    Abstract: A gear-shifting device for a vehicle is provided and includes a guide body that has a first end portion connected to a control shaft, installed so that a second end portion is rotated at the first end portion as an axis in a rotational displacement that corresponds to a selecting path to perform a selecting operation, and installed to be moved in a substantially straight displacement that corresponds to a shifting path along an axis direction of the first end portion to perform a shifting operation. A guide unit is disposed to distinguish each shifting path on the selecting path in which the second end portion of the guide body is rotated and is configured to guide the second end portion of the guide body to be movable along the shifting path.

  • Patent number: 9490082
    Abstract: Next to a handle element, a bicycle handle system comprises a control element adapted to be fastened on the handlebar and serving to control an electric auxiliary motor. The control element has an actuation element rotatable on a bearing element. By turning the actuation element from a rest position to in particular two different activation positions, the assisting power from the auxiliary motor can be increased or reduced. For a simple, intuitive actuation of the actuation element, a return element is provided by which the actuation element is automatically returned from the first and, if applicable, the second activation position to a rest position.

  • Patent number: 9217491
    Abstract: A reverse arm is pivoted by a driving pin of a reverse fork inserted into a driven hole thereof, and the reverse arm thereby moves an idle gear in an axial direction, whereby the idle gear is engaged with and disengaged from a driving gear and a driven gear of a reverse gear train. The outside diameter of the driving pin is smaller than the width between opposed flat inner side surfaces of the driven hole of the reverse arm; thus, a gap is formed between the driving pin and the inner side surfaces. A jump-over mechanism JO is provided between the reverse arm and a transmission casing for elastically urging the reverse arm outward away from a predetermined intermediate position within the pivoting range of the reverse arm and brings the driving pin in contact with one of the inner side surfaces of the driven hole.

    Abstract: A shift device with an over-shift lock for a multi-speed transmission of a motor vehicle, in which individual gears are shifted incrementally, is provided. The shift device has a pivotable shifting element which is composed of an activation element and a driver element displaceably held thereon. Both elements have mutually aligned oblong holes which are penetrated by a shifting shaft leading to the transmission. A shifting process is limited by the striking of the shifting shaft against the end sides of the oblong holes. In this position, the alternating influencing of the shifting shaft and the contours of the oblong holes prevents a further rotation of the shifting shaft and thereby an over-shifting of the transmission.

    Abstract: A switching mechanism includes a main body, a rotational body, a swinging member, and a biasing member. The swinging member detaches from the shaft portion against a biasing force of the biasing member by a centrifugal force generated at the swinging member in response to rotation of the rotational body rotating in conjunction with movement of the rotational member, for example, a vehicle door, to switch the state of the switching mechanism to an operation allowed state in a state where the rotational member is operated to rotationally move. The biasing force of the biasing member pushes the swinging member to make contact with the shaft portion and engages with the shaft portion by friction to retain the rotational body in a stopped state to switch the state of the switching mechanism to a movement restrained state in a state where the rotational member is stopped from making rotational movement.

  • Publication number: 20120247255
    Abstract: A monorail shifting device (1) for a multi-gear variable-speed transmission with a gearshift rail (2), a shifting element (3) and a selector element (5). The gearshift rail (2) is arranged and can be displaced axially, in a transmission housing (10), and the shifting element (3) is connected to the gearshift rail (2), fixed in the axial direction. The shifting element (3) transmits axial shifting movement selectively to one of a plurality of shifting fork arms (6, 7, 8). Relative to the transmission housing (10), the selector element (5) is fixed in the axial direction on the housing. The shifting element (3) and the selector element (5) can pivot together about a central axis (11). A shift position detent (18) acts between the shifting element (3) and the selector element (5). Furthermore, the monorail shifting device is typically incorporated into a multi-gear variable-speed transmission.

  • Patent number: 8276473
    Abstract: A shift-drum apparatus for a gear-type transmission including a plurality of shift forks and a shift drum provided at its outer peripheral surface with a plurality of shift grooves, in which a state of the gear-type transmission is shifted between a neutral state and a plurality of transmission gear stages. The number of shift forks is the same as the number of the transmission gear stages, and each of the shift grooves includes one or more gear-shifting recesses that are depressed in an axial direction of the shift drum. The shift forks are biased in the axial direction respectively by springs toward the corresponding gear-shifting recesses. Two of the gear-shifting recesses are formed in at least one of the shift grooves, while two of the shift forks are engaged with the shift groove.

  • Patent number: 8267373
    Abstract: A single lever control for manually manipulating a hydraulic valve spool of a directional control valve, which comprises an elongate shaft encased within an outer casing and having first and second ends each being fixedly attached to an end cap and a pivot block, respectively. The outer casing comprising a cylindrical cup for housing a biasing element whereupon an applied upward force on the cylindrical cup causes the outer casing to move upwardly to the extent of lifting a latching member pivotally connected to the pivot block and releasing a locking mechanism. The mounting assembly comprising an adapter plate integrally connected to a vertical support member and having a large aperture for receiving a moveable stem associated with the hydraulic valve spool, an arrangement of which allows a valve-actuating stem associated with the pivot block to movably interact with the moveable stem as the single lever control is selectively manipulated.

    Abstract: A transmission for a vehicle for performing a shift manipulation at a desired time while ensuring a favorable operation feeling. A lost motion member is arranged in a shift drive force transmitting mechanism arranged between a shift spindle and a shift drum, and a rotary position of the shift drum is resiliently held by a shift stopper mechanism in a state where one of a plurality of gear trains is established or in a neutral state. A state which allows a changeover operation of an established state of a plurality of gear trains due to an action of a shift drive force which is temporarily accumulated by a lost motion means and a state which interrupts the changeover operation can be changed over by a shift restricting mechanism which is provided as a part separate from a shift stopper mechanism.
