Abstract
The utility model belonging to automobile field is a ladder shaped chassis of automobile, which comprises a horizontal beam, vertical beams of two sides, wherein the two vertical beams are connected with each other by the horizontal beam, forming a carriage body; the carriage body taking a front axle as a boundary is provided with a width of wide front and narrow end. Because that the carriage is provided with the width of wide front and narrow end, a leaf spring of a rear suspension can be arranged outside the vertical beam, the arrangement of the rear suspension is relatively reasonable; the ladder shaped chassis of wide front and narrow end is also helpful for saving processing material.
Description
Technical field
The utility model belongs to automotive field, is the associated components of automobile, the trapezoidal chassis frame of a kind of specifically automobile.
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 all is made up of crossbeam and longeron, and cross beam frame constitutes vehicle frame between two longerons.In existing car chassis vehicle frame, the car chassis vehicle frame adopts wide girder work, the vertical main riveted joint formation car chassis vehicle frame that adopts of crossbeam and wide longeron.The car chassis vehicle frame of the wide girder work of this kind, can not effectively reduce plane terrain clearance on the vehicle frame, the steel spring of rear suspension also can only be arranged in the longeron inboard, is unfavorable for suspension arrangement, and the car chassis vehicle frame of wide girder work also is unfavorable for economical with materials simultaneously.Therefore, existing car chassis vehicle frame haves much room for improvement.
Summary of the invention
Purpose of the present invention is exactly the shortcoming that exists at existing car chassis vehicle frame, but proposes a kind of economical with materials, help the trapezoidal chassis frame of automobile of suspension arrangement.
The purpose of this utility model can be achieved through the following technical solutions:
The trapezoidal chassis frame of a kind of automobile comprises crossbeam, two side girders, and two longerons connect into vehicle frame by crossbeam, and vehicle frame is the boundary with the propons, and its width is anterior wide, and the rear portion is narrow.
The purpose of this utility model can also further realize by following technical measures:
The trapezoidal chassis frame of aforesaid automobile, wherein said vehicle frame is the boundary with 500～1000 millimeters of propons center back, the vehicle frame before this boundary is wide vehicle frame; With 1000～3000 millimeters of propons center back is the boundary, and the vehicle frame behind this boundary is narrow vehicle frame.
The trapezoidal chassis frame of aforesaid automobile, wherein said vehicle frame longeron end face height is 100～200 millimeters.
The trapezoidal chassis frame of aforesaid automobile, wherein said vehicle frame wheelbase are 2600 millimeters-4200 millimeters.
The trapezoidal chassis frame of aforesaid automobile, wherein said vehicle frame front overhang length are 600 millimeters-1700 millimeters.
Advantage of the present utility model is: because the vehicle frame front portion is wide, the rear portion is narrow, forms trapezoidal chassis frame, and the steel spring of rear suspension can be arranged in the longeron outside, and suspension arrangement is comparatively reasonable; The narrow trapezoidal chassis frame in anterior wide rear portion also helps saving work material.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of longeron;
Among the figure: wide vehicle frames before 1 crossbeam, 2 longerons, 3 propons, 4,
The narrow vehicle frame in 5 backs.
The specific embodiment
Embodiment one
Figure 1 shows that the structural representation of an embodiment of the utility model, Fig. 2 is the structural representation of its longeron, and the trapezoidal chassis frame of a kind of automobile comprises crossbeam 1, two longerons 2, two longerons 2 connect into vehicle frame by crossbeam 1, between crossbeam 1 and two longerons 2 based on riveted joint.Vehicle frame is the boundary with the propons, and its width is anterior wide, and the rear portion is narrow, forms the ladder type frame body of the narrow vehicle frame 5 of wide vehicle frame 4 and back before containing.Preceding wide vehicle frame 4 is the boundary for 500～1000 millimeters with propons 3 center back, and the vehicle frame before this boundary is preceding wide vehicle frame 4.The narrow vehicle frame 5 in back is the boundary with 1000～3000 millimeters of propons center back, and the vehicle frame behind this boundary is the narrow vehicle frame 5 in back.After two longerons 2 connected into vehicle frame by crossbeam 1, the formation wheelbase was 2600 millimeters-4200 millimeters a vehicle frame.Vehicle frame longeron 2 end face height are 100～200 millimeters.Vehicle frame front overhang length is 600 millimeters-1700 millimeters
Specifically add man-hour, longeron 2 is to adopt mould compression moulding, and its structure after every longeron 2 machine-shapings, connects into vehicle frame by crossbeam 1 with two longerons 2 as shown in Figure 2, forms front wide and rear narrow ladder type frame body.
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 scope of the utility model protection.
