Abstract
The utility model relates to a select gear shift actuating mechanism, including selection shelves motor, selection shelves lead screw, selection shelves nut, gear shift motor, gear shift lead screw, gear shift nut, gear shift nut cover, round pin axle, still including selecting the selector fork and selecting the selector fork axle. Compared with the prior art, the utility model has the advantages of it is following: the power of selection shelves motor can be used in selects the selector fork epaxial, selects the selector fork axle except rotating around its axis, can also follow its axis and move.
Description
Technical field
The utility model relates to automobile AMT, especially relates to a kind of gear-selecting and shifting executing mechanism of automobile AMT.
Background technique
Electrical control automatic manual transmission case AMT a kind ofly replaces manpower to complete clutch by Mechatronic Systems and selects the gearbox of gear-change operation, obtains application and universal in recent years gradually.Gear-selecting and shifting executing mechanism is the important component part of AMT.
The general approach of existing gear-selecting and shifting executing mechanism is: during gear selecting, by driving mechanism, the rotary motion of step electric machine is become straight line motion, then drives and selects gear shift to refer to slide on square shaft or drive shifting block translation on main shaft; During gear shift, by driving mechanism, the rotary motion of gear shifting motor is become straight line motion, then drive gear shift shifting block swing around square shaft or drive shifting block to rotate around the spindle.In these schemes, the power of step electric machine does not act directly on main shaft or square shaft, and main shaft or square shaft can only rotate around its axis, and can not move along its axis.
Model utility content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of gear-selecting and shifting executing mechanism is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of gear-selecting and shifting executing mechanism, comprises step electric machine, gear selecting screw mandrel, gear selecting nut, gear shifting motor, gear shift screw mandrel, gear shift nut, gear shift nut sleeve, bearing pin, also comprises and select range fork and select gear shift fork shaft.
Described step electric machine is connected with described gear selecting screw mandrel, described gear selecting screw mandrel is connected with described gear selecting nut, described gear shifting motor is connected with described gear shift screw mandrel, and described gear shift screw mandrel is connected with described gear shift nut, and described gear shift nut is connected with described gear shift nut sleeve.
Described range fork one end of selecting is connected with described gear selecting nut, and the other end is connected by described bearing pin with described gear shift nut sleeve, is connected again with the described gear shift fork shaft that selects simultaneously.
Described selects one end of range fork fluted, and described gear selecting nut snaps fits into described selecting in the groove of range fork, or one end of described gear selecting nut is fluted, and the described range fork that selects snaps fits in the groove of described gear selecting nut.
Described select range fork and described select gear shift fork shaft by fastening piece or spline joint.
Compared with prior art, the utility model has the following advantages: the power of step electric machine can act on to be selected on gear shift fork shaft, selects gear shift fork shaft except rotating around its axis, can also move along its axis.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 for step electric machine, 2 for gear selecting screw mandrel, 3 for gear selecting nut, 4 for gear shifting motor, 5 for gear shift screw mandrel, 6 for gear shift nut, 7 for gear shift nut sleeve, 8 for bearing pin, 9 for selecting range fork, 10 for selecting gear shift fork shaft.
Embodiment
Below the utility model is described further.
Embodiment
A kind of gear-selecting and shifting executing mechanism, as shown in Figure 1, comprises step electric machine 1, gear selecting screw mandrel 2, gear selecting nut 3, gear shifting motor 4, gear shift screw mandrel 5, gear shift nut 6, gear shift nut sleeve 7, bearing pin 8, selects range fork 9, selects gear shift fork shaft 10.
Step electric machine 1 is connected with gear selecting screw mandrel 2, and gear selecting screw mandrel 2 is connected with gear selecting nut 3, and gear shifting motor 4 is connected with gear shift screw mandrel 5, and gear shift screw mandrel 5 is connected with gear shift nut 6, and gear shift nut 6 is connected with gear shift nut sleeve 7.Range fork 9 is selected to be connected with gear shift nut sleeve 7 by bearing pin 8.Range fork 9 is selected to be connected by fastening piece with selecting gear shift fork shaft 10.Select one end of range fork 9 fluted, gear selecting nut 3 clamps in the groove of selected range fork 9.
Working principle is as follows: during gear selecting, and step electric machine 1 rotates and drives gear selecting screw mandrel 2 to rotate, and gear selecting screw mandrel 2 rotates and drives gear selecting nut 3 to move, and gear selecting nut 3 moves drive and selects range fork 9 to move, and selects range fork 9 to move drive and selects gear shift fork shaft 10 to move along its axis; During gear shift, gear shifting motor 4 rotating band is moved grade screw mandrel 5 and is rotated, and gear shift screw mandrel 5 rotating band is moved grade nut 6 and moved, and gear shift nut 6 moves gear shift nut sleeve 7 and moves, gear shift nut sleeve 7 moves drive and selects range fork 9 to rotate, and selects range fork 9 to rotate drive and selects gear shift fork shaft 10 to rotate around its axis.
Above embodiment is preferred version of the present utility model, not does any pro forma restriction to the utility model, under the prerequisite not exceeding the technological scheme described in claim, also have other variant and remodeling.
