A bushing is disclosed for pivotally mounting an end portion of an axle-supporting beam of a vehicle suspension system to a hanger bracket of the vehicle with a pair of wear pads positioned between sides of the end portion of the beam and the hanger bracket, where the pair of wear pads each has a central opening defined by an inner edge. The bushing includes a tubular body having a longitudinal axis, a first end portion, a second end portion and a beam support portion positioned between the first and second end portions. A first resilient wear pad retainer extends radially from the first end portion of the body and a second resilient wear pad retainer extends radially from the second end portion of the body. Each of the first and second wear pad retainers are configured to move into a deflected position when contacted by an inner edge of a wear pad central opening and to rebound back to an original position afterwards as the wear pad is positioned on the first or second end portions of the body so that the wear pad is secured to the bushing.

A tubular containment part used in a flywheel containment assembly, wherein the tubular containment part is built up of easily configurable layers of different materials and wherein the containment casing is included a spirally wound tubular structure formed from layers made of one or more different materials. The invention further relates to a method for manufacturing such a tubular containment part.

The present disclosure relates to a flywheel system (1), comprising a ring-shaped flywheel rotor (3), arranged on a rotation axis (7); and a substantially cylindrical casing (2), enveloping the flywheel rotor (3) at least in a radial direction to contain the flywheel (3) in case of a calamity. The flywheel system (1) further exhibits the feature that the casing (2) comprises and having at least one inward protruding bumper (8) defining a variation from the circular shape in cross section of the casing wall (5) surrounding the flywheel rotor (3). The casing wall (5) may itself be circular and the bumper (8) can define a deviation relative to the circular shape thereof, to enhance deceleration of the flywheel rotor (3), if, in case of an accident or calamity, the flywheel rotor (3) comes loose.

A damper is provided for responding to relative movement of arms to which the damper is coupled. The damper includes a member, springs, a first housing and a second housing. The first housing includes a first body and first bellows affixed to the member and the first body by first joints to define a first interior. The second housing includes a second body and second bellows affixed to the member and the second body by second joints to define a second interior. The first and second interiors are configured to contain fluid charged therein and the member is configured to permit bi-directional flows of the fluid between the first and second interiors responsive to the relative movement of the arms and in opposition to an elasticity of the springs.

A spring assembly includes a coil spring having one or more helical coils between two longitudinally spaced ends, and an attachment site disposed at at least one of the longitudinally spaced ends. The attachment site includes a casing enclosing the at least one of the longitudinally spaced ends, the casing having a casing passage therethrough between a first side and a second side. The attachment site also includes a washer disposed on the first side and having a washer passage aligned with the casing passage, and a base disposed on the second side and having a base passage aligned with the casing passage.

An air spring is configured for use in connection with a motor vehicle. The air spring includes a first end cap. The first end cap is configured to attach to a first vehicle component. The air spring also includes a piston member. The piston member is configured to attach to a second vehicle component. The piston member is movable toward and away from the first end cap in an axial direction during use. The air spring also includes an air sleeve that is coupled to the first end cap at a first end by use of a first crimp ring and to the piston member at a second end by use of a second crimp ring to form a chamber configured to receive pressurized air. The air spring further includes a transition collar that is configured to placed radially outward from either the first or second crimp ring. The transition collar includes a sloped or tapered exterior surface that allows a portion of the air sleeve to engage and roller over the exterior surface of the transition collar to reduce wear to the air sleeve.

A magnetic suspension shock absorber is composed of an outer telescopic cylinder, a shaft rod, an inner telescopic cylinder and two sets of magnetic suspension units. Each set of magnetic suspension unit contains two magnets, and the corresponding surfaces of two magnets of each magnetic suspension unit are the same magnetic polarity. The magnets of two sets of magnetic suspension units are respectively combined with the outer telescopic cylinder, the shaft rod and the inner telescopic cylinder. Thus, when the inner telescopic cylinder is impacted by external force, two magnets of one magnetic suspension unit will be close to each other and produce mutual repulsion, thus achieving buffering and shock absorbing effects.

Provided is a spring sleeve for a piston cylinder unit, wherein the spring sleeve is adapted to receive a spring, at least partially, and to guide it, wherein the spring sleeve has a cylindrical sleeve inner surface. The embodiment further relates to a cylinder for a piston cylinder unit, wherein the cylinder) is adapted to be arranged inside a spring of a piston cylinder unit. The embodiment also relates to a piston cylinder unit, including a cylinder, a spring arranged concentrically around the cylinder, and an inner spring sleeve and outer spring sleeve each arranged concentrically around the spring, wherein the cylinder and the spring are arranged inside the inner spring sleeve and the outer spring sleeve. Finally, the embodiment relates to a method of manufacturing such a piston cylinder unit.

The present disclosure relates to a flywheel system (1), comprising a ring-shaped flywheel rotor (3), arranged on a rotation axis (7); and a substantially cylindrical casing (2), enveloping the flywheel rotor (3) at least in a radial direction to contain the flywheel (3) in case of a calamity. The flywheel system (1) further exhibits the feature that the casing (2) comprises and having at least one inward protruding bumper (8) defining a variation from the circular shape in cross section of the casing wall (5) surrounding the flywheel rotor (3). The casing wall (5) may itself be circular and the bumper (8) can define a deviation relative to the circular shape thereof, to enhance deceleration of the flywheel rotor (3), if, in case of an accident or calamity, the flywheel rotor (3) comes loose.

A torque strut engine motor mount protective cover includes an outer rubber bushing cover and an inner rubber bushing cover, wherein the outer and inner rubber bushing cover delineate a cup-shaped bodies. The outer and inner rubber bushing cover each includes a bolt fastening eyelet, a first elongated body, and a second elongated body. the bolt fastening eyelet traverses through a base plate of the inner rubber bushing cover and the outer rubber bushing cover. The first elongated body and the second elongated body that are terminally connected to the base plate so that the first and second elongated bodies can be inserted into the rubber bushing. Resultantly, the outer rubber bushing cover and the inner rubber bushing cover are concentrically mounted to each other and positioned offset from each other about the torque strut engine motor mount as a bolt is inserted through the bolt fastening eyelet.
