Abstract
Amphibious vehicle (2, fig. 1) has road wheels 8 which are retractable to allow planing. Each wheel suspension is accomodated by a gap (80,fig 4) in the planing surface 20 of the hull. To reduce hydrodynamic drag and improve marine handling, covers 34 are provided which cover the gaps when the wheels are retracted. These covers may be hinged parallel to a longitudinal, or to a transverse, axis of the vehicle. The covers may be hung from suspension arms 40 or otherwise connected to hull 6. The covers may leave gaps (90,fig 4); to cover these, a second embodiment comprises "barn door" double covers (92, 94, fig. 5). A third embodiment has a mechanical linkage (182, fig. 7), which biases cover 180 to overlay gap 90 on wheel retraction. Tabs may be used (104, fig. 7) to prevent covers (180,fig 7) from being drawn above hull surface 20 when the wheels are retracted.
Description
AMPHIBIOUS VEHICLES WITH RETRACTABLE WHEELS
The present invention relates to amphibious vehicles, and particularly to hull Pairings for recesses in the hull.
In our co-pending Patent Application No. PCT/GB/04/002156, a planing amphibious vehicle hull is shown with recesses in the areas where retractable wheels and their suspensions move during suspension retraction and protraction. Because the suspensions are assembled from below during manufacture, the recesses intrude considerably into the planing surfaces of the hull. In order to reduce this intrusion, plates are fixed across part of each recess after assembly of tom suspension. These plates are currently glued into position, although they could be bolted. As will be seen from Figure - 1 of the above prior application, it is clear that particularly the front wheel recesses are very much open a= the bottom. As a result of the openings in the bottom of the hull, there can be problems with drag on the hull when the vehicle tramps through rough water. This is particularly problematic for vehicles smaller and lighter than that shown in the prior application.
A further known solution to this problem of reducing drag on water is disclosed in US 4,958,584, to Williamson. In this patent, a single sliding cover 18 (Figure 5) for front and back wheel wells 42 on one side of the vehicle is powered fore and aft by a double acting hydraulic cylinder 148. This arrangement appears to be a very simple and elegant solution, but has considerable practical drawbacks.
First, the slide channels will be susceptible to damage or seizure due to ingress of sand or silt. Second, the cover runs parallel to the hull for most of its length; so any grounding or collision damage which distorts either the hull or the cover would be liable to cause the two parts to jam together, preventing protraction of the wheels and stranding the vehicle on water.
Third, the use of a single actuator to move such a large and complex sliding panel is liable to lead at the least to uneven panel movement, and at the most to complete seizure, especially as wear and play build up as the vehicle ages.
Finally, a single cover as shown, which overlaps the hulk between front and rear arches even when closed, would project below the hull at the front, at least, of each wheel arch, disturbing the smooth flow of water along the vehicle2s .
planing surface. Clearly, fresh thinking is needed. . .
An object of the invention is, therefore, to further reduce .
drag on an amphibious vehicle when in water.
According to the invention, there is provided an amphibious vehicle having retractable road wheels each mounted by means of a wheel suspension to a vehicle body, the body having a planing bottom, wherein the bottom has for each suspension an interruption in the bottom through which at least a part of the suspension can move during retraction or protraction of its said road wheel, wherein the interruption is arranged to be substantially covered by a cover articulatedly fixed to the body, the cover so arranged that the cover at least partially opens on wheel protraction.
The fixture of the cover to the body of the vehicle may be hinged by means of a hinge or hinges, with hinge axes parallel to either the vehicle's longitudinal axis, or to its transverse axis. Alternatively, the cover may be movably arranged on a suitable linkage.
In a preferred arrangement, the cover is connected to a lower suspension member, so that when protracting the wheels, the lower suspension member carries the cover down with it. The linkage between the suspension member and cover may be extensible, so that when retracting the wheels, the suspension member may retract into the interruption in .- the hull; while the cover is constrained to remain flush,..
with the hull surface. .
.-- ' The covers may be hollow bodies, which provide buoyancy fo the vehicle on water. In this case, the covers may be made..
of blow moulded plastic. Alternatively, they may hake.
buoyancy foam attached. The covers may also be profiled to.
match the hull planing surface, with features like strakes continued across the cover surfaces.
Embodiments of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure l is a diagrammatic side elevation view of an amphibious vehicle according to the invention; Figure 2 is a transverse cross section through plane II-II of the vehicle of Figure l according to a first embodiment of the invention, with the wheels retracted; Figure 3 is a transverse cross section through plane II-II of the vehicle of Figure 1 according to a first embodiment of the invention, with the wheels protracted; s Figure 4 is a view from below the vehicle of Figure 1 with the wheels retracted; Figure 5 is a transverse cross section through plane II-II of the vehicle of Figure 1 according to a second embodiment of the invention, with the wheels retracted; Figure 6 is a view from below the vehicle of the seconders embodiment with the wheels retracted; and . ë es
Figure 7 is a transverse cross section through plane II-I.
Of the vehicle of Figure 1 according to a third embodiment of the invention, also with the wheels retracted. :e'' ..
