Abstract
A special hub for an oil lubrication axle belongs to an accessory on a semi-trailer axle. The special hub comprises a hub body and a flange, wherein an inner bearing position and an outer bearing position are formed in the hub body; and the special hub is characterized in that a through hole with threads is formed in a side wall between the inner bearing position and the flange in the hub body, so that waste oil in a hollow cavity of the hub can be discharged, and a bolt is installed in the through hole. The special hub has the advantages that under the condition of not dismantling the hub, the waste oil in the hub can be thoroughly discharged, so that a bearing can be more convenient to maintain, and the cost is lowered; and the bolt can absorb inside scrap iron, lubricating oil is kept clean, the bearing is prevented from being accidentally damaged, and the service life of the bearing is prolonged. The special hub is mainly applied to the oil lubrication car axle.
Description
Technical field
The utility model relates to the accessory on a kind of vehicle bridge, relates in particular to a kind of wheel hub of superimposed trailer vehicle bridge.
Background technology
Wheel hub is the main accessory on the vehicle bridge, comprise hub body, flange and inside and outside bearing position etc., after wheel hub installed on the vehicle bridge, there were two bearings inside, respectively neck bearing and outer bearing, along with the progress of technology, originally the vehicle bridge bearing is to use semi-solid grease lubrication, and now increasing bearing adopts fluid oil lubricated, using the lubricated vehicle bridge of fluid oil to need not to lay down wheel hub just can change oil, maintenance side is very convenient, and cooling-down effect is better, can also prolong the life-span of bearing.The fluid oil of oil lubrication vehicle bridge is that can is in the internal cavity of wheel hub, weak point was when existing wheel hub was used for the oil lubrication vehicle bridge: the cavity that the larger depression of diameter is arranged between the inside and outside bearing position of wheel hub, oil in this cavity safeguards always have some residual when changing oil at ordinary times, sump oil can not thoroughly be changed, reduced the effect of safeguarding.
Summary of the invention
Problem to be solved in the utility model is to improve existing wheel hub, makes it in situation about need not dismantle, and just can thoroughly bleed off the sump oil in the wheel hub, also can easily clear up the iron filings in the wheel hub.
In order to address the above problem, the utility model provides a kind of oil lubrication vehicle bridge special wheel hub, comprise hub body and flange, neck bearing position and outer bearing position are arranged in the hub body, it is characterized in that: a threaded through hole is set on the sidewall between hub body neck bearing position and the flange, this through hole can be emitted the greasy dirt in the hub cavity, and a bolt is installed in the through hole.
Further improvement of the utility model, the through hole position is provided with a drainage groove on the inwall of described hub body, all flows to the aperture with the oil that makes things convenient for the wheel hub inner chamber and emits.
The utility model compared with prior art, advantage is: can be in the situation of not dismantling wheel hub, can thoroughly emit the greasy dirt in the wheel hub, make bearing maintenance convenient, cost is lower; The utility model is used for the automotive axle of oil lubrication.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the front view of oil lubrication vehicle bridge special wheel hub.
Fig. 2 be among Fig. 1 oil lubrication vehicle bridge special wheel hub A-A to cutaway view.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises hub body 1 and flange 2, neck bearing position 3 and outer bearing position 4 are arranged in the hub body 1, it is characterized in that: a threaded through hole 5 is set on the sidewall between hub body 1 neck bearing position 3 and the flange 2, bolt 6 of through hole 5 interior installations, bolt 6 can be the magnetic material of tool, is used for the iron filings in the absorption wheel hub, and through hole 5 positions are provided with a longitudinally drainage groove 7 on the inwall of hub body 1.
