ABSTRACT:
A preassembly unit for the drive of an industrial truck, with a fifth wheel on which the driving wheel is rotatably mounted around a horizontal axis and which on its part is rotatably mounted in a bearing member around a vertical axis, a drive motor arranged on the fifth wheel, which is coupled with a driving shaft of the driving wheel via a gearbox, optionally a steering motor on the bearing member in order to turn the fifth wheel in the bearing member around the vertical axis, a parallel rod assembly between the bearing member and a frame of the industrial truck, which permits an essentially vertical movement of the preassembly unit in relation to the frame, and a spring arrangement between the bearing member and a frame-fixed section, wherein at least one upper drag rod of the parallel rod assembly is articulated on the lower end of a separate attachment section, which forms an interface with a counter-attachment position on the frame by attachment positions, and that at least one spring acts between a shoulder of the bearing member and an abutment of the attachment portion below the attachment positions.
