Item 4: Wheelbase - Dimension referred to in point 6.4.1 of Standard ISO 612:1978

COC, Wheelbase, Axle Spacing Wurst, BMVIT 3

6.4.1 Motor vehicle or trailer wheel space

The distance between the perpendicular lines constructed to the longitudinal median plane (of the vehicle) (see clause 5) from the previously defined points A or B corresponding to two consecutive wheels situated on the same side of the vehicle. NOTES 1 If the values of right and left wheel spaces are

different, both dimensions are stated, separated by a dash, the first corresponding to the left wheels.

2 For vehicles with three or more axles, the wheel spaces between consecutive wheels are indicated, going for the foremost to the rearmost wheel: the total wheel space for right or for left is the sum of these distances.

Item 4.1: Axle Spacing - Footnote (e) as amended in Reg 1171/2014 („Multistage“):

• “(e) Entries 4. and 4.1 shall be completed in accordance with definitions 25 (Wheelbase) and 26 (Axle spacing) of Regulation (EU) 1230/2012 respectively”

- Definition in Article 2 (26) of 1230/2012: • (26) ‘axle spacing’ means the distance between two consecutive axles referred to

in point 6.4 of Standard ISO 612:1978 in the case of vehicles with more than two axles; where the vehicle is fitted with two axles only, or in the case of a semi-trailer, a drawbar trailer or a rigid drawbar trailer, the axle spacing referred to in point 6.4.2 of Standard ISO 612:1978 has the meaning of ‘wheelbase’ as defined in point (25);

[…] NOTES 1 If the values of right and left wheel spaces are different […] 2 For vehicles with three or more axles, the wheel spaces between consecutive wheels are indicated, going for the foremost to the rearmost wheel: the total wheel space for right or for left is the sum of these distances.

Other remarks - Wheelbase and Axle Spacing refers always to the axles themselvses

- Newer to an „Effective Wheelbase of Axle Group(s)“ as required for manoeuvrability assessment

- Whether or not with a axle distance of less or more than 1000 mm

- Different terms used in ISO and 1230/2012: Wheel space (ISO) <-> Wheelbase (EU) Wheel Space (ISO) <-> Axle Spacing (EU)

COC, Wheelbase, Axle Spacing Wurst, BMVIT 14

Consequences: - Wheelbase:

- Semi Trailer: 6300 mm

- Centre Axle Trailer: 5000 mm

COC, Wheelbase, Axle Spacing Wurst, BMVIT 15

Definition in Article 2 (25) of 1230/2012: (25) ‘wheelbase’ means the following:

(a) the dimension referred to in point 6.4.1 of Standard ISO 612:1978;

(b) for a centre-axle trailer with one axle, the horizontal distance between the vertical axis of the coupling and the centre of the axle;

(c) for a centre-axle trailer with more than one axle, the horizontal distance between the vertical axis of the coupling and the centre of the first axle;

!

Clarification Required: - Wheelbase:

- Four Axle Motor Vehicle: 1300 mm = total wheel space acc. to Note in 6.4.1 NOT taken as wheelbase

or

- Four Axle Motor Vehicle: 6700 mm = total wheel space acc. to Note in 6.4.1 taken as wheelbase

Proposal 1: - Amend Definitions in Article 2 (25) and (26) of 1230/2012 as follows:

COC, Wheelbase, Axle Spacing Wurst, BMVIT 17

Old text New Text (25) ‘wheelbase’ means the following:

(a) the dimension referred to in point 6.4.1 of Standard ISO 612:1978;

(b) for a centre-axle trailer with one axle, the horizontal distance between the vertical axis of the coupling and the centre of the axle;

(c) for a centre-axle trailer with more than one axle, the horizontal distance between the vertical axis of the coupling and the centre of the first axle;

(25) ‘wheelbase’ means the following: (a) for motor vehicles and drawbar trailers the

horizontal distance between centres of the first and the last axle;

(b) for centre-axle trailers, semi-trailers and rigid drawbar trailers the distance between the vertical axis of the coupling and the centre of the last axle;

(26) ‘axle spacing’ means the distance between two consecutive axles referred to in point 6.4 of Standard ISO 612:1978 in the case of vehicles with more than two axles; where the vehicle is fitted with two axles only, or in the case of a semi-trailer, a drawbar trailer or a rigid drawbar trailer, the axle spacing referred to in point 6.4.2 of Standard ISO 612:1978 has the meaning of ‘wheelbase’ as defined in point (25);

(26) ‘axle spacing’ means the distance between the centres of two consecutive axles referred to in point 6.4 of Standard ISO 612:1978; for centre-axle trailers, semi-trailers and rigid drawbar trailers the first axle spacing is the horizontal distance between the vertical axis of the coupling and the centre of the first axle;

Proposal 2: - Amend Annex IV, Models for complete, completed and incomplete vehicles for Categories O1, O2, O3 and O4, point 4.1 as follows

- NB: footnote (e) missing in 4.1, but 4.1 referred in Footnote (e)

COC, Wheelbase, Axle Spacing Wurst, BMVIT 18

Old text 4.1. Axle spacing: 1-2: … . . . . mm 2-3: … . . . . mm 3-4: …. . . . . mm

New Text 4.1. Axle spacing (e): 0-1: … . . . . mm 1-2: … . . . . mm 2-3: … . . . . mm 3-4: …. . . . . mm

Proposal 3: - Bring in line “retractable axle and “lift axle” in information documents:

COC, Wheelbase, Axle Spacing Wurst, BMVIT 19

Directive 2007/46/EC, Annex I and III Reg 1230/2012, Annex V Part A

NB: in the COC it’s “31. position of lift axle(s)”. But at least in the information documents the same term should be used.
