Abstract
Description
- The present invention relates to a front structure of a railway electric locomotive with a retractable door for the access to the automatic coupler.
- The automatic coupling device located in the front side of modern railway locomotives must be housed inside the front structure on account of aerodynamic and aesthetic reasons. However, such coupling must be easily and rapidly accessible to allow the various manoeuvres of the locomotive to be performed. All the known systems provide the presence of a front door with single or double mobile panels which is opened when the access to the automatic coupler is required. In such an occasion, the door or its mobile panels keep on being opened and protruding, even during running. In some cases, in consequence of the shape of the front side of the locomotive, it is impossible to make doors which also allow both the lodging of and the access to the buffers, and alternative technical solutions to carry out the same function must be designed. Furthermore, the presence of front doors very often breaks off the aesthetic continuity of the front structure of the locomotive and causes undesired limitations to its configuration.
- It is an object of the present invention to provide a front structure of a railway locomotive suitable to accomodate the automatic coupler so that it is not normally in view and to make it accessible by means of a a simple manoeuvre, when necessary.
- A particular object of the present invention is to provide a new front structure of a locomotive of the type described above comprising a door suitable to be kept in a opened and a closed position, and equipped with a displacement device for guiding its movement from one position to the other using the manual action of an operator.
- Another object of the present invention is to provide a front structure of a locomotive of the type described above in which the opening and the closing manouvres of the door can be carried out without requiring excessive manual effort and without involving dangerous situations for the operator.
- A further object of the present invention is to provide a front structure of a locomotive of the type described above in which the displacement device is suitable to withstand mechanical and aerodynamic loads caused by train motion both with closed door as well as open door.
- These results are achieved with the front structure for locomotives according to the present invention whose characteristic consists in that it comprises a movable door pivotally connected to said structure and translatable within said structure so that it can be arranged in a closed position and in a open position angularly spaced of about 90° with respect to said closed position and retracted inside said structure.
- In the preferred embodiment of the invention a door displacement unit is provided for transmitting to the door a substantially translational motion inside the structure along the longitudinal axis of the locomotive, whereas the rotatory motion of the door is manually performed by the operator against the resistance of elastic means which tend to keep the door in the closed position.
- In particular, the door is hingedly suspended from the fixed part of the structure and is slidingly mounted, along the edges of the front opening, to achieve its axial translational motion.
- Further characteristics and advantages of the front structure of the locomotive according to the present invention will become more apparent in the following description of one of its possible embodiments, given as an example and not limitative, with reference to the attached drawings in which:
- figures 1, 2 and 3 are schematic side views of the front structure of a locomotive according to the invention in which the movable door is respectively in a closed position, an internally translated position, and an opened position;
- figure 4 is a plan view of a side of the front structure of the locomotive according to the present invention;
- figure 5 is a sectional side view according to arrows V-V of figure 6;
- figures 6 and 7 show in partially sectional front views of the right and the left side respectively of the front structure of the locomotive according to the present invention.
