    • The apparatus includes a bellows (1), a first protection sleeve element (8) having a substantially radially upturned annular end portion (13) and a second protection sleeve element (6) having also a substantially radially upturned end portion (17). The bellows (1) ends at both sides in a neck (2, 3). A cylindrically shaped portion (12) of the first protection sleeve element (8) is surrounded by an envelope part (9) having a cylindrically shaped portion (10) and a substantially radially upturned annular end portion (11). Likewise, a cylindrically shaped portion (25) of the second protection sleeve element (6) is surrounded by an envelope part (14) having a cylindrically shaped portion (15) and a substantially radially upturned annular end portion (16). The necks (2, 3) of the bellows (1) are sandwiched between the cylindrically shaped portions (10, 12; 15, 25) of the respective envelope parts (9, 14) and the first protection sleeve element (8) and the second protection sleeve element (6) are welded thereto. The upturned end portions (11, 13; 16, 17) of the respective envelope parts (9, 14) and the first (8) and second protection sleeve elements (6) contact each other and form the flanges (4, 5) of the apparatus.

    • Flexible connector systems are provided for decoupling vibrations between two components of an exhaust system of a vehicle, for example a exhaust manifold and an exhaust down pipe. The flexible connector systems are configured for providing sealed, substantially leak-proof connections which are capable of accommodating axial elongation and contraction, as well as pivoting movements of one component, relative to another component. The flexible connector systems include mating structures which are configured to mate with existing manifold outlet formations, with little or no modification of the exhaust manifold configuration. Ball joint structures and/or resilient mounting materials are used for accommodating pivoting movements. Bellows are provided for accommodating elongation and contraction, while providing sealing enclosure of pipe elements transporting the exhaust gases.
    • 提供柔性连接器系统用于在车辆的排气系统(例如排气歧管和排气管)的两个部件之间去耦合振动。 柔性连接器系统被配置为提供密封的,基本上防漏的连接,其能够容纳轴向伸长和收缩以及相对于另一部件的一个部件的枢转运动。 柔性连接器系统包括配置结构,其配置成与现有的歧管出口结构配合,几乎不改变排气歧管构型。 球接头结构和/或弹性安装材料用于容纳枢转运动。 提供波纹管用于容纳伸长和收缩,同时提供输送废气的管道元件的密封外壳。
