The present disclosure relates to a wedge seal gasket. More particularly, the present disclosure relates to a gasket that forms a wedge seal between two transmission components to seal high pressure hydraulic fluid.
The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art.
In many transmissions, an O-ring is usually positioned between two mating components to form a seal. Such seals, however, are sensitive to surface finish and clamp load. Accordingly, there is a need for a gasket with improved sealing capabilities.
A wedge seal gasket comprising, a carrier, a first wedge seal mounted around the carrier and a second wedge seal mounted around the carrier. The first wedge seal forms a seal with a first housing and the second wedge seal forms a seal with a second housing.
Further features, advantages, and areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustration purposes only and are not intended to limit the scope of the present disclosure in any way. The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Moreover, in the figures, like reference numerals designate corresponding parts throughout the views. In the drawings:
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.
Referring now to the drawings, a wedge seal gasket embodying the principles of the present invention is illustrated in
As shown in
In certain arrangements, the wedge seal gasket 10 includes one or more additional seal beads positioned between the carrier 12 and the wedge seals 14 and 16. For example, a pair of spaced apart seal beads 26 and 28 are mounted concentrically around the carrier 12 (or the first member 12a) between the carrier 12 (or the first member 12a) and the first wedge seal 14 to enhance the seal between the carrier 12 (or the first member 12a) and the first wedge seal 14. A second pair of spaced apart seal beads 30 and 32 can be mounted concentrically around the carrier 12 (or the second member 12b) between the carrier 12 (or the second member 12b) and the second wedge seal 16 to enhance the seal between the carrier 12 (or the second member 12b) and the second wedge seal 16.
The seal beads 18, 20, 22, 24, 26, 28, 30 and 32 can be made from rubber, silicone or any other suitable material.
As further shown in
When the wedge seal gasket 10 is in use, high pressure hydraulic fluid flows through the port 46 of the housing 42 to the wedge seal gasket 10 and exits the wedge seal gasket 10 into the port 44 of the mating housing 40 as indicated by the arrows 50. In the meanwhile, the wedge seal gasket 10 provides an axial seal (as indicated by arrows 52) and a seal with radial and axial components (as indicated by arrows 54) between the wedge seal gasket 10 and the housing 42 and the mating housing 40.
In a particular arrangement, the housing 42 is a clutch housing, the mating housing 40 is a concentric slave cylinder (CSC) housing, and the wedge seal gasket is a CSC gasket.
The description of the invention is merely exemplary in nature and variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
