Abstract
A method of producing a trailing arm of a torsion beam axle in which an integrated drive unit of a wheel-adjacent electric drive has an electric machine and a transmission. By using the method, the trailing arm is produced in the form of a casting with a box profile. The contours for producing the area that accommodates the transmission, the connection point to the vehicle body, the bore that receives the cross-member which connects the two trailing arms to one another, the U-profile of the trailing arm, the box profile and the area that accommodates the electric machine, are modeled by cores such that the contours for producing the connection point of the trailing arm to the vehicle body, the bore that receives the cross-member and the U-profile of the trailing arm are modeled by one core.
