A joint structure includes a first member configured to be connected rotatably to a mating member, and a second member configured to be connected rotatably to an actuator for driving the mating member. Each of the first and second members has one or more ridge portions that extend circumferentially along an outer peripheral surface. The joint structure further includes a core shaft connecting the first member and the second member, and a covering member provided tightly thereon to cover the core shaft, the one or more ridge portions of the first member, and the one or more ridge portions of the second member.

A tie-rod with a swivel tie-rod end includes a tie-rod central rod and a first tie-rod end including a swivel joint. The first tie-rod end is connected to the tie-rod central rod by the swivel joint. The swivel joint is operable to enable rotation of the first tie-rod end with respect to the tie-rod central rod while maintaining a common longitudinal axis between the first tie-rod end and the tie-rod central rod. The tie-rod further includes a second tie-rod end connected to the tie-rod central rod.

The present invention achieves a high mechanical load capacity of a rod end by means of a component loop that passes around a bearing, where the component may be made of continuous-fiber reinforced composite material with thermoplastic matrix and where the continuous-fiber reinforced composite material with thermoplastic matrix may extend into a threaded stem of the rod end, and the component made of continuous-fiber reinforced composite material with thermoplastic matrix may be enclosed by short-fiber reinforced, long-fiber reinforced, or unreinforced thermoplastic. The threaded stem can be implemented with an external or an internal thread.

A device for fitting two components together by a clevis is improved by a seal including a deformable ring subjected to axial compression between one of the cheeks and a mobile washer which is brought closer to the cheek when a bolt passing through the clevis is tightened. This axial compression causes the rod to be clamped by the seal, eliminating all play and giving the assembly good cohesion while at the same time eliminating the transmission of vibration and noise.

transmission device, particularly for an engine with variable compression rate and/or variable displacement, includes, in a cylinder housing: a combustion piston, capable of moving in a combustion cylinder of the engine and secured to a transmission member; a gear engaging with a first rack of the transmission member and providing transmission of the movement between the combustion piston and a crankshaft of the engine; a connecting rod engaging, at a first end, with the gear and, at a second end, with the crankshaft; and a control member engaging with the gear and secured to a control piston. The combustion piston and the transmission member are slidably linked with the cylinder housing in a main direction.

A leading-edge steering system is provided for a front suspension of an off-road vehicle. The leading-edge steering system is comprised of a spindle assembly that supports a drive axle assembly to conduct torque from a transaxle to a front wheel. A first rod-end joint pivotally couples an upper suspension arm and the spindle assembly, and a second rod-end joint pivotally couples a lower suspension arm and the spindle assembly. A steering rod-end joint pivotally couples a first end of a steering rod with a leading-edge portion of the spindle assembly. A steering gear is coupled with a second end of the steering rod and configured to move the steering rod, such that the spindle assembly rotates with respect to the upper and lower suspension arms. The leading-edge portion is configured to exert primarily tensile forces on the steering rod during travel over rough terrain.

The method includes producing an initial preform on a mandrel by filament winding without generating shrinking, cutting the initial preform to the correct length, placing the assembly provided beforehand with internal drainage device and pressurization device into a female mold, and bringing the preform assembly to a softening temperature and pressurizing the assembly at both ends until it is deformed by a diametrical increase in its dimensions. The method further includes bringing the impregnation resin to polymerization temperature and pressure in order to allow the workpiece to consolidate, its external shape becoming consistent with the internal shape of the mold, opening the mold and removing the workpiece from the mold, and machining the final shapes of the composite workpiece.

A joining structure according to one embodiment of the present invention includes a first member and a second member, the first member having a hole extending along an axis direction, the second member including a shaft member, the shaft member being formed of a fiber-containing composite material and having a shape to fit in the hole, the second member being joined to the first member via the shaft member so that movement thereof in the axis direction is restricted.
