Description
Technical field
The present invention relates to automobile bearing part field more particularly to a kind of lightweight hub bearing units.
Background technique
The hub bearing components one of important as automobile play and guarantee the stable work with supporting body of vehicle wheel rotation
With.But it constantly brings forth new ideas with the continuous progress of technology with new material, under the lightweight trend of automobile entirety, the progress of technology
It is required that being continuously improved, hub bearing is required also higher and higher.
It experienced several generations differentiation, the structure of hub bearing increasingly integration, structure tends to be integrated into entirety.Weight but also
Increase therewith due to needing additional materials to fill up the fit-up gap of original part.Not only bring biggish inertia mass, shadow
Acceleration and the braking distance for ringing automobile, can also be such that Oscillation Amplitude increases, and damping effect reduces.
Then more researchs and calculating have been made to hub spindle.Internal and external cycle and de-material are integrated in double row ball bearing
The bearing body structure of the ring flange of processing and two-way removal material.The load character for inheriting ball bearing saves manufacture
Material is equivalent to and reduces wheel total quality.
Increase in the prior art since the integration feature of each generation bearing causes hub bearing weight, makes the vibration frequency of wheel hub
Rate improves, and damping is caused to be difficult to the disadvantages of quickly absorbing vibrational energy.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of light-duty wheel for defect involved in background technique
Hub bearing unit.
The present invention uses following technical scheme to solve above-mentioned technical problem:
A kind of lightweight hub bearing unit includes ring flange, inner ring, outer ring and retainer;
The ring flange includes flange side surface and long end shaft neck;
The long end shaft neck, inner ring, outer ring are coaxially disposed from the inside to the outside, and the inner ring is fixed on the long end shaft neck;
The outer wall of the inner ring, the inner wall of outer ring are equipped with the first raceway matched, outer wall, the outward flange of the long end shaft neck
The inner wall of disk is equipped with the second raceway matched;
Several balls are equipped in first raceway, the second raceway;
The retainer is stepped, and a part is arranged between long end shaft neck and outer ring, and a part is arranged in inner ring and outer ring
Between, which is provided with the one-to-one pocket hole of ball in the first raceway, the second raceway, for and first raceway, second
Ball in raceway matches;
The flange side surface last week, the both ends of the arc-shaped groove structure were equal at least three arc-shaped groove structures are uniformly provided with
For rounded structure.
As a kind of further prioritization scheme of lightweight hub bearing unit of the present invention, the number of the arc-shaped groove structure
It is four, the range for corresponding to central angle is 60 ° ± 10 °.
As a kind of further prioritization scheme of lightweight hub bearing unit of the present invention, the retainer is by GCr15 material
It is made.
As a kind of further prioritization scheme of lightweight hub bearing unit of the present invention, first raceway, the second raceway
The margin of tolerance of interior ball and the retainer fit dimension is ± 0.1mm.
As a kind of further prioritization scheme of lightweight hub bearing unit of the present invention, it is equipped between the outer ring and inner ring
Sealing ring.
The invention adopts the above technical scheme compared with prior art, has following technical effect that
1. bearing arrangement, in high-speed motion, the ladder-type structure of retainer ensure that lubricating oil utmostly touches ball
Maximum cross-section makes lubrication sufficiently uniformly be covered with entire spherical surface, while having played maximum heat radiation function;
2. the outward flange of notching construction due in driving process high-speed rotation and translational motion drive in its cavity air to flow,
Heat dissipation performance is enhanced, hub interior temperature is further decreased;
3. the steps design of retainer moves synchronously the ball in two class raceways, it is effectively reduced vibration problem and noise,
Open end facilitates the injection of lubricating oil.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure, 1- ring flange, the outer ring 2-, 3- inner ring, the ball in the first raceway of 4-, the ball in the second raceway of 5-.
Specific embodiment
Technical solution of the present invention is described in further detail with reference to the accompanying drawing:
The present invention can be embodied in many different forms, and should not be assumed that be limited to the embodiments described herein.On the contrary, providing
These embodiments are thoroughly and complete to make the disclosure, and will give full expression to the scope of the present invention to those skilled in the art.
In the accompanying drawings, for the sake of clarity it is exaggerated component.
As shown in Figure 1, including ring flange, inner ring, outer ring and holding the invention discloses a kind of lightweight hub bearing unit
Frame;
The ring flange includes flange side surface and long end shaft neck;
The long end shaft neck, inner ring, outer ring are coaxially disposed from the inside to the outside, and the inner ring is fixed on the long end shaft neck;
The outer wall of the inner ring, the inner wall of outer ring are equipped with the first raceway matched, outer wall, the outward flange of the long end shaft neck
The inner wall of disk is equipped with the second raceway matched;
Several balls are equipped in first raceway, the second raceway;
The retainer is stepped, and a part is arranged between long end shaft neck and outer ring, and a part is arranged in inner ring and outer ring
