Definitions

  • the present invention relates to a power train for an amphibious vehicle which power train comprises an engine and in-line transmission, with a power take off positioned between the engine and the in-line transmission of the vehicle and commonly known as a sandwich power take off.
  • the invention also relates to an amphibious vehicle having such a power train.
  • a power train which an engine and transmission are positioned towards the rear of the vehicle.
  • the weight of the power train is therefore positioned towards the back of the vehicle, which is necessary for good vehicle performance when the vehicle is in marine mode.
  • the position of the power train maximises the space available towards the front of the vehicle for the passenger compartment.
  • a power train is disclosed for use in amphibious military personnel carrier in U.S. Pat. No. 5,752,862 (Mohler).
  • the disclosed power train uses a rear mounted engine and a combined transmission and differential mounted at the front of the vehicle.
  • Mohler uses the drive shafts from the differential to drive caterpillar tracks, such drive shafts could also be used to provide drive to the front road wheels of a civilian amphibious vehicle.
  • the power train arrangement disclosed in Mohler has several disadvantages for application to such a civilian vehicle.
  • the location of the transmission at the front of the vehicle may reduce passenger and/or luggage space.
  • the arrangement requires a propeller shaft running through the passenger area. This shaft, which carries full engine power and rotates at engine speed, takes up valuable passenger space and will generate noise.
  • front wheel drive is not an optimal solution for a rear engined vehicle, as traction will not be as good as if the engine weight is placed over the driven wheels. This can give problems for example in take-off on slippery surfaces, and unusual on-road handling characteristics.
  • a power train for an amphibious vehicle which power train comprises an engine, an in-line transmission and a sandwich power take off being positioned between the engine and the transmission, the output from the power take off being adapted to transfer drive to a marine propulsion unit located at the rear of the amphibious vehicle, by means of a shaft which runs below or through the oil sump of the engine, or alongside the engine, characterised in that the output from the transmission is adapted to transfer drive to a differential located at the rear of the amphibious vehicle.
  • the differential is preferably located rearward of the engine.
  • the output from the power take off is in the form of an output shaft which is connected to a drive shaft which runs below or through the oil sump of the engine, or alongside the engine.
  • the oil sump of the engine may have a tunnel or recess through which the drive shaft passes.
  • the power take off is adapted to transfer drive to a marine propulsion unit located substantially in line with the engine and the transmission.
  • the output from the transmission is transferred to the rear differential through a transfer case.
  • the transfer case may also drive a differential located towards the front of the vehicle for driving the front wheels of the vehicle. This arrangement enables a four wheel drive facility when the vehicle is operated in land mode.
  • a marine drive decoupler may be provided so that drive to the marine propulsion unit can be selectively decoupled.
  • an amphibious vehicle having a power train in accordance with the first aspect.
  • FIG. 1 is a side view of a first embodiment of a power train in accordance with the invention, in which drive is provided to the rear wheels only;
  • FIG. 2 is a side view of a second embodiment of a power train in accordance with the invention, in which drive is provided to front and rear wheels.
  • power train 1 comprises an engine 2 , a transmission 3 , and a water jet 4 , the respective centre line of each being located substantially along the centre line of the amphibious vehicle.
  • the transmission may comprise a manual, sequential shift, semi-automatic, or automatic gearbox, or a continuously variable transmission (CVT).
  • a power take off 5 located between the engine 2 and the transmission 3 has an output shaft 6 driven by engine 2 , and is enclosed by a chain case 7 .
  • the power take off may be of any suitable type and may, for example, be constructed according to the applicant's co-pending British patent application No. GB0020884.3.
  • the output shaft 6 of the power take off is coupled to a drive shaft 8 which runs rearward to a marine propulsion unit 4 .
  • the marine propulsion unit is a water jet, but a screw propeller or any other suitable marine propulsion system may be employed.
  • a decoupler 9 is provided in the drive line from the power take off to the marine propulsion unit so that drive to the marine propulsion unit can be selectively coupled and decoupled.
  • such a marine drive decoupler is not essential and can be omitted.
  • the drive shaft 8 for the marine propulsion unit runs in a tunnel 11 through the oil-sump 12 of the engine 2 .
  • the drive shaft may run below the oil-sump or beside the oil-sump, on whichever side of the engine may be convenient, with the marine propulsion unit located accordingly.
  • Tunnel 11 may be fully enclosed as shown, or in the form of a recess in the sump, which recess is open at its base.
  • the transmission 3 is of a conventional longitudinal type.
  • the drive or output end 18 of the transmission is connected to a transfer case 13 which transfers drive power from the transmission 3 to an output shaft 14 .
  • the output shaft 14 is connected by a drive shaft 15 to a differential 16 , which is located between the timing end 17 of the engine 2 and the marine propulsion unit 4 at the rear of the vehicle.
  • the differential 16 transmits drive to the rear wheels of the amphibious vehicle via axle shafts in conventional automotive manner.
  • the transfer case 13 may comprise a driving sprocket rotatably fast with an output shaft of the transmission, and a driven sprocket rotatably fast with the output shaft 14 of the transfer case 13 , drive being transmitted between the two sprockets by means of a chain or belt.
  • FIG. 2 A second embodiment of the invention will now be described with reference to FIG. 2 in which common reference numerals are used to denote parts in common with the embodiment shown in FIG. 1 .
  • the power train 10 is essentially the same as the power train 1 shown in FIG. 1 , the only difference being that the transfer case 13 also provides drive to the front wheels of the vehicle by means of a forward drive shaft 19 and differential 20 .
  • a centre differential (not shown) may also be provided in or adjacent to the transfer case 13 .
