    摘要： The invention relates to a new three-part process, which can also be employed on a large industrial scale, for the preparation of polyurea lubricating greases, which is characterised(a) in that polyureas which carry oleophilic groups are prepared by reaction of diisocyanates with amines either in the absence of a solvent on a reaction screw at 80.degree.-120.degree. C., preferably at 85.degree.-95.degree. C., (variant A) or in a toluene medium at 20.degree.-80.degree. C., preferably at 30.degree.-60.degree. C., (variant B),(b) in that, after complete reaction, the polyureas prepared according to (a) are ground in the solid, dry state to give powders (at least 70% by weight of the powder having particle sizes of about 100-400.mu.) and(c) in that the ground crude product, after being made into a "paste" (wetted) at elevated temperature in the base oil employed (10-30 minutes at 140.degree.-180.degree. C.) and cooled again to room temperature, is processed to a grease by complete homogenisation--if appropriate in several passes--in a high-pressure homogeniser under a pressure of 400-1,500 bar (spontaneous heating occurring up to about 100.degree. C.),greases having readily reproducible and essentially the same properties as in the case of the previously customary in situ manufacture being produced.

    摘要： In a process for manufacturing a vehicle body shell, the linking of an integral support to a forward structure of a known vehicle body shell may lead to tolerances which require readjustments of the axle geometry of the front axle. Accordingly, the bearing points of each wheel installation unit for the upper transverse control arm bearing which are situated behind one another in the longitudinal direction of the vehicle are brought to a defined distance range by a tensioning of the wheel installation unit, and a center fixation of the forward structure takes place relative to the longitudinal direction of the vehicle.
