Abstract

390,835. Motor vehicle axles and driving - gearing. THORNYCROFT & CO., Ltd., J. I., Thornycroft House, Smith Square, London, and BARFORD, V. G., Motor Vehicle & Engine Works, Basing- stoke, Hampshire. Oct. 7, 1931, No. 27860. [Classes 79 (ii) and 79 (iv).] An axle casing 3, of the kind which encloses a hollow circular axle shaft 1 and is of rectangular cross section with its larger dimension arranged horizontally, is, toward one end, enlarged in opposite directions at 3a and provided with co-axial holes in its upper and lower sides so as to form a housing for a gear-box 5, 5a containing the differential gearing and worm gearing driving the axle shaft. In the construction shown the enlargement 3a and gearbox are circular, and the gear-box, which is in two parts, is secured to the axle casing by bolts 22, 24b. A packing ring 25 of cork or other soft material and a ring 23 surrounds the upper part of the gear-box and are secured by studs 24, the coacting surfaces of the two rings being conical. The ring 25 of soft material tends to lessen the transmission of noise or vibration from the gear-box to the axle casing. The lower part of the gear-box is formed as an oil container, and may be ribbed at 5c to assist cooling. The differential gear comprises a spherical housing 12 mounted in bearings 11 in cups 10 formed on the gear-box, the bevel differential pinions having spherical surfaces to correspond with the housing. The cups 10 have cylindrical recesses with concave ends 30a, and packing rings 31 of soft material are pressed against these ends by springs 33 and metal rings 32. The differential housing 12 is made in two parts secured together and to the worm wheel 13 by bolts 29, the outer periphery of the housing and the inner periphery of the worm wheel being correspondingly stepped, so that the resistance of the bolts 29 to shear is increased. Specification 377,928, [Group XXXII] is referred to.
