Definitions
- the invention relates to a clutch support for a telpuffer clutch with a rail vehicle, the clutch support is particularly suitable for a locomotive.
- the coupling support comprises a first holding plate and a second holding plate, with which the coupling support can be fastened to a vehicle body of the rail vehicle.
- the coupling support comprises a base plate arranged between the holding plates and a cross bar arranged between the holding plates, which is arranged above the base plate and is resiliently coupled to the base plate.
- the crossbar can serve to support a coupling shaft of a central buffer coupling, the central buffer coupling having a coupling shaft articulated on the vehicle body and carrying a coupling head.
- the invention relates to a central buffer coupling and a rail vehicle, in particular a locomotive, each of which contain such a coupling support.
- the crossbar is used to set a certain height of the coupling head.
- the coupling heads To couple two center buffer clutches, the coupling heads must be arranged at a matching height so that the clutches can engage in one another.
- the coupling shaft When driving over a crest, the coupling shaft would now result in high forces on the crossbeam, since the coupled clutches would be arranged lower relative to the vehicles during such a journey than when traveling in one plane.
- the resilient arrangement of the crossbar ensures that the coupling shaft can push the crossbar down.
- the crossbeam must be movable to a certain extent on the one hand, but on the other hand, on the whole, be fixed at its position between the retaining plates.
- the crossbar is fixed in that the crossbar has guide grooves in which the holding plates engage in a form-fitting manner.
- the crossbar is movable along a spring direction and is guided laterally to it.
- the central buffer coupling or the coupling shaft of the central buffer coupling exerts a lateral force on the crossbeam.
- driving over a crest or through a depression causes the cross bar to move along the spring direction. Both together lead to friction on the guide grooves or the retaining plates.
- Vertical stops can be provided with which a height of the crossbeam can be set.
- the invention has for its object to enable movement of the crossbar along the spring direction and since to minimize friction, in particular a rela tive movement between the crossbar and vertical stops to be minimized or excluded. As a result, additional maintenance and repair costs can be reduced or avoided without having to accept additional costs in production and assembly.
- the clutch support has a first rocker arm and a second rocker arm, which are arranged on the base plate.
- a first pivot point of the first rocker arm is arranged below the crossbar, a second pivot point of the second rocker arm is also arranged below the crossbar.
- the first pivot and the second pivot are connected to the base plate.
- a first upper part of the first rocker arm is connected to the crossbar with an articulated connection.
- a second upper part of the second rocker arm is connected to the crossbar by means of a second articulated connection.
- the reduced friction between the crossbeam and the vertical stops increases the lifespan of the components used, which means that maintenance and repair costs can be reduced.
- a rocker arm in the sense of the present invention is an element which is rotatably mounted at one point about an axis and otherwise cannot be moved further at this point.
- This point at which the rocker arm is rotatably supported represents the first pivot point of the first rocker arm or the second pivot point of the second rocker arm.
- the first rocker arm and the second rocker arm are thus rotatable about the first pivot point or the second pivot point, but otherwise not movable with respect to the base plate. Due to the articulated connections with which the upper parts of the rocker arms are connected to the crossbeam, movement of the crossbeam towards the base plate is made possible and movement away from the base plate is restricted.
- the crossbeam can be adequately fixed on the one hand between the retaining plates and on the other hand can be moved towards the base plate, for example when the rail vehicle is traveling through a cup. Due to the proposed fixation of the crossbeam by means of rocker arms and articulated connections, the crossbeam can be moved much more easily along the spring direction, since due to the rotatable mounting of the rocker arms in the pivot point and the mounting by the articulated connections, significantly less friction occurs. This also leads to significantly reduced material wear and thus to significantly lower maintenance costs.
- the articulated connections each form a vertical stop for the crossbeam.
- a spring is arranged between the base plate and the crossbar.
- more than one spring can also be arranged. It can be provided that the movement of the crossbar away from the base plate leads to relaxation of the spring and the movement of the crossbar towards the base plate leads to tensioning of the spring. This is particularly the case when the spring between the base plate and the crossbar is provided with a voltage.
- the pretension can be designed such that the crossbar is pressed into an upper position due to the pretension, the upper position being defined by the restriction of the movement of the crossbar due to the articulated connections. The crossbeam can thus be moved towards the base plate while accepting further tensioning of the spring, but not further away from the base plate beyond the upper position. This leads to a coupling support that is suitable for a central buffer coupling.
- a bias of the spring is adjustable, whereby the upper position of the Querbal kens can be adjusted. This can be used to adjust the height of the central buffer coupling to different heights due to different operating conditions.
- the first articulated connection has a bolt guided in an elongated hole. Through the elongated hole, movement of the crossbar away from the base plate is restricted, since at a certain point the bolt abuts a stop of the elongated hole. A movement of the crossbeam towards the base plate is possible due to the nature of the elongated hole.
- the slot on the crossbar is arranged and the bolt on the first rocker arm. This enables the rocker arm to be easily realized, since it only has to have a pin at the pivot point for placement within the elongated hole.
- the elongated hole is arranged on the first rocker arm and the bolt on the crossbar. This advantageously results in a compact arrangement of rocker arm and crossbar. An end of the elongated hole of the first rocker arm facing away from the first pivot point can serve as a stop in order to restrict a further movement of the crossbeam upwards due to the bolt.
- the first rocker arm has an adjustable vertical stop.
- An available length of the elongated hole can be changed using the adjustable vertical stop.
- a different bias of the springs and a position of the crossbar can advantageously be set.
- the first rocker arm has a threaded rod.
- the threaded rod is passed through an opening in the crossbeam.
- a nut above the opening is attached to the threaded rod in such a way that the threaded rod, the opening and the nut form the first articulated connection.
- the nut has a thread protector, the thread protector having an internal thread matching the threaded rod and being guided through the opening.
- the first rocker arm has a threaded rod.
- a ball joint is connected to the crossbeam and forms the first articulated connection.
- the ball joint is movable along the threaded rod, the movement of the crossbar away from the base plate being restricted due to a nut arranged on the threaded rod.
- the ball-and-socket joint enables a particularly frictionless first articulated connection.
- the nut has a thread protector, the thread protector having an internal thread matching the threaded rod and being guided through the ball joint.
- the crossbar is fixed with a nut
- the nut is fixed with a lock nut
- the crossbar has a Gleitplat te, which is arranged on a side of the crossbar facing away from the base plate.
- the coupling shaft of a central buffer coupling can be moved along this sliding surface.
- the holding plates each have a predetermined breaking point. This can serve to improve the crash safety of the central buffer coupling.
- the second rocker arm and the second articulated connection can be designed analogously to the first rocker arm and the first articulated connection. Alternatively, it is possible to carry out the first articulated connection and the second articulated connection in different execution forms.
- the first articulated connection can for example be designed as an elongated hole with bolts, while the second articulated connection consists of threaded rod, opening and nut. Any combinations of the mentioned embodiments are possible and conceivable.
- the invention comprises a central buffer coupling with one of the mentioned coupling supports.
- the Mittelpuf ferkupplung also has a coupling shaft and a coupling head arranged on the coupling shaft.
- the coupling shaft can be hinged to a vehicle body of the rail vehicle.
- the clutch shaft is supported by the crossbar of the clutch support.
- the invention comprises a rail vehicle with a coupling support according to one of the aforementioned embodiments, the coupling support being fastened to the rail vehicle by means of the holding plates.
- the rail vehicle can have a central buffer coupling, which is also attached to the rail vehicle and has a coupling shaft and a coupling head arranged on the coupling shaft, wherein the coupling shaft can be supported by the crossbar of the coupling support.
