Wheel-guiding forward axle air spring strut

A forward axle air spring strut for guiding a wheel in a motor vehicle having a chassis, the air spring strut comprising:

• an air spring including:
• an air spring cover defining a longitudinal axis;
• an air spring piston;
• and, an air spring flexible member connected pressure-tight and tension-tight between said air spring cover and said air spring piston;
• a shock absorber integrated axially into said air spring;
• said shock absorber including:
• a shock absorber cylinder;
• and, a shock absorber rod axially displaceable and rotatable in said shock absorber cylinder;
• a housing fixedly connected to said chassis;
• an elastic support non-rotatably seated in said housing so as to be non-rotatable with respect to said housing and said chassis;
• said shock absorber rod being articulately connected to said chassis via said non-rotatable support and said housing;
• said housing and said air spring cover conjointly defining an interface;
• a rotational bearing for connecting said air spring to said chassis separately from said shock absorber via said housing;
• said rotational bearing being mounted at said interface so as to permit said air spring to rotate about said longitudinal axis relative to said non-rotatable support and said shock absorber;
• a seal also mounted at said interface;
• said rotational bearing and said seal being mounted so that said bearing and said seal can be subjected to torsion when the wheel is turned for steering said motor vehicle;
• said cover, said piston and said air spring flexible member conjointly defining a pressure space;
• said seal being mounted above said rotational bearing;
• and,
• said rotational bearing being mounted in said pressure space of said air spring.
