Definitions

  • the invention relates to a system and an attachment point formed from such a system for fastening a rail for rail vehicles.
  • the invention aims at a system and an attachment point, which allows a so-called “screwless" attachment of rails for rail vehicles.

  • Such commonly integrally formed rails have a rail head, on the free upper side of which the track for the rail wheels of the rail vehicle is formed, a web which carries the rail head, and a foot on which the web stands and which protrudes on both sides of the web, to ensure a sufficiently wide support surface for a tipping safe support.
  • Screwless rail fasteners of the type in question here are based on the idea of anchoring a suitable support element in the respective substrate supporting the rail fastening point and of clamping a spring element on this support element in such a way that it exerts an elastic hold-down force on the rail to be fastened.
  • the interacting components of the system or attachment point are designed so that the spring element is held in its operative position, without the need for additional components are required.
  • the support element usually has a mounting portion, which is embedded in the ground, and a support portion on which are formed form elements which serve as stops or supports for the bracing of the spring element.
  • the spring element is here shaped so that it is so twisted or bent by fixing to the respective mold elements that it exerts a resilient compressive force in the direction of the ground on the rail.
  • the spring elements of screwless Schienenbefest Trentsyaken for this purpose are usually bent in a continuous jump-free train of a wire, which consists of a spring steel.
  • a system for screwless mounting a rail for a rail vehicle on a ground comprises a spring element, which is bent from a spring wire and, starting from its one end successively a bearing portion, a first curved portion which is connected to the bearing portion, a hold-down portion which is connected to the first curve portion and oriented in opposite directions to the bearing portion, and a second curved portion connected to the hold-down portion and curved toward the bearing portion, the hold-down portion being adapted, in use, to rest on an upper surface of a leg of the rail to be fastened.

In this way, the insulating element can thus be pre-assembled captive on the spring element.

  • a plate 6 is placed between the attachment points B1, B2 on the substrate UO, which is made of an elastic material and ensures in a conventional manner a defined, directed in the direction of gravity compliance in the contact area of the rail S. Subsequently, the rail S is placed and the respective spring element 4 is pivoted in the direction of the rail S.
  • the inclined surface 2m allows a collision-free movement of the spring element 4, even if the insulating element 5 is pre-assembled at its hold-down section 4c.
  • the clamping tool 7 has a claw 7a with tines 7b, 7c which are bent outwards in such a way that, when the clamping tool 7 is attached to the spring element 4, it is guided from the side assigned to the holding-down section 4c to those beyond the outer side surfaces of the leg sections 3b, 3c protruding end portions of the bearing portion 4a of the spring element 4 engage.
  • the clamping tool 7 has a nose 7d, which is shaped and arranged so that it sits on the free end section of the locking section 4e when the teeth 7b, 7c are attached to the bearing section 4a.
  • a stem 7e provided on the clamping tool 7 about the axis formed by the bearing section 4a
  • the locking section 4e is now pivoted by corresponding deformation, in particular of the second curved section 4d, so that it is slidingly moved along the sliding surface 2k past the projection 2i, until it hooks on the underside of the projection 2i of the locking head 2b and is held securely there in a residual position.
  • the locking head 2b seated in the space bounded by the locking section 4e, the second curve section 4d and a section of the hold-down section 4c provides a guide by which the spring element 4 is fixed in the longitudinal and transverse direction of the rail S.
  • the locking section 4e extending beyond the hold-down section 4c when the spring element 4 is fully assembled forms a stop by which, in the sense of a tilt protection, the rail S is not too far from the ground even under unfavorable conditions under the load of a rail vehicle passing over the rail fastening SB U takes off.
  • the clamping tool 7 can of course be designed as a toggle mechanism or the like in order to apply greater deformation forces during pivoting of the locking portion 4e in its position of use can.
  • another tool 8 which also has a claw 8a with tines 8b, 8c.
  • the claw 8a is pivotally mounted on a support body 8b of the tool 8 and formed so that it can engage around with their teeth beyond the projection 2i of the locking head 2b end portions of the locking portion 4e.
  • the support body 8b in this case has a nose 8c, via which the tool 8 is supported laterally on the associated leg section 3b of the guide plate 3 and on the substrate U when the claw 8a is coupled to the locking section 4e.
  • pivoting the tool 8 about the axis formed by the support point of the nose 8c pivot axis 8d attached to the support body 8b of the locking portion 4e is laterally pulled out of its rest position under the projection 2i until it can pivot freely upwards and the spring element 4 is relaxed ,
