Abstract

The invention relates to a multiaxial self-locking interlocking device which comprises a self-locking interlocking block, a first shifting fork shaft, a second shifting fork shaft and a third shifting fork shaft, wherein the first shifting fork shaft and the third shifting fork shaft are symmetrically arranged on both sides of the second shifting fork shaft, No.1 neutral grooves are respectively formed in one side, which faces towards the second shifting fork shaft, of the outer circumferential surfaces of the first shifting fork shaft and the third shifting fork shaft, No.2 neutral grooves are respectively formed in both sides of the outer circumferential surface of the second shifting fork shaft, a first shifting fork hole, a second shifting fork hole and a third shifting fork hole which are respectively matched with the three shifting fork shafts are longitudinally formed in the self-locking interlocking block in sequence, through holes which are mutually perpendicular to the three shifting fork holes are horizontally formed in the self-locking interlocking block, No.1 through holes which are mutually perpendicular to the No.1 neutral grooves are horizontally formed respectively in the first shifting fork shaft and the third shifting fork shaft, and a No.2 through hole which is mutually perpendicular to the No.2 neutral grooves is horizontally formed in the second shifting fork shaft. The multiaxial self-locking interlocking device has the advantages of simple structure, wide application range, convenience in processing and simplicity in assembly.

Description

technical field [0001] The invention relates to the technical field of vehicle gearboxes, in particular to a multi-axis self-locking and interlocking device, which is mainly suitable for improving the integration of the self-locking and interlocking device mechanism, thereby effectively reducing processing difficulty and simplifying installation. Background technique [0002] In order to ensure the smooth operation of the gearbox and avoid gear disengagement, it is necessary to design a corresponding gear self-locking device for the gearbox. At the same time, in order to avoid simultaneous engagement of two gears in the same shift control system, it is necessary to design a corresponding interlock device. [0003] The Chinese patent authorization announcement number is CN203627771U, and the utility model whose authorization announcement date is June 4, 2014 discloses a self-interlocking device for a shift mechanism of an automobile transmission, which consists of a shift for...
