The clutch is spaced apart in the axial direction from the starter ring by an axial distance s, a forming reserved installation space for positioning an electric machine for a hybrid drive. The starter unit is positioned at least partially, preferably in large part, within the reserved installation space. A smaller installation space requirement for positioning a drive train in a motor vehicle body is possible by the sharing of the reserved installation space provided for the electric machine. ## Claims ### Claim 1 A starter arrangement for starting a motor vehicle engine of a motor vehicle, comprising: a starter ring for connecting to a drive shaft of the motor vehicle engine, a starter unit for introducing a starter torque into the starter ring via a starter pinion which can act on the starter ring, a clutch which is connected to the starter ring for coupling the drive shaft of the motor vehicle engine to at least one transmission input shaft of a motor vehicle transmission, the clutch being positioned spaced apart in the axial direction from the starter ring by an axial distance s, a reserved installation space for positioning an electric machine for the hybrid drive of the motor vehicle being formed by way of the axial distance s, the starter unit being positioned at least partially within the reserved installation space, and a clutch housing surrounding the starter ring and the clutch, the starter unit being positioned radially within the clutch housing, wherein the starter unit is connected to the clutch housing in a manner which is spaced apart via a sealing frame, and wherein the sealing frame encloses a cooling volume between the starter unit and the clutch housing, the cooling volume being connected to a surrounding area outside the clutch housing via at least one inlet opening in the clutch housing and at least one outlet opening in the clutch housing, the at least one inlet opening disposed below the outlet opening in the direction of gravity. ### Claim 2 (depends on 1) The starter arrangement as claimed in claim 1, wherein a cooling air flow which enters via the inlet opening and exits via the outlet opening sweeps over an outer side of the starter unit over an angular range α, wherein 45°≦α≦240°. ### Claim 3 (depends on 2) The starter arrangement as claimed in claim 2, wherein 60° a 180°. ### Claim 4 (depends on 2) The starter arrangement as claimed in claim 2, wherein 90° a 160°. ### Claim 5 (depends on 2) The starter arrangement as claimed in claim 2, wherein 120° a 150°. ### Claim 6 (depends on 1) The starter arrangement as claimed in claim 1, wherein the sealing frame has a holding clasp for receiving the starter unit in a clamping manner, the holding clasp being provided at least on an inner side which points toward the starter unit and an outer side which points toward the clutch housing with an elastic sealing material. ### Claim 7 (depends on 6) The starter arrangement as claimed in claim 6, wherein the elastic sealing material is vulcanized or adhesively bonded to the outer side of the holding clasp. ### Claim 8 (depends on 6) The starter arrangement as claimed in claim 6, wherein the holding clasp is metallic. ### Claim 9 (depends on 1) The starter arrangement as claimed in claim 1, wherein the sealing frame has at least one inner sealing lip which points toward the starter unit and/or at least one outer sealing lip which points toward the clutch housing, the inner sealing lip bearing against the starter unit in a substantially gap-free manner and/or the outer sealing lip bearing against the clutch housing in a substantially gap-free manner. ### Claim 10 (depends on 9) The starter arrangement as claimed in claim 9, wherein the inner sealing lip and/or the outer sealing lip comprise a noise insulating material. ### Claim 11 (depends on 1) The starter arrangement as claimed in claim 1, wherein the sealing frame is formed conically radially on the inside and/or radially on the outside in the axial direction in order to compensate for a mold-release slope of the clutch housing. ### Claim 12 (depends on 1) The starter arrangement as claimed in claim 1, wherein the sealing frame has an anti-rotation safeguard for the positively locking or frictionally locking connection to the starter unit and/or to the clutch housing. ### Claim 13 (depends on 1) The starter arrangement as claimed in claim 1, wherein the starter unit has a switching unit for actuating a starter motor of the starter unit, the switching unit being provided inside the clutch housing. ### Claim 14 (depends on 1) The starter arrangement as claimed in claim 1, wherein the starter unit can be inserted into the clutch housing for mounting by way of a movement in the axial direction, the starter unit being fastened to the clutch housing by way of screwing, via fastening means which run substantially axially parallel to a rotational axis of the starter pinion. ### Claim 15 (depends on 1) The starter arrangement as claimed in claim 1, wherein the starter unit has a fastening flange which protrudes in the radial direction from a motor housing of the starter unit for fastening to the clutch housing, the fastening flange bearing against the clutch housing by way of a bearing face which points away from the starter pinion. ### Claim 16 (depends on 14) The starter arrangement as claimed in claim 14, wherein the fastening means comprise one or more screws.
