The course of work of the present invention is summarized as follows:
1st, vehicle straight-line travelling in good road surface
During straight-line travelling, the power that vehicle motor is passed over passes to the driving gear of main reducing gear through flange 29, The driving gear of main reducing gear drives differential casing 5 to rotate by the driven gear of main reducing gear, and differential casing 5 passes through Left and right planetary gear 8,9 drives left and right half gear 6,7 synchronized with differential casing 5 with the revolution of differential casing 5 respectively Rotation, left and right planetary gear 8,9 are not relatively rotated, left and right half gear 6,7 respectively by spline driving left and right half 3, 4 synchronous axial system, and then vehicle straight-line travelling in good road surface is driven, without differential between two trailing wheels of vehicle.
2nd, turn inside diameter
During turn inside diameter is travelled, the speed of outboard wheels is more than the rotating speed of inboard wheel, and by taking left-hand rotation as an example, vehicle passes through The power transmission of left and right half 3,4, the rotating speed of the right axle shaft gear 7 of automobile is more than the rotating speed of differential casing 5, now, with the right side Three right planetary gears 9 that axle shaft gear 7 is engaged occur reverse rotation with differential casing 5 while revolve round the sun, so drive and Positive rotation is produced while three left planetary gears 8 that three right planetary gears 9 are meshed are revolved round the sun with differential casing 5, is made The rotating speed of the left half axle gear 6 engaged with three left planetary gears 8 is less than the rotating speed of differential casing 5, and then makes left half axle 3 Rotating speed is smoothly turned less than the rotating speed of right axle shaft 4, vehicle;The turning principle of right-hand bend is identical with left-hand bend principle.
3rd, automobile ice and snow, miriness, the complex road surface such as wet and slippery, uneven traveling
In complex road surface such as ice and snow, miriness, the road traveling such as wet and slippery, uneven, the present invention has the sliding effect of limit to vehicle, with As a example by skidding occurs in the right wheel of vehicle rear-side, the rotating speed of right axle shaft 4 and right axle shaft gear 7 is higher than the rotating speed of differential casing 5, Three right planetary gears 9 being meshed with right axle shaft gear 7 are produced reverse rotation and drive three left planetary gears 8 positive certainly Turn, left and right planetary gear 8,9 is helical gear, and the pressure angle of left and right planetary gear 8,9 forces left lateral in engagement process Star gear 8 presses to its in the hole wall, forces right planetary gear 9 to press to its in the hole wall;The engagement of left and right planetary gear 8,9 is produced very Big axial force, makes the end face of left and right planetary gear 8,9 be respectively pressed against left end cap 10, right terminal pad 11.2, makes differential casing Very big internal friction being produced in 5, and then reducing the torque for being delivered to right axle shaft 4, the torque for being delivered to left half axle 3 increases, I.e. torque is automatically transferred on left half axle 3, limits right wheel-slip, is helped vehicle to get rid of poverty, and then is improved on vehicle complex road surface Safety traffic performance;The principle of getting rid of poverty that left wheel skids is identical with the principle of getting rid of poverty of right wheel.
The moment of torsion that side trailing wheel hanging or thorough slip condition occurs and shifts automatically in vehicle travel process can not make car When getting rid of poverty, the speed discrepancy of both sides wheel reaches certain value(120r/min), the locking trigger mechanism of differential mechanism worked immediately, with As a example by right wheel thoroughly loses adhesive force, during right wheel spin, right axle shaft 4 dallies, and left half axle 3 and left half axle gear 6 are with left car Wheel transfixion, the rotating speed of right axle shaft gear 7 are the twice of 5 rotating speed of differential casing, cam ring 13, external cam 14 rotating speed equal For the twice of differential casing 5, drive of the gear shaft 19 in the external cam 14 being engaged with is centrifuged around what differential casing 5 revolved round the sun There is high-speed reverse rotation under dynamic, one of them in first, second centrifugal-block 22,23 overcomes first under the influence of centrifugal force The torsion of torsion spring 24 outwards throws certain angle away, now first, second centrifugal-block, 22,23 groove of one of them with get rid of block 26 Locking is supported and is interlockingly connected, and triggers the latch functions of vehicle;Gear shaft 19 is centrifuged after latch functions triggering and stops rotation, and then drive External cam 14 is rotated at the same speed with differential casing 5, and external cam 14 is moved right along the lead of screw with 13 counterface of cam ring Dynamic, friction plate assembly is pressed on right end cap 12, the first friction plate 16 is reached unanimity with the rotating speed of the second friction plate 17, with the The rotating speed of the right axle shaft gear 7 of the engagement of one friction plate 16 and the end cap 12 matched with the second friction plate 17 is gradually synchronous, makes the right side Planetary gear 9 and left planetary gear 8 stop rotation, and left half axle gear 6 starts to rotate and makes the rotating speed of left half axle 3 gradually with the right side partly The rotating speed of axle 4 reaches unanimity, and is input into the moment of torsion inside back axle and is all delivered to 3 side of left half axle, so that vehicle is got rid of poverty.
