SPECIFICATIONS

General

The CCD shall be so designed, constructed and assembled such that a vehicle fitted with the CCD
conforms to the requirements of this Regulation under normal conditions of road use. The cou-
pling devices themselves must comply with the technical requirements of Regulation No 55.
Additional forces which may be caused by the assembled CCD in operation shall be taken into
account.

5.1.2.

The operation of the CCD shall be automatic. Even the reverse movement of the close-coupled
combination must be possible without any manual action at the CCD.

5.1.3. (1)

In particular, the CCD shall be so designed, constructed and assembled so as to be resistant to
all stresses, corrosion and ageing to which it may be subjected (e.g. vibration, humidity, extreme
temperatures).

5.1.4.

The CCD shall enable vehicles to travel in a straight line on a level road, without any abnormal
effort being applied to the steering control, either forwards or in reverse.

5.1.5.

System failures

5.1.5.1.

Any power system failure and/or control system failure of the CCD, while the vehicle is run-
ning, shall cause the coupling to extend and remain in that position. Separation of the towing
vehicle and trailer must be prevented by mechanical means under all conditions of use.

5.1.5.2.

Any power system and/or control system failure must be indicated to the driver by an acoustic
and an optical signal.

5.1.6.

5.1.7.

When the vehicles are stationary no uncontrolled movement of the CCD may occur under any
circumstances including long term uphill parking.

Non-automatic movement of the CCD may be possible only while the towing vehicle is station-
ary. An instruction to apply the parking brake of the towing vehicle shall be permanently
attached to the control unit.

5.1.7.1.

This operation shall be controlled by means of a dual control unit.

5.1.7.2.

5.1.7.3.

5.1.7.4.

This control unit must be fitted outside the driver’s cabin and shall be situated in such a position
that the operator is not endangered by the movement of the trailer and can see the danger area
between the vehicles at a glance.

It must not be possible to lock the control unit in the operating position or operate it
unintentionally.

The movement of the trailer shall take place without jolting, at a speed of not more than
50 mm/sec.

5.1.7.5

Release of a control must stop the movement immediately.

(1) Until uniform test procedures have been agreed, the manufacturers shall provide the Technical Services with their test

procedures and results.

L 351/48

5.1.8.

Forward movement of the towing vehicle shall not result in rearward movement of the trailer in
relation to the road surface.

5.1.9.

5.1.10.

5.1.11.

Rearward movement of the trailer of not more than 30 mm is permitted only for switch and
react purposes.

The CCD must return to its shortest normal straight ahead operating position following relative
angular movement between towing vehicle and trailer, in accordance with Annex IV.

Operation of the CCD shall not interfere with the dynamic stability of the combination. This
requirement shall be checked during the tests described in Annex IV.

The CCD shall be designed so as to enable the vehicles to be coupled or uncoupled. All coupling
operations shall be automatic, including the mechanical controls and the parts subject to tow-
ing and/or steering forces. Correct engagement of the positive locking system must be indicated
or be easily visible from the side of the vehicle alongside the coupling device. Otherwise, a
remote indication must be installed in the driver’s cabin. Manual coupling of control and power
supply lines is permitted provided the connections are readily accessible from a standing posi-
tion and the combination can be safely driven, without these lines being connected.

5.1.12.

The CCD when engaged must itself provide at least the following angular movement:

horizontal

For hydraulic or pneumatic CCD’s, an optical signal shall indicate that the CCD is about to reach
its maximum extension. This signal may be the same as the optical signal mentioned in para-
graph 5.1.5.2.

The CCD shall be designed such that when coupling at an angle between the towing vehicle and
trailer different from that when uncoupled, unintentional movement of the trailer or incorrect
functioning of the CCD does not occur.

A plate specifying the maximum mass of the towing vehicle and the trailer, all lubrication points
and the frequency of lubrication shall be affixed such that it is clearly visible even when the trailer
is coupled.

conformity with the procedures approved by the competent authority;

ensure that any collecting of samples or parts giving evidence of non-conformity in the type of
test in question shall give rise to another sampling and another test. All the necessary steps shall
be taken to re-establish the conformity of the corresponding production.

The competent authority which has granted type approval may at any time verify the confor-
mity control methods applicable to each production unit.

In every inspection, the test books and production survey records shall be presented to the vis-
iting inspector.

The inspector may take samples at random to be tested in the manufacturer’s laboratory. The
minimum number of samples may be determined in the light of the results of the manufactur-
er’s own checks.

Where the quality level appears unsatisfactory or when it seems necessary to verify the validity
of the tests carried out in application of paragraph 7.4.2 above, the inspector shall select samples,
to be sent to the technical service which has conducted the type approval tests.

The competent authority may carry out any test prescribed in this Regulation.

The normal frequency of inspections authorized by the competent authority shall be once every
two years. In the case where negative results are recorded during one of these visits, the com-
petent authority shall ensure that all necessary steps are taken to re-establish the conformity of
production as rapidly as possible.

ANNEX IV

REQUIREMENTS CONCERNING TESTS AND PERFORMANCE (1)

(See paragraph 5.1.10)

1.

CCD RECOVERY DISTANCE

1.1.

The towing vehicle/trailer combination shall be driven, from a straight ahead position, around a bend having
an outside radius of 12.5 metres and stopped when the towing vehicle has turned through an angle of 90° (yaw-
angle). The combination shall then be accelerated as quickly as possible up to a speed of 30 ± 2 km/h and be
maintained at this ed until completion of the test. Full retraction of the CCD must have taken place within
150 metres from the acceleration start position (see Figure 1 below).

