air valve is provided in such a way on the frame that it is rotatable between a shut-off position and a passage position, the air valve in the passage position reducing a passage opening area of the air passage opening less than in the shut-off position, and further comprising a drive, which is designed to drive the air valve in at least one first direction of relative rotation about the axis of relative movement (R) for relative rotation, characterized in that the air valve is coupled to a preloading device, which preloads the air valve in a direction of relative rotation.

主权项

1. An air valve arrangement for a motor vehicle, comprising:
a frame comprising an air passage opening having a passage opening area; an air valve provided on said frame so as to be rotatable thereto about an axis in opposing directions of relative rotation, provided in such a way on the frame that it is rotatable between a shut-off position and a passage position, the air valve in the shut-off position reducing the passage opening area of the air passage opening from in the passage position; and a drive, which is designed to drive the air valve in at least one first direction of the relative rotation about the axis; wherein the air valve is coupled to a preloading device, which preloads the air valve toward the passage position in a direction of relative rotation; wherein the preloading device comprises an at least two-part housing, with a first housing part non-rotatable relative to the frame and with a second housing part non-rotatable relative to the air valve; wherein a preloading means is accommodated in the interior of the housing; wherein the first and the second housing parts are coupled to one another in a torque-transmitting manner via the preloading means.
