Description
Technical field
The utility model belongs to automotive field, is the associated components of automobile, specifically a kind of automobile chassis vehicle frame.
Background technology
Automobile chassis vehicle frame is the important composition part on automobile, is the basic skeleton of automobile, by longeron, crossbeam, connection
Plate and some accessories etc. are constituted, and are connected together by welding, riveting or bolt.Automobile chassis vehicle frame supports hair
The relevant part of all sprung mass such as motivation, clutch, speed changer, steering gear and separate frame construction, via draft hitch,
Propons, back axle are supported on wheel.Suffered impact, distortion, inertia force etc. when the weight and traveling of automobile itself parts, all
Act on vehicle frame.Vehicle frame, which subjects, is transmitted to its various power and torque, and stress is complicated.Therefore, vehicle frame will have enough intensity
And rigidity, with the impact born the load of automobile and transmitted from wheel and suspension.Present automobile chassis vehicle frame one is using straight
Logical fall crossbeam type structure, the structure is although simple in construction, public welfare is good, but have that quality itself is big, assembly difficult arrangement, stress not
It is difficult to the shortcoming repaired after uniform damage；Two be to use full truss structure, and the structure is by without frame chassis and body frame
The full bearing structure collectively constituted, is welded, the architecture quality is light, passive safety is good, size knot using steel tubes
Structure flexibly, simplifies the forming process of component, but component is more, and technical matters requirement is strict, and production cost is high, and weld seam is more,
Reduce allowable stress.Therefore it provides a kind of fame dimensions flexible structure, it is easy to assembling manufacturing and maintenance, have sufficient intensity and
The multi-segment structure automobile chassis vehicle frame of rigidity seems particularly necessary.
The content of the invention
The technical problems to be solved in the utility model is, for the deficiency of existing automobile chassis vehicle frame, to design and develop one kind
Fame dimensions flexible structure, it is easy to assembling manufacturing and maintenance, there is sufficient intensity and rigidity, the automobile chassis of multisection type longitudinal beam structure
Vehicle frame.
In order to solve the above technical problems, the technical solution of the utility model is：Automobile chassis vehicle frame, including crossbeam, twice
Longeron, seat installing plate and accessory, twice longeron are fixedly connected by crossbeam, and the seat of connecting cross beam is provided between crossbeam
Installing plate, twice longeron be multistage stringer combination into bending longeron type longeron, each section of longeron by welding, riveting or bolt before
After be connected, twice longeron or so Parallel Symmetric and it is not wide set, including front longitudinal, middle longeron, middle floor side member, lengthen longeron
And floor side member, middle side rail is provided with the outside of middle longeron.
Foregoing automobile chassis vehicle frame is that the crossbeam includes the water tank sill of connection front longitudinal front end, in being arranged on
First crossbeam, second cross beam and the 3rd crossbeam between longeron, are arranged on the 4th crossbeam at middle floor side member two ends, are arranged on lengthening
5th crossbeam of longeron rear end, is arranged on the 6th crossbeam, the 7th crossbeam between floor side member, is arranged at the back door of crossbeam tail end
Longeron is stretched out at sill inner panel and back door sill outside plate, the 4th crossbeam and the 5th crossbeam two ends.
Foregoing automobile chassis vehicle frame is that motor root and stem of certain plants beam installing plate is provided with the 4th crossbeam.
Compared with the prior art, the beneficial effects of the utility model are：Twice longeron of the present utility model is by multistage longeron
Connection is combined into flexure type longeron, and length, flexibility and the cross sectional shape of each section of longeron can flexible designs, the arrangement and chi of crossbeam
It is very little also more flexible.The flexibility of body frame structure for automotive size, it is easy to manufacture and assembling, facilitates the maintaining in later stage, and can guarantee that
Enough strength and stiffness, rationally share load, improve security and applicability.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model automobile chassis vehicle frame.
Embodiment
As shown in drawings, a kind of automobile chassis vehicle frame that the utility model is related to, including crossbeam, twice longeron, seat peace
Plate and accessory are filled, twice longeron is fixedly connected by crossbeam, the seat installing plate of connecting cross beam, twice are provided between crossbeam
Longeron be multistage stringer combination into bending longeron type longeron, each section of longeron by welding, riveting or bolt before and after be connected, two
Road longeron or so Parallel Symmetric and it is not wide set, including front longitudinal 1, middle longeron 2, middle floor side member 3, lengthen longeron 4 and rear vertical
Beam 5, middle side rail 6 is provided with the middle outside of longeron 2；The crossbeam includes the water tank sill 7 of connection front longitudinal 1 front end, if
First crossbeam 8, the crossbeam 10 of second cross beam 9 and the 3rd between middle longeron 2 are put, be arranged on the middle two ends of floor side member 3 the 4th is horizontal
Beam 11, is arranged on the 5th crossbeam 12 for lengthening the rear end of longeron 4, is arranged on the 6th crossbeam 13, the 7th crossbeam between floor side member 5
14, the back door sill inner panel 15 and back door sill outside plate 16 of crossbeam tail end are arranged at, the 4th crossbeam 11 and the 5th is horizontal
Longeron is stretched out at the two ends of beam 12；Motor root and stem of certain plants beam installing plate is provided with the 4th crossbeam 11.The automobile chassis vehicle frame is by multistage longeron
Front and rear welding, riveting or bolt connection are combined into left and right twice longeron, each section of longeron length, flexibility and sectional dimension can from
By setting, dimensional structure is flexible；Meanwhile, the arrangement and dimensional structure of crossbeam and seat installing plate are also compared with freedom and flexibility.Such group
Into Parallel Symmetric not Periphery frame, it is easy to manufacture and assemble, facilitate the maintaining in later stage, and can guarantee that enough strong
Degree and rigidity, rationally share load, improve security and applicability.
