Description
Technical field
The present invention relates to selecting, changing shifts of automobile speed changer actuator, relate in particular to the gear-selecting and shifting executing mechanism of a kind of electric control mechanical type automatic speed variator (AMT).
Background technique
Electric control mechanical type automatic speed variator (AMT) is to improve on traditional manual gear formula speed changer basis and come, it has the advantage of high fuel economy and low emission, and kept that the gear-driven efficient height of former manual transmission, cost are low, simple in structure, the strong point of easy manufacturing, therefore more and more come into one's own.The gear-shifting actuating mechanism of the electric control mechanical speed changer that occurs was made up of gear selecting and two steps of gear shift at present, and drive unit is controlled by control unit, and the motion of mechanism signal feeds back to control unit by signal output apparatus output.The action output of gear selecting gear shift is to use the same axis to carry out, moving direction difference owing to output shaft in two steps, therefore the arrangement of the selection of actuator's kind of drive and moving element structure is very complicated, if select unreasonable, not only can make entire mechanism take bigger space, and can influence shift quality and shift time.
Summary of the invention
For addressing the above problem, the invention provides a kind of compact structure, the automatic speed variator gear-selecting and shifting executing mechanism that transmission efficiency is higher.
Automatic speed variator gear-selecting and shifting executing mechanism of the present invention, comprise gear shift drive unit, gear selecting drive unit, shift signal output unit, gear selecting signal output apparatus, first gear drive and output shaft, wherein, the gear shift drive unit drives output shaft by first gear drive, it is characterized in that:
Also comprise second gear drive and gear selecting signal input gear;
Form tooth-strip part on the described output shaft, and with described meshing connection of gear selecting drive unit; Described gear selecting signal output apparatus connects tooth-strip part by gear selecting signal input gear mesh, produces synchronization motion with the gear selecting drive unit;
It is splined shaft that first stage building is arranged on the described output shaft in addition, the length of splined shaft at least should be greater than the stroke of output shaft axial motion, is connected by spline fitted between the gear of output end of the input end gear of described second gear drive and described first gear drive and the described output shaft; Described shift signal output unit is connected on first gear drive by second gear drive, produces synchronization motion with the gear shift drive unit.
As a further improvement on the present invention, the gear of output end of the input end gear of described second gear drive and described first gear drive is made as integral structure, and with described output shaft between be connected by spline fitted.
The advantage of automatic speed variator gear-selecting and shifting executing mechanism of the present invention is:
(1) tooth-strip part is set on output shaft, and makes it to import gear engagement with the gear of output end and the gear selecting signal of gear selecting drive unit simultaneously, thereby gear selecting is driven and gear selecting signal output synchronization motion, simplify the gear selecting driving mechanism and also make it compact structure.
(2) the input design of gears of the gear drive of the output gear of the gear drive of gear shift drive unit and shift signal output unit is an integral structure, and with output shaft between be connected by spline fitted; The integral type gear is provided with internal spline, matches with the external splines of output shaft, when needing gear shift, under the effect of gear shifting motor, can realize the rotation of output shaft by spline fitted; When needing gear selecting, the gear selecting motor drives the output shaft moving linearly by gear rack, and can't drive two gear drive motions because spline is a Spielpassung this moment, and the gear selecting gear shift is not disturbed mutually.
(3) this mechanism structure is simply compact, and the transmission efficiency height can fully adapt to the gear shift requirement under the various different operating modes, is suitable for electric control mechanical type automatic speed variator and uses.
Description of drawings
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
Accompanying drawing 1 is the structural representation of automatic speed variator gear-selecting and shifting executing mechanism of the present invention.
Embodiment
Mode of execution shown in the drawings is a kind of embodiment under the technical solution of the present invention.
In conjunction with the accompanying drawings, the gear shift drive unit that selects of the present invention is motor, selects the shift signal output unit to be sensor.Automatic speed variator gear-selecting and shifting executing mechanism of the present invention comprises: gear shifting motor 1, first gear drive 2, second gear drive 3, gear shift sensor 4, gear selecting motor 5, the input of gear selecting signal gear 6, gear selecting sensor 7 and output shaft 8.Wherein, first gear drive and second gear drive all can select whether to use train of reduction gears, and in the present embodiment, first gear drive 2 has been selected train of reduction gears for use, and second gear drive 3 is not selected train of reduction gears for use.
Shown in accompanying drawing, form the tooth-strip part 8a of annular on the output shaft 8, the length of tooth-strip part 8a at least should be greater than the stroke of output shaft axial motion, gear on gear selecting motor 5 output shafts is in the side and its meshing connection of tooth-strip part 8a, the meshing gear selecting signal input gear 6 that is connected with of relative opposite side, the input shaft of gear selecting sensor 7 connects gear selecting signal input gear 6; It is splined shaft 8b that first stage building is arranged on the output shaft 8 in addition, the length of splined shaft 8b at least should be greater than the stroke of output shaft 8 axial motions, gear of output end 2a of first gear drive 2 and the input end gear 3a of second gear drive 3 are connected on it, these two gears are set as the structure of integral type and internal spline are set thereon, and corresponding matching is connected on the splined shaft 8b; The gear of output end 3b that the input end of first gear drive 2 connects gear shifting motor 1, the second gear drive 3 is connected on the input shaft of gear shift sensor.
