Description
Technical field
The present invention relates to vehicle frame technical field more particularly to a kind of truck frames, and invention relates further specifically to be used as vehicle
The bearing beam that the load bearing component of frame uses.
Background technology
The chassis of truck generally includes vehicle frame and suspension two parts, and suspension is connected between vehicle frame and axletree, and being used for will
The load that vehicle frame is carried flexibly is placed on axletree.Well known a kind of heavy load truck vehicle frame, as shown in Fig. 2, it has
The inside of two longerons 100, longeron 100 is fixed with the connecting seat 101 of flute profile, and crossbeam A200 is inserted in connecting seat 101, crossbeam
The top connecting plate of A200 is bolted to connection together with the upper flange of connecting seat 101；Balance shaft support 300 has side
Connection otic placode 301 and supporting plate 302, side connection otic placode 301, longeron 100 and crossbeam A200 are bolted to connection together,
The bottom connecting plate of crossbeam A200, the lower wing plate of connecting seat 101 and supporting plate 302 are bolted to connection together.Such as Fig. 1
Shown, balance shaft support 300 is connect with the leaf spring 400 of suspension, and leaf spring 400 is fixed on axle 500.
When normal vehicle operation, the load that vehicle frame is carried is applied to leaf spring 400, crossbeam by balance shaft support 300
A200 only serves the effect of longitudinal beam connected, still, when vehicle bumpy road when driving, since crossbeam A200 is up and down four
A direction and longeron 100 and balance shaft support 300 are rigid connection, and the wheel torque generated in front-rear direction that jolts (jolts
Torque) balance shaft support 300 is reached first, a part reaches longeron 100 by side connection otic placode 301, and another part passes through support
Plate 302 is transmitted to through longeron connecting seat 101 on crossbeam A200.Since side connection otic placode 301 is connect by bolt with longeron 100,
Frictional force when it is fastened by bolt between faying face resists the torque that jolts, but frictional force is significantly smaller than normal pressure, thus the knot
Chalaza is smaller to the contribution for resisting the torque that jolts.101 generally use steel material of longeron connecting seat is passed by supporting plate 302
Pass jolt torque when, will produce elastic deformation, and then transfer torque to crossbeam A200, the structure of crossbeam A200 is similar to I-shaped
Steel, when by lateral torsion, the bottom connecting plate of cantilever diaphragm both sides is pressurized while tension, will produce and splits when serious
Line causes safety accident.
In view of the complexity of stress, the cast steel material of crossbeam A200 generally uses mechanical strength and good toughness, but cast steel
The casting manufacturability and processing technology of material are poor, of high cost.Although cast iron materials casting manufacturability, processing technology and at
It is advantageous in sheet, but its toughness is low, and tensile strength is low.
The anti-torsional strength of truck frame crossbeam how is improved, safety accident is reduced, while weight can not be increased again, does not increase
Adding manufacturing cost even reduces manufacturing cost just as those skilled in the art's urgent problem.
