Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model Novel electric drive axle Multicarity sealing device.
Detailed description of the invention
All features disclosed in this specification, or disclosed all methods or during step, except mutually exclusive
Feature and/or step beyond, all can combine by any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), unless chatted especially
State, all can be by other equivalences or there is the alternative features of similar purpose replaced.I.e., unless specifically stated otherwise, each feature is only
It it is an example in a series of equivalence or similar characteristics.
As it is shown in figure 1, the better embodiment of this utility model Novel electric drive axle Multicarity sealing device includes driving
Axle housing body 1, described Driving axle housing 1 is for the installation protection of driver part；The water cavity 2 being arranged on housing 1, described water cavity 2
The confined space formed by sealing ring 5 and housing 1 by the water channel 20 being arranged on housing 1 is constituted；It is arranged on the gas on housing 1
Chamber 3, described air cavity 3 is made up of the confined space formed between the motor 9 being arranged on housing 1 and housing 1；It is arranged on housing 1
On oil pocket 4, space that lubricating oil circulates is deposited and guaranteed to described oil pocket 4 by oil sealing 6 and housing 1 by housing 1 superjacent air space
The confined space formed is constituted；Wherein, for preventing the water in water cavity 2 from revealing to motor 9 and be arranged on the driving in housing 1 time
Parts produce impact, are positioned at sealing ring 5 top position and are provided with dredging flow groove 10, be positioned at earial drainage in described housing 1 in described housing 1
On the left of groove 10, top position is provided with air inlet 7, is positioned at top position on the right side of dredging flow groove 10 and is provided with discharge orifice 11 in described housing 1.
When cooling down water and occurring to reveal, described air inlet 7 enter the gas of housing 1 produce water that air pressure makes water channel 20 reveal can be from
Discharge orifice 11 discharges housing 1.
In order to ensure cooling water can uniformly, effectively play cooling effect, it is achieved water circulates, and described water channel 20 is by many
Individual water is every 8 interlaced formation.Water is to realize the water conservancy diversion to cooling water and obstruct every the effect of 8, effectively realizes the stream of cooling water
Through speed controlling, preventing cooling down sometimes fast and sometimes slow produce cooling effect of water affects.
In order to the cooling even velocity of flow of water being effectively ensured and housing 1 being played cooling effect uniform, effective, described water every
8 use many bar shapeds and with between the housing of cooling water channel both sides, link the interlaced distribution of muscle (not shown).Water is every 8
Effect is so that cooling water flows to the other end according to given circulation canal from one end, and water every 8 use many bar shapeds and be positioned at
The mode of the link interlaced distribution of muscle (not shown) between the housing of cooling water channel both sides is formed, and is present to ensure that cooling water
Can uniformly, effectively flow through all sites of whole housing 1, it is ensured that housing 1 uniformly cools down, be unlikely to make owing to inhomogeneous cooling is even
Housing 1 temperature difference is become to crack the most greatly.
During cooling water circulating in water channel 20, prevent cooling down water and overflow housing 1, described water every
Cross-sectional area between bottom 8 lower surfaces and water channel 20 and water inlet area equation.So, both can guarantee that the recycle stream of cooling water
Logical, can ensure that again cooling water does not spills over housing 1.
The purpose of oil sealing 6 is present to ensure that lubricating oil flows in given spatial dimension and corresponding component is played lubrication
Effect, but, its sealing property is even more important by the selection of oil sealing 6 material, and in this utility model, described oil sealing 6 is poly-
Urethane material is made.Polyurethane material is a kind of emerging high-molecular organic material, has performance adjustable extent width, adaptability
By force, anti-wear performance is good, and mechanical strength is big, and adhesive property is good, and good springiness, to have excellent restoration, dynamic juncture good, low temperature
Flexible, good weatherability, the advantages such as oil resistivity is good, resistance to biological aging；Be applicable to furniture, household electrical appliance, building industry, communications with
And the insulation of industry etc., anti-skidding, seal, the multiple environment such as bonding.
In order to preferably play waterproof, impermeable effect, described sealing ring 5 uses silastic material to make.For cold
But, for water, mainly occur overflowing housing 1 upper surface when revealing, be easily accessible housing 1 internal, to the oil pocket within housing 1
4, the miscellaneous part of air cavity 3 and inside impacts, therefore, in order to prevent cooling water from when leakage, this situation occurring, if
Put the sealing ring 5 on housing 1 and can realize this function, but, preferably play waterproof, impermeable effect, make
For having the silicone rubber of preferable thermostability, electrical property, hydrophobicity, moisture resistance, lubricity and breathability, can well be real
Now this function.
In order to preferably play leakage-preventing effect, described dredging flow groove 10 is annular dredging flow groove 10.Annular dredging flow groove 10 exists
All can play the effect of earial drainage in whole housing 1 annular space, prevent water from assembling, earial drainage not in time, to housing 1 internal part
Produce impact.
This utility model Novel electric drive axle Multicarity sealing device, by being respectively provided with oil sealing 6, sealing in housing 1
Circle 5 and air inlet 7, be effectively isolated cooling water, lubricating oil and gas, i.e. ensure that each chamber reliable operation, the most effectively prevent cold
But water enters oil pocket 4 and air cavity 3 when revealing, and causes operation irregularity.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
