Abstract (en)

[origin: US2018163351A1] Furthermore, the invention relates to a self-propelled construction machine, in particular a road milling machine or a surface miner, comprising at least one actuating unit of this type. The basic principle of the actuating unit according to the invention is the design of the cylinder of a piston/cylinder arrangement as a “locking bolt”. In the actuating unit according to the invention, a piston 27 is connected to the retaining part 26 and is surrounded by a cylinder 30, with a first cylinder chamber 31 being formed on one side of the piston and a second cylinder chamber 32 being formed on the other side of the piston. A cut-out 33 which extends in the direction of the longitudinal axis of the cylinder and through which the retaining part 26 extends is provided in the cylindrical wall of the cylinder 30. If one of the two cylinder chambers 31, 32 is supplied with a fluid, the cylinder 30 moves to one side or the other, while the retaining part 26 remains stationary. Therefore, the cylinder 30 constitutes a “locking bolt”, which can be pushed forward or pulled back.
