METHOD FOR PRODUCING A RACK |
摘要 |
The invention relates to a method for producing a rack (5) for a rack-and- pinion steering in motor vehicles, which method consists of the following steps: a slug (18) for the rack (5) has a shape which differs from that of a regular cylinder at least in the area of the teeth. The size and shape of the cross-section of said slug (18) is chosen so that the outline of the finished rack (5) in the toothed area (7) does not extend beyond a tooth trace defined by the dimensions of pieces adjoining the rack-and-pinion steering. The rack (5) is shaped from the slug (18) by tumble forging. After tumble forging has been completed, the rack (5) has a convex or concave longitudinal profile, which serves to support the moments of tumbling during tumble forging, in its toothed area (7) outside the teeth. |
