, Description:TECHNICAL FIELD
The embodiment herein generally relates to a parallel link bracket assembly. More specifically, the invention relates to a parallel link bracket assembly in an air suspension system of an automobile.
BACKGROUND AND PRIOR ART
Automobiles are provided with a suspension system for improving ride handling and imparting comfort. The suspension system helps in maintaining contact between tires of a vehicle and the road surface and evenly balancing weight of the vehicle. Improper and uneven road conditions generate forces on the vehicle, and the effect of these forces are dampened and absorbed by components of the suspension system.
Generally, heavy commercial vehicles such as Buses, trucks, trailers use an air suspension system as it provides better support in variable road conditions. Components of the air suspension system include parallel link brackets which are used for supporting parallel link assembly. The parallel link brackets endure loads due to many forces such as braking, driving, cornering and other factors. The design of a parallel link bracket is crucial for reducing stresses, imparting strength and thereby increasing the life of the parallel bracket assembly. The life of the parallel link brackets in turn improves the performance of the air suspension assembly.
Therefore, there is a need for a parallel link bracket assembly in an air suspension system of an automobile. In particular, there is a need for a parallel link bracket assembly in an air suspension system of an automobile having higher strength and reduced stresses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The embodiments and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments. The examples used are intended merely to facilitate an understanding of ways in which the embodiments may be practiced and to further enable those of skill in the art to practice the embodiments. Accordingly, the examples should not be construed as limiting the scope of the embodiments.
As mentioned above, there is a need for a parallel link bracket assembly in an air suspension system of an automobile. In particular, there is a need for a parallel link bracket assembly in an air suspension system of an automobile having higher strength and reduced stresses. The embodiments achieve this by providing a parallel link bracket assembly of a vehicle suspension unit. Referring now to the drawings, and more particularly to Figs. 1 through 4, where similar reference characters denote corresponding features consistently throughout the figures, there are shown preferred embodiments.
Fig.1 illustrates a schematic diagram of a perspective view of a parallel link bracket assembly in an air suspension system, according to an embodiment. The parallel link bracket assembly 100 in an air suspension system comprises of a main pressing part 101, stiffeners 102, a box pressing part 103, a link channel bracket 104.
In an embodiment, the stiffeners 102 are fixed at both sides of the main pressing part 101.
Fig.2 illustrates a schematic diagram of a side view of the parallel link bracket assembly in an air suspension system, according to an embodiment.
In an embodiment, the stiffener 102 includes a main stiffener 201 and a side stiffener 202. The main stiffener 201 has a width 204, a length 205. In an embodiment, a profile of the side stiffener 202 is an arc 203. An angle of the arc is in the range of 90 degrees to 110 degrees. In an embodiment, length of the arc 203 is in the range of 120 mm to 130 mm. In an embodiment, radius of the arc 203 is in the range of 80 mm to 90 mm. The stiffeners 102 having the arc 203 profile can withstand up to 3,00,000 Cycles in rig testing for a vertical load of 2.5g.
In an embodiment, a gap in the range of 0.3 mm to 0.5 mm is present between the main stiffener 201 and the side stiffener 202. The gap in the range 0f 0.3 mm to 0.5 mm increases weld penetration, thereby increasing strength of the stiffener 102.
In an embodiment, the width 204 of the main stiffener is in the range of 400 mm to 420 mm. The length 205 of the main stiffener is in the range of 320 mm to 330 mm.
