Estimating the term…
A frog (10) and to a method for producing such a frog, comprising wing rails (16, 18) each having at least one railhead (62, 64) and one rail web (66, 68), and comprising a frog point (12) arranged movably between the wing rails, wherein, in the region of the frog point, a wheel transfer zone extends between the frog point and the wing rail with which the frog point is in contact. Separately from the frog point (12), each wing rail (16, 18) has a portion (20, 22) which extends at least over the length of the wheel transfer zone and which is made from a forged block.
A frog (10) comprising:
A method for producing wing rails (16, 18) for a frog (10) with a movable frog tip (12), wherein at least one section (20, 22) of each of the wing rails (16, 18) is produced from a forged steel block by metal cutting processing, whereby a cant of the running surface is machined out in a region, in which the frog tip (12) contacts the wing rail section (20, 22).
The method according to claim 16, wherein an anti-derail device for the frog tip (12) is machined from the block as one piece with the wing rail section (20, 22).
