Abstract

The invention discloses a front auxiliary frame and engine suspension connecting structure. The connecting structure comprises an auxiliary frame upper plate, an auxiliary frame lower plate, and an engine suspension arranged between the auxiliary frame upper plate and the auxiliary frame lower plate; the auxiliary frame lower plate is provided with a bolt through hole upwards vertically penetrating through an engine suspension and the auxiliary frame upper plate; a fastening bolt extending out of a bolt through hole in the auxiliary frame upper plate is inserted in the bolt through hole from bottom to top; a protecting ring surrounding a bolt head of the fastening bolt is arranged on the lower side surface of the auxiliary frame lower plate; the protecting ring includes a cylindrical vertical ring connected with the auxiliary frame lower plate; and the lower edge of the vertical ring is inwards bent to extend to form a transverse reinforcing ring, so that the cross section of the protecting ring is L-shaped. The connecting structure is simple in structure, can effectively protect the bolt head for connecting the engine suspension with a front auxiliary frame from being scratched and collided by a ground projected object in advancement or retreating of a vehicle, and facilitates improvement of the vehicle driving safety.

Description

technical field [0001] The invention relates to the vehicle body structure, in particular to a connection structure between the front auxiliary frame and the engine suspension. Background technique [0002] The front sub-frame of the car is used as an intermediate transition connection part in the load-bearing body to provide support for the engine, and disperse and transmit the impact force from the ground and the engine to the body. The engine suspension is connected to the front sub-frame by bolts from bottom to top. Between the subframe upper plate and the subframe lower plate of the frame. For example, a "front 1 frame assembly structure" disclosed in Chinese patent literature, its announcement number is CN203601381U, includes the front sub-frame body, and the front sub-frame body includes the upper half shell of the body and the lower half shell of the body , the upper half shell of the body is fixedly connected with the lower half shell of the body, and one side of t...
