Title: Improvements in or relating to resilient mountings
Inventor: HIRST ARCHIE JOHN
IPC: B60K5/12
Filed: 1952-08-21
Abstract: 732,713. Resilient mountings. METALASTIK, Ltd. Aug. 20, 1953 [Aug. 21, 1952], No. 20986/52. Class 108 (3). A negative stiffness spring comprises a rubber strut 18 (Fig. 3) arranged under compression between a fixed part 10 and a part 24 movable in a direction inclined to the axis of the strut, so that upon a deflection to either side of the normal position (shown) of the strut, which, due to its compression, is in an unstable condition, a force away from the normal position is exerted upon the movable part. In the construction shown in Fig. 3, the part 24 is connected to a second rubber strut 19. The struts 18, 19 are bonded at their ends to circular rods or tubes 27-30, but may be bonded to flat plates fixed to the parts 10 or 24. In a modification (Fig. 1, not shown) the struts 18, 19 are each in the form of conventional compression springs built up from circular rubber discs with interposed rigid spacing discs. The end-plates of each spring in this construction are pivotally connected respectively, to the parts 10, 24. In Fig. 5, a single rubber strut 34 (corresponding to 19 in Fig. 3) is disposed in series with a conventional rubber shear spring 33. The terminal member 35 at one end of the strut 34 is rigidly connected with the member 32 at the outer end of the shear spring 33. The member 31 common to the spring 33 and the strut 34 may be connected to the engine of a motor vehicle, the member 32 being rigid with the vehicle chassis. The compression present in the spring 33 is insufficient to prevent this spring functioning primarily in shear. For limited deflection either upwardly or downwardly from the normal position shown in Fig. 5, the negative stiffness of the strut 34 results in a reduced stiffness of the mounting as a whole. The load-deflection characteristic of the mounting is thus S-shaped.
