The vehicle coupling differential has a conventional housing (10) made of two parts (11,12), one of which carries a flange (16) for a gear wheel (17) driven by a drive pinion to drive the housing (10). A hexagonal drive rod (25) is fitted diametrally across the housing. A pair of coupling rings (30) are inside the housing (10) either side of the drive rod (25), which is loosely fitted in V-shaped cutouts (31) in the coupling rings (30). The axle shafts (20) have spliced ends held in the axle muffs (23) connected by clutch plates (46). When one wheel rotates faster than the other, the coupling rings (30) rotate, so that one is forced from the drive rod (25). This allows it to move inwards freeing the clutch and thus the wheel axle, until the wheel speeds return to being equal. |
