    摘要: A device for the assisted control of two braking or declutching circuits having independent master cylinders, especially for automobile vehicles, of the kind comprising an operating pedal, at least one master cylinder in which a master piston is adapted to slide under the action of said operating pedal, an assistance cylinder in which slides a piston coupled for movement, at least unidirectionally, to said master piston, means for applying pressures on the two faces of said assistance piston, and a piloting valve which, when at rest, ensures equality of the pressures applied to the two faces of the piston of said assistance cylinder and which, responsive to the movement of said operating pedal, ensures an unbalance between said pressures so as to permit the piston of said assitance cylinder to act on said master piston. In this device, each of said braking circuits is associated with an independent master cylinder arranged parallel to the master cylinder of the other braking circuit, the assistance cylinder being disposed between said brake pedal and said master cylinders, a distribution compensating bar is provided in said assistance cylinder and is interposed between the master pistons of said master cylinders and the piston of said assistance cylinder, said piloting valve being controlled by a pressure equal to the pressure existing in at least one of said braking circuits.

    摘要: 1,190,088. Epicyclic change-speed gear. SOC. ANON. FRANCAISE DU FERODO. 18 Aug., 1967 [19 Aug., 1966; 26 July, 1967], No. 38135/67. Heading F2D. In a change-speed gear, particularly for automobile vehicles, wherein a four (A-D) element epicyclic gear, having the element C permanently connected to an output 11, provides one Reverse ratio, by coupling the element A to an input 10 and braking the element B, and three Forward ratios, viz.: Low Forward, by coupling the element A to input and braking the element D; Intermediate Forward, by coupling the element B to input and braking the element D; and High Forward, by coupling both the elements A, B to input, the element A is coupled to input via an auxiliary change-speed gear providing subratios in Reverse and Low and High Forward, thus providing, through the whole arrangement, N Reverse ratios and 2N+1 Forward ratios, where N is the number of ratios provided in the auxiliary gear. Auxiliary gear upshift results in upshifts in Reverse and Low Forward but a downshift in High Forward. Where the arrangement permits, a further ratio (overdrive) may be provided by coupling the element B to input and braking the element A. In Fig. 1, the epicyclic gear comprises two sun-ring trains compounded, the elements A, D being comprised by first and second train suns 17, 17 1 respectively, the element B comprising the first train carrier 19 and the second train ring 18 1 , and the element C comprising the first train ring 18 and the second train carrier 19 1 . The element B may be coupled to the input shaft 10 through gears 21, 22, 24, 25 and a clutch M and braked at Far; the element C is fast with the output shaft 11; and the element D may be braked at F av . The auxiliary gear provides two ratios between the input shaft 10 and the element A, viz.: reduction, through gears 21, 22, 27, 28 and a clutch S 1 and direct, through a clutch S 2 . In Fig. 2 (not shown), the input shaft is constituted by the shaft, 23. carrying gears 22, 27, 24. In Fig. 3 (not shown), a brake (F sh ) for the element A (providing overdrive) is housed in a casing partition between the gears 28, 25. In Figs. 4, 5 (not shown), the auxiliary gear respectively provides three and four ratios each ratio being brought in by a corresponding clutch. In Fig. 6 (not shown), the change-speed gear includes a tworatio auxiliary gear and is serially preceded by a fluid coupling or, as described, an hydrodynamic torque converter disposed parallel to the epicyclic gear axis and having a reactor reacting on a one-way detent. The clutch S 1 comprises a small capacity clutch in parallel with a one-way clutch. The clutch S 2 is hydraulically actuated and housed in the converter bell. The brake F av comprises a small capacity brake in parallel with a releasable one-way brake. The output shaft 11 may be stationed by a positive Park lock (65). In Fig. 7, the change-speed gear is serially preceded by an hydrodynamic torque converter 42 and includes a two-ratio auxiliary gear. The epicyclic gear elements A, D are comprised by suns 66, 68 respectively, the element B by a ring 70, and the element C by a carrier geared at 78, 79 to the output shaft and carrying intermeshed planets 67, 69 respectively meshing the sun 66 and the sun and ring 68, 70. The clutch S 1 is housed in the converter bell and comprises a small capacity clutch in parallel with a one-way clutch 77. A positive Park lock is operative on the carrier C. In Fig. 8 (not shown) the arrangement is similar to that of Fig. 7, but inter alia, the carrier is fast on the output shaft and the converter is disposed parallel to the epicyclic gear axis.
