Abstract

A subframe for a motor vehicle, particularly for a rear axle of a motor vehicle, includes of a chassis frame which can be fastened to the vehicle body and which comprises at least cross members which are connected with side members. Bearings for suspension links are provided on the side members, and a transmission assembly is disposed in the chassis frame between the side members and the cross members. The side member structure of each side comprises in each case two members which are arranged above one another and which have a through-opening for axle shafts of the transmission assembly between one another and converge approximately at the end side and are connected with the cross members. By way of a three-point bearing, the transmission assembly is connected with the cross members and the side members, and the axle shafts of the assembly extend through the through-opening toward the wheel.
