The invention relates to a running gear structure (4) for a commercial vehicle. The running gear structure comprises a lower transverse strut (8) and an upper transverse strut (9). The lower transverse strut (8) and said upper transverse strut (9) are fixedly connected to each other. The upper transverse strut (9) comprising two recesses (12, 13) which limit a space (14) located above the lower transverse strut (8). The space (14) is open at least in upper direction and dimensioned for accommodating a suspension spring (6). Preferably, an axle body and longitudinal swinging arms (22, 23) of the running gear structure (4) have a skeletal design with a plurality of struts (5). It is possible that the running gear structure (4) is L-shaped in a side view. Here, one leg of the L is formed by a horizontal structure part forming the longitudinal swinging arms (22, 23) whereas the other leg of the L is formed by a vertical structure part forming the axle body.
