FIELD: transportation; machine building.
SUBSTANCE: group of inventions relates to the field of transport machine building. In the first embodiment, the vehicle lower portion design contains a pair of thresholds and the electric power supply device. Thresholds pass in the vehicle longitudinal direction and are placed on the floor panel both outer sides in the vehicle transverse direction. Electric power supply unit is located under the floor panel. Thresholds include the outer portion, the inner portion and the shock absorption portion. Shock absorption section passes in the transverse direction from the outer section to the inner section, and covers the electric power supply device. According to the second embodiment, the vehicle lower portion design contains a transverse floor element, located between the thresholds above the floor panel and a shock absorption portion. Shock absorption section covers the transverse floor element.
EFFECT: enabling reduction of the threshold folding at impact.
