摘要： A hydraulic control apparatus for a hydraulically operated vehicular transmission has control valves corresponding to hydraulic engaging elements provided in the transmission. The supply and discharge of hydraulic oil to and from the corresponding hydraulic engaging elements are controlled by the control valves. The hydraulic control apparatus has an oil supply passage which is connected to a hydraulic oil source and into which a throttle is interposed. The oil supply passage is connected to oil passages which are on a downstream side of each of the control valves and which are to be communicated with the hydraulic engaging elements. Check valves are interposed in the oil supply passage to allow for the hydraulic oil flow only from the oil supply passage to the oil passages on the downstream side of each of the control valves.

摘要： The gear ratio of a belt-type continuously variable transmission is changed by increasing or decreasing the hydraulic pressure applied to an oil chamber for a drive pulley by a ratio control valve. A spool of the ratio control valve is driven by a normally opened solenoid valve and a normally closed solenoid valve. In a lower gear ratio range, the gear ratio is controlled by controlling the duty rate of the normally opened solenoid valve, and in a higher gear ratio range, the gear ratio is controlled by controlling the duty rate of the normally closed solenoid valve. When any trouble is generated, the gear ratio is held at an intermediate value by bringing both the duty rates of the normally opened solenoid valve and the normally closed solenoid valve into 0% or 100%. Thus, it is possible to finely control the gear ratio of the belt-type continuously variable transmission and, when any trouble is generated, the gear ratio can be held at the value intermediate between a LOW value and an OD value.

摘要： A hydraulic control system for use in an automatic transmission of a vehicle, wherein the automatic transmission comprises a plurality of engaging devices including a low speed engaging device for achieving a relatively low gear ratio and a high speed engaging device for achieving a relatively high gear ratio. The hydraulic control system comprises a pump for generating a hydraulic pressure; and a selector having a plurality of manually selectable positions, for supplying the hydraulic pressure to a selected engaging device. A plurality of electromagnetic valves corresponding in number to said plurality of engaging devices, are each arranged between a corresponding one of the engaging devices and the selector, for controlling the intensity of the hydraulic pressure supplied from the selector to the corresponding engaging device in accordance with operating conditions of the vehicle. A pressure regulating valve, arranged between the selector and the pump, reduces the hydraulic pressure supplied from the pump to the selector when a hydraulic pressure signal is supplied. A switching valve is movable between a supply position in which the hydraulic pressure is supplied to the pressure regulating valve, and a discharge position in which the hydraulic pressure is discharged from the pressure regulating valve, the switching valve being switched to the supply position when the hydraulic pressure supplied to the high speed engaging device through the electromagnetic valve associated with the high speed engaging device becomes higher than a predetermined value.

摘要： A hydraulic oil pressure changeover mechanism for switching an input pressure to a solenoid valve between a high pressure and a low pressure. The changeover mechanism is made up of: a pressure reduction valve to be switched between an operating condition for outputting a low hydraulic oil pressure and a non-operating condition for outputting a high hydraulic oil pressure; a changeover valve to be switched between a low-pressure position for inputting an output pressure from the pressure reduction valve to the solenoid valve and a high-pressure position for inputting a hydraulic oil pressure to be supplied without passing through the pressure reduction valve to the solenoid valve; and a control valve to be switched between a first position for outputting a first signal pressure to switch the pressure reduction valve to the non-operating condition and a second position for outputting a second signal pressure which operates in a direction to switch the changeover valve to the low-pressure position. The changeover valve can be switched to the low-pressure position when the second signal pressure and a third signal pressure are operated on the changeover valve.

摘要： A changeover valve is provided on an upstream side of solenoid valves for hydraulic engaging elements. The changeover valve is urged to the closed position by the hydraulic oil pressure of a plurality of hydraulic engaging elements which are concerned with the speed changing. At the time of failure in which three or more of the hydraulic engaging elements are simultaneously engaged, the changeover valve is changed over to the closed position to thereby lower the hydraulic oil pressure in the hydraulic engaging elements on the downstream side of the changeover valve, whereby the simultaneous engagement is prevented. In the closed position, a hydraulic oil pressure of a predetermined pressure is inputted to the changeover valve via an oil passage. The chattering of the changeover valve is thus prevented even if the hydraulic oil pressure in the hydraulic engaging elements may be lowered.
摘要翻译：在用于液压接合元件的电磁阀的上游侧设置有切换阀。通过与变速有关的多个液压接合元件的液压油压将转换阀推到关闭位置。在三个以上的液压接合元件同时接合的故障时，转换阀转换到关闭位置，从而降低转换阀下游侧的液压接合元件中的液压油压力，从而防止同时接合。在关闭位置，通过油路将经过预定压力的液压油压输入切换阀。因此即使液压接合元件中的液压油压力可能降低，也可以防止转换阀的振动。

摘要： An automatic transmission on an automobile has an input shaft, an output shaft, a plurality of power transmitting paths disposed between the input and output shafts for establishing respective gear positions, and a plurality of engaging elements for selecting one of the power transmitting paths at a time. A shift controller disengages a previous-position engaging element and engages a next-position engaging element to switch from one of the power transmitting paths to another for thereby effecting a shift from a previous gear position to a next gear position. The shift controller provides a plurality of previous-position stages for controlling the previous-position engaging element with respective different characteristics to vary forces to disengage the previous-position engaging element in each of the gear positions, and a plurality of next-position stages for controlling the next-position engaging element with respective different characteristics to vary forces to engage the next-position engaging element in each of the gear positions. The shift controller executes the previous-position stages and the next-position stages to effect a shift between gear positions according to a change in the rotational speed of the input shaft, and executes all or selected ones of the previous-position stages and the next-position stages successively in order.
