WET TYPE MULTI-DISK BRAKE FOR HEAVY EQUIPMENT

摘要

The wet multiple laminated disc brake has a plurality of brake friction plates(3) formed on a brake adapter(2) rotated with an axle shaft to be moved along the length direction of the brake adapter(2), and a plurality of brake plates(4) inserted between the brake friction plates(3) and connected to a piston(7) coupled to an axle housing(5) or a brake housing(6). The braking operation is implemented by means of friction force generated between the brake plates(4) and the brake friction plates(3). The brake includes: an inside guide(8) and an oil supply groove(9) directly spline-coupled to the axle shaft(1); a spiral oil induction path(11) formed on the outer side of the interior of the radial direction of the oil supply groove(9); and a plurality of oil holes(12) formed along the circumference direction in the oil induction path(11), whereby the oil existing in the oil supply groove(9) is supplied between the brake plates(4) and the brake friction plates(3) through the oil holes(12) by the centrifugal force generated due to the rotation of the axle shaft(1) with the brake adapter(2).
