摘要： The present disclosure relates to a shock absorber (100) including a cylinder (7), a piston rod (2) and a piston (6) attached to the piston rod (2). The piston (6) is arranged in the cylinder (7) and a damping chamber including a damping media is defined in the cylinder (7). The shock absorber (100) further includes a gas spring in functional connection with the damping chamber and at least one characteristic of the gas spring is adjustable by a user-adjustable feature arranged within the piston rod, wherein the user adjustable feature affects the enclosing area of the damping chamber, thereby indirectly affecting the gas spring through the functional connection.

摘要： The present embodiment generally relates to a mechanical assembly which modifies and enhances the performance of a critical portion of the parts which comprise an air spring assembly. A key element common with an air spring assembly is the precharge chamber. This chamber is filled at the factory with compressed gas and along with a floating piston and a piston rod, creates the basic air spring assembly. Although this is a sealed chamber, the potential for air leakage is well documented. The inability to maintain the design gas pressure in the precharge chamber requires the chamber to initially be overcharged to remain functional even with the slow loss of air charge. The present invention demonstrates how the precharge assembly found in all such air springs can be modified and, with the addition of a few parts, be capable of maintaining the precharge pressure at an optimum level.

摘要： A vehicle damper assembly is disclosed. The damper includes a cylinder having an inner diameter (ID). A rod and a piston, the piston coupled to the rod and configured to divide the cylinder into a compression side and a rebound side. An electronic valve assembly including an electronic valve body coupled with the rod on the compression side of the piston. The electronic valve body having an electronic valve body outer diameter (OD). A boost valve having a boost valve body, a boost valve area located between the electronic valve body and the boost valve body, the boost valve having a boost valve OD. The boost valve OD is larger than the electronic valve body OD, such that the boost valve is configured to allow the electronic valve assembly to operate within said cylinder ID that is too large for the electronic valve body OD.

摘要： A vehicle damper is described. The vehicle damper includes: a cylinder; a piston within the cylinder; a working fluid within the cylinder; a reservoir in fluid communication with the cylinder via the working fluid, the reservoir operable to receive the working fluid from the cylinder in a compression stroke; a valve in a flow path between the cylinder and the reservoir; and a remotely-operable valve having a position allowing the working fluid to significantly by-pass the valve.

摘要： A damper valve with an adjustable effective stiffness of a shim. The damper valve includes a piston. The piston has a fluid path formed therethrough. A shim is disposed proximate the fluid path formed through the piston. A stiffness adjustment feature is coupled to the shim, and the shim is disposed between the piston and the stiffness adjustment feature. The stiffness adjustment feature is configured to adjust the effective stiffness of the shim without affecting a preload applied to the shim.
