    • A pulse vacuum hub lock system for selectively engaging a wheel hub to an axial shaft includes a cartridge housing assembly received in a bore in the wheel hub. The cartridge housing assembly supports a clutch ring for movable engagement between splines in the wheel hub and directly on the axle shaft. A diaphragm is connected to a piston assembly and is responsive to a vacuum pressure to activate the piston assembly to engage or disengage a latch mechanism that holds the clutch ring in an engaged or disengaged position. A piston spring and a helper spring are provided between primary and secondary pistons of the piston assembly and allow for separation in the vacuum levels required to activate the latch mechanism. The vacuum hub lock system is compact so as to be disposed inboard of an opening in the exterior surface of a wheel rim.
    • 用于将轮毂选择性地接合到轴向轴的脉冲真空轮毂锁定系统包括容纳在轮毂中的孔中的盒壳体组件。 盒壳体组件支撑离合器环,用于可动接合轮毂中的花键和直接在车轴上。 隔膜连接到活塞组件,并且响应于真空压力以启动活塞组件以将锁定机构接合或分离,所述闩锁机构将离合器环保持在接合或脱离位置。 活塞弹簧和辅助弹簧设置在活塞组件的主活塞和次活塞之间,并允许在启动闩锁机构所需的真空水平中进行分离。 真空轮毂锁定系统是紧凑的,以便被设置在轮辋的外表面中的开口的内侧。
