Title:
LUBRICATING STRUCTURE OF TRANSMISSION
Document Type and Number:
Japanese Patent JP2016148349
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To distribute a proper amount of a lubricant to a bearing for supporting a gear on a rotary shaft of a transmission, and a friction engaging element of a clutch uniting the gear to the rotary shaft.SOLUTION: On a canceller oil chamber partition wall 25 defining a canceller oil chamber 26 on the opposite side to a clutch oil chamber 22 across a clutch piston 21, an orifice 35 facing the inner side in diametrical directions of a plurality of friction engaging elements 20 is formed, and an orifice opening/closing member 31 moving in linkage with the clutch piston 21 is disposed in the inside of the canceller oil chamber 26. Therefore, when the clutch piston 21 is at an engagement position, the orifice 35 is opened to supply a lubricant in the canceller oil chamber 26 to the friction engaging elements 20, and when the clutch piston 21 is at an engagement releasing position, the orifice 35 is blocked to shut in the lubricant in the canceller oil chamber 26, thereby efficiently supplying a lubricant 13a from a lubrication oil path of a rotary shaft 13 to bearings 15, 16a, and 16b.SELECTED DRAWING: Figure 2
