FOREWORD
This technical catalogue is the summary of the efforts that A.D.R.
Group, thanks to the experience of its customers, has made in
research and development of axles and brakes for a wide range of
haulage vehicles.
Although we have tried to make as comprehensive as possible
some of the information could be incomplete or inaccurate: we apologize
for any unintentional incorrect information.
A.D.R. Group isn't responsible of incidental inaccuracies and
reserves the right to make changes without notice, if aimed at the
implementation of new laws or at the improvement of its products.
Before choosing a product, the user of this manual, should consider
all the working conditions of his vehicle and check that the A.D.R.
product he has chosen meets all those requirements.
This catalogue cannot be used as a reference document in case of
technical quarrels and in any legal action.
A.D.R. reserves copy rights for this catalogue and will prosecute
any unauthorised photocopying of either part or the whole of the catalogue.
CONTENTS
All standard A.D.R. products are printed in this catalogue with their
main characteristics:
· Axles with or without brakes
· Stub Axles with or without brakes
· Self Steering Axles
· Overrun hitches
· Multileaf and parabolic spring suspensions.
For the equipment of road trailers or agricultural machines.
USERS' GUIDE
How to choose the right axle.
The carrying capacity you'll find in the following sheets are the
maximum allowed for the corresponding speed and according to the
vehicle shown on top of the columns (single axle, many axles, tandem)
fitted with single wheels, no offset. For twin wheels or offset
discs please apply to our Technical Department. It can also help you
if the products have to be used in particular environmental conditions.
The user, after having chosen the product and the speed fit for its
purpose, must check if the axle beam (square, round or hollow section)
is suitable to the distance between the track and the fixing points
to the frame of the vehicle. Please refer to the diagrams you'll find at
the beginning of this catalogue (please remember that the track is
always referred to the wheels' centre).
Size and characteristics of tyres are very important regarding the
performances of the axle. A significant property is the static loaded
radius of the tyre: the diagrams and the lists printed in this catalogue
are valid to a maximum s.l.r. of 600 mm. Should you need to use bigger
tyre, please apply to our Technical Department.
For low pressure tyres always contact our Technical Department:
the shape of these tyres emphasizes the stress and strain conditions.
The wheel radius you'll find on the lists of the homologated brake
performances have no relation with the afore mentioned recommendations.
When tandem, tridem or similar arrangements are used, a self
steering axle is recommended, in order to reduce the stress to hubs
and wheels especially in short radius curves.
Tankers cause additional stress on axles. In this case we suggest
you refer to the catalogue, for an axle capacity increased by 10% at
least.
Pneumatic suspensions, though very efficient in shock adsorbing,
nevertheless cause extra stress on the structures, coming from the
wide elongations of air springs: thereforer we suggest you ask our
Technical Department to assist in the development of your projects.
Brake performances
The braking axles manufactured by A.D.R. agree with the requirements
of the European Norms and the National rules of the most
Countries.
Performances and homologation data of the brakes are listed on
the first pages of this catalogue. In detail:
· Homologation according to 98/12 CE European directive
· TUV homologation according to the German traffic rules
· CEMAGREF homologation according to the French law.
Together with the afore mentioned data we also list the minimum
and maximum allowed static loaded radius of tyres.
The maximum braking capacity is referred to the minimum radius:
the capacity at maximum radius should be proportionally calculated.
If the brakes have to be used with tyre whose size is not included
in the mentioned range, please apply to our Technical Department.
The radius 600 mm (ref. Size and characteristics of tyres) is not
related to the brake performance and must not affect the choice of the
braking equipment.
The next ECE Directives on traffic and safety, will extend the ABS
and the automatic slack adjusters to the brake of all the heavy vehicle:
the A.D.R. range of brakes, homologated according to 98/12 CE,
already meet these rules.
ENVIRONMENT
The analysis of the impact our products have upon the environment
is a task A.D.R. has applied itself to for a long time. Our experience
lasts from the half of the 80's: 15 years before European impositions,
A.D.R. homologated and produced asbestos free brakes.Nowadays
our target is the "zero impact" axle.
All our range has been re-designed, paying special attention to the
lubrication system; new technical solutions reduce the risks of pollution
and cut the maintenance time, to improve the service to the customers.
RESEARCH
Every A.D.R. product is the result of the knowledge and experience
gained by our Centre for Research and Development, with its hightech
equipment for structural analysis, design and testing.
Our Test Laboratory, with its equipment, unique in Europe, can simulate
the heaviest working conditions on all the components of the
braking axles.
The maximum reliability is reached through "on the road" tests with
specially equipped vehicles.
QUALITY
A.D.R. was certified ISO 9001:2000 many years ago, among the
earliest in Europe.
