A wheel disc includes a wheel mounting portion defining a wheel axis, a plurality of spokes radially extending from the wheel mounting portion, and a rim junction on at least one spoke of the plurality of spokes. The rim junction is at an end of the at least one spoke opposite the wheel mounting portion. A first portion of the rim junction extends in an axial direction. Second and third portions of the rim junction extend in a circumferential direction. The axial direction is parallel to the wheel axis and the circumferential direction is in a plane perpendicular to the wheel axis.

A mounting portion of a disc includes a flat plate portion having a pressing surface to be pressed against a hub of an axle, and a plurality of nut support portions protruding from the flat plate portion to a side opposite to the pressing surface in an axial direction of the disc, and having an annular shape as viewed from the axial direction. A bolt hole is provided to penetrate the nut support portion in the axial direction. The nut support portion includes a bulging portion curving to bulge outward in a radial direction of the nut support portion, and a protruding portion disposed adjacent to the bulging portion in a circumferential direction of the nut support portion, and protruding inward in the radial direction of the nut support portion with respect to the bulging portion.

A wheel includes a rim and a wheel center interconnected to the rim. The wheel center includes at least one spoke extending from a wheel hub to the rim in a radial direction. The rim includes per the at least one spoke a first contact area and the at least one spoke includes at its outer end a second contact area which in a mounted position is aligned to the first contact area. The at least one spoke includes at least one hollow space extending in the radial direction of the spoke.

This application describes the creation of a wheel disc for a trailer using a three-hit manufacturing process.

The invention relates to a wheel, especially for motor vehicles, comprising a wheel rim and a wheel disc, the wheel rim having a rim base made of fiber composite material. The invention is characterized in that the wheel disc (3, 11, 20, 29, 40) can be indirectly connected to the wheel rim (1), in particular the rim base (2), by means of a connecting element (5, 14, 22, 31, 35, 42) which is designed and associated with the rim base (2) in such a way that the connected wheel disc (3, 11, 20, 29, 40) is not in contact with the rim base (2).

This non-pneumatic tire is provided with a tread ring, a wheel which is arranged radially inside of the tread ring, and spokes which are interposed between the tread ring and the wheel. Further, the wheel has a disc part to which the vehicle shaft is linked, and a rim part which is connected on the inner peripheral side to the disc part and is joined on the outer peripheral side to the spokes. In this configuration, the average thickness (T1) of the disc part is set to be greater than the average thickness (T2) of the rim part. In other words, the relation T1>T2 holds.
