Description
Technical field
The present invention relates to automobile differential, more particularly to a kind of engagement type automobile differential.
Background technology
Differential mechanism is that one kind can make rotary motion reach two axles from an axle, and makes the latter each other can be with different rotating speeds
The differential attachment of rotation.It is August in 2013 21 days, entitled " electricity in Chinese Patent Application No. 2011800533570, publication date
The automobile differential of an existing structure, automobile differential bag are disclosed in the patent document of the locking differential of gas triggering "
Include planetary wheel carrier and two axle shaft gears in planetary wheel carrier.The left and right semiaxis of automobile when using（When for center differential
Shi Zewei antero posterior axis）One is connected to after being stretched into through semiaxis mounting hole in planetary wheel carrier with two axle shaft gears correspondingly
Rise, driven and rotated by axle shaft gear., it is necessary to inject lubricating oil to be lubricated to prolong differential mechanism during use
Long-life.
Existing difference device has the following disadvantages：When automobile is travelled on bad road, handling capacity can be had a strong impact on.For example
When a driving wheel of automobile is absorbed in muddy road surface, although another driving wheel is in good road surface, before automobile is but tended not to
Enter（It is commonly called as skidding）.Now the driving wheel original place on muddy road surface is trackslipped, the but transfixion of the wheel in good road surface.This
It is smaller because of the adhesive force between the wheel on muddy road surface and road surface, road surface can only act on smaller by this wheel to semiaxis
The moment of reaction, therefore differential mechanism distribute to this wheel torque it is also smaller, although attached between another driving wheel and good road surface
Put forth effort larger, but the characteristics of because of mean allocation torque, this driving wheel is also assigned to the torque with slipping drive wheel equivalent,
So that driving force is not enough to overcome running resistance, automobile can not advance, and power is then consumed on slipping drive wheel.Now increase
Throttle can not only make automobile advance, and fuel oil is wasted on the contrary, accelerate component wear, especially aggravate tire wear.
The content of the invention
Two semiaxis synchronous axial systems can be made when being more than setting value the invention provides a kind of differential when two semiaxis
Engagement type automobile differential, asking for handling capacity can be had a strong impact on when automobile is travelled on bad road by solving existing differential mechanism
Topic.
Above technical problem is solved by following technical proposal：A kind of engagement type automobile differential, including planetary gear

To the contract of planetary gear 6, seal head 83 shrink and so that oil-out 81 open and cause the energy storage of the first spring 84.
Referring to Fig. 7, also piston 86 is driven to be moved towards oil pocket 852 by connecting rod 862 when seal head 83 shrinks, oil pocket 852
Interior pressure rise cause check valve 861 close and the lubricating oil in oil pocket 852 through oil duct 87 flow to oil-out 81 and from fuel-displaced
Flowed out in mouth 81 and realize lubrication.
When axle shaft gear loses the squeezing action to seal head 83, seal head 83 is outer in the presence of the first spring 84 moves
And seal up oil-out 81, drive piston 86 to be moved towards air cavity 851 by connecting rod 862 when seal head 83 stretches out, oil pocket 852
Interior pressure declines and the pressure in air cavity 851 rises so that check valve 861 is opened, unnecessary oil in air and fueling cavity 56
Oil pocket 852 is flowed to through gas supplementing opening 82, air flue 88 and check valve 861 so that the pressure in oil pocket 852 can maintain same gear
Air pressure in outside is equal, can squeeze out lubricating oil when being moved so as to piston 86 towards oil pocket 852 next time.
Therefore lubricating oil need not be added in planetary wheel carrier in the present embodiment, realizes the dry-type working of connecting plate, rubs
Wipe good reliability during adhesive.
Embodiment five, the difference of be the same as Example four is：
Referring to Fig. 9, the interior bar 51 of circle is equipped with planet wheel spindle 5.Interior bar 51 is tubular structure.Planet wheel spindle 5 it is interior
Surface is provided with interior frictional layer 52.Interior bar 51 includes left bar 511 and right bar 512.The outer peripheral face of left bar 511 and right bar 512 is designed with
External friction layer 513.Circumference of the external friction layer 513 along interior bar 51 is covered with interior bar 51.The left end of left bar 511 passes through left energy-absorbing spring 53
Linked together with planet wheel spindle 5.The right side of left bar 511 is provided with some first commutating tooths 514 circumferentially distributed along left bar.It is right
The right-hand member of bar 512 is linked together by right energy-absorbing spring 54 with planet wheel spindle 5.The left side of right bar 512 is provided with some along the right side
The second circumferentially distributed commutating tooth 515 of bar.First commutating tooth 514 and the second commutating tooth 515 mesh together.Left bar 511 and the right side
Bar 512 is also all abutted together with interior frictional layer 52 by external friction layer 513 and is rotatably connected together with planet wheel spindle 5.
The rubbing agent of liquid is filled with planet wheel spindle 5.
When planet wheel spindle 5 produces distortion, planet wheel spindle 5 can produce relative rotation relative to interior bar 51, in motion process
External friction layer 513 and interior frictional layer 52 rub and consume energy and play a part of preventing twisting.If the torsion of planet wheel spindle 5
Square and when result in interior bar 51 and also producing twisting together, now left bar 511 and right bar 512 can be in the first commutating tooths 514 and second
Axially spaced under the guide effect of commutating tooth 515, separation process is not only able to so that external friction layer 513 is with interior frictional layer 52
Produce friction and energy-absorbing, left energy-absorbing spring 53 and right energy-absorbing spring 54 can also be promoted to deform and energy-absorbing, play energy-absorbing and prevent
The effect produced is reversed, so as to realize the distortion resistance for improving planet wheel spindle.And right energy-absorbing spring 54 and left energy-absorbing spring 53
It can also play a part of repairing planet wheel spindle 5.
