Engine mounting device (16) for a vehicle (10) suitable for connecting an engine (14) to a
vehicle frame (12), wherein the engine mounting device (16) is a one-piece
casting and comprises the following: - at least one contact plate (24), comprising: - a contact side (28) suitable for coming into contact with the
vehicle frame (12), - one of the sides (30) opposite the contact page (28), and - at least one through hole (32) extending from the contact side (28) to the opposite side (30), wherein the hole (32) is suitable for receiving a fastening screw (18) for fastening the motor mounting device (16) to the
vehicle frame (12), - at least two retaining plates (26) extending around the hole (32) on the side (30), characterized in that the retaining plates (26) extend perpendicular to the contact side (28) and are connected to each other by curved, partially hollow cylindrical connecting surfaces (44), and in that the retaining plates (26) define a receiving volume (34) which is adapted in its shape and dimensions to the shape and dimensions of a hydraulic fastening screw tightening tool (22) in order to receive it, and in that each retaining plate (26) comprises a
machined surface (33), wherein at least one
machined surface (33) defines the receiving volume, wherein the clamping volume (36) forms a partial
hollow cylinder (38), wherein the
diameter (DZ) of the
hollow cylinder (38) is at least 1.5 times the
diameter (DK) of the clamping hole (32), wherein the height (HZ) of the
hollow cylinder (38) is at least 3 times the
diameter (DK) of the clamping hole (32), and wherein a semicircular cylindrical surface (44) runs concentrically to the longitudinal center axis of the hole (32) between a side plate (40) and one of the reinforcement plates (42).
