Proposal for a

DIRECTIVE OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

on braking devices of wheeled agricultural or forestry tractors

(Codification)

EXPLANATORY MEMORANDUM

1. In the context of a people’s Europe, the Commission attaches great importance to simplifying and clarifying the law of the Union so as to make it clearer and more accessible to the citizens, thus giving them new opportunities and the chance to make use of the specific rights it gives them.

This aim cannot be achieved so long as numerous provisions that have been amended several times, often quite substantially, remain scattered, so that they must be sought partly in the original instrument and partly in later amending ones. Considerable research work, comparing many different instruments, is thus needed to identify the current rules.

For this reason a codification of rules that have frequently been amended is also essential if the law is to be clear and transparent.

2. On 1 April 1987 the Commission decided[1] to instruct its staff that all acts should be codified after no more than ten amendments, stressing that this is a minimum requirement and that departments should endeavour to codify at even shorter intervals the texts for which they are responsible, to ensure that their provisions are clear and readily understandable.

3. The Conclusions of the Presidency of the Edinburgh European Council (December 1992) confirmed this[2], stressing the importance of codification as it offers certainty as to the law applicable to a given matter at a given time.

Codification must be undertaken in full compliance with the normal procedure for the adoption of acts of the Union.

Given that no changes of substance may be made to the instruments affected by codification , the European Parliament, the Council and the Commission have agreed, by an interinstitutional agreement dated 20 December 1994, that an accelerated procedure may be used for the fast-track adoption of codification instruments.

4. The purpose of this proposal is to undertake a codification of Council Directive 76/432/EEC of 6 April 1976 on the approximation of the laws of the Member States relating to the braking devices of wheeled agricultural or forestry tractors[3] . The new Directive will supersede the various acts incorporated in it[4]; this proposal fully preserves the content of the acts being codified and hence does no more than bring them together with only such formal amendments as are required by the codification exercise itself.

5. The codification proposal was drawn up on the basis of a preliminary consolidation , in 22 official languages, of Directive 76/432/EEC and the instruments amending it, carried out by the Publications Office of the European Union, by means of a data-processing system . Where the Articles have been given new numbers, the correlation between the old and the new numbers is shown in a table contained in Annex VII to the codified Directive.

1.1.10. tyre dimensions (braked axles).

1.2. Braking device

‘Braking device’ means a combination of parts whose function is progressively to reduce the speed of a moving tractor or to bring it to a halt, or to keep it stationary if already halted. These functions are specified in point 4.1.2. A device shall consist of the control, the transmission and the brakes themselves.

1.3. Graduated braking

‘Graduated braking’ means braking during which, on either the application or release of the brakes, within the normal range of operation of the device:

1.3.1. the driver can at any time increase or reduce the braking force through action on the control,

1.3.2. the braking force acts in the same direction as the action on the control (monotonic function),

1.3.3. it is easy to make a sufficiently fine adjustment to the braking force.

1.4. Control

‘Control’ means the part actuated directly by the driver to supply to the transmission the energy required for braking or controlling it. That energy may be the muscular energy of the driver, or energy from another source controlled by the driver, or a combination of these various kinds of energy.

1.5. Transmission

‘Transmission’ means the combination of components situated between the control and the brake and connecting the two operationally. The transmission may be mechanical, hydraulic, pneumatic, electrical, or mixed. Where the braking power is derived from or assisted by a source of energy independent of the driver but controlled by him, the reserve of energy in the device shall likewise be regarded as part of the transmission.

1.6. Brake

‘Brake’ means the component in which the forces opposing the movement of the tractor develop. It may be a friction brake (when the forces are generated by the friction between the two parts of the tractor moving relatively to one another), an electrical brake (when the forces are generated by electro-magnetic action between two parts of the tractor moving relatively to but not in contact with one another), a fluid brake (when the forces are generated by the action of a fluid situated between two parts of the tractor moving relatively to one another), or an engine brake (when the forces are derived from a controlled increase in the braking action of the engine transmitted to the wheels).

A device which mechanically locks the tractor's transmission but which cannot be used when the tractor is in motion shall be regarded as a parking brake.

1.7. Different types of braking devices

‘Different types of braking devices’ means equipment which differs in such essential respects as:

1.7.1. the characteristics of one or more components, for example the material, shape or size,

1.7.2. the arrangement of the components.

1.9. Continuous braking

‘Continuous braking’ means the braking of combinations of vehicles through an installation having the following characteristics:

1.9.1. a single control which the driver actuates progressively, by a single movement, from his driving seat,

1.9.2. the energy used for braking the vehicles constituting the vehicle combination is supplied from the same source (which may be the muscular energy of the driver),

1.9.3. the braking installation ensures simultaneous or suitably phased braking of each of the constituent vehicles of the combination, whatever their relative positions.

