The present invention relates to a hub embodiment for use in the front and rear axle shafts of the construction equipment and tractors. PRIOR ART

Planet gear pins may axially move in a single direction (outwardly) due to the effect of the axial loads occurring as a result of various user errors and/or during the operation in the pins of the hubs provided in the axle shafts. As a result of the axial movement, undesired problems may occur like changes in the package size, verticality errors in the pins, abrasions in the front washers and inner snap ring provided in the planet gear pins, and as a result of these, damages may occur in the hub group.

As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.

BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to a hub embodiment, for eliminating the above mentioned disadvantages and for bringing new advantages to the related technical field.

The main object of the present invention is to provide a hub embodiment which prevents the axial movement which may occur as a result of the effect of axial loads. In order to realize all of the abovementioned objects and the objects which are to be deducted from the detailed description below, the present invention is a hub embodiment for use in the front and rear axle shafts of the construction equipment and tractors and having a planet gear pin whereon a planet gear is positioned. Accordingly, the hub embodiment comprises a pin housing wherein the planet gear pin is placed, a channel provided at the inner wall of said pin housing and an outer snap ring positioned inside said channel. Thus, usage of planet gear pin, having the same sizes in the hubs of vehicles with engines which work at different horse powers, becomes possible since axial movement can be prevented. In a preferred embodiment of the invention, the planet gear pin is rested onto the outer snap ring.

In another preferred embodiment of the invention, at least one bearing is provided between the planet gear and planet gear pin.

In another preferred embodiment of the invention, said bearing is a roller bearing.

In another preferred embodiment of the invention, at least one inner snap ring is provided which is placed in an inner snap ring channel provided on the planet gear pin. Thus, the bearing and the planet gear can be prevented from removing from their places.

In another preferred embodiment of the invention, at least one front washer is positioned between the inner snap ring and the bearing.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter hub (10) embodiment is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

The subject matter hub (10) embodiment essentially comprises a sun gear (80), a planet gear (40) connected to said sun gear (80), a planet gear pin (20) providing connection of said planet gear (40) to the hub (10), and an outer snap ring (70) connected to said planet gear pin (20).

The hub (10) describes the section where the wheels are connected in vehicles like construction equipment and tractors. The sun gear (80) is positioned in a manner centered at the center section of the hub (10). There are planet gears (40) which are positioned around the sun gear (80) and connected to the sun gear (80). In the preferred embodiment, there are three planet gears (40) connected to the sun gear (80).

There is a pin housing (1 1 ), which has hole form, on the hub (10). The planet gear pin (20) is placed in a snap-fit manner on said pin housing (1 1 ). The planet gear pin (20) is provided in a cylindrical form. The planet gear pin (20) is separated as the hub side (22) and the bearing side (21 ). The diameter of the bearing side (21 ) is smaller than the diameter of the hub side (22). First of all, a bearing (30) is bedded onto said bearing side (21 ) of the planet gear pin (20). In the preferred embodiment of the present invention, said bearing (30) is a roller bearing. Planet gear (40) is positioned onto the roller bearing. There is a front washer (50) rested onto the bearing (30) in the planet gear (40). By means of an inner snap ring (60) positioned on said front washer (50), the removal of the bearing (30) and the planet gear (40) is prevented. There is an inner snap ring channel (24) on the planet gear pin (20). Said inner snap ring (60) is placed and fixed to said inner snap ring channel (24). By means of this, the bearing (30) and the planet gear pin (20) are fixed on the bearing side (21 ) section. There is a channel (12) structure on the inner wall of the pin housing (1 1 ) on the hub side (22) of the planet gear pin (20). An outer snap ring (70) is placed into said channel (12). At the same time, said outer snap ring (70) is rested onto a front surface (23) of the planet gear pin (20).

An axial movement (A) is defined where the bearing (30) and the planet gears (40) make rotation. In said axial movement (A), the planet gear pin (20) is fixed. The outer snap ring (70) is used in order to provide resistance against the forces coming in direction of axial movement (A). The outer snap ring (70) prevents the outwards sliding movement of the planet pin along the axial movement (A).

The operation of a hub (10) embodiment, whose details are given above, is as follows:

The sun gear (80) basically rotates the planet gears (40) in the front axle shaft and rear axle shaft hubs (10) of construction equipment and tractors. The planet gear pins (20) realize bearing of the planet gears (40). While the wheels are rotating, the planet gear pins (20) are subjected to an outwards axial load and they may realize axial movement (A). The axial movement (A) can be defined as an outwards sliding movement. The use of planet gear pin (20), having the same sizes, in the hubs (10) of vehicles, having engines which operate in different horse powers, becomes possible thanks to the placement of outer snap ring (70) positioned inside the channel (12) on the hub side (22). Thanks to the outer snap ring (70), the planet gear pin (20) is seated to the hub (10) in a suitable manner, and the axial movement (A) can be prevented. Thus, the axial load is absorbed by means of the outer snap ring (70).

Thanks to the subject matter hub (10) embodiment, the movement is eliminated which may occur axially outwardly due to the axial loads occurring as a result of reasons like various user errors and/or during operation of the planet gear pins (20) existing in the hub (10) provided in the axle shafts of particularly construction equipment and tractors. Under outwards axial forces which may occur; force transmission is provided to the outer snap ring (70) provided behind the planet gear pin (20), and the effect of this force can be prevented as much as the resistance of the outer snap ring (70) and the inner snap ring (60) permit, and the abrasions and damages which may occur afterwards can be prevented.

The protection scope of the present invention is set forth in the annexed Claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
