Passenger car frame structure

Abstract

The invention discloses a passenger car frame structure, comprising a box-type longitudinal beam, a cross beam, a front independent suspension cross beam, a front independent suspension mounting bracket, a chassis connector and a rear leaf spring mounting bracket, wherein the number of the box-type longitudinal beams is two, a plurality of cross beams are vertically arranged between the two box-type longitudinal beams, and a front independent suspension cross beam is arranged between one end of the two box-type longitudinal beams. The utility model has the beneficial effects that the passengercar frame is formed into a system basic frame through full stamping and box structure, and has the structural characteristics of thin, uniform, light and strong, and can simultaneously meet the change requirements of different engines. According to the invention, A large number of pipeline insertion fixing holes and pipeline insertion fixing holes are respectively arranged in the cross beam, so as to ensure that the chassis of the bus and the pipes in the bus body are fixed reliably, the insertion is more convenient, and the line arrangement is more orderly and orderly, and the weight of thebox-type longitudinal beam and the whole cross beam is reduced by the large number of fixing holes, and the production and processing cost is reduced.

Description

technical field [0001] The invention relates to a vehicle frame structure, in particular to a passenger car frame structure, and belongs to the technical field of passenger car frame structure applications. Background technique [0002] The frame structure is indispensable in the production and processing of the bus. The bus body and the chassis are connected and fixed through the frame structure to ensure the normal use of the bus. The existing bus frame structure has the following defects: [0003] 1. The current conventional front passenger car frame is not a box type, stamping structure, and its strength is relatively weak; [0004] 2. There are no holes for installing and fixing pipelines on the frame of conventional passenger cars, and they are only fixed by cable ties, which are messy and interspersed, causing great hidden dangers; [0005] 3. Since the frame and the body are fixed by rigid welding of the connectors instead of bolts, the comfort is poor; and usually...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the current conventional passenger car frame is not box-type and stamped, and its strength is relatively weak. There is no hole for installing and fixing pipelines on the conventional passenger car frame, and it is only fixed by cable ties. Messy interspersed, great hidden dangers, and because the frame and body are fixed by rigid welding of connectors instead of bolts, the comfort is poor, and usually one frame is only for one model or engine, and it is relatively difficult to adjust the crossbeam Large size, poor versatility and adaptability, and a passenger car frame structure is proposed
