Abstract

The subframe contains a framework which is cast as a single part and has profiled hollow members for the longitudinal and cross members. The cross members are connected to each other via supporting pillars at the corners, or are integrally formed on the supporting pillars. Arms which protrude outward are integrally formed on the supporting pillars or on the longitudinal and cross members, the end sides of which arms have connecting bearings toward the vehicle body. A differential is held on the two cross members, the differential having one mounting on the front cross member and two mountings on the rear cross member. The longitudinal members have a curved passage opening for the drive shafts of the differential. Mountings for wheel guiding links are arranged on the outside of the longitudinal member.
