摘要： A method of adjusting the length of a vehicle brake booster output rod and assembling the same into the brake booster is provided, the output rod being a thermoplastic or thermoset material that is generally cylindrical in shape with a central longitudinal bore with an axial stop means, and the output rod having an insertable button having a head with an attached stem, the booster having a housing with a central opening surrounding the output rod with a surrounding first formed surface for mounting a master cylinder, the method including piloting a cutting tool by inserting an elongated member into the bore of the output rod, orienting the cutting tool by mating a fixture locationally associated with the cutting tool on the first formed surface of the vacuum booster housing, preloading the output rod with the elongated rod by contacting means with the elongated rod to simulate a spring load of a master cylinder, cutting the output rod with the cutting tool to the correct dimension, removing the elongated member from the output rod bore, and inserting the stem of the button into the output rod with a sheet material juxtaposed between the stem and the bore of the output rod causing an interference fit retaining the button into the output rod bore.

摘要翻译： 提供了一种调节车辆制动助力器输出杆的长度并将其组装到制动助力器中的方法，输出杆是热塑性或热固性材料，其通常为圆柱形，中心纵向孔具有轴向止动装置， 并且所述输出杆具有可插入按钮，所述可插入按钮具有带有附接杆的头部，所述助推器具有壳体，所述壳体具有围绕所述输出杆的中心开口，所述中心开口具有围绕的用于安装主缸的第一成形表面，所述方法包括通过插入切割工具 将细长构件插入输出杆的孔中，通过将位于与切割工具相关联的夹具与位于真空助力器壳体的第一成形表面上的夹具对准来定向切割工具，通过接触装置将细长杆预先加载到细长杆上， 杆模拟主缸的弹簧载荷，用切削工具将输出杆切割成正确的尺寸， 从输出杆孔中切割细长构件，以及将按钮的杆插入输出杆中，并将片材并排在杆和输出杆的孔之间，从而将按钮保持在输出杆孔中。
