DESC:The present disclosure generally relates to a modular suspension system and method of manufacturing thereof. More particularly, the present disclosure relates to the modular suspension system designed without torque rod. Further the slipping ends of modular suspension system designed in such way to avoid maintenance points and same springs used at all four positions.
[002] In commercial vehicle, load articulation in multi-axle truck is achieved through bell-crank lever mechanism. Further existing bell-crank system, there are 20 maintenance(greasing) points. Such 20 maintenance(greasing) points amounts to increased maintenance in system. Further conventional solution to above problem is bringing system having two maintenance points, which may lead to higher cost due to the torque rod system.
[003] There are two types of conventional solution. The first one is fully slipper suspension comes with four torque rods mounted to align the axles. It has two maintenance points at center of the axles. The another is semi-slipper suspension system. This system has two torque rods to align the rear axle, where the front axle is aligned with the help of mounting eye with hanger brackets.
[004] Therefore, there is an unmet need to develop a cost-effective user-friendly modular suspension system to eliminates need of torque rods to align and hold the axles. Therefore, the benefits of system present invention is to minimize the maintenance points to decrease the maintenance cost substantially.
[005] The present invention relates to a modular suspension system and method of manufacturing thereof. More particularly, the present disclosure relates to the modular suspension system designed without torque rod. Further the slipping ends of modular suspension system designed in such way to avoid maintenance points and same springs used at all four positions.
[006] The present subject matter discloses a modular suspension system for heavy vehicle comprises atleast one springs with hanger brackets at front and rear ends of the mainframe of the vehicle and atleast one greasing points, wherein articulation takes place by means of center balancing characterized by eliminating torque rods to align and hold the axles and lowers weight of middle bracket thus reducing system weight in totality.
[007] In another embodiment, the modular suspension system for heavy comprises four springs with hanger brackets at front and rear ends of the mainframe of the vehicle. Here the nature of spring is leaf spring. The spring is integrated to first axle integrated with second axle to maintain the front and rear half spans of leaf springs same.
[008] The modular suspension system for heavy vehicle further comprises six greasing points, wherein articulation takes place by means of center balancing system in addition to six maintenance point as compared to conventional twenties maintenance point.
[009] The present invention discloses the modular suspension system comprising six greasing points, wherein articulation takes place by means of center balancing system.
[0010] To illustrate the further invention in detailed manner, the modular suspension system comprising four springs with hanger brackets at front and rear ends of the mainframe of the vehicle. Further the leaf springs from first axle integrated with second axle to maintain the front and rear half spans of leaf springs same. This is not possible in other suspension systems.
[0011] Unlike existing suspension, the modular suspension system of present invention eliminates torque rods and lowers weight of middle bracket thus reducing system weight whole.
[0012] The present subject matter tried to eliminate the shortcomings of existing system and increase its acceptance through offering better ride comfort and eliminating maintenance requirements. The system of present invention is designed in such a way to eliminate the use of torque rods and thus reducing the cost of the system. Here the typical torque rod costs around 3000-4000 per piece. Also, the weight of middle hanger is reduced, thus reducing the cost of the system.
[0013] Further the present system reduces the maintenance costs as compared to conventional multi-axial system suspension reduces maintenance points by 70% from existing Bell crank. The design of present invention comprising 6 maintenance points as compared to 20 maintenance points in bell crank system, thereby reduction of 70% maintenance cost for the system.
[0014] Although the present disclosure is described in terms of certain preferred embodiments and examples, other embodiments and examples will be apparent to those of ordinary skill in the art, given the benefit of this disclosure, including embodiments and examples that do not provide all of the benefits and features set forth herein, which are also within the scope of this disclosure. It is to be understood that other embodiments may be utilized, without departing from the true spirit and scope of the present invention.
[0015] It is to be understood that other embodiments of the present disclosure will become readily apparent to those skilled in the art from the following detailed description, wherein it is shown and described only various embodiments of the disclosure by way of illustration. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.
[0016] It would become abundantly clear to a person in the art, after reading this specification that the present subject matter also provides a modular suspension system and method of manufacturing thereof. More specifically, the present subject matter discloses a modular suspension system characterized by eliminating torque rods to align and hold the axles and lowers weight of middle bracket thus reducing system weight in totality without departing from the spirit of the present subject matter. While the subject matter may be susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and have been described herein. Alternate embodiments or modifications may be practiced without departing from the spirit of the present subject matter. The drawings shown are schematic drawings and may not be to the scale. While the drawings show some features of the subject matter, some features may be omitted. Alternatively, in some other cases some features may be emphasized while others are not. Further, the methods disclosed herein may be performed in manner and/or order in which the methods are explained. Alternatively, the methods may be performed in manner or order different than what is explained without departing from the spirit of the present subject matter. It should be understood that the subject matter is not intended to be limited to the particular forms disclosed. Rather, the subject matter is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the subject matter.
