Drive system

A drive system, comprising a linear drive which has a drive housing and a drive unit, wherein the drive unit is displaceable with respect to the drive housing in the axis direction of a longitudinal axis of the linear drive whilst carrying out a linear drive movement and is positionable in different stroke positions, wherein the drive unit comprises a driven section which is accessible outside the drive housing, moves along a linear stroke path given the drive movement and comprises an assembly interface which is designed for the attachment of a working unit which is linearly displaceable by the drive movement of the drive unit, and

• (a) wherein the linear drive is a double-acting fluid-actuated linear drive whose drive unit comprises a drive piston which is arranged in the drive housing, is coupled in movement to the driven section and in the drive housing axially divides off two drive chambers from one another, said drive chambers being able to be subjected to a fluidic pressure medium in a controlled manner for moving and positioning the drive unit,
• (b) that-wherein an electrically actuatable control valve device is arranged on the drive housing of the linear drive, said control valve device being designed for the controlled fluid subjection of the two drive chambers and on the one hand being in fluid connection with the two drive chambers of the linear drive each via a drive channel and on the other hand for the receiving and for the delivery of a fluid pressure medium communicating with a fluidic main connection device, said main connection device comprising a main fluid supply connection which is provided for connection to a pressure source and a main fluid delivery connection which is provided for connection to a pressure sink,
• (c) wherein an internal electronic control device of the drive system which is electrically connected to the control valve device for control purposes is arranged on the drive housing of the linear drive,
• (d) wherein two drive pressure sensor devices which are designed for detecting the fluid pressure which prevails in the two drive chambers and which for the transmission of electrical pressure signals are electrically connected to the internal electronic control device are present,
• (e) wherein the linear drive is provided with a displacement measuring device which is suitable for detecting the momentary actual stroke position of the drive unit and which for the transmission of electrical position signals is electrically connected to the internal electronic control device,
• (f) wherein the internal electronic control device comprises a closed-loop control electronics, by way of which the control valve device is electrically controllable in a closed-loop controlled manner with respect to pressure for the actuation of the drive unit in a closed-loop controlled manner with respect to position whilst taking into account the position signals which are delivered by the displacement measuring device and the pressure signals which are delivered by the two drive pressure sensor devices,
• (g) wherein a bending-flexible electricity cable arrangement is connected onto the internal electronic control device, said electricity cable arrangement being designed for the electricity-transmitting electrical connection of the internal electric control device to at least one electrical actuator device of the working unit, said working unit being fastened to the assembly interface, and
• (h) wherein a bending-flexible fluid tube arrangement which is designed for the fluid-transmitting fluidic connection of the fluidic main connection device to at least one fluidic actuator device of the working unit is connected onto the fluidic main connection device, said working unit being fastened to the assembly interface.
