Council Directive 93/14/EEC of 5 April 1993 on the braking of two or three-wheel motor vehicles (repealed) (c. 14)

ANNEX

1. DEFINITIONS

For the purposes of this Directive:

1.1. Type of vehicle with respect to its braking:

means vehicles which do not differ in such essential respects as:

1.1.1. the vehicle category, as defined in Article 1 of this Directive;

1.1.2. the maximum mass, as defined in 1.13;

1.1.3. the distribution of mass among the axles;

1.1.4. the maximum design speed;

1.1.5. a different type of braking system;

1.1.6. number and arrangement of the axles;

1.1.7. engine type;

1.1.8. the number of gears and their overall ratio;

1.1.8a. final drive ratios;

1.1.9. the tyre dimensions.

1.2. Braking device:

means the combination of parts other than the engine whose function is progressively to reduce the speed of a moving vehicle or to bring it to a halt, or to keep it stationary if it is already halted; these functions are specified in 2.1.2. The device consists of the control, the transmission and the brake proper.

1.3. Control:

means the part actuated directly by the driver to furnish to the transmission the energy required for braking, or for controlling it. This energy may be the muscular energy of the driver, or energy of another source controlled by the driver, or a combination of these various kinds of energy.

1.4. Transmission:

means the combination of components comprised between the control and the brakes and linking them functionally. 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 is likewise part of the transmission.

1.5. Brake:

means the parts of the braking device in which the forces opposing the movement of the vehicle are developed.

1.6. Different types of braking devices:

means devices which differ in such essential respects as:

1.6.1. components having different characteristics;

1.6.2. a component made of materials having different characteristics, or a component differing in shape or size;

1.6.3. a different assembly of the components.

1.7. Component(s) of a braking device:

means one or more of the individual parts which, when assembled, constitute the braking device.

1.8. Combined braking system means:

1.8.1. in the case of two-wheel mopeds and two-wheel motorcycles, a system whereby at least two brakes on different wheels are actuated in combination by the operation of a single control;

1.8.2. in the case of three-wheel mopeds and tricycles, a braking device which operates on all the wheels;

1.8.3. in the case of motorcycles with sidecar, a braking device which operates at least on the front and on the rear wheel. Therefore a braking device which operates simultaneously on the rear wheel and on the sidecar wheel is regarded as a rear brake.

1.9. Progressive and graduated braking:

means braking during which, within the normal operating range of the device, and whether during the application or during release of the brakes:

1.9.1. the driver can at any moment increase or decrease the braking force by acting on the control;

1.9.2. the braking force varies proportionally to the action on the control (monotonic function); and

1.9.3. the braking force can be easily regulated with sufficient precision.

1.10. Maximum design speed:

means the speed which the vehicle cannot exceed, on the level and without undue external influence, taking into account any special limitations imposed on the design and construction of the vehicle.

1.11. Laden vehicle:

means, except where otherwise stated, a vehicle so laden as to attain its maximum mass.

1.12. Unladen vehicle:

means the vehicle alone, as submitted for the tests, plus the driver alone and any necessary test equipment or instrumentation.

1.13. Maximum mass:

means the maximum mass stated by the vehicle manufacturer to be technically permissible (this mass may be greater than the permissible maximum mass laid down by the national administration).

1.14. Wet brake:

means a brake or brakes which has/have been treated in accordance with Section 1.3 of Appendix 1.
