Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of bidirectional automatic gear shifting transmission gear for electric motor, more particularly to
A kind of buffer gear in bidirectional automatic gear shifting transmission gear for electric motor.
Background technology
There is climbing in use to overcome conventional brush-less wheel hub motor, brushless differential speed motor or series machine
The defect of the aspect such as performance and speed, begins to use bidirectional automatic gear shifting motor transmission mechanism in electro-tricycle, it is by single
The advance or retroversion of electro-tricycle are realized to the cooperation of dop and advance isolator and retrogressing isolator, but, at present
The bidirectional automatic gear shifting motor transmission mechanism of this structure has not compact structure, parts distribution dispersion, space hold mistake
Big the problems such as.
And in order to solve the above problems, the applicant once applied for a kind of [application of bidirectional automatic gear shifting transmission gear for electric motor
Number：201510424829.9], it includes housing and the main shaft and input shaft that are axially fixed in housing, is cased with main shaft
Isolator, isolator includes outer shroud and the inner ring fixed with main shaft, and axial restraint has gear on main shaft, and connection is fixed with outer shroud
Part, is circumferentially fixed with driving member on main shaft, rotating shaft drives outer shroud and pinion rotation, and rotating shaft and outer shroud simultaneously by gear mechanism
Between gearratio of the gearratio more than rotating shaft and gear；When rotating shaft is rotated counterclockwise, isolator is in slipping state, connection
Part and driving member link by located at combining mechanism between the two；When rotating shaft is rotated clockwise, connector and driving member are logical
The separating mechanism crossed in housing is separated and keeps released state；When rotating shaft high-speed rotation clockwise, gear and inner ring are logical
Cross the gear linkage located between the two.The bidirectional automatic gear shifting transmission gear for electric motor is realizing electro-tricycle ahead and astern
On the premise of, the whole transmission device space to be taken is reduced well, overall structure is become simpler.
But, above-mentioned bidirectional automatic gear shifting transmission gear for electric motor there is also some defects：In bidirectional automatic gear shifting electricity
In machine transmission device, gear includes the planetary gears being set on main shaft and is set on main shaft and mutually solid with gear
Fixed annular slab, annular slab is located between gear and planetary gears, and planetary gears includes gear ring, sun gear and planet
Frame, sun gear is connected by the axle sleeve being set on main shaft with gear, and planet carrier is circumferentially fixed with inner ring, on the end face of annular slab
The hinged place for being hinged with centripetal piece, centripetal piece at least 2 pieces and circumferentially distributed, each centripetal piece and annular slab is equipped with torsion
Spring, is arranged with tubular supporter on axle sleeve, and supporter one end offsets with annular slab, and centripetal piece is provided with and supporter between
The guidance set two moved axially to planet carrier direction by centripetal piece of rotation drive supporter, is set between gear ring and planet carrier
There are the attachment structure that can make gear ring and planet carrier linkage when supporter is moved axially to planet carrier direction, supporter and planet carrier
Between be provided with compression spring six.When rotating shaft drives high-speed gear to rotate, gear drives ring gear against rotation by axle sleeve and sun gear,
Supporter is moved towards planet carrier and planet carrier is passed through attachment structure shape with gear ring by the effect of guidance set two simultaneously
Into linkage, thus gear ring drives planet carrier together to rotate, and because planet carrier is circumferentially fixed with inner ring, inner ring is mutually fixed with main shaft,
Therefore planet carrier will pass through inner ring drive main shaft and be rotated.It is however noted that, passed in the bidirectional automatic gear shifting motor
By setting the limited post of protrusion in planet carrier and spacing hole being set on the end face of inner ring in dynamic device, limited post is inserted into
So that planet carrier is circumferentially fixed with annular in spacing hole.But carry out circumferentially fixed just causing planet carrier using limited post
It is rigidly connected between inner ring, then when planet carrier drives inner ring to start to rotate, can be produced between limited post and inner ring
Rigid collision, so as to produce larger noise.
