Lightweight stamping and welding type automobile engine suspension support

Abstract

The invention discloses a lightweight stamping and welding type automobile engine suspension support. The lightweight stamping and welding type automobile engine suspension support comprises a flat support body and an auxiliary support which is connected with the side edge of the support body by adopting stamping and welding, wherein the support body is provided with a hole which can be used for suspending an engine on the support body; the auxiliary support is divided into an upper section, a bending part and a lower section, the upper section and the lower section are connected through the bending part, and the bending angle of the auxiliary support is 90-135 degrees. According to the lightweight stamping and welding type automobile engine suspension support disclosed by the invention, stamping and welding of plates is adopted, compared with conventional cast iron manufacturing, the design, the disassembly and the assembly are convenient; lightweight requirements are met as the automobile engine suspension support is manufactured by adopting stamping and welding of metal plates of aluminum alloy, nickel alloy and the like which are in less mass and enough strength; low-cost development requirements of the automobile engine suspension support can be met on the premise that the load of weight of the engine is ensured to be borne by adjusting the size of the auxiliary support if the type of the engine is changed, NVH (Noise, Vibration and Harshness) characteristics of an automobile are facilitated to be stabilized, and dynamic / static state strength and fatigue life of the lightweight stamping and welding type automobile engine suspension support are prolonged.

Description

technical field [0001] The invention relates to a bracket, in particular to a lightweight stamping and welding type automobile engine suspension bracket, which belongs to the technical field of automobile manufacturing. Background technique [0002] The engine of the automobile powertrain is the core part of the automobile, and its performance is directly related to the safety and comfort of the automobile. The main function of the automobile engine mount bracket is to connect the powertrain and the body, bear the weight of the powertrain under various working conditions, and at the same time reduce the vibration excitation transmitted from the powertrain to the body, which not only greatly affects the vibration and noise of the vehicle impact, and has a huge impact on vehicle safety. [0003] At present, most of the engine brackets are castings. Although they can meet the strength requirements, they have a large mass, which is not conducive to weight reduction and conforms...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the engine brackets are castings. Although they can meet the strength requirements, they have a large mass, which is not conducive to weight reduction and conforms to the current development trend of automobile lightweight; if the engine model changes, the weight of the engine will increase, and the engine torque output increase, which requires the suspension bracket to carry a greater load, and the redesign scheme requires another mold, which further increases the manufacturing cost
