  • the method according to the invention further comprises a forming step in which the steering housing or at least the rearmost of the insertion rings relative to the insertion direction are reshaped in order to fix the bearing and the insertion ring at least counter to the direction of insertion.
  • the insertion ring is spread or pressed by plastic deformation in a recess or circumferential groove in the inner wall of the steering housing to set him and the annular bearing in the axial direction.
  • the use of the insertion ring has the advantage that after disassembly and removal of Einsetzrings the possibility that the or a replacement bearing by forming on another, in the insertion direction, for example, in the axial direction of the housing section staggered point again Forming be fixed can, so that overloading and breakage of the metallic structure of the housing by a multiple plastic deformation are not to be feared.
  • the original steering box does not need to be replaced after repair.
  • the previously formed area is separated, for example, by machining or sawing.
  • the invention also relates to a repair method of a steering gear having a seat having a steering housing, wherein in the seat, an annular bearing and an insertion ring, for example, form-fitting, are arranged and for the axial fixation in at least one direction, the steering housing or the insertion ring is formed.
  • a steering gear that is at least partially mounted according to the assembly method described above.
  • This repair method according to the invention comprises the following disassembly steps: removal of the deformed area of the housing or of the formed insertion ring, for example by separation or largely undoing deformation; Removing at least the insertion ring and the annular bearing from the hollow portion.
  • the housing can be deformed both during manufacture and during repair, or alternatively in both methods the ring can be formed.
  • the "object" of the forming is preferably changed, for example, when the ring was formed during the production, the housing is formed during the repair and vice versa.
  • the repair method further includes the following assembly steps: inserting the annular bearing eliminating at least one of the insertion rings; second forming of the rearmost in the direction of insertion of the insertion rings or alternatively the steering housing offset in the direction of insertion in relation to the location of the original forming.
  • the section is the so-called pinion tower of the steering housing, in which the pinion and the steering shaft are rotatably arranged.
  • the shaping can relate to the region of the wall of the steering housing to which the outer circumference of the bearing or of the at least one insertion ring-depending on what is arranged last with respect to the introduction direction-is arranged adjacent.
  • the wall is pressed by forming in a circumferential groove in the outer periphery of the bearing or insertion ring.
  • the forming preferably takes place behind the stack with reference to the direction of introduction, directly behind the bearing or directly behind the insertion ring, for example by rolling.
  • the steering housing is made, for example, of a plastically deformable material, such as steel, or thermoplastic material.
  • all-steel housings have a number of advantages, including increased rigidity and toughness of the material.
  • the perceived steering precision is significantly increased by the stiffer steel housing.
  • Another advantage is the compact and inexpensive hydraulic cable routing of the steel housing, in which the Verschraubungsterrorismstellen omitted.
  • the housing which can be flexibly adapted to different vehicle types, is manufactured as a welded construction from formed, prefabricated precision steel tubes with strengths of 450 to 650 N / mm 2 depending on the degree of deformation. Corrosion protection is guaranteed by a special galvanic coating.
  • the welded-on hydraulic supply lines allow for optimal space adaptation in the vehicle.
  • the steering housing is provided by a seamless steel tube with a round cross-section.

  • at least one of the insertion rings is slotted, preferably at least the formed insertion ring is slotted.
  • the insertion ring is arranged behind the annular bearing.
  • the bearing is preferably arranged behind the Einsetzring in one embodiment. Furthermore, a "virgin" positioning of the bearing is achieved after the repair measure has been carried out, so that a wear-related play in the former seating area of the bearing is no longer a problem.
