Description
Technical field
The utility model relates to the improvement of automobile-used cross shaft oil seal structure.
Background technique
Universal-joint cross trunnion of the prior art, generally all forms by middle axis body and with the arm that middle axis body links into an integrated entity.But, the Sealing in universal joint and the contact of cross axle poor, therefore its sealability is poor, and dust easily enters into universal joint assembly inside, make between cross axle and bearing support produce wearing and tearing, affect working life.
Model utility content
The utility model, for above problem, provides a kind of structure simple, improves the oil seal structure of sealing and the automobile-used cross axle in working life.
The technical solution of the utility model is: described cross axle comprises cross axle body and bearing, and described cross axle body is provided with oil nozzle; Described bearing housing is located at four ends of described cross axle body, and described bearing comprises axle sleeve and needle roller, and described axle sleeve is set in the end of described cross axle body, and described needle roller is located between the inner side of described axle sleeve and the end circumferential surface of described cross axle body;
Described oil seal structure be set in described cross axle body end and between described needle roller and the axle journal place of cross axle body, described oil seal structure comprises the oil sealing body and baffle ring that are connected as a single entity, described baffle ring has up-small and down-big shoulder hole, the little shoulder hole of described baffle ring is towards described needle roller, the surrounding of the large shoulder hole of described baffle ring is provided with rib, and described rib contacts the end face of described axle sleeve towards the axle journal place of described cross axle body.
The axle journal place of described cross axle body is provided with step circle, described oil sealing body towards the axle journal place of described cross axle body end thereof contacts described in step circle.
The utility model arranges bearing in the end of cross axle body, and bearing comprises axle sleeve and needle roller, then is sealed by oil seal structure, and be reliably connected on the end of cross axle body, reliability is high, improves sealing; At work, contact axle sleeve, towards the end face at the axle journal place of cross axle body, connects reliable, dust-proof the rib of baffle ring; Oil sealing body is set in the end of cross axle body, and meanwhile, contact step circle, seals reliable, dust-proof.The convenient processing of the utility model, simple and reasonable for structure.
