<p>A linear drive (10) comprises a housing (12) forming an axial cavity (14), at least a first linear raceway (16) fixed relative to the housing (12), a carriage (22) provided with at least one guide (26) engaged with the first linear raceway (16) so as to guide the carriage (22) axially relative to the housing (12) between a first end position and a second end position, a threaded spindle (28) received in the axial cavity (14) of the housing (12), a nut (27) engaged with the threaded spindle (28) and attached to the carriage (22), a motor (30) located outside the axial cavity (14), closer to the carriage (22) in the first end position than to the carriage (22) in the second end position, and a coupling (32) for coupling the motor (30) to the threaded spindle (28). The coupling (32) is at least partially located in the axial cavity (14), axially between the nut (27) and the motor (30), and the carriage (22) in the first end position axially overlaps the coupling (32), to reduce the overall length of the linear drive (10).</p> |
