PARTIAL BRAKE SYSTEM OF RIDING TYPE TRACTOR

摘要

PURPOSE: A partial brake system of a riding type tractor is provided to reduce the turning radius of a riding type tractor by installing a partial brake to the riding type tractor in addition and to make a partial brake of the inner wheel automatically operated without working the pedal when turning. CONSTITUTION: In a riding type tractor(50), a side of a connecting rod(66) is coupled to a drive case(64) of a front wheel tire(56) and the other side is coupled to an arm combination(70) with connected with a ball joint(68). The arm combination is fixed to an axle bracket(52) through a fixed shaft(72) and rotates by the connecting rod. Plates(74) are formed to both side of the axle bracket. A side of a tension spring(76) is connected to the plate and the other side is connected with cables(78). The cable is positioned near brake arm combinations(80). Automatic brake arm combinations(82) are installed to the side of the brake arm combination. The brake arm combination is connected to the automatic brake arm combination and partial insertion plates(86) are formed to a side the automatic brake arm combination. Brake rods(88) are coupled to the structure formed to a side of the partial insertion plate. Pin combinations(84) are coupled to the brake arm combination longitudinally and the pin combination operates a partial brake. Therefore, the turning of the riding type tractor is softly performed and the operation is simple.
