Embodiment Construction

[0036] figure 1 A schematic view of an embodiment of a rear-loading road milling machine 2 according to the invention is shown. The road milling machine 2 has a frame 4, which in this embodiment is supported on three wheels 6, 6, 8, of which the two rear wheels 6, 6 (in the figure 1 Only one of the wheels can be seen in ) is arranged on the side of the rear area, while the front wheel 8 is arranged in the middle of the road milling machine 2 front area. The rear wheels 6, 6 are adjusted in height by means of hydraulic pressure, and the turning of the milling machine 2 is realized by the front wheels 8, which can rotate around the vertical axis A. Furthermore, such a road milling machine 2 can be carried by a sprocket drive in the position of the wheels 6 , 6 , 8 . In addition, the number of wheels or sprocket drive described above can be varied.

[0037] Inside the frame 4 there is at least one drive for the milling rollers, the wheels 6, 6, 8 and the hydraulic system, as w...

Abstract

The invention relates to a rear-mounted road milling machine with a milling roller (20), which is arranged in a downwardly open milling roller housing (16), between the front part (28) of the milling roller housing (16) and The opening (B) between the road surfaces (18) facing the direction of travel (a) is closed by a height-adjustable closing device (26), characterized in that the height-adjustable closing device (26) is wound in the direction of travel (a) The shaft (C) in front of the milling roller (20) oscillates. Oscillation of the closing device (26) around an axis (C) arranged in front of the milling roller (20) in the direction of travel enables the closing device (26) to slide on the road surface (18) and thereby adapt to unevenness of the road surface by oscillating back and forth Degrees such as fluctuations in the road surface or uneven distribution due to milling tracks. Thereby, interruption or cessation of propulsion due to jamming is eliminated. Furthermore, its closure (26) ensures protection against projecting milling objects forward.

Description

technical field [0001] The invention relates to a rear-mounted road milling machine with a milling roller arranged in a downwardly open milling roller housing, the opening in the direction of travel between the front part of the milling roller housing and the road surface having a height adjustable The adjustable closing device is closed. Background technique [0002] In the field of road construction, especially the repair and maintenance of traffic surfaces, road milling machines are mainly used today to process traffic surfaces. [0003] Its known road milling machine mainly includes the structure described below. The road milling machine comprises a frame which is supported on a wheel or chain drive. In addition, a milling roller is arranged on the machine frame, which is arranged in a milling roller housing whose milling roller housing is open downwards, ie towards the road. For conveying the milled material, hereinafter referred to as milling material, known road mi...
