20100244544 | Ejector Unit For A Road Milling Machine Or The Like - 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. | 09-30-2010 |
20110148178 | Bit Holder And Base Part - The invention relates to a bit holder having an insertion projection and having a holding projection, the holding projection comprising a bit receptacle, and the holding projection protruding at least locally from or beyond the insertion projection in the tool feed direction. A bit holder of this kind is designed in service-life-optimized fashion by the fact that the holding projection comprises a supporting segment having a rigid, shaped-on supporting surface that is arranged at least locally in front of the insertion projection in the feed direction. The invention further relates to a base part for receiving an aforementioned bit holder. | 06-23-2011 |
20110148179 | Bit Holder And Base Part For Receiving A Bit Holder - The invention relates to a bit holder having an insertion projection and having a holding projection having a bit receptacle, the insertion projection comprising a bearing segment and the holding projection comprising a supporting segment. In order to allow the bit holder to be braced in permanent and stable fashion with respect to a base part, provision is made according to the present invention that the supporting segment and/or the bearing segment comprise two supporting surfaces and bearing surfaces, respectively, arranged at an angle to one another; and that the longitudinal center axis of the bit receptacle and the longitudinal axis of the insertion projection enclose an obtuse angle. | 06-23-2011 |
20120086259 | Mixer Bar For A Stabilizer/Recycler - The invention relates to a mixer bar for a stabilizer/recycler, having an attachment side that comprises an attachment surface for mounting on a drum surface, and having a tool holder receptacle. A mixer bar of this kind can be configured in wear- and strength-optimized fashion, with little production outlay, if provision is made that the mixer bar is embodied as a forged part and has a cross-sectional profile that varies at least locally transversely to the tool feed direction. | 04-12-2012 |

20130241266 | Chisel Holder - The invention relates to 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 support member comprising two first and/or two second stripping surfaces that are at an angle to one another, and the support member having a working side that comprises a bit receptacle. In order to achieve a stable and long-lived configuration for such a bit holder, provision is made according to the present invention that the first and/or second stripping surfaces diverge from the insertion projection side toward the working side. | 09-19-2013 |
20130270891 | Chisel Holder - 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. | 10-17-2013 |
20130292991 | Ejector Unit For A Road Milling Machine Or The Like - 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. | 11-07-2013 |
20140117741 | Chisel Holder For A Soil Treatment Machine - 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. | 05-01-2014 |
20140265529 | Bit Holder And Base Part For Receiving A Bit Holder - The invention relates to a bit holder having an insertion projection and having a holding projection having a bit receptacle, the insertion projection comprising a bearing segment and the holding projection comprising a supporting segment. In order to allow the bit holder to be braced in permanent and stable fashion with respect to a base part, provision is made according to the present invention that the supporting segment and/or the bearing segment comprise two supporting surfaces and bearing surfaces, respectively, arranged at an angle to one another; and that the longitudinal center axis of the bit receptacle and the longitudinal axis of the insertion projection enclose an obtuse angle. | 09-18-2014 |
