| 摘要： | A trailer axle has steerable wheels that rotate on hub assemblies pivotally mounted to the axle. Connected to the axle is a mechanism for controlling the pivoting of the hub assemblies and thereby limiting the extent to which the steerable wheels turn. The mechanism has a rod disposed along the axle and pivotally connected to the hub assemblies. A bracket on the axle has an aperture through which the rod passes, the aperture permitting the rod's motion both parallel to the axle and transverse to the axle. Flanges on the rod span an opening of the aperture and slidingly engage the bracket. The flanges are translatable on the bracket transversely to the axle but are immobile in a direction parallel to the axle. The mechanism has collars at the ends of the rod and two elongate coil springs encircling the rod. One end of each spring is affixed to the collar and the other end of each spring is affixed to the flange. The springs bias the rod and hub assemblies toward a position where the hub assemblies and wheels are oriented at a desired steering angle. The position of the collars on the rod can be adjusted to vary the bias of the spring. Adjusting the collars' positions also controls the distance between the springs' coils and thereby ultimately controls the degree of steering of the wheels. |
