Abstract

The invention discloses a shift selection and changing operation mechanism for a heavy-duty gearbox. The invention has the technical scheme that: the shift selection and changing operation mechanism, in which a self-locking mechanism, an interlocking mechanism, a reverse gear lock mechanism and a locking mechanism are integrated on a small cover shell assembly, for the heavy-duty gearbox can perform mechanical shift selection and shift changing, and can control the switching of a shift 2 secondary box so as to operate a shift 12 gearbox. The mechanism has a compact integral structure, is portable, can be post-maintained conveniently, and can effectively prevent the misoperation and increase safe reliability.

Description

technical field [0001] The invention relates to a gear selection and shifting operation mechanism of a heavy-duty gearbox, in particular to a gear selection and shifting operation mechanism of a 12-speed truck mechanical heavy-duty gearbox composed of a main box and an auxiliary box. Background technique [0002] The self-locking mechanism, interlocking mechanism, reverse gear locking mechanism and range gear locking mechanism in the selection and shifting mechanism of the 12-speed heavy-duty gearbox for trucks are generally distributed on the gearbox housing and the gearbox shifting mechanism. , although it can be realized in function, it is not convenient for assembly and maintenance, and it complicates the overall mechanism. Contents of the invention [0003] The present invention aims to overcome the above-mentioned deficiencies in the prior art, and provides a heavy-duty transmission shifting operation mechanism, which is a heavy-duty transmission integrated with a s...
