The present disclosure relates to a compression limiter for a composite cover that includes internal threads for receiving a jack screw to assist in removing the cover.
This section provides background information related to the present disclosure which is not necessarily prior art.
Current composite pan/cover assemblies 110 have metallic compression limiters 112 at each bolt hole 114 for receiving a mounting bolt 116, as shown in
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
A cover member includes a body member made of a composite material and including a mounting flange. A plurality of compression limiters are disposed in the mounting flange, the compression limiters have a predetermined thickness and an internally threaded aperture therein. The dual function compression limiters eliminate the need for separate threaded inserts. With the present disclosure, every bolt location provides a potential location for a jack screw.
Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary 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 illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
Corresponding reference numerals indicate corresponding parts throughout the several views of the drawings.
Example embodiments will now be described more fully with reference to the accompanying drawings.
Example embodiments are provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail.
The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
With reference to
The compression limiter 20 as shown in
As shown in
The dual purpose threaded compression limiter 20 combines multiple functions into one component to be used in composite oil pan and cover assemblies. The compression limiter 20 improves serviceability of parts by allowing multiple pry points and reduces cost by eliminating separate threaded inserts. The compression limiters 20 improve component packaging around the sealing perimeter and of the boss around the engine structure. Although the dual purpose compression limiters 20 of the present disclosure have been disclosed in association with an engine assembly 10, it should be understood that the compression limiters 20 can be utilized on various oil pans and covers in engines, transmissions and other industrial machinery in which a composite material is utilized.
The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
