A crossbar assembly for facilitating isolation of a sensor assembly from vibration comprises an outer crossbar segment, an inner crossbar segment, and an isolator. The outer crossbar segment comprises a payload mount interface and an outer isolator interface operable to mount to an isolator. The inner crossbar segment comprises a structure interface and an inner isolator interface operable to mount to the isolator. The isolator can be supported by the outer and inner crossbar segments. The isolator comprises a first wire rope assembly comprising wire ropes extending longitudinally from the outer crossbar segment to the inner crossbar segment, and a second wire rope assembly comprising a wire rope extending circumferentially between the outer and inner crossbar segments. The isolator operates to partially decouple the outer crossbar segment from the inner crossbar segment and dampen vibrations propagating between the outer and inner crossbar segments.

A damping stopper is interposed between two members axially displaced relative to each other and is provided with an elastic body which, when the interval between the two members decreases, is axially compressed by the two members and expands radially outward. In the elastic body, a second member suppressing the expansion is located in one axial region and attached to the outer periphery. When axially compressed by the two members, the elastic body expands while receiving resistance by the second member. The expanding elastic body contacts the side wall of one of the two members.

A method for manufacturing a hollow spring member having a hollow steel spring rod having terminal sealed portions at both ends thereof. Each terminal sealed portion has a rotationally symmetric shape in which an axis passing through a center of the spring rod is an axis of symmetry. Each terminal sealed portion has an end wall portion including an end face; an arc-shaped smoothly curved surface between an outer peripheral surface of the spring rod and the end face, and a hermetically closed distal-end-center closure portion on the axis passing through the center of the spring rod. The method includes forming each of the end portions of the spring rod by forming a chamfered portion on an inner or outer peripheral side of the end portion of a hollow wire, the end portion having an opening portion at a distal end, heating the end portion of the hollow wire having the chamfered portion, and spinning the heated end portion to be gathered toward the axis from the outer peripheral side by a jig. The end wall portion, which includes the distal-end-center closure portion, is formed by the distal end of the end portion being joined together on the axis.

A lattice structure and system for absorbing energy, damping vibration, and reducing shock. The lattice structure comprises a plurality of unit cells, each unit cell comprising a plurality of rib elements with at least a portion of the rib elements including a solid bendable hinge portion for converting energy into linear motion along a longitudinal axis of the respective rib element.

Disclosed is a damper structure in contact with a connection unit for coupling a first coupling structure part and a second coupling structure part, including a damper part formed of an elastic material and at least one fixing part coupled to at least one surface of the damper part and protruding outward, and coming into contact with the connection unit and moving toward the damper part by pressure applied by the connection unit when the connection unit is separated or fastened.

Isolation of a body of a vehicle from vibrational frequencies introduced via electronic axle drive units vehicle is provided. For example, one or more embodiments described herein can comprise a vibration isolation device for a powertrain of an electric vehicle is provided. The vibration isolation device can comprise an inner core configured to operatively attach to an electronic axle drive unit for an axle of the electric vehicle.

A mass damper for a refrigerant pipe is configured to insulate vibration and noise of the refrigerant pipe for the flow of a refrigerant circulating in a vehicle air conditioner system and a mass damper for a vehicle air conditioner system is configured to prevent an external circumferential surface of a casing from cracking due to thermal deformation.

In a method for producing a spring leaf (2) for a leaf spring, in particular a parabolic spring or suspension spring, wherein the spring leaf (2) comprises two end regions, a central region, a top side which is subjected to tensile stress in the operative state, and a bottom side (1) which is subjected to pressure in the operative state, at least one hole (3) is introduced into the bottom side (1). The bottom side (1) is peened locally in the region around the hole (3).

A diaphragm holder for an oleo-pneumatic-type shock absorber includes a tubular body made of thermoplastic material, having a first end arranged to hold a diaphragm provided with flow restricting orifices and an opposite second end defining an arched bottom for withstanding pressure forces. Each of the two ends is provided with a localised mechanical reinforcement element forming an axial stop arranged to allow tensile stressing of the tubular body.
