Abstract
A method for minimizing thermal expansion in a component (eg, a bearing component) used in a vehicle is provided. The assembly has at least two components having substantially different coefficients of linear thermal expansion (CLTE). The assembly has a first polymer composite with a CLTE, a lightweight metal component (eg, a housing) with a second CLTE, and a third component (eg, a bearing component) with a third CLTE. The second CLTE exceeds the third CLTE by > 25%. The first CLTE is less than or equal to the third CLTE such that the polymer composite structure coupled to the first surface reduces radial thermal expansion of the first metal component and minimizes separation of the second surface of the first metal component from the second component .
Description
technical field [0001] The present disclosure relates to minimizing differential thermal expansion of lightweight metal components by utilizing the strategic incorporation of polymer composites, for example, by incorporating polymer composites into automotive bearing assemblies having lightweight metal components. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Weight reduction for fuel economy in vehicles has motivated the use of various lightweight metal components, such as aluminum and magnesium. While the use of such lightweight metals serves to reduce overall weight and generally improve fuel efficiency, these metals also have a relatively high coefficient of linear thermal expansion compared to traditional steel or ceramic materials. In component assemblies, the use of such lightweight metals can result in non-uniform thermal volumetric expansion under certain the...
