Abstract
The utility model provides a kind of semi-trailer frame, be made up of many crossbeams, load-bearing longeron and frame panel, described crossbeam is that flat type runs through crossbeam, described load-bearing longeron is arranged at intervals with the perforation of multiple crossbeam, described frame panel die casting undulate base plate, wherein, many described flat types run through crossbeam and are located in multiple crossbeam perforation of described load-bearing longeron respectively, described frame panel is laid on described flat type and runs through above crossbeam, and the upper flange of described load-bearing longeron is arranged on described hogbacked floor bottom and is positioned at the groove of its bottom surface.This semi-trailer frame have design science, rational in infrastructure, make the advantage simple, load-carrying capacity is strong.
Description
Technical field
The utility model relates to a kind of body frame structure for automotive, specifically, relate to a kind of semi-trailer frame.
Background technology
The semi-trailer frame had now comprises load-bearing longeron more, runs through crossbeam and frame panel.Along vehicle body lateral cross section, as shown in Figure 1, described in run through crossbeam 2 and mostly be W type and run through crossbeam, this runs through the top that crossbeam 2 is located in described load-bearing longeron 1, and frame panel 3 is laid on described W type to be run through above crossbeam.W type runs through crossbeam to be produced complicated, and need first bending then just to use particular manufacturing craft shaping, production efficiency is low; And the through hole running through load-bearing longeron 1 is greater than the cross-sectional area running through crossbeam 2, describedly run through crossbeam 2 and there is gap described load-bearing longeron 1 junction, when described frame panel 3 is laid on described upper flange 11 place, described frame panel 3 and described W type run through crossbeam can not close contact, when causing described frame panel 3 lade, described gap place easily subsides, and Long-Time Service causes frame panel 3 to be out of shape, and impact uses.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thus provide a kind of design science, rational in infrastructure, make the semi-trailer frame simple, load-carrying capacity is strong.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of semi-trailer frame, by many crossbeams, load-bearing longeron and frame panel are formed, described crossbeam is that flat type runs through crossbeam, described load-bearing longeron is arranged at intervals with the perforation of multiple crossbeam, described frame panel die casting undulate base plate, wherein, many described flat types run through crossbeam and are located in multiple crossbeam perforation of described load-bearing longeron respectively, described frame panel is laid on described flat type and runs through above crossbeam, the upper flange of described load-bearing longeron is arranged on described hogbacked floor bottom and is positioned at the groove of its bottom surface.
Based on above-mentioned, many described flat types run through crossbeam and are parallel to each other and vertical described load-bearing longeron.
Based on above-mentioned, multiple described crossbeam perforation are set in qually spaced in the web top of described load-bearing longeron.
Based on above-mentioned, described hogbacked floor is the base plate with multiple longitudinal fluting, and multiple described longitudinal fluting is set parallel to each other and groove depth is identical.
The utility model hinge structure has substantive distinguishing features and progress, specifically, the utility model employing flat type runs through crossbeam and replaces traditional beam structure, described flat type runs through crossbeam and makes simple, is located in the crossbeam perforation of described load-bearing longeron, is convenient to lay frame panel, described frame panel is hogbacked floor simultaneously, described frame panel is laid on described flat type when running through on crossbeam, and the two can be combined closely, and does not stay gap; Described frame panel is hogbacked floor simultaneously, the friction force that can increase between frame panel and goods prevents goods from sliding, simultaneously frame panel and flat type run through crossbeam and form net structure, increase the load-carrying capacity of vehicle, its have design science, rational in infrastructure, make the advantage simple, load-carrying capacity is strong.

Fig. 2 is the structural representation of semi-trailer frame cross-sectional plane in the utility model.
Detailed description of the invention
Below by detailed description of the invention, the technical solution of the utility model is described in further detail.
As shown in Figure 2, a kind of semi-trailer frame, is made up of many crossbeams 2, load-bearing longeron 1 and frame panel 3, and this semi-trailer frame is provided with load-bearing longeron 1 described in a pair, and load-bearing longeron 1 described in a pair be arranged in parallel formation main body of vehicle frame.Described crossbeam 2 is that flat type runs through crossbeam, and this flat type runs through crossbeam and makes simple.Described load-bearing longeron 1 is arranged at intervals with the perforation of multiple crossbeam, wherein, many described flat types run through crossbeam and are located in multiple crossbeam perforation of described load-bearing longeron 1 respectively, the diameter of described crossbeam perforation runs through horizontal depth of beam slightly larger than described flat type, be convenient to wear, make simultaneously described flat type run through crossbeam can with described load-bearing longeron close contact.Described frame panel 3 die casting undulate base plate, described frame panel 3 is laid on described flat type and runs through above crossbeam 2, and the upper flange 11 of described load-bearing longeron 1 is arranged on described hogbacked floor bottom and is positioned at the groove 31 of its bottom surface; Make whole hogbacked floor and described flat type run through crossbeam close contact with this, prevent because of both there is gap, cause the cabin floor when arrangement of goods easily to cave in.
Structure preferential in the present embodiment is that many described flat types run through crossbeam and are parallel to each other and vertical described load-bearing longeron 1, makes load-bearing longeron 1 and many described flat types described in a pair run through crossbeam and forms body frame structure for automotive, and guarantee vehicle frame uniform force, structure is attractive in appearance.
In the present embodiment, multiple described crossbeam perforation are set in qually spaced in the web top of described load-bearing longeron 1, ensure that many described flat types run through crossbeam spaced set, ensure described frame panel uniform force.
Described hogbacked floor is the base plate with multiple longitudinal fluting 31, multiple described longitudinal fluting 31 is set parallel to each other and groove depth is identical, make the upper surface of whole hogbacked floor parallel with this, both facilitated lade, increase the friction force that goods contacts with described hogbacked floor simultaneously.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
