- the engagement element made of cast metal, which due to the complex shape of the hook-shaped
- Insertion section is advantageous, especially the
- the threaded element is preferably made of steel, which has the advantage that the threaded element with a in the usual
- Area sized threaded bolt can accommodate very high loads, so that the hook bolt according to the invention compared to a known in the art hook bolts of cast metal can absorb significantly increased lateral forces.
- the rail fastening system comprises at least one hollow sleeper with passage openings and hook bolts according to the invention, which engage with their hook-shaped insertion section into the passage openings of the at least one hollow sleeper.
- the rail fastening system further comprises angled guide plates, through which each of the threaded bolt of the hook bolt passes as well
- the threaded element consists of steel.
- a high load can be absorbed in this way with usual dimensioning of the threaded bolt.
- other materials are conceivable that are available at low cost and increased compared to cast metal
- the hook-shaped Eingriffseiement consists of gray cast iron or Kugelgrafitguss.
- the receiving space of the engagement element is designed so that the on toe shoe of the threaded element by a lateral movement in the plane perpendicular to the longitudinal axis of the threaded bolt in the receiving space can be inserted.
- Threaded element can be inserted through a horizontal displacement movement in the on imaginary space of the engagement member.
- a simple, horizontal translation movement is both easy to perform, but also has the advantage that when mounted in the rail mounting the
- Receiving shoe is pulled relative to the receiving space in a vertical upward direction, in this way, in addition to the positive connection also forms a frictional connection between the top in the installed position side of the pick-up shoe and correspondingly shaped upper, inner wall portions of the receiving space.
- Such a frictional connection has the additional advantage that automatically a relative movement between receiving shoe and receiving space is counteracted in the horizontal direction and thus an automatic release of the connection between Eingriffseiement and threaded element is prevented.
- the hook-shaped insertion portion of the engagement element on a locking lug which has a substantially oriented in a further plane perpendicular to the longitudinal axis of the threaded bolt stop surface.
- Cavity of the hollow sleeper forth seen upper wall adjacent to the passage opening abut and therefore provides additional security against inadvertent leakage the Einsteckabitess from the passage opening of the

- the hook bolt in addition to a plastic cover which extends over the support portion and arranged in the receiving space on ahmeshschuh and a
- Such a plastic cover has several advantages. On the one hand, it is used for electrical insulation, which is of great importance in relation to the use of metal sleepers. Another advantage is that the penetration of water into the hollow sleeper is prevented or at least made more difficult. The main advantage of
- plastic cover is to prevent slipping out of the threaded element and in particular the pick-up shoe from the up eraume in the unloaded state of the hook bolt.
- the plastic cover on a passage opening for the threaded bolt, but no significant displacement movement between the
- Threaded element and the engagement element allows and therefore prevents the threaded element from being able to disengage from the engagement element.
