Abstract: An automatic assembling system has a component tray, an assembly table, a mechanical arm and pressing tool. The mechanical arm includes a rotary disc and a plurality of gripping devices mounted on the rotary disc, wherein the rotary disc is configured to rotate about an axis such that one of the plurality of gripping devices is aligned with a corresponding component disposed on the component tray and grips the corresponding component. The pressing tool is also mounted on the rotary disc and is configured to press and/or adjust an assembled component on the assembly table.

Abstract: A tire mounting device is constructed from a first working mechanism and a second working mechanism that are separated from each other. The first working mechanism is provided with a tire holding means for holding a tire and with a temporary tightening means for temporarily tightening nuts onto hub bolts to which the tire is mounted. The second working mechanism is provided with a final tightening means for finally tightening the temporarily tightened nuts.

Abstract: Systems for removing a tire from a rim are shown and described. In one embodiment, the system comprises a substantially flat base. A centerpiece is configured to attach to the base. A primary lever having a tire-interface portion at one end, a handle at the opposite end, and a centerpiece-attachment in between the tire-interface the said handle is also a component of the system. The primary lever is configured to attach to the centerpiece in a manner that allows the primary lever to rotate relative to the centerpiece.

Abstract: A hollow-cylindrical portion (26) inserted in a hollow-cylindrical portion (16) of one rim section (12) is provided on the other rim section (13). To form a split rim (11), part (head portion) of the inner hollow-cylindrical portion (26) overlaid on the outer hollow-cylindrical portion (16) is radially outwardly expanded by being elastically deformed by a tapered surface (39) of a piston (38) such that the inner and outer hollow-cylindrical portions (16, 26) are in close contact with each other. As a result, relative positions of the rim sections (12, 13) are strictly defined, and this enables high assembling accuracy, particularly coaxiality with a high level, to be achieved. A fine fitted to the split rim (11) can be inspected with high accuracy.

Abstract: A split rim for pneumatic tire includes a disk part having a seat portion allowing a corresponding tire bead part to be seated at the radial outer end. First and second pieces are connected to the disk part and have cylindrical parts coaxial with the disk parts. The cylindrical part of the second piece can be inserted into the cylindrical part of the first piece. The cylindrical parts of the first and second pieces overlap with each other in the inserted state and are connected to each other by a fastening mechanism. The fastening mechanism includes a group of claws formed on the inner circumference of the first piece cylindrical part and a group of claws formed on the outer circumference of the second piece cylindrical part.

Abstract: A method of fitting a tire P and a removable tread support S on a one-piece wheel rim J, rim comprising a first rim seat, inclined outwards, and the tire P comprises a first bead and a second bead to be mounted respectively on the first and second rim seats, in which, before completion of fitting the support S on a rim bearing surface of the rim, the first bead is gripped at a given point and is moved radially outwards to radially separate this point on the first bead from the support S. The fitting of the support S on the rim bearing surface continues and the bead is released after completion of the fitting of the support S.

Abstract: A bead breaker device (1) having an arm (2) able to slide horizontally along a sliding axis (X—X), in a pipe (3) supported so that it can slide vertically on a post (4) projecting cantilevered from a base; an orientable bead breaker tool (10) associated with an end of said arm (2) and suitable for breaking the bead of a tire of a wheel removably fixed onto rotary support and locking apparatus of the rim; an actuating device (14, 15, 17) suitable for orienting said tool (10) between a first thrusting configuration and a second penetration configuration, said actuating device (14, 15, 17) including a thrusting body (14) and an elastic element (17) cooperating with said tool (10), said thrusting body (14) being able to be actuated between a first extension position against the action of said elastic element (17) and a second release position in which the force exerted by said elastic element (17) prevails.
