Mode push shaft coupling cam compression elastic piece, and make to unclamp inside clutch.
In this power device it is some can action component mainly using main casing as brace foundation, pass through some axis of rolling
It holds and is supported in main casing.This power device is used as power source, can apply in fields such as electric vehicle, lathes, for for
Power execution unit provides power.
Further, the drive sleeve includes left set and right set, and the opposite end face docking of both left set and right set is connected in
Together, the supporting surface is formed between left set and right set.Drive sleeve is made into split type structure, convenient for transmission is set on
In main casing, and convenient for the assembly of some components with drive sleeve driving coupling.
Further, support ring has been gripped between the opposite end face of both left set and right set, supporting surface is formed in branch
On the end face of pushing out ring.Supporting surface is formed in support ring, the production of ring is supported convenient for the material of selection excellent wear resistance, favorably
It in saving cost of manufacture, and can effectively mitigate the weight of drive sleeve, reduce energy consumption.
Further, clutch is Chong Die with right set axial position, and left set is located at the outside of clutch axial position, support ring
It is step surface cooperation with the opposite end face of both left sets.This reasonable structural arrangement, the cooperation between ring easy to support and left set,
And the fitment stability of the two is good.
Further, it is right put on towards on the end outer peripheral surface of left set integrally formed with export-oriented bulge loop, export-oriented bulge loop it is outer
Circumferential surface is equipped with several passive tooths, the output shaft driving coupling of passive tooth and motor；In the outer end of left set integrally formed with contracting

Specific embodiment
See Fig. 1, this motor self-adapting power device, including main casing 25, sub-shell 2 is fixed on main casing 25, in pair
Motor 1 is equipped in shell 2, the output shaft 19 in motor 1 is extend into main casing 25.Main shaft is rotatably provided in main casing 25
13, one end of main shaft 13 reaches the outside of main casing 25.Driving gear 18 is fixed on the end of output shaft 19, in main casing
Side in body 25 close to output shaft 19 is rotatably provided with the first cluster gear 17, driving gear 18 and the first cluster gear 17
Gear wheel is meshed.The drive sleeve of tubular is equipped in main casing 25, main shaft 13, which is worn, to be connect at the axial location of drive sleeve.Transmission
Circumferentially arranged with a circle passive tooth 10 on the outer peripheral surface of set, passive tooth 10 is meshed with the pinion gear of the first cluster gear 17, passes
Driving coupling between dynamic set and main shaft 13.
Clutch 11 is socketed on main shaft 13, clutch 11 is by multi-plate friction plate 111 and is arranged at intervals on friction plate 111
Between wear plate 112 constitute, wear plate 112 be it is made of iron, be circumferential driving coupling between wear plate 112 and main shaft 13.
It is equipped with supporting surface in the inside of drive sleeve, supporting surface is perpendicular to the axis of shaft, and supporting surface is for directly and a piece of
Friction plate 111 is bonded, and after compressing clutch 11 towards supporting surface, the power in drive sleeve can be transmitted to by clutch 11
On main shaft 13.After removal is to the axial compressive force of clutch 11, due to 11 internal loose of clutch, friction plate 111 and wear plate
It can only occur to slide relatively between 112, without realizing the power transmitting on macroeconomic significance.
Elastic component is equipped in drive sleeve, elastic force the acting axially on clutch 11 along drive sleeve of elastic component is used for
Clutch 11 is pressed to supporting surface, and makes to compress inside clutch 11, it can be achieved that drive sleeve transmits power by clutch 11
Onto main shaft 13.
In addition between drive sleeve and main shaft 13 can by clutch 11 realize high-speed drive other than, drive sleeve also with deceleration mechanism
Driving coupling, deceleration mechanism is by realizing driving coupling between one-way driving mechanism and main shaft 13, to realize drive sleeve and master
Low speed rotation between axis 13.There are two types of transmission modes between drive sleeve and main shaft 13, therefore also need that corresponding construction is arranged, and come
It realizes separating for clutch 11, and cooperates one-way driving mechanism, to realize the switching between two kinds of transmission modes.
