Abstract

The utility model provides a frame which comprises two longitudinal beams and a plurality of intermediate cross beams, wherein each longitudinal beam is provided with an airfoil and a side; and two ends of each intermediate cross beam are fixedly arranged on the inner side of the longitudinal beam. The frame is simple in structure, convenient to install, good in loading capability and high in reliability.

Description

A kind of vehicle frame

Technical field

The utility model relates to a kind of vehicle frame, and is especially relevant with the connection structure of the longeron of vehicle frame and center member.

Background technology

At present, the basic structure of carriage frame is made up of two longerons (left longeron and right vertical beam), some center members and some brackets usually.As shown in Figure 1, longeron 1 and center member 2 have constituted the agent structure of vehicle frame.Longeron 1 cross section is standing counts " Contraband " type, is divided into top airfoil, lower aerofoil and side.Center member 2 equally also has top airfoil, lower aerofoil and side.Center member 2 is provided with perpendicular to longeron 1, and in its end, the top airfoil of center member 2 is resisted against the below of longeron 1 top airfoil, and the lower aerofoil of center member 2 is resisted against the top of longeron 1 lower aerofoil.Offer through hole respectively on the lower aerofoil on longeron 1 and the center member 2, re-using bolt 3 (detachably) or rivet (on-dismountable) is fixed in center member 2 on the aerofoil of longeron 1.Though this vehicle frame is simple in structure, easy for installation, perforate on lower aerofoil on the longeron has reduced the load capacity of longeron, and longeron is destroyed from last lower aerofoil easily, and reliability is low.

Therefore, how to provide that a kind of load capacity is better, the higher vehicle frame of safety has become those skilled in the art's problem to be solved.

The utility model content

To the technical matters of above-mentioned proposition, the purpose of the utility model be to provide a kind of simple in structure, easy for installation, load capacity is good, the vehicle frame that reliability is high.

For achieving the above object, the utility model provides a kind of vehicle frame, comprises two longerons and many center members, and wherein said longeron has aerofoil and side, and the both ends of said center member are fixedly set on the medial surface of said longeron.

According to the design of the utility model, the cross section of said longeron is " Contraband " type, includes top airfoil, lower aerofoil and side.

Design according to the utility model; The both ends of said center member have linkage unit; Said linkage unit is for extended from said center member end and be parallel to the connecting panel of said longeron medial surface, and said connecting panel is fixedly set on the medial surface of said longeron.

According to the design of the utility model, the both ends of said center member have linkage unit, and an end of said linkage unit is fixedly set in the medial surface of said longeron, and the other end is captiveed joint with an end of said center member.

Design according to the utility model; Said linkage unit is an adapter plate; Said adapter plate has first joint face and second joint face of one, and wherein said first joint face is captiveed joint with said center member end, and said second joint face is captiveed joint with said longeron medial surface.

According to the design of the utility model, be connected through bolt or rivet between said center member and the said longeron medial surface.

The vehicle frame of the utility model has beneficial effect and really is: the fixed position of center member is become the side by the last lower aerofoil of longeron; Common practise according to this area; Carry out operation such as perforate is less than in last lower aerofoil drilling the influence of longeron load capacity and does in the side; Therefore this vehicle frame is with respect to traditional frame optimization, and the ability of bearing load promotes greatly, has improved the reliability of vehicle frame.

The specific embodiment

For ease of better understanding the utility model, combine accompanying drawing that the preferred embodiment of the utility model is specified as follows at present:

First embodiment

Please with reference to Fig. 2 and Fig. 3, wherein Fig. 2 is a vehicle frame scheme drawing among the utility model first embodiment; Fig. 3 is the center member scheme drawing of vehicle frame among the utility model first embodiment.Like Fig. 2 and shown in Figure 3, the vehicle frame of present embodiment comprises longeron 1 and center member 2, and wherein longeron 1 has aerofoil and side, and center member 2 is arranged on the medial surface of longeron 1.As shown in Figure 2, the cross section of longeron 1 is " Contraband " type in the present embodiment, includes top airfoil, lower aerofoil and side.Center member 2 also has top airfoil, lower aerofoil and side.For guaranteeing the bonded assembly reliability, the top of the below of the top airfoil of center member 2 and longeron 1 top airfoil, the lower aerofoil of center member 2 and longeron 1 lower aerofoil all must keep a determining deviation.Two ends at center member 2 have linkage unit, and are in the present embodiment as shown in Figure 3, and this linkage unit can be extended and be parallel to the connecting panel 4 of longeron 1 medial surface from center member 2 ends.Correspondence offers the through hole (not shown) on longeron 1 side and connecting panel 4, pass through hole with longeron 1 and center member 2 captive joints through bolt 3, but the utility model is not limited to this, and the user also can use rivet to connect.

Second embodiment

Please with reference to Fig. 4, Fig. 4 is a vehicle frame intention among the utility model second embodiment.As shown in Figure 4; Basic identical among the chassis structure in the present embodiment and first embodiment, difference is that the both ends of center member have linkage unit in the present embodiment; One end of linkage unit is fixedly set in the medial surface of longeron 1, and the other end is captiveed joint with an end of center member 2.As shown in Figure 4; This linkage unit is an adapter plate 5; Adapter plate 5 has first joint face 51 and second joint face 52, and wherein first joint face 51 is captiveed joint with center member 2 ends, and second joint face 52 is captiveed joint (mounting means with first embodiment) with the medial surface of longeron 1.On the side of longeron 1, first joint face 51, second joint face 52 and center member 2 ends, all offer the through hole (not shown), use rivet to connect, longeron 1 and center member 2 is fixing through adapter plate 5.

Above-described; Be merely the preferred embodiment of the utility model; Be not in order to limit the scope of the utility model; Be that every simple, equivalence of doing according to the claims and the description of the utility model application changes and modification, all fall into the claim protection domain of the utility model patent.
