Abstract

A linear movement device has a housing and a carriage which can move in a longitudinal direction with respect to the housing, wherein the housing extends with an essentially constant U-shaped cross-sectional shape in the longitudinal direction, with the result that the housing bounds a guide cavity, wherein the guide cavity is covered with a toothed belt which extends in the longitudinal direction, wherein the toothed belt is attached at both ends to the housing with the result that said toothed belt defines a toothed belt plane, wherein at least one separate guide rail which extends in the longitudinal direction is arranged within the guide cavity, on which guide rail at least one separate guiding carriage is mounted in a longitudinally movable fashion, which guiding carriage is permanently connected to the carriage, wherein a first and a second deflection wheel, which deflect the toothed belt out of the toothed belt plane, are rotatably attached to the carriage, wherein a rotatable drive wheel, which is in drive-transmitting engagement with the toothed belt, is arranged between the first and the second deflection wheels. The carriage has a single-piece carriage base body which ex…
