Mounting assembly dimensioned for securement between a vehicle structure and a gas spring and damper assembly include a first end plate securable to the vehicle structure. A second end plate is attached in substantially fixed relation to the first end plate such that a mounting cavity is disposed therebetween. A connector housing is disposed within the mounting cavity and operatively connectable to the gas spring and damper assembly. A first bearing assembly is disposed between the connector housing and the first end plate and permits rotation of the connector housing relative to the first end plate while transferring forces acting longitudinally therebetween. A second bearing assembly is disposed between the connector housing and the second end plate and permits rotation of the connector housing relative to the second end plate while transferring forces acting longitudinally therebetween. Gas spring and damper assemblies are also included.

A gas spring seal cap secured a first end member of a gas spring and damper assembly such that a substantially fluid-tight connection is formed therebetween. Seal cap includes a seal cap body with a first end surface portion and a second end surface portion. An electrical conductor extends through seal cap body that includes a first terminal end conductively accessible from along the first end surface portion and a second terminal end that is conductively accessible from along the second end surface portion of seal cap body. Electrical conductor includes a substantially impermeable portion having a substantially fluid-tight connection with seal cap body. The substantially impermeable portion of electrical conductor substantially inhibits fluid communication across seal cap body through electrical conductor. Gas spring and damper assemblies as well as methods of assembly are also included.

End mount assemblies include a mounting bracket dimensioned for securement to an end member of a gas spring and damper assembly. The end mount assembly can include an inner mounting element dimensioned for securement to an elongated damping rod of the gas spring and damper assembly. A first plurality of bushing elements can be operatively disposed between the inner mounting element and the mounting bracket. A second plurality of bushing elements can be operatively disposed between the inner mounting element and the end member. Gas spring and a damper assemblies including such an end mount assembly as well as suspension systems and methods of assembly are also included.

A suspension apparatus includes a main body; a first arm configured to support a wheel with respect to the main body; a second arm spaced apart from the first arm and including a guide rail; a shock absorber disposed between the second arm and the main body; a first support member disposed on one side of the shock absorber and rotatably connected to the main body; a second support member disposed on another side of the shock absorber and seated on the guide rail; and a height of the main body is adjusted by movement of the second support member along the guide rail.

An air suspension assembly comprises a top and a bottom disposed on a center axis and spaced apart from one another. A bellows of an elastomeric material extends between a first end secured to the top and a second end secured to the bottom defining a chamber. The chamber extends between the top, the bottom, and the bellows for containing pressurized air, whereby a pressure of the pressurized air is controlled based on a force applied. The bellows has an interior surface and an exterior surface and including a plurality of convolutes extending between the first end and the second end. Each convolute of the plurality of convolutes includes a pair of outer lobes and an inner lobe with each outer lobe of the pair of outer lobes having an outer lobe thickness extending between the interior surface and the exterior surface of the bellows.

A suspension includes: a cylinder; a piston rod including a piston provided at one end-side, and inserted in the cylinder together with the piston; an outer tube part opened at the one end-side, a position of which relative to the piston rod is fixed at the other end-side, and configured to receive therein at least a part of the cylinder; and a tubular rolling diaphragm having one end disposed at the cylinder and the other end fixed to the outer tube part, and configured to roll in conjunction with displacement of the piston rod with respect to the cylinder. The rolling diaphragm becomes convex toward the other end-side of the outer tube part and is accommodated in the outer tube part, upon contraction of the suspension.
