Traduction de «Distance between centre lines twin tyres » (Anglais → Français) :

the structure gauges, the distance between track centres, the track alignment, track gauge, maximum up and down gradients as well as the length and height of passenger platforms of the lines of the interoperable European network shall be set such as to ensure the lines' mutual compatibility and compatibility with the interoperable vehicles,

8". twinned wheels" means two wheels mounted on the same axle, the distance between the centres of their areas of contact with the ground being less than 460 mm.

It also includes any storage reservoirs for the operating medium and the return lines, but not the vehicle's engine (except for the purposes of item 4.1.3) or its drive to the energy source; 1.3.4.1. Energy source means that part of the energy supply which provides the energy in the required form e.g. hydraulic pump, air compressor; 1.3.4.2. Energy reservoir means that part of the energy supply in which the energy provided by the energy source is stored; 1.3.4.3. Storage reservoir means that part of the energy supply in which the operating medium is stored at or near to the atmospheric pressure. 1.4. Steering parameters 1.4.1. Steerin ...[+++]g control effort means the force applied to the steering control in order to steer the vehicle; 1.4.2. Steering time means the period of time from the beginning of the movement of the steering control to the moment at which the steered wheels have reached a specific steering angle; 1.4.3. Steering angle means the angle between the projection of a longitudinal axis of the vehicle and the line of intersection of the wheelplane (being the central plane of the tyre, normal to the spin axis of the wheel) and the road surface; 1.4.4. Steering forces mean all the forces operating in the steering transmission; 1.4.5 Mean steering ratio means the ratio of the angular displacement of the steering control to the mean of the swept steering angle of the steered wheels for a full lock-to-lock turn; 1.4.6. Turning circle means the circle within which are located the projections onto the ground plane of all the points of the vehicle, excluding the external mirrors and the front direction indicators, when the vehicle is driven in a circle; 1.4.7. Nominal radius of steering control means in the case of a steering wheel the shortest dimension from its centre of rotation to the outer edge of the rim. In the case of any other form of control, it means the distance between its centre of rotation and the point at which the steering effort is applied. ...

In the case of multiple axles where distance 'd' between the tyres on adjacent axles does not exceed 300 mm, the outer valances located in the space between the axles must be located at the distances set out in item 7.2.1 and must extend downwards in such a way as not to be more than 150 mm above a horizontal line passing through the centre of the wh ...[+++]eels, or in such a way that the horizontal distance between their lower extremities does not exceed 60 mm (Figure 4a).

In the case of single or multiple axles where the distance between the adjacent tyres is at least 250 mm, the outer valance must cover the surface extending from the lower to the upper part of the mudguard up to a straight line formed by the tangent to the upper edge of the tyre or tyres and lying between the vertical plane formed by the tangent to the front of the tyre and the mu ...[+++]dguard or rain flap located behind the wheel or wheels (Figure 5b).

In the case of multiple axles where the distance between the tyres on adjacent axles does not exceed 300 mm, the outer valances located in the inter-axle spaces must follow the path specified in item 9.1.3, and must extend downwards in such a way as not to be more than 100 mm above a horizontal straight line passing through the wheel ...[+++]centres (Figure 7).
