Title:
VEHICLE SUBFRAME MOUNTING
Document Type and Number:
WIPO Patent Application WO2003037699
Kind Code:
A3
Abstract:
A subframe (44) for a vehicle with an improved mounting arrangement is provided. The subframe (44) includes a first member (90) extending transverse to the longitudinal frame rails (14, 16) on a vehicle frame (10) and is mounted to the frame at a first mounting point (138) between the frame rails (14, 16). The subframe (44) further includes second and third members (92, 94)that extend from either side of the first member (90) to support suspension control arms (29, 30, 32, 34), spring/shock units (36, 38), and a steering linkage (42). The second and third members (92, 94) are coupled to the frame rails (14, 16) at second and third mounting points (140, 142). The three mounting points form a generally triangular mounting arrangement that enables greater deflection of the frame rails (14, 16). Rubber isolators (46, 48, 50, 52) may be used at the mounting points to further increase frame rail deflection and reduce vibration. Further, the second and third members (92, 94) form spring seats (92, 94) for the spring/shock (36, 38) units at locations outboard of the frame rails (14, 16) thereby moving spring reaction points outboard of the vehicle frame (10).
