Abstract
The utility model discloses a bear chassis frame entirely, including the frame main part, still include along the technology roof beam of frame main part longitudinal distribution, through increasing along the technology roof beam of frame main part longitudinal distribution, under the prerequisite that does not change current frame major structure, improve fore -and -aft intensity of whole chassis frame and rigidity, satisfy the rigidity requirement of chassis frame production, hoist and mount and transportation, when chassis frame and automobile body are assembled, get rid of the technology roof beam, just can normally assemble, chassis frame precision height, need further not rectify and inspect. Furtherly, technology roof beam detachable mounting means can the simplifying processing roof beam the installation, improve the utilization ratio of technology roof beam.
Description
Technical field
The utility model relates to bus frame structure, particularly relates to the full bearing chassis vehicle frame of a kind of passenger vehicle.
Background technology
Present full-bearing type chassis frame is generally formed by square tube and the welding of sheet metal parts, and whole vehicle frame is longer, generally all on 10 meters.When making, first carrying out monolithic welding, the monolithic Combination Welding of then welding forms complete chassis frame, then other parts of chassis frame and passenger vehicle being assembled.But because whole vehicle frame is long, therefore in production, lifting, transportation, easily there is excessive distortion before and after base plate vehicle frame, occur when in the end assembling with vehicle body that dislocation can not install phenomenon, need to carry out before assembling correcting and checking, just can assemble after reaching standard.
Utility model content
The utility model, in order to solve existing chassis frame problem on deformation in production, lifting, transportation, provides one bearing chassis vehicle frame entirely, improves the stability of chassis frame, meet the rigid requirements produced, lift and transport.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of full bearing chassis vehicle frame, comprise main body of vehicle frame, also comprise the technique beam along main body of vehicle frame genesis analysis, by increasing the technique beam along main body of vehicle frame genesis analysis, under the prerequisite not changing existing main body of vehicle frame structure, improve intensity and the rigidity of whole chassis frame longitudinal direction, meet the rigid requirements that chassis frame is produced, lifted and transport, when chassis frame and vehicle body are assembled, technique beam is removed, just normally can assemble, chassis frame precision is high, not need to correct further and inspection.Further, described main body of vehicle frame comprises the leading portion assembly connected successively, stage casing assembly, back segment assembly, described technique beam is fixed on stage casing assembly, generally according to passenger vehicle front and back wheel, main body of vehicle frame is divided into leading portion, stage casing, back segment three part, wherein the length of stage casing assembly is longer, in production, easily deformation is there is in lifting and transportation, therefore technique beam is fixed on stage casing assembly by us, improve intensity and the rigidity of stage casing assembly, technique beam is comb teeth-shaped, comprise a crossbeam and multiple pillar stiffener be connected with beam vertical, technique beam is connected with stage casing assembly by beam-ends and pillar stiffener end, by pillar stiffener and crossbeam, multiple positions of stage casing assembly are fixed, further increase intensity and the rigidity of stage casing assembly.
As a kind of preferred version of full bearing chassis vehicle frame described in the utility model, described technique beam and main body of vehicle frame are welded and fixed, firm and reliable connection, there is very high bending stiffness and firm and reliable connection, be out of shape for preventing chassis frame and provide guarantee, when later stage chassis frame and vehicle body are assembled, need technique beam to cut away, generally adopt gas flame cuttiug.
As a kind of preferred version of full bearing chassis vehicle frame described in the utility model, described technique beam and main body of vehicle frame detachably fixedly mount, and chassis frame can be prevented to be out of shape on the one hand, are conducive to removing technique beam when assembling with vehicle body on the other hand.
As a kind of preferred version of full bearing chassis vehicle frame described in the utility model, described crossbeam two ends and pillar stiffener end are provided with connecting panel, the position that stage casing assembly is connected with crossbeam and pillar stiffener is also provided with connecting panel, above-mentioned connecting panel is provided with through connecting bore, is fixed through connecting bore by bolt.
Beneficial effect:
Full bearing chassis vehicle frame described in the utility model is by increasing the technique beam along main body of vehicle frame genesis analysis, under the prerequisite not changing existing main body of vehicle frame structure, improve intensity and the rigidity of whole chassis frame longitudinal direction, meet the rigid requirements that chassis frame is produced, lifted and transport, when chassis frame and vehicle body are assembled, technique beam removed, just can normally assemble, chassis frame precision is high, do not need to correct further and check.Further, technique beam detouchable mounting means can the installation process of Simplified flowsheet beam, improves the degree of utilization of technique beam.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
As shown in the figure, a kind of full bearing chassis vehicle frame, comprises main body of vehicle frame 1 and the technique beam 2 along main body of vehicle frame genesis analysis.Main body of vehicle frame 1 comprises the leading portion assembly 1.1, stage casing assembly 1.2, the back segment assembly 1.3 that connect successively, technique beam 2 can be fixed on leading portion assembly 1.1 and/or stage casing assembly 1.2 and/or back segment assembly 1.3, because the length of stage casing assembly is longer, the application force be subject in production, lifting, transportation is larger, the most yielding, therefore technique beam is mainly arranged on stage casing assembly 1.2.By increasing the technique beam along main body of vehicle frame genesis analysis, under the prerequisite not changing existing main body of vehicle frame structure, improving intensity and the rigidity of whole chassis frame longitudinal direction, meeting the rigid requirements that chassis frame is produced, lifted and transport.
Further, technique beam 2 is in comb teeth-shaped, comprise a crossbeam 2.1 and multiple pillar stiffener 2.2 be connected with beam vertical, crossbeam two ends and pillar stiffener end are provided with connecting panel 2.3, the position that stage casing assembly is connected with crossbeam and pillar stiffener is also provided with connecting panel 2.3, above-mentioned connecting panel is provided with through connecting bore, is fixed through connecting bore by bolt.Connecting panel increases the area of contact of technique beam and stage casing assembly, connects more firm.
Although be illustrated embodiment of the present utility model in specification sheets, these embodiments just as prompting, should not limit protection domain of the present utility model.In the scope not departing from the utility model aim, carry out various omission, displacement and change all should be included in protection domain of the present utility model.
