| 摘要 |
The invention concerns a device (1) for protecting a steering mechanism (2) of a vehicle, said device (1) comprising a housing element (5) defining a chamber (7) of which the wall (6) is perforated with at least one access opening (8), and a plastic cap (10) that shuts said access opening (8), said cap (10) having, along the director axis (XX′) thereof, a stepped structure comprising a hub (11), which is engaged in a bore (12) of the access opening (8) and carries a sealing lining (13) that engages with said bore (12), then a collar (14), of which the overall diameter (D14) is greater than the diameter (D12) of the bore (12), said collar (14) being engaged by snap-fitting into a stop groove (20) hollowed into the housing element (5), and forming a baffle deflector (21) of which the diameter (D21) is greater than that (D12) of the bore (12). |

1. A device for protecting a mechanism, such as a steering mechanism of a vehicle, said device comprising,
a casing element which forms a wall delimiting a chamber which is intended to receive and accommodate said mechanism, said wall being pierced with at least one access orifice enabling access to the chamber from an outside of said casing element, and a plug which closes said access orifice, wherein the plug presents an axially stepped structure, which comprises successively, along a main axis of said plug, a hub, which is engaged in a bore of the access orifice, said hub being oriented toward the chamber and carrying a sealing gasket which cooperates with said bore of the access orifice, then a flange, which is oriented toward the outside of the casing element and an overall diameter of which is larger than a diameter of the bore, said flange being, engaged to bear in a stop groove hollowed in the casing element radially offset with respect to the bore, so that said flange opposes, by snap-fitting, the extraction of the plug out of the access orifice, and said flange presenting a solid portion which extends radially from the hub so as to form a deflector, a diameter of which is larger than that of the bore, so that the deflector covers a circumference of said bore by defining a radial baffle which protects the hub and the sealing gasket. |
