Abstract
An undercarriage for a vehicle such as a toy truck or an adult size riding vehicle where the undercarriage allows a vertically directed tilt force to engender a turning movement of the wheels. The undercarriage is simply constructed of two spaced apart brackets having oblique slots through which an axle running between the wheels pass. The axle is also engaged by a fulcrum located midway between the brackets and two biasing tabs which are located between the fulcrum and each of the brackets. In straight ahead movement, the axle is slightly biased by the tabs to be located about the mid-point of the slots. However, when a tilt force is applied to the vehicle, then the axle will move to a lower portion of one of the slots and the upper portion of the other slot. At the same time one of the tabs is flexed so as to increase its biasing force on the axle. When the tilt force is removed, the biasing force of the tab pushes the axle to its mid-point position in the slots.
