Title:
STEERING MECHANISM FOR MULTI-AXLE TRAILER
Document Type and Number:
Japanese Patent JPH0687462
Kind Code:
A
Abstract:

PURPOSE: To steer rear Wheels in the same direction easily by transmitting the transmitting force to a right and a left rear wheels sufficiently through a link mechanism in response to the rotation of a tractor without directly transmitting the link mechanism, connected in the vertical direction, to the wheels.

CONSTITUTION: In a multi-axle trailer, a king pin is projected with a fifth wheel of a tractor for travelling time from the lower surface of the front part of a load-carrying platform of the trailer through a rotating plate, and plural axles 18 are hung under a frame, which forms the lower part of the rear of the load-carrying platform, through a buffer member such as a spring. In this multiaxle trailer, a right and a left wheels 20 are fitted to both right and left sides of one axle among the plural axles through each lever 22 freely to turn, and the levers and triangle levers 23-25 are connected to each other through connecting rods 26a-26c freely to turn. The triangle levers and a rotating plate are connected by a link mechanism, which consists of plural levers and connecting rods, and since a support point of each triangle lever is adhered to the surface of the axle, the triangle levers are rotated by the transmitting force through the link mechanism in response to the rotation of a tractor, and the right and the left wheels are steered in the same direction by the rotation or the triangle levers.
