摘要： A gas spring and gas damper assembly includes a gas spring and a gas damper. The gas spring includes a flexible spring member with opposing end members secured thereto and at least partially defining a spring chamber. The gas damper includes an inner sleeve that is at least partially received within one of the end members and at least partially forms a damping chamber. A damper piston assembly is received within the damping chamber and secured to the other of the end members. An elongated damping passage fluidically connects the damping chamber and the spring chamber. Suspension systems and methods are also included.

摘要： A guiding and sealing unit for a shock absorber rod, including a bushing and a sealing assembly including a sealing ring made of an elastomeric material and having at least one annular lip that projects radially and axially towards an axis of symmetry (A) of the unit, and an annular shield that supports and is integral with the sealing ring is provided. The annular shield is formed by a metallic sleeve having a first axial end portion that integrally supports the sealing ring, and from which the annular lip extends in a cantilever fashion inside the metallic sleeve, and a second end portion that integrally houses the annular bushing inside itself.

摘要： A rotary damper includes a housing having an outer cylinder, an inner cylinder coaxially disposed inside the outer cylinder, and a bottom plate closing one end side of the outer cylinder and the inner cylinder, to form an annular liquid chamber with a viscous fluid therein, and a rotor including a cylindrical blade portion rotatably received in the liquid chamber. An annular locking groove extends circumferentially in a first portion at an outer peripheral surface of the inner cylinder, or a second portion facing the first portion on an inner peripheral surface of the blade portion. A locking convex portion projects from the other of the first portion or the second portion, and locked in the locking groove. An annular inside seal member is interposed between the inner cylinder and the blade portion, and an annular outside seal member is interposed between the outer cylinder and the blade portion.

摘要： A fluid damper assembly including a housing that defines a chamber. A rod extends into the chamber and is axially moveable relative to the housing. A bushing is disposed about the rod and is fixed relative to the housing for guiding the rod during the axial movement of the rod. A piston is connected to the rod and is disposed in axially sliding engagement with the housing in the chamber in a compression stroke and in a rebound stroke in response to relative movement between the rod and the housing. A cushioning device extends from the bushing and biases the piston toward the compression stroke for dampening movement of the piston during the rebound stroke of the piston. The cushioning device and the bushing are integral with one another and of a homogeneous material.

摘要： A closing assembly for a magneto-rheological damper includes a housing defining a through bore with a first, second, third, fourth, fifth and sixth counter-bores having varied diameters. A wiper seal is disposed in the first counter-bore and an upper seal is disposed in the second counter-bore. A guide is disposed in the fourth counter-bore. The guide and the upper seal and the third counter-bore define a first chamber. A plate defining a passage is disposed axially below the guide in the fifth counter-bore with a flange extending into the sixth counter-bore. A lower seal is disposed in the passage. The guide and the plate and the fifth counter-bore define a second chamber. The first and second chambers separate and contain a lubricating oil adjacent to the upper seal and lower seal.

摘要： A retrofittable, or originally manufactured, shock piston and cylinder protection seal and method of retrofitting to same is disclosed. A preferred embodiment includes one to four individual wipers contacting the shock piston thereby maintaining its surface free from debris with minimal friction affecting the intended dampening properties of suspension. Different embodiments are further disclosed that allow for loosening of components by threaded members and replacement with either a collar or a foam seal that can peel away from the cylinder for removal and replacement. The originally manufactured version of the invention incorporates the seal housing to a bottom shock cylinder.
