<p>Vehicle 10 has a rear suspension 18 pivotable from a trailing arm position (Fig. 1) to a leading arm position (Fig. 2) to alter the vehicle wheelbase. This may allow carriage of additional seats or luggage space (not shown). Suspension arm 24 and bush 26 may rotate about a fixed bracket (28, Fig. 3). A bell crank (34, Fig. 3) may pivot around the bracket to actuate a spring and damper assembly (40, Fig. 3), which compresses in bound and extends in rebound in both vehicle modes. A switchable spring lock (48, Fig. 3) may allow arm 24 to pivot fore and aft without over-extending the spring and damper. Torsion bars (123, Fig. 8) may be used as suspension springs. Suspension pivoting may be driven by a wheel motor (not shown); or pneumatically, hydraulically, or by a chassis mounted motor (134, Fig. 9).</p> |
