Abstract

FIELD: transport engineering; car bodies. SUBSTANCE: lower portion of car body has outer and inner parts of sill 3 of floor 4 rigidly interconnected by flanges along mating outline of both parts and are connected with floor 4. Horizontal footstep 6 and longitudinal vertical wall connected with footstep by its lower edge are made on outer part 1 of sill 3. Stiffening members 9 are installed at edges of vertical wall. Members are connected by lower edge with footstep and change into pillars of body 10 in their upper portion. Trough-shaped cavity is made in inner part. This cavity is pointed towards outer part 1. Bottom portion of trough is rigidly coupled with lower part of longitudinal vertical wall. EFFECT: simplified design, improved adaptability to manufacture, reduced weight at preservation of sufficient strength and rigidity at twisting and bending. 2 cl, 2 dwg

Claims (1)

The invention relates to a transport mechanical engineering, namely to car bodies. The objective of the invention: to simplify the design, improve its manufacturability, reduce weight while maintaining sufficient strength and rigidity in the process of working on torsion and bending. The lower part of the car body contains the outer 1 and inner parts of the threshold 3 of the floor 4, which are rigidly interconnected by flanges, along the mating contour of both parts and connected to the floor 4. At the same time, on the surface of the outer part 1 of the threshold 3 there is a horizontally located step 6 and connected with it, with its lower edge, is a longitudinal vertical wall, along the edges of which there are reinforcing elements 9, also connected by their lower edge to the substrate 6, passing in their upper part into body racks 10. In the inner part 2 there is a trough-like recess facing toward the bottom of 1 and rigidly connected by its bottom to the bottom of the longitudinal vertical wall 8.
