A pneumatic control system includes a manifold that defines: a channel for conveying a fluid, a discharge port, a drain port, and an expansion chamber defining a chamber axis. The discharge port defines a flow axis extending between a first end and second end and a receiving region at the second end. The pneumatic control system also includes a filter assembly with a filter member disposed in the expansion chamber, and an actuator configured to selectively control fluid communication between the channel and the discharge port. The chamber axis is substantially coplanar with the flow axis. A filter cap assembly includes a filter cap body enclosing an end of the expansion chamber and selectively removable from the manifold to provide access to the filter assembly. A purge valve body is configured to selectively control fluid flow between the expansion chamber and the drain port.

A spring assembly for a non-rail wheeled or tracked vehicle is provided. The spring assembly includes a piston, and a sleeve with variable thickness. The sleeve is made from an unreinforced synthetic elastomeric material and being free of reinforcing fibers. The sleeve is coupled with a plurality of end components and defines a deformable pressure vessel, and the deformable pressure vessel supplies a support force.

A mounting apparatus for vehicle suspension ball joints that are firmly affixed for operation, are easily adjustable in a generally vertical direction for precise tuning of suspension geometry for dynamic performance in multiple axes using an array of cylindrical shims tuned to match fastener distance and height with a socket that has mounting bolts that engage a scalloped cap.

A bumper cap for a damper, the damper including an outer tube with a tube end. A rod extending through the tube end. The damper including a damping fluid, such as a hydraulic oil, that is movable within the damper in response to movement of the rod to provide a damping effect. The bumper cap has a cup shaped body having a side wall and a base, the side wall having an inner surface and an outer surface, the inner surface having a dimension that is sized to be press fit over the outer tube. The base of the bumper cap has a through hole in the base, the through hole configured to have the rod pass therethrough. The base has at least one fluid passage extending away from the through hole that is in fluid communication with a fluid reservoir in the side wall.

A lightweight suspension assembly for a vehicle includes a suspension upright or knuckle provided with a bearing connection interface for receiving at least part of a wheel bearing, and with a first molded portion made of a first polymeric material; the assembly further includes at least one arm having a second molded portion made of a second polymeric material, and at least one joint member coupling the arm to the suspension upright/knuckle in such a manner to allow a relative rotation between the arm and the suspension upright/knuckle about at least one rotation axis (B); the first and second molded portions are arranged onto a first surface and, respectively, a second surface of the joint member, in such a manner that the first and second molded portions are coupled in a non-releasable manner to the joint member.

A method for forming an air spring for a vehicle including a frame coupled to the air spring includes heating an elastomeric base material to a melting point of the elastomeric base material, thereby forming a melted elastomeric base material, forming a sleeve from the melted elastomeric base material, the sleeve being substantially free of textile reinforcing fibers, and engaging the sleeve with end components, the sleeve and the end components defining a deformable pressure vessel, where the deformable pressure vessel supplies a supporting force.

A collar includes a tubular portion and a flange portion extending radially outward from an end portion of the tubular portion, first and second corner portions formed by the tubular portion and the flange portion are provided with first and second curved surface portions formed as concave curved surfaces, an end portion of the trailing arm is provided with a collar through-hole into which the collar is inserted, and an edge portion of the collar through-hole is provided with a through-hole side curved surface portion formed as a convex curved surface coming into contact with the first and second curved surface portions.

A polyamide resin composition contains a polyamide resin and an inorganic filler. 90 mass % or more of polyamide 66 is contained relative to 100 mass % of the polyamide resin. The inorganic filler content is ≥30 mass % relative to 100 mass % of the composition. The composition has a solidifying point of ≥210° C. The composition has a spiral flow value of ≥60 cm when the inorganic filler content is ≥30 mass % and <40 mass %, ≥40 cm when the content is ≥40 mass % and ≤50 mass %, and ≥20 cm when the content is >50 mass % and ≤70 mass %. The composition has a strain of ≤3.8% in a 1000-hour tensile creep test under 120° C. and 60 MPa. The composition has a formic acid relative viscosity (VR) of 30<VR<40.

A bush for vehicles and a method for assembling the same, may include an elastic body closely attached to an external surface of an internal structure, a bearing configured such that the elastic body is coupled to an internal surface of the bearing, a housing coupled to an external surface of the bearing to come into sliding contact with the bearing and mounted on a target object on which the housing is to be mounted, and seals mounted between both end portions of the bearing and both end portions of the housing to seal a sliding contact surface between the bearing and the housing.

A strut bearing assembly for a vehicle includes: an insulator coupled to a vehicle body; a first case disposed to face the insulator; a second case rotatably coupled to the first case; a friction reduction unit disposed between the first case and the second case, and configured to reduce friction between the first case and the second case; and a coupling unit disposed in the insulator and the first case, melted by heat, and coupling the insulator and the first case to each other.
