Title: Limited slip differential
IPC: F16H48/22
Filed: 1965-05-17
Abstract: 1,045,942. Differential gear. ROCKWELL STANDARD CORPORATION. May 17, 1965 [May 22, 1964], No. 20825/65. Heading F2D. A motor-vehicle limited-slip bevel-type differential gear is locked by torque - responsive multi-disc clutch packs 40, 42, biased into engagement by one or more plate springs 74, 76 whenever the output torque on one or other output shaft 22 or 24 vanishes, e.g. when one wheel loses traction. As shown, interleaved clutch discs 54, 46 drivingly connect the differential casing 14 to spacer collars 30, 32 splined on the axle shafts 22, 24. The plate springs 74, 76 act on the clutch packs through a pressure plate 72, thrust washers 70 and clutch retainer plate 68, the clutch packs being supported against axial inward movement by retainer rings 60 secured by socket screws to the casing 14. During normal drive, the axially outward thrust of the side wheels 26, 28, due to bevel tooth reaction acts through the spacers 30, 68, 70, 72 to overcome the spring bias, releasing the clutches to permit unrestricted differential action. If either driven wheel loses traction; the driving torque and hence bevel tooth reaction thrust is reduced permitting the plate spring packs to engage the clutch packs to lock the differential gear. The inner clutch discs 46 are splined to the spacer collar 30 which together with the side wheel 26 and retainer plate 68 are splined to the driven shafts 22. A number of splines between the collar 30 and discs 46 are omitted to provide axial passages 48 (Figs. 3 to 5, not shown) for lubricant fed through axial bores 50 in the faces of the side wheels 26 etc., and distributed to the clutch packs by curved grooves 52 on the faces of the inner clutch discs 46 (Fig. 4). The outer clutch discs 54 together with the pressure plate 72 are externally formed with togs 56 which drivingly engage corresponding cast or milled slots 58 in the casing 14. In Figs. 6 and 7 (not shown), the retainer ring 60a is secured in the casing by a circlip 80 instead of screws, also, thrust pins 82 slidable in axial bores in the spacer collars 30a serve to transmit the axial thrust of the side wheels for clutch release.

Abstract: 350,292. Welding. BUDD MANUFACTURING CO., E. G., 2500, Hunting Park Avenue, Philadelphia, U.S.A.-(Assignees of Hanson, A. F. ; 2500, Hunting Park Avenue, Philadelphia, U.S.A.) July 14, 1930, No. 21287. Convention date, Aug. 8, 1929. [Class 83 (iv).] In a welding machine, particularly for flash - welding long seams in metal sheets, e.g. of the order of 100", dies of corresponding length are used, the ends of the movable die being connected by parallel movement mechanism so as to ensure uniform movement thereof. The sheets 12, 13, Fig. 2, are placed on the dies 10, which together with electromagnetic blocks 14, are carried by frames respectively mounted between and secured to fixed and movable pairs of pillars 21, 25, Fig. 1, the sheets being clamped by the parts 17, 18 of armatures 15 controlled by a hoisting mechanism operated by fluid-pressure motors 20. The pillars 25 are each secured to a beam 26 slidable in one of the pillars 21 and also in a support 28. The beams are operated to cause approach of the dies by a pair of hydraulic motors 39 provided with reciprocating cams 35 engaging followers 36 on bell cranks 32 connected by links 33 to the beams. The bell cranks are mounted on a common shaft 41 to form a parallel movement mechanism, so that the beams move in synchronism irrespective of the differential resistance due to varying mechanical and electrical conditions in the machine. The motors are synchronized so that the motor having the lower load helps out that having the higher load. For this purpose the pistons 43 are extended outwardly and are provided with a pair of racks 42 engaging pairs of pinions 43<1> on parallel shafts 44. The movable die is retracted by a pair of fluid-pressure motors 46, the supply of fluid to which is conveyed through check valves 48, which are opened during approach of the dies and are closed for retraction thereof. The fluid for operating the motors passes through small ports 49, Fig. 5, so that the movement of bell cranks lags behind the receding movement of the cams 35 under the action of the reverse movement of the motors 39, so as to release the cams of heavy pressure and permit the motors to retract them quickly to starting position. The motors 39, 46 are both governed from a valve 50 by a lever 51. Gauges 52, 53, Fig. 4, of different thickness are initially inserted between the sheets to position their edges divergently, so as to arrange them suitably for a perfect starting and continuation of the arc. These gauges are mounted on shafts 54 and are moved into position by handles 56 and returned by springs 57.

A fluid-pressure amplifier comprises a valve (10) Fig. 1 (not shown) movable in response to two pressure input signals to control the flow of fluid from chamber (13) to a chamber (14). The chamber (14) has a manually adjustable throttle valve (12) controlling leakage to atmosphere and a signal output (p1). The valve is adjusted by a lever (6) subjected to a pressure (Po) acting on the outside of a bellows (2) and a pressure (po) acting on the inside of a bellows (3). The bellows are constructed with rigid central rings between the corrugations which limit the collapsing movement of the bellows. The pressure supplied to chamber (13) also passes through perforated diaphragms (8) and (9), which support the valve, to a chamber having an outlet port (15) to the atmosphere and this maintains a pressure acting in bellows (2) and outside bellows (3) which is slightly above ambient pressure. The amplifier may be used in an aircraft control system when the pressure (Po) is the total pressure and pressure (po) is the static pressure. In a modification, the valve (21), Fig. 3 (not shown) is moved by a single bellows (20) whose exterior is subjected to the pressure (Po) and whose interior is subjected to a pressure in chamber (C) which is controlled by a valve (26) moved by a bellows (27). The bellows (27) receives the pressure [po) and opens the valve (26) to prevent the pressure in chamber (C) exceeding a value above (po).
