Detachable connecting units (23) connect the axle to the chassis, where each unit has a housing (27) arranged in the chassis. The housing is defined in a plane, perpendicular to the axle, by a circular peripheral edge opened in a direction parallel to the zone of the belt for permitting to engage the axle in the housing. A blocking elastic bracket (37) i.e. flat metallic rod, is connected to the axle.</p> |
