Abstract

607,356. Differential gearing; ratchet clutches. LOCHER, H. NEIDHART-. Jan. 31, 1946, No. 3139. Convention date, Oct. 16, 1945. [Class 80 (ii)] The normal action of a motor vehicle differential gear is suspended below a predetermined vehicle speed by an interlock between the side wheels and the rotatable casing which becomes ineffective above that speed. As shown applied to the usual toothed bevel gearing, jamming rollers 19 are mounted in cages 16 between the inner circumferential face of the driving casing 2 and the polygonal rim 20 of the side gears 9, 10. Two semicircular fly-weights 11 pivoted on diametrically opposed pins 12 and connected by tension springs 13 are mounted on each side gear and carry on their outer ends pins 14 engaging radial slots 17 in the cages 16, so that inward movement of the fly-weights below a certain vehicle speed presses the rollers 19 into jamming engagement for one direction of rotation of the driving casing and outward movement of the fly-weights above this speed brings them into a central disengaged position. Circular recesses 15 in the side gears 9, 10 limit the outward movement of the fly-weights and prevent them contacting the driving casing. Adjustable end thrust bearings 21 are provided. The toothed gearing may be replaced by friction gearing comprising smooth surfaced conical side wheels engaging driving planetary balls. The fly-weights may have scissor instead of spring connections, and may move in a radial direction only.
