CHASSIS OF COMPACT CARGO VEHICLE WITH ELECTRIC DRIVE Russian patent published in 2021 - IPC B62D21/02 

FIELD: transport machine building.

SUBSTANCE: invention relates to chassis of compact cargo vehicle with electric drive. Chassis includes frame, front and rear axles and compartment for electric energy accumulators. Accumulators represent a set of accumulator batteries located on the side of the frame bottom. Frame consists of: rear part and front part connected to it through brackets. Front part of frame is installed with lowering relative to rear part of frame. Front part of frame is made in the form of two parallel and symmetrically installed relatively to longitudinal axis of frame of short side members, on which part of floor of cabin with floor is installed, and transverse beam under base of bumper of cabin, fixed on free ends of side members. Rear part of frame is made in form of two parallel and symmetrically installed relative to longitudinal axis of frame of long side members and connecting them front, rear and two middle cross bars. Middle crosspieces are located between the front and rear axles and form a span for installation from the bottom of the frame of the compartment for electric energy accumulators. Length of span is (0.39-0.41) of the length of the rear part of the frame at constant distance between the front crossbar and the middle span crossbar nearest to it.

EFFECT: creation of unified chassis enabling to arrange vehicle with energy accumulators of different volume.
