Definitions

  • the present invention relates to a driving device for the propulsion of waterborne craft, said driving device having a propulsion unit which comprises an endless flexible belt or chain element having driving projections and arranged between a pair of separate guide rollers or guide parts, at least one of which is rotatably drivable, said belt element having upper and lower parts of which the lower is adapted to be held in engagement with the water surface so as to propel the craft.
  • a propulsion unit which comprises an endless flexible belt or chain element having driving projections and arranged between a pair of separate guide rollers or guide parts, at least one of which is rotatably drivable, said belt element having upper and lower parts of which the lower is adapted to be held in engagement with the water surface so as to propel the craft.
  • a driving device of the type mentioned above is disclosed in FR patent specification 1,351,529.
  • the driving belt is however mounted in a frame whose front end is fixedly connected with the hull of the craft, viz. via a joint, while the rear end of the frame is suspended in a vibration-absorbing device which comprises a spring arrangement and hydraulic shock absorbers.
  • a vibration-absorbing device which comprises a spring arrangement and hydraulic shock absorbers.
  • the driving device can be used only for craft which have been especially designed to fit the driving device.
  • the driving device thus is not universally useful for different types of hull.
  • the driving device according to FR 1,351,529 is mounted in a position that is fixed once and for all, which makes it necessary to steer the craft by means of a separate rudder.
  • the present invention aims at providing a driving device which is universally useful for different types of craft and which in itself can steer the craft without assistance from any separate rudder.
  • this is achieved in that the propulsion unit is adapted to be supported at the lower part of a mounting which extends up to one or more attachments for attaching the mounting and, thus, the driving device in its entirety to said craft, the only connection between said propulsion unit and said craft being the mounting and the attachment.
  • a considerable advantage of the inventive driving device is that the actual propulsion unit can be used to steer the craft, either in that the unit is pivoted relative to the craft, or in that two different driving belts are caused to operate at different propulsion speeds. Since the propulsion unit is supported by a mounting, the driving device in its entirety can be mounted on any desired type of hull.
  • the driving belt or belts will serve as a hydrofoil, which helps to hold the moving craft in a comparatively elevated position in the body of water in which the hull of the craft has a minimal frictional resistance to water.
  • FIG. 1 is a schematic side view of an inventive driving device connected to a boat
  • FIG. 2 is an end view from behind of the same device
  • FIG. 3 is a top plan view illustrating different pivotal positions of the device.
  • the drawing illustrates a driving device which in its entirety is designated 1 and is connected to the stern of a boat designated 2, in particular of small size.
  • the device 1 is an outboard motor which in known manner comprises a motor casing 3 and a mounting 4 extending downwardly therefrom and comprising one or more attachments 5 for attaching the device to the boat.
  • a propulsion unit 6 which does not consist of a propeller as in connection with conventional outboard motors but instead consists of at least one endless flexible belt or chain element 8 having driving projections 7 and arranged in per se known manner between a pair of separate guide rollers or wheels 9,9', at least one of which is drivable via a transmission (not shown) included in the mounting.
  • the endless driving belt 8 thus comprises upper and lower parts 10,11 of which the lower part 10 is adapted to be held in engagement with the water surface so as to propel the boat.
  • the device 1 comprises two substantially identical driving belts 8,8' arranged on opposite sides of the mounting 4 which extends vertically downwards, two casings 12,12' being connected with the mounting and covering the upper part of the driving belt and the guide wheels 9,9', said casings being down ⁇ wardly open and comprising means for mounting the axles of the guide wheels or rollers.
  • These axles are in turn inserted with their one end into the mounting and are there connected with a suitable mitre gear or worm gear which is, in turn, connected with a vertical drive shaft which is conventionally included in the mounting and associated with the motor.
  • Each of the front guide rollers 9 of the two driving belts 8,8' thus are rotatably drivable by the motor which is accommodated in the casing 3 and advantageously consists of a conventional internal combustion engine, for example a petrol engine.
  • the only connection between the mounting 4 (and thus the driving device in its entirety) and the hull of the boat 2 consists of the attachment 5, which means that the driving device can be mounted on many different types of boat without necessitating any modification of their hulls or a special design to fit the driving device.
  • a body 13 which fills up at least the main part of said space so as to prevent water from flowing through the space.
  • This filling body can advantageously comprise a metal sheet shell.
  • the length of the filling body should be as great as the distance between the rotatable wheels or rollers 9,9', while its width is approximately as great as the length of the wheels or the width of the belt, its height or thickness being as great as the diameter of the wheels. In practice, this diameter can be in the range of 100-200 mm, preferably about 150 mm.
  • the distance between the front and rear wheels 9,9' should be at least about 400 mm, while the width of the individual belt can advantageously vary in the range of 150-300 mm.
  • the front and rear ends of the filling body 13 conveniently have rounded recesses matching the circular circum- ference shape of the wheels 9,9".
  • the two driving belts 8,8' should in practice be adjustably movable and lockable in different positions relative to the water surface.
  • the driving belts should be adjustable not only in the vertical direction relative to the craft 2, but also at different, desired angles relative to the plane of the water surface, in that the belts should be adjustable in positions in which they are at least slightly inclined upwards-forwards in the driving direction.
  • the adjustability of the driving belts can be realised in various ways. One way is to make the casings 12 in which the belts are mounted, adjustable and lockable relative to the mounting 4. A further way is to permanently connect the casings with the mounting and make the mounting adjustable at different angles relative to the mounting 5 which is used for mounting the driving device on the craft. It is further conceivable to make the driving belts adjustable and lockable in the vertical direction relative to the mounting or, alternatively, to make the mounting adjustable and lockable relative to the attachment 5.
  • the driving direction of the driving wheels of the belt 8 suitably is reversible, such that the driving belts may be caused to drive the craft either forwards or backwards.
  • the steering of the craft can be realised in various ways.
  • the mounting 4 is intended to be rotatable relative to the attachment 5, so as to pivot the driving device in its entirety at a desired angle in relation to the keel line of the craft.
  • a further way is to provide the two driving belts 8,8 with separate drive means, such that the belts can be driven at various speeds and/or in different driving directions, whereby the steering can be effected by variation of the * , driving speeds and driving directions, respectively.
  • the inventive driving device can advan ⁇ tageously be designed to resemble an outboard motor, i.e. an internal combustion engine arranged directly on the mounting, the propeller being replaced by one or more endless driving belts or chains as described above
  • the driving device can also be designed with the actual driving source or engine positioned inboard, at the same time as the necessary power transmission to the driving belts occurs via suitable transmissions, for example in the form of hydraulic conduits from the driving source to a hydraulic motor arranged on the mounting, for example a hydraulic motor positioned midway between the two driving wheels or rollers 9 or, alternatively, inside a single driving roller for driving a single driving belt.
  • the two wheels of each driving belt can be designed with different diameters, more precisely in such manner that the sternmost wheel has a larger diameter than the one ahead, so that the lower part of the belt can be inclined.