1.10. Semi-continuous braking

‘Semi-continuous braking’ means the braking of combinations of vehicles through an installation having the following characteristics:

1.10.1. a single control which the driver can actuate progressively, by a single movement, from his driving seat,

1.10.2. the energy used for braking the vehicles constituting the vehicle combination is supplied from several different sources (one of which may be the muscular energy of the driver),

1.10.3. the braking installation ensures simultaneous or suitably phased braking of each of the constituent vehicles of the combination, whatever their relative positions.

1.11. Independent power-operated braking

‘Independent power-operated braking’ means the braking of combinations of vehicles by means of devices having the following characteristics:

1.11.1. a tractor brake control which is independent of the towed vehicle brake control; the latter being in all cases mounted on the tractor in such a way as to be easily actuated by the driver from his driving seat,

1.11.2. the muscular energy of the driver is not the energy used for braking the towed vehicles.

1.12. Independent braking

‘Independent braking’ means the braking of combinations of vehicles by means of devices having the following characteristics:

1.12.1. a tractor brake control which is independent of the trailer brake control, the latter being in all cases mounted on the tractor in such a way as to be easily actuated by the driver from his driving seat,

1.12.2. the muscular energy of the driver is the energy used for braking the towed vehicles.

1.13. Automatic braking

‘Automatic braking’ means braking of the towed vehicle or vehicles occurring automatically in the event of separation of components of the combination of coupled vehicles, including such separation through coupling breakage, without the braking effectiveness of the remainder of the combination being substantially reduced.

1.14. Inertia braking

‘Inertia braking’ means braking by utilising the forces generated by the trailer closing up on the tractor.

ê 76/432/EEC (adapted)

1.15. Laden tractor

‘Laden tractor’ means, except where otherwise stated, a tractor laden to its ‘maximum Ö mass Õ ’.

1.16. Maximum Ö mass Õ

‘Maximum Ö mass Õ ’ means the maximum technically permissible Ö mass Õ stated by the manufacturer (this Ö mass Õ may be higher than the ‘authorized maximum Ö mass Õ ’).

1.17. Unladen tractor

‘Unladen tractor’ means the tractor in running order, with full tanks and radiators, with a driver of a mass of 75 kg, but without passengers, optional accessories or load.

1.18. Unladen Ö mass Õ

‘Unladen Ö mass Õ ’ means the Ö mass Õ of the unladen tractor.

ê 76/432/EEC

è1 96/63/EC Art. 1 and Annex, pt 1

4. CONSTRUCTION AND FITTING REQUIREMENTS

4.1. General

4.1.1. Braking device

4.1.1.1. The braking device must be so designed, constructed and installed as to enable the tractor in normal use to comply with the undermentioned requirements, despite any vibration to which it may be subjected.

4.1.1.2. In particular, the braking device must be so designed, constructed and installed as to resist corrosion and the effects of ageing during service, which could lead to a sudden loss of braking efficiency.

4.1.2. Functions of the braking device

The braking device defined in point 1.2 must meet the following conditions:

4.1.2.1. Service brakes

4.1.2.1.1. The service brake must enable the motion of the tractor to be controlled and the tractor to be stopped safely, quickly and efficiently, at any design speed and with the authorized load on both up and down gradients. It must be possible to regulate its action. These conditions are deemed to be fulfilled if the requirements of Annex II are satisfied.

The driver must be able to apply the service brake from his seat and retain control of the steering device on the tractor with at least one hand. The service brake of the tractor may comprise right and left hand devices. It must be possible to connect them up so that they can be actuated in a single operation, and possible to disconnect them again.

Each device, right or left hand, must have a system of adjustment, which may be either manual or automatic, enabling the balance of the brakes to be easily restored.

4.1.2.2. Parking brakes

4.1.2.2.1. The parking brake must enable the tractor to be held stationary on an up or down gradient even in the absence of the driver, the working parts being then held in the locked position by a purely mechanical device. This may be achieved by means of a brake acting on the transmission. The driver must be able to apply the parking brake from his seat; a repeated action to obtain the required performance is permitted.

4.2. Characteristics of braking devices

4.2.1. The set of braking devices with which a tractor is equipped must satisfy the requirements laid down for the service and parking brakes.

4.2.2. The service and parking brake devices may have common components, provided that they fulfil the following conditions:

4.2.2.1. there must be at least two controls, independent of each other and readily accessible to the driver from the driving seat; it must be possible for this requirement to be met even when the driver is wearing a safety belt,

4.2.2.2. in the event of a breakage of any component of the braking device other than the brakes (as defined in point 1.6) or of any other failure of the service braking device (malfunction, partial or total exhaustion of an energy reserve), it must be possible to slow the tractor to a halt with a deceleration equal to at least 50 % of the value laid down in point 2.1.1 of Annex II.

These conditions shall be fulfilled when residual braking is achieved on wheels located on both sides of the median longitudinal plane (without the tractor deviating from its course).

For the purposes of this Section, the lever and cam assemblies, or similar assemblies, by means of which the brakes are applied, shall not be regarded as liable to failure.

4.2.3. Where use is made of energy other than the muscular energy of the driver, there need not be more than one source of such energy (such as hydraulic pump, air compressor, etc.) provided the requirements of point 4.2.2 are fulfilled.

