The first and second engagement surfaces of the respective first and second pieces of the axle seat assembly are positioned and configured to engage one another to removably and reversibly secure with the use of a fastener the first piece to the second piece to form an axle seat assembly.

A vehicle includes a vehicle structure, a wheel assembly, a control arm that is connected to the wheel assembly and the vehicle structure by pivot joints, and an active suspension actuator that is connected to the control arm and to the vehicle structure. The vehicle also includes an air reservoir that includes a first port and an air spring that supports the vehicle structure with respect to the control arm and is able to compress and expand. The air spring includes an internal working volume, the air spring includes a second port that is in fluid communication with the internal working volume, and the second port is connected to the first port to allow exchange of air between the internal working volume of the air spring and the air reservoir in response to compression and expansion of the air spring.

The invention relates to a working machine comprising a working machine frame, at least one propulsion axle having an elongated main body comprising a first end portion, a second end portion and a center portion arranged between the first and second end portions. The elongated main body has a main body length (MBL) extending from the first end portion to the second end portion. The working machine further comprises a propulsion axle suspension arrangement arranged between the working machine frame and the propulsion axle, the propulsion axle suspension arrangement comprising a first suspension device and a second suspension device arranged on opposite sides of a center of the elongated main body. The first and second suspension devices are arranged in the center portion of the elongated main body.

Flexible spring member and end closure assemblies include a flexible spring member-defining a spring chamber. An end closure body includes an outer peripheral surface portion and an elongated damping passage extending axially into end closure wall in a spiral arrangement about longitudinal axis. End closure body is positioned along an end of flexible spring member with flexible wall permanently attached along outer peripheral surface portion such that a substantially fluid-tight joint is formed between flexible spring member and end closure body. Gas spring and gas damper assemblies as well as methods of assembly are also included.

Gas spring end members include an end member wall with a longitudinal axis. The end member wall includes an end wall portion and an outer wall portion. The outer wall portion extends peripherally about an axis and is dimensioned to receivingly engage a flexible spring member. Rib wall portions are spaced around the axis with each of the rib wall portions projecting axially from the end wall portion toward a rib end surface portion. The rib wall portions also include a rib edge surface portion spaced inward from an inner side surface portion of the outer peripheral wall portion such that a gap is formed therebetween. Gas spring assemblies including one or more of such end members, and suspension systems including one or more of such gas spring assemblies are also included.

A Retrofittable Air Suspension Brackets assembly comprises an air spring retained between an Upper Air Spring Mount and a Lower Air Spring Bracket. The Upper Air Spring Mount is attached to Upper Frame Brackets that are held in place by two U-Bolts, which also secure the Lower Air Spring Bracket and a Cradle Structure which limits movement of the vehicle frame member.

An automotive vehicle mount includes a frame that has a cross beam, a longitudinally extending first side frame rail, and a longitudinally extending second side frame rail. Each of the frame rails includes mounting holes for a suspension system. The automotive vehicle mount further includes a first side mount bracket mounted to the first frame rail and a second side mount bracket mounted to the second frame rail. The automotive vehicle mount further includes a first air bag pivotally mounted to the first side mount bracket to support the cross beam, and a second air bag pivotally mounted to the second side mount bracket to support the cross beam.

A suspension system for liftable steerable axles has at least one steering knuckle; at least one pistonless bellows air spring actuator (ie., damper air spring); and a steering axle structure that has, at each end, a kingpin housing boss, a kingpin fixed into the kingpin boss, and a pair of steering knuckles that rotate around the kingpin and are supported by the kingpin housing; wherein the steering knuckles are connected at the bottom of each other side to side by a tie rod assembly that respond to each others rotational inputs; and further having the damper air spring being connected to the steering knuckle so that, given a supplied pneumatic air force, the damper air spring stabilizes and dampens the steering road inputs when in motion.

A device for fastening an air spring to a body portion of a motor vehicle, at least comprising an air spring cover, wherein the air spring cover comprises at least one fastening means, by means of which the air spring can be connected to the body portion of the motor vehicle, wherein, for attachment of the air spring, the fastening means is plugged through an opening of the body portion and is fixed to said body portion in a force-fitting manner by a securing element, wherein a first and a second plastics part are provided for acoustic decoupling of the air spring, wherein the first plastics part, is clamped between the body portion and the securing element, and the second plastics part is provided so as to be positioned below the body portion.

An air spring includes an air spring bellows extending along a longitudinal axis, an outer guide for the air spring bellows that extends at least partially around the air spring bellows and around the longitudinal axis, and a bellows extending at least partially around the air spring. In embodiments, the bellows includes a first bellows section and a second bellows section along the longitudinal axis, which extends at least partially around the outer guide. In embodiments, the bellows has, between the first bellows section and the second bellows section, a support configured for coupling to the outer guide, the support being mounted loosely on the outer guide in a first longitudinal axis direction and being decoupleable from the outer guide in a second longitudinal axis direction. The invention can provide, inter alia, an air spring with an increased lifespan.
