ABSTRACT:
The present invention provides a steering system provided on a chassis of a toy car comprising the following elements. A rotatable steering plate is rotatably provided on the chassis so as to rotate in a horizontal plane by a predetermined maximum angle toward left and right directions from a longitudinal center axis of the chassis. A spring member is provided on the chassis and mechanically connected to the rotatable steering plate at a position spaced apart from the longitudinal center axis of the chassis for forcing the rotatable steering plate to rotate and tilt toward one of the left and right directions from the longitudinal center axis of the chassis. A steering motor is provided on the chassis for generating a rotation power and the steering motor having a motor shaft. A rotary shaft is provided on the chassis. A transmission system mechanically connects the motor shaft and the rotary shaft for transmitting the rotation power generated by the steering motor into the rotary shaft. A first wheel is so mechanically connected to a first end of the rotary shaft that the first wheel is allowed to rotate freely from the rotary shaft. A second wheel is mechanically connected to a second end of the rotary shaft. The second wheel has a clutch mechanism so operating that if the steering motor is driven, then the rotation power is transmitted to the second wheel and thus the second wheel is driven whereby the rotatable steering plate is forced to direct in parallel to the longitudinal center axis of the chassis. If, however, the steering motor is not driven, then the rotation power generated by the steering motor is not transmitted to the second wheel and thus the second wheel is not driven and does not rotate or rotates by inertia freely from the rotary shaft, whereby the rotatable steering plate is forced to rotate and tilt toward the one of the left and right directions from the longitudinal center axis of the chassis.
