20080251332 | ANTI-BLAST AND SHOCK REDUCTION BUFFER - A device for mitigating shock loads utilizes load-fitted and form-fitted fluid capsules. Each capsule includes a pair of substantially flat end caps. Further, the end caps are parallel and are centered on a common axis. In each fluid capsule, high-tension members interconnect the two end caps to limit the axial distance between the end caps to less than a predetermined value. For each capsule, a membrane interconnects the peripheries of the end caps to enclose the fluid capsule between the end caps. Also, each fluid capsule includes a valve through the membrane to allow fluid flow between fluid capsules when a pressure on the valve exceeds a predetermined level. When a force is applied against a fluid capsule, the membrane deforms before fluid flows from the capsule to mitigate shock loading. | 10-16-2008 |
20100187060 | Spring Strut with Control Sleeve - A suspension strut with an elastomer block for a wheel of a vehicle, in particular, for a wheel of a motorcycle is provided. The spring constant of the elastomer block, which interacts with an additional spring element, can be changed by introducing a control sleeve between the elastomer block and the body of the suspension strut. The elastomer block further is effectively disengaged from the additional spring element when the control sleeve is in a lower end position, so that the spring rate is determined only by the additional spring element. | 07-29-2010 |

20130146408 | DUST SEAL STRUCTURE FOR SHOCK ABSORBER - A dust seal structure for a shock absorber includes a cylindrical base shell, in which a piston valve and a piston rod are embedded, a cap member covering one end of the base shell, an oil seal sealing the base shell, and a dust sealing member blocking dusts from being introduced at one side of the oil seal. | 06-13-2013 |
20130220751 | DUST LIP FOR SHOCK ABSORBER - Provided is a dust lip for a shock absorber, which is provided between a dust cover and a piston rod to prevent foreign substances from flowing into an oil sealing unit in twice and eliminate noise generated by mutual interference between a piston rod and a bumper rubber. The dust lip for the shock absorber includes: a piston rod; a base shell through which a part of the piston rod passes such that the piston rod is exposed to one side; a cap member covering one end of the base shell through which the piston rod passes; a bumper rubber attached to an outer periphery of the exposed portion of the piston rod; and a dust lip provided between the piston rod and the cap member to remove a gap between the piston rod and the cap member. | 08-29-2013 |

The wear bands include multiple layers such as a base metal layer sandwiched between an outer layer and an intermediate layer along with a solid lubricant layer disposed opposite the intermediate layer from the base metal layer. The outer layer engages an interior surface of the strut housing, which slidably accommodates a rod. The solid lubricant layer, which is the innermost layer, engages an outer surface of the rod so that the wear band is sandwiched between the rod and the housing and provides a solid lubricant layer for engaging the sliding rod. | 02-19-2015 |
