摘要： An electrohydraulic transmission shifting apparatus includes an electrohydraulic transducer with a throttle valve operated by an electromagnet and a pressure-limiting valve which effects a kickdown signal at a predetermined maximum pressure when the gas pedal is fully depressed. Fluid under pressure is supplied from a pump to the valves. A fluid-pressure control flow, limited by the pressure-limiting valve, is supplied to a main valve connecting a pump with the shifting means of a transmission so that the valve operates in accordance with the control flow. The pump is also connected with the kick-down shifting means of the transmission by a kick-down valve when the electrohydraulic transducer is operated upon a kick-down gas pedal operation.

摘要： A kickdown arrangement for the hydraulic transmission of a motorcar includes an electrohydraulic transducer with a throttle valve operated by an electromagnet, and a control valve controlled by pressure fluid from the throttle valve, and producing a hydraulic kickdown signal when a predetermined maximum control pressure is reached upon full depression of the gas pedal. Both valves receive fluid under pressure from the outlet of a pump driven by the motor which drives the transmission. A servo main valve connects the outlet of the pump with the hydraulic transmission, and is controlled by a control flow from the outlet of the throttle valve.

摘要： To permit continued operation of an electronically controlled gear change transmission in case of failure of electronic control signals, at least one three-way check valve is included in the system to connect, in one mode of operation, the normal output control signals from a hydraulic control valve system to engage an operating element (such as a control clutch, control band, or the like in the automatic transmission) and, when in another position, connect hydraulic pressure to effect connection of drive power to the first gear, or reverse (as selected by a control selector) and in the absence of electrical command signals from the electronic control unit. By use of a second three-way check valve, simple interlocks to prevent shifting into reverse when the vehicle is moving forward in excess of a given speed, and to permit holding of an engaged gear in case of malfunction, can be provided.

摘要： A pump, driven by the engine, supplies hydraulic pressure as a function of engine speed; the engine controller provides a displacement force, for example by a cam, acting on a main valve slider, or spool of the switching pressure controller. To additionally provide a speed signal to the main spool, the switching pressure line, connected to the pump, has a Venturi, diaphragm, bent tube, or other constriction therein from which a hydraulic signal representative of engine speed can be derived, which hydraulic signal is applied as a force additionally acting on the main valve slider or spool so that the spool position, and hence output switching pressure, will be representative both of engine controller position as well as of engine speed.
