  • Patent number: 7955204
    Abstract: In a stepping motor cooling apparatus for a belt-type continuously variable transmission, a pair of primary and secondary pulleys are disposed inside a transmission case, and a forward/backward switching unit is disposed coaxially to the primary pulley, furthermore, a stepping motor is disposed below the forward/backward switching unit. An inner case originating from the transmission case surrounds a circumference of the forward/backward switching unit. Through the inner case, a dripping hole is formed at an inner case's portion directly above the stepping motor so that working fluid drained from the forward/backward switching unit can drip on the stepping motor. In order to further improve the cooling effect of the stepping motor, a recess portion is formed immediately below the stepping motor at an upper surface of a valve body disposed under the stepping motor.

  • Patent number: 7244202
    Abstract: A step motor positioning structure for a belt-type continuously variable transmission having a speed-change control valve for controlling a primary pressure to be supplied to a primary pulley, a servo link, and a step motor for driving, by way of the servo link, the speed-change control valve in response to a speed-change command signal is provided. The step motor positioning structure includes a motor bracket formed integral with the step motor and having an elongated hole and a circular hole, a bracket support supporting thereon the motor bracket, a first positioning member protruding outward from the bracket support and inserted in the elongated hole, and a second positioning member protruding outward from the motor support and inserted in the circular hole.

  • Patent number: 6811423
    Abstract: A first mark (28) is provided on a rotatable member (4), or on a connector (3) on which the rotatable member (4) is rotatably mounted. A second mark (30) is provided on the connector (3) on which the rotatable member (4) is rotatably mounted, or on the rotatable member (4) so as to be ascertained whether or not a pair of connectors (2), (3) are fully engaged with each other. Thus, a full engagement condition is ascertained without additional parts. Preferably, the first mark (28) or the second mark (30) is a projecting part (28) provided on the engaging arm (27) which is mounted resiliently on the rotatable member (4) or on the connector (3) on which the rotatable member (4) is rotatably mounted. Also preferably, the second mark (30) or the first mark (28) is the engaging part (30) with which the projecting part (28) is engaged.

  • Patent number: 5949041
    Abstract: An automatic-transmission control for outputting a switch signal of a shift position is produced as follows. A first terminal unit includes small-power fixed contacts coupled with small-power contacts of a connector through a coupling portion, is formed. A second terminal unit, which includes large-power fixed contacts coupled with large-power contacts of a connector through a coupling portion, is formed. A positioning resin block is formed to at least one of the first and second terminal units. The first and second terminal units are laminated through the positioning block. A switch body and a connector are molded upon inserting the laminated first and second terminal units in a molding die. The switch body and the connector are separated by cutting the coupling portion.
