    摘要: A hydraulic control system comprises a control valve with a solenoid valve operatively connected thereto to modulate the characteristic of hydraulic fluid pressure supplied to a friction element that is to be engaged during a shift in speed ratio. The current supplied to the solenoid is varied in ON/OFF manner in accordance with a duty factor computed by a control unit. The control unit includes a memory storing a map containing various duty factors corresponding to various kinds of shifts and determines an adequate duty factor for a shift which is to take place in the transmission. The characteristic of the hydraulic fluid pressure is modulated during a time period variable with vehicle speed and engine torque which are measured by sensors associated with the control unit.

    摘要: In order to stabilize the line pressure developed by a line pressure regulator valve and simultaneously control the operation of a variable capacity pump in a manner that the latter exhibits the desired degree of response to changes in the line pressure, a flow restriction is defined in the bore of the valve itself. This flow restriction is defined between the wall of the bore in which the spool is disposed and a portion of the spool which extends between two adjacent lands and which has a diameter which is slightly smaller than that of the bore.

    摘要: An automatic transaxle comprises a rotary motion transmitting unit which transmits a rotary motion between two parallel shafts including an input shaft in driving connection with a turbine of a hydrodynamic unit, i.e., a torque converter. The rotary motion transmitting unit includes a driver sprocket, a follower sprocket, and a chain in driving connection between the sprockets. The pump has a pump housing fixed to a stationary support plate. The driver and follower sprockets are rotatably supported at this stationary support plate. A reaction shaft in driving connection with an inner race of a one-way clutch of a stator of the torque converter extends through the stationary support plate and rotatably supports the driver sprocket. The reaction shaft is hollow to allow the input shaft to extend therethrough. The input shaft is drivingly connected with the driver sprocket. The pump has a pump shaft including a sleeve portion coaxially arranged around and with the reaction shaft and a radial extension fixed to the impeller. Accordingly, the driver is spaced further away from the torque converter in a direction along the input shaft than the pump.

    摘要: A shift control system for an automatic transmission is disclosed, which comprises, in the first embodiment for example, an orifice bypass valve including a spool, a spring and a pilot port. The spool is movable between an interrupting position where a first hydraulic passage is interrupted from a third hydraulic passage, and a connecting position where a first passage is connected with a third passage, and it is pressed to the interrupting position by the spring. The pilot port induces a force by which the spool is pressed in the direction opposite to a force of the spring when the hydraulic fluid is supplied, and it is connected with a fourth hydraulic passage for receiving the hydraulic fluid for operating an overrunning clutch.

    摘要: A shift valve which controls the shifting of the transmission between the top speed and the next lower one is arranged to have a port which is communicable with an overrunning clutch viz a relatively short conduit arrangement. The port is arranged to be constantly supplied with line pressure while the manual valve is set in any of the forward drive ranges, and to be communicated with the conduit when the shift valve is supplied with a top speed inhibit signal and induced to assume its downshift position.
