摘要:
An adaptive advance control system for a construction machine senses the reaction forces applied by the ground surface to a milling drum, and in response to the sensed changes in those reaction forces controls the rate of lowering the milling drum into the ground surface. Early and rapid detection of such changes in reaction forces allow the control system to aid in preventing lurch forward events of the construction machine.

An adaptive advance control system for a construction machine senses the reaction forces applied by the ground surface to a milling drum, and in response to the sensed changes in those reaction forces controls the motive power applied to an advance drive of the machine. Early and rapid detection of such changes in reaction forces allow the control system to aid in preventing lurch forward events of the construction machine.

摘要:
The invention relates to a civil engineering machine for spreading material for spreading on soils or base materials, and in particular to a civil engineering machine for spreading binders for soil or base material stabilization, which has a container (3) for material for spreading to receive the material for spreading and a spreading arrangement (5) having one or more outlet openings for the discharge of the material for spreading. The invention relates in this case both to a civil engineering machine which is intended solely for discharging the binder and to a civil engineering machine, and in particular a stabilizer or recycler, which has a milling or mixing rotor by which, directly after the discharge, the binder can be mixed into the soil or base material which has been milled up. The anti-dust arrangement (7), which is arranged below the outlet openings, is characterized in that there is created below the outlet openings a spreading compartment (8) which is bounded by one or more first anti-dust members (7A, 7B, 7C, 7D) and in that there is created an anti-dust space (9) which is bounded by one or more second anti-dust members (8A, 8B, 8C, 8D). What is achieved in this way is that dust which occurs when the material for spreading is being discharged is first retained in the spreading compartment which is surrounded by the first anti-dust members, thus enabling the dust to settle on the ground. Quite a high proportion of the dust is trapped by this means at an early stage. The dust which is not retained in the spreading compartment is then captured in the anti-dust space which is surrounded by the second anti-dust members.

The invention relates to a stabilizer or recycler which has a rotor housing 8, in which a milling/mixing rotor 9 is arranged, and a unit 13 for discharging binder for soil or base material stabilization. In the civil engineering machine according to the invention, at least part of the supply container 14 for the binder, and in particular the part thereof which is of larger volume, is arranged to the rear of the milling/mixing rotor 9 in the direction of working. The center of gravity A of the supply container 14 is preferably arranged to the rear of the axis of rotation 10 of the milling/mixing rotor 9 in the direction of working. This special way in which the supply container is arranged gives an optimum weight distribution. Whereas the supply container 14, which is relatively heavy when filled with binder, is situated mainly to the rear of the milling/mixing rotor 9, the drive unit 12 of the civil engineering machine can be arranged ahead of the milling/mixing rotor. With the supply container and drive unit arranged in this way between the front and rear wheels 3, 4, the center of gravity of the civil engineering machine is situated in the region of the milling/mixing rotor 9, which is something that is aimed for in practice.

A fastening member-affecting zone is provided on a first side of the fastening shaft (26), and a supporting zone (78) that has supporting surface regions (88, 90) which are inclined relative to each other and adjoin each other in a transition zone (92) extending in the direction of the longitudinal shaft axis is provided on a second side of the fastening shaft (26), said second side lying opposite the first side relative to the longitudinal shaft axis. Said chisel holder is characterized in that the transition zone (92) is designed like a cavity, or/and at least some sections of at least one supporting surface region (88, 90) project radially outward from a basic outer peripheral surface (94) of the fastening shaft (26) in relation to the longitudinal shaft axis.
