CAR BODY FRAME Russian patent published in 2018 - IPC B62D25/00 B62D23/00 

FIELD: machine engineering.

SUBSTANCE: invention relates to the field of transport machine engineering. Car body frame contains a spatial frame made of load-bearing elements made of metal profiles and forming the front part of the frame, a rear part of the frame and side structures. Front part of the frame includes lower and upper structures connected by load-bearing elements, each of which includes longitudinal and transverse load-bearing elements forming a engine compartment of the frame. Rear part of the frame includes a back wall and a lower structure connected to it. Side structures connect the front and rear parts of the frame, and also form a propeller tunnel. Propeller tunnel is located between the side structures and is connected by load-bearing elements to the front and rear parts of the frame. Central planes of the engine compartment of the frame and the propeller tunnel are offset from a central vertical plane of the frame.

EFFECT: improvement in car weight distribution along the longitudinal axis is achieved.
