| - 8 - BACK AXLE. (SS.{S. Smith}67-74) Ratio 8/34. Spiral bevels with a four pinion bevel differential. The axle is semi-floating. The differential drive is bolted as a unit to the front face on the axle casing. The drive unit is assembled in a single casting which carries the bevel pinion shaft and the bearing for the inner ends of the axle. The differential housing is a steel casting well ribbed. Roller bearings are fitted at the pinion with a two-row dual purpose ball bearing at opposite end of the shaft. Adjustment for the mesh of the pinion is provided by means of a deep ring nut. The differential pinions are on splines on the axle shaft. Adjustable taper roller bearings are used on each side of the differential cage. Details of gears etc. can be obtained from Experimental Design Department. SHOCK DAMPERS. Luvax type C.M.P.C. BRAKES. Girling type brakes. 14" diameter x 2.150 wide C.I. Drum, well ribbed (3 ribs). See sketch SS.{S. Smith}39. FRAME. (SS.{S. Smith}80, 83) The frame is a box section made up of two 'L' flanges welded together and is stiffened by 5 cross members, two of these acting as engine supports. Thickness of frame members .092, 13 S.W.G. Weight of frame. 324 lbs. 8 ozs. See sketch SS.{S. Smith}80. A number of sketches are available in the Experimental Design Section, which are not of general interest, and have been omitted from this book. BY/Ald.{F. Allwood - Experimental Design} | ||
