Definitions

  • the invention relates to a drive for floatable vehicles, in particular amphibious vehicles.
  • a drive is described in DE-DS E5 20 292.
  • the drive motor is mounted in or on the vehicle and has one or more fixed drives for one or more propellers.
  • the drive shaft or the drive shaft of the propeller or the propeller can be adjusted in a vertical plane that is at least approximately parallel to the longitudinal axis of the vehicle and that can be locked so that it can be locked on a hollow shaft that is rigidly connected to the vehicle and has stationary drives.
  • the drive elements connecting the propellers with the fixed drives of the drive motor consisting of bevel gear and drive shaft, allow the drive shafts of the propellers to be deflected by an angle of 360 degrees.
  • the swivel radius of the propellers corresponds to approximately half the diameter of the propeller. In the case of a pivoting through an angle of 90 degrees, the space occupied by the propeller in one position still partially overlaps with the space occupied by the propeller in the other position.
  • a relatively poor efficiency of the drive is achieved because of the unfavorable inflow of water to the propellers caused by vehicle parts, while on the other hand at Driving in the country, the propellers are not adequately protected from possible damage in the intended position. Because of the risk of damage to the propeller drives, but also because of the vehicle parts which in the case of this known vehicle are necessary and protrude relatively far from the rear wheel axle, journeys through particularly difficult terrain are not possible with this vehicle.
  • the present invention has for its object to further improve a drive of the type described in the introduction in such a way that the drive can be better adapted to the respective operating conditions of the vehicle equipped with it. This object is achieved with the invention specified in the characterizing part of patent claim 1.
  • the drive according to the invention allows a vehicle equipped with it, for example an amphibious vehicle, to be maneuvered under relatively extreme conditions.
  • the efficiency of the propeller drive when the vehicle is traveling through water is considerably better than with the known drive, because because of the relatively large adjustability of the propeller drive in the vertical direction, the propellers can be brought to a water depth where the water flow of the propellers is practically no longer possible is adversely affected by any vehicle parts.
  • It also has the option such a low adjustability of the propeller drive has the advantage that the propellers can be brought into relatively dense water, so that for this reason and also the considerably decreasing stern wave generation, the efficiency of the propeller drive is further improved.
  • Experiments with a drive according to the invention have brought about an improvement in efficiency compared to the known drive by about 30%.
  • the drive according to the invention has the advantage that the drive with regard to the water depth present and also with regard to the respective load condition of the vehicle, e.g. a motor boat, can be optimally adjusted.
  • the propeller drives are arranged via drive linkages which can be displaced in the vertical direction, e.g. using profile spline shafts or the like. connected to the respective fixed output of the drive motor.
  • the adjustment or adjustment of the propeller drive in the vertical direction can e.g. via pull cables, racks or similar elements from the vehicle interior.
  • the propeller drives are additionally arranged in a manner known per se in a manner known per se around an axis of rotation located in the vicinity of the respective propeller vertical, at least approximately parallel to the vehicle longitudinal axis plane are rotatable or pivotable.
  • Fig. 3 shows the drive of FIG. 2 in plan view
  • Fig. 4 shows an advantageously further developed drive according to the invention in side view.
  • the propeller drive essentially consists of a hollow axle 3 rigidly attached to the longitudinal axis of the vehicle, at both ends of which bearing housings 4- for propellers 5 and their drive shafts are mounted.
  • the bearing housing 4 are pivotally mounted about an axis 8 on the hollow axis 3.
  • known cables and the like which are therefore not shown in the drawing, are used.
  • FIGS. 2-4 show the rear area of a vehicle 10 with rear wheel or rear wheels 11, which is provided with a drive according to the invention.
  • the vehicle 10 has a stationary output 12 in the rear area, to which a shaft 13 is connected, which is mounted in a hollow axle 14.
  • the hollow shaft 14 is fixedly connected to a gear housing 15, in which bevel gears and parts of the drive shaft of the propeller drive are mounted.
  • a hollow shaft 16 or 17 is provided on each side of the gear housing for receiving drive shafts, not shown.
  • the hollow axes 16 and 17 are rigidly connected to the gear housing 15.
  • a hollow stub shaft 28 or 29 is rotatably or pivotably mounted about an axis designated 43.
  • bearing housings 18 and 19 At the end of the hollow shaft ends 28 and 29 facing away from the gear housing 15 there are bearing housings 18 and 19, respectively, which serve to accommodate further drive elements such as bevel gears and drive shafts for driving a propeller 20 or 21.
  • Handlebars 22 and 23 are also rigidly attached to the transmission housing 15, the other ends of which are pivotally mounted in a bearing 24 or 25 on the vehicle 10 about an axis 26 or 27.
  • the axes 26 and 27 are aligned.
  • a gearwheel 30 or 31 which is connected in a rotationally fixed manner thereto and which is connected via a chain 32 or 33 to a fixed bearing 36 or 37 of the vehicle 10
  • Gear 34 or 35 is drive-connected.
  • Drive means leading to the vehicle interior, for example cable pulls, are connected to the gearwheels 34 and 35.
  • a hydraulic motor (hydraulic cylinder) 38 is provided for the height adjustment of the propeller drive.
  • the hydraulic motor 38 engages on one end on a bearing 39 fastened to the vehicle 10 and on the other end on a bearing 40 located on the hollow axle 14.
  • the hydraulic motor 38 can also be controlled from the interior of the vehicle 10 to a predeterminable extent.
  • the torque transmission from the fixed output 12 to the shaft 13 takes place in the case of the illustration according to FIG. 2 via a universal joint 42, which is protected by means of a bellows 41.
  • the bearing housings 18 and 19 with the propeller 20 or 21 can of course also be set in a position even when the propeller drive is completely raised with the aid of the aforementioned gearwheels and chains, which - especially when the drive is used at BoDten is important allow maneuvering in shallow water or with due consideration of the load on the boat.
  • the drive according to the invention has the advantage over the known drive that the propeller or propellers can be brought into positions which, viewed in the vertical direction, make up at least about twice the propeller diameter.
  • the drive according to the invention also has the advantage that, despite an adjustment of the propeller (s) in height or in the vertical direction, the propeller plane can nevertheless be held or adjusted in a desired orientation with respect to the longitudinal axis of the vehicle.
