Abstract

1,233,831. Change-speed control. HONDA GIKEN KOGYO K.K. 7 Feb., 1969 [8 Feb., 1968], No. 6883/69. Heading F2D. In an automatic change-speed gear, as described in Specification 1,192,530, providing three forward speeds and reverse (Fig. 1, not shown), movement of a manually operated range-shift valve 30 to control an hydraulicservo 26 operated gear-change member 10, axially moved to establish the first or reverse drives (8) or (9) to the output shaft (7), automatically causes positioning of a valve 31 to connect the servo 27 of an hydraulically operated main clutch 4 to exhaust during that movement, and to a source of pressure for clutch reengagement near the end of completion of the change. In neutral position " N " of the manual valve 30 (Fig. 2, not shown), the gearchange servo 26 and clutch servo 27 are connected via ducts 28 and 29 to exhaust rendering the gear-change member 10 and main clutch 4 inoperative. Rightwards movement of the valve 30 for first gear " D " (Fig. 4) maintains the duct 28 to exhaust and pressurizes the duct 29 to the servo chamber 26a moving the gearchange member 10 leftwards to establish the first gear drive (8), the valve 31, formed on the servo-piston rod 24, re-opening a duct 38 to repressurize the clutch 4 for re-engagement near completion of movement of the gear-change servo-piston 28, whilst leftwards movement of the valve 30 for reverse " R " exhausts the duct 29, and hence exhausts the servo chamber 26a and clutch servo 27 via duct 38, and pressurizes the duct 28 to the servo chamber 26b moving the member 10 rightwards to establish the reverse drive (9), the valve 31 re-opening the duct 38 via a duct 37 to duct 28 to again repressurize and engage the clutch 4 near completion of the change.
