摘要: 972,573. Torsion springs. MINISTER OF NATIONAL DEFENCE H.M.'S CANADIAN GOVERNMENT. Dec. 31, 1962, No. 49180/62. Heading F2S. A torsion bar for a vehicle suspension system comprises first and second pluralities of resilient leaves which are substantially equal length, arranged in contiguous parallel relationship, have central transverse axis the mid-point plurality being disposed on opposite side to plurality. As shown, stacked alternate longitudinally-offset pairs 4, 5; 6, 7 &c., received rectangular sockets 25, formed end mountings 2, 3, closed by plates 29, 29 1 , accommodate thrust bearing blocks 30. Wedge-shaped crossbar support combs 31 located respectively between bevelled longitudinal sides 34 30, corresponding adjacent 25. Bars 37-43, with their ends gaps 33A teeth 33 pair socket extend across width latter so that such as 5 bars 41, 42 abut block 30 abutting 42. The 40, 41 provided flat faces co-operate vertical recess At spring &c. pass through rods Keeper 10, 22 L-shape cross-section along longer 25 bear against extensions bolted mounting 2. similar keeper 13, 49 3. Steel 51, 52 3 upper lower stack leaves, edges 58, Figs. 9, engage outermost rounded sloped backwardly at 56 also curved transversely. ground polished, or peened cut back each one both axis.
