Abstract
An amphibious vehicle has retractable road wheels to allow planing over water. Power to the road wheels is disconnected automatically as the wheels are retracted. This may be achieved through a cable attached to a suspension rocker arm to disconnect a dog clutch attached to the input shaft of a differential as the wheels are retracted; and vice versa. The system may be fitted to a steered axle or to any suitable retractable suspension system.
Description
- This application claims priority from Great Britain Application Serial No. 0423517.2, filed Oct. 22, 2004.
- The present invention relates to transmission arrangements for amphibious vehicles, and in particular to control aspects thereof.
- It is known for amphibious vehicles to have road wheels which can be retracted above the water line for use of the vehicle on water. This has the advantage of reducing hydrodynamic drag; particularly where the vehicle is designed to plane over the surface of the water, as such vehicles travel faster than displacement vehicles.
- Where such wheel retraction systems are fitted, and the road drive and marine drive are driven in parallel, for example as disclosed in the applicant's co-pending application published as WO 02/07999, it is preferable to disconnect road drive on water. An example of road drive disconnection is disclosed in WO 02/14092, also of the present applicant. In this disclosure, a decoupler is provided in each wheel driveshaft. Such decouplers have many virtues, but light weight and simplicity are not among them.
- It is advantageous if a single decoupler can be arranged to decouple drive to both wheels. This could be achieved by situating the single decoupler, for example, on the input driveshaft of the differential, where a single driven axle is provided. However, the location of the decoupler is not a solution to the problem of excess weight and complexity; the decoupler still needs to be activated.
- Since there are a number of adjustments to be made to an amphibious vehicle during mode change on entry into or egress from water, it is preferable to reduce as far as possible the number of tasks that have to be effected directly by the driver. This helps simplify control of the vehicle at a critical time, one which is not necessarily intuitive to the novice amphibian driver. Accordingly, the present invention provides for automatic decoupling of road drive when the wheels are retracted during mode change from land mode to marine mode and for automatic coupling of road drive when the wheels are protracted during mode change from marine mode to land mode.
- In a first aspect, the present invention provides an amphibious vehicle comprising:
-
- a prime mover;
- land propulsion means;
- marine propulsion means;
- transmission means for transmitting power generated by the prime mover to the land and/or marine propulsion means; and
- retractable suspension means capable of retracting and protracting the land propulsion means, wherein:
- the land propulsion means is automatically decoupled by the transmission means when retracted by the retractable suspension means.
- In a further aspect the amphibious vehicle comprises a body; a power train comprising a prime mover, a road transmission, and a marine transmission; and a suspension capable of retracting road wheels; where the road transmission is decoupled automatically as the road wheels are retracted.
- The road wheels may drive at least one tracked drive.
- The road transmission may be decoupled at a differential input.
- The decoupling means may be a dog clutch.
- The decoupling means may be mechanically linked to the retractable suspension; particularly by a push-pull cable.
- A spring return means may be fitted to the actuator for the decoupling means.
- These and other features and advantages of the present invention will become apparent from the following detailed description of preferred embodiments which, taken in conjunction with the accompanying drawings, illustrate by way of example the principles of the invention.

FIG. 6 is a transverse elevation view along plane VI-VI inFIG. 1 , of a rear axle of the vehicle ofFIG. 1 . - As can be seen from
FIG. 1 , amphibious vehicle 2 has aprime mover 4 driving ajet drive 6 through a marine transmission, described below with reference toFIG. 2 . Road traction is provided bywheels 8, which are driven through a road transmission. Thewheels 8 are shielded bywheel arches 12. The vehicle body comprises anupper body 14 and ahull 16, which are formed separately and joined atsplit line 18. A chassis is also provided, as is described in further detail below. If this chassis is bonded to or otherwise attached to or integrated with the bodywork, it may be regarded as part of the overall body structure. Thehull 16 has a planingsurface 20. A driver'sseat 22 is provided with one ormore passenger seats 24 situated astern of the driver'sseat 22. The seating axis is coincident with the longitudinal axis of the vehicle 2, or parallel thereto. The axis of theprime mover 4 is also coincident with, or parallel to, the longitudinal axis of the vehicle 2. Driver controls are provided, in this preferred embodiment by virtue ofhandlebars 28. Awindscreen 26 is provided for weather and spray protection. -
FIG. 2 illustrates a perspective view of thevehicle rolling chassis 60 in isolation. A front, steered,axle 40 can be seen to the right; and a rear, powered, non-steeredaxle 50 to the left. Theprime mover 4 may also be seen, mounted longitudinally, and substantially centrally in the vehicle. Numeral 70 denotes a support frame, which will be further described later. -
FIG. 3 is a schematic representation of essential integers of the power train of the vehicle ofFIG. 1 .Prime mover 4 has acrankshaft 38, coupled fixedly to afirst driveshaft 40. Driveshaft 40 is in turn connected to and provides drive to atransfer case 30.Marine driveshaft 5 is also connected to and is driven by thetransfer case 30, to provide power to marine drive means 6, which preferably takes the form of a jet drive. Thetransfer case 30 may incorporate a decoupler or a fixed ratio change for themarine drive 6. A reverse gear may also be provided here for themarine drive 6, to allow for manoeuvring, or for clearance of weed or other debris, etc., from inside the jet drive. -
