FRONT PART OF VEHICLE BODY, VEHICLE BODY AND METHOD OF MANUFACTURING FRONT PART OF VEHICLE BODY Russian patent published in 2020 - IPC B62D25/08 

FIELD: transport machine building.

SUBSTANCE: vehicle front part design comprises upper longitudinal beam and upper protective beam, supporting wing of vehicle and passing parallel to upper longitudinal beam. Resistance of plastic deformation of upper protective beam increases from its front end to rear end. Upper protective beam comprises front section and rear section, in which plastic deformation resistance is higher than that of front section. Yield point of material of rear section exceeds yield point of material of front section and/or wall thickness of rear section exceeds wall thickness of front section. Vehicle body comprises said structure. Proposed method comprises fabrication of upper protective beam to make inner and outer body halves. Inner and outer halves of the housing are assembled along a longitudinal plane.

EFFECT: higher resistance to impact loads.
