Embodiment Construction

[0015] Such as figure 1 and figure 2 Commonly shown, the gearbox housing 1 passes through several shift fork shafts 2 in parallel, and the shift fork shafts 2 are respectively provided with neutral gear ring grooves 21, and the shift ring grooves 21 are located on both sides of the neutral gear ring grooves. The upper part of the fork shaft 2 has a self-locking groove 22. Of course, only two shift fork shafts 2 are shown in the figure to explain the present invention. When the gearbox includes multiple shift fork shafts, the principle is the same; The shift fork shaft 2 can move along its axial direction so as to complete operations such as gear shifting and gear shifting, which are well-known technologies in the technical field and will not be repeated here.

[0016] On the outer wall of the gearbox housing 1, a self-locking interlocking block 3 is fixed by a bolt 6, and the self-locking interlocking block 3 is provided with a shift fork shaft hole corresponding to the shif...

Abstract

The invention discloses a self-locking and interlocking mechanism for shifting fork shafts of a gearbox, which comprises a plurality of parallel shifting fork shafts penetrating through a gearbox shell. Corresponding neutral annular grooves are arranged on the shifting fork shafts respectively, two sides of each neutral annular groove are positioned on the upper portion of the corresponding shifting fork shaft and provided with self-locking grooves, a self-locking and interlocking block is arranged on the outer side wall of the gearbox shell and provided with a plurality of shifting fork shaft holes, a self-locking device and an interlocking device, the shifting fork shafts penetrate through the shifting fork shaft holes, the self-locking device is matched with the self-locking grooves, and the interlocking device is matched with the neutral annular grooves. Self-locking and interlocking devices originally mounted inside the gearbox shell are mounted outside the gearbox shell, complicated self-locking and interlocking holes machined on the gearbox shell are avoided, machining complexity and rejection rate are reduced, and tightness of the gearbox shell is also improved.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a self-locking and interlocking mechanism of a shift fork shaft of a gearbox. Background technique [0002] The principle of self-locking and interlocking of the existing gearbox shift fork shaft is roughly the same. The self-locking principle is to process a deep hole on the inner wall of the gearbox housing on the upper part of the shift fork shaft, and a self-locking spring and a self-locking spring are arranged in the deep hole. Lock the steel ball, and process three grooves on the side of each shift fork shaft facing the steel ball. The middle groove is a neutral groove, and the grooves on both sides are self-locking grooves. The self-locking steel ball is The self-locking spring is pressed into the corresponding groove of the shift fork shaft to lock the gear and prevent automatic shifting and automatic disengagement. When shifting is required, the axial force exerted by ...
