Description
Technical field
The technical field of automatic machinery people is the utility model is related to, specially a kind of AMT automatic gear shift apparatus.
Background technology
Electrical control automatic manual transmission case (AMT) gearshift overwhelming majority is hydraulic pressure and pneumatic at present, passes through control
Magnetic valve realizes gear selecting and gear shifting action.Its shortcoming is complicated, and cost is higher, and action process has power loss.It is existing
Some electric-controlled mechanical AMT gearshifts, it includes two parts of gear selecting and gearshift, driven by respective motor, by slowing down
Zeng Niu mechanisms, the power of motor is delivered on shifting direction.Gear shifting pulling head stirs the gearshift of speed changer C-shaped block, with gearshift
Number increases, after machine components abrasion causes drive gap to increase so that shifting positional information changes greatly, or even can exceed
The threshold value that system is pre-designed, causes program to be judged by accident, shifting disabler.And this gear shift mechanism is needed when shifting gears every time
First gear selecting is wanted to shift gears again, control difficulty is larger, and if gear selecting transmission process fails, then can not shift gears, whole mechanism also fails
.
The content of the invention
In view of the above-mentioned problems, the utility model provides a kind of AMT automatic gear shift apparatus, it eliminates gear selecting process, energy
Enough the problem of effectively avoiding gear selecting process from failing and causing gearshift failure, it monitors drive range by linear movement pick-up, instead
Feed controller, then issued an order by controller, the power that motor exports is done directly gearshift by ball-screw.
A kind of AMT automatic gear shift apparatus, it is characterised in that：It includes shift motor, selector fork, each shift motor
Output end is fixed with screw mandrel, is set with feed screw nut on the screw mandrel, the side of the feed screw nut and the selector fork
It is fixedly connected, the shift fork end of the selector fork is used for the synchro converter ring for stirring corresponding synchronizer, and every piece of gearshift is dialled
Linear movement pick-up is provided with the correspondence position of fork, the linear movement pick-up is used to monitor drive range, feed back to control
Device.
It is further characterized by：
Magnet arrangement is disposed with the selector fork, the linear movement pick-up is by the position of induced magnet so as to reality
Apply and collect drive range information；
The screw mandrel is specially ball screw；
The synchronizer is located inside gear box casing, and the other end of the screw mandrel is loaded on the speed change by bearing positioning
One side wall of device housing；
The feed screw nut be integrated in corresponding to selector fork non-bifurcation main body a side position so that feed screw nut and
The selector fork is structure as a whole, and the shift motor is installed in corresponding fixed shell by electric machine support；
The fixed shell can be the structures such as gear box casing, external rack.
After adopting the above technical scheme, shift motor, which rotates, drives screw mandrel rotation, and then feed screw nut and gearshift is driven to dial
Synchronous translation is pitched, linear movement pick-up monitors to be put into gear, and then realizes the correct execution of gear shifting action, and it passes through ball-screw
Substitute conventional gearbox shifting shaft, the power of motor output directly is completed to shift gears by ball-screw, and gearshift driving-chain significantly subtracts
It is few, gearshift more high efficient and reliable；Gearshift improves with gearbox integrated degree, makes structure compacter, cost is further
Reduce；To sum up, it eliminates gear selecting process, and the problem of can effectively avoiding gear selecting process from failing and cause gearshift failure, it is logical
Linear movement pick-up monitoring drive range is crossed, feeds back to controller, then is issued an order by controller, by the dynamic of motor output
Power is done directly gearshift by ball-screw.
Brief description of the drawings
Fig. 1 is three-dimensional figure structure schematic representation of the present utility model；
Title in figure corresponding to sequence number is as follows：
Shift motor 1, selector fork 2, screw mandrel 3, feed screw nut 4, shift fork end 5, synchronizer 6, linear movement pick-up 7, magnetic

Embodiment
A kind of AMT automatic gear shift apparatus, is shown in Fig. 1：It includes shift motor 1, selector fork 2, each shift motor 1 it is defeated
Go out end and be fixed with screw mandrel 3, feed screw nut 4, the side of feed screw nut 4 and being fixedly connected for selector fork 2 are set with screw mandrel 3,
The shift fork end 5 of selector fork 2 be used to stirring corresponding to synchronizer 6 synchro converter ring, on the correspondence position of every piece of selector fork 2
Linear movement pick-up 7 is provided with, linear movement pick-up 7 is used to monitor drive range, feed back to controller.
Magnet arrangement 8 is disposed with selector fork 2, linear movement pick-up 7 is by the position of induced magnet structure 8 so as to reality
Apply and collect drive range information, linear movement pick-up 7 can be installed in the corresponding position of gear box casing 10 by mounting bracket 9
Put；
Synchronizer 6 is located inside gear box casing 10, and the other end of screw mandrel 3 is loaded on case of transmission by the positioning of bearing 11
10 side wall；
Feed screw nut 4 is integrated in a side position of the non-bifurcation main body of corresponding selector fork 2 so that the He of feed screw nut 4
