Vehicle wheel having a connection between a wheel rim and a wheel disc and method for the production thereof
a technology of vehicle wheels and discs, which is applied in the field of vehicle wheels, can solve the problems of increasing the mass of the wheel rim, reducing reducing so as to improve the reliability and durability of the connection, reduce the effect of force transmittable with the connecting element or the connection arrangement thereby increased, and reduce the cross section and notching effect of the connecting element or the connection arrangemen

Benefits of technology
The technical problem addressed in this patent text is to improve the strength and durability of the connection between the wheel disc and wheel rim while keeping the mass of the connection low. The goal is to provide a method for producing such a vehicle wheel that is easy, cost-effective, and reliable.
Problems solved by technology
Particularly with sports cars or heavy vehicles with brakes of accordingly large dimensions, therefore, the space for the radial connection of the wheel disc to the well is limited.
In this case, the wheel disc or the spokes in the connection area must also be designed more solidly, which contrary to the lightweight-construction requirements placed on them results in a compactness of the wheel disc with an unfavourable mass.
In addition, through an arrangement of the connecting elements in the zone of transition from the well to the shoulder, the well must be designed according to the cross section of the connecting elements and the associated required size of the drilled holes and contact surfaces more deeply, which however, contrary to the interest in lightweight construction, increases the mass of the wheel rim.
If the possible size of the connecting elements is limited in any way, then in order to ensure the connection is secure the number of required connecting elements must be increased, which on the one hand requires greater effort and expense in terms of construction and installation, and on the other, again makes the weight assessment of the vehicle wheel worse.
Through the cyclical load placed long term on the vehicle wheel, the connection between wheel rim and wheel disc is particularly at risk from settling and creep phenomena and an associated autonomous loosening of the connection.
Since the contour of the tire seat, on the outer side of the rim, to be reproduced is changeable along the angle of rotation of the connecting element, a contour pre-fabricated on the connecting element would fit with the surrounding contour of the tire seat in only a few angle-of-rotation positions, which is less practical to execute.

Embodiment Construction
[0100]The first embodiment of the present disclosure shows, in FIG. 1, a sectional view of a vehicle wheel according to the present disclosure with a wheel rim 1 and a wheel spider 2 made from aluminium which are connected by means of several countersunk bolts 3 made from stainless steel arranged distributed around the circumference of the wheel rim 1. The sectional view shows the section through the vehicle wheel along the longitudinal axis of one of the connecting elements 3 guided through the rim base of the wheel rim 1 and joined in the wheel spider 2.
[0101]The attachment of the wheel spider 2 to the wheel rim 1 occurs in the area of a tire seat 1.1, which is formed in the rim base of the wheel rim 1 between the rim shoulder 1.2 (hump) and the rim flange 1.3 to accommodate a tire 4.
[0102]The radial outer contour of the essentially radially extended wheel spider 2 is adapted to the contour of the wheel rim 1 on the inner side of the rim beyond the tire seat 1.1, so that the wheel...

A vehicle wheel may include a wheel rim and a wheel disc connected to an inner side of the wheel rim. The wheel disc may be connected to the wheel rim by a connecting element that 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.
