The present invention relates to a vehicle wheel, in particular for motor vehicles, with a rim ring having an opening, with a basic support at least partially arranged in the opening in the rim ring, wherein the basic support has a connecting region with receptacles for connecting means for connecting the vehicle wheel to the vehicle, and with a covering shell for at least partially covering the basic support. The problem of indicating a vehicle wheel which, despite a low weight and sufficient rigidity with high design flexibility, has a secure connection and no loss of bracing force, is solved in that the covering shell is designed in such a manner that the basic support is free from the covering shell at least in the region of the receptacles. Furthermore, the present invention relates to a method for producing a vehicle wheel.

A mounting structure 10 having improved stiffness characteristics. The mounting structure 10 includes a pillar 14 which forms a portion of a vehicle body 12 and which operatively supports a vehicle door which is selectively attached to the pillar 14 by hinges 16. The structure 10 includes a pair of "closed-loop" beads which are formed around hinges 16, and which increase the stiffness characteristics of the pillar 14 and of the vehicle door.

A thermal bend actuator (6) is provided with a group of upper elongate actuator arms (23, 25, 26) and a group of lower elongate actuator arms (27, 28) which are non planar, so increasing the stiffness of the arms. The arms (23, 25, 26, 27, 28) may be spaced transversely of each other and do not overly each other in plan view, so enabling all arms to be formed by depositing a single layer of arm forming material.

A motor-vehicle wheel structure comprises a wheel rim and a wheel disk having a circumferential border bent and welded within the wheel rim, and a central portion bearing a circumferential series of holes for engagement of bolts for fixing the wheel to the wheel support. The central portion is radiused to the circumferential border of the disk by means of an intermediate annular portion having in cross section an arched configuration projecting outwards. The intermediate annular portion has a plurality of embossed portions projecting outwards, configured in such a way as to define a plurality of spokes set at the same angular distance apart from one another.

The invention relates to a space-controlled five degree of freedom twelve-rod welding robot mechanism which comprises a plane two degree of freedom controlled mechanism branch chain, three gesture regulating branch chains, a movable platform with a flange plate, and a stand, wherein the back of the movable platform is respectively connected with the four branch chains through a first spherical pair, a third spherical pair, a fifth spherical pair and a seventh spherical pair; and the flange plate on the movable platform is used for installing equipment, such as a welding gun or welding tongs and the like. All servo motors are arranged on the stand, and a lever can be made into a light rod, thus the robot has small motion inertia and good dynamic property, and can better satisfy the requirement for high-speed accurate welding.

Provided is a collaborative energy dissipation anti-buckling supporting construction member with a major earthquake protection function. An outer arresting cylinder encloses an energy dissipation inner core plate from the outer portion, an end portion connecting plate and an outer arresting cylinder outer connecting plate are arranged at two ends of the outer arresting cylinder, one end of the outer arresting cylinder is fixed on the end portion connecting plate, the other end is free from being connected, one end of the energy dissipation inner core plate is fixed on the end portion connecting plate, the other end of the energy dissipation inner core plate is connected with the end portion connecting plate in a welded mode, the end portion connecting plate is fixed on the outer arresting cylinder outer connecting plate, the energy dissipation inner core plate is connected with a friction automatic restoration device through an outer arresting cylinder outer connecting plate of a welding end, and thus series connection between a traditional anti-buckling supporting construction member and the friction automatically reset device is achieved to form the novel anti-buckling supporting construction member which has an automatic restoration characteristic and can achieve friction and cross-section yield collaborative energy consumption in an over-expected earthquake even a mega-earthquake. The problems of safety, continuous energy dissipation ability and restoration after the earthquake of the traditional anti-buckling supporting construction member in the over-expected earthquake even the mega-earthquake are resolved.

A motor-vehicle wheel structure comprises a wheel rim and a wheel disk having a circumferential border bent and welded within the rim, and a central portion bearing a circumferential series of holes for engagement of bolts for fixing the wheel to the wheel support. The central portion is connected to the circumferential border of the disk by an intermediate annular portion having in cross section an arched configuration projecting outwards. Welded on the outer face of the wheel disk is an auxiliary disk having a substantially plane conformation, the outer border of which is welded to the main disk substantially in a position corresponding to the apex of the aforesaid projecting annular portion. The auxiliary disk integrates tubular columns that project from the inner face of the auxiliary disk and have their ends welded to the central portion of the main disk so that they are co-axial to the holes for the fixing bolts.
