  • Patent number: 7854280
    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 sho

  • Patent number: 7654350
    Abstract: Drive and steering unit for a wheel of a floor conveyor, in which a driving motor and a steering motor are disposed coaxially one below the other and are each one coupled via a drive gear or a steering gear, respectively, with a shaft of the wheel or the bearing equipment of the wheel, respectively, wherein one shaft extends as a hollow shaft and the other shaft extends through the hollow shaft, and an electronic control for the driving motor and the steering motor, which is connected with desired value transmitters for the rotational speed and the steering angle, characterised in that the electronic control has at least one circuit board which is coaxially arranged between the driving motor and the steering motor and/or the steering motor and the steering gear.
