Abstract
A steering assembly particularly adapted for incorporation into a remote controlled toy car is disclosed. The steering assembly includes a pair of kingpins which fixedly mount two steered wheels of the toy car. The kingpins are pivotably mounted on axles attached to a chassis of the toy car. The kingpins are also moveable on their respective axles in a substantially vertical direction relative to the chassis of the toy car. A mechanism is provided to simultaneously pivot both kingpins about their respective axles in a proportional response to a steering input by a player so that the steered wheels of the cars are turned to a desired extent. Each kingpin is in an operative camming relationship with at least one member fixedly attached to the chassis of the toy car so that the kingpin located on the inside of a turn is caused to move downward and the other kingpin located on the outside of the turn is caused to move upward. The respective up and down motions of the kingpins which carry the wheels cause a decrease in a frictional engagement of the outside wheel with the support surface and thereby cause directional instability of the toy car in the turn.
