| 20080303196 | UPPER STRUT MOUNT ASSEMBLY - An upper strut mount assembly includes a cylindrical member. The cylindrical member includes a top portion, a bottom portion, and an annular portion. A bottom surface of the annular portion abuts at least a top portion of a rolling member thereby allowing the spring seat to rotate relative to at least the cylindrical member. A first resilient member includes a first annular portion and a second annular portion. A bottom surface of the first annular portion abuts a top surface of the cylindrical member annular portion. A second resilient member includes a first annular portion and a second annular portion. A bottom surface of the first annular potion abuts a top surface of the cylindrical member annular portion. An exposed surface of the second annular portion of the second resilient abuts an exposed surface of the second annular portion of the first resilient member. | 12-11-2008 |
| 20130009350 | Semiactive Wheel Suspension - The invention relates to a wheel suspension which has a spring system ( | 01-10-2013 |
| 20160052358 | INSULATOR FOR SUSPENSION DEVICE - The invention relates to an insulator for a suspension device having a coil spring and a spring seat for supporting the coil spring. The insulator is provided between the coil spring and the spring seat and comprises at least an annular seat groove in which a coil end of the coil spring is seated. The insulator comprises at least an adjustment recess formed in the insulator along the seat groove so as to open at a wall surface of the insulator where the seat groove opens. The adjustment recess is configured to allow the seat groove to be deformed to increase a radial groove width between inner and outer edge ends of the seat groove when the coil end enters into the seat groove. | 02-25-2016 |
| 20160107497 | SPRING ISOLATORS AND SUSPENSION SYSTEMS INCORPORATING SAME - A spring isolator for a wheel suspension may include a first side configured to rest on a spring plate of the suspension. The spring isolator may also include a second side, opposite the first side, configured to receive a last coil of a coil spring of the suspension to support the coil spring on the spring plate. The first side may have at least one cavity extending through a thickness of the isolator toward the second side. An elasticity of the isolator between the first and second sides may prevent the last coil from breaking contact with the second side during operation of the suspension. | 04-21-2016 |
| 267034000 | Coil and fluid pressure | 3 |
| 20100156012 | HYDRO-PNEUMATIC SUSPENSION SYSTEM - A suspension system for a vehicle has an upper control arm and an associated lower control arm for mounting a wheel on the vehicle body. A hydro-pneumatic spring is connected between one of the control arms and the vehicle body. A compensating spring is associated with the hydro-pneumatic spring and is operable to act in opposition to the force exerted by the hydro-pneumatic spring as the hydro-pneumatic spring approaches full extension. | 06-24-2010 |
| 20110024957 | VEHICLE HEIGHT ADJUSTING APPARATUS - A vehicle height adjusting apparatus of a hydraulic shock absorber has a hydraulic pump carrying out a pumping action by an extending and retracting motion of a piston rod with respect to a damper tube so as to feed a working fluid to a jack chamber of a hydraulic jack, and a blow valve releasing a jack pressure of the jack chamber which is pressurized by a plunger of the hydraulic jack exposed to a spring load on a suspension spring. | 02-03-2011 |
| 20110254209 | STRUT ASSEMBLY WITH AIR SPRING - A strut assembly includes a damper having a housing and a rod moveable relative to the housing along a longitudinal axis. The strut assembly includes a flexible membrane configured to receive a pressurized gas to form an air spring. A coil spring defines an inner diameter with the housing disposed within the inner diameter to permit relative movement between the coil spring and the housing. The coil spring is at least partially disposed outside the flexible membrane relative to the longitudinal axis. | 10-20-2011 |
| 267035000 | Rubber type and fluid pressure | 3 |
| 20140091504 | GAS SPRING ASSEMBLY AND METHOD - A gas spring assembly includes an unreinforced flexible wall formed from a polymeric material and an external reinforcing structure extending lengthwise along and around the periphery of the unreinforced flexible wall. The external reinforcing structure is capable of extending and collapsing together with corresponding extension and compression of the flexible wall. The gas spring assembly also includes opposing end members. The external reinforcing structure can be formed from a plurality of interconnecting wall segments that at least partially define a plurality of openings extending through the external reinforcing structure. A suspension system is also included. | 04-03-2014 |
| 20140117597 | AIR SPRING FOR RAILROAD CAR - An air spring for railroad cars includes an air spring part formed by an upper support on a vehicle body side, an intermediate support arranged therebelow, and a diaphragm made of rubber and extending between the upper support and the intermediate support; and an elastic mechanism b formed by a rubber mass | 05-01-2014 |
| 20140374972 | AIR SPRING - A vehicle air spring with an elastomer material air-tight tensioned air spring bellows arranged between an air spring cover and rolling piston. The air spring bellows delimiting, with the air spring cover and the air spring rolling piston, a working chamber filled with compressed air. The air spring bellows rolling away under formation of a rolling fold on the air spring rolling piston and fastening to the air spring cover under formation of a second fold, and having an elastomer element provided as an anti-roughness bearing. The elastomer element is arranged between a first and second piston part of the air spring rolling piston, the second part arranged coaxially to the first. The rolling surface for the air spring bellows is provided on the first piston part and on which the air spring bellows is fastened by a clamping element. The second piston part is mountable on a vehicle chassis. | 12-25-2014 |