Left wheel thoroughly loses the principle of getting rid of poverty of adhesive force:When left wheel is hanging or thoroughly skids, left half axle 3 dallies, right Semiaxis 4 is motionless with right wheel stationary, and right axle shaft gear 7, cam ring 13, the equal transfixion of external cam 14, differential casing 5 are being led Being rotated by for decelerator driven gear, is centrifuged around 14 high speed of external cam while gear shaft 19 is revolved round the sun with differential casing 5 Positive rotation, another in first, second centrifugal-block 22,23 outwards throw certain angle away under the influence of centrifugal force, make First, 22,23 groove of another of the second centrifugal-block is supported with the locking for getting rid of block 26 and is interlocked, and triggers the locking effect of vehicle, Now centrifugation gear shaft 19 stops rotation and simultaneously drives external cam 14 to rotate with differential casing 5, external cam 14 along with cam ring The lead of screw of 13 faying faces moves right, and friction plate assembly is pressed on right end cap 12, and the first friction plate 16 is rubbed with second 17 rotating speed of pad reaches unanimity, the right axle shaft gear 7 engaged with the first friction plate 16 and the right side that matches with the second friction plate 17 The rotating speed of end cap 12 is gradually synchronous, and the now torque on differential casing 5 drives right axle shaft tooth by the transmission of friction plate assembly Wheel 7 drives right axle shaft 4 to rotate, and so that the rotating speed of right axle shaft 4 and the rotating speed of left half axle 3 is reached unanimity, and all moments of torsion of back axle are complete Portion passes to right axle shaft 4, and then so that vehicle is got rid of poverty.
After vehicle rolls skid road surface away from, skidding side wheel recovers the minibreak of adhesive force moment and causes original skidding The rotating speed of side wheel this in a flash can be less than the rotating speed of opposite wheel, the centrifugation gear shaft 19 for now engaging with external cam 14 can produce The life rotation contrary with original high speed sense of rotation, at this moment supported the centrifugal-block being interlocked originally due to certainly with the locking for getting rid of block 26 Turn direction change can depart from locking support, so that centrifugation gear shaft 19 is recovered to free rotary state, and then make left and right half 3rd, 4 released state is in.Or locking rear vehicle is to the direction tip-tap direction of original skidding side wheel, such as originally due to left side Wheel-slip dallies and locking, and now tip-tap direction causes right side wheels rotating speed more than left side wheel rotating speed to vehicle to the left, The effect of unblock can be played.After unblock, external cam 14 is set back under the left and right of Corrugation pad elastic force to the left, does not recompress friction Piece component.
For ensureing vehicle safe driving, set and 30km/h is less than when speed(Thousand ms/hour), and two rear wheels of vehicle Speed discrepancy be more than 120r/min(Rev/min)When, the latch functions of vehicle could be touched.The elastic force of the first torsion spring 24 is set as a left side The speed discrepancy of right two trailing wheels is 120r/min(Rev/min)When first, second centrifugal-block 22,23 in one of them can just gram Take the first torsion spring elastic force outwards throw away and make its groove touch get rid of block 26 locking support on when size;Second torsion spring 28 Elastic force be set as getting rid of block 26 when speed is for 30km/h and the elastic force of the second torsion spring can just be overcome outwards to throw certain angle away make Centrifugal-block 22,23 enables and overcomes the elastic force of the first torsion spring outwards to throw its groove away and can not touch to get rid of the locking of block 26 and prop up Size when in support.When speed is more than 30km/h, get rid of block 26 overcome under the influence of centrifugal force the torsion of the second torsion spring 28 to Throw outward certain angle away, and then be prevented effectively from the groove of first, second centrifugal-block 22,23 and get rid of the locking of block 26 and support and interlock Close, prevent from triggering the latch functions of vehicle.
In describing the invention, it should be noted that term "front", "rear", "left", "right", " vertical ", " level ", The orientation of instruction such as " interior ", " outward " or position relationship are based on orientation shown in the drawings or position relationship, are for only for ease of and retouch State the present invention and simplify description, rather than indicate or imply that the device of indication or element must be with specific orientation, with specific Azimuth configuration and operation, be therefore not considered as limiting the invention.
