Title: Hydraulic ratio changing system for an automatic transmission
IPC: F16H61/06
Filed: 1973-02-27
Abstract: 1365036 Change-speed control VOITH GETRIEBE KG 27 Feb 1973 [29 Feb 1972] 9558/73 Heading F2D In an automatic transmission having hydraulically actuated friction elements for selecting different ratios, and control means for reducing the pressure of the hydraulic medium during ratio shifts, timing means is provided for each different ratio shift to determine the periods during which the pressure is reduced. In one embodiment, a hydraulic pump 10 supplies fluid to actuating pistons (not shown) for the friction elements through onoff valves 15 controlled by a device 14 governed by a gear selector lever (not shown) or by output speed and the setting of an engine fuel control 29. The reduction of pressure during ratio shifts is effected by an electromagnet 24 which acts on the spool of a pressure relief valve 20, or on its loading spring 22, and the duration of energization of the electromagnet is determined by a monostable multi-vibrator for each ratio shift, the multi-vibrators 12 and 23 being effective for shifts from first to second and second to third ratios, respectively, and the multi-vibrators 32, 21 being effective during downward shifts. One of these multi-vibrators may be used also for shifts between neutral and first and reverse, or additional multi-vibrators may be provided. The force applied by the electromagnet, and therefore the degree of pressure reduction achieved, is adjusted in accordance with the position of the fuel control 29 by signals fed to the multi-vibrators from a transducer 28 and amplifier 27. In a modification, the adjustment of the valve 25 to reduce pressure is effected by a hydraulic loading under the control of a further valve governed by the multi-vibrators, and the rate of restoration of normal pressure is controlled by a spring- loaded hydraulic accumulator discharging through an orifice.

In a combination lock of the kind in which a permutation device is disposed in the path, towards the latch, of an operating rod 106 trunnioned axially within the housing 101 of the lock and axially shiftable therein, the permutation device consists of a number of discshaped tumblers 108, 109, of different diameters coaxially disposed with respect to the operating rod 106 and having each a peripheral clearance 122, 123, and of a pressure disc 124 slidably mounted on the operating rod 106 and carrying a number of fingers 126, 127, each of which corresponds to a clearance of the tumblers and is adapted to pass freely therethrough after the tumblers have been successively brought, by means of the operating rod, in their radial position of adjustment in which the clearance in each of the tumblers is in alignment with the associated finger. As shown, the lock comprises a rear-plate ring 111 provided with a flange 112 which with a rear cover 105 of the housing 101 houses the disc 109 ; a channel section plate ring 113 having an internal flange, which with the ring 111 houses the disc 108, and a pair of rings 115, 116. All the rings except ring 115 are integrally connected by bolts 110. An end ring 120 is disposed between the ring 116 and a rotary dial 104 which co-operates with a pointer on a flange 121 of the housing 101. The rod 106 is guided on a tube 128 integral with the dial 104 and the tube 128 is provided with three slots 129 for a lug 107 and three thrust arms 130, all integral with the rod 106. Each of the discs 108, 109 is made of a central hub part 131, Fig. 6, having a passage 132 for the tube 128 and a ring part 133 having the clearance 122 or 123. The ring part is adjustable on the hub by means of a set-screw for setting a particular combination. In operation, the rod 106 is rotated to bring the clearance 122 of disc 108 in line with finger 126, to allow the rod to be pushed up to disc 109 and to be rotated until lug 107 engages a notch 135 on disc 109. The notch 135 is formed with sloping edge portions and to facilitate engagement of the lug 107 therewith. The disc 109 is then rotated and the rod pushed inwardly to engage the fingers 126, 127 in the clearances 122, 123 and to free the lug 107 from the disc 109 and to permit the rod to engage and unlock the bolt. When the rod is disengaged and rotated anticlockwise, the lug 107 engages the notch 135 during which motion the disc 124 disengages the fingers 126, 127.