- With reference to figure 1, there has been indicated at 1 an outline of the fixed front part of a railway locomotive on which an opening 1a is formed, and at 2 a movable front part, thereof hereinafter called "nose". The movable front part or
nose 2 has such a shape that it can be accomodated without discontinuity within opening 1a and is pivotally connected at 3, to a floatingframe 4 hinged at 5 to ananchor plate 6 integral with fixedfront part 1 of the locomotive. Anarm 7, integral withnose 2, is connected toplate 6 byelastic means 8 urging againstarm 7. - Sideways floating frame 4 a nose displacement unit is provided, generally indicated at 9, fixed to the body of
buffers 10, which are mounted on the end sill (not shown) of the locomotive. Thedisplacement unit 9 is connected to thefloating frame 4 by connecting rod means 11. - As described in more detail in figures 4 and 5, floating
frame 4 has light metal box-shaped construction and comprises an extrudedtubular cross bar 12 with square section and side-arms cross bar 12. The upper side-arms 13, which lean forward with respect to the alignment axis with the lower side-arms 14, are connected by means ofpivots 5 to therespective plates 6, which are fitted in the composite material of the front of the locomotive, whereas the lower side-arms 14 are connected toplates 15 which are fixed to the sides ofnose 2 by means ofpivots 3. Fromplates 15arms 7 extend in a substantially axial direction, which are connected to therespective plates 6 by means ofelastic means 8, made up in particular by air springs. - As shown in figures 4 and 5, the
displacement unit 9 comprises twocrank mechanisms front part 1 and fixed connected tobuffers 10 by means of supports 16 integral with them.Crank mechanisms 9a, b are connected to each other by means of a drivenshaft 17, extending crosswise with respect to the locomotive, in order to assure the synchronism of their movements. Shaft 17 is oversized to such an extent as to have both high stiffness as well as reduced weight. - A
drive shaft 18 extends parallel to drivenshaft 17 and comprises a tubular central part 18a and twoend parts 18b made out from a solid bar, which engage withsupport 16 and on whichgear wheels 21 of achain transmission 20 are keyed.Chain 20 engages with asecond gear wheel 22, keyed on a small actuatingshaft 23. From the ends of drivenshaft 17 two radial plates extend which act as rotatingarms 19 fordrive shaft 18 with respect to the fixed part. - Small actuating
shaft 23 is mounted on asupport 24 integral withbuffers 10. At the ends of tubular part 18a ofdrive shaft 18 flanges are provided each of them bearingprotrusions 27 within which a correspondingradial tooth 28 extending from drivenshaft 17 is engaged. This connection betweendrive shaft 18 and drivenshaft 17 assures the transmission of the rotation between the two shafts and a certain clearance (in particular about 30°) between them, whose function will be explained hereinafter. - For each end of drive shaft 18 a
chain transmission 20 and a respective small actuatingshaft 23 are provided. At the end of each small actuating shaft 23 asmall opening 25 is provided on both sides of the locomotive so that adrive key 26 can be inserted by the operator. Such key presents a reference tooth 26a, in correspondance to a notch, not shown, formed on amatching jig 25a before the fixedsmall opening 25, so thatkey 26 can neither be inserted nor extracted unlessnose 2 is wholly closed or wholly open. -
Arms 29 extend radially and rigidly close to the ends of drivenshaft 17, and connecting rod means 11 engage on such arms. Eacharm 29 comprises, as shown in figure 6, a pair of plates welded to drivenshaft 17 and an articulatedjoint 30 for the respective connecting rod is provided at the end thereof. Each connectingrod 11 is connected, with the other end, to lower side-arms 14 offloating frame 4 by means of ajoint 31 and comprises astrut 32 with a C-shaped lenght 32a to avoid interference withdrive shaft 18 during the motion of the connecting rod, and a coil-spring mechanism 33 which assures the extensibility of the strut itself. In such a way it is possible to face small assembling defects which would otherwise cause damages. - By operating small actuating
shaft 23, as will be said next, drivenshaft 17 moves from a position situated overdrive shaft 18 and illustrated full-line in figure 5 towards the position, substantially overturned, illustrated in dotted line and indicated at 17a in the same figure. The angular displacement of theshaft 17 is equivalent to 190° to be at least 5° beyond the dead centers at the ends of the displacement, assuring this way the irreversibility of the motion. Anyway, for further safety a cam-roll mechanism is provided (see figure 5) comprising adisk 34 integral withdrive shaft 18 with twonotches 35 along its edge which are spaced along the circumference of 190°. Inside the notches 35 asmall roll 36 is engaged which is supported by asmall arm 37 extending fromsupport 16 and elastically abuting on the edge ofdisk 34. - The device described above works in the following way. Reference is made to figures 1, 2 and 3 where the device is schematically shown respectively in a closed position, in an intermediate backwardly retracted position, and in a completely retracted, open position.
