Gas spring and gas damper assemblies include a flexible spring member. First and second end members are secured to opposing ends of the flexible spring member to form a spring chamber. The second end member includes an end member wall that at least partially defines a damping chamber within the second end member. A damper piston assembly includes a damper piston and an elongated damper rod. The damper piston separates the piston chamber into first and second chamber portions. A pneumatically-actuated control device is disposed in fluid communication with one of the first and second chamber portions. The control device is selectively operable to alter the functionality of the gas spring and gas damper assembly between spring and damper functionality and actuator functionality. Suspension systems including one or more of such gas spring and gas damper assemblies as well as methods of operation are also included.
F16F 9/56 - Means for adjusting the length of, or for locking, the spring or damper, e.g. at the end of the stroke
B60G 11/62 - Resilient suspensions characterised by arrangement, location, or kind of springs having springs of different kinds not including leaf springs having both rubber springs and fluid springs
B60G 15/06 - Resilient suspensions characterised by arrangement, location, or type of combined spring and vibration- damper, e.g. telescopic type having mechanical spring and fluid damper
B60G 15/12 - Resilient suspensions characterised by arrangement, location, or type of combined spring and vibration- damper, e.g. telescopic type having fluid spring and fluid damper
F16F 9/04 - Springs, vibration-dampers, shock-absorbers, or similarly-constructed movement-dampers using a fluid or the equivalent as damping medium using gas only in a chamber with a flexible wall
F16F 9/05 - Springs, vibration-dampers, shock-absorbers, or similarly-constructed movement-dampers using a fluid or the equivalent as damping medium using gas only in a chamber with a flexible wall the flexible wall being of the rolling diaphragm type
F16F 13/20 - Units comprising springs of the non-fluid type as well as vibration-dampers, shock-absorbers, or fluid springs comprising both a plastics spring and a damper, e.g. a friction damper the damper being a fluid damper, e.g. the plastics spring not forming a part of the wall of the fluid chamber of the damper characterised by comprising also a pneumatic spring

Jounce bumper assemblies as well as gas spring assemblies including same
A jounce bumper assembly dimensioned for securement on or along an associated end member of an associated gas spring assembly. The jounce bumper assembly includes a bumper mount dimensioned for securement to the associated end member. A jounce bumper supported on the bumper mount for axial displacement therealong. A biasing element is disposed peripherally about the bumper mount and positioned axially between the jounce bumper and the associated end member. The biasing element has a fully-compressed, solid height that is operative to maintain the jounce bumper assembly in axially-spaced relation to the associated end member under a full jounce load condition. Gas spring assemblies including such a jounce bumper assembly, and suspension systems including one or more of such gas spring assemblies are also included.
F16F 9/00 - Springs, vibration-dampers, shock-absorbers, or similarly-constructed movement-dampers using a fluid or the equivalent as damping medium
F16F 9/58 - Stroke limiting stops, e.g. arranged on the piston rod outside the cylinder
B60G 15/08 - Resilient suspensions characterised by arrangement, location, or type of combined spring and vibration- damper, e.g. telescopic type having fluid spring
F16F 9/05 - Springs, vibration-dampers, shock-absorbers, or similarly-constructed movement-dampers using a fluid or the equivalent as damping medium using gas only in a chamber with a flexible wall the flexible wall being of the rolling diaphragm type
B60G 11/62 - Resilient suspensions characterised by arrangement, location, or kind of springs having springs of different kinds not including leaf springs having both rubber springs and fluid springs
