And radial load.Finally, wheel rim 304 is fixed on wheel hub 201 by wheel hub 201 by 5 rim bolts 309.
The course of work of automobile-used automatic Free hub of the present invention is as follows：
As shown in Figure 7, Figure 8, when vehicle starting, driver controls control stick that transfer case is combined into preparation with 4 wheel driven row
Sail, with the increase of accelerator pedal aperture, driving force gradually increases driving automobile and accelerates starting by static, now semiaxis
The moment of torsion of 103 acquisition automotive powerplants offers simultaneously starts to rotate.For traditional time sharing automobile, because transfer case is combined,
Semiaxis 103 obtains engine drive torque by the differential mechanism of this bridge；For four motorized wheels electric automobile, this bridge two-wheeled side
Motor is controlled output driving torque.Due to being coordinated between semiaxis 103 and drive sleeve 102 by helical spline, drive sleeve 102 is again
Coordinated between one-way clutch 301 with spline, therefore after semiaxis 103 rotates, therefore drive one-way clutch 301
Inside race 306 is rotated relative to the direction of outer race 305 to extruding cylindrical roller 308, so that one-way clutch 301 is locked, will
Power passes to outer race 305, realizes that power is transmitted, then one-way clutch 301 drives wheel hub 201 to rotate by external splines,
Tire 304 is driven to start to rotate.At the same time, drive sleeve 102 is moved to the left along spline screw rod, the circular cone of drive sleeve 102
Face heads on the displacement in the vertical direction of pin 202 and moved upwards, extrusion spring 204, as drive sleeve 102 is moved to the left, displacement pin
In the circular hole of the 202 final radial equipartitions for putting in wheel hub 201, finally connect because drive sleeve 102 is moved to high order end with wheel hub 201
After touch, displacement pin 202 is parked at the big footpath of the circular conical surface of drive sleeve 102.Now, semiaxis 103 transmits driving torque by spline
To inner casing 203, inner casing 203 transfers drive torque to wheel hub 201 further through displacement pin 202.I.e. driving torque is logical through semiaxis 103
Cross one-way clutch running part and displacement pin running part two lines pass to wheel hub 201 and its wheel together.Here, lead to
Cross one-way clutch and displacement pin two parts transmit torque and can slow down the abrasion of cylindrical roller in one-way clutch jointly, it is ensured that
Reliable transmission.Now, semiaxis 103, wheel hub 201, one-way clutch 301, inner casing 203, drive sleeve 102 are the equal of one
, together as semiaxis 103 is rotated.Now, automobile is 4 wheel driven state.
When being travelled when high speed is at the uniform velocity normal in the entrance of acceleration mode automobile, now because between semiaxis 103 and wheel hub 201
Rotating speed is identical, between the two without relative rotation, also without relative rotation between drive sleeve 102 and one-way clutch 301.Now, become
Position pin 202 press against the circular conical surface of drive sleeve 102 in the case where the resets pressure of spring 204 is acted on, its pressure to drive sleeve 102 along
Circular conical surface is decomposed into the component of both direction, and one has along circular conical surface, a vertical conical face, the component perpendicular to circular conical surface
Drive sleeve 102 is push to move right the trend of reset, and this trend requires that drive sleeve 102 has relative to spline screw rod forward
Trend, when drive sleeve rotates forward, the side of the inside race 306 of one-way clutch 301 vis-a-vis outer race 305 can be caused again
To extruding cylindrical roller 308, so that one-way clutch 301 is again locked, still in 4 wheel driven state.Therefore, when automobile is with 4 wheel driven
When state moves forward, either accelerate still at the uniform velocity state, automobile can keep 4 wheel driven state, running car has been effectively ensured
Stability.
When transfer gear switches to two drive gears, because semiaxis 103 there is no driving torque, and the wheel of the bridge is another
Driven rolls forward under the driving force effect of an outer bridge, now one-way clutch 301 turn because inside and outside external member 305 and 306 is relative
Dynamic direction is makes the compression spring 307 of cylindrical roller 308 recess the angle of wedge, therefore one-way clutch 301 is disengaged and do not worked, now with unidirectionally
The drive sleeve 102 of the spline of 301 inside race of clutch 306 connection can be fixed on answering on displacement pin 202 without constraint reaction
The axial thrust load effect of the pressure of position spring 204 is lower to rotate forward an angle on one side, while moving right, conjugates the edge again of pin 202
Circular conical surface to move straight down, final displacement pin 202 is exited from wheel hub 201, and semiaxis 103 and wheel hub 201 depart from, this time-varying
State, the transfixion of semiaxis 103, so as to reduce the gear wear of differential mechanism or the electromagnetic consumable of wheel motor are driven into two.This
In, displacement pin 202 plays a part of reset.Principle when automobile drives state starting traveling from two in itself is similar to above, this
When disengaged due to one-way clutch 301, drive sleeve 102 and semiaxis 103 and its bridge master subtract transfixion with differential mechanism so that
Save reactive loss.
When pilot control gear level is to be moved backward, if now transfer gear is two drive shelves, wheel hub 201 drives in another bridge
Rotate backward, therefore, between drive sleeve 102 and one-way clutch 301 just have along extruding cylinder with vehicle body is driven under power effect
The relative rotation in the direction of roller 308, therefore, now one-way clutch 301 also transmits power.Because one-way clutch 301 is with flower
Key engagement drives drive sleeve 102 to rotate, therefore also has relative rotation, therefore drive sleeve 102 between drive sleeve 102 and spline screw rod
It is moved to the left along spline screw rod, equally, it is upward that the circular conical surface of drive sleeve 102 heads on the displacement in the vertical direction of pin 202 again
Motion, wheel hub 201 and semiaxis 103 is linked together synchronous rotary, now due to for traditional 4-wheel driven car semiaxis and differential mechanism
Rotation, or for four motorized wheels electric car wheel side rotor rotate, so when there is idle energy consumption.But, due to
Reverse travel is that small operating mode, i.e. running time are very short, therefore it is little to add up idle energy consumption.
When pilot control gear level is to be moved backward, if now transfer gear remains in 4 wheel driven shelves reversing, due to half
Axle 103 obtains the reverse drive torque or motor reverse drive torque that engine is sent through speed changer, drives drive sleeve 102 pre- anti-
To rotation, because the relative package assembly 305 of 301 internal member of one-way clutch 306 being connected with the external splines of drive sleeve 102 reversely revolves
Turn, now, the cylindrical roller 308 of one-way clutch 301 under the frictional force effect of internal member 306 compression spring 307 to exiting wedge
The direction movement at angle, therefore, the inner-outer sleeve of one-way clutch 301 is disengaged and not worked, now due to no constraint reaction, drive sleeve
102 abut against right side in company with the rotation of the synchronous backward of semiaxis 103, and displacement pin 202, which rests on not rise to connect at the path of drive sleeve 102, to be made
With wheel hub 201 is with semiaxis 103 without mechanical connection, and driving torque can not pass to the bridge wheel, and substantial 4 wheel driven pattern is not acted as
With automobile still drives traveling for two.It is less demanding to automobile passability during due to reverse travel, so when on automobile passability influence
Less., can be using mechanical linkage which controls or control logic control reversing automobile traveling to avoid influenceing driver's driving experience
When automatically switch to two drive patterns.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