This test shall be conducted in both left and right directions.

Figure 1

Note: Compliance with these requirements does not guarantee that the overall length of the vehicle combina-

tion is legal in all driving conditions.

1.2.

The technical service shall verify that some retraction of the CCD takes place all the time the towing vehicle is
moving forward.

2.

STABILITY OF THE COMBINATION

For the approvals under Sections I and II, the stability performance shall be measured during road tests con-
ducted in the following conditions:

(1) For the purposes of approvals under Section II, the technical service may take into account tests conducted for the purposes of Section I.

2.1.

TEST CONDITIONS

2.1.1.

Loading conditions

2.1.1.1.

The vehicles must be laden, the distribution of mass among the axles being that stated by the manufacturers of
the vehicles; where provision is made for several arrangements of the load on the axles, the distribution of the
maximum mass among the axles must be such that the mass on each axle is proportional to the maximum per-
missible mass for each axle.

2.1.1.2.

The height of the centre of gravity of the vehicles shall be at least 1,7 metres.

The actual loading condition shall be specified in the test report. For vehicles designed for use with a centre of
gravity lower than 1,7 metres, the test may, at the discretion of the approval authority, be conducted at the
lower figure.

In this case the maximum centre of gravity height shall be stated on the information plate required by para-
graph 5.1.1.5.

2.1.2.

The test must be carried out at the speeds prescribed for each type of test.

If the maximum design speed of a vehicle is lower than the speed pre-scribed for a test, the test shall be per-
formed at the vehicle’s maximum speed.

2.1.3.

The road must be level and must have a surface affording good adhesion;

2.1.4.

The tests must be performed when there is no wind liable to affect the results;

2.1.5.

At the start of the tests, the tyres must be cold and at the pressure prescribed by the manufacturer of the vehicles
or tyres for the load actually borne by the wheels when the vehicles are stationary; substantially -new tyres shall
be used.

2.1.6.

The prescribed performance must be obtained without self amplifying reactions, without deviation of the
vehicles from their course, and without unusual vibration in the steering and coupling system.

2.2.

STRAIGHT LINE STABILITY TEST

2.2.1.

Vehicles shall be tested at a speed of 85+5/–0 km/h and remain aligned. During the test, it must be possible to
travel along a straight section of the road without unusual steering correction by the driver.

2.2.2. (1)

An emergency straight line braking test from a speed of 60 km/h to rest at a mean fully developed deceleration
of at least 4 m/s2 shall not cause the combination to deviate outside a lane 3,5 metres wide.

2.2.3.

Starting from rest, a forward acceleration of at least 2 m/s2 shall not cause any movement between the vehicles
of a degree likely to cause the driver difficulty in controlling the vehicle combination. (If the acceleration pre-
scribed for this test cannot be reached by a vehicle combination, the test shall be performed with the maximum
acceleration available).

2.2.4.

No permanent deformation shall take place during the above tests.

2.3.

CHANGE OF LANE

2.3.1.

2.3.2.

A simulated overtaking manoeuvre, as defined in the appendix, conducted at a progressively increasing speed
up to 80 km/h, shall not cause the driver any difficulty in controlling the combination.

At a speed of 20 km/h steering from one side of the track to the other alternately at least 3 times by turning the
steering wheel as fast and as far as possible, no contact between the vehicles or damage to the CCD shall occur
(track width is 10 metres).

(1) The technical service shall take account of the predominance setting of the combination.

CIRCULAR MOVEMENT

3.1.

3.2.

Starting from rest and a straight ahead position, the combination shall be driven around a curve of 25 m radius
to a speed of 20 km/h at an acceleration of 2 ± 10 % m/s2. This shall not cause any movement between the
vehicles of a degree likely to cause the driver difficulty in controlling the vehicle combination.

With the towing vehicle and trailer having adopted a steady state, turn so that the front outside edge of the tow-
ing vehicle describes a circle of radius of 25 m, at a constant speed of 5 km/h. The circle described by the rear-
most outer edge of the trailer shall be measured. This manoeuvre shall be repeated under the same conditions
but at a speed of 25 km/h ± 1 km/h.

During these manoeuvres, the rearmost outer edge of the trailer, travelling at a speed of 25 km/h ± 1 km/h,
shall not move outside the circle described during the manoeuvre at a constant speed of 5 km/h by more than
0,70 m (see Figure 2 below).

Figure 2

3.3.

No part of the trailer must move more than 0,5 m beyond the tangent to a circle with a radius of 25 m when
towed by a vehicle leaving the circular path along the tangent while maintaining the speed of 25 km/h. This
requirement must be met from the point the tangent meets the circle to a point 40 m along the tangent. After
that point the trailer must travel without excessive deviation or unusual vibration in its steering equipment
(see Figure 3 below).

L 351/61

3.4.

Any motor vehicle or combined vehicle which is in motion must be able to turn within a swept circle having
an outer radius of 12,50 m and an inner radius of 5,30 m. The test shall be conducted in both left and right
directions. No part of the combination, where it penetrates the circle from a tangent, may overlap that tangent
by more than 0,8 m beyond the point of intersection (see Figure 4 below).

SLOPES

When positioned longitudinally in line and in the normal operation position:

There shall be no unintentional contact between any part of the towing device and the towing vehicle or trailer
when the vehicles are positioned at a relative vertical angle of 6°.

4.1.2.

No contact shall occur between the bodies of the towing vehicle and trailer at a relative vertical angle of 5°.

4.2.

The requirements of paragraphs 4.1.1 and 4.1.2 may be verified by calculation at the discretion of the technical
service.
