Model utility content
The technical problems to be solved in the utility model is to provide a kind of hub bearing oil lubrication structure being applicable to passenger vehicle disc-type front axle, solve above problem, without the need to dismounting wheel limit component in maintaining process, only tank filler sleeve on hubcap need be opened and release old lubricant oil, then rejoin new oil.
The technical solution of the utility model is:
Be applicable to a hub bearing oil lubrication structure for passenger vehicle disc-type front axle, the front-end and back-end of hub inner lumen are provided with hub bearing, and knuckle to penetrate in hub inner lumen and is connected with hub bearing; Described hub bearing oil lubrication structure includes the hubcap being arranged at wheel hub front end, is arranged at spacer ring and the hub oil seal of wheel hub rear end; Described hubcap to be fixedly connected with the front end of wheel hub by hub nut thus to be sealed the front end of wheel hub, and the front end of knuckle extend in hubcap, and hubcap is provided with oil hole; Described hub oil seal is placed in the rear end of hub inner lumen, and spacer ring is placed between hub oil seal and knuckle, and the exterior edge face close contact of the interior edge face of spacer ring and corresponding hub bearing inner ring.
Described hub bearing oil lubrication structure also includes locking mechanism, and locking mechanism includes locking nut, annular locking plate and clip; Described annular locking plate is provided with a circle hole, annular locking plate inner ring centered by groove; Described locking nut include annular chassis, with annular chassis interior edge face one plasticity nut, the outer wall of nut is provided with annular slot, annular chassis is provided with multiple fixed hole; Described clip includes ring part and is fixedly connected on the bending pillar on ring part outer wall, and the ring part of clip is embedded in the annular slot of nut; The exterior edge face of described locking nut annular chassis and the interior edge face of annular locking plate are fitted, locking nut, annular locking plate are all set in knuckle axle journal end, the exterior edge face of annular locking plate contacts with the exterior edge face of corresponding hub bearing inner ring, inner ring screw thread and the knuckle axle journal end thread of locking nut are screwed together thus are locked by ring lock sheet, and both are fixed through the fixed hole of locking nut, the positioning hole of annular locking plate by described clip bending pillar successively.
Described hubcap is provided with relief hole.
Advantage of the present utility model:
(1), the utility model passes through hubcap, spacer ring and hub oil seal by the bore seal of wheel hub, then inner chamber lubricant oil being injected wheel hub by oil hole lubricates hub bearing, can sufficient lubrication hub bearing, and reduce the maintaining cost of car load in the later stage;
(2), locking mechanism of the present utility model meets the axial locking of wheel hub and the play of guarantee hub bearing;
(3) relief hole, on the utility model hubcap, can be exhausted pressure release by the chamber pressure rocking generation due to lubricant oil in car load running, ensure that the normal use of wheel hub.