4.2.4. The service braking device must act on both wheels of at least one axle.

4.2.5. The action of the service braking device must be distributed between the wheels of the same axle symmetrically in relation to the median longitudinal plane of the tractor.

4.2.6. The service braking device and the parking braking device must act on braking surfaces permanently connected to the wheels through components of adequate strength. It must not be possible to uncouple a braking surface from the wheels.è1 When more than one axle is normally subject to braking, one axle may be decoupled provided that activation of the service brake automatically recouples this axle and that, if the recoupling device fails, this is done automatically. ç

When one axle is subject to braking, the differential must not be mounted between the service brake and the wheels of that axle; when two axles are subject to braking, the differential may be mounted between the service brake and the wheels on one of the two axles.

4.2.7. Wear on the brakes must be easily compensated for by means of a system of manual or automatic adjustment. In addition, the control and the components of the transmission and the brakes must possess a reserve of travel such that, when the brakes become heated or when the brake linings have reached a certain degree of wear, effective braking is ensured without an immediate adjustment being necessary.

4.2.8. In hydraulic braking devices, the filling ports of the fluid reservoirs must be readily accessible; in addition, the containers of reserve fluid must be so made that the level of the reserve fluid can be easily checked without the containers having to be opened.

4.2.9. Every tractor fitted with a brake activated from an energy reservoir must, where the prescribed braking performance is impossible without the use of stored energy, be fitted with a warning device, in addition to the pressure gauge, giving a signal which can be seen or heard when the energy, in any part of the installation up to the control valve, falls to 65 % or less of its normal value. That device must be directly and permanently connected to the circuit.

4.2.10. Without prejudice to the requirements of point 4.1.2.1, where the use of an auxiliary energy source is essential for the operation of a braking device, the energy reserve must be such as to ensure that, should the engine stop, the braking performance remains sufficient to bring the tractor to a halt under the prescribed conditions.

4.2.11. Any auxiliary equipment shall draw its energy only in such a way that its operation, even in the event of damage to the energy source, cannot cause the reserves of energy feeding the braking devices to fall below the level indicated in point 4.2.9.

ANNEX III

SPRING BRAKES

1. DEFINITION

‘Spring brakes’ are braking devices for which the energy required for braking is supplied by one or more springs acting as an energy accumulator.

2. SPECIAL REQUIREMENTS

2.1. A spring brake must not be used as a service brake.

2.2. A small variation in any of the pressure limits which may occur in the brake compression chamber feed circuit must not cause a significant variation in the braking force.

2.3. The feed circuit to the spring compression chamber must include an energy reserve which does not supply any other device or equipment. This requirement shall not apply if the springs can be maintained in the compressed state by using two or more independent systems.

2.4. The device must be so designed that it is possible to apply and release the brakes at least three times starting with an initial pressure in the spring compression chamber equal to the maximum design pressure. This requirement must be met when the brakes are adjusted as closely as possible.

2.5. The pressure in the compression chamber below which the springs begin to actuate the brakes, with the latter adjusted as closely as possible, must not be greater than 80 % of the minimum level of the normal available pressure.

2.6. When the pressure in the spring compression chamber falls to the level at which the brake parts begin to move, a warning signal which can be seen or heard must be activated. Provided this requirement is met, the warning device may be that specified in point 4.2.9 of Annex I.

2.7. On tractors fitted with spring brakes and authorized to draw trailers with continuous or semi-continuous brakes, automatic application of the spring brakes must cause the trailer brakes to be applied.

3. RELEASE SYSTEM

3.1. Spring brakes must be so designed that, in the event of failure, it is possible to release them without using their normal control. This may be achieved by the use of an auxiliary device (pneumatic, mechanical, etc.).

3.2. If the operation of the auxiliary device referred to in point 3.1 requires the use of a tool or spanner, the tool or spanner must be kept on the tractor.

ANNEX IV

PARKING BRAKING BY MECHANICAL LOCKING OF THE BRAKE CYLINDERS (LOCK ACTUATORS)

1. DEFINITION

‘Mechanical locking of the brake cylinders’ means a device for ensuring the operation of the parking brake by mechanical wedging of the brake piston rod.

Mechanical locking occurs when the locking chamber is emptied of compressed air; the mechanical locking device shall be designed in such a way that it can be released when the locking chamber is again subjected to pressure.

2. SPECIAL REQUIREMENTS

2.1. When the pressure in the locking chamber approaches the level corresponding to mechanical locking, an optical or acoustic warning system must be activated.

2.2. In the case of brake actuators fitted with a mechanical locking device, the brake actuator must be capable of being actuated by either of two energy reserves.

2.3. The locked brake cylinder may only be released if it is certain that the brake can be operated again after such release.

2.4. In the event of a failure of the source of energy supplying the locking chamber, an auxiliary unlocking device (mechanical or pneumatic, for instance) using, for example, the air in one of the tyres of the tractor, must be provided.
