Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The hub unit of a kind of inner ring and ring flange integral structure referring to FIG. 1-2, including wheel hub 1,1 side of wheel hub
Top be fixedly installed with standing screw 2, the number of standing screw 2 is set as five groups, and during five groups of standing screws 2 with wheel hub 1 are
The heart circularizes array arrangement, the restriction of number and position for standing screw 2, improves the stabilization for being in connection automobile tire
Property, the safety when hub unit uses is improved, the side of 1 outer wall of wheel hub is clamped by the inner cavity of steel ball 3 and flange 4,
The surface hardness of steel ball 3 is quenched to HRC500, and the surface roughness of steel ball 3 is less than Ra1.6 μm, the restriction for steel ball 3,
It avoiding in the long-term use process, the surface of steel ball 3 is corroded the problem of wearing, the service life of the device is improved,
The middle part of 4 side of flange is fixedly connected with the side of support plate 5, the fixed company in the top of support plate 5 and the bottom end of grease-box 6
It connecing, the inner wall of grease-box 6 and the outer wall pivot bush unit of piston 7, the side of piston 7 are fixedly connected with one end of compressed spring 8,
The other end of compressed spring 8 is fixedly connected with the side of 6 inner cavity of grease-box, and the side of piston 7 and one end of constrictor 9 are fixed
Connection, constrictor 9 stretch out 6 outside side of grease-box length and compressed spring 8 initial length with it is another greater than piston 7
Distance of the side to the 6 inner cavity other side of grease-box, the limit of the length and 8 initial length of compressed spring stretched out for constrictor 9
It is fixed, the problem of lubrication in grease-box 6 during use cannot be extruded completely is avoided, the benefit of lubricating oil is improved
Through compressed spring 8 and the side outside grease-box 6 and one with connecting plate 10 is extended to the other end of rate, constrictor 9
Side is fixedly connected, and the side on 6 top of grease-box is fixedly installed with priming valve 11, the other side and oil pipe outside grease-box 6
12 one end pivot bush unit, the other end of oil pipe 12 run through the middle part 4 of flange and extend to the inside of wheel hub 1 and pass through tee tube
13 are fixedly connected with the side of two movable oil valves 14 respectively, the inner wall of movable oil valve 14 and the outer wall movable sleeve of motion stops 15
It connects, the bottom end of motion stops 15 is fixedly connected with one end of movable spring 16, less than two movable bullets of elastic strength of compressed spring 8
The sum of the elastic strength of spring 16, wheel hub 1 is produced when the maximum flexibility intensity of movable spring 16 is less than the automobile maximum travelling speed
Raw centrifugal force, the restriction for compressed spring 8 and the elastic strength of movable spring 16 avoid the process in addition lubricating oil
In, lubricating oil is expressed into the position of steel ball 3, causes the waste of lubricating oil, while also avoiding the equipment in the process used
In, because the elastic strength of movable spring 16 is excessive to be led to lubricating oil not and can enter steel ball 3 the problem of, improve the hub unit
Practicability, the other end of movable spring 16 is fixedly connected with the bottom of 14 inner cavity of movable oil valve, the initial length of movable spring 16
Degree is greater than the bottom end of motion stops 15 to the distance of 14 intracavity bottom of movable oil valve, and the material of movable spring 16 is stainless steel
Matter, the restriction for 16 initial length of movable spring, avoid even if automobile not when driving, what lubricating oil can be also extruded asks
Topic, further improves the usability of the hub unit, and the bottom end of movable oil valve 14 is fixedly connected with one end of atomizer 17, spray
The other end of oil nozzle 17 runs through and extends to the outer surface of wheel hub 1.
When work, people first open priming valve 11, tighten and add after lubricating oil is injected into grease-box 6 by refueling nozzle
Oil valve 11 squeezes always lubricating oil under the action of compressed spring 8, after driver is driven in automobile to certain speed,
Under the action of centrifugal force can activity compression spring 16 outward, lubricating oil will enter through movable oil valve 14 with atomizer 17 later
To the outer surface of steel ball 3, when the speed of automobile lowers, under the action of the tension of movable spring 16, pushes live inwardly
Dynamic plug 15 blocks movable oil valve 14, and lubricating oil is blocked to go successively to the surface of steel ball 3.
In conclusion the hub unit of the inner ring and ring flange integral structure, passes through movable oil valve 14 and movable spring
16 setting, when the travel speed of automobile reaches certain boundary, centrifugal force caused by the automobile 1 will activity compression bullet
Spring 16 reduces bearing roller so that the lubricating oil in movable oil valve 14 will be flowed into the outer surface of steel ball 3 through atomizer 17
Between friction, effectively raise the service life of hub bearing；It, can be certainly by the setting of grease-box 6 and compressed spring 8
Begin to generate certain pressure to the whole lubricating oil to 6 inner cavity of grease-box, avoid during running car, lubricating oil
The problem of lubricating oil of 6 inner cavity of case cannot timely and effectively be transmitted to the surface of steel ball 3 because sticky excessive, improves in the dress
Set continuity and reliability in use；It solves existing bearing seal structure and is resisting external mud, dust
It is poor in ability, it is general in terms of preventing oil leak, so lubricating oil can be generated in lubricating oil long-term use process
The problem of blackening, toughness increase, performance declines, can not play good lubricant effect, increase the friction between bearing roller,
The problem of seriously reducing hub bearing service life.
