Abstract
The utility model discloses a hub bearing assembly comprising an outer ring, an inner ring A, an inner ring B, a central spindle, a gear ring, a retainer frame and a roller, wherein an end of the inner ring A is provided with an extending part, an inner diameter of the gear ring matches with an outer diameter of the extending part arranged at the end of the inner ring A. The hub bearing assembly is simple in structure and long in service life.
Description
Technical field
The utility model relates to the transmission part on a kind of automobile, particularly a kind of small-sized picking-up vehicle hub bearing assembly.
Background technique
At present, hub bearing assembly is as one of component indispensable on the automobile, and main effect is to bear load-carrying and accurate guiding is provided for the rotation of wheel hub.The gear ring of existing automobile hub bearing assembly is directly to be connected with mandrel, and promptly nut is directly contact with gear ring, and general gear ring all adopts the powder metallurgy material; Its hardness and wear resistance are all relatively poor; If nut has looseningly after wheel hub rotates, and just be easy to produce slight crack after the gear ring bump, or even rupture; Not only influence working life, and have potential safety hazard.
Summary of the invention
The utility model technical problem to be solved provides a kind of hub bearing assembly, and is simple in structure, long service life.
The utility model technological scheme that adopts of dealing with problems is: a kind of hub bearing assembly; Comprise outer ring, inner ring A, inner ring B, mandrel, gear ring, retainer, roller; The end of said inner ring A is provided with extension part, and the external diameter of the internal diameter of said gear ring and the set extension part of inner ring A one end is complementary.
Carry and the matrix that rotates and become roller through local induction hardening, mill processing, superfinish the outer ring of the utility model; Advantages such as the interior loop material of the utility model adopts Bearing Steel, and Bearing Steel has high hardness, wear resistance is good and fatigue strength is good.
The beneficial effect of the utility model is: be provided with extension part through inner ring A one end, the internal diameter of gear ring and the external diameter of extension part adopt interference fit to fix, and promptly gear ring is connected with inner ring; Directly do not contact mandrel, nut promptly directly contacts with inner ring, does not influence gear ring; Overall structure is simple, long service life.
