The connecting rod is a non-ferrous material connecting rod that is produced by an extrusion process. The connecting rod is welded to the first and second end joint assemblies using a welding process which produces a full face weld. The first and second end joint assemblies can include an eye which is manufactured from an extrusion process and the eye can also be manufactured from a non-ferrous material. | 01-05-2012 |
| 20120001373 | SEGMENTED ELASTOMERIC VIBRATION MOUNT WITH EDGE CONTROL - A mount assembly has a plurality of elastomeric members having a separator plate disposed between adjacent elastomeric members. The separator plate defines a flange which extends toward an adjacent separator plate to confine the elastomeric layer. A mounting plate is located at both ends of the mount assembly and can be used to attach the mount assembly to two components. | 01-05-2012 |
| 20110116731 | CONFINED HEAVY DUTY BUSHING FOR HIGH LOAD APPLICATIONS - An elastomeric bushing includes an inner component, a pair of outer components and an elastomeric bushing disposed between the inner component and the pair of outer components. An annular gap is defined between the pair of outer components. When the elastomeric bushing is assembled into a housing, the width of the gap is reduced or eliminated increasing the compression of the elastomeric bushing. | 05-19-2011 |
| 20100059958 | Heavy vehicle sway bar with redundancy (backup safety feature) - A sway bar assembly has a tubular bar extending between two mounts. A pair of brackets mount the center section of the tubular bar to a vehicle. A first solid bar extends from the first mount to one of the brackets and a second solid bar extends from the second mount to the other bracket. The solid bars provide a redundancy of back-up features for the sway bar assembly. | 03-11-2010 |
| 20090315235 | AXIAL SHEAR-LEG ISOLATOR - An elastomeric isolator has an elastomeric body which incorporates an inner structural member that extends through an outer structural member. The elastomeric body includes an axial shear leg extending between the inner and outer structural members that undergo shearing stresses during deflection of the elastomeric isolator. The inner structural member includes radial flanges which are axially offset from radial flanges of the outer structural member. The axial shear leg extends between the pair of radial flanges and is bonded to them at a position outside of the outer structural member. With this configuration compression of the shear hub during high loads is avoided. | 12-24-2009 |
| 20090273127 | HYDRAULICALLY DAMPED BODY MOUNT WITH BOLT-THROUGH CONSTRUCTION - A mount has an inner metal and an outer metal with an elastomeric bushing disposed between them. The elastomeric bushing includes a first pair of interconnected passages to control the damping rate during axial motion and a second, separate pair of interconnected passages to control the damping rate during motion orthogonal to the axial direction. | 11-05-2009 |
| 20090249581 | CURLED BUSHING WITH TORSIONAL SLIP - An elastomeric bushing assembly has an inner component, an outer component and an elastomeric bushing disposed between the inner and outer components. A bearing engages the inner component and is disposed between the elastomeric bushing and the inner component. The bearing allows pivoting of the inner component with respect to the bearing. A low friction coating is disposed between the inner component and the bearing to provide a low friction interface. | 10-08-2009 |
| 20090166939 | Very high damping body mount, subframe mount or engine mount with bolt-through construction - A hydraulic mount has an upper support member and a lower support member. An upper elastomeric spring and a lower elastomeric spring are disposed between the upper support member and the lower support member to define an upper fluid chamber and a lower fluid chamber. A channel extends between the upper and lower chambers. During compression and extension of the hydraulic mount, fluid transfers between the upper and lower chamber to provide a damping force for the hydraulic mount. | 07-02-2009 |
| 20090160111 | VERY HIGH DAMPING MOUNT WITH BOLT-THROUGH CONSTRUCTION - A hydraulic mount has an upper support member and a lower support member. An upper elastomeric spring and a lower elastomeric spring are disposed between the upper support member and the lower support member to define an upper fluid chamber and a lower fluid chamber. A channel extends between the upper and lower chambers. During compression and extension of the hydraulic mount, fluid transfers between the upper and lower chamber to provide a damping force for the hydraulic mount. | 06-25-2009 |
| 20090072458 | SELF-CONSTRAINED DYNAMIC DAMPER - A vibration damper assembly includes a mass, a retaining member and an elastomeric member bonded to the mass and the retaining member. The retaining member includes a constraining device that prohibits the mass from being disassembled from the retaining member should the elastomeric member or the bond deteriorate. | 03-19-2009 |
| 20090020976 | Bushing having high axial spring rate and method of manufacturing - A high axial spring rate spring pivot bushing has an inner metal to which is press fit a ferrule at one end. An outer metal is disposed around the inner metal and an elastomeric bushing is located between the inner metal, the ferrule and the outer metal. The spring pivot bushing is manufactured by pressing the ferrule on the inner metal, placing the inner metal, ferrule and outer metal in a mold and then injecting an elastomeric material to create the elastomeric bushing. | 01-22-2009 |
| 20080277847 | BUSHING HAVING SELF-LUBRICATING OVERMOLD - An elastomeric bushing has an outer structural member within which is located an outer elastomeric member, a self-lubricating elastomer and an inner structural member. The self-lubricating elastomer is located between the inner structural member and the outer structural member and is overmolded with the outer elastomeric member to provide adhesion between the self-lubricating elastomer and the outer elastomeric member. The self-lubricating elastomer can be located between the outer structural member and the outer elastomeric member or between the inner structural member and the outer elastomeric member. | 11-13-2008 |
