On some cars such as the Itala, both the front and rear axles have torque provision for braking by means of shock absorbers. * Error - apparently, Beardmores pioneered the scheme. * The Hotchkiss, who we believe originated the idea, have not fitted it on their cars, but instead, fit double Hartfords with a very narrow angle between the arms as illustrated :- This device is noticeable on a large number of chassis such as the Alfa Romeo and it appears to one that though it might resist torsion, it might also, once the car has been braked violently, keep the axle with the pivots leaning forward for a brief period until road shocks allow the springs to restore them to their normal position. NARROW ANGLE BETWEEN DAMPER ARMS. Triangular torque arms, as on the Ford, appear to be gaining ground. On the S.A.R.A., quarter elliptic springs contd :- | ||
