A bicycle hub shaft includes a first shaft section made of a first material and inserted into a sprocket seat; and a second shaft section made of a second material. The strength of the first material is stronger than that of the second material. The first shaft section has one end connected to one end of the second shaft section. The bicycle hub shaft is formed by the first and second shaft sections, instead of being integrally formed. Besides, the strength of the first shaft section is stronger than the second shaft section, so that the first shaft section inserted in the sprocket seat has a higher structural strength, thus improving the strength of the bicycle hub shaft and the load capacity of the sprocket seat as well.

A coupled torsion beam axle for buckling induction may include a torsion beam, a cross section of which varies laterally, a right axle coupler and a left axle coupler being respectively formed at both end portions of the torsion beam, the torsion beam being provided with a buckling induction member configured to induce buckling deformation by an external load applied to each of the right and left axle couplers.

An air reservoir for a steering axle is mounted on a trailer, the steering axle comprising a pair of rotation pivoting wheel assemblies. Each wheel assembly has a rotation plate and a steering arm connected thereto. A rod pivotally connects the steering arms, each wheel assembly being rotatably connected to either end of the axle. An air stabilizer assembly is mounted on the axle and is connected to the rod, the air stabilizer assembly having an inflatable damper assembly thereon. An air supply is fluidly connected to an air inlet on the axle, the air inlet being fluidly connected to the damper assembly. The air stabilizer assembly dampens pivotal movement of the wheel assemblies when compressed air from the air reservoir fills the damper assembly. The air stabilizer assembly allows the wheel assemblies to rotate more freely when pressure of the compressed air within the damper assembly is reduced.

An axle and wheel end assembly includes a tubular axle housing with an annular end surface. The axle and wheel end assembly also includes a spindle with an annular end surface welded to the annular end surface of the tubular axle housing at an attachment periphery. The axle and wheel end assembly further includes reinforcing structure fixed to the tubular axle housing and spindle. The reinforcing structure is located to encompass at least a portion of the attachment periphery.

A split offset axle joins a front cycle wheel to a first and a second fork of a cycle. The axle has two rigid structures joined together with a fastener to form a singular axle. The axle has a cylindrical first end, a cylindrical second end and a cylindrical offset center section. The center section locates and supports a cycle wheel hub. The first and the second ends are housed in a pinchable split axle housing of the first and the second fork, respectively. Rotation of the axle adjusts the center section axis to a plurality of positions relative to the forks. The center section is adjusted to a desired position, thereby adjusting the cycle's steering and handling characteristics, the desired position is secured with pinched split axle housings. The pinched split axle housings rotationally and rigidly secure the respective axle ends.

An EZ SPEEDY AXLE KIT for increasing the mobility of foldable sawhorse stands while allowing the tires used to be customizable. The invention consists of an axle that connects all of the pieces together. It is mounted with two fasteners that pass through the axle. Two spindles thread into the axle to allow them to be removable. Two objects with threaded apertures lock the spindles in place as well as provide the necessary preload to the bearing races of any tire used. The invention allows for any size spindle and tires to be used as long as the spindle can thread into the axle.
