Definitions

  • the present invention relates to a tractor truck, particularly intended for moving goods receptacles or so- called containers, and includes at least one front axle, one or more driving axles, a frame and a load coupling device at the rear portion of the vehicle for connecting the vehicle to the load or vehicle that is to be towed.
  • tractor truck which is described in the Swedish published specification 412 571, and which may be used for moving containers on board ship and in ports, and which gives good manoeuverability.
  • the drawback with this known tractor truck is that its driving wheels are turnable in relation to the vehicle chassis, which makes transmission very complicated and also results in problems with the vehicle tires, since the driving wheels will be relatively small and therefore very highly loaded.
  • the present invention has the object of providing a tractor truck primarily intended for moving wheeled containers or semitrailers and which is more stable and flexible, as well as cheaper to manufacture than known tractor trucks of this kind.
  • the inventive tractor truck is characterized in that the vehicle is turnably articulated at the load coupling device by means of a vertical shaft, said device being intended to be rigidly coupled to the load in the horizontal plane, while the vertical shaft is connected to torque-providing means adapted to turn the vehicle in the horizontal plane in relation to the load coupling device thus to steer the vehicle.
  • the advantage with a tractor truck in accordance with the invention is that together with the container or semitrailer it forms an inflexible rig which gives the driver a better view. Furthermore, the inventive vehicle cannot "jack-knife” for heavy loading, which also prevents the vehicle from losing steering ability due to lifting of the front wheels, as can be the case with known tractor trucks, e.g. those with a bearing plate or so-called "fifth wheel”.
  • tractor trucks e.g. those with a bearing plate or so-called "fifth wheel”.
  • the vehicle with load furthermore has a very small turning circle and good manoeuverability, which is essential for example in the confined spaces in question on a ship.
  • the tractor truck 1 illustrated on the drawing, is connected to a wheeled goods receptacle or container 2 via a coupling device 3 with a yoke 4 , which is coupled to one end of the container 2. At its other end the container is provided with removable wheels 5.
  • the device 3 is joined to the vehicle frame 6 via a vertical shaft 7 coupled to an unillustrated torque motor, intended to turn the vehicle, and thus steer it when the container 2 is coupled.
  • the vehicle then rests on the substructure with the aid of both driving axles 8 and 9, while the front axle 10, which is also the steering axle, is lifted from the substructure.
  • the front axle must be steerable, however, so that the vehicle may be driven without load.
  • the front axle may be steerable, either conventionally, or with the aid of so-called "waist steering".
  • the turnable attachment between the load coupling device and the vehicle frame may be stiff or articulated in the vertical plane.
  • the device 3 may be raisable and lowerable, e.g. with the aid of a lifting cylinder or lifting arm, or the wheels 8,9 may be raisable and lowerable in relation to the vehicle frame.
  • Moving the container 2 is accomplished by the vehicle 1 being driven in towards the container, the vehicle and container being afterwards coupled together with the aid of the coupling device 3.
  • the container end connected to the yoke 4 is then lifted by the device 3 being raised, or by the vehicle driving axles 8,9 being thrust out from the vehicle frame 6.
  • To reduce wheel scrubbing the front axle 10 is raised in the case where lifting the container is done with the aid of the device 3.
  • the vehicle may then be propelled forwards or backwards by the drive on axles 8,9 and the vehicle may be steered with the aid of the torque motor coupled to the vertical shaft 7. It should be noted that it is not necessary to raise the front axle 10 for driving the vehicle.
  • the vehicle does not need to have two driving axles, as in the illustrated embodiment, but may only have one axle or more than two should this be found necessary.
  • the front axle 10 may be lifted with such as pneumatic cushions from which the air can be evacuated, or by the entire vehicle being pivotable about a horizontal axis.
  • the steerable front axle may be dispensed with entirely, e.g. if the vehicle is centrally articulated or can be braked differently on its right- and left-hand sides.
  • a special embodiment of a tractor truck with a coupling device which is rigidly connected in the horizontal plane to the goods receptacle that is towed The invention is not restricted to this special embodiment, and it can include different variations within the scope of the claims.
  • the rigid coupling to the load in the horizontal plane may be achieved with the aid of a so-called "swan neck” with a horizontal tongue which is inserted in a recess in a special semitrailer on which the load rests.

Abstract

Un tracteur pour semi-remorque est conçu pour transporter des containers de marchandises, des remorques et des semi-remorques. Ce véhicule comprend un essieu avant (10) qui peut constituer en même temps un essieu de direction, et un ou plusieurs essieux moteurs (8, 9), un châssis (6) et un dispositif de couplage avec la charge (3) dans la partie postérieure du véhicule pour relier le véhicule au container de marchandises (2) devant être remorqué. Le châssis (6) du véhicule est articulé de façon pivotante au dispositif de couplage (3) avec la charge, par l'intermédiaire d'un arbre vertical (7), le dispositif de couplage avec la charge étant conçu pour être relié rigidement à la charge sur le plan horizontal. L'arbre vertical (7) est relié à des moyens produisant un couple (non représentés), adaptés pour faire tourner le véhicule, sur le plan horizontal, par rapport au dispositif de couplage à la charge, et pour diriger ainsi le véhicule et la charge.
