    1015202530to return the trigger to its initial position. It is understood thatthe hook-up rod is carried by the heart disc in a reciprocating motionwhen the heart disc rotates. Furthermore, the heel of the hook bar is formed with aoblique leading edge which slides over the shoulder in the hooking movement and causesa oscillation of the hook bar when the heel passes the shoulder.
    To ensure that the hook of the hook bar is brought into engagement withthe approach for hooking the coupling, the hooking rod is loaded in the directionagainst the approach. In some embodiments, this load is provided by an onthe hook rod pushing piston, which is stored in a housing and driven for exampleof a coil spring which presses the piston against the hooking rod. A disadvantage withthis construction is that penetrating particles, moisture and corrosion can deterioratethe function of the piston and prevent its movement. This disadvantage can lead tohooking up of the coupling is absent.
    To avoid this problem, the invention aims to provide a constructivesimple and reliable hooking of the mechanical coupling in its inactive, noconnected mode.
    BRIEF DESCRIPTION OF THE INVENTIONTo meet this object, a mechanical coupling of according to the invention is providedinitially indicated stroke, in which a leaf spring arranged in the coupling head in abutmentagainst the hooking rod forces the same to under bias from the springpressed against the shoulder in both hooked and disengaged positions.
    Because moving parts are completely missing in the indicated solution, a reliable one is achievedfunction, and in addition a simplified assembly, reduced weight and bettertotal economy.
    The leaf capercaillie can be designed in your own way, and can, for example, have the shape of aelongate element extending from an end attached inside the coupling headarcuate to abut against the hook rod.101520253035The leaf spring can alternatively be designed as an endless element which is clampedarranged between the hook-up rod and an oppositely located attachment point insidethe coupling head.
    The leaf spring can also alternatively be realized as a spiral-shaped element, one of whichend is attached inside the coupling head and whose other and free end abuts againstthe hook bar.
    To avoid the free end of the leaf spring getting caught in the hook bar whenthis moves between disengaged and hooked position, the free end of the leaf spring can beshaped with a radius.
    To reduce the friction between the blades and the hook rod canthe free end of the leaf spring be formed with a radius which abuts in sliding contactagainst the hook bar. For the same reason, the bearing surface of the leaf spring can supporta wear protection in the form of a coating or a sliding heel.
    To distribute the wear over a larger area on the hook bar, it can beadvantageously to arrange said radius in a plane which intersects that of the hooking rodlengthXel at oblique angle, whereby the contact between hook rod andleaf spring has the shape of an oblique over the width of the hook bar continuouslycontact line.
    The attached end of the leaf spring may be attached to the shoulder thereby achieveda compact and space-saving construction. For the same reason, the approach canadvantageously be formed on a bracket supported on a housing serving for storage ofa release device shaped like a spring-loaded rod.
    In a space-saving embodiment, the leaf spring is helically formed in onethe hooking rod cutting plane, and the hooking rod extending throughthe leaf spring coil.
    BRIEF DESCRIPTION OF THE DRAWINGSThe invention is explained in more detail below with reference to the accompanying, schematicdrawings, vari101520253035Fig. 1 shows a coupling head broken away from a traction device in a simplified mannercross section from above;Fig. 2 shows a hooking mechanism mounted in the coupling head in a broken away viewfrom below, on a larger scale and in hooked position;Fig. 3 is a corresponding view showing the hooking mechanism in the disengaged position;Figure 4 is a plan view of a leaf spring included in the hooking mechanism in onefirst embodiment, andFigs. 5A-5B show alternative embodiments of the one included in the hooking mechanismleaf fi vein.
    DETAILED DESCRIPTION OF THE INVENTIONFigure 1 shows a coupling head 1, which has a front plate 2 with a projectionguide cone 3 and an opening 4 intended for receiving an oncoming coupling headguide cone (not shown) when coupling the traction devices. The coupling head houses amechanical coupling comprising a heart disc 5, which is rotatably mounted on an icoupling head mounted main shaft 6. A coupling link 7 is articulated mounted inthe heart disc, which in its periphery has a recess 8 for hooking onecorresponding coupling link of an oncoming traction device. A tension spring 9 loadsthe heart disc in the direction of the coupled position shown in Figure 1. The reference number10 denotes a release device 10 as of the guiding cone of the oncoming coupling headaffected to release a hook-up mechanism described in more detail below withreference to Figures 2 and 3. For the sake of completeness, it should be mentioned that inthe coupling head is typically provided with a driven piston operative to rotate the heart diskin the opposite direction when unloading.
