ROLLING TESTBED FOR TYRES OR RIMS WITH EXTENSION MEASURING ELEMENTS ON DEFORMABLE FLEXING BARS

摘要

A rolling testbed for tyres or rims comprises a mounting spindle (8) for a vehicle wheel (5), the spindle bearing (9) of which is mounted on a carriage (12) which may be displaced radially in relation to a running drum (3). A force measuring device has a measuring body (10), between the spindle bearing (9) and the carriage (12), which has, by way of deforming bodies, at least one flexing bar (19), deformed only by radial forces and at least one flexing bar (16), deformed only by axial forces. Flexing bars (16, 19) have extension measuring elements (21, 22), which are connected to an analytical circuit in the force measuring device.
