Abstract
The utility model discloses a blocking bowl self-adjusting wheel hub for an automobile. The utility model adopts the way that an inner blocking bowl and an outer blocking bowl are respectively arranged the inside of bearings of both ends of a wheel hub, an oil seal is arranged on a blocking plate of the front end of the blocking bowl, the back ends of the two blocking bowls are provided with a central spring, and lubricating oil which is stored on the front side of the blocking bowl is continuously pushed toward each bearing by the two blocking bowls under the thrust of the central spring so as to ensure that the normal lubrication of each bearing. The utility model has the advantages of little oil, good lubricating performance, and long maintenance interval time; the utility model is an ideal product for replacing an old product at present.
Description
The utility model relates to a kind of wheel nave of power actuated vehicle.
At present, the structure of traditional automotive hub is all to leave the space between the bearing of wheel hub both sides, although all contain sufficient lubricating oil fat in its space when maintenance.But along with the high speed revolution of wheel and bearing, the lubricating oil in the bearing is extruded, and the oil of extruding can not return bearing, is thrown to deposition, aging in the middle bulge of wheel hub at last under action of centrifugal force.Along with the rotation of wheel hub, the lubricating oil on the bearing is fewer and feweri, and as untimely interpolation, bearing will can not travel because of the oil starvation sintering.Therefore this traditional wheel hub in use not only the maintenance shop interval short, lubricant effect is not good, the service life of bearing is short, but also has wasted a large amount of lubricating oils, has brought unsafe hidden danger to driving.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of self-adjustable oil storage shelves bowl, to satisfy the auto-supply of bearing.
Scheme of the present utility model is made up of hub body, shelves bowl, bearing, central spring etc., its constructional feature is that the inboard of two bearings is provided with inside and outside two shelves bowls inside and outside wheel hub, on the front end shelves dish of two grades of bowls oil sealing is housed respectively, central spring is equipped with in the rear end of shelves bowl, and the inboard of inside and outside two bearings is provided with zerk.The outer bottom side of wheel hub is provided with the draining hole, and the nose end exit is provided with spill valve, and the zerk lubricating oil of can annotating at any time as required, two grades of bowls are constantly pushed the lubricating oil that stores to bearing under the thrust of central spring, and is enough lubricated to guarantee.
The utility model has the advantages that simple in structurely, reasonable in design, refuel fewly that lubricity is good, grease degree of utilization height, the maintenance shop interval is long, and the while has also prolonged wheel hub, the service life of hub spindle and bearing.
Be described further below in conjunction with accompanying drawing:
Fig. 1 is the wheel hub structure scheme drawing;
Fig. 2 is a grade bowl structure scheme drawing;
The inside and outside two ends of wheel hub are equipped with neck bearing 1, outer bearing 8 respectively among Fig. 1, the inboard of interior outer bearing is provided with home record bowl 3, overside bowl 6, on the front end shelves dish of two grades of bowls oil sealing 2 is housed respectively, the rear end is installed in the two ends of central spring 5 respectively, the inboard of bearing is respectively equipped with interior zerk 4, outer zerk 7, the outer bottom side of wheel hub is provided with draining hole 9, and the nose end exit is provided with spill valve 13, and the middle part system of wheel hub is used tire screw hole 10.
The front end shelves dish of the middle-grade bowl of Fig. 2 is provided with oil seal groove 11, and the rear end is shaped on shelves bowl seat 12, and shelves bowl oil sealing is installed in the oil seal groove during use, and central spring is sleeved on the shelves bowl seat 12.
