Problems solved by technology

Rather protruding wheel housings would lead to an increase in the overall size of the ground compactor, which would be disadvantageous for maneuvering the ground compactor and its transport (e.g. on a truck)
In addition, accurate steering of the ground compactor is complicated by the operator, and the wheel rim of the rubber-tyred roller is not visible to the operator due to the presence of protruding wheel housings

Embodiment Construction

[0041] Similar or equivalent parts are indicated by the same reference numerals throughout the drawings. Repeated components are not necessarily shown separately in each figure.

[0042] figure 1 with figure 2 A universal ground compactor 1 with an operator's platform 2 and a frame 3 is shown. Furthermore, the ground compactor 1 comprises a chassis driven by a propulsion unit 4 , mostly a diesel combustion engine, which, as shown in the exemplary embodiment, comprises a front chassis section 5 and a rear chassis section 6 . During the working operation of the ground compactor 1 , it moves along the working direction a over the ground 8 and compacts it. figure 2 Details of the front chassis section 5 are shown. The front chassis part 5 comprises a steering device 7 and two chassis units 11 . The chassis units 11 each comprise two wheels 10 and a steerable support column 9 . The undercarriage units 11 are each designed to be rotatable about two vertical steering axes L e...

Abstract

The invention relates to a ground compactor (1), in particular a rubber-tyred road roller, for compacting the ground (8) along a working direction (a), the ground compactor having a frame (3), a supporting frame (3) chassis, the chassis comprises a front chassis part (5) and a rear chassis part (6), wherein at least one chassis part (5, 6) comprises at least two chassis units (11) and is formed for making the chassis unit (11) wheel housings (12) insulated from the external environment, each chassis unit (11) is rotatable about a respective steering axis (L) and includes at least one wheel (10), the wheel housings (12) include at least two wheels A cover unit (18), and a wheel cover unit (18) is arranged on each chassis unit (11), and the wheel cover unit is configured to be rotatable with the corresponding chassis unit (11) around a corresponding steering axis (L). Furthermore, the invention relates to a wheel cover (12) for a ground compactor (1).

Description

technical field [0001] The invention relates to a ground compactor, in particular a rubber-tyred road roller, for compacting the ground along a working direction. Furthermore, the invention relates to a wheel cover for use on a ground compactor. Background technique [0002] Typical ground compactors are used in such road and path construction, for example, where the ground compactor will compact and stabilize the ground before a base layer such as an asphalt cap is laid. Likewise, a base layer laid on compacted ground will be compacted and thus consolidated with a common ground compactor. Various ground compactors are known, such as road rollers, tandem rollers or rubber-tyred rollers, which are used for different applications. A general purpose ground compactor includes a frame and a chassis supporting the frame, the chassis including a front chassis section and a rear chassis section. These chassis parts can be, for example, the front and rear drums of a tandem roller....
