Specification

Description: A BRAKE HOSE ASSEMBLY STRUCTURE FOR A VEHICLE TECHNICAL FIELD The present subject matter described herein, relates to a brake hose assembly structure for a vehicle to provide linear and rotational positions with respect to front suspension. More particularly, the present invention relates to a support structure assembly of the brake hose assembly structure of the vehicle to obtain linear and rotational positions of the brake hose. BACKGROUND Background description includes information that may be useful in understanding the present subject matter. Generally, in automotive, a brake hose is a flexible hydraulic hose that is fitted in between chassis which is vehicle body and brake calipers. The flexible hydraulic brake hoses allow passage of hydraulic brake fluid to wheel brakes. In order to cater steering and suspension movements in dynamic condition, it is required to bend and route the hydraulic brake hoses around its surrounding parts. To effectively and protectively route the brake hose to the disc brake caliper of wheel assembly by ensuring proper clearance between the brake hose and other components of the vehicle, the brake hose is connected to the front suspension. To achieve the effective and clear routing of the brake hose, the hydraulic brake hose is provided with a brake hose support bracket which is adapted to be fixed to a vehicle part, such as a suspension component or wheel assembly. The brake hose support bracket is fixed to the strut assembly of the suspension so that an intermediate portion of the brake hose does not contact the vehicle body or the wheels or entangled while bump or full rebound of the vehicle. Disadvantage associated with the existing brake hose support bracket structure is that the support bracket structures fixes the position of the brake hose structure and does not allow movement or rotation of the brake hose once the bracket is fixed by way of bolting or welding. However, the brake hose support bracket structure or hose supporting structure makes the brake hose structure a fixed type structure with respect to the strut assembly or damper assembly or wheel assembly. Once the brake hose is mounted, there is no possibility to tweak or rotate the brake hose. Therefore, even during the design and testing of the vehicle, several brake hose pipes with different orientations are required. For example, if position of the brake hose pipe is not appropriate or facing failure during testing, another brake hose pipe is to be manufactured as per the modifications and tested again in the vehicle. Upon final testing of the vehicle, final design of the brake hose pipe is decided. Therefore, during testing and development of the vehicle, a plurality of brake hose pipes are required which increases the cost and the turn-around time. Further, dis-assembly and assembly of another brake hose pipe also consumes time. As shown in fig. 1, the brake hose 102 defines a longitudinal structure defining a first end 106 and a second end 108 where a supporting structure 104 is disposed in between the first end 106 and the second end 108 to affix the brake hose 102 on a strut assembly or front suspension base 110. The supporting structure 104 is permanently fixed on the cylindrical shape of the brake hose 102. When the supporting structure 104 is fixed or joined with the strut assembly or front suspension base 110, it is not possible to move or rotate the brake hose 102. Therefore, there is a need to provide a simple and cost-effective solution which can allow linear and/or rotational movement of the brake hose while affixing with the strut assembly or front suspension base 110. OBJECTS OF THE DISCLOSURE In view of the foregoing limitations inherent in the state of the art, some of the objects of the present disclosure, which at least one embodiment herein satisfy, are listed herein below.
