A fluid-filled tubular vibration-damping device comprising: an inner shaft member and an outer tube member connected by a main rubber elastic body so as to provide a sealed zone filled with a non-compressible fluid therebetween; and a partition wall partitioning the sealed zone axially. An outer peripheral side of the partition wall is fixed to the outer tube member while an inner peripheral side of the partition wall is constituted by an annular partition wall rubber disposed around the inner shaft member in a movable manner axially. Sealing tube parts are integrally formed with an inner peripheral portion of the partition wall rubber and project toward axially opposite sides. Fitting parts thicker than the sealing tube parts are integrally formed with distal ends of the respective sealing tube parts and are externally fitted around the inner shaft member in a slidable manner.

A flywheel for example to a sport training or a rehabilitation machine, is linked to a hauling cable through a system of pulleys, including, in a well-known way, at least a disk-shaped part (4) rotating about a central axis (5) and incorporates a series of weights (6) that, depending on their distribution and their own weight provide a given moment of inertia. Starting from this already known configuration, the flywheel (1) is distinguished in that it has a moving coupling means (7) that allows the variation of the position of the weights (6) on the disk (4) of the wheel and to modify the moment of inertia, without it being necessary to withdraw or replace any of the weights (6) or the disk (4).

Some of the present apparatuses include a frame defining first and second supports and at least a portion of a rigid tank mount laterally offset from the first and second supports, where the first support is configured to be pivotally coupled to a vehicle such that the frame is movable relative to the vehicle between a first position in which the second support is spaced apart from the vehicle and second position in which the second support is coupled to the vehicle. Some apparatuses include a frame mount having a flange defining a bounded opening configured to receive a fastener and a post extending from the flange and away from the opening, where the first support is configured to be pivotally coupled to the flange via the fastener and the second support is configured to be coupled to the post when the frame is in the second position.

A strut suitable for use in parallel manipulator and other applications utilizes an actuation member that is subjected to a quasi-static axial tensioning force to effectively preload the strut to provide axial stiffness and bending flexibility at one or more ends of the strut.

A vibration reduction assembly (200) including: (i) a shaft (240); (ii) a first component (210) positioned along the shaft and having a first face (212) comprising a plurality of magnets (230) positioned to alternate between a magnet having a first magnetic pole (232) at the first face and a magnet having the opposite magnetic pole (234) at the first face; and (iii) a second component (220) positioned along the shaft and having a first face (222) comprising a plurality of ferromagnetic extensions (260), wherein the first face of the first component is separated from the first face of the second component by a gap (280) having an adjustable first distance, and wherein a pair of the plurality of magnets interact via magnetic force with a respective one of the ferromagnetic extensions to reduce vibrations from a drivetrain to a housing portion of the personal care device.

A vibration damper for a chassis of a vehicle including a damper tube which is filled at least partially with damping liquid and in which a piston rod can be moved to and fro. A working piston is movable with the piston rod, by way of which working piston the interior space of the damper tube is divided into a piston rod-side working space and a working space which is remote from the piston rod. At least one additional attachment unit is connected to the damper tube in a fluid-tight manner by way of a throughflow element. The throughflow element is arranged on the damper tube in a direction which differs from the radial direction of the damper tube.

The present disclosure relates to a vibration reduction device, an electronic device and mobile equipment containing same. The vibration reduction device comprises: a first fixing component (10) which is a frame structure (11); a second fixing component (100) arranged in the center or near the center position of the first fixing component (10); and a vibration reduction connecting component (50) positioned between the first fixing component (10) and the second fixing component (100) and used for connecting both together. The vibration reduction connecting component (50) comprises a vibration reduction connecting frame (53) connected to the frame structure (11), and an inverted U-shaped structure (51) positioned in the vibration reduction connecting frame (53), connected to the lower part of the vibration reduction connecting frame (53) through supporting legs and connected with the second fixing component (100). The vibration reduction device of the present disclosure can provide excellent vibration reduction and impact-prevention protection for electronic products and precision electronic equipment. It is especially able to protect electronic products and precision electronic equipment installed on mobile equipment, such as a vehicle, against physical damage while under severe travelling conditions, as well as ensure their normal operation. The vibration reduction device according to the present disclosure not only has a simple structure and occupies little space, but also has simple installation and long service life, and can be suitable for varying load conditions.

A damper assembly for a bicycle wheel assembly may include a first damper configured to be disposed about a hub assembly of the bicycle wheel assembly. The first damper is configured to apply a first damping force against a spoke segment of at least one spoke of a plurality of spokes of the bicycle wheel assembly. The spoke segment is spaced apart from a spoke attachment member.

A method of manufacturing a hollow coil spring which is made of a hollow wire in which a terminal sealed portion is formed on an end portion of the wire. The terminal sealed portion has a rotationally symmetric shape in which an axis passing through the center of the wire is the symmetric axis. The hollow coil spring includes an end wall portion, and an end face arc-shaped curved surface. The end wall portion includes an end face perpendicular to the axis. A distal-end-center closure portion is formed on the axis at the center of the end wall portion. A spring seat includes a base member and a sheet member. An end turn portion of the hollow coil spring is in contact with the sheet member. The end face of the end turn portion is opposed to a stopper wall of the spring seat.
