Control structure of a shifting fork

Abstract

The invention provides a control structure of a shifting fork. The control structure of the shifting fork is capable of ensuring the selecting and shifting accuracy of the whole structure, and is small in radial range and facilitates the reasonable arrangement of a gearbox. The control structure of the shifting fork comprises a shifting fork shaft, an interlocking device and a plurality of shifting forks, wherein the input connecting parts of the plurality of shifting forks correspondingly sleeve the shifting fork shaft; shifting fork slot plates which are arranged along the axial length are correspondingly mounted at the input connecting parts of the shifting forks; the shifting fork slot plates are arranged at different radial positions on the shifting fork shaft; each shifting fork slotplate is provided with a shifting fork concave slot at a position corresponding to the axial length of the shifting fork shaft; the interlocking sleeve sleeves a corresponding area in the shifting fork concave slots; the interlocking device comprises an annular boss which is used for locking the corresponding shifting fork slot plate by clamping the shifting fork groove; and the interlocking device further comprises an opening slot which is formed in the surface, and a guide sunken groove which is formed in the inner wall of the through hole.

Description

technical field [0001] The invention relates to the technical field of automobile transmission, in particular to a control structure for a shift fork. Background technique [0002] In the existing transmission manipulation technology, the shift fork shafts and shift forks are arranged in one-to-one correspondence, which makes the number of shift fork shafts larger and the space required by the transmission is larger; when one shift fork shaft corresponds to multiple shift forks After the technology of the shift fork, an interlock mechanism needs to be provided. However, the combination of the existing interlock mechanism and the shift fork shaft occupies a large radial area, and the selection and shifting accuracy is not high. Contents of the invention [0003] In view of the above problems, the present invention provides a control structure of a shift fork, which can ensure the accuracy of the entire structure in selecting and shifting, and has a small radial range, which...
