Abstract
The utility model discloses an automobile wheel hub unit, which comprises a mandrel, a screw bolt, a roller, an outer ring, a retainer, an inner ring and an inner ring pressing screw nut, wherein a groove in a key slot shape is formed on external screw threads of the inner ring pressing screw nut and is in interference fit with a wedge block. The automobile wheel hub unit has the advantage that the connection of the inner ring pressing screw nut is more stable and reliable.
Description
Technical field
The utility model relates to the drive disk assembly on a kind of automobile, particularly a kind of automobile hub unit.
Background technology
At present, in many engineering goods such as automobile, used in a large number and be threaded, wherein much be threaded the extremely effect of core of playing is used in the running of engineering goods, in case becoming flexible to cause product to work, even initiation safety misadventure, whether fastening reliably very important, traditional method is to add a lock pin at rear nut if therefore being threaded, or use screw thread glue firmly to be threaded.But these methods can not guarantee fully that screw thread does not become flexible, and particularly when the fastening degree requirement of double threads such as automobile hub bearing hold-down nut is very high, just need a kind of more reliable, firm screw thread chucking structure.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of automobile hub unit, makes the connection of inner ring hold-down nut more solid and reliable.
The utility model technical scheme that adopts of dealing with problems is: a kind of automobile hub unit, comprise mandrel, bolt, roller, outer ring, retainer, inner ring, inner ring hold-down nut, on the outside thread of described inner ring hold-down nut, be provided with the groove of keyway shape, described groove and voussoir interference fit.
The beneficial effects of the utility model are: groove that the inner ring hold-down nut is provided with and voussoir interference fit make the connection of inner ring hold-down nut more solid and reliable.
Description of drawings
Fig. 1 is the sectional structure scheme drawing of the utility model embodiment.
Fig. 2 is the enlarged drawing at I place among the utility model embodiment Fig. 1.
Below in conjunction with accompanying drawing the utility model is described further.
The specific embodiment
As shown in Figure 1, a kind of automobile hub unit, comprise mandrel 1, bolt 2, roller 4, sensor 5, outer ring 6, plastic cage 7, inner ring hold-down nut 9, inner ring A10, inner ring B 12, gear ring 11, on the outside thread of inner ring hold-down nut 9, be provided with the groove of keyway shape, this groove and voussoir 3 interference fit.Poted assemblies 8 makes whole working position form a sealing system, not influenced by dust, prevents the grease outflow.
In when assembling, the coro bearng that assembles is enclosed within on the mandrel 1, be screwed in hold-down nut 9 on the mandrel 1 then and compress bearing cone, at last voussoir 3 is pressed in the geosynclinal concave, as shown in Figure 2, nut will be stuck on mandrel 1 this moment, guarantee the solid and reliable of bearing inner ring predetermincd tension.
