Title:
SIDE FORCE DETECTION OF SNOWPLOW, DRAG GENERATOR, AND CONTACT FORCE HOLDING DEVICE FOR CASTER WHEEL
Document Type and Number:
Japanese Patent JP3658345
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve problems such that a large load is placed on a driver, driver's fatigue is increased, and a high degree of skill is required, etc., since a side slip is conventionally prevented by directing front wheels in the direction in which drag force is generated against side force by handle operation by the driver against the side force generated by a snowplow at the time of snowplowing in the snowplow provided to a front part of a snowplow vehicle.
SOLUTION: Generation of the drag force against the side force generated by the snowplow is constituted in such a manner that pressure generated at a folding cylinder and at an angling cylinder is detected by a pressure transducer, an electric signal in which swinging of the snowplow and a supporting frame is detected by a load transducer is inputting to an automatic control part, and caster wheels are automatically and properly leaned up to an angle θ by telescopic operation of a leaning cylinder in the direction that the drag is generated via a proportional control solenoid valve based on a command signal after arithmetic processing.
