Patent
Mahle GmbH and Mahle Engine Systems UK Ltd | Date: 2016-08-18

A sliding element, e.g., a sliding element for slidably supporting a rotatable shaft, may include a first sliding element component, a second sliding element component, and at least one coupling element. The at least one coupling element may be configured to be coupled to the first sliding element component and may be configured to be coupled to the second sliding element component to releasably couple the first sliding element component and the second sliding element component together.

A sliding element (20) comprises a first sliding element component (21) for sliding engagement with a rotatable component and a second sliding element component (22,23) for sliding engagement with a rotatable component. The first sliding element component is coupled to the second sliding element component by an adhesive (31). The adhesive is a flexible adhesive. A corresponding method of manufacturing the sliding element (20) comprising the steps of:- providing a first sliding element component (21) for supporting rotatable component; providing a second sliding element component (22,23) for supporting a rotatable component; applying a flexible adhesive (31) to the first sliding element component (21) and/or to the second sliding element component (22,23); bringing the first sliding element and the second sliding element component into engagement to form an assembly; allowing the flexible adhesive (31) to at least partially cure for a handling time so as to form a self-supporting sliding element or a flanged half-bearing or a flanged bush assembly.

A sliding engine component may include a substrate having a surface coated with a first electroplated metallic layer and a second electroplated metallic layer. The first metallic layer may be disposed between the substrate and the second metallic layer. The first metallic layer and the second metallic layer may have a grained structure. The grained structure of each of the first metallic layer and the second metallic layer may have an aspect ratio between a mean grain size perpendicular to the substrate surface and a mean grain size parallel to the substrate surface. The aspect ratio of the second metallic layer may be less than the aspect ratio of the first metallic layer.

A sliding engine component may include a sliding surface including a plastic polymer-based layer disposed on a metallic substrate. The plastics polymer-based layer may include a plurality of plastic polymer-based layers. The plurality of plastic polymer-based layers may include a first coating of a first polymer-based layer deposited on the metallic substrate and cured at a first temperature, and a second coating of a second polymer-based layer deposited onto the first polymer-based layer and cured at a second temperature. The second temperature may be lower than the first temperature.


Patent
Mahle GmbH and Mahle Engine Systems Uk Ltd. | Date: 2014-05-07

A sliding engine component may include a sliding surface including a plastics polymer-based composite layer disposed on a substrate. The composite layer may include a matrix of plastics polymer-based material. The plastics polymer-based material may have 0.1 to 20 percent by volume of liquid-filled microcapsules distributed throughout the matrix, and incidental impurities.
