IPC: F16F1/52
Filed: 1967-11-16
Abstract: 1,251,328. Rail vehicle suspensions; tandem axle suspensions. METALASTIK Ltd. 4 Nov., 1968 [16 Nov., 1967], No. 52109/67. Headings B7D and B7L. [Also in Division F2] A resilient mounting element (see Division F2) employs an annular elastomeric body 64, Fig. 4, located between and bonded to inner and outer rigid members 67, 68 so as to be stressed in combined shear and compression when the element is loaded in the direction A. At least one (as shown both) of the rigid members has a coniform surface bonded to the elastomer, but an end portion 83 of the elastomer is unbonded and spaced from at least one of the rigid members in the unloaded state of the element. In Fig. 4, the right-hand half of the drawing shows the loaded and the left-hand half the unloaded state. The overall characteristic is a spring rate increasing progressively with load, following, e.g., a square law force-displacement plot (Fig. 2, not shown). Fig. 6 shows a road vehicle suspensionthough this suspension system is stated to be applicable to rail vehicles also. In Fig. 6, 60 is an element of the form shown in Fig. 4 and it acts between the longitudinal beam 92 and the load-bearing platform 95. The beam 92 may be rigid as shown or take the form of a leaf spring. The suspension system is such that even when the wheels 90 are on uneven ground the load platform 95 is maintained horizontal, as shown diagrammatically in Fig. 11.

Abstract: 1,251,637. Measuring wheel toe electrically. HUNTER ENG., CO. Feb. 3, 1970 [March 27, 1969], No. 5085/70. Heading G1N. Apparatus for measuring vehicle wheel alignment comprises a platform 10 Fig. 1 carrying two wheel rotating assemblies 11, 12 for the left and right steerable wheels of a vehicle, each comprising a roller 36 driven by a motor 37 and a freely rotatable roller 35, the assemblies being mounted on cradles 18 which are articulated and hinged to provide angular movement in response to toe in and tyre pull forces to produce corresponding displacements of the sliders of potentiometers in housings 41, thereby developing electrical signals which are combined to determine the toe in and tyre pull. The signal voltages on the measuring potentiometers are fed by leads 54, 56 to a first network 65 Fig. 5. With motor 37 rotating in the forward direction, switch 60 is closed to energize relays K1 K2 and capacitors 75, 77 are each charged to the difference between the two signal voltages, i. e. the total toe in of the wheels. Switch 60 is opened, motor 37 is reversed by operating switch 68A, switch 60 is again closed to energize relay K2 only and capacitor 77 is charged to the new toe in signal. When switch 60 is opened the sum of the charges on capacitors 75, 77 is fed to meter 55 which therefore indicates the average of the forward and reverse toe signals, i.e. the true toe angle. The potentiometer signal voltages are also  fed by leads 63, 64 to networks 66, 67 Fig. 6 and the testing procedure of the previous paragraph charges capacitors 88, 89 to the toe signals when the left wheel is driven forward and reverse respectively. Meter 91 indicates their difference, which represents the tyre pull for the left wheel. Similarly meter 102 indicates tyre pull for the right wheel.
