A shock absorber for damping movement of a wheel suspension system of a vehicle can include a damper tube, a piston, a damping adjustment assembly, and a protective cover. The damper tube can contain a fluid. The piston can be located in the damper tube so as to accommodate relative movement between the damper tube and the piston. The damping adjustment assembly can be connected to the damper tube, and can include a reservoir, a solenoid valve, and a wire harness connection. The solenoid valve can be in fluid communication with each of the reservoir and the damper tube and configured to selectively open and close fluid communication between the reservoir and the damper tube. The wire harness connection can be in electrical communication with the solenoid valve. The protective cover can contain the wire harness connection.

A shock absorber includes: a cylinder which is filled with a fluid; a piston valve which includes a valve seat dividing an inner space of the cylinder, a passage which is formed in the valve seat and through which the fluid passes, and a valve disposed to cover the passage and interfering with a flow of the fluid; a performance controller which is disposed in the cylinder to control at least one of a spring constant, a damping force, or a combination thereof; and a piston support which is connected to the piston valve and exposed to an outside.

A liquid gas supporting shock absorber. An oil path of the liquid gas supporting shock absorber, mainly composed of a liquid gas accumulator (4) and a single-acting hydraulic cylinder (7), is divided into a liquid inlet oil path (9) flowing into the single-acting hydraulic cylinder (7) and a liquid outlet oil path (6) flowing out of the single-acting hydraulic cylinder (7). A supporting force value of the liquid gas supporting shock absorber on an item supported thereby is measured using a force measuring element. A control component (1) compares the supporting force value to a set force value or a gravity value of the item supported by the supporting shock absorber, and the damping of the liquid inlet oil path (9) and the liquid outlet oil path (6) of the liquid gas supporting shock absorber is controlled by means of a mechanical, hydraulic or electronic control mode according to the result of the comparison, so as to adjust the supporting force value of the supporting shock absorber, so that the supporting force value of the supporting shock absorber is equal to or close to the set force value or the gravity value of the item supported by the supporting shock absorber.

A compression damper of a shock absorber includes: a single adjustable fluid circuit configured for controlling a damping rate associated with multiple compression speeds of the shock absorber, wherein the single adjustable fluid circuit includes a fluid passageway through a base valve; and a positionally adjustable floating shim stack positioned at one end of the fluid passageway, the positionally adjustable floating shim stack configured for selectively blocking a flow of fluid through the fluid passageway.

Presented herein, inter alia, are suspension system components having tuned accumulator sizing and/or stiffness. Such suspension system components are envisioned for use in a distributed active suspension system of a vehicle. In particular, through appropriate sizing of accumulators of a suspension system component of a vehicle, ride quality of the vehicle may be improved and so called “rough ride” issues may be precluded. Alternatively or additionally, various valves or alternative compliant mechanisms may be included in the suspension system component, so that desirable performance may be obtained for a range of operating conditions.

Hydraulic fluid in a cylinder's lower chamber is introduced into a back pressure chamber through the outer periphery of an extension-side main valve during a compression stroke of a piston rod. This eliminates the necessity of forming paths by arranging a plurality of discs and a check valve, the paths for introducing into the back pressure chamber the hydraulic fluid in the cylinder's lower chamber that becomes an upstream chamber during the compression stroke. This makes it possible to decrease the axial length of a shaft portion of the piston rod and therefore the entire length of a cylinder, and also downsize a shock absorber.

A shock absorbing and height adjusting structure includes an inner tube, a lower piston assembly and an upper piston assembly. The inner tube includes an upper end, a lower end opposite to the upper end, and an inner space for accommodating a gas. The lower piston assembly includes a lower piston movably inserted into the inner tube, and a lower passage disposed at the lower piston. The upper piston assembly includes an upper piston movably inserted into the inner tube. When the lower passage is opened, the lower piston is moved relative to the lower end, and when the upper piston is forced, the upper piston has movement relative to the upper end toward the lower end to compress the gas.

A suspension assembly for a cycle having improved stability includes a steering fork having a first arm and a second arm, each of the first arm and the second arm having a fixed pivot and a shock pivot, the space between the first arm and the second arm defining a wheel opening. A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has a shock gas spring comprising a shock spring body a shock gas piston having a first gas piston area, a spring unit having a spring gas spring comprising a spring body and a spring gas piston having a second gas piston area. A gas pressure inside the shock gas spring is equal to a predetermined pressure for a user's body weight to produce optimal ride conditions for the user's body weight.

A front fork includes a first tube body having an oil flowing therein, a second tube body provided inside the first tube body, the second tube body having the oil flowing therein, and having the oil flowing in an oil passage formed between the first tube body and the second tube body, a partition member provided in the second tube body and partitioning one end of an oil chamber, a rod extending along an axis of the second tube body through the partition member and being configured to move relative to the partition member, an outer periphery of the rod having a dimple portion recessed toward a center of the rod, and a piston provided at a distal end of the rod and allowing the oil to pass, wherein a boundary between an outer peripheral surface of the rod and the dimple portion is formed by a curved surface.

There is provided an energy absorbing landing gear system for attachment to a vertical landing apparatus. The energy absorbing landing gear system includes a linear damper assembly, and a load limiter assembly coupled to the linear damper assembly, the load limiter assembly having at least one deformable element to enhance an energy absorption capability. When the energy absorbing landing gear system is attached to the vertical landing apparatus, during a landing phase, the linear damper assembly contacts a landing surface, and a piston assembly of the linear damper assembly moves a first compression distance toward the load limiter assembly, and when the linear damper assembly reaches a maximum compression, the linear damper assembly moves a second compression distance into the load limiter assembly, and the at least one deformable element deforms.
