Abstract: A detent assembly and a method of assembling the detent assembly are disclosed. The detent assembly includes a first shaft rotatable about a longitudinal axis and has an outer surface. The first shaft defines a cavity having an opening defined by the outer surface. The detent assembly further includes a camshaft defining an aperture along the longitudinal axis to present an inner wall of the camshaft that circumscribes the longitudinal axis. The inner wall defines a plurality of recesses spaced from each other. The detent assembly also includes a self-contained plunger unit that is secured to the first shaft in the cavity as a unit. A plunger of the self-contained plunger unit engages the inner wall as the camshaft is disposed over the self-contained plunger unit so that the plunger rests in one of the recesses of the camshaft to selectively secure together the first shaft and the camshaft.

Abstract translation: 公开了一种制动组件和组装定位组件的方法。 制动组件包括可围绕纵向轴线旋转并具有外表面的第一轴。 第一轴限定具有由外表面限定的开口的空腔。 制动组件还包括凸轮轴，该凸轮轴沿着纵向轴线限定孔，以呈现限定纵向轴线的凸轮轴的内壁。 内壁限定彼此间隔开的多个凹部。 制动组件还包括一个独立的柱塞单元，其固定在空腔中的第一轴作为一个单元。 当凸轮轴设置在独立的柱塞单元上方时，独立柱塞单元的柱塞接合内壁，使得柱塞搁置在凸轮轴的凹部之一中，以选择性地将第一轴和凸轮轴固定在一起。
