Background technique
On the basis of traditional mechanical formula manual transmission, by installing gearshift device actuator, clutch actuating mechanism and corresponding ECU (Electrical Control Unit) additional, traditional mechanical formula manual transmission can be changed into AMT (mechanical automatic gearbox), thereby realize the automatic speed changing of vehicle in advancing.At present, the gearshift device actuator that generally adopts mostly is hydraulic driving both at home and abroad, and hydraulic driving is had relatively high expectations to element, and its cost is higher, needs bigger arrangement space, and is especially inapplicable for the car that the space is narrow and small.Also have and use motorized motions, but the accuracy of this structure is relatively poor.
Summary of the invention
The purpose of this utility model be to provide low, the required arrangement space of a kind of cost less by motor-driven mechanical automatic gearbox gearshift device actuator, to overcome the defective of said structure.
The technical solution of the utility model is: mechanical automatic gearbox gearshift device actuator, it comprises the gear selecting drive unit, the engage a gear drive unit, the output terminal of engage a gear drive unit connects the engage a gear gear drive, the engage a gear gear drive comprises the engage a gear input shaft, the engage a gear master gear that the engage a gear input shaft connects is with the output gear of engage a gear gear; The output terminal of gear selecting drive unit connects screw mandrel, connect screw on the screw mandrel, the other end of screw mandrel is enclosed within the hollow sleeve of gearshift device actuator shaft, connects the output gear of engage a gear gear drive on the gearshift device actuator shaft, and screw is connected with output shaft one end.
This gearshift device actuator combines with gear-driven cleverly by the screw mandrel transmission, makes output shaft can realize axial displacement, finishes the gear selecting action; Can realize again rotating, finish the fork shift action; Two actions do not influence each other each other.This is simple in structure, and the efficient height is convenient to processing, is installed, and its profile is small and exquisite, is suitable for using in the mechanical automatic gearbox vehicle, is particularly suitable for using in the narrow and small car in space.

Embodiment
Present embodiment is an example structure under the technical solutions of the utility model, and the utility model is not limited 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 connects screw 4, offers draw-in groove 14 on the screw 4, and an end of output shaft 6 is stuck in the draw-in groove 14, is Spielpassung between output shaft 6 and the screw 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 screw 4 or output shaft 6.Connecting rod 18 is connected with screw 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 axis hole 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 screw 4 drives output shaft 6 vertically and does axial displacement, finishes the gear selecting action.Spielpassung between output shaft 6 and the screw draw-in groove 14 has guaranteed that output shaft can do axial motion under the axial motion of screw, and do not rotate along with rotatablely moving of screw, simultaneously, to guarantee that also rotatablely moving of output shaft also must not drive the screw rotation.Screw 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 action of putting into gear.13 of the sensors of putting into gear are exported angular displacement signal.
