摘要： A gear shifting assembly for change-speed transmissions of the type having several shifting members which are actuatable to thereby set the transmission to a desired speed position employs two fluid-operated motors the first of which can move a displacing member into register with a selected shifting member and the second of which thereupon actuates the selected shifting member by way of the displacing member. The admission of a pressurized fluid to and the evacuation of fluid from the cylinders of the motors is regulated by a system of valves which are operated by pressurized fluid or by an electronic control unit.

摘要： A hydraulic system for operating a friction clutch has a cylinder, in an internal passage of which a first piston is displaceable between a rest position and a working position against the action of a biasing element associated with the friction clutch, which action tends to move the first piston to its rest position. A second piston is also displaceable in the passage in the same sense as the first piston between a starting position and an operated position and defines with the first piston at all times a chamber. Pressure fluid is accommodated in this chamber at all times and the chamber communicates with a non-pressurized space via suitable passage means when the second piston is in its starting position.

摘要： A gear shifting assembly for changing the speed positions of transmissions in automotive vehicles has a double-acting gear shifting cylinder receiving oil by way of a directional control valve which is actuatable by oil in dependency on a pressure differential between the cylinder chambers. The directional control valve receives oil from a pump by way of an adapter valve which is controlled by an adjustable pressure regulating valve. The pressure of oil which moves the piston in the double-acting cylinder depends on the selected speed position of transmission and such pressure develops when the piston encounters a resistance to its movement in the cylinder.

摘要： An automatic gear change system for automatically actuating gear shift devices of a stepped change speed gear box of a motorvehicle provided with a clutch means comprises a central control device; means for monitoring input and output speeds of the stepped change-speed gear box during synchronous running of input and output transmission shafts to be coupled to each other; and synchronizing aids for expediting synchronous running of the two transmission shafts. The control device includes a synchronizing circuit arrangement producing digital control signals during super-synchronous, sub-synchronous and substantially synchronous running of the two transmission shafts, and further includes switching logic means comprising digitally operating switching and gating circuits which actuate the synchronizing aids, gear shift devices and the clutch means. The synchronizing circuit arrangement advantageously uses two Schmitt triggers having different response and fallout thresholds.

摘要： An automatic transmission system for use in automotive vehicles wherein the engine shaft drives an output shaft through a medium of a reversing gear and the output shaft carries a disk-shaped clutch element which can drive one flange of a variable-pitch sheave on the output shaft. The sheave forms part of a belt drive the other sheave of which drives one or more wheels. The flanges of the sheave on the output shaft are rotatable relative to the output shaft and are movable axially of the output shaft with and relative to each other by a piston which is reciprocable in a cylinder of the output shaft. A helical spring urges the sheave on the output shaft to a position in which the one flange is disengaged from the clutch element. When the cylinder receives pressurized fluid from a hydraulic regulating unit, the piston causes the one flange to engage the clutch element so that the belt drive rotates the wheel or wheels. A further increase of fluid pressure in the cylinder causes the other flange of the sheave on the output shaft to move toward the one flange and to thus change the speed ratio of the belt drive. The regulating unit has a pressure regulating valve which is controlled by an electromagnet. The latter can be influenced by the speed of the engine shaft, by the position of the gas and/or brake pedal, by the position of the kickdown switch and/or by a device which is actuated when the vehicle travels on a sloping road surface.

摘要： A pressure regulator in which the pressure is regulated as a function of electrical signals applied to an electromagnet. The armature of the electromagnet actuates a membrane which has one side subjected to the pressure to be regulated. Two passages have their connections controlled by the membrane which closes one of the two passages in operation. The armature is guided by an elastic element whereby substantially little friction is encountered.

摘要： An automotive vehicle has an automatic transmission to which fluid is supplied from a source through a control valve having a body which is displaceable to control the flow of the fluid to the load constituted by this tranmission. A plurality of binarily stepped pilot faces are provided on one side of the valve body and the other side is connectable to the source of fluid pressure. A plurality of pressurizable chambers at each of the surfaces are each connected via a respective line to a respective solenoid valve itself connected to the high-pressure side of this system. Binary actuation of these pilot surfaces via the solenoid valves in accordance with motor speed allows the transmission very smoothly to be upshifted and downshifted.
