Transmission shift fork

摘要

A transmission shift fork (14c, 114, 214) engages with a coupling sleeve (C1, C2, C3) of a synchronizer (S1, S2, S3) and shifting the coupling sleeve (C1, C2, C3). The transmission shift fork (14c, 114, 214) includes a first part (16), a second part (17, 117, 217) and at least one fin (21, 121, 221). The first part (16) is configured and arranged to movably mount the transmission shift fork (14c, 114, 214) in a shift fork movement direction. The second part (17, 117, 217) includes a coupling sleeve facing surface, an outwardly facing surface, and a pair of shift-direction facing surfaces (17b and 17c, 117b and 117c, 217b and 217c) disposed between the coupling sleeve facing surface and the outwardly facing surface, the coupling sleeve facing surface including at least one coupling sleeve engagement part (18, 118, 218) configured and arranged to engage with an engaging groove (M) formed on an external circumferential surface of the coupling sleeve (C1, C2, C3), the outwardly facing surface including an oil catch disposed in a position with respect to the coupling sleeve engagement part (18, 118, 218) such that the oil catch captures lubricating oil and supplies to the coupling sleeve engagement part (18, 118, 218). The fin (21, 121, 221) projects from inside an oil receiving recess (20, 120, 220) defined by the oil catch.
