Description
Technical field
This utility model relates to automobile gearbox AMT and controls technical field, is specifically related to a kind of commercial car AMT gear shift mechanism.
Background technology
Shifting control is the key components and parts that AMT controls, and in order to substitute the work of conventional manual case, existing market has many
Money gear shift mechanism, but in principle, there is also a little shortcoming.Block selecting many employings roller screw of existing electric motor type gear shift mechanism or
Gear reduction unit, but owing to these mechanisms do not have self-locking performance, so shifting axle is in action of gravity when drive range is in neutral
Under have the phenomenon fallen down.This utility model uses turbine and worm to carry out block selecting control, utilizes the self-locking performance of mechanism, it is ensured that
Block selecting position reliable.The gearshift of existing electric motor type gear shift mechanism uses roller screw more, after working long hours, with
The abrasion of gear maintaining body, owing to gearshift does not has auto-lock function, then there will be and cannot keep after gear, cause de-
The phenomenon of gear, reduces power interruption to shorten AMT shift time, needs to carry out into gear action while block selecting, but existing
If some gear shift mechanisms to realize this function, due to shifting shaft block selecting and enter gear interlocking capability, if control improper, with
The fatigue of parts, easily cause shifting shaft to be twisted off.
Utility model content
The purpose of this utility model is primarily to solve above-mentioned technical problem, and provides a kind of commercial car AMT gear shift mechanism.
This utility model includes that gear box and shifting shaft, described shifting shaft are provided with gear selecting annular groove, described gear shift mechanism
Including shift motor, gearshift worm screw, gearshift tooth fan, step electric machine, gear selecting worm screw, gear selecting tooth fan and gear selecting pin, described in change
Gear motor is arranged on the casing of gear box, and described gearshift worm screw is connected with the pto of shift motor, institute
Stating gearshift tooth fan to be connected with shifting shaft transmission, and gearshift tooth fan is meshed with gearshift worm screw, described step electric machine is arranged on speed change
On the casing of box body, described gear selecting worm screw is connected with the pto of step electric machine, described gear selecting tooth fan and gear selecting
Pin transmission is connected, and gear selecting tooth fan is meshed with gear selecting worm screw.

The lead angle of described gear selecting worm screw is less than 3 ° 29 ' 11 ".
Described gearshift tooth fan is connected with shifting shaft transmission by spline.
This utility model advantage is: this utility model uses turbine and worm to carry out control of shifting gears, and utilizes the self-locking performance of mechanism, protects
Having demonstrate,proved the reliable not off-gear of gearshift, shift motor drives gearshift worm screw, gearshift worm drive gearshift tooth fan to rotate, and gearshift tooth fan is logical
Cross spline and communicate rotational motion to shifting shaft.Shifting shaft due to the guiding of spline, axially moving when not with rotation
Motion interferes, and outputs annular groove on shifting shaft simultaneously, makes shifting shaft not interfere with gear selecting, so rotating when
Mechanism can be carried out in advance into gear without damaging shifting axle block selecting position is near position when.
