Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to specification word to make those skilled in the art.
As shown in Figure 1, the invention provides a kind of automobile-used automatic Free hub, this automobile-used automatic Free hub is primarily of three large drive part compositions, be respectively semiaxis drive part, displacement pin drive part and overrunning clutch drive part, comprise semiaxis 103, inner casing 203, drive sleeve 102, displacement pin 202, overrunning clutch 301 and wheel hub 201.
As shown in Figure 2, semiaxis 103 is made up of three sections of axle journals, and be high order end optical axis, intermediate conveyor screw shape spline screw rod and right-hand member splined shaft composition respectively, axle journal from left to right increases successively.Semiaxis 103 is matched with its high order end optical axis by bearing 101, plays the effect supporting semiaxis 103.Semiaxis 103 right-hand member large diameter portion and inner casing 203 are coaxially fixed together by spline, and semiaxis 103 for receiving the power of automobile, output torque, and drives inner casing 203 to rotate together.
Drive sleeve 102 is in spindle, and its left end is spline, middle pilot pin cylindrical body, and right-hand member is a cone, and cone smallest cross-sectional is less than mediate cylindrical axle journal, has formed a shaft shoulder, and this shaft shoulder plays the effect of restriction displacement pin 202 displacement.Be provided with a helical spline groove in the middle part of drive sleeve 102, this helical spline groove matches with the helical spline screw rod on semiaxis 103, and when semiaxis 103 rotates relative to drive sleeve 102, drive sleeve 102 can move linearly along the axis of semiaxis 103.Overrunning clutch 301 comprises outer race 305 and inner race 306, and inner race 306 is provided with interior spline, and the spline of drive sleeve 102 left end is connected with the interior spline of inner race 306 all the time, and outer race 305 is coaxially fixedly connected with wheel hub 201 by spline.So, when semiaxis 103 relativeatoeterahub 201 relatively rotates, cause also relatively rotating between drive sleeve 102 and semiaxis 103, just relative rotation motion can be changed into drive sleeve 102 to move horizontally along the axial direction of semiaxis 103, finally insert overrunning clutch 301 completely and contact spacing with wheel hub 201 axle head.The helical spline groove direction of the spline screw rod on semiaxis 103 and drive sleeve 102 endoporus is left-handed.
As shown in Figure 3, displacement pin 202 top is straight pin, top is hemisphere, be convenient to pierce cooperation with the radial hole of wheel hub 201 circle distribution, the larger cone of a cone bottom diameter in displacement pin 202 bottom, spring 204 is inserted in displacement pin 202 column part, and spring 204 lower end surface is supported on cone upper-end surface, and spring 204 upper-end surface leans on inner casing 203 inwall.The cone head of displacement pin 202 has a segment-shaped endoporus, and the inside press-fits embedding one steel ball, and is coated with lubricating grease, is played the effect of anti-attrition when displacement pin 202 moves along drive sleeve 102 conical surface by the spinning motion of its steel ball 205 in segment.Inner casing 203 circumferencial direction has round tube hole with displacement pin 202 corresponding part, and displacement pin 202 can be made to pass through, and meanwhile, one end that inner casing 203 right-hand member endoporus and semiaxis 103 radius are larger coordinates with the form of spline and is fixed together, and keeps geo-stationary between the two.In the outer surface cover of inner casing 203 is wheel hub 201, equally, wheel hub 201 is also having circular hole with corresponding place, displacement pin 202 top, and object is also in order to displacement pin 202 can be inserted, and wheel hub 201 and inner casing 203 and semiaxis 103 is linked together by displacement pin 202.Under vehicle stationary state, displacement pin 202 return under the action of the spring, its top is return in inner casing 203, throws off and contacts, realize the separation of above-mentioned part with wheel hub 201.
As shown in Figure 4, the internal surface of overrunning clutch 301 and outer surface are all splines, the left end portion outer surface of drive sleeve 102 is also spline, overrunning clutch 301 external splines and wheel hub 201 internal spline interference fit, overrunning clutch 301 internal spline and drive sleeve 102 left end external splines Spielpassung.Relative movement can be produced in the axial direction between overrunning clutch 301 and drive sleeve 102.
