  • the engine mount according to the invention allows an installation position of the engine centrally under the unit and thus the optimal center of gravity is given.
  • the engine mount optimally accommodates the engine, the mechanical load due to the engine weight, as well as the acceleration forces and the belt tension. Also results from the engine mounting an acoustic decoupling of the engine by three elastic vibration sockets between the engine mount and the engine points.
  • the motor In the installation position, the motor is inclined axially to the rear by about one degree so that it assumes a horizontal motor position under the influence of belt tension.
  • this is designed as a drip and splash protection for engine and the connector, the connector is integrated here in the engine mount or in the engine mount with.
  • the engine mount Due to the design of the engine mount as a one-piece molded part, a number of components can be saved, which in particular allows automatic motor assembly.
  • the motor is in this case fixed to the shell element by means of two or three screws or pins, so that then the composite motor with bracket by means of two screws, such as M8 screws, can be attached to the bearing cross.
  • the bearing cross with two additional axial attachment points on the lower arms forms the mounting points for the engine mount.
  • the motor is fixed by means of the engine mount directly to the bearing cross, wherein the bearing cross is oriented such that the engine mount is attached to the downwardly facing bearing cross arms.
  • the engine mount is in this case formed as a molded part, which partially covers the engine and fixes it axially spaced from the drum axis in a central position below the tub.
  • the molded part is fastened between the two arms of the bearing cross pointing at an angle at an angle.
  • a further development of the invention that is Molded part of a curved shell element, which covers in the mounted state facing the housing front engine. As a result, the mentioned drip and splash water protection is given, so that the shell element extends here like a hood over the motor housing, the hood is also used here as a fixation for the engine on the bearing cross.
  • the shell element is open at its end facing the rear wall of the housing.
  • two formed as a hollow profile webs are formed at the open end of the end edge of the shell element by means of which a screw of the shell element between the arms of the bearing cross can be made.
  • the formation of these free ends as hollow profiles gives in particular the shell element in the region of the fixation a sufficient stability for the engine.
  • a stiffening sheet is additionally arranged between the webs, which is connected to the front edge of the shell element. This results in a further stiffening effect between the hollow profiles.
  • the shell element has niche indentations for fixing the motor underneath the arched shell element in its lateral areas.
  • the shell element in the rear region of its wall have a third fixed point for fixing the motor below the curved shell element.
  • This design now allows the motor to be firmly anchored beneath the camber, with niches formed in the camber in which the attachment points are provided to secure the motor to it under the domed shell. It is of particular advantage that the motor is mounted with elastic oscillating bushings below the shell element in order to provide an acoustic decoupling of the engine in this way.
  • the motor is arranged in an advantageous manner in the installed position below the shell member axially to the rear about a degree inclined, so that under belt tension influence a horizontal mounting position of the engine is effected.
  • a connection plug for the motor is made in the region of the shell element. This has an advantage especially in automatic engine mounting.
  • the shell element may in this case be made of a plastic molding or a die-cast molding.
