DESCRIPTION

A BUSH WITH BALL PIN

Technical Field

The present invention relates to a bush which is particularly used in suspension systems of vehicles, enables interconnection of structural parts of vehicles mechanically, has a plurality of spring pins, is driven into the bearing where it will fit into by means of a spring pin, and is prevented from being separated from the bearing upon it fits into the holes located corresponding to the pins.

Background of the Invention

Bushes adjustable according to according to the dynamics of the vehicle are used in suspension systems, which is a sub-part of the chassis system in vehicles. The said bushes realize interconnection of structural parts, which are included not only in the suspension system but also in other areas of the vehicle, mechanically. With this connection, they function as a vibration and shock absorber, load carrier and/or transmitter. Bushes also prevent abrasions and noises that may occur on the basis of friction in connections they make with the principal load carriers.

Today, in the event that bushes particularly utilized in suspension systems are used beyond vehicle limits, they are exposed to high loads and wear due to friction and/or dynamic loads. As required by operating logic of bushes, they must be driven into a bearing by means of shrink-fit at the step of interconnection of two different metal parts. It is expected that the bush and its bearing, which are nested together, do not disconnect in cases where the vehicle is exposed to high loads and the rubber parts used in the bush-bearing connection are expected fulfill their long-term duties. However, the bush begins to move within the bearing both because of high loads and due to the fact that rubber parts fail to fulfill their duty after a certain period of time. This situation leads to attenuation of mechanical connection and also causes the mechanical connection to disconnect or noise to occur.

Therefore, in the state of the art, there is need for a suspension bush which prevents bushes from being separated from the bearing based on abrasion of the connection -that is performed in the structural parts used particularly in suspension systems- and/or dynamic loads and enables to avoid vibration and noise depending on time.

The Korean patent document no. KR20110062009, an application included in the state of the art, discloses a bush mounting structure. With the said bush mounting structure, it is aimed to ensure replacement of bushes easily and to enhance the durability of a bush by decreasing the load applied to the bush. Therefore, the bush configuration -which is subject to the Korean patent document- comprises a bush bearing, a bush and a structure which will enable the bush to rotate on the bush bearing. A protrusion is included on the bush so that the bush can rotate on the bush bearing and a guide slot wherein the protrusion will get in is included on the bush bearing. It is also disclosed in the Korean patent document that the protrusion has a mobile structure on the bush and it is pushed towards the bush bearing by means of a spring included in the slot.

The Korean patent document no. KR20170077958 A, another application included in the state of the art, discloses a coupled torsion beam axle for vehicles. It is disclosed that the said torsion beam comprises a bush and a mounting bearing wherein the bush is embedded, in addition to multiple components it has. The mounting bearing comprises at least one mounting hole and the said mounting holes are inserted into designated protrusions. Thereby, the bush is fixed to the bush bearing. Elastic members are included in the openings where the protrusions are located on the bush in order that the protrusions, which are included on the bush, can be pushed towards the bush bearing. Summary of the Invention

An objective of the present invention is to realize a bush which is used in suspension systems of vehicles, enables interconnection of structural parts mechanically, has a plurality of spring pins, is inserted into the bearing where it will fit into by means of the said spring pin, wherein locking is performed upon it fits into the openings located corresponding to the pins, and whereby it is prevented from being separated from the bearing.
