Automated axle steering control system

摘要

The invention disclosed herein is a new steering control mechanism attached to a truck frame extension which permits trucks towing goose neck trailers to have more maneuverability while towing the trailer. Specifically, a steering control plate rests between two metal stops located on a tie rod connecting the two wheels of the truck frame extension. When the operator of the truck signals a turn the steering control plate is lifted off of the tie rod to a level above the metal stops which permits the tie rod to move in connection with the movement of the towing truck. After the truck completes the turn the steering control plate returns to rest on the tie rod between the two metal blocks locking the tie rod in place. This arrangement permits the trailer to faithfully follow the truck in straight line traffic. The invention disclosed herein permits the goose neck trailer to make sharper turns without putting stress on the tires and frame of the truck or trailer.

主权项

1. A truck frame extension designed to connect a goose neck trailer to a towing vehicle comprising:
a frame substantially rectangular in shape; an axle connected in a perpendicular orientation to the long axis of said frame; a wheel connected at each end of said axle; a tie rod pivotably attached and extending between two said wheels; a first hitch mechanism connecting said frame to said towing vehicle; a second hitch mechanism connecting said gooseneck trailer to said truck frame extension; an axle steering mechanism connected to said axle, said tie rod and said frame comprising: an actuator control mechanism, an actuator connected electrically to the said actuator control mechanism; a piston connected to said actuator; a steering control plate attached to said piston; a plurality of downward biasing springs attached by threadable fasteners to the upper side of said steering control plate; a plurality of upward biasing springs attached by threadable fasteners to the underside of said steering control plate; a tie rod with two metal stop blocks positioned to permit said steering control plate to rest on said tie rod between said metal stop blocks; whereby when said actuator compresses said piston, said steering control plate is raised above the level of said metal stops permitting the tie rod to pivot in accordance with said towing vehicle's momentum allowing said tires on said truck frame extension to pivot in a direction opposite the direction of turn of said towing vehicle.
