Connection Device for a Transmission Vent

Abstract

A connection device for a ventilation element includes a transmission connection and a vent connection, the vent connection connects the connection device to a ventilation element, the component connection has a connection piece extending along a connecting axis, and a torsion ring surrounding the connection piece. A connecting rocker is arranged on the torsion ring, and the torsion ring is connected to the connection piece by a connecting bridge, and the connecting rocker has an actuation section and an engaging section for forming an interlocking connection. The torsion ring runs between the actuation section and the engaging section in a connecting region, in which it is connected to the connecting rocker, and the connecting bridge has a connecting arm, which starts from the connection piece and extends in the direction of the connecting axis up to the torsion ring and retains same at a radial distance from the connection piece.

Claims

1-6. (canceled)

7. A connection device for a ventilation element comprising: a transmission connection; and a venting connection, wherein the venting connection is configured to connect the connection device to a ventilation element, and wherein a component connection has a connection piece which extends along a connecting axis and the component connection furthermore has a torsion ring which surrounds the connection piece, wherein at least one connecting rocker is arranged on the torsion ring and the torsion ring is furthermore connected to the connection piece by a connecting bridge and the connecting rocker has an actuation section and a latching section for forming a form-fitting connection, wherein the torsion ring, in a connecting region in which said torsion ring is connected to the connecting rocker, extends between the actuation section and the latching section, and wherein the connecting bridge has at least one single connecting arm, which departs from the connection piece and extends in the direction of the connecting axis as far as the torsion ring and holds the latter spaced apart radially from the connection piece.

8. The connection device according to claim 7, wherein the connection device has two connecting rockers, and wherein the two connecting rockers are connected to the torsion ring and are arranged oppositely from the latter on the connection piece.

9. The connection device according to claim 7, wherein the torsion ring is held on the connection piece by two connecting arms by way of a connecting bridge, wherein the connecting arms are arranged oppositely on the connection piece, wherein the connection device has two connecting rockers, and wherein the connecting arms and the connecting rockers are arranged on the connection piece in an alternating manner and in each case so as to be offset by 90° around the connecting axis.

10. The connection device according to claim 7, wherein the connection piece has an outer surface, and wherein at least one seal section is arranged, and formed as a recess, on said outer surface.

11. The connection device according to claim 10, wherein the seal section is in the form of a radially encircling groove.

12. A drive-component venting apparatus comprising: the connection device according to claim 7, wherein the connection piece, at a first axial end, is connected in a fluid-conducting manner to a ventilation component, wherein the at least one connecting rocker is configured to form a form-fitting connection to a media line which is connected to a drive-component interior space, and wherein the media line is connected in a form-fitting manner to a second axial end of the connection piece.

DETAILED DESCRIPTION

[0023] FIG. 1 shows a perspective view of a venting apparatus having a transmission vent and having the described connection device, this consequently forming a transmission venting apparatus having a connector 1 and having a transmission vent 2. The transmission vent 2 is connected to the connector 1. The connector has the torsion ring 7, which is held on the connection piece 1 via the connecting arm 13. The torsion ring 7 is connected in the connecting region 12 to the connecting rocker 8, which has the actuation section 11 and the latching section 9. A connector 1 having two connecting rockers 8 is illustrated. If a sufficiently large actuating force is applied to the actuation section 11, then the latter moves radially inward in the direction 16, while the latching section 9 moves radially outward in the direction 17. During a movement in the direction 17, the latching section is lifted out of a latching recess (not illustrated) and, in this way, the latching connection is released without a tool.

[0024] FIG. 2 shows a sectional illustration of the connection device, wherein the section extends through the two connecting rockers 8, which are thus illustrated in section. It can be seen that the two connecting rockers 8 are arranged oppositely on the connection piece 5 and are connected in the connecting region 12 to the torsion ring 7. The connection piece is substantially in the form of an annularly cylindrical tube and extends along the connecting axis 6 between the vent connection 4 (at the top in the figure) and the transmission connection 3 (at the bottom in the figure).

[0025] FIG. 3 illustrates the same connection device as is illustrated FIG. 2, the section plane being rotated through 90° in this figure however, so that the section extends not through the connecting rockers, as in FIG. 2, but through the two connecting arms 13 of the connecting bridge 10. The connection device is illustrated with the same orientation in relation to the vent connection 4 (at the top) and the transmission connection 3 (at the bottom) as in FIG. 2. The torsion ring 7 is held by the two connecting arms 13 and extends radially at the outside around the connecting axis 6 and the connection piece 5. The seal section 15 is formed as a radially encircling groove in the outer surface 14 of the connection piece for the purpose of receiving a seal element.

[0026] In relation to this illustration, the seal section 15 is formed completely above the latching section 9 in the direction of the connecting axis 6, this being shown in particular in FIG. 2.
