Description
Technical field
The present invention is the improvement about differential mechanism lubricating system, particularly relates to the circulation cooling lubrication device of Horizontal spiral discharging centrifuge differential mechanism.
Background technology
Differential mechanism exists output speed two kinds different, although the speed values difference of both output speeds is less, but both high-speed motions, therefore substantial amounts of heat can be produced, prior art is to utilize splash lubrication mode to take away heat energy, and effect is poor, causes that differential mechanism is overheated, make the part in differential mechanism kill, form parking accident.
China Patent Publication No. is CN1470781, discloses a kind of inter-axle differential assembly with lubricating pump. Pump is installed between differential mechanism input and output shaft, by being connected with output shaft or in hole that all-in-one-piece side gear is determined. Pump has housing, housing to have first and second mouthfuls and arcuate groove at radially-outer surface. Pin is radially inwardly extending from side gear and in insertion groove. Groove and pin coordinate makes whole pump energy opposite side pinion rotation, and therefore changes the position of two mouths. So, this assembly provides only the pump of the Double-directional rotary of supply lubricant when relatively rotating between differential mechanism input and output shaft, it solves the problem of splash lubrication by setting up lubricating pump in differential mechanism, and the high temperature grease in running cannot be made to discharge and recycle.
China Patent Publication No. is CN201568559U, discloses a kind of differential lubricating device, and including differential mechanism, differential mechanism axle housing and fastening bolt, this device is provided with oil skipper on differential mechanism axle housing. This differential lubricating device, under vehicle bridge operating conditions, it is ensured that in axle housing, lubricating oil fully stirs splashing, contributes to the lubrication of differential assembly and the sufficient lubrication of drive bevel gear bearing. Will not because of lack of lubrication or to lubricate the assembly caused not in place overheated, mechanism sinters. Reduce the service life of assembly. Its principle is also adopt to set up oil skipper, utilizes splash lubrication, though lubricant effect is improved, but effect inconspicuous.
China Patent Publication No. is CN101881331A, disclose a kind of auxiliary lubricating system of differential, including the fixing bolt of lubricating oil pipe, locking plate and locking plate, wherein lubricating oil pipe is arranged on oil duct place reserved on converter cover, one end of locking plate is by the fixing locked with bolts of locking plate to converter cover, the other end is pressed on lubricating oil pipe thus fixing lubricating oil pipe, and lubricating oil pipe passes through aperture thereon, and differential mechanism central gear position is carried out enforced lubricating. Present configuration is compact and simple, it is simple to manufacturing and assembling, reliability is high, thus solving the difficult problem that gear oil mass automatic transmission differential mechanism few, lubricating difficulties lubricates, slow down the abrasion of differential gear, improve differential mechanism service life, its structure is reserved oil duct in housing, insert lubricating oil pipe and carry out enforced lubricating, although the problem overcoming splash lubrication weak effect, but its structure is complex, need to separately set up parts, and lubricating oil can not be circulated utilization, have much room for improvement.
Summary of the invention
The present invention solves above-mentioned technical problem, it is provided that one effectively overcomes differential mechanism excessive velocities, inner body temperature rise is too high causes that part kills formation parking accident, high lubricating effect, the differential lubricating device of the improvement of lubrication capable of circulation.
The present invention is directed to above-mentioned technical problem, provide techniques below scheme: the differential lubricating device of a kind of improvement, including the connection axle for placing restrictions on moment of torsion that differential mechanism is connected with differential mechanism, it is characterized in that described connection axle is hollow axle, connect axle one end connected with differential, one end connects swivel joint, connect in axle and be provided with hollow pipe, hollow pipe one end connection swivel joint, swivel joint connects oil pump, hollow gear shaft in hollow pipe other end connection differential mechanism, hollow gear shaft offers single or multiple oil transportation hole.
As a further improvement on the present invention, the described axle that connects has oblique or straight single or multiple circulation oilholes on the axial wall stretching into differential mechanism one end, the connection of described circulation oilhole connects the centre bore of axle, and connecting of swivel joint one end has, on axial wall, the oil leak hole connected with centre bore. Arranged by this kind, utilize siphon principle to be sucked by high temperature lubricating liquid and connect discharge cooling in centre bore in axle.
Preferred as the present invention, described circulation oilhole be set to lead to the connection level of axle centre bore, vertical four, it is in communication that each hole all separately offers an inclined hole, and described level, vertical four recycle oil bore ends seal. Arrange centripetal pump by this kind to make full use of the kinetic energy of liquid and change into pressure energy. The process that liquid kinetic energy changes into pressure energy carries out in the runner of centripetal pump, it is full of oil when differential mechanism is internal, the high speed rotating of differential mechanism drives the high speed rotating of oil, diagram oil is tangentially flow at high speed in the outer rim of centripetal pump, this kind of perforate direction in order that can reduce as far as possible liquid enter runner time produce resistance so that it is can better carry out energy conversion. Kinetic energy is converted to pressure energy: differential mechanism is internal when being full of oil, and internal pressure becomes big, forces liquid to be walked toward the place of low pressure, and after liquid tangentially enters runner, liquid moment is full of inside centripetal pump, and owing to inner passage is narrow and small, natural pressure just becomes big.
The object of the invention realizes, and is mainly improved by, the mode utilizing splash lubrication mode to take away heat energy, changing forced feed lubrication circulating cooling mode into. Specifically, the present invention changes former for the differential mechanism solid connection axle being connected with for placing restrictions on moment of torsion as hollow axle into, installs a hollow pipe, enter circulation cooling lubrication in the middle of hollow pipe in the middle of hollow axle, hollow pipe one end is connected with swivel joint, utilizes pump to be circulated the feed liquor work of coolant.Cooling-lubricant arrives inside differential mechanism by hollow pipe, the surface that the oblique or straight single or multiple apertures on hollow gear shaft are dispersed to differential mechanism moving parts under the drive of differential mechanism slow-speed shaft is utilized to play lubrication and the effect of cooling moving parts, lubricating fluid through lubrication and the relatively-high temperature of cooling utilizes the high-speed motion of differential mechanism shell, by changing into and the axial wall of hollow axle is opened oblique or straight single or multiple apertures utilize siphon principle quickly to discharge high-temp liquid placing restrictions on the solid shafting that moment of torsion connects, high-temp liquid, through supercooling, is circulated again through pump.
Beneficial effects of the present invention: the present invention is by making hollow axle at connection axle, and oil pipe is within it set, splash lubrication in differential mechanism is changed into forced feed lubrication, and on the axial wall stretching into differential mechanism one end, have oblique or straight single or multiple circulation oilholes connecting axle, utilize siphon principle circulating cooling, substantially increasing cooling effectiveness, effectively overcome differential mechanism excessive velocities, inner body temperature rise is too high causes that formation parking accident killed by part.
