[specific embodiment]
Below in conjunction with the accompanying drawings this utility model is described in further detail:
Referring to Fig. 1, this utility model is assemblied in automatic gear-box it is desirable to overall dimensions should be as little as possible, is beneficial to biography
Dynamic system and arrangement, therefore, using putting into gear, motor 1 intersects placement with gear-selecting cylinder 11, from high torque motor as extension
Gear motor 1, little cylinder is as gear-selecting cylinder 11.
As shown in figure 1, the motor 1 of putting into gear passes through interior hexagonal axis hole connected mode transmitting torque, gearshift with ball-screw 2
Bar 3 passes through spline connection with nut shifting block 4, gear shifting pulling head 5 respectively.Thrust bearing 6 is used for limiting the dominant bit of feed screw nut 7
Move, the stroke so that it is determined that maximum of this mechanism is put into gear.By setting mechanical position limitation in gear-selecting cylinder 11 it may be determined that block selecting
The maximum block selecting stroke of piston 9.
When putting into gear, when ball-screw 2 rotates around own axes under the drive of motor 1 of putting into gear, feed screw nut 7 is in ball
Move along a straight line on the axis direction of leading screw 2.Now, the swaying direction of nut shifting block 4 and leading screw axis direction are orthogonality relation,
Because gear level 3 is supported in manipulation device housing by deep groove ball bearing 8, when nut shifting block 4 swings, made by spline connection
Obtain gear level 3 to swing, gear level 3 makes gear shifting pulling head 5 swing by spline, thus completing operation of putting into gear.Now, angular displacement passes
Sensor 12 gathers the angle that gear level 3 turns over, and can draw stroke of putting into gear by calculating, stroke of putting into gear is carried out with target stroke
Feedback ratio is relatively, it is possible to achieve error compensation.
During block selecting, enter gear-selecting cylinder 11 by solenoid valve control gases at high pressure from import/exhaust mouth, promote block selecting piston 9
Reach specified location, complete block selecting.Now, linear displacement transducer 10 collects block selecting stroke, by displacement and displacement of targets
Carry out feedback ratio relatively, it is possible to achieve the error compensation of displacement.
It is controlled by ball-screw 2 and block selecting due to completing the nut shifting block 4 put into gear and the gear shifting pulling head 5 completing block selecting
Piston 9, when this manipulation device works, puts into gear motor 1 and gear-selecting cylinder 11 can independently be controlled, when shortening shifting
Between.In addition, ball-screw 2 and gear-selecting cylinder 11 can be with arranged crosswise, that is, both rotation axiss are that two orthogonal antarafacials are straight
Line, can reduce the external dimensions of manipulation device to greatest extent.Due to this mechanism had concurrently the control accuracy of power driven system with
The low cost of pneumatic system, high reliability, reduce the cost of sleeve mechanism, improve reliability.
Above content only illustrates technological thought of the present utility model it is impossible to limit protection model of the present utility model with this
Enclose, every according to the utility model proposes technological thought, any change done on the basis of technical scheme, each fall within this reality
Within protection domain with new claims.
