<p>1526806 Universal joints H HARTZ 15 Sept 1975 [13 Sept 1974] 37841/75 Heading F2U In a universal joint comprising, between an input member 1 and an output member 2, at least one elastic ring 11, 12 between a respective pair of annular discs 5, 6, 7, 8 of which one 5, 7 is connected to the input member 1 and one 6, 8 is connected to the output member 2, friction damping of relative rotary motion is provided between the input and output members 1, 2. In the embodiment shown in Fig. 2 the friction damping is provided by friction rings 13, one between a plate 15 and disc 6 and the other between a plate 15 and a thrust plate 17 fixed to the input member, the plates 15 having an elastic member 16 between them to bias them apart and permit relative angular movement of the axes of rotation of the plates 15. In another embodiment (Fig. 1, not shown) a single friction ring 13 is provided, this acting directly on discs 6 and 7. The elastic rings 11, 12 may be of rubber.</p> |
