A BODY SIDE ENGINE MOUNTING BRACKET
TECHNICAL FIELD
[0001] The present disclosure, in general, relates to a powertrain mount used in vehicle. In particular, the present disclosure relates to a powertrain mount which is installed between a powertrain such as an engine or transmission of a vehicle and the vehicle structure such as a sub-frame where the powertrain is installed and supported, to thereby isolate vehicle vibration from being transmitted between the powertrain and the vehicle structure.
BACKGROUND OF THE INVENTION
[0002] Vibration inside the vehicle is one of the major concerns that need to be solved nowadays. Vehicle vibration occurs in a wide range of frequencies from low to high frequency bands. The vibration may be transmitted to the vehicle body externally from the road surface via the tire and suspension equipment or internally from the engine via the operating system.
[0003] When a vehicle is stopped, idle rotation of the engine produces so called idle vibration, due to fluctuation in torque caused by fuel combustion inside the engine. Such engine vibration is transmitted through the steering wheel to driver's hands, or to car seats and passengers. At this time, the vibration being transmitted varies with vibration level due to the engine state and vibration transmission characteristics of the vehicle body. According to the vibration transmission characteristic, often the vibration frequency being transmitted matches with inherent frequency of the structure of vehicle, the deck cross member, the steering wheel and the muffler to cause resonance, leading to an increased level in the idle vibration.
[0004] While traveling at a constant speed on a bumpy road or an unpaved road, the entire vehicle bounces up and down, and experiences rolling and pitching, along with the engine vibration. Resonance between the suspension and the vehicle body results in significant wobbling of the vehicle.

[0005] In order to prevent this resonance and isolate vibration transmission between vehicle components such as a powertrain and a sub-frame on which the powertrain is mounted, many attempts have been made. For example, relevant components may be designed to have inherent vibration frequencies different from that of engine vibration, or isolation may be provided in the vibration transmission passageway. The present disclosure is directed to the latter approach.
[0006] A powertrain mount provides a major transmission path through which vibration generated in the powertrain is transmitted to the vehicle body, and thus has significant effects on the idle vibration. Mounting type is categorized into principal axes of inertia type and gravity center type, depending upon support modes thereof, and into 3-points mounting type and 4-points mounting type, depending upon the number of mountings.
[0007] Generally, the mounting insulators include a rubber type and a liquid-type sealed with rubber. The present disclosure is related to the former.
[0008] The existing body side bracket has biggest disadvantage that they fails to overcome the stresses generated. Hence, there is a need of body side bracket that efficiently withstand the increased stresses ensuring minimum vibration transfer to body panel.
OBJECTS OF THE DISCLOSURE
[0009] Some of the objects of the present disclosure, which at least one embodiment herein satisfy, are listed here in below.
[0010] It is a general or primary object of the present disclosure to provide a body side bracket for mounting a powertrain on a structural body of a vehicle that effectively withstand increased stresses ensuring minimum vibration transfer to the body panel.

As shown in the fig, the power train 1000 is mounted over the bracket 100 which is attached with the body side bracket 200 through a link 300. The power train produces lot of vibration,

which in turn produces high amount of stresses that are transferred to the body side bracket and make it weak. Hence, there is need to change the configuration of the body side bracket through which the stress bearing capacity increases.
