Traduction de «front wheel steer grader » (Anglais → Français) :

Auxiliary steering equipment (ASE) in which the wheels of axle(s) of vehicles of categories M and N are steered in addition to the wheels providing principal steering input not purely electric, hydraulic or pneumatic, in the same direction or in the opposite direction to the wheels providing principal steering input, and/or the steering angle of the front, centre and/or the rear wheels may be adjusted relative to vehicle behaviour. ...[+++]`; 4. item 2.1. is amended to read as follows:

Front-wheel steering equipment in which only the wheels of the front axle(s) are steered. This includes all wheels which are steered in the same direction; 1.5.3.2.

1.5.3.4. Auxiliary Steering Equipment (ASE) in which the rear wheels of vehicles of category M and N are steered in addition to the front wheels, in the same direction or in the opposite direction to the front wheels, and/or the steering angle of the front wheels and/or the rear wheels may be adjusted relative to vehicle behaviour.

Rear-wheel steering equipment in which only the wheels of the rear axle(s) are steered. This includes all wheels which are steered in the same direction; 1.5.3.3. Multi-wheel steering equipment in which the wheels of one or more of each of the front and the rear axle(s) are steered; 1.5.3.3.1. All-wheel steering equipment in which all the wheels are steered; 1.5.3.3.2. Buckle steering equipment in which the movement of chassis parts relative to each ...[+++] other is directly produced by the steering forces.

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. ...
