  • Patent number: 8068957
    Abstract: A vehicular backing operation assist apparatus is coupled with a movement direction demand unit for demanding a forward or backward movement of the vehicle and a change detection unit for detecting a change of a state of the vehicle taking place in association with a start-up of the vehicle. A reverse departure, which is a backing operation for exiting a parking state, is determined to be performed if a transit period from when the change of the state is detected to when the backward movement is demanded, is within a predetermined period. A reverse parking, which is a backing operation for entering a parking state, is performed, if the transit period is greater than or equal to the predetermined period. An assist control unit then provides an assist item for a backing operation relative to either the reverse departure or the reverse parking, which is determined to be performed.

  • Patent number: 8001777
    Abstract: An axle driving apparatus in which a hydraulic pump and a hydraulic motor which constitute a hydrostatic transmission are disposed on a center section. In a horizontal portion of the center section are provided a pair of linear oil passages in parallel to each other. A pair of arcuate ports are provided on a pump mounting surface formed on the horizontal portion of the center section. The pair of arcuate ports are substantially perpendicular with respect to the direction in which the oil passages extend. The axis of slanting movement of a movable swash plate of the hydraulic pump extends laterally of the vehicle body on which the axle driving apparatus is provided. The rotating direction of an arm provided on a control shaft for slantingly operating the movable swash plate is coincident with the operating direction of a control rod connected with a speed changing member. Thus, the link mechanism for connecting the speed changing member and the control arm for the movable swash plate is simplified.

  • Publication number: 20110168933
    Abstract: An adjusting screw structure of an oil immersed solenoid comprises a movable core provided in a first space of a main body case to be movable in an axial direction. The core is biased by an adjusting spring to be pulled by a fixed magnetic pole portion. An adjusting screw capable of adjusting biasing force of the adjusting spring is included. The adjusting screw structure includes an air-bleeding plug configured to detachably attach to and seal an opening end portion of a rear case, which communicates with the first space. The air-bleeding plug includes an internal screw portion that threadedly engages the adjustable screw. A detachable mechanism is configured to attach the air-bleeding plug to the opening end portion, locating the air-bleeding plug at a predetermined attachment position in a movement direction of the adjusting screw. Thus, air in a solenoid can be removed without causing a biasing force error.
