    • A rack seal for use with a rack bushing and seal retainer wherein the rack bushing is made of a thermoplastic material and includes a face with a plurality of cooling cavities. The rack seal includes a body member, an annular sealing face, and a retainer air side which is in constant contact with the thermoplastic bushing cavity face. The rack seal air side surface includes a bead segment. The bead segment has a predetermined height which creates a minimum contact at a full gap with the rack bushing and is compressible to a minimum gap with the rack bushing. The bead segment of the rack seal is in constant contact with the thermoplastic bushing such that any objectionable noises are eliminated during any separation of the rack seal and the thermoplastic bushing.
    • 用于齿条衬套和密封保持器的齿条密封件,其中齿条衬套由热塑性材料制成并且包括具有多个冷却腔的面。 齿条密封件包括本体构件,环形密封面和与热塑性衬套腔面恒定接触的保持器空气侧。 齿条密封空气侧面包括胎圈段。 胎圈段具有预定的高度,其在与齿条衬套的全部间隙处产生最小接触,并且可压缩至与齿条衬套的最小间隙。 齿条密封件的胎圈段与热塑性衬套保持恒定接触,从而在齿条密封件和热塑性衬套的任何分离期间消除任何令人不快的噪音。
