Abstract
The utility model relates to an automotive chassis frame which is the variable cross-section single camber arch chassis frame. The chassis frame consists of a beam and girders, and the beam is arranged between the two girders. The chassis frame is characterized in that the girders at the front section, the middle part and the tail part of the frame are all uniform cross-section equal-height trough girders, the girder at the central line of back wheels of the chassis frame is the variable cross-section trough girder, and the chassis frame is further provided with a camber arch. The structure can increase the dynamic travel of a rear suspension frame and reduce the height from the upper surface of the frame to the ground.
Description
Technical field
The utility model relates to a kind of car chassis vehicle frame, a kind of specifically variable section list camber arch chassis frame.
Background technology
The chassis frame of automobile is one of major part of automobile, and the structure of chassis frame can directly influence the structure of automobile.The car chassis vehicle frame generally all is made up of crossbeam and longeron, cross beam frame is between two longerons, two longerons of existing car chassis vehicle frame are wide straight longerons, processing technology is simple, but in car chassis more than 9 meters, straight girder work vehicle frame exists the floor too high, and suspension moves the too small shortcoming of stroke.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming of above prior art, propose a kind of moving stroke that increases rear suspension, reduce the variable section list camber arch chassis frame of vehicle frame upper surface terrain clearance.
The technical scheme that the utility model solves above technical matters is:
Variable section list camber arch chassis frame is made up of crossbeam and longeron, and cross beam frame is between two longerons, and vehicle frame leading portion, middle part and afterbody longeron are the contour grooved longeron of uniform cross section, and vehicle frame trailing wheel centerline longeron is a variable section grooved longeron, and is provided with camber arch.
Trailing wheel centerline longeron lower aerofoil camber arch up, relatively front end and back segment lower aerofoil improve 80mm, to increase the moving stroke of rear suspension, help the reduction of vehicle frame upper surface terrain clearance in the master layout; Trailing wheel centerline longeron top airfoil camber arch up, front end and back segment top airfoil are raised 40mm relatively, the one, guarantee that it is bending stiffness that longeron has enough section heights, the 2nd, raise 40mm, can flush with automobile body floor or skeleton, do not influence the layout on floor, and realize that fully floor, the interior front and back of car is contour, the purpose of back axle place fat pipe.
The utility model has the advantages that: the both general existing longeron mould of structure of the present utility model, again can be in the steel spring in the fixing forward and backward suspension in longeron side, thereby realize reducing forward and backward suspension height, reduced the height of car load, realize the target of three grades of passenger dooies of marking time, make things convenient for passenger getting on/off.Because leading portion, stage casing and afterbody longeron are straight type longeron, two parallel wide settings of longeron, the trailing wheel place is a variable section list camber arch longeron, the whole sectional type composite die that adopts of longeron, reduced productive costs, processing is simple, is convenient to install, the work in-process length overall can realize freely changing simultaneously, and the wheelbase setting range is also big.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment one
The structure of present embodiment as shown in Figure 1, a kind of variable section list camber arch chassis frame is made up of crossbeam 1 and longeron 2,1 on crossbeam is between two longerons 2.Vehicle frame leading portion, middle part and afterbody longeron are the contour grooved longeron of uniform cross section, and are that the trailing wheel centerline adopts variable section grooved longeron 3 at the rear portion, and are provided with camber arch 4.The lower aerofoil camber arch of trailing wheel centerline variable section grooved longeron 3 up, relatively front end and rear end lower aerofoil improve 80mm, to increase the moving stroke of rear suspension, help the reduction of vehicle frame upper surface terrain clearance in the master layout.Trailing wheel centerline variable section grooved longeron 3 top airfoil camber arch up, front end and back segment top airfoil are raised 40mm relatively, the one, guarantee that it is bending stiffness that longeron has enough section heights, the 2nd, raise 40mm, can flush with automobile body floor or skeleton, do not influence the layout on floor, and realize that fully floor, the interior front and back of car is contour, the purpose of back axle place fat pipe.
Because leading portion, stage casing and afterbody longeron are straight type longeron, two parallel wide settings of longeron, the trailing wheel place is a variable section list camber arch longeron, the whole sectional type composite die that adopts of longeron, reduced productive costs, processing is simple, is convenient to install, the work in-process length overall can realize freely changing simultaneously, and the wheelbase setting range is also big.
The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
