Definitions

• the present invention relates to a manoeuvering arrangement according to the preamble of appended claim 1.
• a manoeuvering arrangement is a gear-change control for automatic gearboxes in motor vehicles.
• Known gear-change controls are provided with e.g. a three- di ensionally-formed bracket in injection-moulded plastic, which gives rise to high tooling costs.
• An alternative known solution is to form the bracket in form-pressed plate, which leads to a large amount of welding and assembly work, as well as high tooling costs.
• the object of the present invention is to arrive at a manoeuvering arrangement which can be produced at relatively low cost, with precise tolerances and a high degree of flexibility in the construction, as well as requiring low investment.
• Fig.l shows a perspective view of a manoeuvering arrangement according to the invention in the form of a gear-change control
• Fig.2 shows a side view of the gear-change control in an assembled condition
• Fig.3 shows a fixed bracket portion, intended for an alternative fixed attachment in a vehicle
• Fig.4 shows a partially sectioned end view of the gear-change control according to the invention.
• the manoeuvering arrangement is shown in the drawings as an example in the form of a gear-change control for an automatic gearbox in a motor vehicle and presents two main portions, namely a manoeuvering lever 1 and a manoeuvering bracket 2 (see for example Fig.l and Fig.2).
• the manoeuvering lever 1 is pivotally attached to the manoeuvering bracket 2 via a pivot joint 3, whereby the pivot axis of the manoeuvering lever has a defined position relative to the manoeuvering bracket.
• the transmission in the shown example, has been given the form of a wire 6, the casing 7 of which is fastened by means of a fastening 8 to the manoeuvering bracket 2.
• the transmission is given the form of a linkage system where, instead, a link arm is fastened in a corresponding fastening point 5 in the lever 2. In this way, no fastening for the casing is required.
• the manoeuvering bracket 2 is advantageously produced from an extruded section of metal for instance, such as aluminium or an alloy thereof. By extruding (extrusion- moulding), the section can be provided with a plurality of functions at relatively low cost by suitable choice of the shape of the section.
• the manoeuvering bracket 2 is produced by cutting the continually-produced section in straight-cut sections so that two planar, substantially parallel sides are obtained.
• the manoeuvering bracket 2 presents a base portion 10 which carries the pivot joint 3 for the manoeuvering lever 1.
• the pivot joint 3, in the shown example, is basically formed as a continuous hole or a recess in the base portion 10 of the manoeuvering bracket 2, in order to accommodate a pivot shaft 11, which is constituted for example by a screw which extends through the lower end 12 of the manoeuvering lever 1.
• the manoeuvering lever is formed with two flanges 13, 14 which extend on respective sides of the two sides 15, 16 of the manoeuvering bracket, and are formed with holes for pivot shaft 11 or the screw, whereby the screw head 17 and nut 18 contact the outer sides of the two flanges. With the aid of distance shims, the inner sides 19, 20 of the flanges are normally kept at a distance from the manoeuvering bracket, the two sides 15, 16 of which form stop surfaces against strong sideways movements of the lever 1.
• the manoeuvering bracket 2 presents an arm 21 projecting up from the base portion 10, said arm supporting the attachment for the wire casing 7.
• the manoeuvering bracket is further formed with a substantially circular-arc formed portion in the form of an arm 22 projecting up from the base portion 10.
• the arm 22, in the shown example, is provided with means 23 for positional indexing in the form of preferably rounded grooves on one side of the arm, in this case the upper side, which set the lever in determined pivotal positions around the pivot joint 3 and thereby determine the gear positions of the gear-change control.
• a groove is thus arranged for each gear position and cooperates with an indexing element 24, which suitably has a rounded end surface 25 cooperating with the rounded grooves 23.
• the indexing element is biased by a compression spring 26, by means of which the indexing element is urged to adopt a particular position in respective grooves and thereby determines the position of the gear-change lever.
• the manoeuvering arrangement according to the invention is of the type in which the manoeuvering lever 1 is intended to be displaced between certain of the gear positions by means of both a pivoting movement around the pivot joint 3 as well as a sideways movement in order to make it possible to guide the lever between certain of the gear positions.
• the movement path of the gear lever 1 is determined by a guide unit 30 which is substantially fixedly arranged in the installation set-up of the manoeuvering arrangement, in the present case being fixedly arranged relative to the vehicle ' s fixed decor.
