524,943. Motor-vehicle spring-suspensions and frames. GOODRICH CO., B. F. Feb. 10, 1939, No. 4458. Convention date, Feb. 23, 1938. [Class 108 (ii)] [Also in Group XXXI] In a vehicle spring suspension vertical movement of the body relative to the axles is controlled by rubber torsion or other springs which are substantially unaffected by tilting movement of the body, while additional rubber torsion or other springs are provided for cushioning the tilting movement. In the motor-vehicle shown a central frame member 14 is supported upon front wheels 12, 13 and double-tyred rear wheels 10, 11, and the engine 15 and drive 19 are disposed to the rear of the rear axle. The wheels 10, 11 are mounted on semi-axles 22, 23 and are connected by swinging arms 28, 29 to a transverse shaft 30, Fig. 4, between which and a divided sleeve 31b is located an annular torsion bush 31a of rubber. The spring element so formed is mounted within a housing 32 which has an integral housing portion 33 at right-angles thereto adapted to accommodate a second rubber torsion annulus 34b. At the front of the vehicle the wheels 12, 13 are mounted upon a swinging fork 43 connected to a transverse shaft 39, which is torsionally supported in a housing 35, Fig. 3, having also a longitudinal housing portion 37. The central frame member 14 is mounted within the torsion bush 34b and a second bush 36 in the part 37, and directly supports the body 49 by means of brackets 16, 16a, 16b.. In a modification, each of the rear wheels is sprung by means of a pair of swinging arms coacting with torsion bushes respectively forward of and to the rear of the semi-axles; while, in a further modification, suitable for a passenger car, the engine is located at the front of the car and the transmission shaft is disposed within the central frame member.
