Abstract
An interlocking differential driver for wheel-type vehicle is composed of a differential mechanism consisting of external and internal differential units and two power distributors linked to wheels. Its advantages are no wheel skid, no power circulation and small size.
Description
The present invention is a kind of inter-locking differential driver, belongs to the wheeled vehicle transmission field.
Up to the present, automobile often adopts the mode that installs differential mechanism on propons or back axle additional to carry out transmission, and this type of automobile is easy to skid at the road of mire and can't cruising.And many bridges driving automobiles also can only solve the two-wheel drive problem of slip.Can not solve driving wheel equally when the condition of adhering to does not satisfy, the wheel-slip problem.When trackslipping inadequately as respectively having one side or diagonal angle wheel to adhere to before and after occurring, automobile just can't travel.In order to overcome wheel-slip, people have designed multiple differential lock, but they exist a common issue with, and promptly locked differential mechanism can be brought into play due tractive force, the turning of just can not leading of this car; If can lead turning, just can not on abominable muddy road, bring into play due tractive force, up to the shortcoming that can't travel.
For the problem that overcomes wheel-slip, the patent No. is: the patent of invention of ZL98100725.2 has proposed a solution, and it can overcome wheel-slip problem when abominable muddy road travels.But when good road surface is run at high speed, can only be with forerunner or rear-guard.The patent No. is: the utility model patent of ZL99208786.4 has proposed a kind of frequently interlocked universal differential driver; it has solved between centers differential and differential mechanism inter lock problem between wheel, but a sliding device of control, complex structure are equipped with in its middle part; volume is big, and is not suitable for car.
The objective of the invention is to be improved on this basis, a kind of designs simplification is provided, superior performance is applicable to the inter-locking differential driver of car, reduces volume, improves assembly performance.
Technological scheme: a kind of inter-locking differential driver, it mainly is to be made of differential mechanism, described differential mechanism links to each other with two differential gears, and draw with wheel on the diagonal from its outside and to link to each other, it is characterized in that: described transmission device also comprises two power distribution devices, described differential mechanism is that an outer differential and the interior differential by a shared bearing pin is sleeved on the central composite differential that constitutes together, and links to each other with wheel by described power distribution device.
The central composite differential that inter-locking differential driver of the present invention has adopted central suit differential to constitute, the structure that is connected with the power distribution device.Output semiaxis finish work separately outside, and separately the independence of conditioning each other, no matter make when that wheel loses driving force, four output semiaxis are because the combination of two differential mechanisms, can form new differential according to the wheel drive needs arbitrarily jointly, finish between driving, wheel and diagonal angle differential task.Make automobile safety when expressway travels turn to, not influenced by road conditions, between wheel, any differential in diagonal angle, thereby reached simplified structure, guarantee the purpose of superior function, and volume reduces greatly, assembly performance is improved.
Describe the present invention in detail below in conjunction with accompanying drawing:
Fig. 1, inter-locking differential driver embodiment one sectional view of the present invention;
Fig. 2, inter-locking differential driver embodiment one kind of drive structural representation of the present invention;
Fig. 3, inter-locking differential driver embodiment two sectional drawings of the present invention.
As shown in the figure, inter-locking differential driver of the present invention is to be made of the differential mechanism of two combinations and two power distribution devices, and wherein the power distribution device comprises power distribution driving gear 9 and power distribution driven gear 10; Two differential mechanisms comprise an outer differential and an interior differential; Inside and outside differential is sleeved on shared together bearing pin 2 and constitutes central composite differential 1, respectively there are two semiaxis at its two ends, one is solid semiaxis 3, another is a hollow half axle 4, wherein solid semiaxis 3 is connected with differential two-semiaxle gear 5 in the central authorities, hollow half axle 4 is after outer differential differential gear 6 is connected with central authorities, solid semiaxis 3 passes hollow half axle 4 and links to each other with wheel respectively with power distribution driven gear 10 by power distribution driving gear 9, main reducing gear driven gear 7 is contained on the shell 8 of central composite differential, drives central composite differential 1 and rotates.Support by steel ball 11 between the inside and outside differential, also support between outer differential of central authorities and the shell 8 by steel ball 11.
When skidding simultaneously as two wheels in diagonal angle of automobile or two wheels of homonymy, differential mechanism drives the diagonal angle wheel that it linked to each other in the central authorities, makes two non-slip wheel differentials, the driving automobile normal running.When the normal differential of automobile, it finishes between wheel, diagonal angle differential and interlocking.Unsettled as front right wheel, the right wheel spin of preceding hollow half axle gear drive, the preceding left wheel that solid semiaxis drives does not change, the differential differential gear does not change in the coupled central authorities, another differential gear of differential mechanism and a back solid differential gear rotation that links to each other drive the solid semiaxis driving wheel rotation in back in the central authorities.The solid semiaxis in back connects wheel and preceding right wheel homonymy, and car has at least the wheel support can be not unsettled in the same side, make automobile normal running.In like manner, even an automobile has three wheel-slips simultaneously, automobile still can cruising.
During automobile turning, the speed difference between front-wheel and rear-wheel spindle is satisfied by the synchronous differential of differential mechanism in differential mechanism, the central authorities outside the central authorities.All around differential is to finish differential by differential mechanism in the central authorities between the wheel of wheel.
Their power output is by hollow half axle and power distribution driving gear engagement power distribution driven gear by the hollow half axle gear; Differential two-semiaxle gear is adjacent in the central authorities two-semiaxle gear and solid semiaxis conspire to create an integral body, directly moment of torsion are defeated by the wheel at diagonal angle respectively by power distribution driving gear engagement power distribution driven gear or solid semiaxis.
The job order that realizes shaft space difference speed is: the center differential bearing pin--the central interior differential mechanism of the outer differential planetary gear of central authorities--the outer differential two-semiaxle gear of central authorities--.
Realize between wheel, the job order of diagonal angle differential is: center differential bearing pin---differential planetary gear in the central authorities---differential two-semiaxle gear---two hollow half axle gears---two hollow half axles---, two solid differential gears and two solid semiaxis in the central authorities.
In the middle part of this inter-locking differential driver vertically is installed at the bottom of the car, and be retractable in the car belly.This device does not use ransaxle, can make at the bottom of the car smoothly, reduces resistance of air and lift at the bottom of the car, improves the crack, ground, makes it have good passing ability and fuel economy.The while designs simplification, more reasonable, volume reduces, the vehicle that is particularly useful for running at high speed.
