Abstract
The utility model discloses a bus hub driving assembly which comprises a constant speed universal joint, an inner flange, an outer flange, a steel ball holding frame and sealing rings. The bus hub driving assembly is characterized in that the inner flange (3) and the constant speed universal joint are riveted and assembled into an entire hub driving assembly; the inner round surface of the outer flange (5), and the outer round surfaces of the inner flange (3) and the constant speed universal joint (9) are provided with rollaway nests; a nylon holding frame (5) provided with double lines of steel balls, and a nylon holding frame (7) are respectively arranged in the rollaway nests; the rubber sealing ring (4) is arranged between the inner flange and the outer flange; and the rubber sealing ring (8) is arranged between the outer flange (5) and the constant speed universal joint (9). The bus hub driving assembly not only makes products more lightweight and miniaturization, but also removes a spline transmission shaft so that the utility model has more reasonable structure and longer service life.
Description
Technical field originally
The utility model relates to a kind of automobile component, and specifically a kind of car hub drives assembly.
Background technology water
Present existing car hub drives assembly, drives assembly as the patent No. for the ZL200620096190.2 car hub, and its structure is made up of inside and outside flange, inner ring, biserial retainer, steel ball raceway groove and seal ring etc., parts are many, the assembling trouble, inefficiency, quality also is difficult to guarantee.
Summary of the invention
The utility model is at disadvantages of background technology, drive on the assembly basis from product structure at former car hub, processing technology has been done further improvement to assembling, make constant-velocity universal joint and wheel hub drive assembly and made an integral body, this structure is except making more lightweight of product, miniaturization, also abolished spline shaft, the assembling of having eliminated parts such as wheel hub, bearing, constant-velocity universal joint in the conventional confguration cooperates the influence to bearing life, makes structure more reasonable.
The technical solution of the utility model is: a kind of car hub drives assembly, it comprises constant-velocity universal joint, inside and outside flange, ball retainer and seal ring composition, it is characterized in that: inner flange and constant-velocity universal joint riveted joint are assembled into a whole wheel hub and drive assembly; The inner headed face of flange and inner flange and constant-velocity universal joint periphery are provided with raceway outside, be installed in the nylon cages of dress biserial steel ball in the raceway respectively, a rubber seal is installed between the inside and outside flange, and the another rubber seal is installed between outward flange dish and the constant-velocity universal joint.
A kind of car hub described in the utility model drives assembly, and the cylindrical riveted and fixed of the interior circle of its inner flange 3 and fast universal-joint 9 one ends together.
The beneficial effects of the utility model are: constant-velocity universal joint and wheel hub have been made an integral body.This structure is except making more lightweight of product, miniaturization, also abolished spline shaft, the assembling of having eliminated parts such as wheel hub, bearing, constant-velocity universal joint in the conventional confguration cooperates the influence to bearing life, makes structure more reasonable, longer service life.
Attached jail explanation
Fig. 1 is a structural profile scheme drawing of the present utility model.
In the drawings 1, riveted joint face, 2, boss bolt, 3, inner flange, 4,8, rubber Mi Quan, 5, the outward flange dish, 6,7, retainer and steel ball, 9, universal-joint.
The specific embodiment
In the embodiment in figure 1, inner flange and constant-velocity universal joint adopt riveted joint to be assembled into an integral body and drive assembly, and circle in the inner flange 3 (wheel hub) is riveted on the constant-velocity universal joint 9 one end cylindricals; Be respectively equipped with the arc raceway groove on the cylindrical of the cylindrical of inner flange 3 and constant-velocity universal joint 9, circle being provided with two corresponding arc raceway grooves in the flange 5 outside, and two nylon cages 5 and the nylon cages 7 of establishing the biserial steel ball is installed in respectively in the arc raceway groove; Rubber seal 4 is installed between inner flange 3 and outward flange dish 5 joints, and rubber seal 8 is installed between constant-velocity universal joint 9 and the outward flange dish 5; The car hub that assembles is driven assembly be installed in by boss bolt 2 on the wheel of automobile, be connected with propeller-shaft by constant-velocity universal joint 9.
Car hub described in the utility model drives assembly, has adopted new technology and technology at processing, fit on;
(1), adopts the synchronous Grinding Technology of many curved surfaces: outward flange dish two raceway grooves, inner flange and constant-velocity universal joint matching part and raceway groove are adopted synchronous ground finish, improve the product precision; Make constant-velocity universal joint have the characteristics of miniaturization and low heat emission.
(2), adopt the surface heat treatment technology: internally, outward flange dish channel surface, inner flange all adopt the surface heat processing with constant-velocity universal joint matching part surface, constant-velocity universal joint channel surface, guarantee hardness, the rigidity of rolling surface, can not destroy the toughness at other positions of product simultaneously again.
(3), adopt and assemble riveting technology: when assembling, adopt riveted joint to replace traditional nut locking, eliminated the hidden danger that nut is locked tight and nut loosening the integration of inner flange and constant-velocity universal joint.
Compare with traditional fixing type equal speed universal joint, the moment loss when its power transmits has reduced 30%, Effect is more remarkable when adopting big operating angle, and the heat radiation ratio in when running has reduced by 20 ℃. And can Light-weight design and vibration characteristics aspect further improve.
Claims (2)
1, a kind of car hub drives assembly, and it comprises constant-velocity universal joint, inside and outside flange, ball retainer and seal ring composition, it is characterized in that: inner flange (3) is assembled into a whole wheel hub with the constant-velocity universal joint riveted joint and drives assembly; The inner headed face of flange (5) and inner flange (3) and constant-velocity universal joint (9) periphery are provided with raceway outside, be installed in nylon cages (5) and nylon cages (7) that the biserial steel ball is housed in the raceway respectively, rubber seal (4) is installed between the inside and outside flange, and rubber seal (8) is installed between outward flange dish (5) and the constant-velocity universal joint (9).
2, a kind of car hub according to claim 1 drives assembly, and it is characterized in that: the cylindrical riveted and fixed of the interior circle of inner flange (3) and constant-velocity universal joint (9) one ends together.
