Embodiment
Present embodiment is an example structure under the technical solution of the present invention, the invention is not restricted to following example structure.
As shown in Figure 1, the gear selecting drive unit is a gear selecting motor 1, and this device can select whether connect speed reducer as requested, does not select in the present embodiment.The engage a gear drive unit is engage a gear motor and speed reducer 2, and whether speed reducer needs also can select as requested, select tape speed reducer in the present embodiment.
Following structure is set: engage a gear gear drive, spindle gear in the housing 11.The engage a gear gear drive comprises the engage a gear input shaft 9 that is connected with engage a gear motor and speed reducer 2 output terminals, and the engage a gear master gear 10 that engage a gear input shaft 9 connects is with the output gear 12 of engage a gear master gear 10 engagements; Output gear 12 is connected on the output shaft 6.Spindle gear comprises the screw mandrel 3 that is connected with the output shaft of gear selecting motor 1, and screw mandrel 3 attaching nuts 4 offer draw-in groove 14 on the nut 4, and an end of output shaft 6 is stuck in the draw-in groove 14, is Spielpassung between output shaft 6 and the nut draw-in groove 14.
Engage a gear input shaft 9 also connects engage a gear sensor 13, and promptly the output shaft of engage a gear motor and speed reducer 2 connects engage a gear sensor 13, and engage a gear sensor 13 is outside housing 11.
The detection device of output shaft axial displacement can be various structural types can detect gear selecting the time, the device of output shaft 6 axial displacements.The following structural type of present embodiment: comprise connecting rod 18, establish axial tooth bar 15 on the connecting rod 18, axially tooth bar 15 meshes with gear selecting sensor gear 5, gear selecting sensor gear 5 is connected on the gear selecting sensor input shaft 7, connect gear selecting sensor 8 on the gear selecting sensor input shaft 7, connecting rod 18 is connected with nut 4 or output shaft 6.Connecting rod 18 is connected with nut 4 in the present embodiment.Gear selecting sensor 8 is located at outside the housing 11.Establish guide rail 19 in the housing 11,19 on guide rail is established axially directed groove 16.The other end of connecting rod 18 is embedded in the axially directed groove 16.
As shown in Figure 2, output shaft 6 one ends are established axial bore 17, and screw mandrel 3 is enclosed within the axial bore 17 of output shaft 6.
The working principle of this gearshift device actuator is as follows: during gear selecting, gear selecting motor 1 drives screw mandrel 3 and rotates, and nut 4 drives output shaft 6 vertically and does axial displacement, finishes the gear selecting action.Spielpassung between output shaft 6 and the nut draw-in groove 14 has guaranteed that output shaft can do axial motion under the axial motion of nut, and do not rotate along with rotatablely moving of nut, simultaneously, to guarantee that also rotatablely moving of output shaft also must not drive the nut rotation.Nut 4 drivening rod 18 is simultaneously made axial linear movement, and the displacement amount signal of output shaft 6 is exported by gear selecting sensor 8.During engage a gear, engage a gear motor driving engage a gear master gear drives output gear 12 and rotates, and 12 of output gears drive output shaft 6 rotations and finish the engage a gear action.13 of engage a gear sensors are exported angular displacement signal.
