Specific embodiments
With reference to accompanying drawing, two output degrees of freedom that the invention is characterized in differential mechanism are input to two groups of planetary gear set that mutually lock by row sun gear axle, then realize that by controlling two planetary gear set regulating two exports freely speed discrepancy, this transfers the constant velocity driving shaft of poor differential mechanism and worm screw 1 directly to drive constant speed driving worm gear 2, and constant speed driving worm gear 2 and differential gear frame 3 are as a whole; Differential pinion gear 4, right axle shaft umbrella gear 5 and left half axle umbrella gear 6 are installed in differential gear frame 3 interior formation differential mechanisms; Left half axle umbrella gear 6 and left half axle the first driving gear 8 and left half axle transfer poor sun wheel 16 coaxial left half axle the first driving gears 8 by meshing and be transferred to left half axle 13 with left half axle the second driving gear 9, left half axle transmission shaft 10 and left half axle the 3rd driving cog 11 and left half axle the 4th driving cog 12; Right axle shaft umbrella gear 5 and right axle shaft transfer poor sun wheel 17 coaxial lines to form right axle shaft 7; Left half axle transfers poor sun wheel 16 and right axle shaft to transfer poor sun wheel 17 to transfer poor planet wheel 18 and right axle shaft to transfer poor planet wheel 19 engagements with left half axle respectively, left half axle transfers difference planet wheel 18 and right axle shaft to transfer poor planet wheel 19 common row gear racks 20, and the poor planet wheel 18 of left half axle accent and the poor planet wheel 19 of right axle shaft accent transfer external toothing 21 in the difference, right axle shaft to transfer external toothing 22 interior engagements in the difference in periphery and left half axle respectively; Left half axle is transferred external toothing 22 common and accent difference bevel gear 24 outer gearings in poor interior external toothing 21 and the right axle shaft accent difference; Rotating speed is transferred deviation shaft 23 directly to drive and is transferred poor bevel gear 24.
Working principle of the present invention is as follows:
This is transferred poor differential mechanism to drive constant speed by constant velocity driving shaft and worm screw 1 and drives worm gear 2, driving differential gear frame 3 and planetary pinion 4, right axle shaft umbrella gear 5 and left half axle umbrella gear 6 rotates, driving power is outputed to respectively left half axle 13 and right axle shaft 7, and wherein the rotation of left half axle 13 need to be passed through left half axle the first driving gear 8, left half axle the second driving gear 9, left half axle transmission shaft 10, left half axle the 3rd driving cog 11 and left half axle the 4th driving cog 12 and be transferred to left half axle 13.Transfer poor sun wheel 16 and right axle shaft to transfer poor sun wheel 17 with the coaxial left half axle of left half axle 13, right axle shaft 7 respectively in the transmittance process, by the left half axle of common row gear rack 20 transfer poor planet wheel 18, right axle shaft transfer poor planet wheel 19 be engaged in left half axle transfer poor in external toothing 21, right axle shaft transfer poor in external toothing 22; Left half axle transfer poor in external toothing 21, right axle shaft transfer poor in the locking of external toothing 22 modulated poor bevel gears 24, can only be static or wait oppositely speed rotation.Namely when transferring poor bevel gear 24 static, left half axle 13 and right axle shaft 7 are subject to the restriction of two groups of synchronous planetary gear set, can not produce speed discrepancy, can only constant speed rotate.When rotating speed is transferred deviation shaft 23 to drive to transfer poor bevel gears 24 to rotate with two groups of planetary gear set of constant speed reverse direction actuation, then with equal and opposite in direction, the rotation of switched in opposite has been added on left half axle 13 and the right axle shaft 7, has realized that difference is controlled by the left and right half differential of transferring poor bevel gear 24 rotating speeds and rotates.Constant speed and differential drive in this differential mechanism have independence, and two kinds of driving moments and rotating speed all can not influence each other and disturb.
Work characteristics and Applicable scope:
Drive to rotate by transferring poor differential mechanism constant speed to decompose constant speed, constant speed has oppositely been decomposed differential and is driven and rotate simultaneously, and constant speed and differential drive in the differential mechanism have independence and additivity, and two kinds of driving moments and rotating speed all can not influence each other and disturb.Realized that accurately controlled constant speed is rotated distribution and differential rotates distribution.Replenish open differential and freely decomposed output driving rotation, can not decompose the poor characteristics of given rotating speed.Be applicable to constant speed and drive the mechanism that adjusts at any time speed discrepancy or phase difference simultaneously.Avoided independent two driving power equivalently not work and the unmanageable problem of difference.
