Abstract

The utility model relates to an automotive wheel rim bearing component, which belongs to the field of automotive parts. The cage of the prior integrated automotive wheel rim bearing component adopts an integral type, and all parts need to be disassembled for rematching if either the inner ring or the steel ball does not meet the requirement in size, so the assembling efficiency is very low. The cage of the automotive wheel rim bearing component adopts a split type; each cage comprises an integral round disc and axial isolation teeth; the axial isolation teeth are arranged on the end surface of one end of the round disc along the circumferential direction and mounted among the steel balls in an insertion way; a positioning snap ring is arranged on the end surface of the other end of the round disc of the cage; one side of the outer circular surface of each inner ring is provided with a clamping groove; the two inner ring clamping grooves are mounted adjacently; and the positioning snap ring of the cage is clamped in the clamping groves to limit the axes of the cage. With the utility model, only the parts which do not meet the requirements are disassembled and assembled during the matching and assembly of the bearing component, so the assembling efficiency is improved.

Description

The automobile hub bearing assembly
Technical field
The utility model belongs to the auto parts and components field, and is especially relevant with a kind of automobile hub bearing assembly.
Background technology
The orthodox car bearing-hub assembly mainly is made up of bearing seat and bearing, bearing seat is made up of flange that is connected as a single entity and tubular pedestal, two bearing serial connections are installed in the pedestal, and the integrated automobile hub bearing assembly is bonded into one with the outer ring and the pedestal of bearing, process two raceway grooves on the present intracoelomic cavity wall, with the inner chamber of steel ball, retainer and inner ring embedded pedestal as the outer ring.The retainer of existing integrated automobile hub bearing assembly adopts integral type, the retainer of promptly forming two bearings of the bearing-hub assembly composition integral type that is connected as a single entity, during assembling, inner ring and steel ball are the assembling of apolegamy form, as long as when having one of them not meet dimensional characteristic,, will all dismantle again with regard to needs and match because retainer is an integral type, the assembling of bearing-hub assembly is lost time very much, and efficiency of assembling is very low.
The utility model content
The purpose of this utility model will overcome the existing inefficient defective of integrated automobile hub bearing assembled exactly, and a kind of easy assembling, automobile hub bearing assembly that efficiency of assembling is high again are provided.For this reason, the utility model is by the following technical solutions:
The automobile hub bearing assembly, comprise bearing seat as outside race, steel ball and bearing inner ring, bearing seat is made up of flange that is connected as a single entity and tubular pedestal, base vivo wall is provided with two raceway groove, corresponding with the raceway groove respectively pedestal inner chamber that is installed on of steel ball and inner ring constitutes by steel ball, two inner rings and one is the bearing assembly formed of the bearing seat of outer ring as a whole, it is characterized in that: described bearing assembly also comprises two retainers, retainer comprises the disk that is connected as a single entity and along the circumferential direction is arranged at axial isolation tooth on the disk one end end face, isolate tooth and be plugged between the steel ball, the other end end face of disk is provided with the location snap ring; Described inner ring periphery one side is provided with the draw-in groove that is used for the retainer axial location, two adjacent installations of inner ring draw-in groove; The location snap ring of described retainer is installed in the draw-in groove of described inner ring, and retainer is made axial location.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Be provided with poted assemblies between the end of described pedestal and the inner ring, bearing assembly is played sealing and dustproof effect.
The utility model can reach following beneficial effect: the utility model retainer adopts split type, can match each inner ring and steel ball respectively, avoided not dismantling all, made assembling easily, improved efficiency of assembling owing to one of them inner ring or steel ball meet dimensional characteristic.
