Summary of the invention
The purpose of this utility model be to provide a kind of gearshift more steadily, the universal electric motor car AMT gearshift of high, the longer service life of reliability.
To achieve these goals, the utility model adopts following technological scheme: a kind of universal electric motor car AMT gearshift comprises gearbox, described gearbox is provided with shift lever, described shift lever extends to gearbox in gearbox, outside gearbox, gear shifting motor is installed, described shift motor is connected with speed reducer, described speed reducer is provided with housing, main shaft is rotatably supported in housing, housing is provided with and extends to through hole outside housing for main shaft, main shaft one end is provided with the reduction gear of rotating with spindle synchronous, described reduction gear engages with the output gear be arranged on gear shifting motor shaft, and the number of teeth of reduction gear is more than the number of teeth of output gear, it is outer and be provided with screw structure that the other end of described main shaft extends to housing, described screw structure is threaded with guide pillar, the rotation of main shaft can cause guide pillar to move axially, described guide pillar is connected with the shift lever of gearbox.Adopt gear first stage to slow down between shift motor and main shaft, make moment of torsion obtain increasing to make gearshift more steady, and make each gearshift cause the frictionally damage of gear to reduce, thus make that reliability of the present utility model is higher, longer service life.
As preferably, the housing of described speed reducer is made up of base and shell, and described base and gear shifting motor end cap are fixed, and shell lower end is formed with the groove matched with pedestal profiles, passes through screw fastening between shell and base.Housing can be protected speed reducer, and prevents the oil leak in speed reducer.
As preferably, described main shaft is rotatably supported in the housing of speed reducer by two plane bearings.
As preferably, be provided with axle sleeve between described through hole and main shaft, between main shaft and axle sleeve, form rotary support.Axle sleeve can make main shaft support ground more steady.
As preferably, described main shaft extends to outside the one end outside housing and is provided with overcoat, one end of overcoat and housing abut, described guide pillar does axial motion in the gap of overcoat and main shaft, the other end of overcoat is provided with upper cover, be covered with internal projecting ring on described, this end that described guide pillar corresponds to overcoat is provided with outer bulge loop, and the external diameter of outer bulge loop is greater than the internal diameter of internal projecting ring.Position-limiting action is played in outer bulge loop and internal projecting ring cooperation, makes guide pillar depart from main shaft.
As preferably, described upper cover is fixed by sunk screw and overcoat.Upper cover is fixedly more convenient for processing and keeping in repair by sunk screw and overcoat.
As preferably, the housing upper end of described speed reducer is formed with cylindrical upper convex body, and described through hole is arranged in convex body, and described overcoat and the external wall of epirelief are socketed.Be provided with epirelief physical efficiency and facilitate fixing between overcoat and housing.
As preferably, be embedded with in described guide pillar and press-fit nut, by press-fiting nut and screw structure screw thread matches between guide pillar and main shaft.Make nut make axial linear movement by main axis, thus drive the guide pillar fixing with nut to make axial linear movement.
The utility model has the advantages that and can make gearshift more steadily and reliability is high, longer service life.
