    • A method of making a torsional damper for a motor vehicle intermediate steering shaft including the steps of forming a tubular end on a shaft of the intermediate steering shaft, forming a damper chamber in a yoke of a torsionally rigid universal coupling around and oversize relative to the tubular end of the shaft so that an uncalibrated annular clearance is defined therebetween, disposing a tubular torsion block in the uncalibrated annular clearance with an outside surface bonded to an inside surface of the damper chamber and an inside surface bonded to an outside surface of the tubular end of the shaft, and converting the uncalibrated annular chamber to a calibrated annular chamber by expanding the tubular end of the shaft inside of the damper chamber to radially compress tubular torsion block and increase the torsional stiffness thereof. In a preferred embodiment of the method according to this invention, the tubular torsion block is formed-in-place by injecting a flowable melt of an elastomeric material into the uncalibrated annular clearance which cures solid and is self-bonding to the inside surface of the damper chamber and to the outside surface of the tubular end of the shaft.
    • 一种制造用于机动车辆中间转向轴的扭转阻尼器的方法,包括以下步骤:在中间转向轴的轴上形成管状端,在扭转刚性通用联轴节的轭中形成减振室,并相对于 所述轴的管状端部之间限定了未校准的环形间隙,将管状扭转块设置在未校准的环形间隙中,其外表面与所述阻尼室的内表面接合,并且内表面接合到所述管状体的外表面 并且通过将阻尼室内部的轴的管状端部扩大以径向压缩管状扭转块并增加其扭转刚度,将未校准的环形室转换成校准的环形室。 在根据本发明的方法的优选实施例中,管状扭转块通过将弹性体材料的可流动熔体注入到未固化的环形间隙中而形成就位,其固化固体并且自粘结到 阻尼室和轴的管状端的外表面。
