<p>A bobsled (10) provides steering control for all four of its runner assemblies (22 and 23). The left runner assemblies (22 and 23) are coupled through tie rods (55 and 56) to the right runner assemblies (22 and 23), and these assemblies (22 and 23) are coupled through a steering linkage (31, 36-42, 45, 46, and 49-54) and cables (62 and 66) to a push-pull pair of control levers (57 and 58). Operation of the levers (57 and 58) moves the linkage axially to pivot front and rear bell cranks (45 and 46) counter to one another, resulting in the rear runner assemblies (23) being pivoted counter to the front runner assemblies (22) to follow an arcuate track through a turn. The steering system extends through the front and rear axles (68 and 69) which are coupled to the frame (12) through a suspension system and which are allowed to pivot in plates transverse to longitudinal axis of the bobsled (10).</p> |
