DETECTOR FOR AXLE SWING ANGLE OF INDUSTRIAL VEHICLE, AND INDUSTRIAL VEHICLE

摘要

PROBLEM TO BE SOLVED: To accurately detect the swing angle of an axle for supporting a traveling shaft in an industrial vehicle. SOLUTION: A rear axle 10 for supporting the rear wheel 11 of a forklift is supported on a car body frame 1a so as to be rocked up and down around a center pin 10a. A potentiometer 26 is attached to a cover 31 supported on the car body frame 1a by a bracket 29. The input shaft 26a of the potentiometer 26 is connected to a bracket 35 fixed on the upper surface of the rear axle 10 by a linking mechanism 27. The linking mechanism 27 is provided with a first link 37 whose one end is connected to the bracket 35 and a second link 38 whose one end is connected to the input shaft 26a. A ratio between a distance from the center O of a center pin 10a to the first link 37 and the length of the am of the second link 38 is set to A/B≈4. The rotational angle of the input shaft 26a is enlarged by A/B (about four times) of the displacing angle of the rear axle 10.
