Specification

Description:INTERMEDIATE ENGINE MOUNTING BRACKET STRUCTURE
TECHNICAL FIELD
[0001] The present disclosure, in general, relates to a bracket structure and more particularly to an intermediate engine mounting bracket structure to hold a transmission case and an engine mount.
BACKGROUND

[0002] Traditionally, an engine mount carrying an engine and a transmission case in a vehicle are attached to a holding bracket. The engine mount is mounted on the holding bracket at one end, and the transmission case is attached on to another end of the holding bracket through various fixing points. The fixing points are present in the holding bracket such that the transmission case is attached in a water line direction. Some holding brackets include another fixing point at a point to attach the transmission case in a buttock line direction along with various fixing points in the water line direction. Although the transmission case is attached through multiple fixing points, there may be a possibility that the alignment and balance of the transmission case may not be accurate while being attached to the holding bracket.
[0003] Further, when the vehicle is in a dynamic motion, vibrations are generated that may flow from a powertrain to the passenger cabin via the holding bracket and an engine mount. To counter the vibrations such that the holding bracket does not get in resonance with the engine mount and transfers the vibrations to the passenger cabin, the holding bracket is provided with ribs to absorb the vibrations. However, the number of ribs currently present in the holding brackets are successful in absorbing the vibrations to some extent.
[0004] Fig. 1a illustrates a diagram 100a depicting a holding bracket 102a to receive an engine mount and a transmission case, in accordance with an existing prior art. The holding bracket 102a may receive the engine mount on an upper surface and the transmission case at a lower surface through various mounting holes. The transmission case is attached through fixing points in a buttock line direction along with various fixing points in a water line direction.
[0005] Fig. 1b illustrates a rear view diagram 100b of the holding bracket 102a, in accordance with an existing prior art. A lower side of the holding bracket includes horizontal ribs to absorb vibrations generated from a powertrain mounted on the holding bracket.
[0006] There is a need for a solution to overcome above mentioned drawbacks.
