Abstract
In one embodiment of the invention, a steering system for mobile medical equipment is disclosed including left and right steerable wheel assemblies including left and right steerable wheels, left and right parallelogram linkages coupled to the left and right steerable wheel assemblies, a steering function generator coupled to the left and right parallelogram linkages, and a steering tiller coupled to the steering function generator. The left and right parallelogram linkages transfer differing left and right wheel angles to the left and right steerable wheel assemblies respectively. The steering function generator generates the left wheel angle (LWA) of the left steerable wheel and the right wheel angle (RWA) of the right steerable wheel. The steering tiller receives an input steering angle to generate the left wheel angle and the right wheel angle to control the direction of the mobile medical equipment around flooring.
