SUSPENSION SYSTEM - Rear Suspension
SM - 3071
DESCRIPTION
Numbers in parentheses refer to Fig. 1.
Each axle is coupled to the chassis by three rubber
bushed leading or trailing control links (5) which
provide longitudinal restraint. Lateral restraint is by
transverse control links (31).
Loads acting on the centre and rear axles are balanced by
centrally pivoting equalizer beams (4) with rubber cushioning
interleaf mounts (7) between axles and beam ends.
Interleaf mounts (7) are rubber/steel laminated
compression units with chain link ties.
The rear suspension system is effectively
maintenance free due to the use of rubber bushings (6
& 32) being used in control links (5 & 31). Lubrication
