1. A drive/drive suspension unit for an elevator installation, the drive/drive suspension unit comprising:
a drive;
a drive suspension for fastening the drive to a support element of the elevator installation;
wherein the drive suspension includes a rotary joint and an adjustment device, the rotary joint adapted to fasten the drive to the support element thereby enabling tiltably mounting the drive on the support element, and the adjustment device adapted to set a tilt of the drive about the rotary joint;
wherein the rotary joint includes a fixing part and a first suspension part, the fixing part adapted to fasten to the support element and the first suspension part being fastened to the drive;
wherein the fixing part and the first suspension part are rotatably connected to each other about an axis of rotation;
wherein the adjustment device includes a second suspension part fastened to the drive and connected to the fixing part;
wherein the fixing part and the second suspension part are displaceable linearly relative to one another to set the tilt;
wherein the fixing part includes a first sheet metal part and a second sheet metal part, the first sheet metal part being adapted to fasten to the first suspension part and to the support element, the second sheet metal part being adapted to fasten to the second suspension part, the first sheet metal part and the second sheet metal part being connected to one another by rivets, and the second sheet metal part being formed as a U-profile; and
wherein the support element extends in a vertical direction and the drive/drive suspension unit, when in an installed state on the support element, has a shaft of the drive with a friction drive pulley arranged on the shaft, the shaft extending in a horizontal direction perpendicular to the vertical direction.
