    • A suspension apparatus for use in a vehicle including a body, a body-side member (16), a wheel (12), and a wheel-side member (14), the apparatus comprising a hydraulic suspension device (10) which is provided between the body-side member and the wheel-side member; a first liquid passage (60, 62); a first connection portion (68); a first accumulator (42) which is connected to the first liquid passage via the first connection portion and is connected to the hydraulic suspension device via the first connection portion and the first liquid passage; a second liquid passage (64); a second connection portion (67); a second accumulator (44) which is connected to the second liquid passage via the second connection portion and is connected to the first liquid passage via the second connection portion and the second liquid passage; and a liquid-flow control device (70) which controls a flow of a hydraulic liquid between the hydraulic suspension device and at least one of the first and second accumulators. In a state in which the liquid-flow control device allows the hydraulic liquid to flow from the hydraulic suspension device into each of the first and second accumulators, the first liquid passage and the first connection portion allow the hydraulic liquid to more easily flow therethrough into the first accumulator than the second liquid passage and the second connection portion allow the hydraulic liquid to flow therethrough into the second accumulator.

    • A vehicle suspension assembly (20) includes a shock absorber (30) that provides variable damping dependent on the load conditions of the vehicle. A central rod (50) of the shock absorber includes a central bore (82) that is fluidly coupled with air pressure within air springs (22,24) of the suspension assembly. As the vehicle load increases and the pressure within the air springs increases, a damping adjustment assembly within the shock absorber increases the stiffness or damping of the shock absorber. In one example, a plunger (84) moves within the central bore in the rod between a first position where less damping is provided and a second position where increased damping is achieved. A unique adapter member (100) facilitates using a rod of appropriate size to achieve the desired air pressure conditions within the rod, while at the same time supporting conventional piston and disc valve components and providing enough material strength to withstand the tensile loads experienced under full extension. The adapter also includes a check valve to control fluid flow and provides a hydraulic cushion feature.
    • 车辆悬架组件(20)包括减震器(30),其根据车辆的负载状况提供可变阻尼。 减震器的中心杆(50)包括与悬架组件的空气弹簧(22,24)内的空气压力流体连接的中心孔(82)。 随着车辆载荷增加并且空气弹簧内的压力增加,减震器内的阻尼调节组件增加了减震器的刚度或阻尼。 在一个示例中,柱塞(84)在杆的中心孔内在提供较少阻尼的第一位置和实现增加阻尼的第二位置之间移动。 独特的适配器构件(100)便于使用适当尺寸的杆来实现杆内所需的空气压力条件,同时支撑常规的活塞和盘形阀组件并提供足够的材料强度以承受满载下经受的拉伸载荷 延期。 适配器还包括一个单向阀,用于控制流体流动并提供液压缓冲功能。
