Radial Axial fatigue test machine


The machine allows the simulation of an endurance fatigue test on car wheels subjecting them to radial and axial fatigue stress and holding the test conditions in time.

In the machine station it is possible to stress a rim with radial and axial loads at the same time.

The testing machine perfectly complies with Standards SAE J328/1204, ISO 3894, FIAT 7-B8000.

It is composed of a soldered steel base on which one station or two stations can be mounted. The wheel is enabled to move along the longest axis of the base as well as to spin around this axis, generating on the rim the effect of a continuous steering during the running (axial fatigue).

The longitudinal motion (radial) pushes the wheel against a driving roller 1730 mm diameter, motioned by a high efficiency toothed belt by a 100 kW direct current motor.

This motor allows a speed range between 0 and 300 tr/min, corresponding to the roller’s peripheral speed of 100 Km/h, which is enough to fulfil the requirements of the most important automobile Companies.

The whole machine is protected by anti-intrusion panels, moving on sliding guides. Safety limit-switches, which stop the machine in case of grids violation, are present on them.


Ø The machine is fitted, in its upper part, with a lifting hoist that is able to serve both the stations, in order to allow the operator to easily fix/remove the wheel on the machine