Therefore, it is socketed with shaft coupling cam 42 with gap on main shaft 13, shaft coupling cam 42 can be axially moved on main shaft 13.
It may be provided with spline structure between shaft coupling cam 42 and main shaft 13, be also possible to flat key shown in figure, and realize shaft coupling cam
Circumferential driving coupling between 42 and main shaft 13.Clutch 11 is socketed in gap on shaft coupling cam 42, wear-resisting in clutch 11
Couple between piece 112 and shaft coupling cam 42 for spline, and can realize the circumferential transmission between clutch 11 and main shaft 13.
It is equipped with fixed cam 41 on main shaft 13, fixes the opposite axial restraint on main shaft 13 of shaft coupling cam 42 of cam 41,
Fixed cam 41 and the circumferential driving coupling of main shaft 13.It is equipped with and cooperates with the opposite end of shaft coupling cam 42 in fixed cam 41
Inclined opening structure, inclined opening structure is actually placed on fixed cam 41 and the opposite end face of shaft coupling cam 42 and moves towards consistent spiral shell
Revolve inclined-plane.The elastic component acts on shaft coupling cam 42 simultaneously, and under the action of inclined opening structure, fixed cam 41 is to follow
The mode that main shaft 13 rotates pushes 42 compression elastic piece of shaft coupling cam, and elastic component releases the compression to clutch 11, clutch
It friction plate 111, wear plate 112 in 11 and is unclamped between the supporting surface in drive sleeve.
Angle is circumferentially rotated relatively between shaft coupling cam 42 and fixed cam 41 to limit, and exempts from them and circumferentially turns relatively
It is dynamic to be excessively equipped with the seam allowance further relatively rotated for limiting fixed cam 41 and shaft coupling cam 42 at inclined opening structure, two
After seam allowance on person fits together, fixed cam 41 and shaft coupling cam 42 are equivalent to a whole driving member.
Actual using upper, start and load increase in the case where, the power of motor 1 passes through the first cluster gear 17
It is transmitted on axle sleeve 21, the resistive torque as suffered by main shaft 13 is big, and fixed cam 41 pushes shaft coupling convex by inclined opening structure
Wheel 42 is axially moved towards the direction of compression elastic piece, and clutch 11 separates, and drive sleeve directly passes through deceleration mechanism and drives unidirectionally
Transmission mechanism movement, the revolving speed of one-way driving mechanism at this time are greater than the velocity of rotation of main shaft 13, and one-way driving mechanism drives
Main shaft 13 slowly runs, and power transmitting torque at this time is big, has just adapted to the stress condition of main shaft 13.If the movement of main shaft 13 is flat
After slow, the resistive torque that main shaft 13 is subject to becomes smaller, and the driving torque between fixed cam 41 and shaft coupling cam 42 is small, in angle and
Under the acting in opposition of elastic component, shaft coupling cam 42 is moved towards fixed 41 direction of cam, and elastic component compresses clutch 11 again, is moved
Power can be directly passed on shaft coupling cam 42 from drive sleeve by clutch 11, shaft coupling cam 42, fixed cam 41 and main shaft
13 revolving speed is consistent, and main shaft 13 is equivalent to relative to one-way driving mechanism to be rotated backward, and one-way driving mechanism does not work.
Although being driven with two kinds of transmission modes, in switching, since the deformation of elastic component is a gradual change
Process, the axial movement of shaft coupling cam 42 is also just to be able to achieve being totally released for clutch 11 by a certain distance, therefore,
Switching between the two transmission mode does not have an apparent separation, in pilot process, perhaps will appear two kinds of transmissions
The ride comfort of transmission can still be maintained in transmission mode handoff procedure in the phenomenon that mode coexists.
