ABSTRACT:
A vehicle in a driverless transport system has a drive unit which includes an electric motor, a gearing and a drive wheel with a common axis of rotation, is supported on the underside of the vehicle for pivotal movement about a vertical axis of rotation by a ring bearing, and serves only the driving and steering, the vehicle traveling on separate support wheels. A substantially horizontal bracket projects from both sides of a housing of the motor or gearing parallel to a plane of rotation of the drive wheel, one end of the bracket being supported for pivotal movement about an axis directed parallel with respect to the common axis of rotation on an arm extending downwardly from a support plate supported by the ring bearing, the other end of the bracket being supported with respect to the ring bearing by a substantially vertically acting spring arrangement pivotally supported on the bracket and/or the support plate. The spring arrangement can include an arrangement for changing the spring tension.
