Abstract
The utility model discloses an oil lubrication supporting bridge hub unit, which comprises an outer ring, a first inner ring and a second inner ring of a hub and bearings, wherein the bearings are arranged in the first inner ring and the second inner ring respectively. The oil lubrication supporting bridge hub unit is characterized in that an oil retaining disk fixed onto the outer ring of the hub is arranged on the outside of the second inner ring of the hub. After novel technology is adopted, the integral performance of the hub is improved, the additionally arranged oil retaining disk is capable of effectively preventing lubricating oil from entering a scraper after leaking, double spigots with stepped structures are also beneficial for solving the problems of weak positions caused by insufficient space of a brake drum and the like, and an oil throwing hole communicated with an oil storage cavity is capable of removing the leaked lubricating oil in time, so that a brake is protected.
Description
Technical field
The utility model relates to automotive field, is specifically related to a kind of oil lubrication supporting bridge hub.
Background technology
Present domestic trailer vehicle bridge factory all develops the oil lubrication vehicle bridge, and increasing user also produces higher interest to this series products.Yet the leak tightness of the lubricated axletree of fluid oil is subjected to one to concern too as the leading indicator of new product, in case the leakage of lubricating oil takes place, lubricating oil enters drg, will produce extinction to car load.Therefore when satisfying leak tightness, also to strengthen protection, take corresponding secondary protection function it.Simultaneously wheel hub is also carried out in double stopper location, the big round-corner transition of steel ring stop portion and the wheel hub optimal designs such as muscle.
Summary of the invention
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of performance of improving wheel hub is provided, and improves its reliability, the leakage of lubricating oil played the oil lubrication supporting bridge hub of certain protection effect.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of oil lubrication supporting bridge hub, comprise wheel hub outer ring, first inner ring, second inner ring and be located at first inner ring, the interior bearing of second inner ring respectively, the described wheel hub second inner ring arranged outside has the oil baffle disc that is fixed on the wheel hub outer ring.
Above-mentioned oil lubrication supporting bridge hub offers the oilhole that gets rid of that leads to oil storage cavity that wheel hub second inner ring outside and oil baffle disc form on the described wheel hub outer ring.
Above-mentioned oil lubrication supporting bridge hub is provided with reinforced rib between the described wheel hub outer ring and first inner ring.
Above-mentioned oil lubrication supporting bridge hub, the described wheel hub outer ring and the first inner ring junction are provided with fillet structure.
Above-mentioned oil lubrication supporting bridge hub, ora terminalis place, described wheel hub outer ring is provided with ledge structure.
The advantage of the utility model oil lubrication supporting bridge hub is: after employing new technology; improve the overall performance of wheel hub; the oil baffle disc of setting up can effectively prevent to enter strigil after the oil leak; double stopper with ledge structure also helps improving brake wheel and occurs problems such as weakness because of insufficient space; the oilhole that gets rid of that communicates with the oil storage cavity can be in time got rid of the lubricating oil that leaks, and protect drg.
Description of drawings
Fig. 1 is the structural representation of the utility model oil lubrication supporting bridge hub.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further details;
As shown in Figure 1, structural representation for the utility model oil lubrication supporting bridge hub, comprise wheel hub outer ring 1, first inner ring 2, second inner ring 3 and be located at bearing 4 in first inner ring 2, second inner ring 3 respectively, the arranged outside of described wheel hub second inner ring 2 has the oil baffle disc 5 that is fixed on the wheel hub outer ring 1.On wheel hub outer ring 1, offer lead to oil storage cavity 6 that wheel hub second inner ring, 3 outsides and oil baffle disc 5 form get rid of oilhole 7.For improving the firm performance between the wheel hub outer ring 1 and first inner ring, between the described wheel hub outer ring 1 and first inner ring 2, reinforced rib 8 is set around its line of centers, the quantity of reinforced rib 8 can be set according to concrete different bearer amount.For reducing stress concentration, improve the intensity of wheel hub, in wheel hub outer ring 1 and first inner ring, 2 junctions fillet structure 9 is set.For improving location efficiency and mounting stability, 1 ora terminalis place is provided with ledge structure 10 in the wheel hub outer ring.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
