Title:
BRAKE SYSTEM OF INDUSTRIAL VEHICLE
Document Type and Number:
Japanese Patent JP2023107395
Kind Code:
A
Abstract:
To provide a brake system of an industrial vehicle which can achieve stable braking regardless of a battery charging rate.SOLUTION: A brake system 1 comprises: an opening control valve 18 which is arranged between a hydraulic pump 7 and a brake unit 12; a selector valve 16 which is arranged between the brake unit 12 and a master cylinder 14 and the opening control valve 18; and a brake control part 78 which controls a motor 4 for traveling to perform regenerative braking in which the motor 4 for traveling works as a generator when the charging rate of a battery 5 storing electric power supplied to the motor 4 for traveling is a threshold value or less, and which controls the opening control valve 18 so that the opening control valve 18 opens according to the control input of a brake pedal 11 when the charging rate of the battery 5 is higher than the threshold value, and which controls the selector valve 16 so that hydraulic fluid flows from the hydraulic pump 7 to the brake unit 12 to supply the brake unit 12 with brake fluid.SELECTED DRAWING: Figure 1
