The present invention relates to a multidirectional wheel, wherein the wheel has a wheel body rotatable about a wheel axle and having two half-shells and has a plurality of rotating bodies which are located at the outer periphery of the wheel body and via which the wheel can roll off, wherein at least one half-shell, and preferably both half-shells, has/have mounts in which end regions of the axles of the rotating bodies are received or which project into end regions of the axles of the rotating bodies, wherein the mounts of the half-shells are configured as continuously converging.

The present invention provides a universal wheel spraying protection device, which is composed of a chassis, springs, a cone shaft, a tray, sliding blocks and composite tensioning sleeves. When the universal wheel spraying protection device is in use, a wheel is placed on a conical surface of an upper end of the tray, supporting springs are compressed by self weight of the wheel, and the tray is pressed down under the action of guiding columns and guiding sleeves; meanwhile, each sliding block drives the corresponding composite tensioning sleeve to move outwards under the action of the cone shaft; after a central hole is tensioned, the sliding blocks stops radial movement, and the tray also stops axial movement; and at this time, the central hole is protected by the composite tensioning sleeves, and a flange face is protected by the conical surface of the tray.

Provided is a method of manufacturing a wheel bearing apparatus including an outer ring, a rolling element, a hub spindle, and an inner ring member. The hub spindle is disposed inward of the outer ring in a radial direction via the rolling element. The inner ring member fitted on the hub spindle and is secured by a clinched portion. The clinched portion is formed by clinching a spindle end portion of the hub spindle outward in the radial direction. The method includes: plating a predetermined area including the spindle end portion of the hub spindle; removing a plating of the spindle end portion of the predetermined area; and clinching the spindle end portion to form the clinched portion after removing the plating.

A vehicle wheel decoration method includes a setting step of detachably holding a wheel body in the holding member such that the wheel design face faces the discharge nozzle, and a decoration step of forming a decorative layer on the wheel design face by discharging paint from a discharge opening of the discharge nozzle toward the wheel design face while relatively moving the discharge nozzle in two directions with respect to the wheel design face of the wheel body held in the holding member, and, in the decoration step, the wheel body is relatively inclined in a direction which crosses moving directions toward the two directions by a relative move of one of the discharge nozzle and the holding member or relative moves of both of the discharge nozzle and the holding member, and the discharge opening of the discharge nozzle is relatively moved in the two directions.

The invention relates to a roll-up traction mat (10) for a vehicle (V) having at least one wheel (R1), said traction mat comprising a main track portion (12), and a track starter tab (20) that is fastened to one of the ends of the main track portion (12) by a hinge-forming connection portion (22) arranged to lower the track starter tab relative to the main track portion, by means of which the track starter tab can be positioned at the bottom of a rut (O) in which said wheel of the vehicle is stuck. The track starter tab comprising a plurality of transverse stiffener elements and a top face provided with studs. The track starter tab and the main track portion are constituted by at least one textile layer covered in a polymer layer.

Disclosed is a vehicle wheel having a wheel rim and a wheel disc connected to an inner side of the wheel rim. The wheel disc is connected to the wheel rim by a connecting element which is guided through a through-hole of the rim base and inserted in the wheel disc. The through-hole is arranged in the tire seat of the rim base and the connecting element is joined substantially in the direction of the radial extension of the wheel disc which is associated to the tire seat on the inner side of the rim. In the method for producing the wheel the connection between wheel rim and wheel disc is produced in the region of the tire seat of the rim base, and, after the insertion of the connecting element into the wheel disc, a portion of the connecting element protruding the contour of the outer side of the rim of the tire seat is shaped so that the connecting element conforms to the contour of the outer side of the rim of the tire seat.

This invention is related to a lightweight process of manufacturing a bicycle's rim and a rim structure manufactured thereby. A rim frame comprising an inner frame, a cladding part, and a support part between the inner frame and the cladding part. The inner frame and the support part are milled to form plural through holes uniformly distributed thereon. The areas occupied by the through holes is 35% to 85% of a total surface of the inner frame and the support part. Moreover, a proper distance is formed between the adjacent through holes in the process, and a carbon fiber layer covers the outer surface of the rim frame. Therefore, the weight of the bicycle's rim is decreased, and the carbon fiber layer can stably attach on the rim frame to increase the structural strength of the rim.
