Description

METHOD OF ASSEMBLING A WHEEL HUB ROLLING BEARING ASSEMBLY BY HEAT SHRINKING A RETAINER RING
Technical Field
This invention is related to the mounting method of a wheel hub assembly as an independent unit which has been integrated with roller bearings used in the front and rear wheel connections of passenger vehicles and light commercial vehicles.
The invention is particularly related to a mounting method of a retainer ring which is fixed to the end of the wheel hub, after it is expanded by heating, in order to fix the inner ring at an axial direction following the installation of all components onto the wheel hub.
Prior Art
The wheel hub assembly known in the art is formed of two ball bearings, a hub which acts as an inner ring for one of the bearings, wheel nuts which couple the hub to the wheel rim, a frame which holds the bearing, ball or rollers together, impermeability elements acting as both an external ring which is mounted on both sides of the external ring with flange having lugs and holes that allow the coupling of the wheel hub assembly to the front and rear axle assembly. Various methods are used in order to fix the inner ring at an axial direction after said components are brought together.
According to the German Patent document numbered DE4023016 of the known state of the art, a retainer ring used to the fix the inner ring onto the hub at an axial direction is described. The retainer ring is snug fitted onto the end of the hub and it is then welded to the end of the hub. The international patent document numbered WO2010012284 of the known state of the art describes an application where the end of the hub is folded outwards in order to fix the inner ring at an axial direction. The patent document numbered CN101501354 A of the known state of the art describes an application where after the inner ring is mounted over the hub, the hollow hub part that has been mounted is blown up from the inside or it is orbitally swaged or if the part where the inner ring is mounted on is shaped like a non- hollow shaft, the inner ring is axially fixed by means of a nut and a screw that is opened toward said section.
Besides these applications a screw or a nut is frequently used in order to fix the inner ring at an axial direction. In order to fix the inner ring at an axial direction, the method of orbital swaging of the end section of the shaft that is mounted onto the inner ring and the method of plastering onto the inner ring, necessitate the addition of a machine onto the wheel hub assembly mounting line which carries out orbital swaging. This brings about additional costs in terms of investment.
When all of these reasons and disadvantages are taken into consideration, the need for an easier application to fix the inner ring onto the hub at an axial direction has risen. Aims of the Invention
The aim of the invention is to provide a mounting method for fixing the inner ring at an axial direction following the installation of all of the components onto the wheel hub. Another aim of the invention is to provide a mounting method which eliminates the need to plaster the shaft that is mounted onto the inner ring by means of orbital swaging the shaft to the side surface of the inner ring. The mounting method carried out in order to reach the aim of the invention comprises the steps of installing all of the components onto the wheel hub and mounting of a retainer ring which is fixed to the end of the wheel hub, after it is expanded by heating, in order to fix the inner ring at an axial direction.
Detailed Description of the Invention
The wheel hub used in the mounting method that has been provided in order to reach the objects of the invention has been illustrated in the attached figures.
According to said figures;
Figure 1, is the side section view of the wheel hub that has been obtained by the method of the invention.
The parts in the figures have each been numbered as follows.
1. Hub
2. External ring
3. Cage
4. Inner ring
5. Retainer ring
6. Sealing
7. Ball
8. Wheel belt
9. Hub end The wheel bolts (8) which enable the connection of the wheel rim into the present holes located on the hub (1) obtained by means of the method of the invention, a sealing (6) which prevents the leakage of lubricants located inside the bearing and at the same time which prevents contamination from the external environment from entering into the hub, balls (7) which enable the rolling of the bearing, cage (3), external ring (2) with flange and the inner ring (4) are mounted by means of the method known in the art. Following this, the retainer ring (5) is heated and shrink fitted to the end (9) of the hub (1) which is mounted over the inner ring (4).
The inner diameter of the retainer ring (5) is either equal to or smaller from the diameter of the end (9) of the hub. The retainer ring (5) is heated and expanded in order for it to be mounted over the end (9) of the hub, and it is mounted to the end (9) of the hub when it is at an expanded state and following this when the retainer ring (5) is cooled down, it is compressed and therefore shrink fitted to the end of the hub. By this means the fixation of the inner ring (4) at an axial direction is provided.
The heating of the retainer ring (5) can be provided by means of an induction heating system that can be added to the automatic assembly line. Therefore both the heating time is shortened and the mounting work-flow will not be disturbed. Moreover the addition of a heating system to the mounting line shall both be easy and low in cost.

Claims
