Description
Technical field
The utility model belongs to vehicle wheel edge system technical field, and in particular to a kind of knuckle of vehicle, it is adaptable to solely
On the truck of the vertical central inflation/deflation of suspension band.
Background technology
Common truck knuckle assembly is only to realize carrying and turning function, but with China's automotive technology development and
The demand of special operation condition, the demand to parts and its function gradually increases, vehicle in the process of moving, hub reduction gear tooth
Wheel gear motion causes gear oil temperature to raise, air pressure increase in wheel hub oil pocket, can if gas can not be discharged in time
Cause oil sealing oil leak.Vehicle is during cross-country, because operating mode is more complicated, it is easy to occurs tire and loses gas phenomenon.
The inflatable and deflatable needs of existing vehicle tyre are carried out under vehicle stop state, and need specific inflation/deflation to set
It is standby, therefore, can not charge and discharge in time due to lacking inflation/deflation equipment when vehicle is in field and adverse circumstances need inflation/deflation
Gas, for armored vehicle, parking inflation/deflation is lost time, and significantly impacts the adaptability to changes of vehicle.
Utility model content
The purpose of this utility model is to provide a kind of knuckle of vehicle, realizes in vehicle travel process to vehicle wheel
Tire is inflated, and solves the technical problem that excessive gas is discharged in wheel hub oil pocket.
The technical solution of the utility model is that 2 airways, 2 airway bags are provided with a kind of knuckle of vehicle
First paragraph inflation road and deflation road are included, the entrance in first paragraph inflation road is located on the periphery of knuckle outer rim, first paragraph inflation road
Gas outlet be located at knuckle axle portion two bearings between, the entrance in deflation road is connected with lubricant reservoir in knuckle assembly,
The outlet in deflation road ensures that the outlet in deflation road is inclined upwardly on the periphery of knuckle outer rim, the outlet in deflation road with
Vent connection 5 is fixedly connected, and filtering breather plug is fixed with vent connection.
The beneficial effects of the utility model, knuckle of the present utility model realizes central charging-discharging function, will be fixed
Source of the gas is incorporated into the tire of motion, and cost is relatively low, while after proving ground experiment, working well, experimental stage does not go out
The problem of what incumbent gas leak of the oil leakage；Ensure gear oil will not be headed into tire in inflation；Realize in vehicle travel process
In vehicle tyre is inflated, it is ensured that continue to travel in vehicle, save the time, complete traveling operation；Wheel side is solved to subtract
Fast device gear gear motion causes gear oil temperature to raise, air pressure increase, caused oil sealing oil leak technical problem in wheel hub oil pocket；
The utility model knuckle discharges gas unnecessary in wheel hub oil pocket by air vent, it is ensured that the stable gas pressure in wheel hub cavity.

Embodiment
The technical solution of the utility model is described in further detail with reference to Figure of description.
As shown in Figures 1 to 5,2 airways, 2 airways are provided with a kind of knuckle of vehicle of the utility model
Road and deflation road are inflated including first paragraph, the entrance in first paragraph inflation road is inflation road entrance, and first paragraph inflates entering for road
Mouth is located on the periphery of knuckle outer rim, and the gas outlet in first paragraph inflation road is located between two bearings of knuckle axle portion.Put
Air flue is located on knuckle, and the entrance in deflation road is connected with lubricant reservoir in knuckle assembly, and the outlet in deflation road, which is located at, to be turned to
On the periphery for saving outer rim, and ensure that the outlet in deflation road is inclined upwardly, prevent lubricating oil from being spilt by deflation road.Deflation road goes out
Mouth is fixedly connected with vent connection 5, and filtering breather plug is fixed with vent connection 5.Deflation road is used to discharge because temperature is high,
The gas produced in lubricant reservoir.
As shown in figure 5, bushing 1 is set on the periphery of knuckle axle portion, and bushing 1 is located at two axles of knuckle axle portion
Between holding, two O-ring seals 3 are provided between the inner circumferential and knuckle axle portion periphery mating surface of bushing 1.Two oil gas envelopes 2
The inner side of two bearings of knuckle axle portion is fitted in respectively.Two oil gas seal 2 medial surface, the periphery of bushing 1 and wheel hub 6
Inner circumferential collectively forms inflation airtight chamber.Inflate road include first paragraph inflate road and second segment inflation road, first paragraph inflation road and
Second segment inflates road Nature Link.Second segment inflation road is located on wheel hub 6, and between two bearings in the middle part of knuckle, the
The entrance in two sections of inflation roads is connected with inflation airtight chamber, and the outlet in second segment inflation road is connected with inflation elbow 4, is inflated curved
First 4 are connected by check valve and pipeline with tire inflator nozzle.
Because vehicle is in daily traveling, gear oil is present in knuckle assembly simultaneously with the pressure-air for tyre inflating
In, by gear oil top to inside tires during to prevent that vehicle is inflated to tire, so as to cause to take turns side assembly caused by oil starvation
Damage, the utility model makes vehicle ensure Oil-gas Separation when inflatable and deflatable by bushing 1, O-ring seal 3 and oil gas envelope 2.