As shown in Figure 5, overrunning clutch 301 has inside and outside two external members, is outer race 305 and inner race 306 respectively.Can relatively rotate between two external members.Between two external members, uniform three wedge type spaces.In space, respectively be placed with a cylindrical roller 308, linked together by two springs 307 between each cylindrical roller 308 and coating part 305, spring 307 one end leans hole end surface in coating part 305 wedge type, and the other end leans in cylindrical roller 308 outer cylinder.When internal member 306 rotates relative to the direction that coating part 305 diminishes to space, the direction that can diminish to space with cylindrical roller 308 is moved, therefore, inside and outside can press tighter and tighter between external member 305 and cylindrical roller 308, produce great frictional force, therefore power can be sent to coating part 305 from internal member 306.Rotate as internal member 306 becomes large direction relative to coating part 305 to space, then internal member 306, can be more and more loosening between coating part 305 and cylindrical roller 308, therefore can not produce the transmission of power between inside and outside external member 305.By this structure, overrunning clutch 301 just reaches the object of one direction transferring power.
As shown in Figure 6, in another embodiment, described automobile-used automatic Free hub also comprises knuckle 105.Knuckle 105 is supported on knuckle 105 by a pair tapered roller bearing 303 with inner casing 203 and wheel hub 201.Meanwhile, inner casing 203 and wheel hub 201 upper bearing (metal) position are all overlapped and are had snap ring 302, in order to spacing to bearing 303.By six uniform studs 106, both location are fixed together between knuckle 105 and bearing housing 104, the right-hand member of bearing housing 104 contacts with bearing 303 inner ring, bearing 303 outer ring leans against and knuckle 105 endoporus between centers gives spacing, thus transmits lateral force suffered by wheel and radial force by bearing 303.Finally, wheel rim 304 is fixed on wheel hub 201 by 5 rim bolts 309 by wheel hub 201.
The working procedure 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 operating handle and transfer case combination is prepared to travel with 4 wheel driven, along with the increase of accelerator pedal aperture, driving force increases gradually and drives automobile by static, accelerates starting, and now semiaxis 103 obtains moment of torsion that automotive powerplant provides and starts rotation.For traditional time sharing automobile, because transfer case combines, semiaxis 103 obtains engine drive torque by the differential mechanism of this bridge; For four motorized wheels electric vehicle, the controlled output driving torque of this bridge two wheel motor.Owing to being coordinated by helical spline between semiaxis 103 and drive sleeve 102, drive sleeve 102 coordinates with spline again with between overrunning clutch 301, therefore after semiaxis 103 rotates, therefore the inner race 306 of overrunning clutch 301 is driven to rotate relative to the direction of outer race 305 to extruding cylindrical roller 308, thus overrunning clutch 301 is locked, by transmission of power to outer race 305, realize power transmission, then overrunning clutch 301 drives wheel hub 201 to rotate by external splines, namely drives tire 304 to start to rotate.Meanwhile, drive sleeve 102 is moved to the left along spline screw rod, the conical surface of drive sleeve 102 heads on displacement pin 202 in the vertical direction and moves upward, extrusion spring 204, along with drive sleeve 102 is moved to the left, displacement pin 202 finally puts in the circular hole of the radial equipartition of wheel hub 201, finally because drive sleeve 102 moves to after high order end contacts with wheel hub 201, conjugates the conical surface large footpath place that pin 202 is parked in drive sleeve 102.Now, semiaxis 103 passes to inner casing 203 by spline driving torque, and driving torque is passed to wheel hub 201 by displacement pin 202 again by inner casing 203.Namely driving torque passes to wheel hub 201 and wheel thereof by overrunning clutch drive part through semiaxis 103 together with displacement pin drive part two lines.Here, the wearing and tearing of cylindrical roller in overrunning clutch can be slowed down by overrunning clutch and the common transmitting torque of displacement pin two-part, ensure reliable transmission.Now, semiaxis 103, wheel hub 201, overrunning clutch 301, inner casing 203, drive sleeve 102 are the equal of integrally, together along with semiaxis 103 rotates.Now, automobile is 4 wheel driven state.
