Description
Technical field
The present invention relates to a kind of hub-bearing unit, specifically is third generation hub-bearing unit, belongs to automobile technical field.
Background technique
The main effect of automobile hub bearing is load-bearing and for the rotation of wheel hub provides accurate guiding, and it not only bears thrust load but also bear radial load, is a very important device.Hub-bearing unit is on the basis of standard angle contact ball bearing and tapered roller bearing, to grow up; It is manufactured two sleeves and is integral; Have the assembling performance good, can omit play adjustment, in light weight, compact structure, load bearing capacity big, omit the external hub sealing and avoid advantage such as maintenance; Be widely used in the car, the progressively trend of expanding application has also been arranged in truck.
The structure of conventional wheel hub bearing unit is as shown in Figure 3; Comprise the conventional flange plate 8-1 that is used for fixing wheel hub, be fixed on the vehicle frame and and the conventional outer ring 6-1 of flange plate coupling, be installed in ball 4-1 between outer ring and the flange plate, be used for the inner ring 10 spacing said ball, and be used for last black box 5-1 (having sensor) and lower seal assembly 7-1 with the space sealing between outer ring and the flange plate.Said inner ring is set on the flange plate, prevents that the ball slippage from coming out; Said upward black box and lower seal assembly are installed in the two ends of outer ring respectively, and the space between outer ring and the flange plate is filled with lubriation material.The shortcoming of this type of hub-bearing unit is: need inner ring be pressed into and lock play with press when 1, installing; In this process, need to consider the matching problem between inner ring and the flange plate; Processing and installation are all not too convenient, bring certain trouble for the maintenance work of automobile; 2, be provided with two groups of balls in this type of hub-bearing unit, every group of ball is respectively through a conventional retainer 1-1 location, and each conventional retainer needs to install respectively during installation, and process is comparatively loaded down with trivial details, and working efficiency has much room for improvement; 3, structure relative complex, product consumption material is more, and weight is corresponding bigger, and cost also is difficult to descend.
Summary of the invention
The objective of the invention is to overcome the deficiency in the above-mentioned background technology, a kind of improvement of hub-bearing unit is provided, this hub-bearing unit should have easy assembling, characteristics simple and compact for structure, easy to process.
The technological scheme that the present invention adopts is: third generation hub-bearing unit; Comprise the flange plate that is used for fixing wheel hub; This flange plate forms an integral body near a side and the bearing inner ring at car body center; The coaxial bearing outer ring that is fixed on the car body that is arranged with is provided with two groups of bearing balls on the said bearing inner ring in the space between bearing outer ring and the bearing inner ring, and the two ends in this space are respectively through last Sealing and lower seal sealing; It is characterized in that: be shaped on the circle bulge loop spacing to said bearing ball on the outer wall of said bearing inner ring near car body center one end, this bulge loop and bearing inner ring are one-body molded and protruding along the radial outward of bearing inner ring; Said two groups of bearing balls are installed on the same retainer; This retainer comprises the retainer body of a ring-type; One side edge of retainer body is shaped on one group of mounting groove along its circumferential array, and the opposite side edge is shaped on one group of retraction slot, and arrange said mounting groove and retraction slot space; The opening of mounting groove and retraction slot is shaped on the installation station of two bearing balls respectively all along the axis arranged of retainer body and in the opposite direction in each mounting groove.
Be shaped on raceway groove on the outer wall of said bearing inner ring and the inwall of bearing outer ring with said bearing ball coupling.
Said retainer body and bearing inner ring coaxial arrangement.
Installation method of the present invention is: retainer is installed between bearing outer ring and the bearing inner ring; Afterwards bearing outer ring is upwards promoted; Make the spacing on bearing outer ring and bearing inner ring top become big, can bearing ball be installed in the mounting groove of retainer then, installing after what a mounting groove turns an angle retainer installs the bearing ball of another mounting groove again; Install until all bearing balls, at this moment bearing outer ring, retainer, bearing inner ring coaxial arrangement.
The invention has the beneficial effects as follows: the present invention is a direct one-body molded bulge loop on bearing inner ring; The inner ring that replaces the conventional wheel hub bearing unit; On the basis that guarantees the hub-bearing unit proper functioning; Reduced production and installation procedure, structure is more simple and reliable, has also avoided the matching problem of inner ring and flange plate in the conventional wheel hub bearing unit; And having reduced product weight (alleviating more than 50%) significantly, the mounting structure of car body also can alleviate corresponding weight, has reduced cost of production; In addition, the present invention is installed to two groups of bearing balls on retainer of bucket, and operator only need install once and get final product, high working efficiency, and production and processing is also more convenient, is particularly suitable for small-sized electric vehicle, has market prospects preferably.
