<p>1,230,118. Differential gear. BORG-WARNER CORP. 6 Nov., 1968 [30 Nov., 1967], No. 52642/68. Heading F2D. In a motor vehicle limited slip bevel-type differential gear, wherein differential rotation of the usual half-shafts 20, 21 is resisted by multi-disc clutch packs 55, or cone friction clutches (155), Fig. 7 (not shown), arranged between side-wheels 43 and the differential casing halves 19, 23 and loaded by springs 81 reinforced by the bevel tooth reaction separating force, the clutch discs 70, 75 of the packs 55 are lubricated via passages 84, in the sidewheels 43, filled by oil deflecting scoops 90, 91 on the clutch spring retainer 80 which collects oil fed into the casing from an outer housing (not shown) via a port 33, the oil centrifugally flowing radially across the clutch discs on exhausting via outlet ports 98 back to the outer housing (not shown). In Figs. 7 to 10 (not shown), the clutch cone surfaces (210, 212) are lubricated from reservoir channels (215), in the casing halves (123), filled by oil deflecting tabs (240) formed on the clutch spring retainer (180) and located opposite the reservoir channels (215), the clutch spring retainer collecting oil fed into the casing halves (123) from an outer housing (not shown) as before, the lubricant being distributed over the clutch cone surfaces via threaded oil grooves (213). In Fig. 10 (not shown), the oil deflecting tab (240A) wholly extends from one side of the spring retainer (180).</p> |
