<p>1,209,793. Differential gears. EATON AXLES Ltd. 18 Jan., 1968 [27 March, 1967], No. 2881/68. Heading F2D. A differential has a multi-plate friction coupling 70 and a positive clutch 80, 82 in series between the driving bevel planet carrier 52 and a side wheel 54. The coupling friction plates are alternately carried by the carrier 52 and by a sleeve 88 which is splined to an axially slidable clutch sleeve 86 formed with the facial teeth 82. As shown the sleeve 88 is in permanent spline connection with the sleeve 86, but as a modification this connection may be broken on shifting of the clutch sleeve to disengage the clutch teeth 82, 80, in which case the opposed end faces of the splines may be tapered as described in Specification 936,906 to effect an initial clutching action. The clutch sleeve 86 is shifted by mechanism 85 which can be actuated by conventional air, hydraulic, electric or air/ electric shift control systems of the type used for shifting two-speed axle arrangements, and the limited slip differential may be employed in a two-speed axle arrangement. Lubricating.-A lubricant pick-up surface 122 is provided on the planet carrier and is partially immersed in a reservoir 120, lubricant being removed from the surface by a plastics-like non-abrasive director 126 supplying the lubricant via a port 130 to a chamber 132 whence lubricant is supplied to the differential via a port 136 and passages 138 and thence to the coupling discs to lubricate and cool them via passages 148, 150.</p> |
