Description

Structure preventing piston deformation in commercial vehicle suspension systems
TECHNICAL FIELD
The present invention, in general relates to the suspension systems of the commercial vehicles.
The invention particularly relates to threaded damping disc and threaded fixing part structure preventing deformation that may occur in the piston in the suspension systems.
STATE OF THE ART
Today, suspension systems are used to minimize the effects that the vehicles are exposed to on road conditions. The suspension systems that are used in the commercial vehicles generally consist of bellows that provide the suspension function, a damper that connects the suspension system to the vehicle, and a piston that provides the connection between the bellows and the damper. There is a damping bumper that is connected to the damper shaft and the bellows together, providing the damping function.
There is a space between the piston and the damper in the suspension systems in the state of the art. The damping bumper connected to the damper shaft contacts the piston due to said space, during the damping process of the suspension system. Deformation may occur in the piston during this contact. This situation may cause the suspension system not to fulfill its function properly.
In the state of the art, a damper module is encountered in the document numbered EP1831583B1. There is a space between the piston and the damper as can be seen in said damper module. It is possible that the damping bumper may hit the piston and deform the same during the damping process of the suspension system due to this space.
As a result; developments are made in the suspension systems used in the commercial vehicles, therefore new configurations are required in order to eliminate above mentioned disadvantages and bring solution to current systems.
AIM OF THE INVENTION
The present invention is related to a suspension system which fulfills the above mentioned requirements, eliminates all disadvantages and brings some additional advantages.
The main aim of the invention is to prevent the damping bumper from contacting the piston and the risk of deforming the piston as a consequence of this contact during the damping process in the suspension systems used in commercial vehicles. A damping element is used in the upper part of the damper so as to meet the damping bumper.
In order to realize all the advantages mentioned above and which will be understood from the detailed description below, the present invention is a suspension system comprising a damper that provides the realization of the suspension function in the commercial vehicles and enables the suspension system to be connected to the vehicle, bellows that provides damping function within the suspension system, a piston that connects the damper to the bellows and a damping bumper that is connected to the bellows and connected to the damper shaft; and a structure is obtained comprising the following;
• a threaded damping disc that is located at the upper part of the piston inside the bellows and between the piston and the damper, meets the load coming from the damping bumper and
• threaded fixing part that is located on the damper and provides fixing the threaded damping disc to the damper. The structural and characteristic features of the present invention will be understood clearly by the following drawings and the detailed description made with reference to these drawings. Therefore the evaluation shall be made by taking these figures and the detailed description into consideration.
BRIEF DESCRIPTION OF DRAWINGS
In order to understand the advantages of the present invention with its structure and additional elements, it shall be evaluated with the following defined figures.
Figure 1 is a sectional view of the inventive suspension system.
Figure 2 is a detailed view that shows the connection of the damper with the threaded damping disc and the threaded fixing part in the inventive suspension system.

DETAILED DESCRIPTION OF THE INVENTION
In this detailed description, the preferred embodiments of the inventive suspension system is described only for clarifying the subject matter in a manner such that no limiting effect is created.
The present invention is a suspension system comprising a damper (1 ) that provides the realization of the suspension function in the commercial vehicles and enables the suspension system to be connected to the vehicle, bellows (3) that provides damping function within the suspension system, a piston (2) that connects the damper (1) to the bellows (2) and a damping bumper (4) that is connected to the bellows (3) and connected to the damper (1 ) shaft; also comprising the following; • a threaded damping disc (5) that is located at the upper part of the piston (2) inside the bellows (3) and between the piston (2) and the damper (1 ), meets the load coming from the damping bumper (4) and
• a threaded fixing part (6) that is located on the damper (1) and provides fixing the threaded damping disc (5) to the damper (1).
Figure 1 is a sectional view of the inventive suspension system. In said suspension system, as mentioned earlier, the threaded damping disc (5) is connected on the piston (2) and between the piston (2) and the damper (1) so as to meet the damping bumper (4). Thus, the damping disc (5) meets the loads coming from the damping bumper (4) and provides the damping of this load. Thus, the load coming from the damping bumper (4) is prevented from directly affecting the piston (2).
In Figure 2, there is a detailed view showing the connection of the threaded damping disc (5) to the damper (1). The threaded damping disc (5) is connected to the damper (1 ) in the position where it is positioned. A threaded fixing part (6) is used so as to fix the threaded damping disc (5) to the damper (1) in order to provide this connection. Said fixing part (6) is preferably in a threaded form in accordance with the threaded dampers (1).
It is provided to fill the space between the piston (2) and the damper (1) with a threaded damping disc (5) and the loads coming from the damping bumper (4) are met with this threaded damping disc (5) by means of the inventive structure. Thus, deformation of the piston (2) is prevented and its function is provided properly.