    Figure 2 shows the hooking mechanism in a broken away portion of the coupling headaccording to Figure 1. The hooking mechanism comprises a shoulder 11, ahook rod 12 and a leaf spring 13. The shoulder 11 is arranged inthe coupling head, and is in the embodiment formed on a bracket 14 which issupported on a housing 15 for storing the release device 10. The shoulder 11 can101520253035alternatively be arranged in another suitable way in the coupling head 1.
    The hook-up rod 12 is articulated in the heart disc and is carried thereinrotation around the main axis 6. The hook bar has a lug 16 as withits rear side 17 is hooked against the shoulder 11 in the hooked position shown in figure 2.
    When disengaged, the release device pushes the hook bar offthe shoulder with which the heart disc becomes free to turn to complete connection with itfacing the traction device in the position shown in Figure 3. The front of the lug 18 isinclined to be able to slide over the shoulder when hooking up the mechanicalthe clutch.
    The leaf spring 13 is at one end firmly anchored in the coupling head, and inmore specifically, the embodiment attached to the bracket 14 that providesthe shoulder 11. The free end 19 of the leaf spring abuts against the hook rod 12 andpush it in the direction of the bracket and towards the shoulder 1 1. The free end of the leaf spring19 is suitably bent to a radius r in a plane intersecting that of the hook barlengthXel at an angle. More specifically, the leaf spring 13 of the embodiment issubstantially helical in a plane intersecting the hook bar, andthe hook rod runs through the leaf spring coil.
    The shape of the leaf spring 13 is shown in more detail in Figure 4, in which the drawing plane intersectsthe hook bar at an oblique angle (see section marked cutting throughthe hook bar). Extends from the end mounted at the bracket 14the leaf spring 13 with an arcuate section 20 below and in frontthe hook-up rod 12, seen in the direction from the front plate of the coupling head. Thethe arcuate section merges into a substantially flat section 21 running upwardsbehind the hook bar. The flat section turns into an arcuate section 22which abuts the radius of the hook bar with a radius. Leaf spring 13abuts against the hook-up bar in a contact line that runs obliquely acrossthe back of the hook bar, in 4 gur 4 perpendicular to the drawing figure andrepresented by point C.
    POSSIBLE MODIFICATIONS AND ALTERNATIVE EMBODIMENTSIt will be appreciated that the leaf spring 13 may have a shape other than that shown in Figures 1-4which is only an example which is advantageous because of its simplicity andspace-saving design. Thus, the leaf spring may alternatively, as in FIG10152025305A be designed as an elongate element 13 'which from one inside the coupling headattached end 23 extends in a cup-shaped manner to abut against the hooking rod 12.
    The leaf spring can also, as shown in Figure 5B, alternatively be designed as an endless oneelement 13 ”which is sandwiched between the hooking rod 12 and aoppositely located attachment point 24 inside the coupling head.
    In all cases, the leaf vein can be arranged to extend without the cutting edgeslope relative to the hook rod present in the displaythe working example. Thus, the leaf vein may alternatively be oriented to stretchitself substantially parallel to the hook rod, or have its mainstretching at right angles to the hook bar, if this is preferred, for example, byspace or mounting reasons.
    It is also understood that the attachment of the leaf spring to the coupling head can be performed on something elseway than in the embodiment shown. More specifically, the leaf spring can if sosuitably be attached to the inside of the coupling head housing, or be attached in a oninside shaped bracket.
    Furthermore, the leaf spring can, if applicable, have a wear protection in the form of acoating, or in the form of a sliding heel supported on the leaf fi veinfriction-reducing and durable material.
    It is further understood that the approach 1 1 can cooperate with the hook rodbe arranged in another way in the coupling head. In particular, an alternative is foreseen in whichthe shoulder is formed in a recess in which the heel of the hook rod engages ithooked the mode. In another alternative, the shoulder may be formed on a springboardto engage in the hooked position with a countersunk heel formed throughremoval of material from the hook bar. The invention should therefore notis considered to be limited to the specific design explained in drawings anddescription, but to the solution set out in the appended claims.
