대표청구항 ▼

The invention claimed is: 1. Trench cutter comprising: at least first and second drive trains, at least first and second pairs of coaxial cutting wheels, the first pair of coaxial cutting wheels being rotatable about a first axis of rotation in a first rotational direction, and the second pair of coaxial cutting wheels being rotatable about a second axis of rotation in a second rotational direction opposite the first rotational direction, the first and second axes of rotation being transversely offset from each other, and the first and second pairs of cutting wheels being driven in the first and second rotational directions, respectively, by the first and second drive trains, a gear arrangement including a sun wheel, the sun wheel being arranged in a substantially central position between the two transversely offset axes of rotation, the sun wheel driving the first and second drive trains, and a single drive motor driving the at least first and second pairs of cutting wheels jointly by means of the gear arrangement. 2. Trench cutter according to claim 1, further comprising radially protruding cutting teeth provided on the pairs of cutting wheels, the cutting teeth being arranged in a meshing manner during operation. 3. Trench cutter according to claim 1, further comprising a cutter housing, wherein the drive motor and the gear arrangement are arranged in the cutter housing. 4. Trench cutter according to claim 3, wherein the trench cutter is mounted on a telescopic rod and in the direction of the axes of rotation the thickness of the cutter housing is smaller than or equal to the maximum diameter of the telescopic rod. 5. Trench cutter according to claim 1, further comprising a main drive shaft arranged between the drive motor and the sun wheel. 6. Trench cutter according to claim 1, wherein the drive trains are arranged at an acute angle to the axis of the sun wheel. 7. Trench cutter according to claim 1, wherein the drive trains are arranged approximately at a right angle with respect to each other. 8. Trench cutter according to claim 1, wherein the drive trains each have at least one transmission gear.
