초록 ▼

An actuating system, comprising a base part and a moving part, which can be moved by a compressively preloaded piston/cylinder assembly that comprises a cylinder and a piston rod, wherein a piston on the piston rod divides the cylinder into two working chambers, wherein the base part has an externally powered drive device that stands in operative connection with the moving part and functions in opposition to the operating force of the piston/cylinder assembly, wherein a control system monitors the motion of the moving system and detects an obstacle when a parameter representing the motion deviates from a stored parameter by a threshold limit, wherein the actuating system in the unpowered state holds the moving part with the aid of a locking device, wherein the locking device is formed by a flow connection between the working chambers of the piston/cylinder assembly and a pilot valve for controllably blocking fluid flow through the flow connection.

1. In an actuating system, comprising a base part and a moving part which can be moved by a compressively preloaded piston/cylinder assembly that comprises a cylinder and a piston rod, a piston on the piston rod dividing the cylinder into two working chambers, the base part having an externally powered drive device operatively connected to the moving part and functioning in opposition to the operating force of the piston/cylinder assembly, a control system monitoring the motion of the moving system and detecting an obstacle when a parameter representing the motion deviates from a stored parameter by a threshold limit, the actuating system in the unpowered state holding the moving part with the aid of a locking device, wherein the locking device is comprised by a flow connection between the working chambers of the piston/cylinder assembly and a pilot valve for controllably blocking fluid flow through the flow connection. 2. The actuating system in accordance with claim 1, wherein the pilot valve has a two-stage opening characteristic wherein, after a relatively large unblocking force is overcome, an operating motion of the piston/cylinder assembly can be performed with a smaller hold-open force. 3. The actuating system in accordance with claim 2, wherein the control system shifts the threshold value independently of an intermediate position such that the unblocking force is overcome by the drive device. 4. The actuating system in accordance with claim 2, wherein the control system has at least two threshold values, one threshold value is overcome for an obstacle during motion of the moving part and the second threshold value is overcome by the drive device when the moving part is set into motion from a stop. 5. The actuating system in accordance with claim 1, wherein, the base part includes a vehicle having an engine and a generator, and the pilot valve includes an electric actuator that is disconnected from the power supply of the generator and moved to a locking position when the vehicle engine is stopped. 6. The actuating system in accordance with claim 5, wherein a power supply from a battery can be connected to the power supply of the generator.
