‘ANNEX LL

HOT AXLE BOX DETECTION REFERENCE DOCUMENT

Note: this Annex is also published as a Technical Document of the European Railway Agency and will be further maintained in accordance with Article 1a(4).

1.   TERMS AND DEFINITIONS

For the purposes of this Annex, the following terms and definitions apply.

Axle bearing: a bearing or bearing assembly on a rail vehicle axle that transmits a proportion of the weight of the rail vehicle directly to the wheelset.

Axle box: the structure, including for example cartridge bearing adaptor, which houses, or is in contact with, the axle journal bearing and provides an interface with the bogie and/or suspension arrangement.

Hot axle box detector (HABD):

Target zone: a defined area on the underside of an axle box that is designed to have its temperature monitored by a HABD.

Target area: the plan view dimensions, that is in the XY plane, of the target zone.

Prohibitive zone: a zone in which heat sources such as exhausts, which might influence the behaviour of a HABD, are excluded or thermally shielded.

Rolling stock coordinates: rolling stock coordinates, figure 1, are based on the right hand rule Cartesian coordinate system, where the positive X-axis (longitudinal) is along the vehicle in the direction of travel, the Z-axis is vertically upwards and the origin is at the centre of the wheelset axle. The Y-axis is the lateral axis.

Figure 1

Rolling Stock Coordinates

Wheelset: a unit comprising: an axle, two wheels and their axle bearings, or a pair of independent wheels located at the same longitudinal position and their bearings.

Heat source: a part of the rolling stock that may have a temperature above the in-service running temperature of the underside of the axle box, such as a hot load or an exhaust pipe.

2.   SYMBOLS AND ABBREVIATIONS

For the purposes of this Annex, the following symbols and abbreviated terms apply:

HABD	Hot Axle box Detector
IM	Infrastructure Manager (as defined in the TSIs)
LPZ	Longitudinal length in mm of the prohibitive zone
LTA	Longitudinal length in mm of the target area
PZ	Prohibited zone
RST	Rolling stock (as defined in TSI)
RU	Railway Undertaking (as defined in TSI)
TA	Target area
TSI	Technical Specification for Interoperability
WPZ	Lateral width in mm of the prohibitive zone

XTA	Longitudinal position of the centre of the target area relative to the centre line of the vehicle
YTA	Lateral position of the centre of the target area relative to the centre line of the vehicle

3.   ROLLING STOCK REQUIREMENTS

This section contains the requirements for the rolling stock side of the HABD interface.

3.1.   Target Zone

The target zone is an area on the underside surface of an axle box described by the intersection of the axle box with a virtual cuboid that has a horizontal cross sectional area given by the dimensions XTA and YTA using the rolling stock coordinates. The horizontal cross sectional area of the virtual cuboid is therefore congruent to the plan view area (that is in the XY plane) of the target zone, herein named the target area.

3.2.   Target area

The target area is set in space relative to the axle dimensions, and defines an area in which a HABD can focus to monitor the temperature of an axle box. Figure 2 shows the position and minimum dimensions of the target area using rolling stock coordinates.

Figure 2

Dimensions and position of the target area (TA) in the XY plane (viewed from below)

3.3.   Dimensions of the Target Area

Taking into account mechanical tolerances the target area shall:

—	have a lateral width, WTA, greater than or equal to 50 mm;

—	have a longitudinal length, LTA, greater than or equal to 100 mm.

3.4.   Position of the Target Area in the XY plane

In the XY plane the centre of the target area shall be positioned at a lateral distance, YTA, relative to the centre of the axle (or centre of a pair of wheels at the same position), where 1 065 mm is less than or equal to YTA and YTA is less than or equal to 1 095 mm. In the longitudinal axis the centre of the target area shall be congruent with the centre line of the axle.

3.5.   Visibility requirements for the Target Area

Rolling stock shall be designed with no obstruction between the target zone and the HABD that would impede or prevent the HABD from focusing within the target zone and thereby prevent a measurement of its thermal radiation.

Note

:

The design of the rolling stock axle box should aim to achieve a homogeneous temperature distribution within the target zone.

4.   OTHER MECHANICAL DESIGN REQUIREMENTS

To minimise the opportunity for a HABD to calculate a temperature from a heat source that is not an axle box, rolling stock shall be designed so that other heat sources, for example hot payload or exhaust, are not immediately adjacent to or directly above the target area position. To facilitate this no other heat source shall be located within the prohibitive zone defined in this document.

Note 1	:	If, due to the design of the rolling stock, it is possible/unavoidable for a heat source other than that of an axle box to be contained within the prohibitive zone, that heat source shall be thermally shielded to prevent erroneous temperature calculations by a HABD measuring its thermal radiation.
Note 2	:	The prohibitive zone shall be maintained for all rolling stock, including for example rolling stock with inboard bearings.

4.1.   Prohibitive Zone

The prohibited zone is defined by a rectangular area, which includes the target area, and is extended vertically to form a virtual cuboid. The dimensions of the cuboid are LPZ and WPZ in the XY plane and HPZ in the vertical axes. Figure 3 shows a possible position of the target area in the prohibitive zone using rolling stock coordinates.

The dimensions of the prohibitive zone's cuboid, taking into account mechanical tolerances, shall be:

—	lateral width, WPZ, greater than or equal to 100 mm;

—	longitudinal length, LPZ, greater than or equal to 500 mm;

—	vertical height, HPZ, starts at a point in the XY plane immediately above the HABD and ends at either the height of the target area, the height of a thermal shield or the height of the vehicle.

The position of the centre of the prohibitive zone in the X-Y plane shall be:

—	in the lateral direction, YPZ = 1080 mm ± 5 mm measured relative to the centre of the axle (or centre of a pair of wheels at the same position);

—	in the longitudinal direction it shall be congruent with the centre line of the axle ± 5 mm.
