Abstract
Provided is a hub assembly for oil lubrication. The hub assembly for oil lubrication comprises a hub body, an outer conical roller bearing, an inner conical roller bearing and a hub oil seal. The hub assembly for oil lubrication is characterized in that a plurality of oil ways from a cavity between the hub oil seal and the inner conical roller bearing to a cavity between the inner conical roller bearing and the outer conical roller bearing are evenly arranged on the hub body in the circumferential direction. When a car runs, according to the hub assembly, the oil increased in the cavity between the inner conical roller bearing and the hub oil seal can flow back to the cavity between the inner conical roller bearing and the outer conical roller bearing through the oil ways, and therefore the possibility of oil leakage in the hub oil seal is reduced.
Description
Technical field
The utility model relates to a kind of Hub assembly, specifically relates to a kind of Hub assembly that is applicable to oil lubrication.
Background technology
The leakage of oil of in use can losing efficacy of the hub oil seal of oil lubrication of the prior art.
The Hub assembly of oil lubrication of the prior art does not provide custom-designed back oil road between the cavity of neck bearing and hub oil seal.In vehicle traveling process, because the pumping effect of tapered roller bearing makes that the oil mass between neck bearing and the hub oil seal constantly increases, oil pressure constantly raises, and causes the oil sealing leakage of oil.
The utility model content
At the problem of the hub oil seal leakage of oil of present oil lubrication, the utility model provides a kind of Hub assembly for oil lubrication.
This kind is used for the Hub assembly of oil lubrication, comprise hub body, outer cone coro bearng, female cone coro bearng, hub oil seal, it is characterized in that: described hub body circumferentially be evenly distributed with cavity between several hub oil seals and the neck bearing lead in the oil duct of cavity between the outer bearing.
Hub assembly is in vehicle traveling process, make oil mass that cavity between neck bearing and the hub oil seal increases to flow back into cavity between the inside and outside circle taper roller bearing by oil duct, keep the oil pressure in the cavity between neck bearing and the hub oil seal, reduced the possibility of hub oil seal leakage of oil.
Description of drawings
Fig. 1 is the part sectional view of the Hub assembly for oil lubrication of the present utility model;
Fig. 2 is the sectional side view of middle hub body embodiment illustrated in fig. 1;
Fig. 3 is the front view of middle hub body embodiment illustrated in fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Referring to Fig. 1, the utility model is applicable to the Hub assembly of oil lubrication, comprises hub body 2, outer cone coro bearng 1, female cone coro bearng 3, hub oil seal 4.Described hub body 2 circumferentially be evenly distributed with the oil duct c that cavity a between a plurality of hub oil seals and the neck bearing leads to the cavity b between the inside and outside circle taper roller bearing.The sectional side view of hub body 2 and front view are shown in Fig. 2,3.
As shown in Figure 1, automobile under steam, when using the Hub assembly for oil lubrication of the present utility model, the oil among the cavity a can flow into cavity b by back oil road c, make that oil mass and the oil pressure among the cavity a can not raise, and has reduced the possibility of hub oil seal leakage of oil.
