A dynamic-setting process and device, for apparatus designed to check the dynamic behaviour of tyres.

摘要

The dynamic setting of an apparatus (1) designed to check the behaviour of tyres comprises a rotating drum (9) arranged to act in thrust relation on a tyre (5) set in rotation, as well as dynamometer cells (10) connected to an electronic processing unit (12) for detecting the dynamic forces transmitted from the tyre (5) to the drum (9). The setting is carried out by applying a predetermined static load to the drum (9) and afterwards transmitting cyclic dynamic forces having a predetermined frequency, intensity and dynamic variation to said drum. The cyclic forces are produced by an eccentric (20) transmitting a reciprocating motion to a movement block (22) connected to the dynamometer cells (10) by springs (29, 31). Signals emitted by the dynamometer cells (10) are detected and stored by the processing unit (12) in order to obtain data to be compared with signals emerging during the test of a tyre (5). <IMAGE>
