Abstract

1,149,124. Differential gearing. VAUXHALL MOTORS Ltd. 18 Jan., 1968 [7 Feb., 1967], No. 5915/67. Heading F2D. In a differential gear, particularly for a motor vehicle, slip is resisted by pumping hydraulic fluid through one of two restricted orifices according to the direction of rotation of the output gears. In the embodiment shown in Figs. 1 and 2, a pair of bevel gears 16, 18 carried by a driven casing 10 mesh with output gears 20, 22 on shafts 24, 26. Shaft 24 carries a ring of gear teeth 28 arranged eccentrically with respect to a ring of internal gear teeth 30 which rotate in casing 10 to form a pump in conjunction with an arcuate member 32. Passages 36, 38 lead from the pump to chambers 40, 42 each of which has a pair of apertures controlled by spring-loaded intake and relief valves 44, 48 respectively, valves 44 having restricted delivery orifices 46. Whenever there is relative rotary movement between shaft 24 and casing 10, fluid is drawn in through one of the apertures 46 and its associated valve 44 and pumped out through the other aperture which produces a resistance to the flow of fluid increasing with the speed of relative rotary movement. Relief valves 48 prevent too great an increase in hydraulic pressure. Alternatively, the pump may be of the vane or plunger type. Fig. 6 shows another embodiment wherein the differential is of the type having three pairs of planetary gears 50, 52, the gears of each pair overlapping and meshing with each other and with the output gears. The gears together form a total of nine gear pumps communicating by passages 56, 58 in casing 10 with the chambers 40, 42.