Transfer case 30 also provides a road transmission output alongvertical output shaft 86. Bevel gears are used to transfer power fromshaft 40 toshaft 86. Thechange speed transmission 32 is shown as a CVT (continuously variable transmission), comprisinginput pulley assembly 90,output pulley assembly 92, and adrive belt 91 connecting the two. The output fromCVT 32 is taken down to differential 34 byvertical output shaft 88. The input to differential 34 is provided through adog clutch 33.Numeral 99 denotes an electric motor, preferably a starter motor with attached Bendix drive. Such a drive may be used to provide a reverse gear wheretransfer case 30 does not provide such a facility. -
FIGS. 4 a, 4 b, 5 a, and 5 b illustrate the retractable suspension assembly of one axle of the vehicle ofFIG. 1 in isolation, to more clearly show how the present invention works.Retraction device 242, preferably ahydraulic cylinder 244 including arod 246, is pivotally connected to the vehicle chassis (not shown) at mountingpoint 250. This mounting point may be on a support frame, such asitem 70 inFIG. 2 . The distal end ofrod 246 is fixed to apivot 248, to which there is also fixed arocker arm 232, with acentral pivot 240. Each end ofrocker arm 232 has apivot 234, to which is connected awheel suspension assembly 224, comprising acoil spring 226 and atelescopic damper 228 with apush rod 230. A push-pull cable assembly 310, comprising anouter cable 316 and aninner cable 312, is fixed to the vehicle chassis at mounting 318; and to therocker arm 232 at mountingpoint 314. The distal end of eachsuspension assembly 224 is pivotably linked to alink arm 220. These linkarms 220 are in turn linked torespective torsion tubes link arms 220 andtorsion tubes similar members 216′, 218′ can be seen from another perspective inFIG. 7 . - For a driven axle, as shown,
torsion tubes lower suspension arms 214 which enclose driveshafts (not shown).Upper suspension members 215 are also provided, mounted to be swingable aboutinner pivots 213.Wheel hubs 204 are mounted to the distal ends oflower suspension arms 214. - As can be seen in
FIG. 5 a, whenram 244 is retracted, itsrod 246 is retracted into the cylinder ofram 244.Rocker arm 232 is therefore rotated (clockwise, as shown) aboutpivot 240. This pullssuspension assemblies 224 in towards the centre of the vehicle 2, rotatinglink arms 220 andtorsion tubes lower suspension arms 214 upwards.Wheel hubs 204 are thus also rotated upwards, raising the road wheels (not shown) clear of the surface of the water, even when the vehicle 2 is banked in turns when the vehicle 2 is operated over water. It can also be seen fromFIG. 5 a, that the geometry of this system is such thatupper suspension members 215 fold up beyond a vertical position, so that their inboard ends are now inboard ofpivots 213. - As this wheel assembly retraction process takes place, it can be seen through comparison of
FIGS. 4 a, 4 b and 5 a, 5 b thatinner cable 312 is pulled through the outer cable 316 (which is fixed in position at mounting 318). As can best be seen fromFIG. 5 b, this in turn allowscable assembly 310 to disengage dog clutch 33 (located above differential 34), thus achieving the object of automatically disconnecting road drive towheels 8 as said wheel assemblies are retracted by the retractable suspension. The reverse process will of course also apply, so that road drive is automatically reconnected as said wheel assemblies are protracted, from theFIGS. 5 a, 5 b situation to that shown inFIGS. 4 a, 4 b. A spring 320 (shown inFIGS. 4 b, 5 b) may be fitted tocable assembly 310 as a safeguard, to ensure a failsafe condition (if the cable snaps) in which the clutch 33 is closed. Also thespring 320 acts to keep thecable 312 in tension; the clutch 33 is opened against a biasing force applied by thespring 320. The spring stores energy which is subsequently used to shut the clutch 33 when the movement ofrotor 232 allows the cable to slide to permit rotation ofarm 325. - The term “dog clutch” is often used in the art to describe a sprag engaging on a ratchet type wheel. Such a clutch has the known weakness of only being able to transmit power in a single rotational direction; any attempt to transmit power in the reverse direction will simply snap the sprag clutch arm. As can be seen from
FIGS. 4 b and 5 b, however, thedog clutch 33 used in the present invention has twogear wheels teeth 332 of substantially square profile; and can therefore transmit power equally well in both directions. Furthermore, thebevel gear 335 shown engaging and disengaging with thedog clutch 33 must be free to rotate on thehorizontal shaft 336. Were it to be keyed toshaft 336, drive to the road wheels would be permanently engaged. On the other hand, the dogclutch sliding gear 330 must be splined to theshaft 336. As can be seen fromFIG. 4 b, anarm 325 is used to relay the motion of the dog clutch end ofcable assembly 310. -
FIG. 6 shows a view from in front of the rear axle of the vehicle ofFIG. 1 , to illustrate the spatial relationship ofcable assembly 310,dog clutch 33, and differential 34. - It will be appreciated that further modifications to the transmission layout described above may be made as required without departing from the scope of the invention. For example, other suspension retraction mechanisms may pull the push-pull cable equally well (e.g. directly acting hydraulic or pneumatic cylinder(s), electric motor(s) or linkage mechanism(s). A dog clutch could be applied to one or both differential output shafts, rather than to the input shaft; the entire arrangement could also be applied to an axle which is both powered and steered. Furthermore, rather than the lower suspension members being tubular, they may be solid, or may take the form of wishbones.
- While a particular form of the present invention has been illustrated and described, it will be apparent to those skilled in the art that various modifications can be made without departing from the spirit and the scope of the present invention. Accordingly, it is not intended that the invention be limited except by the appended claims.
