Definitions

  • the present invention relates to a road milling machine with a driver's station having a bottom plate, and a steering device attached to the chassis of the construction machine, which has a console on which a steering wheel is arranged.
  • Road milling machines are known, on whose chassis a driver's station is provided.
  • the driver's cab provides space for the vehicle driver by creating a floor plate on which the driver stands.
  • driver's cabs are used, on the floor slab of which a seat opportunity is additionally provided for the vehicle driver so that the driver can also sit down for a longer processing of the traffic area.
  • the steering device of the known road milling machines generally comprises a console on which the steering wheel is arranged.
  • the console is arranged on a side facing the driver's cab, running closed side of the chassis.
  • the steering itself is usually done via a hydraulic system.
  • the known road milling machines have the disadvantage that monitoring or observation of the traffic area to be processed from the driver's station is made more difficult.
  • the milling tool is arranged in the direction of travel in front of the driver's station.
  • the milling tool is partially visible from the driver's cab by a recess in the bottom plate.
  • the disadvantage is that the view of the console with the instruments and the upwardly extending from the bottom plate steering column is obstructed. In addition, the legroom of the driver is also hindered.
  • a cold milling machine which has a arranged at the rear of the mill driver's cab with a driver's seat and a bottom plate.
  • a console In front of the driver's seat, a console is mounted above the bottom plate on the chassis of the milling machine, on which a steering wheel is arranged.
  • the driver's seat and the steering wheel can be adjusted to the size of the driver of the milling machine in order to always have the milling edge in view.
  • the steering device of the known milling machine is designed as a hydraulic steering, the controls (hydraulic unit) are arranged within the chassis.
  • the US-A-3,362,247 describes the driver's station of an agricultural machine comprising a driver's seat and a height-adjustable steering wheel.
  • the steering wheel sits on a steering housing that receives the hydraulics of the steering.
  • the steering housing is connected via a bent steering column, which is oriented substantially horizontally, with a housing which receives the operating elements. By turning the bent steering column, the steering wheel can be adjusted in height.
  • the present invention is based on the object to provide a road milling machine, which allows a simple and convenient observation of the traffic area to be processed from the driver's cab.
  • the road milling machine has a driver's station, which is provided with a bottom plate. On this floor plate, the driver can stand or even sit, provided that a corresponding seating is mounted on the bottom plate.
  • a steering device is attached, which serves the steering, for example, a wheel, the wheels of an axle or the crawler tracks on which a road milling machine is usually supported.
  • the steering device comprises a console and a steering wheel arranged thereon. Under a steering wheel in this context, any hand-operated steering means to understand.
  • the console is attached at one end to the side of the chassis. The term laterally refers to the direction of travel.
  • the console extends above the bottom plate to form an opening between the bottom plate and the console to the side.
  • the console is located higher than the bottom plate. An immediate arrangement of the console over the bottom plate is not required.
  • the other end of the console forms a free end.
  • the driver With the opening remaining underneath the console, the driver has the opportunity to observe the traffic area to be processed without having to lean to the side, as is the case with conventional road milling machines, where the side of the chassis obstructs the view at which the Console is arranged.
  • the one-sided mounting of the console causes a free end of the console is formed, which does not have to be supported down against the chassis, so that no visibility obstructing support means is required at this end.
  • the opening below the console ensures the driver greater legroom.
  • the recess of the floor plate, by which the driver recognizes the road surface, can either extend only over a part or the entire length of the floor plate.
  • the console of the road milling machine according to the invention need not be arranged laterally on the outermost side wall of the chassis, but can also be arranged offset inwards in the direction of travel behind a part of the chassis.
  • the console is offset inwards, wherein the chassis is recessed in the direction of travel before the opening so that the pavement is visible.
  • the steering wheel can be pivoted about the longitudinal axis of the console. This allows the position of the steering wheel on it be adjusted whether the driver operates the road milling machine standing or sitting.
  • the steering wheel can be pivoted together with the console.
  • further operating and / or display elements are arranged on the console, the relative arrangement is maintained to the steering wheel, so that the operation is simplified.
  • the steering wheel can be locked in different pivot positions.
  • Such a lock can allow a gradual or continuous adjustment of the pivot position.
  • the road milling machine according to the invention has a hydraulic steering, wherein the controls of the hydraulic steering are arranged within the console and can be operated via the steering wheel.
  • the road milling machine is designed such that the console is releasably attached to the chassis.
  • the road milling machine 2 has a chassis 4, which in the present embodiment is supported on three wheels 6, 6, 8, the two rear wheels 6, 6 (only one being in FIG Fig. 1 seen) laterally in the region of the rear and the front wheel 8 is arranged centrally in the region of the front side of the road milling machine 2.
  • the rear wheels 6, 6 are height-adjustable by means of a hydraulic, wherein the steering of the road milling machine 2 via the front wheel 8 takes place, which can be rotated about a vertical axis a.
  • a road milling machine 2 in place of the wheels 6, 6, 8 are also worn by crawler tracks.
  • the number of wheels or crawlers provided may vary.
  • At least one drive motor for a milling drum and the wheels 6, 6, 8 and a hydraulic system are also provided. Furthermore, the Provided known from the prior art additional units, which should be waived their representation for reasons of clarity.
  • the driver's station 10 is provided at the top in the rear of the road milling machine 2, where, inter alia, a seat 12 for the driver is located, which is arranged on a base plate 14.
  • the road milling machine 2 can be operated sitting by the driver both on the bottom plate 14 and sitting on the seat 12.
  • roller housing 16 Below the driver's station 10 is a roller housing 16.
  • the roller housing 16 is a downward, ie in the direction of the road surface 18, open housing in which a milling drum 20 is arranged, wherein the longitudinal axis of the milling drum 20 extends transversely to the direction of travel, in Fig. 1 is shown on the arrow b.
  • the milling drum 20 projects out of the roller housing 16 downwards in the direction of the road surface 18.
  • a height-adjustable stripping device 22 is provided at the rear end of the roller housing 16 in the direction of travel b.
  • a transport device 24 is provided, via which the milled milled material can be fed to an accompanying truck with a corresponding loading area (not shown). Since the milled material is fed to the truck via the rear of the road milling machine 2, it is a so-called rear-loading road milling machine.
  • the road milling machine can also be a so-called front loader.
  • a steering device 26 is furthermore provided which comprises a bracket 28 and a steering wheel 30 arranged on the bracket 28.
