Planet bolt and/or bearing bolt arrangement for transmission of motor vehicle, allows central region of planet bolt/bearing bolt to be recessed, where bolt borehole is designed throughoutly or partly in ribbed and/or reinforced manner

摘要

The arrangement allows a central region of a planet bolt/bearing bolt (1) to be recessed in a radially observed manner. An originating axial bolt borehole (2) is designed throughoutly or partly in a ribbed and/or reinforced manner. The borehole extends over an entire length or a part of the length of the bolt. A rib (3) is designed symmetrically to ensure the independence of attainable flexural rigidity in relation to installation positions and/or load zones, or asymmetrically. The bolt is produced by sintering or extrusion, and is used for lubrication of components of a transmission.
