Title:
HYDRAULIC MOTOR
Document Type and Number:
Japanese Patent JP3911211
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hydraulic motor capable of certainly eliminating the friction resistance of a brake disc when the brake is disengaged.
SOLUTION: The hydraulic motor 1 is composed of a plurality of pistons 6 reciprocating with liquid pressure, a cylinder block 3 rotating through the pistons 6, an output shaft 2 to output the rotation of the cylinder block 3, the brake disc 21 rotating together with the cylinder block 3, a brake driving mechanism 25 to give a friction force to the brake disc 21, and cases 11 and 12 to accommodate the cylinder block 3, the brake disc 21, and the brake driving mechanism 25, wherein the cases 11 and 12 are provided with a communication passage 30 to put the two chambers 14 and 15 partitioned by the brake disc 21 in mutual communication.
