摘要： The invention relates to a quick-change holder for a quick-change chisel holder system for fastening a rotationally symmetrical milling chisel to a milling roller of a road milling machine, comprising a quick-change holder body, a chisel shank receptacle running along a longitudinal center axis in the quick-change holder body for receiving a chisel shank of the milling tool, a quick-change holder cone, which is formed by the quick-change holder body, lies in extension of the chisel shank receptacle, and for this purpose is designed to be clamped in an at least partially complementary holder receptacle of a basic holder of the quick-change chisel holder system, a tension means bearing arranged on the quick-change holder cone and designed to engage a tension means, with which the quick-change holder cone can be clamped on the basic holder in the direction of a cone axis of the quick-change holder cone, wherein the chisel shank receptacle and the tension means bearing are designed in such a way that the longitudinal center axis and the cone axis lie in a common plane and are angled relative to one another in this common plane. Furthermore, the invention relates to a quick-change chisel holder system and a milling roller.

摘要： A method for the maintenance or extension of the range of functions of a self-propelled machine, in particular a tandem roller, single-drum roller, rubber-wheeled roller, refuse compactor, road finisher, road milling machine, recycler or stabilizer, comprising the steps: generating a code which can be identified at a short distance by a control device of the machine either automatically by the control device after a maintenance interval has expired, or after a request by an operator for an extension of the range of functions, wherein the code contains information about at least one machine state that changes in the course of operation of the machine, identifying the code by a mobile terminal, transmitting the information contained in the code to a central server, transmitting a release code from the server to the mobile terminal, transmitting the release code to the control device of the machine, enabling the maintenance interval or the extension of the range of functions.

摘要： A drive apparatus in a self-propelled construction machine comprises a milling rotor and a main drive which can be coupled to the milling rotor via an engaging and disengaging clutch, and an auxiliary drive which can be coupled to the milling rotor alternatively to the main drive. The clutch is provided with a fixed side and an axially displaceable output side, which is displaceable between an engaged position and a disengaged position. The axially displaceable side is simultaneously also the engaging and disengaging part of a shiftable transmission, the fixed part of which is driven by the auxiliary drive, with the transmission and the clutch being engaged and disengaged in a selective fashion via the axially displaceable side of the clutch.
