Problems solved by technology

The Y-direction dynamic stiffness of the engine mount is the main force direction of the engine. Especially for low-end and mid-range cars, due to the engine itself, the Y-direction dynamic stiffness of the mount is very small, which often cannot meet the design requirements, causing serious consequences in accidents. Serious consequences for life and property

Abstract

The invention provides a car body side structure for increasing engine suspension Y-direction dynamic stiffness. The car body side structure comprises a suspension right side car body structure, a suspension left side car body structure and a longitudinal beam connecting plate. The suspension right side car body structure comprises a longitudinal beam web B, a right side suspension support, a fender guard, a right side wheel cover plate and a vertical plate. The suspension left side car body structure comprises a longitudinal beam web A, a fender guard, a left side suspension support and a left side wheel cover plate. The suspension right side car body structure and the suspension left side car body structure are each provided with a wheel cover reinforcing plate used for reinforcing connection rigidity. One wheel cover reinforcing plate is arranged between one fender guard and the right side wheel cover plate, and the other wheel cover reinforcing plate is arranged between the other fender guard and the left side wheel cover plate.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a body side structure for increasing the Y-direction dynamic stiffness of an engine mount. Background technique [0002] Mounts are used to reduce and control the transmission of engine vibration and play a supporting role in automotive powertrains. They are used in the current automotive industry. The widely used mounts are divided into traditional pure rubber mounts, and dynamic and static mounts. Hydraulic mount with better performance. [0003] Dynamic stiffness is the ability of the structure to resist deformation under dynamic disturbance, and the structural deformation ability of unit excitation within 20-200Hz. The Y-direction dynamic stiffness of the engine mount is the main force direction of the engine. Especially for low-end and mid-range cars, due to the engine itself, the Y-direction dynamic stiffness of the mount is very small, which often cannot meet the desi...