Amphibious vehicle 2 has a prime mover 4 driving a pump jet 6 through a marine transmission. Locomotion on road is provided by wheels 8, which are driven through a road transmission. The wheels are shielded by wheel arches 12.
The vehicle body comprises an upper body 14 and a hull 16, which are formed separately and joined at split line 18. A chassis is also provided, as is described below. If this chassis is bonded to the bodywork, it may be regarded as part of the overall body structure. The hull has a planing surface 20. A driver's seat 22 is provided with one or more passenger seats 24 astern of the driver's seat. The seating axis is on the longitudinal axis of the vehicle, or parallel thereto. The axis of the prime mover is also along, or parallel to, the longitudinal axis of the vehicle. Driver controls are provided, in this case handlebars 26. A windscreen 28 is provided for weather and spray protection.
Figures 2 and 3 show a pair of rear wheels 8 mounted on hubs 54. The hubs are driven by intermediate shafts 62 and layshafts 60, which are driven from the prime mover 4. The intermediate shafts are supported inside lower suspension members 40 respectively which are each in the form of a tube. The tubelike members 40 are pivotally mounted at their inner ends on bearings 42. The outer ends of members are connected to upright members 52, which carry hubs 54.
Upper suspension members 56 connect between vehicle chassis and upright members 52. .
15. ..
As can be seen in Figure 4, hull 16 has a planing bottom 20, in which there are gaps 80 forming interruptions in t bottom through which lower suspension members 40 can move' . from a retracted position of the wheels as shown in figure 2, to a protracted or wheels down position as shown into ..e Figure 3. .
Fixed to lower suspension members 40 are covers 34, which are fixed by means of inner and outer brackets 36 and 38 (Figure 3) to members 40, so that the covers pivot about bearings 42. Gaps 80 are defined by body edges 84, 86, and 88. Covers 34 when closed substantially fill gaps 80, only leaving small clearance gaps 90 necessitated by the need to distance the outer faces of the covers from the centres of bearings 42.
In order to achieve complete filling of clearance gaps 90, a second embodiment has a pair of covers 92 and 94 for each interruption in the hull surface, which are hinged at 96 and 98 on one side and at 100 and 102 on the other side of the planing surface 20. This is shown In Figures 5 and 6. Door 92 is shown figuratively in an open position here, although the suspension is retracted; on the right hand side of the Figure, a dashed outline of the corresponding door is shown.
Each cover 92, 94 of each pair hinges about a transverse axis of the vehicle so as to fill half of each gap 80. The covers are split into pairs in "barn door" style to reduce downward protrusion below the hull surface 20 when the covers are open. The covers may be made flexible to avoider.
Is breakage on striking rocks, etc. They may also protect the wheel suspensions from impact damage, e.g. scratching of anti-corrosive coatings. The simplest and most foolproof.
means of opening these covers is to arrange for them to by.
held shut by springs 110 and 112 (Figure 5) when wheels are retracted, and pushed open by the suspension as the wheeled protract. Alternatively, mechanical linkages to the wheedle suspensions may be arranged. Such linkages could be designed to impart a translating movement to the covers, so that they move transversely across the vehicle before or during deployment.
It may be found that the travel of hull gap covers attached to suspension members is preferred to be less than that of the retractable suspension. Particularly where a narrow hull is combined with a large vee angle, as seen in the Figures, it will be necessary for the wheels to be tipped up at a large angle to the road position to keep them above the water line when cornering on water. In this case, if the covers are constrained to move through the same angles as the lower suspension members, covers which are flush with the hull when the wheels are retracted may hit the ground when the wheels are protracted; conversely, covers which as shown in figure 3, clear the ground adequately in road mode, will be drawn up above the hull line when the wheels are retracted.
This mechanical contradiction may be averted by breaking the fixed mechanical link between the covers and the suspension members. Figure 7 shows such an arrangement with the wheels retracted. Cover 180 on the right hand side of the Figure (left hand side of the vehicle) is shown retracted, as ib would be with the wheels retracted; but cover 180 on the left hand side of the Figure (right hand side of the vehicle) is shown figuratively in a protracted position, .
show linkage 182. .
When the suspension is protracted, covers 180 are pushed .
down below planing surface 20 by stops 194 mounted on the lower suspension members. In this position, covers 180 are stabilized by linkages 182. When the suspension is retracted, pins 194 also retract; and covers 180 are pulled up towards surface 20 by tension springs 192, which are tethered above surface 20. The suspension members will be pulled up inside the hull as far as is required to fully retract the wheels; but the covers will be held in place flush against the hull by tabs 104, which are moulded into the hull for this purpose. Alternatively, tabs 104 may be moulded into the covers. Linkages 182 collapse for storage, as shown on the right hand side of the Figure.
It will be appreciated that further modifications to the suspension layout described above may be made as required without departing from the spirit and scope of the invention. For example, the covers described may be applied to a non-driven, and/or a steered, axle. Rather than the lower suspension members being tubular, they may be solid, or wishbones. eee -.e . - .--. . - - ë ë
