  • Patent number: 9127767
    Abstract: An operating device for an automatically switched manual gearbox. The gearbox has a movable engagement element for each gear. The device has rotary shafts (1) and rotatable shift fingers (2, 3, 4) to move selected engagement elements each for a gear. Each separate shift finger (2, 3, 4) is associated with a specific engagement element. Each shaft finger (2, 3, 4) is separately pivotable independently of the other shift fingers (2, 3, 4). An axially shiftable slide has a connector to each of the fingers at respective axially shifted positions of the slide.

  • Patent number: 8127637
    Abstract: A control device for controlling engagement of desired gears of a gearbox. The control device includes a holder unit and at least one control rod which has a relating locking arrangement and is arranged for linear movement in the holder unit. The control rod is provided with one or more recesses which each define a predetermined setting position of the control rod relative to the holder unit. The locking arrangement includes a locking device which is movable, substantially perpendicularly to the control rod's longitudinal axis, between a first position in which the locking device engages in one of the recesses in the control rod, and a second position in which the locking device does not engage in any of the recesses in the control rod. A wire spring fastened in a holder arrangement is firmly connected to the holder unit. The locking device is mounted on or forms part of the wire spring and is movable from the first position to the second position against the action of the spring force of the wire spring.

  • Patent number: 7963187
    Abstract: The invention relates to a control device for controlling the engagement of desired gears of a gearbox, which control device comprises a control rod with a relating locking arrangement. The locking arrangement comprises a locking element provided with one or more grooves or recesses which each define a predetermined setting position of the control rod. The locking arrangement further comprises a resilient locking means arranged in a recess in the control rod, which locking means has a locking portion which, against the action of a spring force of the locking means, is arranged for movement in said recess in the control rod's radial direction between a protruded position in which the locking portion engages in one of said grooves/recesses in the locking element and thereby counteracts movement of the control rod relative to the locking element, and a retracted position in which the locking portion does not engage in any of said grooves/recesses in the locking element.

  • Patent number: 7926558
    Abstract: A cooler device comprising a cooling portion with at least one tubular element which has an internal flow duct for guiding a first medium between a first and a second tank. A second cooling medium in contact with an outside surface of the tubular element cools the first medium as it is led through the flow duct. A first tank receives the first medium before it is led into the cooling portion. The first tank has an outside surface provided with protruding material portions which produce an enlarged contact surface with the cooling second medium so that the first medium is subjected to a first step of cooling within the first tank.

  • Patent number: 7828044
    Abstract: A charge air cooler comprising at least one tubular element with an internal flow duct for leading compressed air between an inlet aperture and an outlet aperture. A medium at a lower temperature than the compressed air is caused to flow in contact with an outside surface of the tubular element cooling the compressed air in the tubular element when the air is led through the flow duct. A movable control element is arranged close to the inlet aperture or the outlet aperture of the flow duct. A control for the control element provides a variable flow of compressed air through the flow duct as the movable control element is placed in various positions.

  • Publication number: 20090145717
    Abstract: A holder for a sensor body for a position sensor. The holder has a holder housing. A circular cylindrical recess with a bottom in the holder housing. A head is connected to one end of the sensor body and the head is adapted, concentrically and by being to a limited extent tiltable from a normal position, to being accommodated and fastened in the cylindrical recess. A compression spring between the head and the bottom of the recess operable to flexibly to preload the head toward a normal position. To ensure that the sensor body cannot permanently change position in the recess and does not risk being subject to wear against a cooperating sensor body, the head has the shape of a central spherical segment with a diameter corresponding to the diameter of the recess and the compression spring is a flat wire spring.
