A vehicle rim including outboard and inboard bead seats and an annular well flank connected to the outboard bead seat and extending radially inwardly and towards the inboard side of the rim. A well base is connected to the well flank, wherein the well base defines a flat profile, and wherein the well base defines the inner-most radial dimension of the rim. A transition portion is defined between the well flank and the inboard bead seat. The transition portion has a circumferential corrugated profile having a circumferentially concave-shaped outboard groove connected to the well base at a first tangency point, a circumferentially convex-shaped ridge directly connected to the outboard groove at a second tangency point, and a circumferentially concave-shaped inboard groove directly connected to the ridge at a third tangency point. The inboard groove is connected to the inboard bead seat at a fourth tangency point.

The invention is directed to a method for producing a rim (2) comprising at least one three-dimensionally shaped layer of reinforcing fibers (26). In a first step a forming tool (25) is provided which comprises a three-dimensionally shaped outer contour. In a subsequent step a band of reinforcing fibers (26) is wound onto the forming tool (25) such that the reinforcing fibers follow the outer contour of the forming tool (25) and are arranged in at least one of reinforcing fibers. A draping device (27) is provided by which the band of reinforcing fibers (26) is preformed before the band of reinforcing fibers (26) is wound onto the forming tool (25).

A process for manufacturing a light-alloy hybrid wheel implements the following separate operation phases: making a flange with an internal profile capable of constituting a tire bead seat; making a rim with, on one side, an outer profile capable of constituting a tire bead seat and, on the other side, a circular flank for assembly with a part of the flange; assembling the flange with the rim, at the seat of said flange and the circular flank of the rim. The rim is made according to the following consecutive operations: an operation of manufacturing a circular flank; then an operation of expanding said circular flank to the size of the final rim in a single step; then an operation of cold or hot flospinning of said circular flank so as to obtain the rim in the final shape and profile thereof, comprising a shoulder only on the side that will not be welded to the flange.

The invention relates to a device and method for detecting the wheel center depth of an aluminum wheel cast blank, the device includes a roller way tray, a position sensor, a frame, a CCD camera, a programmable controller and a laser distance measurement sensor, an upper servo-cylinder, a motor support, a servo-motor and a lower servo-cylinder. The invention has the following advantages: the method for automatically detecting and identifying the wheel center depth of an aluminum wheel cast blank is utilized for the identification and classification of wheel cast blanks, so as to reduce the influence of large casting dimension tolerance on the machining dimension tolerance, increase the acceptability rate of products from the automatic machining unit, ensure that the production line automatically runs with high quality and quantity and also reduce the labor intensity of operators.

The present invention provides an improved inner-supporting-type online roundness correcting device for a semifinished wheel, which comprises a machine frame, hydraulic cylinders, guide rails, servo motors and correcting wheels. When a bulge of the wheel is met, angles of left correcting wheels II are adjusted through a left servo motor, the left correcting wheels II are kept to be in contact with an inner rim of the wheel all the time and remain stationary in the position, and then, a left hydraulic cylinder enables a left correcting wheel Ito press the bulge of the wheel, so as to recover the roundness of the bulge; and when a depression of the wheel is met, right correcting wheels I are kept to be in contact with an outer rim of the wheel all the time and remain stationary in the position through a right hydraulic cylinder, the angle of a right correcting wheel II is adjusted through a right servo motor, and compressing hydraulic cylinders enable the right correcting wheel II to press the depression of the wheel, so as to recover the roundness of the depression.

The present invention relates to an online roundness correcting device for a semifinished wheel, which consists of a jacking and rotating system, a left correcting system, a right correcting system and a central locating system. According to the online roundness correcting device provided by the present invention, in service, an online roundness correcting function for the semifinished wheel can be achieved, and the corrected wheel has good roundness and cylindricity, so that not only can the labor intensity for workers be lowered, but also the online roundness correcting device has the characteristics of high degree of automation, advanced process, simple structure and safe and stable performance.

Hydro forming method for constructing a piece of vehicle wheel rims. The whole process will be implemented in seven stages. As the first station of raw sheet by the form Stretch a piece of cylindrical internal diameter sized the smallest inner diameter and the 1.6 height rim and this diameter is larger than the outer rim diameter. Secondly outer rim diameter cylindrical piece is the desired size trim. In the third and main stage action takes place hydro forming cylindrical piece by piece into a specific form of work (work piece) with no Punches final form and elasticity are required.
