Abstract: A support assembly for a core drill which utilizes an improved high strength spoked reinforcer. The reinforcer may be removably mounted a core drill tube by fasteners. A drive connection is removably mounted and centrally located on an outer disc of a pair of discs. The drive connection is adapted to connect with a drive shaft to cause rotation of the tube. The assembly can also include a split in the disc when the high strength spoked reinforcer is not welded thereto, thereby providing a means of water control. The high strength spoked reinforcer can be a separate piece that is bolted to the disc or can be integrally formed as one piece therewith.

Abstract: A wheel for a motor vehicle has a wheel hub connected with a wheel rim by spokes. In order to create a wheel for a motor vehicle which has low weight and high stability, spokes arranged between the wheel hub and the rim are constructed such that, in first areas connected with the wheel hub, the spokes have solid cross-sections and, in second areas connected with the rim, the spokes have V-shaped cross-sections. Transitions between the two areas are progressive; that is, along a longitudinal course of each spoke from the wheel hub toward the rim, the cross-section of a spoke is changed from an initially solid cross-section, which preferably has an elliptical construction, to a triangular cross-section, which then further changes to a V-shaped cross-section while forming a groove arranged in its center.

The rim spider is connected with a rim by way of weld ring surfaces which are friction welded. The metal foam core is provided in a special manner with a partial core which is supported on a top core of a casting die tool so as to provide positioned bearing in the casting die tool. By way of slides, which are arranged in a distributed manner on a circumference of the rim spider, an influence on heating and cooling behavior, during and after casting, is exercised.

Abstract: A hub for use in and as part of a wheel support assembly adapted to bolt to the end plate of an axle of a vehicle for supporting a tire is disclosed herein along with the wheel support assembly itself. The hub is configured as a plurality of bars which are connected together to form a hub body. This hub body defines a common center point and a contact face. The contact face is where the hub is in contact with the axle end plate when the device is mounted to a vehicle. Each of the bars has on one side a contact surface, and a through hole for receiving an axle lug bolt. The contact surface on each of the bars has a curved shape on its outwardly most extending end, the curvature of which is defined by a radius less than the distance between the common center point of the hub body and the outwardly most extending end of the bars.
