Description

A kind of automobile chassis frame
Technical field
The utility model relates to automotive field, particularly, relates to a kind of automobile chassis frame.
Background technology
The body structure of modern automobile can be divided into two types of bearing-type and non-bearing formulas.For the automobile of body-chassis frame construction, vehicle frame is its important component part.Vehicle frame is the assembling basis of whole automobile, and assembly parts such as driving engine, change-speed box, transmission shaft, front and back bridge, vehicle body are installed on it.Because vehicle frame is the assembling basis of whole automobile, bear the various load of car interior-exterior, so require vehicle frame must satisfy the strength and stiffness requirement.
Vehicle frame is made up of with a plurality of crossbeams that are connected two curb girders two curb girders usually.Two curb girders of vehicle frame and front cross rail form the installing space of cooling system jointly.Because existing vehicle frame is processed by sheet metal component usually; So in order to satisfy the strength and stiffness requirement of vehicle frame, two curb girders design than broad usually, thereby at the width that has reduced under the fixing situation of vehicle frame overall width between two curb girders; Thereby cause the width of said installing space to diminish; Dwindle the installing space of cooling system, caused to install the cooling system of high-powered engine, and then hindered the power upgrading of automobile.
The utility model content
The purpose of the utility model provides a kind of automobile chassis frame, and this automobile chassis frame can enlarge the installing space of cooling system.
To achieve these goals; The utility model provides a kind of automobile chassis frame, and this automobile chassis frame comprises front vehicle frame and back vehicle frame, and said front vehicle frame is captiveed joint with said back vehicle frame; Said front vehicle frame comprises front cross rail and two curb girders; Said two curb girders lay respectively at the both sides of said front cross rail and captive joint with said front cross rail, and said front cross rail and two curb girders form the installing space of cooling system jointly, and wherein said curb girder is a Casting Parts.
Preferably, be integrated with front body overhang on the said curb girder and put support.
Preferably, be integrated with leaf spring front frame and front suspension front frame on the said curb girder.
Preferably, be connected with tie-beam between said two curb girders.
Preferably, be respectively arranged with the connection support on said two curb girders, the two ends of said tie-beam respectively with said two curb girders on be connected the support captive joint.
Preferably, said connection support and said curb girder are integrally formed.
Preferably, said tie-beam downwarping.
It is thus clear that the installing space of cooling system is formed by front cross rail and two curb girders of front vehicle frame, and curb girder is a Casting Parts.Because curb girder is a Casting Parts, so compare with the curb girder that existing sheet metal component is processed, curb girder need not design very widely; Narrower curb girder just can satisfy the strength and stiffness requirement of vehicle frame; Thereby under the situation that the vehicle frame overall width is fixed, can increase two width between the curb girder, thereby increase the width of installing space, enlarge the installing space of cooling system; Make the cooling system that high-powered engine is installed become possibility, and then promoted the power upgrading of automobile.
Other feature and advantage of the utility model will partly specify in the specific embodiment subsequently.
