An omni-directional wheel for a pool vacuum head includes a first frame and a second substantially identical frame, each frame having a hub rotating around a common axis, lower supports extending radially from the hub, risers extending from the hub along the common axis, and upper supports individually coupled to the risers, the upper supports extending radially from the common axis. Rollers coupled to the first frame and the second frame, are radially spaced from the common axis on each frame. The rollers rotate normal to the common axis to impart omni-directional movement. When the first frame and the second frame are interlocked, the risers on the first frame engage the hub on the second frame, and the lower supports on the first frame engaging the upper supports on the second frame, maintaining the rollers in a staggered arrangement around the wheel.

A multi-lobed wheel adapted to be mounted to an agricultural platform for traversal of an agricultural field generally traverse to adjacent rows of planted crops without crushing the individual plants. The multi-lobed wheel having a wheel hub including a central axis on which the multi-lobed wheel is configured to rotate and a plurality of spaced apart lobes defining an outer perimeter configured to make ground engaging contact with the agricultural field, the outer perimeter including structure presenting a plurality of gaps between the plurality of spaced apart lobes, the gaps shaped and sized to provide sufficient clearance for individual plants within a planted crop row so as to enable the multi-lobed wheel to pass over a planted crop row without crushing the individual plants therein.

Disclosed herein is a wheel, in particular for vehicles, such as motor vehicles, with a rim ring having an opening defined there through, and with a main support at least partially arranged in the opening in the rim ring. The wheel, despite having a low weight, provides adequate rigidity and strength and can be produced in a simple manner, while maintaining design flexibility. The main support of the wheel has a plurality of spokes, and a plurality of covering parts for at least partially covering the spokes, wherein the main support and the covering parts support the rim ring.

A method for manufacturing a vehicle wheel includes: a casting process of manufacturing the wheel in a one-piece body having a forming end and a temporary flange protruding at inner and outer sides of the wheel, respectively, wherein the one-piece body further includes a resonance chamber forming groove; a primary shape machining process of forming a stepped part at an outer circumferential side of the resonance chamber forming groove; a flow forming process of bending the forming end to be seated on the stepped part; a friction stir welding process of integrally bonding a portion where the forming end and the stepped part are in close contact with each other; a fine machining process of removing the temporary flange;

and a sound-absorbing hole machining process of forming a sound-absorbing hole for communicating between the resonance chamber and an interior space of a tire in the forming end.

An adaptive rim has a disk wheel center and a central wheel flange, which are arranged concentrically to one another and are connected to one another. Between the disk wheel center and the wheel flange a detachable connection is formed, wherein the disk wheel center and the wheel flange can be separated from one another after the connection is released. Thus, the wheel flange in the case that it is incompatible with a wheel suspension, can easily be exchanged for another compatible wheel flange. Accordingly, a rim system has at least one rim and a first wheel flange detachably connected to said disk wheel center, and at least one second wheel flange, in which, after the disk wheel center and the first wheel flange have been separated from one another, the second wheel flange instead of the first wheel flange can be detachably connected to the disk wheel center.

A jig for mounting a component on a structure is disclosed. The jig includes a frame having a base defining an elongated channel and adapted to be disposed substantially parallel to a surface. The jig also includes a support assembly for supporting the component to facilitate the mounting of the component on the structure. The support assembly extends vertically through the elongated channel and adapted to slide relative to the base along a length of the elongated channel.

A holding device includes a pair of holding members positioned to be spaced apart from each other in a first direction, and a moving part that moves at least one of the pair of holding members to change a distance between the pair of holding members in the first direction. Each of the holding members is formed with a support face that supports the flange of the wheel, and an engaging portion that is located on an end portion side that is on an opposite side from the other holding member, and is able to engage with the flange of the wheel supported by the support face, from the radially outer side of the wheel. The installation space for a tire mounted on a wheel on the radially outer side of a flange of the wheel is prevented from varying due to the magnitude of the diameter of the wheel.

A split-type hard front axle includes an axle housing; an axle tube connected to the axle housing; an inner-C-forging connected to the axle tube and configured for connecting with a kingpin knuckle; and a connection structure cooperated with the inner-C-forgoing for detachably fixing the inner-C-forging on the axle tube. The axle tube includes a first angle adjustment structure. The inner-C-forging includes a second angle adjustment structure. A portion of the inner-C-forging is capable of deforming under a force exerted by the connection structure, to fix the inner-C-forging on the axle tube. The first angle adjustment structure is capable of cooperating with different portions of the second angle adjustment structure to make the inner-C-forging have different installation angles on the axle tube, and a caster to pinion angle is being different at inner-C-forging's different installation angles. A vehicle is also provided.
