Street construction machine for working on road surfaces

By using thrust members and deflection devices in road construction machinery, the vertical driving force is converted into horizontal pivoting motion, which solves the problem of large space occupied by the rear support wheels, achieves a more compact and flexible pivot unit arrangement, and improves Improved mechanical integration and walking performance.

Problems solved by technology

A disadvantage of the pivot unit disclosed in DE19631042C2 is that it requires a constant large space, mainly caused by the arrangement of the transmission on the horizontal plane
This leads to problems accommodating the pivot unit, especially in compact road building machines, especially in the "inward pivoted position"

Embodiment Construction

[0033] Hereinafter, the same reference numerals are used for the same elements. For clarity of the figures, each element that is repeated in the figures will not be relabeled in each figure.

[0034] The basic layout of the supporting wheels relative to the frame and the working device is as follows: figure 1 shown. figure 1 A schematic top view of a road construction machine, in particular a cold rolling machine, is shown. Correspondingly, the road making machine 1 comprises two front support wheels 2 , 3 and two rear support wheels 4 , 5 . The working device 6 is further represented on one side thereof ( figure 1 right side in ) is essentially flush with the rack. in accordance with figure 1 In the embodiment of the invention, the working device 6 is in particular a substantially cylindrical rolling drum, which is suitable, for example, for clearing road surfaces formed of concrete, asphalt or the like. For this purpose, the working device 6 is lowered onto the road su...

Abstract

A road building machine for road surface paving is provided. The machine comprises an automotive travelling mechanism with a steerable front axle of the undercarriage comprising at least one support wheel and two rear support wheels, a working device which is mounted in or on the machine frame and is approximately flush with said machine frame on one side, which is the so-called null side, a swivel unit having an articulation area formed by the machine frame and a swivel arm which carries the rear support wheel on the null side at its one end and is pivotably linked at its other end to the articulation area of the machine frame, with the swivel unit being arranged in the manner that it can be pivoted between an 'outwardly pivoted position' in which the rear wheel which is on the null side is pivoted outwardly to an outer end position parallel to the longitudinal direction of the machine frame and an 'inwardly pivoted position' in which the rear support wheel which is on the null side is inwardly pivoted to an inward end position which is parallel to the longitudinal direction of the machine frame, and a pivot gear which controls the adjustment of the swivel unit between the 'outwardly pivoted position' and the 'inwardly pivoted position' around a swivel axis.

Description

technical field [0001] The invention relates to a road construction machine for rolling road surfaces, in particular to a cold rolling machine for road surface laying. Background technique [0002] A common road-building machine is known for example from DE19631042C2, the main structure of which is quoted here. The roller compactor disclosed herein includes a motorized undercarriage. A total of four support wheels, two at the front and two at the rear, are arranged on the motorized running gear, only one front support wheel is known in the embodiments of this document. The chassis front axle is arranged to be steerable. Furthermore, a working device is provided which is mounted in or on the frame and is substantially flush with the frame. The working device is a cylindrical rolling drum in the housing of the cryogenic rolling machine, which is arranged, for example, in the rear region of the machine frame. Since the laminating drum is arranged substantially flush with th...
