Abstract
The current invention relates to a method for monitoring a wear of a brake element (6) of a rail wagon (1) by means of a monitoring system (9, 4), said rail wagon (1) comprising a brake assembly (2) comprising said brake element (6), said brake assembly (2) further comprising a brake regulator device (7) comprising a first part (71) at a first end and a second part (72) at a second end for automatic adjusting of a clearance (13) with respect to said brake element (6), said clearance (13) relating to a braking of a wheel (3) of said rail wagon (1), said method comprising a plurality of steps.
Claims17
A method for monitoring a wear of a brake element of a rail wagon by means of a monitoring system, said rail wagon comprising a brake assembly comprising said brake element, said brake assembly further comprising a brake regulator device comprising a first part at a first end and a second part at a second end for automatic adjusting of a clearance with respect to said brake element, said clearance relating to a braking of a wheel of said rail wagon, said method comprising the steps of:
- measuring, by said monitoring system, of a dislocation of said first part with respect to said second part of said brake regulator device during said braking, for determining a current extension distance of said brake regulator device;
- comparing, by said monitoring system, of said measured dislocation to a predetermined dislocation, for determining an extension difference,
- calculating a change in the wheel diameter of said wheel or directly or indirectly retrieving a change of the wheel diameter from an internal memory comprised in said monitoring system or from an external memory, whereby the external memory is accessible by said monitoring system;
- evaluating by said monitoring system said wear of said brake element based on said extension difference and said change in the wheel diameter of said wheel,
- wherein the monitoring system is adapted to alert that a wear level relating to said wear exceeds a predetermined maximum wear level.
A monitoring system for monitoring a wear of a brake element of a rail wagon, said rail wagon comprising
- a brake assembly comprising said brake element,
- said brake assembly comprising a brake regulator device comprising a first part at a first end and a second part at a second end for automatic adjusting of a clearance with respect to said brake element,
- said clearance relating to a braking of a wheel of said rail wagon,
- said monitoring system comprising
- a sensing module configured for measuring a dislocation of said first part with respect to said second part of said brake regulator device during said braking for determining a current extension distance of said brake regulator device;
- means configured for comparing said measured dislocation to said predetermined dislocation for determining an extension difference;
- means configured for calculating a change in the wheel diameter of said wheel or retrieving the change of the wheel diameter from an internal memory comprised in said monitoring system or from an external memory, whereby the external memory is accessible by said monitoring system;
- means configured for evaluating, based on said extension difference and said change in the wheel diameter of said wheel, said wear of said brake element,
- wherein the monitoring system is adapted to alert that a wear level relating to said wear exceeds a predetermined maximum wear level.
A kit for monitoring a wear of a brake element of a rail wagon;
- said rail wagon comprising a brake assembly comprising said brake element, said brake assembly further comprising a brake regulator device comprising a first part at a first end and a second part at a second end for automatic adjusting of a clearance with respect to said brake element, said clearance relating to a braking of a wheel of said rail wagon, said kit comprising
- a sensing module configured for
- measuring a dislocation of said first part with respect to said second part of said brake regulator device during said braking for determining a current extension distance of said brake regulator device;
- communicating said measured dislocation to a receiver,
- a monitoring module configured for
- communicating with said sensing module for receiving said measured dislocation,
- comparing said measured dislocation to said predetermined dislocation for determining an extension difference,
- calculating a change in the wheel diameter of said wheel or retrieving the change of the wheel diameter from an internal memory comprised in said monitoring module or from an external memory, whereby the external memory is accessible by said monitoring module;
- evaluating said wear of said brake element based on said extension difference,
- wherein the monitoring module is adapted to alert that a wear level relating to said wear exceeds a predetermined maximum wear level.
