<p>1,124,698. Tandem axles. EATON AXLES Ltd. 18 Nov., 1966 [6 Dec., 1965], No. 51855/66. Heading B7H. [Also in Division F2] A tandem axle assembly comprises an interaxle differential 40 which delivers power to a differential mechanism 45 of a first axle having output shafts 42, 43, and a differential mechanism 35 of a second axle having output shafts 31, 32, the differential 35 being of a full-locking or biasing type which transmits zero or less torque respectively to one output shaft thereof upon rotation relative to the other shaft thereof. The differential 45 is driven from the side gear 60 of differential 40 through gears 55 and 54, shaft 53, pinion gear 52 and ring gear 51. The differential 35 is driven from the side gear 61 of differential 40 through shafts 39 and 38, driving pinion 37 and ring gear 36. A look-out mechanism 80, 81 is associated with differential 40, and this differential is supplied with lubricant by gears 54, 55 which deliver it to a channel in the differential housing before it drains into the differential. A fulllocking differential, Fig. 4, comprises a spider 95 which rotates with ring gear 36 and is provided on opposite faces with driving clutch teeth 96 that engage teeth on two driven clutch members 97. Each member 97 is splined on a sleeve 98 to be axially slidable therealong, the sleeves 98 being in turn spliined on the shafts 31, 32. Cam teeth 105 are formed on a clutchdisengaging member 106 mounted within the spider 95, the member 106 being rotatable relative thereto but prevented from axial movement by a snap-ring 107. The cam teeth 105 engage corresponding teeth 110 on parts 111 of the members 97. The coaction between the cam teeth 105 and 110 is such that when there is relative rotation between shafts 31 and 32, a declutching action is effected of the faster rotating shaft. A pair of coiled springs 103 are provided between sleeve members 98 and spring retainers 104 to bias the teeth 105 and 110 into the clutched condition.</p> |
