摘要： The invention relates to a milling machine having a replaceable milling drum, different types of milling drums being capable of being associated with the milling machine; and having a control unit for controlling the milling machine, machine parameters of the milling machine being settable by way of the control unit. Provision is made that the milling machine has associated with it at least one means that is designed to detect at least one characteristic feature of the milling drum; that the at least one means is connected to the control unit; and that the control unit is designed to specify for at least one machine parameter, indirectly or directly from the characteristic feature, a value to be set, and/or a setting range. The invention further relates to a corresponding milling drum and to a corresponding method. The milling machine, milling drum, and method allow the selection of machine parameters for operation of the milling machine to be simplified.

摘要： An earth working machine (10) encompasses a machine body (13) having a machine frame (12) and a drive configuration (46), rotationally drivable relative to the machine frame (12) around a drive axis (A) that defines an axial direction, that extends along the drive rotation axis (A) from an introduction longitudinal end (46a) at which the drive configuration (46) is embodied for introduction of a drive torque to a functional longitudinal end (46b) located axially oppositely from the introduction longitudinal end (46a), and to which configuration a working apparatus (32) embodied for earth working is releasably connected in torque-transferring fashion, in an operating position, for rotation together around the drive axis (A), such that when the connection is released, the working apparatus (32) is removable from the operating position in an axial direction relative to the drive configuration (46) for deinstallation from the drive configuration (46) and, for installation on the drive configuration (46), is conveyable into the operating position in an axial direction relative to the drive configuration (46), an actuator (65) being provided which is embodied to move the working apparatus (32) out of the operating position when the connection is released.According to the present invention, provision is made that an actuator housing (62) of the actuator (65) is provided on the drive configuration (46) for movement together therewith, at a position that is located closer to the functional longitudinal end (46b) than to the introduction longitudinal end (46a), an actuator member (63) of the actuator (65) being movable relative to the actuator housing (63).

摘要： The invention relates to an ejector unit, in particular for a road milling machine, having an ejector that is replaceably mounted on a carrier. In one aspect the ejector is curved in a scoop-like fashion. In another aspect the ejector is reversible upon the carrier to allow the ejector to be reversed after one wear surface is worn, thus presenting a new second wear surface.

摘要： The subject matter of the invention is a bit holder for an earth working machine, in particular a road milling machine, having a support member onto which an insertion projection is indirectly or directly attached on an insertion projection side, the insertion projection comprising at least one convex abutment surface and one pressure surface. In a bit holder of this kind, working forces can be dissipated in stress-optimized fashion into an attached base part when provision is made that the insertion projection comprises two convex abutment surfaces that are arranged at a distance from one another.

摘要： The invention relates to a bit holder for an earth working machine, in particular a road milling machine, that comprises a bit receptacle in the region of a working side of a support member and that indirectly or directly carries an insertion projection on an insertion projection side of the support member, the support member comprising two stripping surfaces [first or second stripping surfaces] that form a stripping surface pair and are at an angle to one another. In order to achieve a stable and long-lived configuration with such a bit holder, provision is made according to the present invention that the support member comprises at least one further stripping surface that is at an angle to the two stripping surfaces of the stripping surface pair.