• the guide arrangement 30 consists of a plate 31, which in the shown example has the form of part of a cylindrical casing and presents a guide track 32, through which the gear lever extends .
• the guide track suitably has a breadth which is somewhat greater than the lateral dimension of the gear lever and extends in a zig ⁇ zag shape with longitudinal track portions 33, 34, 35 which extend substantially in the direction of movement which the lever undergoes in its pivotal movement around the pivot joint 3.
• These longitudinal track portions 33, 34, 35 are displaced in a parallel manner with respect to each other, but connected so that a combined track is formed, but so that each track portion presents laterally located abutment edges 36, 37, 38, 39, at its ends, which limit the range of movement of the gear lever in as far as concerns its pivotal movement around the pivot joint 3 with when the shaft direction remains unchanged.
• manoeuvering bracket 2 the manoeuvering lever 1 and the parts supported by these, namely form a combined unit which is pivotally attached relative to the base on which the manoeuvering bracket is mounted.
• the manoeuvering bracket and the manoeuvering lever 1 can be pivoted around a pivot axis 40 which extends transversely, preferably perpendicularly to the geometrical pivot axis 11 of the pivot joint 3 so that the gear lever, during its pivotal movement about the pivotal joint 3, can be displaced into different movement planes coinciding with the second pivot axis 40.
• the second pivot axis 40 extends substantially in the longitudinal direction of the vehicle, whilst the first pivot axis 11 extends substantially in its transverse direction within an angular range determined by the guide track 32.
• the pivotal movement of the manoeuvering arrangement around the second pivot axis 40 is ensured by means of the manoeuvering bracket 2 presenting two downwardly-projecting fastening flanges 41, 42 with fastening holes 43, 44 which are respectively co-axial and which define the position of the pivot axis 40.
• the two fastening flanges 41, 42 each form a pivot joint together with a shaft introduced through the holes 43, 44, said shaft being constituted by a screw 45 in the assembled embodiment shown in fig. 2, which is fixed to plates 46, 47 of the vehicle bodywork, preferably screwed into a fixedly- mounted nut 48 attached to the plate.
• a common longitudinal shaft may extend through both holes, it being mounted to the bodywork at its ends .
• Fig. 3 shows an alternative to the assembly shown in fig. 2.
• a fixed attachment bracket 49 with a fastening plate 50 is provided, said fastening plate being intended to be fixed to a planar portion of the bodywork by means of screws 51, 52.
• the fixed bracket additionally presents two fastening flanges 54, 55 with two co-axial holes 56, 57 intended for the insertion of the physical shaft of the pivot axis 40, in the shown example this being constituted by the two screws 45, the head 58 of which and the screwed-on nut of which form axial abutments .
• Fig. 4 shows the guide arrangements 30 in cross-section, from which it can be seen that a suitable spring, for example a compression spring 59, is arranged to maintain the manoeuvering lever so that it is urged to follow one edge of the longitudinal track portions 33, 34, 35, in order thereby to avoid play and resultant dissonant noise.
• a suitable spring for example a compression spring 59
• the arm 22 can in principal be omitted and the indexing completely left out or arranged in the guide track 32 of the guide arrangement 30.
• the fastening flanges 42, 43 are arranged at respective ends of the manoeuvering bracket 2, but they can be arranged at the same end or be replaced by a fastening flange 43 which is thick enough so that a stable pivot function can be obtained with only one flange. It is clear that the screws which are used for the pivotal function are fastened with an amount of play so that a pivotal movement with well- balanced level of friction is obtained.
• the whole extent of the guide track 32 is not disclosed in the drawings, but it can be arranged in many different ways according to the particular gear positions and blocking functions. If additional blocking possibilities are required, an additional per se known blocking mechanism can be arranged for producing blocking between the manoeuvering lever 1 and the manoeuvering bracket 2.
• This blocking mechanism preferably has a movable blocking element associated with the manoeuvering lever, which is movable relative to this between blocking and release positions, said blocking element being manoeuvered from the knob 60 of the manoeuvering lever.
• This blocking element cooperates with recesses in the arm 22 of the manoeuvering bracket 2, which arm is hereby formed with two lateral stop-surfaces, against which surfaces blocking elements will come into blocking abutment when in the blocking position.
