    15 20 25 30 To maintain a good shifting feel for the driver of the vehicle, the shift lever should not be too long. The movement from the neutral position to the engaged gear shall be in the order of 60-80 mm and the distance laterally between different gear positions in the order of 30-40 mm.
    Due to the requirement to achieve a good shifting feel, it is therefore necessary, especially for larger vehicles, to place the center of rotation of the shift lever above the mounting surface in the cab floor. Such a placement would mean that the attachment of the wires to the gear lever would need to be upp raised from the cab floor, ie. vajrama would have to go into the cab, which should be avoided for production reasons, among other things.
    In order to be able to surface the rotation point of the lever and to avoid having to mount the wire frames inside the cab, a shifting system according to the present invention has been provided.
    The gear lever system according to the present invention allows the movement from the lever to be transmitted to the wire frames in the desired manner, and ensures, among other things, that raw pull and pressure direction is applied to the wires.
    The advantage of the solution is that a shorter gear lever can be used, despite the fact that the wire frames are mounted under the cab floor and do not need to be led into the cab.
    The gear lever system also allows the design to be adapted to the pull and pressure directions of the wires, for example if the gear servo should require it.
    A solution for the gear lever mechanism is constructed with a linkage system that has been adapted to the requirements of the prevailing equipment. The linkage system thus allows the movement from the lever to be transmitted to the wire frames in the desired manner. The solution also ensures that the correct pull and pressure direction in the wire frame is achieved.
    By constructing the transmission links according to the present invention, the volume of the shift mechanism can be kept as small as possible. It also allows the wire frames to be mounted under the cab floor. Brief Description of the Drawings Figure 1 shows a perspective view of a gear lever system according to the present invention.

    Detailed Description of Preferred Embodiments of the Invention The present invention will now be described in detail with reference to the figures. In the figures, the same reference numerals have been used throughout to denote the same or an equivalent detail.
    The invention thus relates to a gear lever system (see in particular Figures 1, 4 and 5) for wire shifting of a vehicle, preferably a truck, adapted to transmit gear movements from the gear lever 2 to two gear wires 4, 6, the gear wires running substantially horizontally from a position below the vehicle's cab and into the vehicle's gearbox. In the figures, the shift wires are arranged to run in protective bellows.
    The gear lever system comprises a gear lever 2, a spherical bearing 8 with a pivot point C around which said gear lever is movable, a first transfer link 10 and a second transfer link 12 adapted to be actuated depending on gear movements applied to the gear lever 2. The first and second transfer links 10, 12 are arranged in connection with the lower end of the gear lever. The gear lever system according to the invention allows the gear lever to be movable to the right and left, seen from the driver, along a first gear movement A which is indicated by a bidirectional arrow A in the figures.
    The shifting motion A refers to movement in the neutral position of the gearbox and can also be indicated as perpendicular to the longitudinal direction of the vehicle.
    The shifting movement B refers to movement from the neutral position of the gearbox to the desired shifting position and takes place in parallel with the longitudinal direction of the vehicle.
    Figure 2 shows an example of a shift pattern where R denotes reverse gear, C creeps gear and 1, 2 and 3 forward gears.
    According to the invention, the first transmission link 10 is adapted to directly transmit a shifting movement A, which is thus substantially perpendicular to the longitudinal direction of the vehicle, to the first shifting wire 4, and that the second transmission link 12 is adapted to transmit a shifting movement via rotation of a vertical shaft 14. B, which is substantially parallel to the longitudinal direction of the vehicle, to the second shift road 6.
    The first transfer link 10 is fixed in a bearing 16 such that the first transfer link 10 is movable about a horizontal side impact axis 18, and that the longitudinal axis A1 of the side impact axis is a predetermined distance from the point of rotation C of the spherical bearing 8. The first transfer link 10 is adapted to be actuated of the gear lever via a transfer shaft 20 having a longitudinal axis A2 passing through the point of rotation C of the spherical bearing. One end of the transfer shaft is attached to the lower part of the gear lever and thus moves plain bearing 22. The plain bearing 22 allows the transmission shaft from the gear lever to be angled, rotated, and slid substantially perpendicular to the first transmission link. The first transfer link 10 further comprises a lower part 24 with an attachment point 26 with a bearing 28 for the first shift wire 4, where the attachment point is located a predetermined vertical distance h below the bearing 16 for the side impact shaft 18.
    Figure 3 shows a schematic view of the first transmission link according to an embodiment of the present invention.
    In the embodiment illustrated in Figures 1, 4 and 5 and also schematically shown in Figure 3, the first transmission link 10 is adapted to rotate about the side impact shaft 18 via the bearing 16 by actuating the gear lever via the transmission shaft 20 via the plain bearing 22 where the bearing 22 is located in front , seen in the longitudinal direction of the vehicle, the bearing 16. Thereby a movement of the gear wire 4 is effected which means that when the gear lever with the gear movement A is moved to the right the gear wire 4 will be inserted into the gearbox and when the gear lever is moved to the left the gear wire 4 will be pulled out of the gearbox.
    According to another embodiment, opposite movements of the shift wire can be obtained if instead the bearing 16 around which the transmission link rotates is instead placed in the position where the sliding bearing 22 is placed according to the embodiment described above and the sliding bearing 22 is placed at the location of the bearing 16.
