The present disclosure relates to a steering stabilizer for a vehicle. The stabilizer has a damper having a housing, a piston rod extending telescopically from the housing, and a coil spring disposed over the damper. An inner adapter assembly secures a first end of the damper to one of a wheel component or a body component of the vehicle. An outer adapter assembly is coupled to a distal end of the piston rod and couples to the other one of the wheel or body component. A one-piece spring seat is fixedly coupled to the housing. The coil spring is supported at a first end by the spring seat and at a second end by the outer adapter assembly. The spring seat enables the single coil spring to return the steering stabilizer to a central position regardless of whether the single coil spring is under tension or compression.

Disclosed is a hydraulic bushing and a rail vehicle. The hydraulic bushing comprises: a core shaft; a sleeve mounted on the core shaft, wherein a first rubber body is filled in a space formed between the core shaft and the sleeve, and a groove is provided on an outer surface of the sleeve; and an outer housing, which is mounted on the sleeve through press fit. Two liquid chambers for accommodating liquids are provided diametrically opposite to each other on the first rubber body, and the groove and the outer housing together define a flow channel, through which the two liquid chambers communicate with each other. Use of the hydraulic bushing on the rail vehicle not only can assure stable operation of the vehicle in a straight running state thereof, but also can reduce abrasion of a wheel and a rail in a curve running state.

A power strut includes anisotropic damping device that provides different frictional torque on a rotatable member in response to rotation in opposite rotational directions. The anisotropic damping device includes a shell, the rotatable member, and a torsion spring. The shell includes a through hole, and the rotatable member extends through the through hole and is rotatably connected to the shell. The torsion spring is sleeved on the rotatable member and is in interference fit with the rotatable member, and the torsion spring is provided with a first leg fixedly connected to the shell. The rotatable member may include a shaft sleeve fixed to a rotating shaft, with the torsion spring in interference fit with the shaft sleeve.

A cable car carriage for transporting goods or passengers has two opposing spaced-apart crawlers. Each of the crawlers has a crawler chain composed of juxtaposed chain links. A support cable can be inserted between the opposing crawlers on the opposing chain links of the crawler chains. A pressing mechanism connects the crawlers with one another, and is designed to adjust the distance between the crawlers as well as the pressing force of the two crawlers relative to each other and/or the pressing force of the two crawlers against the support cable. The crawler chains are driven in a circulating movement by a drive via a crawler running gear, thus moving the cable car carriage along the support cable. A cable crane, a passenger gondola, a cable saddle, and a transport assembly employing the cable car carriage are also disclosed.

A brake operating device to improve a brake feeling by a simple structure without a hydraulic source or an electric power source. A first reaction force establishing mechanism as an elastic member establishes the reaction force against the pedal force applied to the brake pedal. A second reaction force establishing mechanism increases the reaction force when depressing the brake pedal. The first reaction force establishing mechanism and the second reaction force establishing mechanism are arranged coaxially in series.

An object of the present invention is to provide a sway amount estimation system that can suppress a reduction in user convenience that would occur if the operation method is switched more than necessary. A sway amount estimation system (300) includes a sensing unit (78), a judgment unit (80), and an estimation unit (79). The estimation unit (79) calculates an estimated value of the amount of sway of an elevator rope due to vibration caused by building sway based on the sway sensed by the sensing unit (78) and an estimation model incorporating the effect of the displacement amplification of the displacement amplifier (7). The judgment unit (80) judges if the estimated value calculated by the estimation unit (79) is greater than a threshold for switching the operation method for the elevator apparatus (11).

A suspension system includes a first suspension member movable relative to a second suspension member, a fluid reservoir having a volume, the volume variable in response to a relative movement between the first and second suspension members, and a fluid flow circuit having a first end in fluidic communication with the fluid reservoir and a second end in fluidic communication with an isolated suspension location, the fluid flow circuit comprising a first valve, a second valve and a third valve, wherein said first and third valves are in parallel with each other and the second valve is in series with each of the first and third valves.

An object of the present invention is to provide a vibration damping device including an instability preventing means, for efficiently suppressing amplification of vibration of a long structure, which is mechanically flexible, due to a resonance phenomenon. A vibration damping device (100) for reducing vibration of a long structure (1) includes a displacement amplifier (7) and limiting members (8). The displacement amplifier (7) is arranged along a given position in the longitudinal direction of the structure (1). The displacement amplifier (7) amplifies a displacement of the structure (1). The limiting members (8) control displacement amplification performed by the displacement amplifier (7) such that the displacement of the structure (1) amplified by the displacement amplifier (7) does not become greater than a first displacement, the first displacement being a displacement of the structure (1) by which the structure (1) is not allowed to return to the equilibrium position of the vibration.

A suspension apparatus includes a first tube and a second tube that are telescopic and that are disposed on a vehicle body side and on a wheel side, respectively; a cylinder that is provided in the first tube; a rod that is provided in the second tube; a piston that is provided on the rod, slidingly contacts with an inner circumferential surface of the cylinder, and forms a first gas chamber on a side of the first tube; a coil spring configured to urge the first tube and the second tube in an extension direction; and a spring receiving member that is disposed at a position on a second tube side from a movable region of the piston, the coil spring being disposed between the spring receiving member and the second tube.

According to certain embodiments, a vibration-isolating case comprises a resilient, plastic-composite walled case and vibration-damping footing located at the bottom side of the case. Each vibration-damping footing comprises a mounting plate, cushions, and a damping system. The mounting plate has a flat surface and side surfaces extending from the flat surface to form a channel-shaped structure. The flat surface is positioned proximate a bottom outer surface of the case and couples to at least one brace within the case. The cushions are positioned within the channel-shaped structure such that the side surfaces of the mounting plate protect at least a top portion of each cushion. The damping system is positioned between the cushions and comprises a tray containing a quantity of inelastic particulate. A mechanical path exists between the vibration-damping footing and a platform mounted within the case.
