The suspension of this car is almost identical with the Cottin-Desgouttes (again relying on grease-gun lubrication for the universal joints) with the exception that (a) lateral stability has been obtained by shock absorbers as described in the patent specification, (b) the axle control has been obtained by the aforementioned shock absorbers and on the rear axle is additionally improved by a flexible strap from the junction of the lowest transverse leaf and the stub axle to a cross member. On the road our impression was that the nett result of providing lateral control, (the car was driven fast round corners without any objectionable rolling) has been to spoil the suspension at low speeds, and even at high speeds, it is definitely inferior in the back seats to the rear of the Lancia. The brakes are quite effective. The only impressive demonstration the driver was able to put up was to mount a high curb with the N.S. wheels: under these circumstances the behaviour of the car was remarkably good. 10-HP Ansaldo. This car, which is the latest product of the firm has a transverse front leaf spring attached to the centre of the chassis by a trunnion bearing. The support for the trunnion bearing is carried to the rear of the gearbox as in the sketch. The whole chassis is therefore 3-point suspended. The axle control is provided by a torque arm as in the Ford, Austin-7, and others. No shock absorbers were fitted. contd :- | ||
