Description
A CAMBER LINK COMPRISING LATERAL DAMPER
Technical Field
The present invention relates to a camber link comprising a lateral damper for adjusting the camber angle positioned between traverse and axon, and required for the vehicle to turn a bend safely.
Background of the Invention
Camber links are used in rear suspension systems which are a sub-part of the chassis system. Camber links are structural parts and they controls the camber angle of the rear axle of the vehicle. Camber links are used between the traverse and the axon in order to keep the drive, comfort and road-handling properties at the highest level, particularly in fully independent suspension systems. Camber links are parts with a high-rigidity value produced by means of forging method in order to provide the camber angle required for enabling the vehicle to turn a bend safely. It is important to adjust the camber angle properly so that the vehicle can turn a bend safely. The camber angle enables to turn a bend in a safe way, by enhancing the wheel’s contact with the road while the vehicle turns a bend. If no negative camber occurs in the rear tires particularly while turning a bend, it is possible for this angle to turn positive and the road-handling to decrease. In addition, the fact that the camber angle is not adjusted properly leads to irregular wheel wears which reduce the customer satisfaction. In the prior art, the camber connection angle is adjusted by means of a rigid camber link so as to remain within a fixed value range and it is not possible to obtain a variable camber angle with the said camber link particularly while the vehicle is dynamic, according to changing road and load conditions. Therefore, today there is need for a camber link which allows more extension and shortening motion according to changing
load conditions, instead of a camber link obtained by means of forging method with a high rigidity value.
The Chinese utility model document no. CN207274773U, an application included in the state of the art, discloses a connection structure for providing real-time control of the camber angle made by wheels in the rear suspension of a vehicle. A camber angle connecting rod, a connecting rod hydraulic cylinder, a driving hydraulic cylinder are used in the said utility model document, in order to provide the real-time adjustment of the camber angle of a wheel included in the rear suspension of a vehicle. The connecting rod is driven hydraulically by performing the connection of the camber connecting rod, the connecting rod hydraulic cylinder with the piston rod in a fixed way. In the said utility model, adjustment of the wheel camber angle is performed by changing the length of the camber link - which is included in the suspension-hydraulically. The said camber angle can be reduced or increased by performing the drive of the connecting rod hydraulically.
Summary of the Invention
An objective of the present invention is to realize a camber link comprising a lateral damper which enables to allow extension and shortening motions according to changing load conditions.
Another objective of the present invention is to realize a camber link which ensures a drive to be safe and comfortable by allowing a higher camber angle in hairpin bends whereas a lower camber angle in bends with lower radius, by means of a lateral damper.

The inventive camber link (1) for allowing extension and shortening motions according to changing load conditions comprises at least one lateral damper (2) which is connected to the traverse (T) from its one end and to the axon (A) from its other end, and enables to adjust the camber angle by performing a stretching motion between the axon (A) and traverse (T) connection depending on the changing load conditions of the vehicle; and a plurality of connection members (3) which provide the axon (A) and traverse (T) connection of the damper (2).
The lateral damper (2) included in the inventive camber link (1) performs extension and shortening motions depending on the changing load and road conditions and it enables the vehicle to move at the most optimum camber angle. The lateral damper (2) ensures a safe drive by enabling the wheels to contact the road further, by means of the extra angle provided to the wheels while the vehicle turns a bend.
The lateral damper (2) is a precision damper with hydraulic flow used to enhance cabin comfort of heavy commercial vehicles in particular. The lateral damper (2) performs an adjustment by responding to the mechanical displacement of the hydraulics within a tube for the variable force values received by the related location while turning a bend.
The connection member (3) included in the inventive camber link (1) is a screw nut duo. There are connection apertures where the connection member (3) can pass through in the lateral damper (2) and the pieces of traverse (T) and axon (A) where it is connected. Connection of the lateral damper (2) is realized by means of the connection members (3) which are passed through the said connection apertures.
With the inventive camber link (1), it is ensured to travel in the vehicle always at the most optimum camber angle due to the fact that the vehicle is at a higher camber angle in hairpin bends whereas it is at a lower camber angle in bends with lower radius, depending on the changing load and road conditions. By adjusting the camber angle automatically according to different load conditions and providing a drive at the most optimum level with the inventive camber link (1), irregular wheel wears are reduces and the customer satisfaction is kept at maximum level.
