Power steering system casing with cover fastening mechanism
The patent US12043323B2 describes an innovative assembly designed for use in the power steering systems of motor vehicles. The assembly consists of a cover and a casing that features at least one fastening seat with an orifice. The cover is engineered to seal this orifice, with the fastening seat providing a support wall for the cover. Notably, the fastening seat includes elongation portions that extend outside the support wall, equipped with deformation areas that can be folded over the cover. Additionally, the cover is designed with a groove around its outer periphery to accommodate an O-ring, ensuring a secure seal between the cover and the inner surface of the fastening seat.
The patent further elaborates on the structural details of the assembly, indicating that the inner surface of the fastening seat is configured to delimit the orifice, with the support wall extending transversely. The elongation portions can either be a single continuous piece or consist of multiple deformation areas evenly distributed along the elongation portion. The patent also outlines a method for fastening the cover to the casing, which involves inserting the cover into the orifice and deforming the elongation areas over the holding edge of the cover. This deformation can be achieved through mechanical folding methods, applying pressure either parallel or transverse to the support wall, thereby enhancing the assembly's integrity and functionality in automotive applications.
