Definitions
- MULTI-PURPOSE SUSPENSION SYSTEM This invention relates to a suspension system for improving the static or dynamic stability of bodies which rest on or move over land or water or which move through the air and is particularly, though not exclusively, applicable to the passenger, freight or luggage compartment of land, air and water vehicles and to those parts of building structures which extend above the ground, all of which will be hereinafter referred to as bodies- Rigid bodies of the kind referred to may, dependent upon their location and purpose, be subjected to a variety of shocks caused, among other things, by waves, uneven ground, earth tremors, or air turbulence and it is a principal object of the invention to minimise the effect of these or other phenomena on a wide variety of bodies by breaking down the usual monolithic structure having a single centre of gravity into a complex arrangement of separate masses each having its own centre of gravity and being independently connected to at least one of the other masses to permit relative movement of one with respect to the others.
- a suspension system for resiliently mounting a rigid body on a rigid base assembly comprises an intermediate frame, spring-supported from said base assembly for limited relative angular movement about an axis vertically aligned with the central longitudinal axis of the base assembly and supporting said body for limited horizontal and vertical movement relative thereto and arm means pivotally mounted on at least one end of said base assembly for limited angular movement relative thereto about an axis parallel with the axis of rotation of said intermediate frame, said arm means being connected to opposite sides of said body.
- Figure 1 is an exploded perspective view of a vehicle suspension system in accordance with a first embodiment of the invention, which may employ semi-elliptical leaf springs or coil springs;

- Figure 11 is a perspective view, on an enlarged scale, of a cross-linkage to be employed with the split type axle shown in Figs. 8 and 9.
- a vehicle chassis/body structure 10 supporting means in the form of front 14 and rear 16 tyred road wheels, mounted on respective axles 18, 20, and a suspension system interposed between the support means and the body structure 10.
- the suspension system comprises an intermediate frame 22 having opposed pairs of lateral arms 26, 28, 30, 32, each arm 26, 28, 30, 32 being pivotably mounted at one end on a respective pin 34, 36, 38, 40.
- the other end of each arm 26, 28, 30, 32 is slidably attached to respective cross linkages 42, 44, 46, 48 provided at each of the four corners of the frame 22 .
- Further arms 50 and 54 are provided at the front and rear ends, respectively, of the frame 22 and are pivotably mounted on the ends of body structure 10 by means of pins 58, 60 which lie on the longitudinal centre line (12) of the body structure 10.
- the opposite ends of the front and rear arms 50, and 54, respectively, are slidably attached to respective cross linkages 42, 44 and 46, 48. Stops 49 are provided on the arms 50 and 54, at both sides of cross-links 42, 44, 46, 48 to limit radial motion of the vehicle body structure 10.
- Front road wheels 14 mounted on axle 18 are urged downward by coil springs 62 interposed between the axle 18 and the frame 22.
- The.coil springs 62 are attached at their upper ends to the lateral arms 26, 28 of the frame 22 and at their lower ends to the axle 18.
- Rear road wheels 6 mounted on the axle 20 are urged downward by semi-el1iptic leaf springs 64 interposed between the axle 20 and the frame 22.
- U bolts 66 fix the leaf springs 64 to the axle 20 and the leaf springs 64 are pivotably mounted at both ends on the frame 22 by means of shackles 68 which are pivotably mounted on the lateral arms 30, 32, of the frame 22 (see Figures 1 and 5).
- pivotably mounted shackles 68 permits greater movement of the leaf springs 64 relative to the body structure 10 and enables the arms 78, described hereinafter, to be omitted.
- the front coil springs 62 may be replaced by semi- elliptical leaf springs attached in the same manner as the rear springs 64 ' .
- Arm means 70, 72 are mounted for rotation at the centre of the front 18 and rear 20 axles on pins 71 and 73 respectively, the axes of which coincide with the central vertical axis of the body structure assembly, at both the front and rear ends.
- the arm means 70, 72 each have respective right 70A 72A and left 70B, 72B pivoted extensions extending to the body structure 10 and pivotably mounted on brackets 74 on said body structure.
- the arm means 70, 72 and their extensions limit or control body roll when the vehicle is driven around bends, during braking or when being driven over uneven surfaces.
- a pair of arms 76 is pivotably mounted at one end on each of the axles 18, 20 and a pair of arms 78 is pivotably mounted at one end and at a different level to the arms 76 only on the or each axle to which coil springs 62 are attached.
- the arms ' 76, 78 are pivotably mounted at their other ends on the body 10 and contribute to the control of the radial motion of the body during cornering, and to the forward motion of the body during braking (see Figs. 2 and 3).
- body structure 10 is formed with ports 82 to receive piston means 80, bedding on springs 81, held in position on the body structure by holder 83. Both piston means at the left and right side of the body structure are connected together at 80A for simultaneous movement.
- the piston means 80 when operating media is supplied to the spaces above the pistons, will raise the body structure 10 to a higher level relative to the ground and serve to absorb or regulate shocks which tend to disturb the wheels 14, 16 and the comfortable ride of the vehicle body structure 10.
- the system provides the further advantages of higher axle displacement, improved shock absorbtion and at least two further free motions within its system, namely vertical up and down motion of the bod structure relative to the ground.
- any suitable media e.g. pressurised fluid, air, hydraulic fluid or any combinations thereof can be supplied to ports 82.
- Figures 4, 5, 6 and 7 illustrate the inventive principle as applied, for example, to a land vehicle, the main units.of which comprise the body structure 10; the intermediate frame ' 22 (shown in broken lines in Fig. 6) including arms 26, 28, 30, 32 and cross sliding links 42, 44, 46, 48, coil springs 62 or semi-elliptical leaf springs 64, or a combination thereof, as shown in Fig. 5; arm means 70, 72 centrally mounted on the axles, along with their respective arms 70A, 72A, 70B and 72B pivotably mounted thereon and extending to the side brackets 74 of the body structure; the front and rear axle assemblies 18, 20 respectively, including items 76, 78 being the supporting arms mounted at different levels, and items 14, 16 being the ground supports for the body structure.
- Figure 8 illustrates another application of the invention in which the solid type axle 18 of Fig. 7 may be replaced by a split type axle 84, and wherein the ground support road wheels 14, 16 are replaced by at least one inflatable member 12A for maintaining a body above water level.
- Figure 9 illustrates another application of the invention as applied to the landing gear means of ' a typical aircraft employing one or two axles 84 of the kind shown in Figure 8 and suitable tyred ground wheels 12.
- Figure 10 illustrates another application of the multi-. purpose suspension system, in the form of a prefabricated * building structure having a body structure 10, intermediate frame 22, cross sliding links 42, 44, 46, 48, coil springs 62, centrally mounted arm means 70, 72, with their respective links 70A, 70B, 72A, 72B and brackets 74 fixed to the body structure 10, front and rear axles 18, 20, which may be of the type shown at 84 in Figs 8 and 9 and raising means consisting mainly of piston means 80, ports 82, spring means 81 and spring holders 83, the system providing the improved free motions up to and including twenty four.
- the suspension system described herein is able to control any sideways displacement of the vehicle body allowing the vehicle to be driven over such terrain with comfort and improved stability.
