Working vehicle

摘要

An operating system is formed in which an engagement shaft supported on an end portion of a brake piston is inserted through an engagement hole portion of a balance member; an operation wire is connected to the balance member via a coupling pin; and brake operating arms of rear wheel brake mechanisms are operated by a pair of arm portions of the balance member. A broad area is formed in the engagement hole portion in a manner allowing the balance member to swing about the coupling pin when the operation wire is pulled.

主权项

1. A working vehicle comprising:
a brake operating system transmitting a brake operating force of a brake operating device from an equalizer to brake mechanisms of left and right wheels, the equalizer having a pair of arm portions transmitting the brake operating force to the left and right brake mechanisms; and a swingable balance member absorbing a difference between operating strokes of the left and right brake mechanisms, the brake operating device comprising:
a single brake piston being actuated in a projecting direction by pressure of brake oil supplied by a depression operation of a brake pedal; anda brake operating member transmitting an operating force of a parking brake operating tool, wherein
the brake operating member is connected to and applies a pulling force from one side of the balance member,the brake piston is structured and arranged to transmit an actuating pushing force in the projecting direction to the balance member, said pushing force being exerted from an opposite side of the balance member, andmovement of the brake operating member during application of the pulling force allowing relative linear movement between the brake piston and the balance member.
