A front frame structure for receiving a pivotally mounted truck driver's cab is provided. The structure includes a mounting bracket for the connection of the pivotable driver's cab, which mounting bracket is fastened to the frame structure at connecting points, and with at least two longitudinal frame members which extend essentially along the longitudinal axis of the truck in the upper region of the frame structure. The longitudinal frame members themselves are designed with at least one deformation region for absorbing frontal collision energy, and the mounting bracket is arranged and designed to pass on collision energy from the driver's cab to the level of the longitudinal frame members.
