Patent GB-326342-A (GB)
Title: Improvements in shock absorbers or vehicle spring controllers
IPC: F16F7/04
Filed: 1929-03-04
Abstract: 326,342. Lansing, R. P. March 4, 1929. Vibration - dampers. - In vehicle shock-absorbers adapted to exert greater resistance to the rebound of the vehicle springs than to their compression, a number of friction discs are pressed together, when required, by a spring which acts through screw and cam mechanism in such a way as to obtain a one-way effect and also vary the pressure on the discs according to the displacements due to road shocks. In the construction shown in Figs. 1 and 4, the parts connected to the operating-arm 12 oscillate on a fixed tubular spindle 2 secured to and projecting outwards from the base 1 which is bolted to the frame of the vehicle. The arm 12 is riveted to a ring 15 with internal teeth adapted to engage corresponding teeth 11 on the outside of a cup-shaped member or casing 3 having an inner plate 4 rotatably mounted on the spindle 2. The teeth 11 are closely pitched so that the arm 12 may be given fine angular adjustments on the casing. Splines 25 carried by the casing 3 engage friction discs which alternate with other discs engaging splines 30, the inner ends of which are secured in a pressure plate 31. The central aperture of the plate 31 is mounted by means of screw threads of steep pitch on an actuator 34 having splines which prevent its rotation relatively to the spindle 2. When the arm 12 is rotated in one direction, the pressure plate 31 moves outwardly until it engages a shoulder on the actuator 34; it then forces the friction discs outwardly against the pressure abutment plate 37 which is moved outwardly away from contact with the spacing ring 41. When this occurs, the helical spring disposed in the hollow spindle 2 applies pressure to the disc through the central bolt 48, adjusting-nut 47, and cam mechanism 62, 64. One set of cams 64 is held against rotation relatively to the tubular spindle 2 while the other set 62 turns with the pressure abutmentplate 37 and the operating-arm 12. The pressure exerted by the spring on the friction discs is thus varied by the cam gearing according to the displacement of the operating-arm 12. While movements of the operating-arm in one direction apply pressure to the friction discs as previously described, movement of the arm in the opposite direction reduces the pressure and then allows practically free movement, the pressure plate 31 then moving inwardly towards the base 1 on its screw mounting. In a modification the cam mechanism is disposed between the inner end of the tubular spindle 2 and the actuator 34.
