Description

AMT electronic gear shifting manipulator for commercial vehicle

Technical Field

The utility model relates to the technical field of automobile spare and accessory parts, in particular to an AMT electronic gear shifting manipulator for a commercial vehicle with an AMT gearbox.

Background

Commercial vehicles are increasingly popularized by adopting AMT gearboxes. The gear shifting manipulators of the AMT all adopt electronic gear shifting manipulators, or are called wire-controlled gear shifting manipulators, wire-controlled gear shifters and the like. For convenience of description, the gear shifting manipulator is abbreviated as AMT hereinafter.

Due to the requirements of a gearbox and a use scene of a commercial vehicle, at least 6 gears such as a forward gear A/D, a reverse gear R, a neutral gear N, a manual gear M, a creep mode gear Dm and Rm and the like can be generally set. The conventional AMT gear shifting manipulator generally adopts a straight row and is also arranged in multiple rows, and the gear shifting control modes of corresponding gears are respectively like a straight row AMT gear shifting manipulator and a multiple row AMT gear shifting manipulator.

The gear setting of these types of AMT gear shifting manipulators is realized by adding a knob and a key gear in addition to 6 gears in a straight line and a single row or multiple rows of gears. Especially, the gears Dm and Rm of the creep mode of the commercial vehicle are used frequently, and the gear setting is good or bad, so that the driving comfort is greatly influenced.

Although the pure straight-row AMT gear shifting manipulator is simple to operate, the straight-row gears are more, gear selection is difficult, wrong gears are easy to be engaged, and meanwhile, the front gear shifting angle and the rear gear shifting angle are naturally larger due to more gears, so that the operation comfort is poor.

The multi-gear is assisted by a key or a knob gear shifting operation mode, so that the probability of gear mismatching can be reduced, but the right hand of a driver needs to be separated from a gear handle during gear shifting, and the operation comfort is not good. Meanwhile, due to the arrangement of a knob or a key, the structure of the whole gear shifting controller is complex, and the cost is increased.

In view of the above, there is a need for an improved or innovative construction for an existing shift actuator.
