Claims

[Claims for Utility Model Registration] 1. A friction element group consisting of one and the other friction elements 3 and 4 supported by the brake shaft 1 and the brake housing 2 so as to be slidable only is provided on the brake housing 2 side. In a work vehicle equipped with a friction multi-disc brake 6 that brakes the braked shaft 1 by obtaining frictional engagement between the friction elements 3 and 4 pressed against the pressure receiving surface 5, the brake housing 2 has the above-mentioned One end side and the other end side of the friction element group define one and other annular lubricating oil supply passages 7 and 8, and the oil in the braked shaft 1 is provided at a position outward from one end surface of the braked shaft 1. A lubricating oil supply space 11 is defined which communicates with the inner circumferential end position of the friction element group through passages 9 and 10, and the lubricating oil supply space 1 is connected to one of these and other lubricating oil supply passages 7 and 8.
A lubrication device for a friction multi-disc brake, in which lubricating oil supply oil passages 12 and 13 bored in a brake housing are communicated with 1 and 1. 2 A lubricating device for a friction multi-disc brake as set forth in claim 1 of the Utility Model Registration Claim, in which a braked shaft 1 of the above-mentioned one and other lubricating oil supply passages 7 and 8 is provided.
A lubricating device in which a lubricating oil supply passage 13 located on the one end surface side of the lubricating oil supply space 11 and the lubricating oil supply space 11 are made to communicate with each other inside the brake housing 2.
