<p>A skateboard truck (200, 300), including a hanger (102", 102"') carrying an axle (104), and a baseplate (108", 108"'). The axle holds a pair of wheels, which are steered in unison by the axle. The baseplate is coupled to the hanger to permit hanger rotation about a dynamic hanger rotation axis (138"). A static mechanism (202, 302) enforces a static pivot point at a locus (111, 109') through which the dynamic hanger rotation axis passes during turning operation. Also, a dynamic mechanism (204, 402) causes the dynamic hanger rotation axis to pass through a plurality of dynamic hanger pivot points during that turning operation. Roll of the baseplate about a skateboard roll axis (152) is operable to cause a steering rotation of the axle, and also changes the action angle (150) of the truck.</p> |