When acceleration mode automobile enter the middle high speed of a motor vehicle at the uniform velocity normal time travel time, now because between semiaxis 103 and wheel hub 201, rotating speed is identical, between the two without relatively rotating, also without relatively rotating between drive sleeve 102 and overrunning clutch 301.Now, displacement pin 202 press against the conical surface of drive sleeve 102 under the reseat pressure effect of spring 204, it is decomposed into the component of both direction along conical surface to the pressure of drive sleeve 102, one along conical surface, a vertical circular conical surface, component perpendicular to conical surface have push drive sleeve 102 move right reset trend, and this trend requires that drive sleeve 102 has relative to spline screw rod trend forward, when drive sleeve rotates forward, the direction extruding cylindrical roller 308 of the inner race 306 that can make again overrunning clutch 301 outer race 305 vis-a-vis, thus overrunning clutch 301 is locked again, still be in 4 wheel driven state.Therefore, when automobile moves forward with 4 wheel driven state, be no matter accelerate or at the uniform velocity state, automobile can keep 4 wheel driven state, effectively ensure that Riding Stability of Automobile.
When transfer case switches to two to drive gear, because semiaxis 103 there is no driving torque, and the wheel of this bridge driven rolls forward under the driving force effect of an other bridge, now overrunning clutch 301 recesses the angle of wedge because inside and outside external member 305 and 306 relatively rotates direction for making cylindrical roller 308 Compress Spring 307, therefore overrunning clutch 301 is thrown off and is not worked, now can without the dynamic angle of one side forwards under the axial thrust load effect of pressure being fixed on the Returnning spring 204 conjugated on pin 202 of constraint reaction with the drive sleeve 102 of overrunning clutch 301 inner race 306 spline joint, while move right, displacement pin 202 moves straight down along conical surface again, final displacement pin 202 exits from wheel hub 201, semiaxis 103 and wheel hub 201 depart from, now become two and drive state, semiaxis 103 transfixion, thus reduce the gear wear of differential mechanism or the electromagnetic consumable of wheel motor.Here, the effect that pin 202 plays reset is conjugated.When automobile itself from two drive principle when states starting travels with above similar, now because overrunning clutch 301 is thrown off, drive sleeve 102 and semiaxis 103 and this bridge master thereof subtract with differential mechanism by transfixion, thus save reactive loss.
When pilot control gear level is for reversing, if now transfer case is two drive shelves, wheel hub 201 rotates backward with vehicle body is driven under another bridge driving force effect, therefore, just have along extruding relatively rotating of cylindrical roller 308 direction between drive sleeve 102 and overrunning clutch 301, therefore, now overrunning clutch 301 also transferring power.Because overrunning clutch 301 drives drive sleeve 102 to rotate with spline engagement, therefore also relatively rotate between drive sleeve 102 and spline screw rod, therefore drive sleeve 102 is moved to the left along spline screw rod, equally, the conical surface of drive sleeve 102 again heads on displacement pin 202 in the vertical direction and moves upward, link together wheel hub 201 and semiaxis 103 synchronous rotary, now due to for traditional four-wheel driven car semiaxis and differential mechanism rotating, or for four motorized wheels electric car wheel limit rotor rotate, so time there is idle energy consumption.But because reverse travel is little operating mode, namely running time is very short, therefore accumulative idle energy consumption is little.
When pilot control gear level is for reversing, if when now transfer case still rests on the reversing of 4 wheel driven shelves, because semiaxis 103 obtains reverse direction actuation moment or motor reverse direction actuation moment that motor sends through speed changer, drive sleeve 102 is driven to rotate backward in advance, due to overrunning clutch 301 internal member 306 relative coating part 305 counterrotating connected with drive sleeve 102 external splines, now, overrunning clutch 301 cylindrical roller 308 Compress Spring 307 under the frictional force effect of internal member 306 moves to the direction exiting the angle of wedge, therefore, the disengagement of overrunning clutch 301 inner-outer sleeve does not work, now owing to there is no constraint reaction, drive sleeve 102 abuts against right side and rotates in company with semiaxis 103 synchronous backward, displacement pin 202 rests on drive sleeve 102 path place and does not play connection function, wheel hub 201 is connected with semiaxis 103 mechanical, driving torque cannot pass to this bridge wheel, 4 wheel driven pattern is inoperative in fact, automobile is still two drive traveling.Due to less demanding to automobile passability during reverse travel, so time little on automobile passability impact.For avoiding affecting driver impression, mechanical linkage which controls or control logic can be adopted to control to automatically switch to two when rolling-back of car travels and to drive pattern.
Although embodiment of the present invention are open as above, but it is not restricted to listed in specification and mode of execution utilization, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