- To
open nose 2key 26 is inserted into one ofsmall openings 25 situated on the two sides offront part 1 of the locomotive. After a first idle rotation of the key for an angle of about 50°, a following rotation of 360° causes a rotation of 190° ofdrive shaft 18, given the existing gear ratio . As a consequence of such rotation drivenshaft 17, carried byarms 19 and by the connection formed byprotrusions 27 andtooth 28 engaged between them, rotates of 190° from a position substantially overhangingdrive shaft 18 to a position substantially below it, whereassmall roll 36 is engaged in one of the twonotches 35 to stabilize the reached position. During thisrotation connecting rod 11 is trailed so that, in turn, it can trail floatingframe 4, thus translating of about 80 mm thenose 2 integral with it inside the front part of the locomotive. The translation occurs in a substantially parallel way with respect to the longitudinal axis of the locomotive because of the presence of a slide guide working betweennose 2 and fixed front part of the locomotive itself. As shown in figures 1, 2 and 3, the slide guide is formed by a pair of slides 41 (only one shown in the figures) integral withnose 2 and spaced from one another which are slidingly engaged with the edge ofopening 1a where internally protrudingdowels 42 are provided which engage, in turn, withseats 43 formed onslides 41. - At this
point nose 2 is in a backwards position with respect to the fixed part and it is possible for the operator to introduce his hand to push the nose downwardly to overcome the reaction ofair springs 8 which tend to keepnose 2 up. The sizing ofair springs 8 is such that they balance the weight ofnose 2 with slight margin whereby the rotation is mildly hindered. - After
nose 2 is rotated of about 90°, it is recessed within the front part of the locomotive and the automatic coupler is made accessible.Nose 2 must be kept firmly blocked in its opened position up to the next closure operation. To that end, as shown in particular in figures 5 and 6, a locking device is provided which comprises a pair ofpins 38 integral withnose 2 extending in mutual alignment toward the inside of the nose, and acam 39 integral with small actuatingshaft 23 to whichpins 38 engage at the end of the rotation of 90° ofnose 2 insidefront part 1 of the locomotive. In practice, when rotating along withnose 2,pins 38 abut againstcam 39 which is rotated backwards. At a certain moment the rotation ofnose 2 leadspins 38 beyond the profile ofcam 39 which moves backwards elastically, thereby lockingpins 38. The elastic member ofcam 39 is made up by two springs 40 (figure 4) coaxial with the drivengear wheel 21 ofchain drive 20. The action of thepivot 38 against thecam 39 causes a rotation of thesmall drive shaft 23 of about 50° which, given the existing gear ratio with thedrive shaft 18, causes a rotation of the latter of about 25°. However, in view of the existing clearance betweendrive shaft 18 and drivenshaft 17 due to the connection betweenprotrusions 27 andtooth 28 engaged therebetween, such rotation does not cause any displacement of theshaft 17. - The closing also occurs in two steps. From the operator point of view such closing requires only the rotation of the key, since the rotation of
nose 2 is driven by air springs 8. In fact, the first part of the rotation of the key makescam 39 rotate backwards, thus releasing thepivots 38 ofnose 2. This one therefore goes upwards while rotating aroundjoints 3 because of the action of air springs 8, untilslides 41 abuts against the edge ofopening 1a. Keeping the key onrotation displacement unit 9 is actuated, and as a consequence of an angular displacement of the drivenshaft 17 of about 190°, connectingrod 11 is translated as well as floatingframe 4 connected therewith, therebynose 2 is pushed forward. During this motion, whereasslides 41 run on the edge ofopening 1a, dowels 42 are engaged withseatings 43, thus assuring the right placing ofnose 2 with respect to opening 1a offront part 1 of the locomotive. The possibility of extracting key 26 fromsmall opening 25 assures that the closing position has been achieved. - Variations and/or modifications can be brought to the front structure for railway locomotives with a retractable door according to the present invention without departing form the scope of the invention itself, as defined in the appended claims.
