Wet multi-disc brake device for heavy equipment

摘要

The present invention relates to a wet type multi-disc brake apparatus for heavy equipment, comprising an inner guide portion (8) directly splined to an axle shaft (1) in a brake adapter (2) driven by a power transmitted from an engine A spiral oil guide passage 11 is formed in the outer side inner peripheral face 10 along the radial direction of the oil supply groove 9 and the oil guide passage 11 A plurality of oil holes 12 are drilled in the circumferential direction of the brake adapter 2 so that the oil in the oil supply groove 9 due to the centrifugal force generated as the brake adapter 2 rotates together with the axle shaft 1, The oil for lubricating and cooling the brake plate and the brake friction plate is supplied through the oil hole 12 to the space between the brake plate 4 and the brake friction plate 3, And is supplied to the inner brake device through the passage 11 and the oil hole 12 so that a sufficient amount of oil is supplied.