    The second transfer link 12 comprises a substantially horizontally oriented strut 30 which at its one end 32 is hingedly attached to the lower part of the gear lever and at its second end 34 is hingedly connected to a first end 36 of a first elongate linker 38 40 is fixedly mounted to the upper part of said vertical shaft 14.
    The first link jug 38 is oriented so that its greatest extent is in a direction which is substantially perpendicular to the shifting movement B.
    The bearing connecting the strut 30 to the first linker 38 is a spherical bearing 42 which allows the horizontal strut 30 to be subjected to some rotation along its longitudinal axis A4 (see Figure 7) relative to the point of rotation of the bearing.
    The vertical shaft 14 is in its lower part fixedly connected to a second elongate link arm 44 which in turn is attached to the second horizontally arranged gear wire 6, and that the second link arm 44 has an orientation which substantially corresponds to the orientation of the first linker 38.
    The vertical axis 14 has a predetermined length 1 which is of the same order of magnitude as the predetermined distance h of the first transmission link 10.
    The gear lever system further comprises a mounting plate 5 on which the gear lever and the transfer links are mounted. The mounting plate is adapted to be attached to the floor of the vehicle's cab, for example via screw connections. The plate is provided, among other things, with an elongate opening 7 adapted so that the lower part of the first transmission link can pass through the mounting plate for co-operation with the first shift wire.
    The mounting plate further comprises a vertical hole adapted for the vertical bar.
    A shifting maneuver consists of two phases, first the first shifting movement A is performed, ie. the movement of the gear lever to the desired position along the line A. This movement causes a rotational movement about the point of rotation C, and about the longitudinal axis A3 shown in Fig. 6, and causes the first transmission link to be forced, by actuating the transmission shaft, to rotate about the axis A1 in such a way that, according to the embodiment shown in the figures, a movement to the right of the gear lever causes the front part of the transmission link to move upwards and this causes the lower part of the transmission link to actuate the first shift wire in a direction into the gearbox.
    A movement to the left of the gear lever causes the first transmission link, by actuating the transmission shaft, to rotate about the axis A1 in such a way that it causes the front part of the transmission link to move downwards and this causes the lower part of the first transmission link to act on the first shift wire em in one direction out of the gearbox.
    The second transfer link 12 will be substantially stationary when the gear lever is moved in the neutral position, i.e. according to shifting movement A. 10 15 20 25 30 The second phase of the shifting maneuver means that the driver moves the shift lever to the desired shifting position upwards or downwards from the neutral position, ie. shifting movement B. This movement also takes place through a rotational movement around the point of rotation C where the sliding bearing contributes to the first transmission link remaining in its position.
    The second transmission link 12 is thus adapted to transmit longitudinal movements of the gear lever. The second transmission link thus comprises a substantially horizontally oriented strut 30 which at its one end is hingedly attached to the lower part of the gear lever.
    The horizontally oriented strut is preferably hinged to the lower part of the gear lever via a bearing so that it is movable in a vertical plane. At its other end, the horizontally oriented strut is articulated connected to a first part of a first elongate link arm 38 which in its opposite second part is fixedly mounted to the upper part of a vertical shaft 14.
    The bearing connecting the strut to the first linker is preferably a spherical bearing 42 which allows the horizontal strut to be subjected to some rotation along its longitudinal axis A4 relative to the point of rotation of the bearing.
    The second part of the first link rail is thus fixedly mounted to the vertical shaft, for example via a screw connection.
    The first linker is oriented so that its largest extent is in a direction which is substantially perpendicular to the shifting movement B.
    Thanks to the spherical bearing, the first link bar will be substantially still when the gear lever is moved in the neutral position, ie. in the shifting movement A.
    The vertical shaft is in its lower part fixedly connected to a second elongate link arm 44 which in turn is attached to the second horizontally arranged gear cable 6.
    The second link frame has an orientation that substantially corresponds to the first link frame.
    Longitudinal movements of the shift lever (shift movement B) are thus transmitted via the horizontally oriented strut to the first link arm which in turn affects the vertical axis which is rotated along the vertical axis. The movement of the vertical axis affects the second linker which transmits the movement to the second gear. The vertical axis has a length 1 which is of the same order of magnitude as the height h of the first transmission link.
    In the embodiment shown in the figures, a rearward movement of the gear lever, e.g. when loading gear 3 (see figure 2) the first link is moved backwards which causes the vertical shaft to be rotated and the movement is transmitted to the second link which acts on the second gear in a direction out of the gearbox. Correspondingly, a forward movement of the gear lever, e.g. when loading gear 2 (see Figure 2), the second link lever acts on the second gear wire in one direction into the gearbox. In this embodiment, the first and second linkers have the same orientation. If they are instead directed in opposite directions, reverse directions for how the gear is affected can be achieved.
    Typical stroke lengths of the shift wires are +/- 25 mm. Other stroke lengths are of course possible to achieve by changing, for example, raising the height of the first transmission link, or by changing the length of the first or second link arm.
    The present invention is not limited to the above-described preferred embodiments.
    Various alternatives, modifications and equivalents can be used. The above embodiments are therefore not to be construed as limiting the scope of the invention as defined by the appended claims.
