<p>PURPOSE:To make a turning helm ratio between a front and a rear wheels variable according to a vehicle speed, by making a special character of a turning helm angle of the rear wheel to the front wheel vary by controlling an angle to be made with a groove direction of a cam plate and a moving direction of a rod variably. CONSTITUTION:Signals outputted from a front wheel turning helm angle sensor 31 detecting a turning helm angle of a front wheel 2, a vehicle speed sensor 32 detecting a vehicle speed, and a rear wheel turning helm angle sensor 33 consisting of a potentiometer detecting a helm angle of a rear wheel 8 by detecting a moving position of a second rod component 11, are inputted the controller 30 controlling the action of a turning device 7 of the helm of the rear wheel. The controller 30 possesses a function signaling a control signal controlling a turning position of a turning lever variably so as to make a special character of a turning helm angle of the rear wheel to the turning helm angle of the front wheel vary variously according to the vehicle speed as shown in a drawing by a motor 28 (actuator) of the turning device 7 of the helm of the rear wheel based on each output signal from each of sensors 31-33.</p> |
