15. ABSTRACT RESILIENT MOUNTING A resilient mounting comprising a tubular bush (3) of elastomeric material acting between and bonded to confronting surfaces (10,12) of rigid inner and outer members (1,2). The bush (3) is formed with a cut-out (13) on that side which would otherwise be subjected to tensile forces and the relative spacing between the members is subsequently reduced to close at least part of the cut out (13) and selectively pre-load the elastomeric material in the unloaded condition. The relative movement necessary to close the cut-out under rebound conditions is thereby reduced providing an improvement in ride characteristics when using the mounting. The reduction in spacing can be controlled to give the required pre-loading and may be sufficient to ensure that the elastomeric material is always under compression thereby avoiding the occurrence of tensile forces with consequent improved fatigue life. Preferably the mounting incorporates resilient limit stops (15,16) to control relative movement between the members (1,2) both in the axial direction of the bush (3) and vertically under a working load.
