A method and an apparatus 12 which uses or calculates a temperature gradient of a portion 16 of a vehicle 10 to determine a value equal to or representative of a time before a maximum allowable operating temperature is reached by the portion 16. If the value is less than a certain threshold, the apparatus 12 reduces the operating speed of the portion 16 and, in one embodiment, provides a warning signal to an operator of the vehicle 10.

The cable guide sleeve for an electric cable emerging from a tube according to claim 10 wherein the lateral opening in the casing of the tube is arranged in a part of the tube situated outside the axial guide path of the driven piston. 12. The cable guide sleeve for an electric cable emerging from a tube according to claim 10 wherein the end of the guide path is determined by an end stop, in particular in the shape of at least one indentation in the tube wall.
