Abstract
In a roller device (6,7) for a movable point of frog (1), including a sliding strip (18) and at least one roller (11) and at least one roller bearing (12) fixed to a stationary part of the switch, the roller(s) (11) is/are mounted on an arm (19) of a double-armed lever (10). The pivot bearing (12) of the lever (10) is arranged in a support (13) connected with a stationary part of the switch, wherein the arm (18) facing away from the roller(s) (11), of the double-armed lever (10) is pivotable against a spring (19) with adjustable spring power.
Claims23
A roller device for a movable point of frog, comprising a sliding strip,
- a double-armed lever(10),
- said double-armed lever (10) being pivotable about a pivot bearing (12) arranged in a support (13) connected with a stationary part of a switch, said double-armed lever (10) comprising a first arm (9) and a second arm (18), and
- at least one roller (11) mounted on the first arm (9) of said double-armed lever (10),
- wherein said second arm (18) faces away from said at least one roller (11) and is pivotable against a spring (19) with adjustable spring power,
- and wherein said pivot bearing (12) is arranged between said spring (19) and said at least one roller (11).
A set of roller devices for a movable point of frog, comprising a plurality of roller devices, wherein each roller device comprises
- a sliding strip,
- at least one roller (11), and
- at least one roller bearing fixed to a stationary part of a switch,
- wherein said at least one roller is mounted on a first arm (9) of a double-armed lever (10), a pivot bearing (12) of the lever (10)is arranged in a support (13) connected with a stationary part of the switch, said pivot bearing (12) defining a pivot axis for the pivoting motion of said lever (10), and a second arm (18) of the double-armed lever (10) facing away from the at least one roller (11) is pivotable against a spring (19) with adjustable spring power,
- wherein said plurality of roller devices is arranged in a manner offset in a longitudinal direction of said movable point of frog,
- wherein a lever arm ratio of said double-armed lever (10) of each of said plurality of roller devices is selected to be identical, and the first lever arm (9) of each of the plurality of roller devices is respectively shorter than the second lever arm (18), and carries the at least one roller (11).
