Description
Technical field
The invention belongs to field of mechanical technique, is related to a kind of transmission mechanism of bi-directional variable speed motor.
Background technology
The transmission mechanism of bi-directional variable speed motor be applied to electro-tricycle in, it by unidirectional dop it is isostructural cooperation come
The advance or retroversion of electro-tricycle are realized, still, the transmission mechanism parts distribution of this structure is scattered, space-consuming mistake
It is more.So applicant devises a kind of bidirectional automatic gear shifting transmission gear for electric motor and has applied for Chinese patent (its Application No.：
CN201520526628.5；Its notification number is：CN204900704U), the transmission device is equal by each parts of total
It is distributed on the axis of main shaft, reduces the gap between each parts, reduce space-consuming.But the transmission device
In separating mechanism require high for the assembly precision of each parts, such as assemble not in place, may cause in separating mechanism
Driving member can not keep released state between connector, and then influence the safety in utilization of whole transmission device.
Therefore, applicant is improved for previous scheme, a kind of bidirectional automatic gear shifting motor transmission has been redesigned
Device has simultaneously applied for Chinese patent (its Application No.：201620877779.X；Its notification number is：CN205896057U), the biography
Dynamic device includes power transmission shaft and the driving cog being set on the outside of power transmission shaft, and adapter sleeve is fixed with driving cog, is gone back on power transmission shaft
Drive sleeve is connected with by spline, be provided between drive sleeve and adapter sleeve makes drive sleeve and connection when power transmission shaft rotates clockwise
Cover the combining mechanism of linkage and drive sleeve is separated with adapter sleeve when power transmission shaft rotates counterclockwise and make drive sleeve upward
The disengagement structure mutually disengaged with power transmission shaft, adapter sleeve are provided with unidirectional ring outside, are provided between adapter sleeve and unidirectional ring and work as power transmission shaft
The one-way mechanism for making adapter sleeve be combined with unidirectional ring when rotating clockwise, there is on unidirectional ring the stop part to raise up, pass
Dynamic set lower end edge has downwardly projecting butting section, drive sleeve is disengaged upwards with power transmission shaft when power transmission shaft rotates counterclockwise
When, butting section is resisted against on stop part and makes drive sleeve holding and power transmission shaft disengaged condition, and between butting section and stop part
Provided with butting section is made when power transmission shaft rotates counterclockwise the barrier structure of state is held against with stop part.The transmission device passes through
The requirement of machining accuracy when setting the mode of barrier structure to reduce assembling between the butting section and stop part being integrally machined out,
Improve security.
However, the transmission device when carrying out reverse gear, that is, the adapter sleeve being fixed on driving cog is mutually tied with drive sleeve
Close, the power of driving cog is passed sequentially through into adapter sleeve, when drive sleeve is transferred to power transmission shaft, because leading between adapter sleeve and drive sleeve
Cross the dentation guide part with arc-shaped recliner face to be combined, and the guide part also acts as makes adapter sleeve and drive sleeve along inclining
Inclined-plane disengages, so the inclined plane of guide part is longer, i.e., the confession formed between two neighboring guide part be caught in the bayonet socket of combination compared with
Greatly, in actual use, often with reference to not in place, the situation rocked or even disengaged between driving cog and drive sleeve easily occurs,
Job stability is poor.
The content of the invention
The purpose of the present invention is in view of the above-mentioned problems existing in the prior art, it is proposed that a kind of transmission of bi-directional variable speed motor
Mechanism, technical problem to be solved are how to make vehicle in power transmission structure when reversing gear with reference to more stable.
The purpose of the present invention can be realized by following technical proposal：
The transmission mechanism of bi-directional variable speed motor, including main shaft, be set in outside main shaft and the inner ring circumferentially fixed with main shaft, set
The outer shroud being located on the outside of inner ring and the combined cover being set on the outside of main shaft, unidirectional knot is provided between the inner ring and outer shroud
Structure, being provided between the combined cover and outer shroud makes combined cover when outer shroud rotates to the disengagement knot away from the movement of outer shroud direction
Structure, transmission mechanism also include can make above-mentioned combined cover to the close elastic component one of the outer shroud, it is characterised in that the inner ring with
Be provided with engaging member and elastic component two between outer shroud, the combined cover to outer shroud it is close when can drive on the engaging member overcomes
State the elastic force movement of elastic component two and make inner ring and outer rings circumferentially fixed.
During the transmission mechanism work of this bi-directional variable speed motor, by outside there is the outer shroud of teeth persistently to receive the dynamic of transmission
Power, power is exported by main shaft.When vehicle switches to gear advance, outer shroud receives passing power and rotated counterclockwise, inner ring and outer rings
Between check configuration be combined both, the power of outer shroud is directly transferred to output power at main shaft by inner ring, passes herein
During dynamic, combined cover makes combined cover mobile to the direction away from outer shroud in the presence of disengagement structure and mutually disengaged with outer shroud,
Engaging member is not affected by other active forces, only drives engaging member to act by the elastic force effect of elastic component two and makes engaging member not by outer shroud
It is circumferentially fixed with inner ring；When vehicle switches to the advance of two gears, power is transferred on main shaft by two gear transmission mechanisms, passes through main shaft
High-speed rotation outputs power, and now, inner ring rotates counterclockwise at a high speed with main shaft, and outer shroud edge slowly runs counterclockwise, inner ring
Rotating speed be higher than outer shroud, check configuration between the two causes both to skid, and engaging member keeps uncombined state, ensures two gears
The normal transmission of power transmission；When vehicle, which switches to, to reverse gear, outer shroud receives power and rotated clockwise, between inner ring and outer rings
Check configuration to skid between the two, and trip gear no longer disengages combined cover, and combined cover acts in the elastic force of elastic component one
It is lower close to outer shroud direction, and promote engaging member to overcome the elastic force of elastic component two mobile and make inner ring and outer rings circumferentially fixed, outside
