Title:
摺動式トリポード形等速ジョイント
Document Type and Number:
Japanese Patent JP5109515
Kind Code:
B2
Abstract:
A sliding-type tripod-shaped constant-velocity universal joint is provided, sliding-type tripod-shaped constant-velocity universal joint which is capable of being downsized while reducing induced thrust force. A constant-velocity universal joint 1 is equipped with: an outer race 10; a tripod 20 that is equipped with a boss portion 21 and three tripod-shaft portions 22 being inserted into roller grooves 11; and rollers 30. And, a shaft-axis-wise width "bx" of the tripod-shaft portions 22 is formed smaller as it goes from the root side to the leading-end side in a torque transmission region of the tripod-shaft portions 22. Further, a torque-transmission-wise width "ax" of the tripod-shaft portions 22 is formed greater as it goes from the root side to the leading-end side in the torque transmission region when defining a direction that intersects with the shaft axis and the tripod-shaft portions 22 orthogonally as a torque transmission direction.
