Embodiment Construction

[0023] The tandem roller shown in FIG. 1 comprises a superstructure 1 with a cab, rolling bodies 2 and 3, which are mounted at front and rear under said superstructure 1 via a steerable rotary coupling 4. Between the two rolling bodies 2, 3 is an engine compartment 5 in which the drive motor, usually a diesel engine, is housed.

[0024] Such as figure 2 As shown, the front and / or rear rolling elements 2, 3 comprise two tire halves 6a, 6b arranged axially side by side and a corresponding radially extending tire end plate 7, the tire end plate 7 Has a central through hole. A corresponding bearing flange 8 is fastened on the tire end plate 7 . The two tire halves 6a, 6b are connected to each other so as to be rotatable about the axis of the rolling bodies via the two bearing flanges 8 and the spacer tube 9 via a bearing 10, for example arranged between the bearing flange 8 and the spacer tube 9 between the roller bearings.

[0025] The swivel coupling 4, which is steerably co...

Abstract

The invention relates to a compacting roll comprising at least one rolling body (2, 3) with a vibratory drive comprising a drivable exciter shaft (14) with an unbalancer, said shaft facing the rolling body (2, 3) Axially installed in the rolling body, the unbalancer includes an unbalanced cylinder (16) arranged centrally relative to the rolling body, the unbalanced cylinder is supported by the actuator shaft (14), and has a The axis of the unbalanced piston (17) is hydraulically adjusted radially by means of an adjustment device.

Description

technical field [0001] The invention relates to a compaction roll as defined in the preamble of claim 1 . Background technique [0002] In earthworks or road construction, it is desirable to compact unbound, hydraulically bound or bituminously bound material to a specified Proctor or Marshall density as quickly as possible, while preventing overcompaction , especially in the case of wearing layers, to reduce particle breakage of mineral components. [0003] On asphalt-containing road surfaces, smooth surfaces should be avoided during compaction in order to ensure a good bond between the layers or, in the case of wearing layers, a high holding force. In the case of bituminous materials, it is absolutely necessary to set optimal system parameters for a low number of compactions, since the cooling of the material reduces the compression plasticity and in the worst case the specified final density cannot be achieved. When compacting drain asphalt (open cell asphalt), the pores...
