A front axle of a vehicle, configured for reducing vibration, which is connected to a knuckle having a front wheel disposed thereon through a king pin, in which a gap may be formed between the knuckle and the king pin passing through the front axle and the knuckle, and filled with lubricant oil, and at least one of the king pin and the knuckle may include a plurality of rollers disposed therein, the rollers having an axis parallel to an axial direction of the king pin while circumferences of the rollers are partially buried in at least one of the king pin and the knuckle.

Embodiments generally relate to hinge mechanisms. Many of the hinge mechanism embodiments may be used in foldable furniture. The foldable furniture may be a foldable seat or table. The hinge mechanism may include a central cylinder with a body defining a hinge axis. The central cylinder may have rotate channel(s) transverse to the hinge axis and locking channels extending axially from the rotate channel(s). Collar(s) may couple with the central cylinder and may include pin(s) that protrude inwardly into the rotate channel(s) and locking channel(s) of the central cylinder. In some embodiments, an intermediate cylinder may be disposed between the central cylinder and the collar(s). The intermediate cylinder may have slots corresponding to the rotate channel(s) of the central cylinder. When pin(s) and locking channel(s) are aligned, the central lock cylinder may move axially to lock the collars in a desired angular position (e.g., a deployed or folded configuration).

Bearing structure of a pedal device, wherein a support member having a cylindrical outer peripheral surface is fixedly attached to a pedal bracket to be substantially horizontal, a boss of a pivot member radially outside the support member via a pair of flanged bushings each made of resin and having a flange portion at one end of a cylindrical portion so the boss turns about an axis, both axial ends of the flanged bushing cylindrical portion closely contact the boss inner peripheral surface; the flanged bushing cylindrical portion have, in intermediate portion, in an axial direction, a narrow portion having both inner and outer peripheral surfaces reduced in diameter so the narrow portion is curved inward in radial direction; the narrow portion smallest inside diameter being smaller than the support member outside diameter having interference; at least the narrow portion smallest diameter portion of elastically closely contact the support member outer peripheral surface.

Exemplary embodiments provide a rotary misalignment-compensation bushing connection system that may be used in large-scale operations where several components are mounted in alignment on a single pin. For example, the misalignment-compensation system may be used in preloaded connection of a male lug rotatably mounted between a first lug and a second lug, on heavy equipment, for example, oil field exploration and production equipment. The misalignment-compensation system includes tapered cone bushings and surrounding counter-tapered cup bushings that expand in diameter and align the connection system as it is torqued together assembling the components to the pin.

A bearing assembly includes a cylindrical configuration with a radial direction, a circumferential direction and defining a bearing assembly longitudinal axis, a first axial end, and a second axial end, an inner radial race, an outer radial race, a bearing member configured to be disposed radially between the inner radial race and the outer radial race, and a retaining ring configured to engage the inner radial race and the outer radial race, the retaining ring being configured to limit longitudinal movement of the inner radial race relative to the outer radial race once assembled.

Biaxial hinge compatible with thinner terminal device capable of avoiding any hindrance to the use of various plugs, the biaxial hinge having an attaching part attached to a first casing of the terminal device, wherein the attaching part has an attaching plate section and a bearing section, a first hinge shaft, a second hinge shaft, wherein the second hinge shaft is in parallel to the first hinge shaft and rotatable, a synchronous rotation generator for rotating the first and the second hinge shafts in a synchronized manner in a direction different from each other, a friction torque generator provided on the second hinge shaft for generating a friction torque to rotation of both hinge shafts, and a rotational force generator provided on the second hinge shaft as well.
