Lower vehicle body and vehicle body skid positioning method

Abstract

The invention relates to a lower vehicle body and a vehicle body skid positioning method.The lower vehicle body comprises an engine compartment edge beam rear section outer lining plate and a rear floor edge beam middle section, and is characterized in that a punching area is formed in the part of the engine compartment edge beam rear section outer lining plate, and a plurality of front skid positioning holes sequentially formed in the X direction can be formed in the punching area; the middle section of the rear floor boundary beam is provided with at least two rear skid positioning holes which are arranged at intervals in the X direction, and the connecting line of the centers of the front skid positioning holes and the centers of the rear skid positioning holes extends towards the X direction. The structure for installing and positioning the skid is stable in supporting, can meet the requirements of vehicle types with different axle distances under platform planning and can also adapt to different sizes of the skid in various production bases, and the development cycle and cost of the whole vehicle are reduced to a certain extent.

Description

technical field [0001] The invention relates to the technical field of automobile engineering, in particular to vehicle body technology. Background technique [0002] Due to the different skid tooling between the production bases, the position and spacing of the skid positioning holes of the vehicle models in different bases are different. At the same time, due to the different wheelbases of various models, the installation and positioning structures of the body skids of each vehicle model are different, and platformization cannot be realized; and Due to the different structure of the installation and positioning parts of the body skids of each model, the part tooling of each model cannot be used in common, resulting in high costs of parts and complete vehicles. With the advancement of the platformization of various car companies and the increasing cost pressure. Contents of the invention [0003] One of the purposes of the present invention is to provide a lower body to ...
