Upper MacPherson strut step bearing for wheel suspensions in motor vehicles

An upper MacPherson strut step beating for wheel suspensions in a motor vehicle, comprising:

• a metallic housing with an axially extending annular housing wall and with a radially extending annular housing flange providing a radially extending housing edge, a collar edge with an axially extending collar edge wall, said collar edge wall being spaced radially inwardly of said housing wall, and a radially extending housing bottom wall extending radially inwardly from said collar edge wall to a central shock absorber support piece opening, said collar edge wall cooperating with said housing bottom wall to define a receiving space wherein said collar edge wall provides a radial limit for the shock absorber, said metallic housing being formed of sheet metal in one piece with said collar edge, said collar edge being provided at an underside of said metallic housing;
• a rubber buffer arranged in said housing;
• a support piece defining a part to be connected to a shock absorber, said support piece including radially extending projections extending into said rubber buffer and connected rigidly to said rubber buffer;
• an annular spring buffer for supporting a top end of a coil spring surrounding said shock absorber, said housing radially extending housing edge forming an abutment for said annular spring buffer;
• a housing cover which is to be fastened to a part of the motor vehicle, said housing cover including a radially extending annular part covering said rubber buffer on a top side of said rubber buffer and including an axially extending annular jacket flange, said metallic housing being pressed into said cover plate with said housing edge fictionally engaging said cover plate at a location adjacent to a transition between said housing cover radially extending annular part and said cover axially extending annular jacket flange to fictionally positionally fix said housing relative to said cover plate.
