Linear drive arrangement

摘要

In a known linear drive arrangement, the piston rod of a working cylinder interacts with a gear and a driver in such a manner that, on a movement of the piston rod, the driver is moved in the direction of the longitudinal axis of the working cylinder via the gear. The known linear drive arrangement is relatively expensive in its construction. The invention proposes providing two working cylinders, the pistons (11, 10) and (22, 23) of which are rigidly interconnected via a common piston rod (13), the piston rod (13) being provided with a toothing (14). The toothing (14) of the piston rod (13) is in engagement with a first gear wheel (19) of two rigidly interconnected gear wheels (19) and (18). By means of the second gear wheel (18), a driver (35), designed e.g. as a chain, is driven, which is guided in a guide arranged parallel to the longitudinal axis of the two working cylinders. <IMAGE>
