Stepless adjustable shifting fork structure

Abstract

The invention provides a shifting fork structure capable of being steplessly adjusted and connected. The shifting fork structure comprises a shifting fork shaft, a shifting fork head, a shifting fork foot and a shifting fork, wherein the shifting fork head and the shifting fork foot are arranged at the two ends of the shifting fork shaft respectively; two wedge openings are formed in the side face of the shifting fork shaft, two inclined locking screws are arranged on the shifting fork in an inverted splayed mode, and the ends of the two locking screws abut against the interiors of the two wedge openings respectively. The included angle of the inner end of the wedge opening is 90 degrees or larger than 90 degrees or smaller than 90 degrees. According to the shifting fork structure capable of being steplessly adjusted and connected, through the shifting fork capable of being steplessly adjusted and connected and the shifting fork shaft device, the shifting fork can be adjusted in place at a time according to the positions of the shifting fork and the synchronizer, the shifting fork is stressed in different directions according to the principle, and the anti-loosening and locking effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of shifting forks, and in particular relates to a shifting fork structure that can be adjusted steplessly. Background technique [0002] The mechanical shifting form in the transmission system of the tractor is generally realized by controlling the front and rear linear motion of the synchronizer by the shift fork. The requirements for the position degree are relatively high, and the situation that the shift fork and the synchronizer are not aligned often occurs, which will cause failures such as inability to shift gears, abnormal noise, and burning of the synchronizer. At present, the usual solution is to use the form of grading and selecting the fork shafts, that is, to make multiple fork shafts of different sizes, select them in stages, and when assembling and adjusting, if it is found that the fork and the synchronizer are not aligned, then replace them. Different fork shafts can be adjusted until the s...
