[Classes 108 (ii) and 108 (iii)] In a springing arrangement for vehicles &c. with independent wheels using rubber members stressed mainly in shear arranged in the pivot joint of the lever, the rubber members are constructed as strips parallel to the axis of rotation of the lever and extend at both sides symmetrically to the plane of oscillation of the lever. As shown a half axle 9 or lever carrying an independently sprung wheel is connected to a central box girder 6 by rubber strips 2 arranged transversely to the plane of swinging of the lever 9. The strips 2 are attached to plates 4, 3 secured by bolts 5, 5 to a jaw 8 at the end of the lever 9 and a box-shaped bracket 11 secured to the girder 6 respectively. A stirrup 32 at each side of the jaw 8 is provided with a tongue 31 projecting into the end of the bracket 11 and interposed between two rubber blocks 30 which resist in torsion the springing of the lever 9. An additional bent arm 35 at right-angles to the stirrup 32 may engage a rubber block 33 attached to the end of the bracket 11 to resist in shear the springing movements of the lever 9. The position of the arm relatively to the horizontal may be adjusted by screws 13 bearing on the rubber blocks 2. In Fig. 7 the lever 9 is provided at the end with a transverse tubular member 38 through which passes a triangular tube 3 attached at its ends to brackets 42 on the box-girder 6. Rubber strips 2 attached to the triangular tube 3 and plates 4 are secured to the tube 38 by bolts 5 engaging metal strips 37. |
