The 3-point chassis suspension enables the engine to be fitted rigidly to the frame, and presumably would reduce the necessity for a subframe. This type of front suspension also permits of a very excellent steering lock being obtained. Farman. One other car with original features of suspension is the Farman. This firm have made an effort to obtain a variable rating rear suspension with leaf springs. The main rear springs are cantilever, very much off-set as indicated. The main leaf has considerably more initial camber than the other leaves, the result being that until this leaf is deflected 1 1/2" approx. from the normal load position, the other leaves do not come into action. An auxiliary transverse spring assists the main leaf in carrying the normal load, and in order to give lateral stability over the conditions of light spring-ing, a stabiliser is fitted between the rear axle and the frame, which presumably prevents rolling. FARMAN REAR SUSPENSION. AXLE CONTROL. On some cars such as the Itala, both the front and rear axles have torque provision for braking by means of shock absorbers. contd :- | ||
