LINEAR DRIVE, LONGITUDINAL ADJUSTMENT UNIT WITH SUCH A LINEAR DRIVE

The present invention relates to a linear drive (1) comprising at least one toothed rack (20) oriented along a longitudinal axis (L) and at least two sliders (30) that are movable transversely to the longitudinal axis (L), and a drive shaft (60), wherein the at least two sliders (30) are coupled to the drive shaft (60) in such a manner that the at least two sliders (30) each perform at least one cyclic motion that is phase-shifted relative to one another in the course of one revolution of the drive shaft (60) and thereby push themselves through an operative contact with the at least one toothed rack (20) to generate a propulsive force in a direction of the longitudinal axis (L), wherein the linear drive (1) comprises at least one compensation means (15) through which the operative contact between at least one of the at least two sliders (30) and the at least one toothed rack (20) is prestressed.
